Combination Chemotherapy and Bevacizumab Before Surgery and Radiolabeled Monoclonal Antibody Therapy in Treating Liver Metastases in Patients With Metastatic Colorectal Cancer

PRIMARY OBJECTIVES: I. To determine the progression free survival in colorectal cancer patients after hepatic resection of liver metastases and FOLFOX or leucovorin calcium, fluorouracil, and irinotecan hydrochloride (FOLFIRI) chemotherapy \[+/- Bevacizumab\], or capecitabine and oxaliplatin (XELOX),followed by intravenous (IV) yttrium-90 (90Y) M5A anti-CEA antibody. SECONDARY OBJECTIVES: I. To study the feasibility and toxicities of such adjuvant therapy following resection and/or ablation of liver metastases and FOLFOX chemotherapy. II. To evaluate the biodistribution, clearance and metabolism of 90Y and 111In (indium-111) M5A administered IV. OUTLINE: FOLFOX\* + BEVACIZUMAB CHEMOTHERAPY: Patients receive oxaliplatin IV over 2 hours, leucovorin calcium IV over 2 hours, fluorouracil IV continuously over 46-48 hours, and bevacizumab IV over 30-90 minutes. Treatment repeats for up to 12 courses in the absence of disease progression or unacceptable toxicity. RADIOIMMUNOTHERAPY (RIT): Within 4-12 weeks after completion of post-hepatic resection therapy chemotherapy, patients receive yttrium Y 90 DOTA anti-CEA monoclonal antibody M5A IV over 25 minutes. Treatment repeats every 6-10 weeks for 2 courses in the absence of disease progression or unacceptable toxicity. NOTE:\*Patients previously failing oxaliplatin regimen receive FOLIFIRI chemotherapy comprising irinotecan hydrochloride IV over 90 minutes, leucovorin calcium over 2 hours, fluorouracil IV continuously over 46-48 hours, and bevacizumab IV over 30-90 minutes. Treatment repeats for up to 6 courses in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 3 and 6 months.
