[Cisplatin, peplomycin, mitomycin C, and vincristine combination chemotherapy of non-small cell carcinoma of the lung].

Twenty patients with unresectable non-small cell lung cancer were treated with a combination chemotherapy of cisplatin (30 mg/body i.v., days 1-5), peplomycin (5 or 8 mg/body continuous infusion, days 1-5), mitomycin C (4 mg/body i.v., day 1), and vincristine (2 mg/body i.v., day 1), of 15 patients evaluable for response (9 with squamous cell carcinoma, 2 with adenocarcinoma, nd 4 with large cell carcinoma), the overall response rate was 46.7% with 7 partial responses. The median survival period for responders. Toxicity included hair loss, nausea and/or vomiting, mild to moderate myelosuppression, nephrotoxicity, and pulmonary toxicity, all of which was manageable. This four-drug combination chemotherapy is concluded to be effective for non-small cell lung cancer.
