title: [Phase I/II clinical trial of induction chemotherapy with nedaplatin (CDGP), docetaxel (DOC) and 5-fluorouracil (5-FU) for squamous cell carcinoma of head and neck].
abstract: In a phase I study, we determined the maximum tolerated dose (MTD) and the recommended dose (RD) of nedaplatin (CDGP) in combination chemotherapy with Docetaxel (DOC) and 5-fluorouracil (5-FU) for treatment of carcinoma of the head and neck. Then, in a phase II study, we examined the efficacy and safety of the RD of chemotherapy. Fresh patients with squamous cell carcinoma of the head and neck were enrolled in the study. The dosage of chemotherapy was as follows: DOC 60 mg/m(2) on day 1 by infusion over 2 hours; CDGP 20-30 mg/m(2)/day on day 1 to 5 by infusion over 1 hour, and 5-FU 600 mg/m(2)/day on day 1 to 5 by 5 days continuous infusion. For CDGP, an initial dose level was set at 20 mg/m(2), and 3 patients were enrolled for each level of dose escalation. The DLT was defined here as grade 4 neutropenia or grade> or =3 non-hematotoxic reactions. The dose at which DLT was observed in overall 33% cases was taken as MTD. The RD for phase II study was estimated to be DOC 60 mg/m(2), CDGP 20 mg/m(2)/day, 5-FU 600 mg/m(2)/day. Forty patients were enrolled in the phase II study. DLT of neutropenia was noted in 2 of 38 cases. DLT of non-hematotoxic reactions was found in less than 33% of the cases; 17 cases showed CR, and 12 cases showed PR. The response rate was 76.3%. The overall response rate in histological assessment was 55.3%. The combination chemotherapy with Low-Divided Dose of CDGP, DOC and 5-FU was suggested to be safe and effective.
