The Eastern Cooperative Oncology Group has conducted a retrospective review of their experience of 96 patients with a tissue diagnosis of malignant mesothelioma treated between 1972 and 1980 on four separate sarcoma chemotherapy protocols. Thirty-two of the 96 patients were diagnosed and treated in South Africa. There were 75 males and 21 females with an age range of 27 to 78 with a median of 58.1 years. All, except for 28 patients, had some form of prior therapy. The median time from the onset of symptoms to diagnosis was 12 weeks; from the diagnosis to randomization was 15.1 weeks. Only 12 of the 96 patients demonstrated an objective regression. The responses were 7/51 on Adriamycin with 2 complete responses (complete responses--38 weeks and 52 weeks), 2/24 on Adriamycin combinations, 2/7 on cycloleucine, 1/3 on bleomycin, and 0/10 on non-Adriamycin combinations. Only 1/28 responded to a cross-over therapy (Adriamycin). The median survival from the start of protocol chemotherapy was 7.4 months and 7.5 months for Adriamycin treated patients. The median survival for responders was 29.9 months, compared to 6.3 months for nonresponders. The median survival for this entire series from the time of first symptoms was 15.2 months. The median survival for the 7 patients with abdominal mesothelioma was 12 weeks. There was a slight improvement in survival for the South Africans as compared to the Americans. Malignant mesothelioma in this series, was a rapidly lethal, nonresponsive disease whose treatment will require new therapies.
