Malignant peritoneal mesothelioma is a rare disease, with approximately 800 new patients per year in the United States. Its natural history is defined by progression restricted to the peritoneal space. In the past, patients with this disease had a limited lifespan of approximately 1 year. Numerous single-institution studies as well as a systematic review have reported median survival of 3 to 5 years with a combination of cytoreductive surgery and hyperthermic perioperative chemotherapy. These markedly improved survival statistics were achieved in experienced centers with 1% mortality and 20% morbidity rates. Data have shown that knowledgeable patient selection is required to prevent patients unlikely to benefit from undergoing these interventions. The conclusion is that patients with peritoneal mesothelioma can experience long-term progression-free survival or significant palliation with cytoreductive surgery plus hyperthermic perioperative chemotherapy. This management plan should be considered the standard of care for properly selected patients with malignant peritoneal mesothelioma at experienced centers around the world.
