Instructions for Post-TED (2450) Form
This section of the CIBMTR Forms Instruction Manual is intended to be a resource for
completing the Post-TED Form.

Post-TED
Transplant centers participating in the CIBMTR must submit a Post-TED (2450) Form
for recipients who meet any of the following criteria:
•
•

•

•

Recipient receives a transplant at a United States center designated as a TEDonly center.
Recipient receives a transplant at a United States center designated
as Comprehensive Report Form center but has been assigned to the TED track
by the Form Selection Algorithm.
Recipient receives an allogeneic transplant at a United States center designated
as Comprehensive Report Form center but has not consented to participate in
research.
Recipient receives a transplant at an international center, has consented to
participate in research, and has been assigned to the TED track by the Form
Selection Algorithm.

The Post-TED fulfills the requirements of the SCTOD for recipients meeting any of the
above criteria. For more information regarding the SCTOD, see SCTOD Requirements.
For more information, including information on the TED and Comprehensive Report
Form Selection Algorithm, see the Data Management Guide.
The Post-TED (2450) Form must be completed at the following time points: 100 days,
six months, and annually post-infusion. These forms should be completed as closely to
these time points as possible. The structure of the TED Forms is such that each form
should fit on a timeline with distinct start and stop dates that do not overlap any other
forms, except in the case of a subsequent infusion.
Reporting Data for Each Reporting Period
If the Post-TED (2450) Form is being completed for the Day 100 reporting period,
answers to all questions should reflect Day +1 until the reported Day 100 contact date.
For the six-month or annual evaluation, the answers to all questions should reflect since

the contact date for the prior reporting period until the reported contact date for the
current reporting period.
Subsequent Infusions
If the recipient received a subsequent infusion (excluding an autologous rescue), the
answers to all questions should reflect the clinical status of the recipient the day prior to
the start of the preparative regimen or, if no preparative regimen was given, the
answers to all questions should reflect the clinical status of the recipient the day prior to
infusion.
Subsequent HCT
If a recipient receives a subsequent HCT between Post-TED time points (100 day, six
months, annually), the TED form sequence will start over again with another Pre-TED.
However, if the recipient receives an autologous HCT as a result of a poor graft or graft
failure, the TED form sequence will not start over again. Generally, this type of infusion
(autologous rescue) is used to treat the recipient’s poor graft response, rather than to
treat the recipient’s disease.
Contact the CIBMTR Customer Service Center if the subsequent Pre-TED does not
come due automatically.
Non-Malignant Diseases
If the HCT being reported was given to treat a non-malignant disease (as reported on
the Pre-TED Disease Classification (2402) Form), do not complete the following
sections of the Post-TED (2450) Form:
•
•

Q41 – 66: Disease Assessment at the Time of Best Response to Infusion
Q67 – 73: First Relapse or Progression Post-Infusion
Q77 – 84: Post-Infusion Intervention for Disease
Q85 – 91: Post-Infusion Treatment Given to Prevent Relapse or Progression
Q92 – 95: Fecal Microbiota Transplant (FMT)
Q96 – 98: Current Disease Status

Lost to Follow-Up
Occasionally, centers may lose contact with recipients for a variety of reasons, including
the recipient’s moving, changing physicians, or death. If contact with a recipient appears
lost, please consider calling the recipient at home or work, sending a letter,
communicating with the treating or referring physician, or contacting the hospital billing
department. If no documentation exists and several unsuccessful attempts have been
made to contact the recipient, they are considered lost to follow-up and the form may be
marked as such using the Lost to Follow-Up tool in FormsNet3SM for each reporting
period in which no contact exists.

Forms Instructions Manual released. Version 8
corresponds to revision 9 of the Form 2450.

Q1 – 2: Survival
The date of actual contact with the recipient to determine medical status for this followup report is based on a medical evaluation conducted by a clinician with responsibility
for the recipient’s care. Report the date of the medical evaluation performed closest to
the designated time period of the form (e.g., Day+100, 6 months, or annual follow-up
visit). Time windows are provided to guide selection of dates for reporting purposes.

CIBMTR Form 2450

Recipients are not always seen within the time windows used for reporting follow-up
dates, and some discretion is therefore required when determining which date to report.
If the recipient is not seen within the time windows, report the date closest to the date of
contact within reason.
If the Post-TED Form reports a subsequent infusion (transplant or genetically modified
cellular therapy), report the date of latest follow-up as the day prior to the start of the
preparative regimen / systemic therapy. If no preparative regimen or conditioning /
systemic therapy was given, report the day prior to infusion as the date of contact.
No Documentation of Contact Date
The contact date data field cannot be left blank and is required to be reported. In cases
where the recipient passed away and there is no documentation to report the date of
death, the guidelines for reporting estimated dates must be used.
Reporting Latest Follow-Up
When reporting the date of latest follow-up prior to a subsequent infusion (HCT or
cellular therapy), report the date specified above regardless of whether there is actual
patient contact on the date. This is an exception to the standard date of follow-up
reporting to ensure all dates are captured within the sequence of forms.
Reporting the 1-Year Date of Contact
If this form is being completed for the 1-year reporting period, ensure the reported
contact date is > Day 365. Review the 1-Year Date of Contact instructions below for
additional information.
Reporting Contact Dates Reporting Instruction Overview
Review the Contact Dates Reporting Instruction Overview for additional information on
reporting contact dates for recipient death, subsequent infusions, and various contact
date reporting examples.
Question 1: Date of actual contact with the recipient to determine medical status
for this follow-up report
Report the date of actual contact with recipient to determine medical status for this
follow-up report. Acceptable evaluations include those from the transplant center,
referring physician, or other physician currently assuming responsibility for the
recipient’s care. Please capture a physician evaluation that falls within the appropriate
range, if possible, rather than other types of patient contact that may be closer to the
actual time point. If an evaluation was not performed at Day+100, at 6 months, or on
the HCT anniversary, choose the date of the visit closest to the actual time point.
If the recipient has not been seen by a clinician during the reporting period but the
survival status is known, complete the Survival Tool referenced in the CIBMTR Data
Management Guide.

In general, the date of contact should be reported as close to the 100-day, 6 month, or
annual anniversary to transplant as possible. Report the date of actual contact with the
recipient to evaluate medical status for the reporting period. In the absence of contact
with a clinician, other types of contact may include a documented phone call with the
recipient, a laboratory evaluation, or any other documented recipient interaction on the
date reported. If there was no contact on the exact time point, choose the date of
contact closest to the actual time point. Below, the guidelines show an ideal
approximate range for reporting each post-transplant time point:
Time Point

Approximate Range

100 days

+/- 15 days (Day 85-115)

6 months

+/- 30 days (Day 150-210)

1 year

+ 60 days (Day 366 – 425)

Annual reporting 2+ years +/- 30 days (Months 23-25, 35-37, etc.)
Date of Contact and Death
In the case of recipient death, the date of death should be reported as the date of
contact regardless of the time until the ideal date of contact. The date of death should
be reported no matter where the death took place (inpatient at the transplant facility, at
an outside hospital, in a hospice setting, or within the recipient’s home).
If the death occurred at an outside location and records of death are not available, the
dictated date of death within a physician note may be reported. If the progress notes
detailing the circumstances of death are available, request these records. These
records are useful for completing required follow-up data fields and the cause of death
data fields on this form. If the exact date of death is not known, use the processed
described for reporting partial or unknown dates, see General Instructions, General
Guidelines for Completing Forms.
Date of Contact and Subsequent Infusion
If the recipient has a subsequent infusion (HCT or cellular therapy), the date of contact
will depend on the type of subsequent infusion. If the subsequent infusion is an HCT or
genetically modified cellular therapy (e.g. CAR-T), report the date of contact as the day
before the preparative regimen / lymphodepleting therapy begins for the subsequent
infusion. If no preparative regimen / lymphodepleting therapy is given, report the date of
contact as the day before the subsequent infusion. In these cases, actual contact on
that day is not required, and the day prior to the initiation of the preparative regimen (or
infusion, if no preparative regimen / lymphodepleting therapy) should be reported. This
allows every day to be covered by a reporting period but prevents overlap between

Q4 – 6: Initial ANC Recovery
Initial ANC Recovery
The Initial ANC Recovery questions can only be completed on the 100-day, 6-month, 1year, and 2-year follow-up forms. These questions will be skipped for all subsequent
reporting periods. Did late graft failure occur must be answered on all follow-up forms.
Initial ANC Recovery
Recovery, as reported in this section, does not distinguish between allogeneic
engraftment (blood and stem cells of donor origin) and autologous engraftment (blood
and stem cells of host origin). To demonstrate engraftment for allogeneic recipients,
particularly non-myeloablative or reduced intensity approaches, chimerism tests must
be done. These measure the quantity of donor cells relative to the quantity of host
(recipient) cells. While ANC usually represents donor cells in allogeneic HCT, it cannot
be proven without chimerism studies.
Combined Follow-Up
In scenarios where a cellular therapy was given after an HCT and this form is now being
completed based on the subsequent cellular therapy date, these questions do not apply
and are disabled.
ANC recovery is defined as an absolute neutrophil count (ANC) of ≥ 0.5 × 109/L
(500/mm3) for three consecutive laboratory values obtained on different days. Date
of ANC recovery is the date of the first of three consecutive laboratory values where
the ANC is ≥ 0.5 × 109/L. At some institutions, the laboratory reports display
the ANC value once there are sufficient white blood cells to perform a differential count.
At other institutions, the laboratory reports do not display the ANC, and it must be
calculated from the white blood cell count (WBC) and the percent of segmented and
band neutrophils (if the differential was performed on a machine, the percent neutrophils
will include both segmented and band neutrophils). If the laboratory report displays an
automated ANC value of exactly 0.5, the actual ANC value should be calculated from
the manual differential if available. The calculated value from the manual differential will
determine ANC recovery. If your institution’s laboratory reports do not display
the ANC value, use the following calculation to determine the ANC:

Traditionally, the definition of ANC recovery required selecting the first date of three consecutive days in which the
recipient’s ANC was ≥ 0.5×109/L (500/mm3). For various reasons it may not be possible to obtain daily laboratory values. Under
those circumstances, report ANC recovery based upon three consecutive laboratory values (drawn more than a day apart) as long
as the ANC remains ≥ 0.5×109/L (500/mm3).

