Primary Outcome Measures:
  • Quantitation of T cells specific for tumor peptides (carcinoembryonic antigen and MUC1) [ Time Frame: 3 months ] [ Designated as safety issue: No ]

Enrollment: 67
Study Start Date: July 2004
Study Completion Date: December 2008
Primary Completion Date: December 2008 (Final data collection date for primary outcome measure)
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.
