This trial is designed to determine if
screening for prostate, lung, colorectal and ovarian cancer can
reduce mortality from these cancers which currently cause an
estimated 254,570 deaths annually in the U.S. The design is a
two-armed randomized trial of men and women aged 55 to 74 at entry.
OMB first approved this study in 1993 and has approved it every 3
years since then through 2011. During the first approval period a
pilot study was conducted to evaluate recruitment methods and data
collection procedures. Recruitment was completed in 2001 and data
collection continues through 2014. When participants enrolled in
the trial they agreed to be followed for at least 13 years from the
time of enrollment. The current number of respondents in the study
is 122,655; this is down from the initial total due to deaths. The
primary endpoint of the trial is cancer specific mortality for each
of the four cancer sites (prostate, lung, colorectal, and ovary).
In addition, cancer incidence, stage shift, and case survival are
to be monitored to help understand and explain results. Biologic
prognostic characteristics of the cancers will be measured and
correlated with mortality to determine the mortality predictive
value of these intermediate endpoints. Basic demographic data, risk
factor data for the four cancer sites and screening history data,
as collected from all subjects at baseline, will be used to assure
comparability between the screening and control groups and make
appropriate adjustments in analysis. Further, demographic and risk
factor information may be used to analyze the differential
effectiveness of screening in high versus low risk
individuals.
This is a program change of the
previously approved study due to OPDIV discretion; also considered
a revision. Both the total number of respondents and the total
burden hours have increased since the last submission due to the
re-introduction of the Supplemental Questionnaire (SQX). The SQX
substantially increases the average time per response. This
questionnaire updates information on demographics, cancer risk
factors, and history of cancer screening. The addition of a
telephone script to contact respondents who do not return the ASU
also contributed to the increase in respondents and burden hours.
In addition to an increase in burden, another change from the 2008
application is that the Prostate Cancer Reoccurrence Questionnaire
(PCR) project will be completed under the current approval period.
The PCR Questionnaire will no longer be administered and has not
been included in this submission. The PCRQ is no longer being used
since that data collection effort will be completed by September
29, 2011.
