Phase II study with mitomycin, ifosfamide and carboplatin in inoperable non-small cell lung cancer.
In a phase II study of non-small cell lung cancer a new chemotherapy combination of mitomycin 6 mg/m2 intravenously on day 1, carboplatin 400 mg/m2 intravenously on day 1 and ifosfamide with mesna 5 g/m2 intravenously over 24 hours on day 1 was evaluated. A maximum of four chemotherapy cycles was given at intervals of 4 weeks to 34 patients with progressive, inoperable disease. 1 complete and 10 partial remissions were documented, the overall response rate being 32.4%. In a further 13 patients (38.2%) the previously progressing tumours remained stable for at least 6 weeks. The median time to progression for responding patients was 184 days. The median survival time for the whole group has not yet been reached at 293 days. A considerable but easily manageable myelosuppression was the principal toxicity despite a "no dose reduction" policy. Indeed, the dose intensity of the chemotherapy actually given was extremely close (97%) to that intended on protocol. In conclusion, the regimen is active in patients with advanced non-small cell lung cancer but requires regular haematological monitoring to prevent morbidity resulting from myelotoxicity.
