This phase II trial studies how well giving combination chemotherapy and bevacizumab before surgery and radiolabeled monoclonal antibody therapy works in treating liver metastases in patients with metastatic colorectal cancer. Drugs used in chemotherapy, such as leucovorin calcium, fluorouracil, and oxaliplatin (FOLFOX), work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Radiolabeled monoclonal antibodies, such as yttrium Y 90 DOTA anti-CEA monoclonal antibody M5A, can find tumor cells and carry tumor-killing substances to them without harming normal cells. Giving chemotherapy and monoclonal antibody before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving radiolabeled monoclonal antibody therapy after surgery may kill any tumor cells that remain after surgery
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.

Progression-free Survival
Estimated using the product-limit method of Kaplan-Meier, and 95% confidence limits calculated for these estimates. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
Time frame: Up to 24 months
Overall Survival
Overall Survival is calculated for all patients from the date of initial treatment to date of death due to any cause. Patients who were still alive were censored at the date of last follow-up. Survival rates were estimates using the Kaplan-Meier method, and 95% confidence limits calculated for these estimates.
Time frame: Up to 5 years
