简要总结
RATIONALE: Drugs used in chemotherapy 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 cetuximab, 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 giving combination chemotherapy together with intermittent cetuximab is more effective than combination chemotherapy given together with continuous cetuximab in treating colorectal cancer.
PURPOSE: This randomized phase II trial is studying giving combination chemotherapy together with intermittent cetuximab to see how well it works compared to combination chemotherapy given together with continuous cetuximab as first-line therapy in treating patients with advanced or metastatic colorectal cancer.
详细描述
OBJECTIVES:
Primary
- To compare the activity, in terms of failure-free survival, of patients with K-ras-normal (wild type) advanced and/or metastatic colorectal cancer treated with intermittent combination chemotherapy comprising oxaliplatin, leucovorin calcium, and fluorouracil (OxMdG) or oxaliplatin and capecitabine (XELOX) and intermittent vs continuous cetuximab as first-line therapy.
- To compare the safety and feasibility of these regimens in these patients.
Secondary
- To compare the safety of cetuximab reintroduction, in terms of frequency of grade 3-4 allergic reactions in these patients.
- To compare improvement in disease control (i.e., complete response plus partial response plus stable disease) at 24 weeks in patients treated with these regimens.
- To compare overall and progression-free survival of patients treated with these regimens.
- To compare response rates at 12, 24, and 36 weeks in patients treated with these regimens.
- To compare toxicity of these regimens in these patients.
