Study of Genes & the Environment in Patients With Colorectal Cancer in

Status Recruiting

Clinical Trial Summary

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 colorectal cancer.

Clinical Trial Description

OBJECTIVES:

- To obtain epidemiological information and biological material on a population based series of colorectal cancer cases.

- To define the proportion of colorectal cancer incidence attributable to mutations in known predisposing genes such as MLH1 and MSH2.

- To establish whether mutations at other loci may predispose to colorectal cancer, by comparing the frequency of alteration candidate genes in colorectal cancer patients with the corresponding frequency 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 also requests identifying information about the patient's first-degree relatives.

Blood samples are collected from patients. DNA is extracted from these blood samples, from samples collected from cancer-free control participants in MREC-SEARCH-CONTROL, and 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 colorectal cancer patients recruited for this study, patients with breast, ovarian, prostate, colorectal, bladder, kidney, pancreatic, brain, and esophageal cancer, malignant melanoma, and lymphoma cancer are recruited for the following related clinical trials: MREC-SEARCH-BREAST, MREC-SEARCH-OVARIAN, MREC-SEARCH-PROSTATE, MREC-SEARCH-ENDOMETRIAL, and MREC-SEARCH-CANCER. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
