RATIONALE: Determination of genetic markers for colorectal cancer may improve the identification of patients who are at highest risk for relapse.
PURPOSE: This clinical trial is studying the importance of genetic markers for detecting relapse in patients with colorectal cancer.

Procedure: DNA stability analysis Procedure: loss of heterozygosity analysis Procedure: microsatellite instability analysis |
Study Type: | Observational |
Official Title: | Clinical Significance of Genetic Markers in Colon Cancer |
Study Start Date: | September 1997 |
OBJECTIVES:
OUTLINE: DNA is examined for unstable elements (microsatellite instability and loss of heterozygosity) by analyzing at least 10 separate (CA)n-repeats localized to 5 separate chromosomes (5q, 8p, 15, 17p, and 18q). Loss of heterozygosity is analyzed for at least four chromosomal arms (5q, 8p, 17p, and 18q) and later other chromosomes (e.g., 1, 14, and 22). Immunohistochemistry is used to test for the presence or absence of the genes involved in DNA mismatch repair (hMLH1 and hMSH2).
Patients do not receive the results of the genetic testing and the results do not influence the type or duration of treatment.
PROJECTED ACCRUAL: This study will accrue up to 708 specimens.