Tracking the date of ANC recovery may not always be straightforward. In some cases
the ANC may fluctuate for a period of time before the recipient fully recovers. In other
cases the ANC may remain above 0.5 × 109/L for several days immediately postHCT and then fall below 0.5 ×109/L. Do not begin counting ANC values of ≥ 0.5 × 109/L
towards recovery until the ANC has dropped to the lowest level (nadir) post-HCT. If the
recipient was transplanted using a non-myeloablative (NST) or reduced intensity (RIC)
regimen, or was transplanted for an immunodeficiency (e.g., SCID, WAS), the
recipient’s ANC may never drop below 0.5 × 109/L. If this is the case, an ANC recovery
date will not be reported, and the “never below” option should be chosen. However, if
the recipient’s ANC drops below 0.5×109/L for even one day, this should be considered

If No if ANC ≥ 500/mm3 (or ≥ 0.5 × 109/L) was not achieved.
Check Not applicable if the recipient’s ANC never dropped below 0.5 × 109/L at
any time post-HCT. This option is only applicable in the 100-day reporting period.
Check Previously reported if this is the 6-month or annual follow-up, and the
initial ANC recovery has already been reported.

Question 5: Date ANC ≥ 500/mm3 (first of 3 lab values)
Enter the first date of the three consecutive laboratory values obtained on different days
where the ANC was ≥ 500/mm3 (or ≥ 0.5 × 109/L). For an example of
tracking ANC recovery, see the Tracking ANC Recovery example above.
For more information regarding reporting partial or unknown dates, see General
Instructions, General Guidelines for Completing Forms.
Question 6: Did secondary graft failure occur?
Secondary graft failure is defined when the recipient meets criteria for initial engraftment
but subsequently develops loss of a previously functioning graft by development of at
least two lines of cytopenia. Secondary graft failure is more often associated with
allogeneic HCT than with autologous HCT. Some possible causes for late graft failure
include graft rejection related to residual host immunity, persistent or progressive
disease, low donor cell yield, medication side-effect, infection or GvHD.2
If the recipient meets the criteria of graft failure, check Yes.

Initial Platelet Recovery
The Initial Platelet Recovery section can only be completed on the 100-day, 6-month, 1year, and 2-year follow-up forms. These questions will be skipped for all subsequent
reporting periods.
Combined Follow-Up
In scenarios where a cellular therapy was given after an HCT and this form is now being
completed based on the subsequent cellular therapy date, these questions do not apply
and are disabled.
The following questions refer to initial platelet recovery following the HCT for which this
form is being completed. All dates should reflect no platelet transfusions
administered for seven consecutive days. Report the date of the first of three
consecutive laboratory values ≥ 20 × 109/L obtained on different days, as shown in
the Reporting Platelet Recovery example below. Note that platelet recovery may take
place well after the recipient has returned to the referring physician for care. It is
essential that information and laboratory values be obtained from the referring
physician.
Transfusions temporarily increase blood cell counts. When the data is later used for
analysis, it is important to be able to distinguish between a recipient whose own body
was creating the cells and a recipient who required transfusions to support the counts.

• Select Yes if platelet count ≥ 20 × 109/ L was achieved and sustained for 3
consecutive laboratory values, obtained on different days without platelet
transfusions administered in the previous 7 days
• Select No if platelet count was not ≥ 20 × 109 / L or if platelet transfusions were

• Check Not applicable, if the recipient’s platelets never dropped below 20 × 109/L
at any time post-HCT and a platelet transfusion was never required. If the
recipient’s platelet count drops below 20 × 109/L and/or the recipient received a
platelet transfusion even once, do not use this option. This option is only
applicable in the 100-day reporting period.
• Check Previously reported if this is the six-month or annual follow-up, and initial

Reporting Estimated Dates
If a recipient is not seen within a month after their last platelet transfusion, an estimated
date may be reported. In this case, the date seven days after the last platelet
transfusion may be reported (see example A below). However, if the recipient is seen
within a month of the last platelet transfusion, an estimated date should not be reported.
Question 8: Date platelet ≥ 20 × 109/L
Enter the first date of three consecutive laboratory values obtained on different days
where the platelet count was ≥ 20 × 109/L. Ensure that no platelet transfusions were
administered for seven days immediately preceding this date. Include day seven, as
shown in the Reporting Platelet Recovery example above, when determining the
recovery date.
If three laboratory values were not obtained on consecutive days, but a sequential rise
of ≥ 20 × 109/L is demonstrated, follow the examples below when determining an
estimated date.
Reporting Scenarios
• Example 1: The recipient is being seen in the outpatient clinic and receives a
platelet transfusion on January 1. The platelet count is 22 × 109/L on January 2,
24 × 109/L on January 3, and 28 × 109/L on January 4. The recipient does not
come into the clinic for evaluation until one month later. The recipient has not
received any more platelet transfusions and the platelet count is well above 20 ×
109/L. Report January 8 (day seven post-platelet transfusion) for the date of
platelet recovery.
• Example 2: The recipient is being seen in the outpatient clinic and receives a
platelet transfusion on January 1. The platelet count is ≥ 20 × 109/L on January 2,
January 3, and January 4. The recipient is then discharged back to their primary
care physician. The transplant center receives a follow-up note from the primary

Question 11: Did acute GVHD persist?
Indicate if acute GVHD was clinically diagnosed in the previous reporting period and
persisted, with active symptoms, into the current reporting period.

Questions 12 – 18: Overall grade and organ staging of acute GVHD at diagnosis
These questions are intended to capture each organ stage and the overall grade at the
time of acute GVHD diagnosis. For reporting purposes, “at diagnosis” is defined as the
period between onset of signs / symptoms and the initiation of therapy to
treat GVHD (topical or systemic). The acute GVHD grading scale is based on clinical

evidence (physician observation), not histology. Pathology reports sometimes list a
histologic grade of GVHD. Do not report the histologic grade. GVHD scoring and
grading is based on clinical severity, not histological severity. Biopsy of affected organs
allows for more precise diagnosis as to the presence or absence of GVHD.
However, overall grading remains clinical and is based on the criteria published by
Przepiorka et al., Bone Marrow Transplant 1995; 15(6):825-8, see the GVHD Grading
and Staging table below.
Report the overall grade and organ staging at the diagnosis of acute GVHD. Review
the GVHD Reporting Instruction Overview for additional information and on the criteria
for each organ staging and grading.
Questions 19 – 26: Maximum overall grade of acute GVHD and maximum organ
stage of acute GVHD
These questions are intended to capture the maximum organ stage of each organ
involved in acute GVHD as well as the overall maximum grade of acute GVHD within
the reporting period. For detailed reporting instructions about reporting the maximum
grade and organ staging of acute GVHD, review the GVHD Reporting Instruction
Overview.
Question 27: Did chronic GVHD develop?
Indicate whether a new clinical diagnosis of chronic GVHD was documented during the
reporting period.
The Unknown option should only be used when there is no information about the
recipient’s GVHD status for the entire reporting period. This option should be used
sparingly and only when no judgement can be made about the presence or absence of
GVHD in the reporting period.
For detailed instructions on whether a new development of chronic GVHD should be
captured, review the GVHD Reporting Instruction Overview.
Question 28: Date of chronic GVHD diagnosis
Report the date of clinical diagnosis of chronic GVHD. The clinical diagnosis date may
not necessarily be the date the symptoms began (i.e., the recipient developed shortness
of breath one month prior to the clinical diagnosis of pulmonary chronic GVHD). If the
clinical diagnosis is documented, but the diagnosis date is unclear, obtain
documentation from the primary physician confirming the clinical diagnosis date.
If the recipient developed more than one episode of chronic GVHD in the same
reporting period, report the diagnosis date of the first episode of chronic GVHD.

Persistent GVHD and Day 100 Reporting Period
Previously, reporting Yes for Did chronic GVHD persist was not an applicable option for
the Day 100 reporting period. However, if there was a prior infusion, the recipient
developed chronic GVHD in the last reporting period of the previous
infusion and chronic GVHD persisted into the Day 100 reporting period of the current
infusion, report Yes, chronic GVHD persisted since the date of last report.
Question 29: Did chronic GVHD persist?
Indicate if chronic GVHD was clinically diagnosed in the previous reporting period and
persisted, with active symptoms, into the current reporting period. Do not report
quiescent or inactive chronic GVHD, or a prior history of GVHD. See instructions above
on reporting a chronic GVHD flare.
The Unknown option should only be used when there is no information about the
recipient’s GVHD status for the entire reporting period. This option should be used
sparingly and only when no judgement can be made about the presence or absence of
GVHD in the reporting period.
Review the GVHD Reporting Instruction Overview for various GVHD reporting
examples.
Question 30: Maximum grade of Chronic GVHD (according to best clinical
judgement)
Report the maximum chronic GVHD involvement, based on the opinion of the clinician
(i.e., clinical grade), since the date of the last report. The intent of this question is to
capture the maximum grade based on the best clinical judgment. If both the global
severity score and the score based on the clinician’s opinion is documented, report the
clinician score. If the maximum clinical grade is not documented, request documentation
from the recipient’s primary care provider.
Additional guidelines on reporting the maximum grade of chronic GVHD are outlined in
the GVHD Reporting Instruction Overview.
Question 31: Date of maximum grade of chronic GVHD
Report the date of maximum chronic GVHD involvement, based on clinical grade,
during the current reporting period. If the recipient had multiple instances in which
their GVHD reached the same maximum grade, report the earliest date.

Question 32 – 33: GVHD treatment
These questions are intended to capture if the recipient was still receiving systemic
steroids (steroid dose < 10 mg / day for adults, < 0.1 mg / kg / day for children,
excluding steroids for adrenal insufficiency) and non-steroid immunosuppressive agents
for GVHD on the contact date. Review the GVHD Reporting Instruction Overview for

Q34 – 36: Liver Toxicity Prophylaxis
Liver Toxicity Prophylaxis
Liver Toxicity Prophylaxis section can only be completed on the 100 day and 6-month
follow-up forms. These questions will be skipped for all subsequent reporting periods.
Question 34: Was specific therapy used to prevent liver toxicity?
Liver toxicities in transplant patients may be related to drugs / treatments,
infection, GVHD, iron overload, cirrhosis, or sinusoidal obstructive syndrome (SOS) /
veno-occlusive disease (VOD). Agents such as ursodiol may be given as prophylaxis
against one or more of these transplant-related liver injuries. Agents given to prevent
liver toxicity will generally be started prior to or during the conditioning regimen and may
be continued well after transplant.
Indicate whether the recipient received any therapy intended to prevent liver toxicity
during the current reporting period. For the Day 100 reporting period, this includes any
therapy given during the conditioning regimen. Report only agents given to prevent liver
toxicities, not those given to treat a diagnosed liver injury or toxicity.
Indicate if liver toxicity prophylaxis was given in the reporting period.

