简要总结
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.
PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy in treating patients who have metastatic colorectal cancer.
详细描述
OBJECTIVES:
- Determine the response rate of patients with metastatic colorectal carcinoma treated with O6-benzylguanine and carmustine.
- Evaluate tumor tissue biochemical and immunohistochemical predictors of response in patients treated with this regimen.
- Correlate carcinoembryonic antigen levels in the peripheral blood with response in patients treated with this regimen.
OUTLINE: This is a multicenter study.
Patients receive O6-benzylguanine (BG) IV over 1 hour and carmustine IV over 1 hour (beginning 1 hour after completion of BG infusion) on day 1. Treatment continues every 6 weeks in the absence of disease progression or unacceptable toxicity.
Patients are followed every 3 months.
