简要总结
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. It is not yet known whether combination chemotherapy is more effective with or without bevacizumab in treating metastatic colorectal cancer.
PURPOSE: This randomized phase III trial is studying second-line combination chemotherapy to see how well it works compared with or without bevacizumab in treating patients with metastatic colorectal cancer who have received first-line chemotherapy and bevacizumab.
详细描述
OBJECTIVES:
Primary
- To compare the progression-free survival of second-line chemotherapy with or without bevacizumab in patients with metastatic colorectal cancer who have received first-line chemotherapy with bevacizumab.
Secondary
- To compare the overall survival, response rate, and safety profile of second-line chemotherapy of these regimens in these patients.
- To conduct pharmacogenomics assessment of candidate variants in the VEGF gene and evaluate their association with progression-free survival and other study outcomes.

Arm I
Patients receive either irinotecan hydrochloride over 1 hour or oxaliplatin over 1 hour on day 1. Patients also receive leucovorin calcium IV over 2 hours and fluorouracil IV over 46 hours continuously beginning on day 1. Treatment repeats every 2 weeks for up to 12 courses in the absence of disease progression or unacceptable toxicity.
干预措施: fluorouracil (Drug)