Syndrome (SOS)
VOD / SOS
VOD / SOS section can only be completed on the 100 day and 6-month follow-up forms.
These questions will be skipped for all subsequent reporting periods.
Veno-occlusive disease (VOD) / Sinusoidal obstruction syndrome (SOS) occurs
following injury to the hepatic venous endothelium, resulting in hepatic venous outflow
obstruction due to occlusion of the hepatic venules and sinusoids. This typically results
in a distinctive triad of clinical signs including hepatomegaly with right upper quadrant
tenderness, third space fluid retention (e.g., ascites), and jaundice with a cholestatic
picture. For more information on VOD / SOS including diagnostic criteria, refer to
the VOD / SOS .
Questions 37 – 38: Did veno-occlusive disease (VOD) / sinusoidal obstruction
syndrome (SOS) develop since the date of last report?
Indicate whether VOD / SOS was diagnosed during the reporting period. If Yes, report
the date of diagnosis.
If VOD/SOS was reported on the Post-TED (2450) Form, the Veno-occlusive Disease
(VOD) / Sinusoidal Obstruction Syndrome (SOS) (2553) Form must also be completed.

Q39: New Malignancy, Lymphoproliferative or Myeloproliferative
Disease / Disorder
Combined Follow-Up
In scenarios where a cellular therapy was given after an HCT and this form is now being
completed based on the subsequent cellular therapy date, these questions do not apply
and are disabled.
Question 39. Did a new malignancy, myeloproliferative, or lymphoproliferative
disease / disorder occur that is different from the disease / disorder for which
the HCT or cellular therapy was performed? (include clonal cytogenetic
abnormalities, and post-transplant lymphoproliferative disorders)
Indicate whether a new or secondary malignancy, lymphoproliferative disorder, or
myeloproliferative disorder has developed. Do not report recurrence, progression, or
transformation of the recipient’s primary disease (disease for which the transplant was
performed), or relapse of a prior malignancy.
New malignancies, lymphoproliferative disorders, or myeloproliferative disorders include
but are not limited to:
•
•
•
•
•

Skin cancers (basal, squamous, melanoma)
New leukemia
New myelodysplasia
Solid tumors
PTLD (post-transplant lymphoproliferative disorder) (report as NHL)

The following should not be reported as new malignancy:
•
•
•

Recurrence of primary disease (report as relapse or disease progression)
Relapse of malignancy from recipient’s pre-infusion medical history
Breast cancer found in other (i.e., opposite) breast (report as relapse)

•

Post-infusion cytogenetic abnormalities associated with the preinfusion diagnosis (report as relapse)
Transformation of MDS to AML post-infusion (report as disease progression)

Post-Transplant Lymphoproliferative Disorder (PTLD)
PTLD should be reported as a new malignancy if it was confirmed via a biopsy
(treatment not required) or suspected to be PTLD and treated.
Recurrent Skin Cancers
For most malignancies, do not report recurrence, progression or transformation of the
recipient’s primary disease (disease for which the infusion was performed) or relapse of
a prior malignancy in the “New Malignancy” section.
For example, a recipient was diagnosed with basal cell skin cancer on the neck four
months post-infusion and six months later had another basal cell located on the nose.
The lesion on the nose is not considered a metastasis from the neck, but a new discrete
lesion. These discrete episodes should be reported as a ‘new malignancy’ on the PostTED (2450) Forms.
If a new malignancy, lymphoproliferative disorder, or myeloproliferative disorder was
diagnosed during the reporting period, report Yes and complete the Subsequent
Neoplasms (3500) Form, which will come due.
The Previously reported option should only be used if the same malignancy has
already been reported on a Subsequent Neoplasms (3500) Form that was made do on
demand. See examples below. If it is unclear when to use this option,
contact CIBMTR Center Support if there are questions.
•

•

•

Example 1: A recipient developed a new malignancy at Day +68 and is reported
at the time the Day 100 Post-TED (2450) Form is completed. In this scenario,
report Yes, the recipient developed a new malignancy, and a Subsequent
Neoplasms (3500) form will be completed to report the new malignancy
information. For all future reporting periods, select No.
Example 2: A recipient developed a new malignancy during the seven-year
reporting period and the transplant center decided to create the Subsequent
Neoplasms (3500) form as an unscheduled form in FormsNet3SM to report the
new malignancy information immediately since a Post-TED (2450) Form for
seven-year reporting period will not come due. When the eight-year Post-TED
(2450) Form is completed, Previously reported, will be reported since a prior
Subsequent Neoplasms (3500) form has already been submitted for the new
malignancy.
Example 3: A recipient was diagnosed with basal cell skin cancer on the neck in
the one-year reporting period and two months later, within the same reporting
period, there was a diagnosis of basal cell located on the nose. The lesion on the
nose is not considered a metastasis from the neck, but a new discreet lesion.

Malignant Diseases Only
Only complete Disease Assessment at the Time of Best Response to Infusion questions
if the infusion being reported was given to treat a malignant disease. If the infusion
being reported was given to treat a non-malignant disease, leave these questions blank.
FormsNet3SM should enable / disable this section based on the primary disease
reported on the Disease Classification (2402) Form. Contact CIBMTR Customer
Support if it is believed FormsNet3SM is incorrectly enabling / disabling these fields.
Combined Follow-Up
In scenarios where both HCT and cellular therapy forms are being completed and a
disease specific form is being completed for the cellular therapy, disease assessment at
time of best response is not reported on this form and these questions are disabled. It
will be captured on the corresponding disease form.
This section collects the data known as “best response to transplant.” The purpose of
this section is to report the recipient’s best response to the planned course of
the HCT. This includes response to any therapy given for post-HCT maintenance or
consolidation and does not include response to treatment given for decreased / loss of
chimerism, measurable residual disease, persistent disease, or progressive / relapsed
disease.
If the recipient receives therapy for decreased / loss of chimerism, measurable residual
disease, persistent disease, or progressive / relapsed disease, the response to that
additional therapy should not be reported in this section. The best response prior to the
therapy should be reported. For subsequent reporting periods where the best response
prior to the start of unplanned therapy was reported, if a CR was achieved prior to
relapse / progression, the date of best response will be reported as Previously
reported. If a CR was not achieved prior to the administration of therapy, the best
response will be reported as Not evaluated. Refer to the best response to infusion
questions below for more information.
Reporting Complete Remission (CR) Post-HCT
Complete remission (CR) criteria vary by disease and are outlined in
the CIBMTR Forms Instructions Manual. Please refer to the appropriate disease
response criteria section of the Forms Instructions Manual and review the criteria to
report CR.
Tandem Transplants
For recipients receiving a tandem transplant, the best response to the prior infusion
(i.e., HCT #1 of the tandem) depends on the pre-infusion disease status.
•

If the recipient was in complete remission at the time of HCT #1, report the best
response to transplant as Continued complete remission (CCR).

•

If the recipient was not in complete remission at the time of HCT #1,
and no disease assessments (including labs and / or physician’s exams)
occurred in the reporting period, between HCT #1 and HCT #2 of their tandem
transplant, report Not evaluated. However, ensure the best response to infusion
and the current disease status are reported consistently
If the recipient was not in complete remission at the time of HCT #1, and
achieved complete remission prior to HCT #2 of their tandem transplant,
report Complete remission, the date which complete remission was achieved
If the recipient was not in complete remission at the time of HCT #1 and did not
achieve complete remission in response to HCT #1 and prior to HCT #2 of their
tandem transplant, report Not in complete remission (NCR)

Review the example below for additional information:
• Example 1: A recipient with neuroblastoma is not in complete remission prior to
transplant, in the 100-day reporting period the recipient receives a tandem
transplant. Between HCT 1 and HCT 2 the only disease assessment performed
was a clinical evaluation. In this case either option would be appropriate to
answer for the best response: Not evaluated or Not in complete remission
(NCR) and No disease detected but incomplete evaluation to establish CR.

Continued Complete Remission (CCR)
Continued Complete Remission (CCR) should be reported for all recipients who were
already in CR at the start of the preparative regimen.
Question 41: Compared to the disease status prior to the preparative regimen,
what was the best response to infusion? (Include response to any therapy given
for post-infusion maintenance or consolidation, but exclude any therapy given for
relapsed, persistent, or progressive disease)
Report the best response to infusion, using the following guidelines:
•
•
•
•

Continued complete remission (CCR): The recipient was already in CR at the
start of the preparative regimen.
Complete remission (CR): The recipient achieved CR post-infusion, excluding
unplanned therapy (i.e., therapy given for relapsed, persistent, progressive,
measurable residual disease, or decreased / loss of chimerism).
Not in complete remission: The recipient has not achieved a post-infusion CR.
Not evaluated: The not evaluated option should be used in two scenarios:
o The recipient’s disease was not evaluated post-infusion
▪ This should be rare as this would indicate no tests, radiological,
laboratory, or clinical assessment, was not performed at any time in
the reporting period.

o The recipient never achieved a post-infusion CR and started unplanned
therapy (including treatment given for decreased / loss of chimerism or
measurable residual disease), in a previous reporting period).
Question 42: Specify disease status if not in complete remission
For recipients Not in complete remission, indicate whether clinical evidence of
disease persisted on disease-specific assessments within the reporting period, using
the guidelines below:
•

•

No disease detected but incomplete evaluation to establish CR: The most
recent assessments have shown resolution of disease, not all assessments
required to report complete remission have been completed or the recipient has
not previously achieved a post-infusion Complete remission but does not have
any disease assessments performed within the reporting period.
Disease detected: The most recent radiological or clinical / hematological
assessment detects disease
o Persistence of abnormalities by molecular, cytogenetic, or flow cytometry
assessments does not constitute ‘disease detected’ and should not be
reported as disease detected for this question.

Review the examples below for additional information:
• Example 2: A recipient with multiple myeloma goes to transplant in VGPR,
without a bone marrow showing < 5% plasma cells completed prior to transplant.
Post-transplant serum and urine electrophoreses and immunofixations are
negative. However, no bone marrow biopsy is performed within the 100-day
reporting period. In this case, Not in complete remission should be selected for
the best response, and No disease detected but incomplete evaluation to
evaluation to establish CR for specifying the disease status if not in complete
remission data field.
• Example 3: A recipient with AML goes to transplant in Primary induction
failure. Post-transplant, they recover their blood counts, but had circulating
blasts noted on peripheral blood differential. They expire due to persistent
disease with their last CBC performed on their date of death showing circulating
blasts. In this case, Not in complete remission should be selected for the best
response to HCT, and Disease detected for specifying the disease status if not
in complete remission data field.
• Example 4: Similar to example 2, a recipient with AML goes to transplant in
Primary induction failure. They expire on D+11 due to infection and had not
engrafted as of that date. Their last CBC showed a WBC of 0.5 × 109/L with no
blasts detected on their differential. A bone marrow biopsy was not performed
between transplant and the date of death. In this case, Not in complete
remission should be selected for the best response to HCT, and No disease
detected by incomplete evaluation to establish CR for specifying the disease
status if not in complete remission data field.

