Study of Genes and Environment in Patients With Cancer in East Anglia, Trent, or West Midlands Regions of the United Kingdom
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 to cancer and interactions between genes and the environment in patients with cancer in East Anglia, Trent, or West Midlands of the United Kingdom.
- To obtain epidemiological information and biological material on a population-based series of cancer cases, including malignant melanoma, lymphoma, bladder, kidney, esophageal, and pancreatic cancer, and brain tumors.
- Identify novel cancer susceptibility genes, by comparison of genotype frequencies in cases with the corresponding frequencies in large control series.
- To estimate the age and sex-specific risks associated with variants in predisposition genes.
- To evaluate interactions between polymorphisms in predisposition genes and potential lifestyle risk factors.
OUTLINE: This is a multicenter study.
Patients complete a detailed epidemiological questionnaire that includes information on education, occupation, smoking habits, alcohol consumption, height, weight, reproductive history (age at menarche, age at pregnancies, parity, and age at menopause), oral contraceptive use, hormone replacement therapy use, family history of cancer, and past medical history.
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 cancer patients recruited for this study, patients with breast, ovarian, endometrial, colorectal, and prostate cancer are recruited for the following related clinical trials: MREC-SEARCH-BREAST, MREC-SEARCH-OVARIAN, MREC-SEARCH-ENDOMETRIAL, MREC-SEARCH-COLORECTAL, and MREC-SEARCH-PROSTATE.

Medical and Biotech [MESH] Definitions
A method of chemical analysis based on the detection of characteristic radionuclides following a nuclear bombardment. It is also known as radioactivity analysis. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
Amplified Fragment Length Polymorphism Analysis
The detection of RESTRICTION FRAGMENT LENGTH POLYMORPHISMS by selective PCR amplification of restriction fragments derived from genomic DNA followed by electrophoretic analysis of the amplified restriction fragments.
Analysis based on the mathematical function first formulated by Jean-Baptiste-Joseph Fourier in 1807. The function, known as the Fourier transform, describes the sinusoidal pattern of any fluctuating pattern in the physical world in terms of its amplitude and its phase. It has broad applications in biomedicine, e.g., analysis of the x-ray crystallography data pivotal in identifying the double helical nature of DNA and in analysis of other molecules, including viruses, and the modified back-projection algorithm universally used in computerized tomography imaging, etc. (From Segen, The Dictionary of Modern Medicine, 1992)
The simultaneous analysis, on a microchip, of multiple samples or targets arranged in an array format.
Sequence Analysis, Dna
A multistage process that includes DNA cloning, physical mapping, subcloning, sequencing, and information analysis.
