Phase-II study of vindesine and hexamethylmelamine in patients with relapsing small cell carcinoma of the lung.

Twenty-five patients with measurable small cell lung cancer relapsing after first-line chemotherapy were treated with vindesine 3 mg/m2 IV on days 1 and 8 and hexamethylmelamine 100 mg/m2 PO on days 1-14, repeated every 3 weeks. Among 18 fully evaluable patients there was 1 partial remission lasting for 111 days. Two patients had disease stabilization for 127 and 152 days, respectively. Fifteen patients had disease progression. The treatment was well tolerated, myelosuppression being the major side-effect.
