AB Background/Aim: The aim of the study was to determine outcomes and overall survival (OS) in patients undergoing cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) for malignant peritoneal mesothelioma (MPM). Patients and Methods: This was a retrospective cohort study from a prospectively maintained database of patients that underwent CRS/HIPEC for MPM from April 1999 to December 2021. Results: A total of 81 patients were identified with MPM. Median OS was 53 months with a 1-, 3- and 5-year OS of 76%, 55% and 49% respectively. Multivariate analysis identified lymph node status, PCI and CC score as statistically significant prognostic factors that impact survival. Median OS for PCI 0-20 was 103 months vs. 33 months for PCI 21-39 (p=0.005). Median OS for CC0, CC1 and CC2 were 104, 30 and 2.7 months respectively (p<0.001). Hazard ratio for node-positive disease over node-negative was 2.14 (95% CI=1.07-4.31, p<0.033). Grade III/IV complication rate was 43.2% and mortality 4.9%. Conclusion: CRS/HIPEC remains the gold standard for treating patients with MPM with excellent patient OS. Lymph node status, PCI and CC score were independent prognostic factors that affect OS.
