Concurrent daily cisplatin and radiotherapy in locally advanced squamous carcinoma of the head-and-neck and bronchus

In order to exploit the cytotoxic and radiosensitising actions of cis-platinum, 35 patients have been treated with locally advanced squamous cell carcinoma of the bronchus or head-and-neck. Each patient underwent radical irradiation (60 Gy/30 fractions over 6 weeks) with daily low-dose intravenous cisplatin (10 mg absolute dose per day) administered within 30 min of each daily radiation fraction. Total dose of cisplatin was 300 mg over 6 weeks. Although treatment was complicated by nausea in almost all patients and transient renal dysfunction in the majority, 27 patients completed treatment and renal function returned to normal or near normal in almost all cases. There was no obvious enhancement of pulmonary or skin toxicity, beyond what would have been expected from treatment with radical radiotherapy alone. There were two treatment-related deaths from renal failure. The response rate was high: all patients achieved at least a partial response, and in head-and-neck sites, there were nine complete responders and seven partial responders. Of the initial 35 patients, of whom all but two had advanced inoperable disease, 11 have died and 21 remain in continuous remission 8-120 weeks from the start of treatment (median 55 weeks). 21 refs
