Vindesine in bronchogenic carcinoma: a phase II trial.

Twenty-seven patients with advanced bronchogenic carcinoma were treated with vindesine, 3 mg/m2/week. Twenty-three patients were evaluable for response. Two of six patients with small-cell carcinoma and one of 17 patients with non-small-cell carcinoma had partial responses. Two other patients with non-small-cell carcinoma had minor responses. The duration of the responses was 2-4 months. Neurologic toxicity occurred in 14 patients and was mild except in two patients. There was a median hemoglobin fall of 2.2 g/dl and a median leukocyte nadir of 2800/microliter during vindesine therapy. Thrombocytopenia occurred in 2 patients and mild thrombocytosis occurred in 10 patients. Seven patients experienced phlebitis or cellulitis at the site of drug administration which could be prevented with small doses of intravenous methylprednisolone. These results suggest that vindesine is well tolerated and possesses some activity in patients with previously treated bronchogenic carcinoma.
