DESCRIPTION (provided by applicant):
The specific aim of this Australasian center-specific proposal is to renew
activities as part of a six-center consortium known as the Cooperative Family
Registry(CFR) for colorectal cancer. The aim of the CFR is to accrue
colorectal cancer families according to a protocol that includes the
generation of a repository of biospecimens (blood and tumour samples),and
comprehensive lifestyle data obtained through standardized epidemiologic
questionnaires, so as to support research from groups within and outside the
CFR. To achieve this, over the next five years we will:
1. Recruit 320 population-based colorectal cancer cases diagnosed before the
age of 50, regardless of family history,and 250 clinic-based families with at
least three cases, as part of the Accrual Component.
2. Not contribute to the Minorities Component.
3. Conduct follow-up activities with all subjects(except controls and
relatives of controls)who consented to be participants in the CFR during the
first phase of recruitment and data collection(July 1997 - July2002), as well
as all new participants who will be recruited in Year 01 to 04 of the renewal
in 1. above. We plan both active follow-up at 4 and 6 years after original
enrolment, and annual passive follow-up, including a Newsletter. We estimate
that our follow-up will involve 10,217 individuals in 1,356 families.
4. Participate in the Molecular Characterization Component by contributing
appropriate samples to GMP and the participating CFR laboratories. We estimate
that we will prepare, ship, and track samples as follows:556 for DNA
sequencing,856 for methylation, and 126 samples for GMP conversion mutation
analysis.
5. Maintain the biospecimens repository comprising blood samples and tumor
blocks and/or paraffin sections and respond to approved requests for samples.
6. Maintain our bioinformatics support activities so that we can respond to
queries from CFR and non-CFR investigators, support local analyses, and
coordinate activities with the Informatics Support Center (ISC).
7. Develop and maintain a fresh frozen tissue repository on selected, newly
diagnosed cases that will contain tissues from 30 colorectal cancers or polyps
obtained per year from subjects treated within Queensland.
8. Conduct Pilot studies that will continue the innovative molecular and
pathology work by Professor Jass and his laboratory to further unravel the
genetic heterogeneity of hereditary colorectal cancer. We shall use the
results of the statistical Pilot Study to develop the machinery for analyzing
the accrued data, make blood collection and extension of families more
efficient and informative, and provide a better resource for future gene
discovery.
