Brief Summary:

RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that may occur in the immune system that may help kill cancer cells.

PURPOSE: This laboratory study is looking at anticancer immune responses in the peripheral blood of patients with colon cancer.

Condition or disease Intervention/treatment
Colorectal Cancer Other: immunoenzyme technique Other: laboratory biomarker analysis

Detailed Description:


  • Quantify T cells specific for tumor peptides (carcinoembryonic antigen and MUC1) from the peripheral blood of patients with colon cancer.

OUTLINE: This is an open-label study.

Patients undergo blood collection at time of follow-up, surgery, thoracentesis, paracentesis, or leukapheresis (≤ 5 times per year). Blood is analyzed for tumor peptides (carcinoembryonic antigen and MUC1), circulating cytokines, and lymphocyte response by ELISA, ELISPOT, or intracellular flow.

PROJECTED ACCRUAL: A total of 140 patients will be accrued for this study.

Study Type : Observational
Actual Enrollment : 67 participants
Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Immune Studies of Peripheral Blood From Patients With Malignant Disease Gastrointestinal Tract