Question 43: Was the date of best response previously reported?
Indicate whether complete remission was reported in a previous reporting period. This
question does not apply if the best response is Not in complete remission.
Question 44: Date of best response
Report the date complete remission was achieved. This date should fall after the
infusion date but before or on the date of contact for the current reporting period. This
should reflect the date of specimen collection or imaging for the latest assessment
required to fulfill the clinical / hematologic complete remission criteria for the recipient’s
primary disease for infusion.
Disease Assessment at Time of Best Response
The disease assessment questions (i.e., molecular, flow cytometry, cytogenetic,
radiologic and clinical / hematologic assessments) refer to disease assessments
performed at the time of best response (Date assessed). The following guidelines
should be used to determine whether testing was performed at the time of best
response:
•

•

If the recipient’s best response is Not in Complete Remission, report the latest
assessment performed during the reporting period. If the recipient never
achieved a CR and started treatment for decreased / loss of chimerism,
measurable residual disease, persistent disease, relapse, or progression, report
the most recent assessments prior to the start of therapy. Review examples 9
and 10 below.
If the recipient’s best response is Complete Remission, report testing performed
closest to the date of best response (Date assessed) and within the time
windows in the Disease Assessment Time Windows table.

period, the recipient achieves a Very good partial remission. FISH testing is only
performed on 2/1/2015, which is positive for the previously
detected IGH rearrangement. The 100-day date of contact is 4/15/2015. In this
case, report the recipient was Not in complete remission on the 100 Day PostTED (2450) Form and report FISH testing was performed on 2/1/2015. When the
best response is Not in complete remission report the most recent testing
performed during the reporting period (assuming treatment was not started for
decreased / loss of chimerism, measurable residual disease, persistent disease,
progressive / relapsed, disease during the reporting period – see example 6).
Example 6: A recipient receives a transplant on 1/1/2015 for multiple myeloma in
Partial remission. Prior to infusion, FISH testing detects an IGH rearrangement
associated with the recipient’s primary disease. During the 100-day reporting
period, the recipient has disease progression and starts treatment on
3/1/2015. FISH testing is performed on 2/1/2015 and 3/15/2015. Both tests are
positive for the previously detected IGH rearrangement. The 100-day date of
contact is 4/15/2015. In this case, report the recipient was Not in complete
remission on the 100 Day Post-TED (2450) Form and report FISH testing was
performed on 2/1/2015. When the best response is Not in complete remission
report the most recent testing performed during the reporting period and prior to
any unplanned therapy.
o Note: For all subsequent reporting periods, report Not evaluated for the
best response to infusion. If unplanned treatment was started in a prior
reporting period, the recipient’s best response to the infusion can no
longer be assessed.
Example 7: A recipient receives a transplant on 1/1/2015 for AML in Primary
induction failure. Prior to infusion, molecular testing confirms the recipient’s
disease is FLT3 positive. On 2/1/2015, the recipient achieves a morphologic
remission, but FLT3 is not tested at that time. Later, on 2/10/2015, molecular
testing is performed and confirms the recipient is FLT3 negative. In this case, the
report the recipient achieved a Complete remission on 2/1/2015 on the 100 Day
Post-TED (2450) Form and report molecular testing was performed at the time of
best response as testing was done within 15 days of 2/1/2015.
Example 8: A recipient receives a transplant on 1/1/2015 for AML in Primary
induction failure. Prior to infusion, molecular testing confirms the recipient’s
disease is FLT3 positive. On 2/1/2015, the recipient achieves a hematologic
remission, but FLT3 is not tested at that time. Later, on 3/1/2015, molecular
testing is performed and confirms the recipient is FLT3 negative. In this case, the
report the recipient achieved a Complete remission on 2/1/2015 on the 100 Day

disease. During the 100 Day reporting period, a PET / CT was performed on Day
60, confirming stable disease but then on Day 95, another PET / CT was
performed and showed progression. As a result, therapy for progression began
on Day 100. The best response to infusion for the Day 100 reporting period

would be reported as Not in complete remission – disease detected and
report Yes, radiologic assessments were performed with the Day 60 PET / CT,
as this is the most recent scan prior to disease progression.
Example 10: A recipient receives a transplant on 1/1/2020 for IgA Kappa Multiple
Myeloma in Stable disease. During the 100 Day reporting period, the first set of
myeloma labs on Day 29, 1/30/2020, show Progressive disease. Myeloma labs
repeated on Day 60 and Day 100 also showed disease progression. As a result,
therapy is planned to be given, starting in the 6-month reporting period, on Day
110. The best response to infusion for the Day 100 reporting period would be
reported as Not in complete remission – disease detected and report Yes,
clinical / hematologic assessments were performed with the Day 100 myeloma
labs, as this is the most recent testing in the reporting period. In cases where the
first assessment post-infusion shows progression, report the last assessment
prior to the start of treatment. If treatment doesn’t start until the next reporting
period, report the last assessment in the current reporting period.

Molecular Testing
The molecular testing questions are intended to capture molecular
abnormalities identified by molecular methods. Additional testing methods, such
as FISH, may identify molecular marker results but should not be reported in the
molecular section of the Post-TED (2450) Form. Abnormalities identified by
karyotyping, FISH, or microarray should only be reported in the cytogenetic section of
the Post-TED (2450) Form.
Question 45: Was the disease status assessed via molecular markers? (e.g. PCR,
NGS)
Molecular assessment involves determining whether a molecular marker for the disease
exists in the blood or bone marrow. Molecular assessment is the most sensitive method
of detection and can indicate known genetic abnormalities associated with the disease
for which the HCT was performed. Molecular assessments include polymerase chain
reaction (PCR) amplification to detect single specific disease markers; however,
molecular methods are evolving and now include Sanger sequencing and next
generation sequencing (e.g., Illumina, Roche 454, Proton / PGM, SOLiD). Molecular

applicable time window, report No.
Question 46: Date assessed
If the best response is Complete remission, report the date of testing performed
nearest to the date of best response (within the time windows listed in the Disease
Assessments Time Windows table above) and prior to any treatment for decreased /
loss of chimerism, measurable residual disease, persistent, progressive, or relapsed
disease, if applicable.
If the best response is Not in complete remission, report the date of the most recent
testing performed during the reporting period and prior to progression or treatment for
persistent disease, if applicable.
Report the date of specimen collection for molecular disease assessment. If exact date
is not known, refer to General Instructions, General Guidelines for Completing Forms for
information about reporting partial or unknown dates.
Question 47: Was disease detected?
Report whether the recipient’s primary disease was detected via assessment by
molecular marker. This question may be reported as Yes even when Not in complete
remission – no disease detected but incomplete evaluation to establish CR is
reported as the best response. In order to be considered positive for disease, the assay
must detect a number of copies of the molecular marker exceeding the threshold for
sensitivity of the assay, for a quantitative study. However, do note that presence of only
a single marker among numerous tested is sufficient to indicate disease detected.
Question 48: Was the disease status assessed via ClonoSEQ®?
ClonoSEQ® assessments measure minimal residual disease (MRD) at the molecular
level through proprietary bioinformatics and advancements in next-generation
sequencing (NGS). These assessments can be used to identify a recipint’s tumorassociated DNA sequences, predict long term outcomes, assess treatment response,
detect early relapse, inform changes to treatment, and monitor a recipient’s disease
burden over time.
If the recipient’s best response is Not in Complete Remission, report Yes if
assessments were performed, prior to any treatment for decreased / loss of chimerism,
measurable residual disease, persistent, progressive, or relapsed disease. Report No if
assessments were not performed prior to any unplanned therapy.

Question 50: Was disease detected?
Report whether the recipient’s primary disease was detected by ClonoSEQ® on the
date reported. This question may be reported as Yes even when Not in complete
remission – no disease detected but incomplete evaluation to establish CR is
reported as the best response.
Question 51: Was the disease status assessed via flow cytometry?
Flow cytometry is a technique that can be performed on blood, bone marrow, or tissue
preparations where cell surface markers can be quantified on cellular material. This
allows for the detection of abnormal cell populations for some diseases.
If the recipient’s best response is Not in Complete Remission, report Yes if
assessments were performed, prior to any treatment for decreased / loss of chimerism,
measurable residual disease, persistent, progressive, or relapsed disease. Report No if
assessments were not performed prior to any unplanned therapy.

Question 53: Was disease detected?
Report whether the recipient’s primary disease was detected by flow cytometry.
Report Yes if an abnormal cell population associated with the recipient’s primary
disease was detected regardless of the sensitivity of the flow cytometry panel
performed; this means an abnormal cell population detected by MRD flow cytometry
would be reported in the same way as an abnormal cell population detected by a
standard flow cytometry assay. This question may be reported Yes even when Not in
complete remission – no disease detected but incomplete evaluation to establish
CR is reported as the best response.
Question 54: Was the disease status assessed by cytogenetic testing?
(karyotyping or FISH)
Cytogenetic studies involve the study of chromosomes, typically through one of two
methods: karyotyping or fluorescence in situ hybridization (FISH). Blood, bone marrow,
or tissue preparations may be tested by either of these two methods. Karyotyping is
both less sensitive and less specific than FISH testing; FISH studies identify only
abnormalities detectable by the employed probe set and cannot provide information
about the presence or absence of chromosomal abnormalities or markers outside the
specific probe set utilized.
If the recipient’s best response is Not in Complete Remission, report Yes if
assessments were performed, prior to any treatment for decreased / loss of chimerism,
measurable residual disease, persistent, progressive, or relapsed disease. Report No if

Question 55: Was the disease status assessed via FISH?
FISH XX/XY probe sets are not considered relevant to disease assessment and should
not be reported in the disease assessment section. Chromosomal microarrays /
chromosomal genomic arrays should be reported as FISH assessments.
If the recipient’s best response is Not in Complete Remission, report Yes if

Question 60: Was disease detected
Report whether the recipient’s primary disease was detected by karyotyping on the date
reported. Do not include clinically insignificant polymorphism, or chromosomal
abnormalities of no known significance, as disease detected; this includes anomalies
such as age-dependent loss of the chromosome Y. This question may be reported
as Yes even when Not in complete remission – no disease detected but
incomplete evaluation to establish CR is reported as the best response.
Question 61: Was the disease status assessed by radiological assessment?
(e.g. PET, MRI, CT)
Radiologic assessments are imaging techniques used to assess disease response to
transplant, typically for lymphomas or solid tumors, though valuable in some less
common presentations of disease, such as leukemia cutis. Imaging techniques used to
evaluate disease response typically include PET, CT, or MIBG, but may include x-ray,
skeletal survey, or ultrasound in some cases.

