title: Induction chemotherapy to weekly paclitaxel concurrent with curative radiotherapy in stage IV (M0) unresectable head and neck squamous cell carcinoma: a dose escalation study.
abstract: The purpose was to determine the maximum tolerated dose (MTD) of weekly paclitaxel with concurrent, daily irradiation in patients with unresectable head and neck squamous cell carcinoma previously submitted to induction chemotherapy. Patients with stage IV, and unresectable tumor and/or node/s were enrolled. Nine male patients were submitted to a course of paclitaxel 175 mg/m2 day 1 and cisplatin 75 mg/m2 day 2 given every 3 weeks for three courses. Curative radiotherapy (RT) started 3 weeks after the last cycle of chemotherapy with the goal of delivering a total dose of 66-70 Gy. During RT weekly paclitaxel was administered for 6 courses if feasible; paclitaxel was given according to a dose escalation schema in cohorts of three patients. Dose level A, 30 mg/m2; dose level B, 40 mg/m2; dose level C, 50 mg/m2. During weekly paclitaxel the major toxicity was mucositis that required a treatment break in two of three patients in dose level C; mucositis grade 4 required interruption of paclitaxel administration in all these patients. RT can be given in a continuous fashion with weekly paclitaxel after induction chemotherapy. The MTD of weekly paclitaxel was 40 mg/m2.
