  Purpose

RATIONALE: Genetic studies may help in understanding the genetic processes that cause some types of cancer.

PURPOSE: Genetic trial to study certain genes of patients who have stage II or stage III colon cancer.


Condition Intervention
Colorectal Cancer
Genetic: DNA stability analysis
Genetic: gene mapping

Study Type: Observational
Official Title: The Clinical and Pathological Significance of Allelic Imbalance of 8p in Patients With Colorectal Cancer

Study Start Date: February 1999
Detailed Description:

OBJECTIVES:

  • Determine the adverse prognostic significance of 8p allelic imbalance (AI) in patients with colon cancer.
  • Determine if patient prognosis is dependent on the region of 8p AI.
  • Perform fine mapping studies to further localize the putative tumor suppressor gene(s) on 8p.
  • Perform multicolor FISH to examine the role that 8p loss and 8q gain play in the prognosis of patients whose tumors exhibit 8p AI.

OUTLINE: Matched normal and tumor DNA is analyzed for 8p allelic imbalance with at least 8 markers: D8S262 and D8S1825 localized to 8p23, D8S254 and D8S261 at 8p22, D8S560 and D8S136 at 8p21, and D8S1820 and D8S283 at 8p12. Normal/tumor tissue pairs are used for fine mapping studies.

PROJECTED ACCRUAL: Approximately 480 patients will be accrued for this study.
