OBJECTIVES: * Determine whether the immunohistochemical and molecular presence of micrometastases in ≥ 12 lymph nodes removed during en-bloc resection in patients with stage II colon cancer correlates with 3-year disease-free survival. * Evaluate the prognostic significance of molecular markers detected in the primary tumor and develop a microarray-based gene signature for stage II colon cancer. OUTLINE: This is a multicenter study. Tumor tissue and regional lymph node samples are collected during surgery for analysis of micrometastases and molecular markers by immunohistochemistry, qRT-PCR, MM qRT-PCR, qRDNA-PCR, and microarray profiling. Patients are followed up periodically for 4 years after surgery.
