Mucinous Adenocarcinoma of the Colon, Signet Ring Adenocarcinoma of the Colon, Stage IIA Colon Cancer, Stage IIB Colon Cancer, Stage IIC Colon Cancer
Conditions
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.

Inclusion criteria
* Pathologic documentation of adenocarcinoma of the colon with or without penetration of the serosa with no lymph node metastases (Stage II pT3N0 or pT4bNO lesions, excluding pT4aN0; Modified Astler-Coller Stage B2); there can be no distant metastases or penetration of adjacent organs or structures; proximal, distal, and radial margins must be free of tumor Important note: A tumor nodule \> 3 mm in diameter in the perirectal or pericolonic adipose tissue without histologic evidence of residual node in the nodule is classified as regional/pericolonic node metastasis; however, a tumor nodule =\< 3 mm in diameter is classified in the T category as discontinuous extension (i.e., pT3); multiple metastatic foci seen microscopically only in the pericolonic fat should be considered as metastasis in a single lymph node for classification; although six or more nodes evaluated from the specimen is optimal, a minimum of three nodes (periodic or mesenteric) for evaluation is required for inclusion in the study * Complete, en bloc resection of all the primary tumor, performed as an open procedure, and not laparoscopically or laparoscopically assisted * No evidence of perforation or clinical obstruction of the bowel * The gross distal margin of the primary tumor must lie above the peritoneal reflection (i.e., it must be a colon, not a rectal cancer) * No previous radiation or chemotherapy for this malignancy * CALGB Performance status 0-1 * No concurrent treatment with systemic steroids is allowed; patients receiving replacement steroids for adrenal insufficiency are eligible; patients receiving inhaled steroids in daily doses of 500mg or less and patients being treated with topical steroids are eligible * No prior exposure to murine antibodies (e.g., diagnostic tests like the "oncoscint scan") * No uncontrolled or severe cardiovascular disease * No history of pancreatitis * Non-pregnant and non-lactating; patients of child-bearing potential should agree to use an effective method of birth control * No previous or concurrent malignancy is allowed, except inactive non-melanoma skin cancer, in situ carcinoma of the cervix, or other cancer if the patient has been disease-free for \>= 5 years; patients with more than one synchronous primary colon tumor are eligible; for the purpose of this protocol, staging classification will be based on the stage of the more advanced primary tumor * Granulocytes \> 1,800/μl * Platelet count \> 100,000/μl * BUN \< 1.5 x normal * Creatinine \< 1.5 x normal * Bilirubin \< 1.5 x normal
