15. A Phase II study of PCF chemotherapy combined with surgical treatment of late gastric cancer

To investigate the efficacy and safety of PCF chemotherapy combined with surgery in the treatment of late-stage gastric cancer.From July 2008 to February 2011, 72 cases of late-stage gastric cancer that could not be treated with R0 resection were treated prospectively. Patients received 2-4 cycles of paclitaxel plus cisplatin and 5-fluorouracil (PCF regimen) chemotherapy followed by cytoreductive surgery for the primary and metastatic tumors and another 2-4 cycles of PCF chemotherapy post-operatively. The treatment completion rate, patient tolerance and overall survival time were analyzed.There was one perioperative death. The overall response rate (complete and partial response) was 72.2%. Fifty patients (69.4%) completed chemotherapy and surgical resection as planned and 42 (58.3%) cases had R0 resection. The median survival time was 23.5 months (95% CI: 15.8-31.2 months). One-year and 2-year survival rates were 67.0% and 47.0%. The survival time of patients with surgical resection was much longer than that of the non-surgery group (30.2 vs. 8.9 months) (P < 0.01). The survival time of local advanced group was 30.3 months, and was significantly longer than 17.6 months of the distant metastasis group (P < 0.01); however, it had no significant difference compared to 28.2 months of the distant metastasis group with R0 resection.PCF chemotherapy combined with surgical resection were safe and effective, and can make survival benefits for some late-stage gastric cancer patients.
