Combination chemotherapy of squamous cell carcinoma of the bronchus with cisplatinum and bleomycin followed by radiotherapy: results of a pilot study.

Thirteen patients were entered into an uncontrolled pilot study to investigate the response to, and toxicity of, a combination of cisplatinum (20 mg/m2) and bleomycin (6 mg/m2) infused daily for 5 days and repeated every 21 days up to a maximum of 4 cycles, in the treatment of squamous cell carcinoma of the bronchus. This regimen was subsequently followed by a split course of local irradiation. All patients have been followed to death. Six patients showed a partial response to chemotherapy while 7 showed no response or progressive disease. The median survival was 5 months. The median survival of the responders was 15 months and that of the nonresponders 3 months. Two patients developed the syndrome of inappropriate antidiuretic hormone secretion from which one died. The longest survivor, who died 26 months after the commencement of chemotherapy, had severe mediastinal and pulmonary fibrosis.
