Phase 1 study of paclitaxel, cisplatin, and 5-fluorouracil (TCF) in patients with advanced gastric cancer
14134 Background: Paclitaxel is effective against gastric cancer with serosal involvement and/or peritoneal dissemination. Combination of cisplatin and 5-fluorouracil is also active against advanced gastric cancer. Therefore, we designed a phase I trial of a combination of paclitaxel, cisplatin and 5-fluorouracil (TCF) to explore potential synergistic effect. Methods: Eligible patients had metastatic or unresectable gastric cancer with up to 1 prior chemotherapy regimen. The fixed dose of cisplatin 25 mg/m2 and paclitaxel 80 mg/m2 with escalation dose of 5-fluorouracil from 300 mg/m2 to a maximum of 600 mg/m2 on days 1, 8 and 15 of a 28 day schedule were administered. MTD and anti-tumor activity were evaluated. Results: No grade 3 or 4 toxicities at least possibly related to the treatments resulting in DLT were observed on every dose level. The clinical effects were determined in 3 patients with measurable lesions out of 7 cases. There were 2 partial responses, and disease stabilization was seen in one patient. Conclusions: Combination of paclitaxel, cisplatin and 5-fluorouracil (TCF) is considered to be feasible, well tolerated and active in patients with advanced gastric cancer and warrants further examination in a phase II trial.
