Spots Global Cancer Trial Database for Edrecolomab in Treating Patients With Stage II Colon Cancer

Study Description

Brief Summary: Randomized phase III trial to compare the effectiveness of surgery with or without monoclonal antibody therapy in treating patients who have stage II colon cancer. Monoclonal antibodies such as edrecolomab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. It is not yet known whether surgery to remove colon cancer is more effect with or without monoclonal antibody therapy.

Detailed Description: PRIMARY OBJECTIVES: I. To determine whether adjuvant treatment with MoAb 17-1A will improve the probability of overall and disease-free survival, and increase disease-free intervals in patients who have undergone resection of a Stage II colon cancer. II. To determine whether alterations in the expression of cell cycle related genes (thymidylate synthase, p53, and the cyclin-dependent kinase inhibitors p21 and p27) predict the risk of survival and recurrence in this patient population. III. To determine whether alterations in markers of metastatic potential-expression of DCC and measures of tumor angiogenesis (microvascular density and vascular endothelial growth factor expression)-predict the risk of survival and recurrence in this patient population. IV. To determine whether a marker of cellular differentiation-sucrase isomaltase-predicts the risk of survival and recurrence in this patient population. V. To determine whether DNA ploidy and cell proliferation are prognostic of tumor recurrence and overall survival in Stage II colon cancer. VI. To determine whether interactions among these tumor markers identify subsets of patients with significantly altered outcome. VII. To determine whether pathologic features including tumor grade; tumor mitotic (proliferation) index; tumor border configuration; host lymphoid response to tumor; and lymphatic vessel, venous vessel and perineural invasion predict outcome in this patient population. OUTLINE: This is a randomized study. Patients are stratified according to degree of differentiation (well vs moderately well vs poor), vascular or lymphatic invasion (no vs yes), and preoperative serum CEA (less than 5.0 ng/mL vs at least 5.0 ng/mL vs unknown). Patients are randomized to 1 of 2 treatment arms. Arm I: Patients receive adjuvant edrecolomab IV over 2 hours on day 1. Treatment repeats every 28 days for 5 courses. Patients must begin therapy no earlier than 7 days and no later than 42 days post-surgical resection. Patients also undergo observation at 3 and 6 months post-randomization. Arm II: Patients undergo observation at 3 and 6 months post-randomization. Patients are followed after the last course of edrecolomab (arm I) and at 12 months (arm II). All patients are followed every 6 months for 5 years.
