摘要

Objectives: To determine the maximum-tolerated dose (MTD) and dose-limiting toxicity (DLT) of both docetaxel and 5-fluorouracil (5-FU) when administered weekly in a regimen of docetaxel, 5-FU/leucovorin and cisplatin (DFLP) for 2 consecutive weeks every 3 weeks. Patients and Methods: A total of 31 patients with chemonaive, advanced adenocarcinoma of the stomach were enrolled in the study. Cisplatin and leucovorin dosages were fixed throughout the study at 30 and 300 mg/m2, respectively. 5-FU dosage was fixed at 1,600 mg/m2 while docetaxel was evaluated at weekly 1-hour infusion dosages of 30, 40 and 50 mg/m2 to determine the MTD. Cisplatin, 5-FU and leucovorin were administered together as a 24-hour continuous infusion following docetaxel. Weekly 5-FU dosages of 1,600, 2,000 and 2,400 mg/m2 were then evaluated after setting the docetaxel dosage at the MTD. Results: A total of 95 chemotherapy cycles were administered, with a median of three cycles per patient. The MTD of docetaxel was defined at 40 mg/m2. At a docetaxel dosage of 50 mg/m2 per week, the dose-limiting events of grade 4 febrile neutropenia and grade 3 hypomagnesemia occurred. With fixation of docetaxel to 40 mg/m2, the DLT for 5-FU was found at 2,400 mg/m2 per week. This incurred grade 4 neutropenia such that the MTD of 5-FU was defined at 2,000 mg/m2. Grade 3/4 neutropenia occurred in 14 patients (45%), with 2 patients developing febrile neutropenia. Grade 2 and 3 hypomagnesemia and hypokalemia occurred in 9 (41%) and 4 (18%) patients, respectively, of the first 22 patients treated with a 24-hour infusion of cisplatin and 5-FU/leucovorin immediately following docetaxel. Following a change in the cisplatin administration schedule to a 3-hour infusion after 5-FU/leucovorin infusion, no such complications were observed in 9 subsequently treated patients. Grade 2 diarrhea was recorded in 11 patients (35%). Grade 2/3 asthenia occurred in 9 patients (30%), which resolved after correction of electrolyte disorders. Twenty-six patients were assessable for response analysis. There were 2 (7.8%) complete and 14 (53.8%) partial responses, with the overall response rate being 61.5% (95% confidence interval, 41.5-81.6%). Responses were observed at all dose levels. Conclusion: Two consecutive weeks of DFLP infusions every 3 weeks appear to be an active regimen with a tolerable toxicity profile in advanced gastric cancer. For further phase II studies, the recommended dose for this combination is 40 mg/m2 of docetaxel and 2,000 mg/m2 of 5-FU per week. Copyright