assessments (including labs and physician’s exams) were not performed at the time of
best response.
Question 64: Was the disease status assessed by clinical / hematologic
assessment?
Clinical / hematologic disease assessments are the least sensitive method of disease
detection. Examples include circulating blasts in the bloodstream for AML, and
enlargement of a malignant mass for lymphoma or a solid tumor on physical
examination. Every recipient who has an evaluation by a physician has a “clinical”
assessment. Do not include radiologic or imaging assessments when answering this
question.
If the recipient’s best response is Not in Complete Remission, report Yes If
assessments were performed prior to any treatment for decreased / loss of chimerism,
measurable residual disease, persistent, progressive, or relapsed disease. Report No If
assessments were not performed prior to any unplanned therapy.
If the recipient’ best response is Complete Remission, report Yes if disease
assessments were performed within the time windows in the Disease Assessment Time
Windows table above. If testing was not performed within the applicable time window,
report No.
Question 65: Date assessed
If the best response is Complete remission, report the date of the assessment
performed nearest the date of best response (within the time windows listed in
the Disease Assessments Time Windows table above) and prior to any treatment for
decreased / loss of chimerism, measurable residual disease, persistent, progressive, or
relapsed disease. This will likely match the date CR reported in Date assessed for the
best response, since complete remission criteria generally require clinical or
hematologic assessment to confirm.
If the best response is Not in complete remission – no disease detected but
incomplete evaluation to establish CR, report the last assessment performed in the
reporting period and prior to any treatment for decreased / loss of chimerism,
measurable residual disease, persistent, progressive, or relapsed disease.
If the best response is Not in complete remission – disease detected, report the
most recent assessment performed in the reporting period that detects disease and
prior to any treatment for decreased / loss of chimerism, measurable residual disease,
persistent, progressive, or relapsed disease, if applicable. If disease was not detected
by this method report the date of the most recent assessment performed and prior to
any treatment for decreased / loss of chimerism, measurable residual disease,
persistent, progressive, or relapsed disease, if applicable.

reporting period
If the first relapse or progression (by any method) occurred in a previous reporting
period, select Previously reported.
See below for definitions and examples of each method of detection:
•

•

•

•

•

Molecular: Molecular assessment involves determining whether a molecular
marker for the disease exists in the blood or bone marrow. Molecular
assessment is the most sensitive method of detection and can indicate known
genetic abnormalities associated with the disease for which the HCT was
performed. Molecular assessments include polymerase chain reaction (PCR)
amplification to detect single specific disease markers, Sanger sequencing, and
next generation sequencing. This option should also be selected if the recipient
relapsed / progressed by ClonoSEQ®.
Flow cytometry: Flow cytometry is a technique that can be performed on blood,
marrow, or tissue preparations where the cell surface markers can be quantified
on cellular material. This allows for the detection of abnormal cell populations for
some diseases. Flow cytometry may also be referred to as immunophenotyping.
Cytogenetic: Cytogenetic studies involve the study of chromosomes, typically
through one of two methods: karyotyping or fluorescence in situ hybridization
(FISH). Blood, bone marrow, or tissue preparations may be tested by either of
these two methods. Karyotyping is both less sensitive and less specific
than FISH testing; FISH studies identify only abnormalities detectable by the
employed probe set and cannot provide information about the presence or
absence of chromosomal abnormalities or markers outside the specific probe set
utilized.
Radiologic (e.g., PET, MRI, CT): Radiologic assessments are imaging
techniques used to assess disease response. Imaging techniques used to
evaluate disease response typically include PET, CT, or MIBG, but may include
x-ray, skeletal survey, or ultrasound in some cases.
Clinical / hematologic: Clinical / hematologic assessment is the least sensitive
method of disease detection. Examples include circulating blasts in the
bloodstream for AML, or enlargement of a malignant mass for lymphoma or a
solid tumor. Every recipient who has an evaluation by a physician has a “clinical”
assessment. Examples of clinical/hematologic assessments include bone
marrow biopsy / morphologic evaluation, complete blood count, serum protein
electrophoresis, etc.

reporting period. Select all the indications. See below for definitions of each indication. If
the intent of the therapy is unclear, seek physician clarification.
•
•
•
•
•

Decreased / loss of chimerism: Chimerism is the percentage of donor immune
cells in a recipient compared to the percentage of recipient immune system cells.
Treatment may be given for decreasing chimerism to prevent relapsed disease.
Measurable Residual Disease: Recipient is in hematologic CR but has
evidence of disease by more sensitive assessments including molecular, flow
cytometry or cytogenetic methods.
Persistent Disease: The recipient was in primary induction failure or relapse at
the time of infusion and has not achieved a hematologic CR post-infusion.
Progressive Disease: The recipient has not achieved a complete remission and
has worsening disease burden.
Relapsed Disease: The recipient was in CR at the time of infusion, or the
recipient achieved a CR post-infusion. In either case, treatment is administered
for a relapse which occurred post-infusion.

See the Intervention reporting scenarios provided below for further clarification.
Question 79: Specify the method(s) of detection for which intervention was given
(check all that apply)
Indicate the methods detecting the reason for which therapy for decreased / loss of
chimerism, measurable residual disease, persistent disease, progressive disease, or
relapsed disease was administered (as reported above). Indicate all methods of
detection; given that the assessment was performed prior to the start of the
intervention(s) and was consistent with the rationale reported above. There may be
scenarios for which an assessment by a particular method was last performed in the
prior reporting period but was still consistent with the justification reported; in this case,
the method of disease assessment should be reported.
If multiple therapies were given during the reporting period for different reasons (i.e., the
recipient initially receives treatment for persistent disease and subsequently receives
different treatment for progressive disease during the same reporting period), select any
methods of detection confirming the reason above. See the Intervention reporting
scenarios provided below for further clarification.
If assessment by that method was not performed or was performed and not consistent
with the reason for which intervention was given reported above, do not report the
disease assessment.

Intervention Reporting Scenarios
•

•

Example 1: A recipient with NHL in CR at the time of infusion has a relapse
during the 100 day reporting period. Relapse was detected by a PET scan and a
lymph node biopsy. Following these assessments, Rituximab was started on
5/1/2016. The disease did not respond to this therapy prompting a switch to
Brentuximab on 6/1/2016. The 100 Day date of contact is 6/15/2016.
o 100 Day Post-TED Form
▪ Was intervention given for decreased / loss of chimerism,
measurable residual disease, persistent disease, or progressive /
relapsed disease: Report Yes to indicate therapy was given for
relapsed disease during this reporting period.
▪ Specify reason for which intervention was given: Report Relapsed
disease.
▪ Specify the method(s) of detection for which intervention was given:
Check the boxes to indicate that disease was detected by both
Clinical / hematologic (lymph node biopsy) and Radiological
(PET scan) assessments.
▪ Date intervention started: Report 5/1/2016 to reflect the date of the
first treatment given for relapsed disease.
▪ Specify systemic therapy: Report both Rituximab and
Brentuximab as treatments for relapsed disease given during the
reporting period.
Example 2: A recipient with multiple myeloma in VGPR at the time
of infusion was started on maintenance Lenalidomide during the six-month
reporting period. Later in the reporting period, progression was detected by
serum protein electrophoresis on 9/15/2014 and so the recipient stopped
lenalidomide and started bortezomib as well as dexamethasone on 9/20/2014.
The recipient continued bortezomib and dexamethasone treatment into the oneyear reporting period.
o Six Month Post-TED Form
▪ Was intervention given for decreased / loss of chimerism,
measurable residual disease, persistent disease, or progressive /
relapsed disease: Report Yes to indicate therapy was given for
progressive disease during this reporting period.

•

Specify reason for which intervention was given: Report
Progressive disease.
▪ Specify the method(s) of detection for which intervention was given:
Check the box to indicate that disease was detected by Clinical /
hematologic (serum protein electrophoresis) assessment.
▪ Date intervention started: Report 9/20/2014 to reflect the date of the
first treatment given for progressive disease.
▪ Specify systemic therapy: Report Bortezomib as treatment for
progressive disease given during the reporting period.
Dexamethasone is no longer captured on the Post-TED (2450)
Form. The lenalidomide therapy should not be reported in this
section of the form. This medication was given as maintenance
therapy and will therefore be reported under Post-Infusion
Treatment Given to Prevent Relapse or Progression
o One Year Post-TED Form
▪ Was intervention given for decreased / loss of chimerism,
measurable residual disease, persistent disease, or progressive /
relapsed disease questions: These questions will be disabled in
FormsNet3SM. Starting with Revision 5 of the Post-TED (2450)
Form, therapy given for relapsed or progressive disease will only be
captured in the reporting period in which treatment first started.
Example 3: A recipient with multiple myeloma in PR at the time of infusion was
started on lenalidomide during 100-day reporting period (started 3/15/2012) due
to persistent disease (detected by serum electrophoresis testing). This treatment
was not planned and was given due to an unsatisfactory disease response
to HCT. Thirty days after lenalidomide started, a karyotype assessment
confirmed persistent cytogenetic abnormalities present in a bone marrow sample.
Lenalidomide was continued into the six-month reporting period, during which,
there was disease progression (detected by serum electrophoresis).
Lenalidomide was stopped and carfilzomib was started on 5/30/2012. By the end
of the six-month reporting period, the recipient achieved complete remission in

withdrawal is defined as any decrease in immunosuppression to promote graft
versus leukemia effect.
Blinded randomized trial: A blinded, randomized trial refers to a research
treatment protocol in which the participant is assigned to the control arm or
investigational group, and the researcher or clinician is not informed whether the
subject is receiving the placebo or standard of care versus the investigational
therapy. This makes it impossible to report agents or therapies the recipient is
receiving.
Intrathecal therapy: Intrathecal therapy is chemotherapy administered to the
CNS via a lumbar puncture. It may be given to treat or prevent leukemic blasts in
the cerebrospinal fluid or other CNS tissues.
Radiation: Radiation therapy uses high-energy radiation to kill cancer cells.
External beam radiation is one of the more frequently used types of radiation. In
this method, a beam of radiation is delivered to a specific part of the body, such
as the mediastinum. Radiation may be planned if bulky disease was present just
prior to transplant for a recipient with lymphoma or a solid tumor.
Systemic therapy: refers to a delivery mechanism where a therapeutic agent is
delivered orally or intravenously, enters the bloodstream, and is distributed
throughout the body.
Other intervention: Indicate whether the recipient received additional therapy for
decreased / loss of chimerism, measurable residual disease, persistent disease,
progressive / relapsed disease which does not fit into the previous categories
(i.e. surgery). Specify the other intervention given. Do not report a subsequent
infusion (i.e. DLI, cellular therapy, subsequent HCT) in this field if one was given.
All subsequent infusions will be captured at the top of this form and do not need
to be re-reported.

