Summary
RATIONALE: Drugs used in chemotherapy, such as irinotecan, oxaliplatin, leucovorin, and fluorouracil, 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 cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving combination chemotherapy together with bevacizumab may kill more tumor cells. PURPOSE: This randomized phase III trial is comparing two combination chemotherapy regimens given together with bevacizumab to see how well they work as first-line therapy in treating patients with metastatic colorectal cancer that cannot be removed by surgery.Phase:
