A Cytoreductive Surgery plus Hyperthermic Intraperitoneal Chemotherapy in Primary Advanced Ovarian Cancer: The First Reported Pilot Experience from Saudi Arabia.

Background: Around two thirds of patients with ovarian cancer present to clinical attention with advanced-stage disease in the form of peritoneal carcinomatosis (PC) or distant metastasis, which is correlated with a poor fiveyear overall survival (OS) of less than 20%. The addition of hyperthermic intraperitoneal chemotherapy (HIPEC) to cytoreductive surgery (CRS) has been depicted to offer survival benefits in patients with PC arising from primary advanced ovarian cancer. However, no similar study was conducted from Saudi Arabia, specifically, or the Gulf region, generally.