Steroids Administered Post-Infusion
Previously, steroids given for relapsed, persistent, or progressive disease were reported
as Other systemic therapy. Steroids (e.g. dexamethasone) are no longer captured on
the Post-TED (2450) Form and they should not be reported.
Questions 82 – 84: Specify systemic therapy (check all that apply)
Systemic therapy agents and treatment regimens vary based on disease, prognosis,
and protocol. Treatment may consistent of one or multiple drugs and may be given in an
inpatient or outpatient setting; additionally, drugs may be administered on a single day,
over consecutive days, or continuously.
Indicate which systemic therapy agents were administered during the current reporting
period for relapse, persistent, or progressive disease. If the recipient received a
chemotherapy agent that is not listed (i.e., cyclophosphamide), Chemotherapy should
be selected. If the recipient received a therapeutic agent, other than chemotherapy, that
is not listed, select Other systemic therapy and specify the systemic therapy.

Malignant Diseases Only
Only complete the Current Disease Status section if the infusion being reported was
given to treat a malignant disease. If the infusion being reported was given to treat a
non-malignant disease, leave these questions blank. FormsNet3SM should enable /
disable this section based on the primary disease reported on the Disease Classification

disease specific form is being completed for the cellular therapy, current disease status
is not reported on this form and these questions are disabled. It will be captured on the
corresponding disease form.
Tandem Transplants
For recipients receiving a tandem transplant, the current disease status prior to HCT #2
of the tandem depends on the pre-transplant disease status and the best response to
the prior transplant (i.e., HCT #1 of the tandem).
• If the recipient was in complete remission at the time of HCT #1 or achieved
complete remission prior to HCT #2 of their tandem transplant, the current
disease status should be reported as Complete remission (CR) (given there is
no evidence of relapse / progression disease based on labs / clinical
assessments between the tandem HCTs).

•

If the recipient was not in complete remission or did not achieve complete
remission in response to HCT #1 prior to HCT #2 of their tandem transplant,
either Not in complete remission (NCR) or Not evaluated would be
appropriate options; however, ensure the best response to infusion and the
current diseases status are answered consistently

Question 96: What is the current disease status?
Indicate the disease status of the primary transplant disease as of the last evaluation in
the reporting period. Complete remission (CR) criteria vary by disease and are outlined
in the CIBMTR Forms Instructions Manual.
Use the following guidelines when reporting the current disease status:
•
•
•

Complete remission (CR): The recipient achieves CR or continues in CR at the
time of last evaluation in the reporting period,
Not in complete remission: The recipient is not in CR due to presence of
disease on last evaluation in the reporting period or an incomplete evaluation that
does not allow for reporting CR
Not evaluated: The recipient’s disease status was not evaluated post-infusion.
This option is not commonly used, as this would indicate that no
tests (radiological, laboratory, or clinical assessment) were performed to assess
the CR status at any time during the reporting period.

The center does not need to repeat all disease-specific assessments (biopsies, scans,
labs) each reporting period in order to complete current disease status data fields. Once
a particular disease status is achieved, the center can continue reporting that disease
status (based on labs / clinical assessments) until there is evidence of relapse /
progression.
▪

▪

Example 1: A recipient with neuroblastoma is not in complete remission prior to
transplant, in the 100-day reporting period the recipient receives a tandem
transplant. Between HCT 1 and HCT 2 the only disease assessment performed
was a clinical evaluation. In this case either option would be appropriate to
answer for the current disease status: Not evaluated or Not in complete
remission (NCR) and No disease detected but incomplete evaluation to
establish CR. However, ensure the best response and the current disease
status are consistent.
Example 2: A recipient with neuroblastoma is in complete remission prior to
transplant, in the 100-day reporting period the recipient receives a tandem
transplant. Between HCT 1 and HCT 2 the only disease assessment performed
was a clinical evaluation in which the clinician did not mention progressive or
relapsed disease. In this case Complete remission (CR) should be reported for
the current disease status.

Question 97: Specify disease status if not in complete remission
Disease status criteria are generally based upon clinical assessment confirming
ongoing presence or absence of disease. However, there are also situations in which an
evaluation may have been performed but be incomplete and not have all testing
required in order to meet the criteria for reporting complete remission (CR).
For recipients Not in complete remission, indicate whether clinical evidence of
disease persisted on disease-specific assessments within the reporting period. Review
the guidelines below:
•

•

No disease detected but incomplete evaluation to establish CR: All
assessments have shown resolution of disease, but not all assessments required
to report complete remission have been completed. This option is also
appropriate for scenarios in which the recipient has not previously achieved a
post-infusion CR and the only assessment completed in the reporting period was
a physician’s evaluation.
Disease detected: Disease persists by radiological or clinical / hematologic
assessments. Persistence of abnormalities by molecular, cytogenetic, or flow
cytometry assessments does not constitute “disease detected.”

Review the examples below for additional information:
▪

▪

▪

Example 3: A recipient with multiple myeloma goes to transplant in VGPR,
without a bone marrow showing < 5% blasts completed prior to transplant. Postinfusion serum and urine electrophoreses and immunofixations are negative.
However, no bone marrow biopsy is performed within the 100-day reporting
period. Report the status as Not in complete remission – No disease detected
but incomplete evaluation to establish CR.
Example 4: A recipient with AML goes to transplant in primary induction failure.
Post-infusion, the recipient’s counts recover, but had circulating blasts noted on
differential. The recipient expired due to persistent disease with their
last CBC performed on their date of death showing circulating blasts. Report the
status as Not in complete remission – Disease Detected.
Example 5: Similar to example 4, a recipient with AML goes to transplant in
primary induction failure. The recipient expired on D+11 due to infection and had
not engrafted as of that date. Their last CBC showed a WBC of 0.5 × 109/L with
no blasts detected on their differential. A bone marrow biopsy was not performed
between transplant and the date of death. Report the status as Not in complete
remission - No disease detected by incomplete evaluation to establish CR.

Question 98: Date of assessment of current disease status
Report the date of latest clinical / hematologic assessment for the current disease status
using the guidelines below:

DRAFT Post-TED
CIBMTR Form 2450

Report the date of the clinical / hematologic assessment using the guidelines below:
•

•

•

•

If the current disease status is Complete remission, report the date of the most
disease specific clinical / hematologic or radiologic assessment performed within
approximately 30 days of the contact date.
If the current disease status is Not in complete remission – disease detected,
report the most recent clinical / hematologic or radiologic assessment performed
in the reporting period that detects disease.
If the current disease status is Not in complete remission – no disease
detected but incomplete evaluation to establish CR, report the last clinical /
hematologic or radiologic assessment performed in the reporting period.
If there are no disease-specific assessments within the reporting period, report
the latest assessment in which the recipient was clinically assessed by a
physician or midlevel clinician. In this scenario, this date does not need to be
consistent with the disease status reported current disease status.

Refer to General Instructions, General Guidelines for Completing Forms, for information
about reporting partial or unknown dates.

▪

Example 6: The current disease status for a recipient with non-Hodgkin’s
lymphoma is Complete remission. A PET scan was performed 3 months prior to
the contact date showing no evidence of disease and a physician’s exam was
performed on the contact date. In this case, the physician’s exam performed on
the contact date should be reported as the current disease assessment date
since this is the most disease specific clinical / hematologic assessment
performed within 30 days of the contact date.
Example 7: For a recipient with neuroblastoma, the current disease status is Not
in complete remission – disease detected since disease was still present on
the last PET scan. The PET scan was performed 7 months prior to the contact
date and a physician’s exam was performed on the contact date – disease
cannot be detected by the physician’s exam. The date of the PET scan should be
reported as the current disease assessment date since this is the most disease
specific clinical / hematologic assessment showing evidence of disease.
Example 8: The bone marrow biopsy performed for a recipient with AML still
showed > 5% blasts in the bone marrow and therefore, the current disease status
is reported as Not in complete remission – disease detected. The bone
marrow biopsy was performed 6 months prior to the contact date and a CBC was
performed 2 weeks prior to the contact date – the CBC showed > 5% blasts in
the blood. In this scenario, the current disease assessment date should be
reported as the date of the CBC as this is the most recent disease specific
clinical / hematologic assessment showing evidence of disease.

performed two weeks prior to the contact date which showed < 5% plasma cells;
however, the last set of myeloma labs performed in the prior reporting period still

Q1 – 4: Chimerism Studies
Chimerism studies are performed to determine the percentage of blood or marrow cells
post-infusion produced from donor hematopoietic stem cells and the percentage
produced from host (recipient) hematopoietic stem cells.
Appendix C: Cytogenetics
Refer to Chimerism and Cytogenetics found in Appendix C: Cytogenetics for additional
information.
Different types of blood cells and a variety of laboratory tests can be used to determine
if a chimera (presence of both donor- and host-derived cells) exists. If cytogenetic
testing was performed to look for disease markers, and the donor and recipient are of
different sexes, the test may also be used to determine if a chimera exists. If the donor
and recipient are of the same sex, cytogenetic testing using the common staining
technique, known as giemsa banding (G-banding), cannot be used to determine if there
is a chimera. However, quinicrine banding (Q-banding) can be used to identify if the
cells are of donor origin or not in a same-sex transplant, as this staining technique
highlights inherited chromosome polymorphisms on certain human chromosomes
including 3, 4, 13, 15, 21, 22, and Y. This is not a commonly used staining technique
and is only helpful when the polymorphism is documented pre-infusion.
Failed Chimerism Studies
If chimerism studies were attempted, but no evaluable results were obtained, do not
report the test.

Transplant centers may perform frequent chimerism studies. If there is a need to reduce
the number of chimerism study results reported due to volume, ensure that the following
are reported at a minimum:
•
•
•

Studies performed on or at approximately Day 30
Most recent studies performed prior to or on the date of contact for the Day 100,
Day 180, and Day 365 timepoints
Most recent studies performed prior to and after an intervention (such as a donor
cellular infusion)

Questions 2 – 3: Cells tested (check all that apply)

CIBMTR Form 2199

Instructions for Donor Cellular Infusion (2199)
This section of the CIBMTR Forms Instruction Manual is intended to be a resource for completing the Donor Cellular
Infusion.

