Study of Genes and the Environment in Patients With Ovarian Cancer in the East Anglia, Oxford, Trent, or West Midlands Regions of the United Kingdom
A Population Based Study of Genetic Predisposition and Gene-Environment Interactions in Ovarian Cancer in East Anglia, Oxford, Trent and West Midlands
RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.
PURPOSE: This study is looking at genetic susceptibility for cancer and interactions between genes and the environment in patients with ovarian cancer.

Detaillierte Beschreibung
OBJECTIVES:
- To obtain epidemiological information and biological material on a population-based series of ovarian cases.
- To define the proportion of ovarian cancer incidence attributable to mutations in known predisposing genes (e.g., BRCA1 and BRCA2).
- To determine the risk associated with predisposing mutations by examining the cancer risks in relatives of patients who are shown to be carriers.
- To examine the effect of nongenetic risk factors in mutation carriers.
- To determine the pathological and clinical characteristics of ovarian cancers occurring in BRCA1/2 mutation carriers as compared with that in noncarriers.
- To establish whether mutations at other loci may predispose to ovarian cancer by comparing the frequency of alterations in ovarian cancer patients with that in cancer-free controls identified through the European Prospective Investigation of Cancer (EPIC) study.
OUTLINE: This is a multicenter study.
Patients complete an epidemiological questionnaire. The questionnaire will request identifying information on the patient's first-degree relatives.
Blood samples are collected from patients. DNA is extracted from these blood samples and from samples collected from cancer-free control participants in MREC-SEARCH-CONTROL as well as from additional controls through the European Prospective Investigation of Cancer (EPIC) study (a population based study of diet and health based in Norfolk, East Anglia). DNA samples are analyzed for polymorphisms of low penetrance cancer susceptibility genes.
In addition to the ovarian cancer patients recruited for this study, patients with breast, endometrial, prostate, colorectal, bladder, kidney, pancreatic, brain and esophageal cancer, malignant melanoma, and lymphoma cancer are recruited in the following related clinical trials: MREC-SEARCH-BREAST, MREC-SEARCH-ENDOMETRIAL, MREC-SEARCH-PROSTATE, MREC-SEARCH-COLORECTAL, and MREC-SEARCH-CANCER.
