Surgical treatment of pleural mesothelioma.

From 1939 through 1981, 170 patients were seen and treated for pleural mesothelioma. Twenty-one tumors were benign, 47 were fibrosarcomatous, and 102 were epithelioma. Resection was the main mode of treatment in benign and fibrosarcomatous mesothelioma. Treatment of diffuse epithelial mesothelioma presented the greatest challenge. Surgical therapy, radiation therapy, and chemotherapy were used in combination in these patients. The review of our patients treated prior to 1972 had shown no benefit from including pulmonary resection in the surgical treatment of these tumors. Since then, all patients with diffuse mesothelioma were treated by pleurectomy without pulmonary resection. Both internal and external radiation therapy were also used to enhance local control. Forty-nine percent of patients with epithelial mesothelioma lived 1 year. The median survival in patients whose disease was controlled by these methods was 21 months. Despite the poor prognosis in malignant mesothelioma, better controlled by these methods was 21 months. Despite the poor prognosis in malignant mesothelioma, better survival was achieved when the treatment included operation combined with radiation and chemotherapy.
