Combined Chemotherapy in Pleurectomized Malignant Pleural Mesothelioma Patients

Abstract A phase II clinical trial of 20 cancer patients who presented with malignant pleural mesothelioma (MPM) between November 1991 and April 1993 was conducted. Of the histologically proven cases, 16 (80%) were epitheloid and 4 (20%) were mixed type MPM. Patients were treated with mitomycin C, cisplatin, and alpha interferon after pleurectomy. Our schedule consisted of 10 mg/m2 mitomycin C i.v. infusion, 50 mg/m2 cisplatin i.v. infusion, 10 mil Ur-alpha interferon i.m. and 10 mil Uralpha interferon i.v. infusion on the first day of treatment. Patients were given a mean of 4.5 chemotherapy cycles (range: 2-6).None of the patients showed complete or partial response. Stable disease was observed in 15 patients, while 5 patients had progressive courses. The overall median survival time after chemotherapy was 12 months (range: 3-31 months). Median survival after chemotherapy was 15 months (range: 4-31 months) in the stable disease group (n:15, 75%), and 5 months (range: 3-13 months) in progressive cases (n...
