  Purpose

RATIONALE: Analyzing the structure of genes found in a person's cancer cells may help doctors improve methods of treating patients with colon cancer.

PURPOSE: Clinical trial to study the genes of patients treated with chemotherapy for colon cancer.


Condition Intervention
Colorectal Cancer
Genetic: mutation analysis
Genetic: tumor replication error analysis

Study Start Date: August 1998
Detailed Description:

OBJECTIVES:

  • Determine the relationship between disease free survival, overall survival, and tumor replication error status for patients who have received adjuvant chemotherapy for colon cancer on CALGB protocol 8896.
  • Determine the prognostic and predictive values for response to this therapy in these patients.

OUTLINE: Samples of tumor and normal tissue are obtained from CALGB 8896 patients. The samples are tested for somatic mutations and tumor replication error (RER) tumor status.

Patients do not receive the results of the genetic testing and the results do not influence the type or duration of treatment.

PROJECTED ACCRUAL: At least 300 specimens will be accrued for this study.
