摘要

Objective: To evaluate the therapeutic as well as side effects of hydroxycamptothecin (HCPT) plus FOLFOX4 regimen as salvage therapy for patients with advanced gastric cancer. Methods: A total of 19 patients with advanced gastric cancer received HCPT plus FOLFOX4 as selvage therapy, in detail, Oxaliplatin 85 mg/m2 was given intravenously on day 1, CF 200 mg/m2, 5-Fu 400 mg/m2 given in bolus immediately after CF, days 1-2; 5-Fu 600 mg/m2 given continuously after bolus for 22 h on day 1, day 2, HCPT given intravenously at dosage of 10 mg/m2 on days 1-2. Therapeutic effects were evaluated at least after two cycles of treatment. Results: 17 cases among the 19 patients were valid for response evaluation, with CR 1, PR 6, SD 4, PD 6. The response rate was 41.2%. For the 12 patients with liver metastasis, response rate of the liver foci was 50%. The main toxicities were bone marrow suppression, nausea and vomiting, and peripheral neuropathy; there were no chemotherapy-related deaths. Conclusion: The combination regimen with HCPT plus FOFLOX4 regimen was effective as salvage therapy for patients with advanced gastric cancer, with particularly high response rate for liver metastasis, and the side effects were tolerable and manageable.
