Cytoreductive surgery and intraperitoneal hyperthermic chemotherapy for malignant peritoneal mesothelioma

OBJECTIVES: The aim of this study is to evaluate the results of treatment of diffuse malignant peritoneal mesothelioma (DMPM) by cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) at a single center. METHODS: We conducted a retrospective single-center observational cohort study of consecutive patients with DMPM treated by CRS-HIPEC at the Department of Surgery I of the University Hospital in Olomouc, Czech Republic. RESULTS: Data on a total of 16 patients were processed. The study group of 16 patients had six (37.5 %) women. The mean age was approximately 62 years. Complete cytoreduction was achieved in all patients (100 %) (CC0: 75 %, CC1: 25 %). All patients underwent a closed form of HIPEC with cisplatin and doxorubicin for 90 min. The mean hospital stay was 13.5 days, including 4.38 days in the ICU (13.5 +/- 5.07 and 4.38 +/- 1.49, respectively). Major postoperative complications (CD grades 3-4) occurred in four patients (25 %). In-hospital mortality was 6.25 %. In the study group, the median overall survival was 20 months, and the median disease-free survival was 10.3 months. CONCLUSIONS: Under the conditions at our specialized center, CRS-HIPEC is considered as an effective, affordable, and safe therapy with OS, DFS, morbidity, and mortality rates comparable to those reported in the literature (Tab. 5, Fig. 2, Ref. 28).
