Abstract

OBJECTIVE:

This dose-escalation study of a combination of docetaxel, cisplatin and S-1 investigated the dose-limiting toxicity (DLT), maximum-tolerated dose (MTD), recommended dose (RD) and antitumor activity in advanced gastric cancer.

PATIENTS AND METHODS:

Patients received docetaxel (40 mg/m(2)), cisplatin (DIV on day 1) and S-1 (40 mg/m(2) p.o., twice daily, on days 1-14 every 28 days). The starting dose of cisplatin was 60 mg/m(2) (level 1); the dose was escalated to 70 (level 2) and 80 mg/m(2) (level 3) in a stepwise fashion.

RESULTS:

Fourteen patients were enrolled. The MTD of cisplatin was 80 mg/m(2) (level 3). DLT was grade 3 diarrhea, febrile neutropenia and delayed resumption of treatment. The RD of cisplatin was considered to be 70 mg/m(2) (level 2). DLT was liver dysfunction, occurring in only 1 patient at level 2. The response rate was 69.2% (9/13).

CONCLUSIONS:

For combined treatment with docetaxel, cisplatin and S-1 in patients with advanced gastric cancer, RD were docetaxel 40 mg/m(2), cisplatin 70 mg/m(2) and S-1 80 mg/m(2)/day. This regimen yields a high rate of tumor response and can be administered safely. Phase II studies of this regimen are under way.
