Purpose: This multi-institutional registry study evaluated cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) for diffuse malignant peritoneal mesothelioma (DMPM) VSports手机版. .

Patients and methods: A multi-institutional data registry that included 405 patients with DMPM treated by a uniform approach that used CRS and HIPEC was established. The primary end point was overall survival V体育安卓版. The secondary end point was evaluation of prognostic variables for overall survival. .

Results: Follow-up was complete in 401 patients (99%). The median follow-up period for the patients who were alive was 33 months (range, 1 to 235 months). The mean age was 50 years (standard deviation [SD], 14 years). Three hundred eighteen patients (79%) had epithelial tumors. Twenty-five patients (6%) had positive lymph nodes. The mean peritoneal cancer index was 20. One hundred eighty-seven patients (46%) had complete or near-complete cytoreduction V体育ios版. Three hundred seventy-two patients (92%) received HIPEC. One hundred twenty-seven patients (31%) had grades 3 to 4 complications. Nine patients (2%) died perioperatively. The mean length of hospital stay was 22 days (SD, 15 days). The overall median survival was 53 months (1 to 235 months), and 3- and 5-year survival rates were 60% and 47%, respectively. Four prognostic factors were independently associated with improved survival in the multivariate analysis: epithelial subtype (P < . 001), absence of lymph node metastasis (P < . 001), completeness of cytoreduction scores of CC-0 or CC-1 (P < . 001), and HIPEC (P = . 002). .

Conclusion: The data suggest that CRS combined with HIPEC achieved prolonged survival in selected patients with DMPM VSports最新版本. .
