A patient with large cell carcinoma of the lung with multiple intrapulmonary metastases has been treated with three courses of cisplatin-based polychemotherapy (cisplatin, adriamycin and peplomycin). He experienced nausea, vomiting, alopecia, and bone marrow suppression as side effects, which proved to be mild, that he tolerated well. A complete response was obtained, and he has been free of disease for more than three years.
