Mitomycin, ifosfamide and cisplatin in non-small-cell lung cancer

Chemotherapy with mitomycin C, ifosfamide and cisplatin (MIC) is reported to produce responses of 56% and 69% in inoperable non-small-cell lung cancer (NSCLC). We evaluated the regimen in 45 similar patients who received up to six courses of 6 mg/m2 mitomycin C, 3 g/m2 ifosfamide, and 50 mg/m2 cisplatin every 3 weeks. In all, 18 patients had limited disease (LD) and 27 had extensive disease (ED). A total of 18 patients responded (40%), 9/18 with LD and 9/27 with ED; there were 4 complete responders. The median duration of response was 25 weeks, and median survival was 32 weeks (range, 2-96 weeks). Toxicity was moderate. Nausea and vomiting were controlled with i.v. dexamethasone and high-dose metoclopramide. Other toxicities included myelosuppression and alopecia. This study confirms that MIC is one of the most active regimens for treatment of NSCLC, with acceptable toxicity.
