This is a request for a revision due
to the replacement of the Supplemental Questionnaire with the
Medication Use Questionnaire (MUQ). The previous submission was
approved in September, 2011. This trial was designed to determine
if cancer screening for prostate, lung, colorectal, and ovarian
cancer can reduce mortality from these cancers which currently
cause an estimated 255,700 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. Recruitment was completed in 2001,
baseline cancer screening was completed in 2006, and data
collection continues on the current cohort of 94,000 participants
who are actively being followed. The additional follow-up will
provide data that will clarify further the long term effects of the
screening on cancer incidence and mortality for the four targeted
cancers. Further, demographic and risk factor information may be
used to analyze the differential effectiveness of cancer 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. Number of responses to the follow up forms in the PLCO
is consistently declining because more deaths are occurring as the
study participant's age. In the 2008, the estimated number of
responses was 131,341, however due to death rates it was only
122,655 responses. In 2011, the estimated number of annual
responses was 191,600; a substantial increase from the previous
submission because a new questionnaire, the Supplemental
Questionnaire (SQX), was introduced (30 minutes to 93,000
respondents). The current number of annual responses estimated for
this submission is 193,760; a slight increase from the previous
submission due to an underestimate of the number of participants
who consented to active follow-up from the first eight screening
centers. However, the total number of burden hours has decreased
since the last submission primarily due to the replacement of the
Supplemental Questionnaire with the Medication Use Questionnaire.
The decrease in burden hours is not as large as expected due to the
increase in number of respondents.
On behalf of this Federal agency, I certify that
the collection of information encompassed by this request complies
with 5 CFR 1320.9 and the related provisions of 5 CFR
1320.8(b)(3).