Donor Cellular Infusion
This Donor Cellular Infusion is a single abbreviated form with elements of the Pre-CTED (4000), Cell Therapy Product
(4003), Cell Therapy Infusion (4006), and Post-CTED (4100), which must be completed for all recipients who receive a
donor lymphocyte infusion (DLI).
DCIs are defined as:
• The infusion must be post-allogeneic HCT and probably from the same donor*
• Product must be lymphocytes only
• Product cannot be genetically modified
*This is the most common scenario right now, but in the future, DCI products may be obtained from a different donor

WBC: The white blood cell count is a value that represents all the white blood cells in the blood. If the count is
too high or too low, the ability to fight infection may be impaired. If the WBC was assessed on the reported
CBC date, report the value and units of measurement.
Neutrophils: Neutrophils are a subtype of white blood cell that fights infection. The value on the laboratory
report may be a percentage or an absolute value. If an absolute value is reported, divide it by the white blood
cell count for a percentage. Neutrophils are also known as polymorphonuclear leukocytes (PMNs). If
neutrophils were assessed on the reported CBC date, report the percentage.
Lymphocytes: Lymphocytes are another subtype of white blood cell that fights infection. The value on the
laboratory report may be a percentage of an absolute value. If an absolute value is reported, divide it by the
white blood cell count for a percentage. If lymphocytes were assessed on the reported CBC date, report the
percentage.
Hemoglobin: Hemoglobin is a molecule in red blood cells that delivers oxygen to tissues throughout the body.
A low hemoglobin count value is considered “anemia” and blood transfusions, or growth factors may be
required to increase the hemoglobin level. If the hemoglobin was assessed on the reported CBC date, report
the value and units of measurement.
Hematocrit: The hematocrit is the percentage (sometimes displayed as a proportion) of red blood cells
relative to the total blood volume. Low hematocrit may require red blood cell transfusions or growth factors.
Indicate if the recipient received a red blood cell transfusion within 30 days prior to sample draw date. If
hematocrit were assessed on the reported CBC date, report the percentage. Additionally, indicate if the
recipient received red blood cell transfusion(s) within 30 days prior to the date of the CBC reported above.
Platelets: Platelets are formed elements within the blood that help with coagulation. A low platelet count,
called thrombocytopenia, may lead to easy bleeding or bruising. Thrombocytopenia may require platelet
transfusions. If platelets were assessed on the reported CBC date, report the value and units of
measurement. Additionally, indicate if the recipient received platelet transfusion(s) within seven days prior to
the date of the CBC reported above.

Performance Scores
Refer to Appendix L: Karnofsky / Lansky Performance Status for more information on reporting performance scores.
Question 19: What scale was used to determine the recipient’s functional status prior to the donor cellular
infusion?

CIBMTR Forms Manual: Donor Cellular Infusion DRAFT
Version 2 Revision 2
Page 5 of 11

DRAFT Donor Cellular Infusion
CIBMTR Form 2199

The CIBMTR uses the Karnofsky / Lansky scale to determine the functional status of the recipient immediately prior
to the start of lympho-depleting therapy / systemic therapy or infusion. The Karnofsky Scale is designed for
recipients aged 16 years and older and is not appropriate for children under the age of 16. The Lansky Scale is
designed for recipients one year old to less than 16 years old.
Report the scale used to determine the recipient’s functional status prior to the start of lympho-depleting therapy /
systemic therapy or infusion.
For recipients less than one year old, the Performance score questions should be left blank.
Questions 20 – 21: Performance score
Report the recipient’s performance status immediately prior to the start of lympho-depleting therapy / systemic
therapy or infusion. For the purposes of this manual, the term “immediately prior” represents the pre-infusion workup phase, or approximately one month prior to the start of the lympho-depleting therapy or systemic therapy.
If a Karnofsky / Lansky score is not documented in the source documentation (e.g., inpatient progress note,
physician’s clinic note), data management professionals should not assign a performance score based on analysis
of available documents. Rather, a physician or mid-level health care provider (NPs and PAs) should provide
documentation of the performance score. Documentation from an RN who has been trained and authorized to
determine performance scores may also be used.
If only an ECOG is documented, convert the ECGO score to Karnofsky / Lansky. Refer to Appendix L: Karnofsky /
Lansky Performance Status and / or the memorandum and worksheet example found in ‘Appendix L’ of the
‘Appendices’ section located in the Retired Forms Manuals webpage.
Questions 22 – 23: Date of cell product collection
Indicate if the date of cell product collection is Known. If Known, report the date. If the cell product is collected over
multiple days, report the first date when collection began.

If the exact date is not known, refer to General Instructions, General Guidelines for Completing Forms for more
information regarding reporting partial or unknown dates.
Question 24: Was the product previously cryopreserved?
DCI products may be leftover products from a prior HCT. Indicate if the DCI product was previously cryopreserved.
Questions 25 – 26: Tissue Source
Select from the list the tissue source(s) of the cellular product for this infusion. If the source is selected as Other
tissue source, specify the other source.
The tissue source for non-mobilized peripheral blood, peripheral blood apheresis, and MNCs should be reported
as Peripheral blood.
DCIs and Genetic Modification
DCIs are not genetically modified by CIBMTR definition. Any product that is genetically modified must be reported on
a Pre-CTED (4000) as a cellular therapy, not a DCI, and requires 15 years of follow-up. Contact CIBMTR Center
Support if corrections are required.
Question 27: Were the cells in the infused product selected / modified / engineered / manipulated prior to
infusion?
Indicate if the cells in DCI were product selected (i.e., selective retention of a population of desired cells through
recognition of specified characteristics), modified, engineered and / or manipulated prior to infusion.
Steps in Manipulation
If the manipulation consists of several steps, individual steps do not need to be reported as separate manipulations. For
example, T-cell depletion that is part of expansion, does not need to be reported.
Cryopreservation as a Manipulation
Do not report cryopreservation (including plasma removal as part of cryopreservation) as a method of manipulation.

Specify the method(s) of manipulation. Check all that apply.
•
•

•
•
•

Cultured (ex-vivo expansion): cells placed in culture to increase in number (i.e., to expand) allowing for sufficient
cells for infusion.
Induced cell differentiation: cells placed in culture to give rise to cellular elements with biological characteristics
other than those of the cells being cultured (i.e., mesenchymal stromal cells cultured to make osteoblasts;
pluripotent stem cells cultured to make neural cell precursors). Usually, the description of the process would
include the term “differentiation of cells X into cells Y”. This scenario can be seen in regenerative medicine
indications.
Cell selection – positive: the manipulation of a cellular therapy product such that a specific cell population(s) is
enriched. This may be achieved by using an antibody that binds to a specific population of cells (e.g., CD4+
selection).
Cell selection – negative: the manipulation of a cellular therapy product such that a specific cell population(s) is
reduced.
Cell selection based on affinity to a specific antigen: the cellular product undergoes selection to isolate the
target population based on the ability of the target population to bind or recognize a specific antigen (e.g., a T cell
population recognizing viral proteins, or a protein associated with cancer).

Select Other cell manipulation if the manipulation is listed above and specify the other manipulation.
Product Analysis
This form captures infusions of lymphocytes only. If this was an infusion of another cell type, it must be reported on a PreCTED (4000) as a cellular therapy, not a DLI. Please contact CIBMTR Center Support if corrections are needed.
Product Infusion
The cell type(s) administered should be for a single DCI. If multiple DCIs were given in the reporting period, each DCI
should be reported on a separate Donor Cellular Infusion (2199).

DRAFT Recipient Death
CIBMTR Form 2900

Instructions for Recipient Death (2900) Form
This section of the CIBMTR Forms Instruction Manual is intended to be a resource for
completing the Recipient Death Form.

Recipient Death (2900)
The Recipient Death Data (2900) captures cause of death data fields for all recipients.
The leading cause of post-infusion mortality is persistent, recurrent, or relapsed primary
disease. Other common causes of death include graft-versus-host disease, infection,
and organ failure. As hematopoietic cell transplant and cellular therapy evolves,
reporting accurate cause of death data is important to investigating the variables that
are associated with post-infusion outcomes.
If Dead is reported as the current survival status at the date of last contact on the PostTED (2450), Post-Infusion Follow-Up (2100) or Cellular Therapy Essential Data FollowUp (4100) form at the 100-day, six month, and yearly time points, complete the
Recipient Death Data (2900) as soon as possible after the recipient has died.
Autologous Recipients with No Consent for Research Database
Do not complete the Recipient Death (2900) Form for Autologous recipients who did not
consent to be part of the research database.
Lost to Follow-Up
Occasionally, centers may lose contact with recipients for a variety of reasons, including
the recipient’s moving, changing physicians, or death. After attempts to contact the
recipient or referring physician have failed, the recipient may be declared lost to followup. If your center later receives documentation that a recipient is dead, report this on the
appropriate follow-up form for the time period in which the recipient died. This may
require resetting a form that was previously made Lost to Follow Up (LTF) or Survival
(SUR). This may happen when a center becomes aware of the death after it has
reported that the recipient is lost to follow-up. To reset the form, click the blue
counterclockwise arrow icon.

6 of the Form 2900.

Cause of Death Options
Review the following guidelines when reporting the primary and contributing cause of
deaths.
Sepsis and Septic Shock
Sepsis and septic shock should not be reported as Other cause, as the true cause of
death is an infection. Review the infection section below for additional details.
Post-Transplant Lymphoproliferative Disorder (PTLD)
If PTLD is listed as a cause of death, report the cause of death as a New malignancy
(post-infusion).
Recurrence / persistence / progression of disease for which the infusion was
performed
• If the cause of death is due to disease, ensure disease detected is reported on
the appropriate post-infusion follow-up form.
• If the disease is present at death, but is not the underlying cause of death, this
should be reported as a contributing cause of death.
o Example: The recipient’s disease had been stable for months and they
died by accidental means, this option should be used as a contributing
cause of death (not the primary cause of death).
GVHD

The determination of acute versus chronic GVHD should rest on clinical features
identified by the clinician.
Acute GVHD: If this is reported as a primary or contributing cause of death,
acute GVHD should also be reported on the appropriate post-infusion form.
Chronic GVHD: If this is reported as a primary or contributing cause of death,
chronic GVHD should also be reported on the appropriate post-infusion form.

Graft failure or poor graft function
• The recipient had no hematopoietic recovery, graft failure following initial
hematopoietic recovery, or poor graft function.
• If secondary graft failure is due to GVHD or infection, also report GVHD or
infection as causes of death.
Failure to thrive
• A term used to describe a global decline which includes inactivity, weight loss,
and decreased appetite.
Hemorrhage
• Recipient died with evidence of hemorrhage. Use the following options to report
the hemorrhage location: Diffuse alveolar hemorrhage (DAH),
Gastrointestinal hemorrhage, Hemorrhagic cystitis, Intracranial
hemorrhage, Pulmonary hemorrhage, or Other hemorrhage.
• Additional details:
o Diffuse alveolar hemorrhage (DAH): If this is reported as the primary or
contributing cause of death and the recipient is on the CRF track, also
report this on the Post-Infusion Follow-Up (2100) Form.
o Hemorrhagic cystitis: If this is reported as the primary or contributing
cause of death and the recipient is on the CRF track, also report this on
the Post-Infusion Follow-Up (2100) Form.
o Intracranial hemorrhage: Also known as hemorrhagic stroke. If this is
reported as the primary or contributing cause of death and the recipient is
on the CRF track, also report this on the Post-Infusion Follow-Up (2100)
Form.
o Pulmonary hemorrhage: If this is reported as the primary or contributing
cause of death and the recipient is on the CRF track, also report this on
the Post-Infusion Follow-Up (2100) Form.
o Other hemorrhage: Select this option if the hemorrhage was in an organ
system that does not have a cause of death option and report the organ or
location of the hemorrhage in the Specify data field.
Infection
• Recipient died due to an infection. Use the following options to specify the
infection etiology: Bacterial infection, Fungal infection, Protozoal infection,
Viral infection, or Other infection.

