Background: The most common sites of malignant mesothelioma are the pleura [ i.e., pleural mesothelioma ] and peritoneum [ i.e., peritoneal mesothelioma ], but little is known about the incidence, prognosis, or treatment of patients with disease in both cavities…. Despite limitations, this investigation is the only study to broadly examine outcomes for patients with malignant mesothelioma in both the pleural and peritoneal cavities.
Methods: This study retrospectively examined 50 patients with both pleural and peritoneal mesothelioma treated with the intent to prolong survival. The primary end point was overall survival from the initial operative intervention.
Results: The median overall survival was 33.9 months from the initial intervention….
Conclusions: Well-selected patients with both pleural and peritoneal mesothelioma have a survival benefit over palliative treatment that is comparable with that seen in single-cavity disease. The presence of disease in both cavities is not a contraindication to multimodality treatment aimed at prolonging survival….
