Cytoreductive Surgery and Hyperthermic Intraoperative Chemotherapy for Management of Peritoneal Carcinomatosis.

BACKGROUND: Treatment of peritoneal metastases has gained interest among oncologic communities around the world. Cytoreductive surgery (CRS) and hyperthermic intraoperative chemotherapy (HIPEC) have come to be the treatment of choice for selected patients with peritoneal carcinomatosis (PC) in recent years. Prior to HIPEC, patients were treated with palliative support and only guaranteed a few months to live. We reviewed our first 30 patients who underwent CRS and HIPEC. The aim of the study was assessment of the patients' survival, morbidity, and mortality rate and identifying prognostic factors of patients treated with CRS and HIPEC.

METHODS: In this cross-sectional study, data were retrospectively collected from 45 patients (15 men and 30 women) who underwent CRS and HIPEC between December 2008 and October 2016, at Nemaazi educational hospital and Shiraz central hospital of Shiraz University of Medical Sciences. Peri-operative and regular follow-up data on survival and complications were gathered and analyzed to identify their prognostic value for survival.

RESULTS: The mean age of the patients was 49.7±16.46 years. The participants in this study consisted of 19 females (63.3%) and 11 males (36.7%). The most common primary tumor was ovarian cancer (30.1%). A completeness of cytoreduction score of CC0/CC1 was obtained in 80% of patients operated on with curative intent. The overall mortality rate was 20%. The 1- and 4-year overall survival (OS) were 89% and 54%, respectively.

CONCLUSION: CRS and HIPEC are most successful in treatment of selected patients. Development of complete resection with CRS in these 8 years and good OS in our patients encourage us to continue the procedure with all its difficulties and cost.