Malignancy
• Recipient died with evidence of a malignancy other than the primary disease for
infusion. Use the options below to specify the type of malignancy.
• New malignancy: If the recipient developed a new malignancy post-infusion,
including PTLD, this should also be reported on the appropriate post-infusion
form.
• Prior malignancy: If there was a history of malignancy prior to infusion (i.e., not
the primary disease for infusion) and the recipient died with evidence of
recurrence, persistence, or progression of the previous malignancy. This should
also be reported on the appropriate pre-infusion form.
Organ failure (not due to GVHD or infection)
• Recipient died with organ failure, not due to GVHD or infection. Use the options
below to specify the organ system that failed.
• Cardiac failure: If cardiac failure was related to congestive heart failure and / or
myocardial infarctions, also report this on the appropriate Post-Infusion FollowUp (2100) Form.

• Other cause: If the cause of death is not listed above, select Other cause and
specify. Do not include sepsis / septic shock or pneumonia.

Q1 – 4: Recipient Death
No Documentation of Contact Date
The contact date data field cannot be left blank and is required to be reported. In cases
where the recipient passed away and there is no documentation to report the date of
death, the guidelines for reporting estimated dates must be used.
Question 1: Date of Death
Report the date the recipient died. Confirm that the date matches the last date of actual
contact reported on the Post-TED (2450), Post-Infusion Follow-Up (2100), or Cellular
Therapy Essential Data Follow-Up (4100) form.
If the death occurred at an outside location and records of death are not available, the
dictated date of death within a physician note may be reported. If the progress notes
detailing the circumstances of death are available, request these records. These
records are useful for completing required follow-up data fields on the post-infusion
forms and the cause of death data fields on this form.
If the exact date of death is not known, select Date estimated and use the process
described for reporting partial or unknown dates in General Instructions, Guidelines for
Completing Forms
Question 2: Was cause of death confirmed by autopsy?

Indicate if the cause of death was confirmed by autopsy.
If Autopsy pending, the form will not go to complete (CMP) status until the autopsy
results are reported. The form may be submitted with this question answered
as Autopsy pending, but the form will remain in saved (SVD) status until it is updated
with the results. Once the autopsy results are known, update this question and
the Primary cause of death, if applicable, to ensure all pertinent causes of death are
reported, then resubmit to complete the form.
Autopsy Report
It is strongly encouraged to attach the autopsy report if documentation is available.
For further instructions on how to attach documents in FormsNet3SM, refer to
the training guide.
Primary and Contributing Cause(s) of Death
Report the primary and contributing cause(s) of death based on the physician’s
determination. If the cause of death is unclear, seek physician clarification to determine
the appropriate cause of death.
Cause of Death Options
Review the Cause of Death Options section for additional information to ensure
accurate cause of death reporting.
Questions 3 – 4: Primary cause of death
Report the underlying cause of death. According to the Centers for Disease Control and
Prevention, National Center for Health Statistics, the underlying cause of death is “the
disease or injury that initiated the chain of events that led directly or inevitably to death.”
Report only one primary cause of death. If additional details are required, the Specify
data field will be answered. Information reported in the Specify field must pertain to the
option selected (i.e., an infectious cause of death should be specified for Other
infection).
If the recipient has recurrent / persistent / progressive disease at the time of death,
consider if the disease was the primary cause of death or a contributing cause of death.
It should not be assumed that the presence of the recipient’s primary disease indicates
that the disease was the primary cause of death.
If a cause of death has related questions on the comprehensive report form, report the
appropriate data in both locations. For example, if a primary cause of death was
infection, complete the infection data fields on the comprehensive report form. Review
the Cause of Death Options section for additional details.

If the primary cause of death is unclear, consult with a physician for their best medical
opinion.

Q5 – 7: Contributing Cause of Death
Primary and Contributing Cause(s) of Death
Report the primary and contributing cause(s) of death based on the physician’s
determination. If the cause of death is unclear, seek physician clarification to determine
the appropriate cause of death.
Cause of Death Options
Review the Cause of Death Options section for additional information to ensure
accurate cause of death reporting.
Questions 5 – 6: Contributing cause of death (check all that apply)
Report any additional causes of death. All contributing causes of death are important for
analysis of transplant outcomes. Select all that apply.
If additional details are required, the Specify data field will be answered. Information
reported in the Specify field must pertain to the option selected (i.e., an infectious cause
of death should be specified for Other infection).
If a cause of death has related questions on the comprehensive report form, report the
appropriate data in both locations. For example, if a contributing cause of death was
acute graft-versus-host disease (GVHD), complete the acute GVHD data fields on the
comprehensive report form.
Review the examples below on how to report primary and contributing cause of death:
• Example 1: In the 1-year reporting period, a recipient transplanted for AML has
relapsed disease that leads to multiple organ failure. In this scenario, the primary
cause of death should be captured as relapsed disease, and the contributing
cause of death should be reported as multiple organ failure.
• Example 2: A recipient with acute GVHD on immunosuppression develops a
fungal infection and then dies. In this scenario, the primary cause of death should
be reported as acute GVHD, and the contributing cause of death would be
captured as a fungal infection.

DRAFT Subsequent Neoplasm
CIBMTR Form 3500

Instructions for Subsequent Neoplasm (3500) Form
This section of the CIBMTR Forms Instruction Manual is intended to be a resource for
completing the Subsequent Neoplasm (3500) Form.

Subsequent Neoplasm (3500)
The Subsequent Neoplasms (3500) form must be completed when a new malignancy is
reported on the Post-TED (2450), Post-Infusion Follow-Up (2100) or Cellular Therapy
Essential Data Follow-Up (4100) forms. Reported new malignancies should be different
than the disease / disorder for which the infusion or cellular therapy was performed. Do
not report relapse, progression, or transformation of the same disease subtype as a
new malignancy.
New malignancies, lymphoproliferative disorders, and myeloproliferative disorders
include but are not limited to:
• Skin cancers (basal, squamous, melanoma)
• New leukemia
• New myelodysplasia
• Solid tumors
• PTLD (post-transplant lymphoproliferative disorder) report as non-Hodgkin
lymphoma
The following should not be reported as new malignancy:
• Recurrence of primary disease (report as relapse or disease progression)
• Relapse of malignancy from recipient’s pre-cellular therapy medical history
• Breast cancer found in other (i.e., opposite) breast (report as relapse)
• Post-cellular therapy cytogenetic abnormalities associated with the pre-cellular
therapy diagnosis (report as relapse)
A separate Subsequent Neoplasm (3500) Form must be submitted to report each new
malignancy diagnosed in the current reporting period. Reporting a new malignancy /
disorder on a Post-TED (2450), Post-Infusion Follow-Up (2100) or Cellular Therapy
Essential Data Follow-Up (4100) Form will make one Subsequent Neoplasm (3500)
Form come due. This form will also have the option to be created on-demand (ondemand is when a form can be generated at any time). If more than one new
malignancy occurs during a reporting period, the Subsequent Neoplasm (3500) Form
can be made on demand. Contact CIBMTR Center Support with any questions.

Q1 – 11: New Malignancy, Lymphoproliferative or Myeloproliferative
Disease / Disorder
Reporting Multiple New Malignancies
A single Subsequent Neoplasms (3500) form will come due whenever a new
malignancy / disorder is reported on the Post-TED (2450), Post-HCT Follow-Up (2100)
or Cellular Therapy Essential Data Follow-Up Form (4100) form. However, if there is a
diagnosis of more than one malignancy in the reporting period, excluding nonmelanoma skin cancers (see Recurrent Non-Melanoma Skin Cancers note box below),
a separate Subsequent Neoplasms (3500) form must be submitted to report each new
malignancy.
Recurrent Non-Melanoma Skin Cancers
For basal cell or squamous cell skin cancer, report the number of skin cancer lesions
diagnosed in the current reporting period. If basal cell or squamous cell skin cancer was
diagnosed again in a future reporting period, report Yes, a new malignancy occurred on
the appropriate post-infusion follow-up form and specify the number of skin cancer
lesions identified in the reporting period. For example, a recipient was diagnosed with
basal cell skin cancer on the neck in the one-year reporting period and two months

later, within the same reporting period, there was a diagnosis of basal cell located on
the nose. In the two-year reporting period, another basal cell skin cancer was
diagnosed, located on the arm. For the one-year reporting period, report Yes, there was
a new malignancy on the one-year post-infusion follow-up form and a single
Subsequent Neoplasms (3500) form will come due to report both basal cell
malignancies detected (report two in Number of non-melanoma skin cancer lesions).
For the two-year reporting period, report Yes, there was a new malignancy on the twoyear post-infusion follow-up form and a single Subsequent Neoplasms (3500) form will
come due to report third basal cell malignancies detected (report one in Number of nonmelanoma skin cancer lesions).
Post-Transplant Lymphoproliferative Disorder (PTLD)
PTLD should be reported as a new malignancy if it was confirmed via a biopsy
(treatment not required) or suspected to be PTLD and treated.
New Malignancy Documentation
The submission of pathology reports and other supportive documentation for each
reported new malignancy is strongly recommended.
For instructions on how to attach documents in FormsNet3SM, refer to the Training
Guide.

any applicable questions.
If the new malignancy / disorder is not found in the list, select Other new
malignancy and specify. An example of an Other new malignancy includes histiocytic
sarcoma.
Report myeloid sarcoma as Acute myeloid leukemia (AML / ANLL).
Do not report CNS relapse of lymphoma as a new malignancy for recipients whose
primary disease for infusion is lymphoma. This should be reported as relapse. However,
in cases where a recipient received an infusion for a disease other than lymphoma and
later develops CNS lymphoma, lymphoma should be reported as a new malignancy.
Question 2: Specify type of PTLD
Specify the type of PTLD as Monomorphic or Polymorphic using the guidelines listed
below. The PTLD type should be documented within the pathology report, if available. If
the documentation is unclear, seek clinician clarification.
