AimThe aim of this study was to investigate feasibility and toxicity of fractionated paclitaxel administration concurrently with accelerated radiotherapy in the treatment of advanced head and neck cancer.Patients And MethodsPatients with a proven histology of inoperable head and neck carcinoma were eligible for this study. Between July 1994 and August 1995, 12 patients with stage IV (UICC) tumors were treated. Patients were required to have normal end-organ function. Exclusion criteria included: age > 70 years, metastatic disease, performance status (Karnofsky < 70), major intercurrent medical disorders, and previous chemotherapy. External radiation was delivered twice a day at 1.5 Gy per fraction, specified to the reference point (ICRU 50), with a minimum interfraction interval of 6 hours. The accelerated scheme was split into 2 courses by a rest period of 9 days (including weekends) after administration of 30 Gy within 2 weeks. After 39 days a total dose of 72 Gy was reached. Paclitaxel (30 mg/m2/d) was administered as a continuous intravenous infusion over a period of 3 hours on days 1 to 5 and 29 to 33 of radiation therapy. All patients received premedication to avoid allergic reactions and circulatory monitoring was used routinely.ResultsRadiochemotherapy was completed in 10 patients with 8 complete and 2 partial remissions. Most important toxicity was a short period of neutropenia, which occurred 3 to 6 days after chemotherapy and was associated with fever in 9 cases. During paclitaxel infusion there was a significant but clinically not relevant increase in blood pressure and a decrease in heart rate. No acute cardiac effects occurred and no hypersensitivity reaction was seen.ConclusionsThis regimen demonstrates a high activity in locally advanced head and neck cancer. Neutropenia associated with fever was the major dose limiting toxicity.
