Participant gender:
All
Summary
RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors understand how patients respond to treatment. PURPOSE: This clinical trial is studying biomarkers in patients with rectal cancer undergoing chemotherapy and radiation therapy.
