The purpose of this phase II study was to analyze the morbidity and mortality of cytoreductive surgery (CRS) + intraperitoneal hyperthermic perfusion (IPHP) in the treatment of peritoneal surface malignancies.


One hundred and sixty four patients (36 ovarian cancer, 32 abdominal sarcomatosis, 34 peritoneal mesothelioma, 36 pseudomyxoma peritonei, 12 gastric cancer, 8 colon adenocarcinoma and 8 from other origins) underwent 166 procedures. Two patients underwent the intervention twice due to disease relapse. The mean follow-up was 20.6 months (range: 0.4 - 91.3). The mean age was 52 years (range: 24-76). CRS was performed with peritonectomy procedures. IPHP through Closed abdominal technique was conducted with preheated (42.5 degrees) perfusate containing cisplatin+mitomycin C or cisplatin+doxorubicin for 60/90 minutes.


grade 3/4 morbidity rate was 12.0%. Some frequent post-operatory complications were intestinal fistulas (17), respiratory (5) and abdominal bleeding (4). Multivariate analysis with logistic regression model with the backward elimination method identified carcinomatosis extension (OR: 5.3, CI95%: 1.2-24.5) as the best predictor of morbidity grade 3/4. Four patients presented grade 3/4 toxicity. Operative mortality rate was 0.6%.


CRS+ IPHP presented acceptable morbidity 3/4 toxicity and mortality rates what support the need to be tested in prospective phase III clinical trial.
