Carboplatin with weekly docetaxel and ifosfamide in advanced head and neck cancers: a phase I Brown University Oncology Group dose escalation study (HN-93).

PURPOSE: A phase I study was performed to determine the maximally tolerated dose of carboplatin, ifosfamide, and docetaxel in advanced head and neck cancers. METHODS: Carboplatin (week 1) was administered with weekly docetaxel and ifosfamide for 3 weeks in an every 4-week cycle. Restaging was done after two cycles, while dose level escalation was done in cohorts of three patients. RESULTS: Fifteen patients (recurrent/metastatic disease, n = 8; bulky locally advanced disease, n = 7) were enrolled. No dose-limiting toxicities were observed. Toxicities included grade 3 neutropenia and anemia (n = 2, each), and grade 2 thrombocytopenia (n = 3). The final level of carboplatin AUC = 6 (week 1) with docetaxel 30 mg/m(2) per week and ifosfamide 1,000 mg/m(2) per week was chosen for further evaluation. CONCLUSIONS: This novel regimen of carboplatin with weekly docetaxel and ifosfamide has a favorable toxicity profile and is active in this setting. Phase II study results are awaited.
