Preventing recurrence of diffuse malignant peritoneal mesothelioma

Introduction: Diffuse malignant peritoneal mesothelioma (DMPM) is an aggressive malignancy with a poor prognosis when treated with systemic therapy. Cytoreductive surgery (CRS) with intraperitoneal chemotherapy (IPC) is considered the best therapy in DMPM, but a high risk of locoregional recurrence remains. Areas covered: This review describes patient selection and operative goals with CRS and IPC, the reported outcomes with this approach, and the data supporting platinum-based IPC. We assess the pharmacokinetics supporting the use of dwell IPC. We outline clinical, imaging and laboratory surveillance for recurrence. In addition, we highlight the role of re-operation, both as a planned second procedure and in the context of disease recurrence. Literature review was performed via Medline search. Expert commentary: CRS/IPC offers survival benefit in selected patients with DMPM, but given the high rate of recurrence, close surveillance is needed post-operatively. Strategies to prevent and treat recurrent disease include dwell IPC and second CRS/IPC.
