Long-term survival in peritoneal mesothelioma the role of radiotherapy and combined modality treatment

Ten patients with peritoneal mesothelioma were treated at the Joint Center for Radiation Therapy between 1968 and 1985. Six of the ten patients remained free of disease at 19+ to 78+ months after diagnosis. The six patients received sequential surgical debulking, combination chemotherapy, and whole-abdomen irradiation. Four patients not treated with this multimodality approach died with disease. This approach may have an impact on the natural course of peritoneal mesothelioma, and warrants further study.
