OBJECTIVE: Although standard treatment for advanced epithelial ovarian cancer 
(EOC) consists of surgical debulking and intravenous platinum- and taxane-based 
chemotherapy, favorable oncological outcomes have been recently reported with 
the use of cytoreductive surgery (CRS) and hyperthermic intraperitoneal 
chemotherapy (HIPEC). The aim of the study was to analyze feasibility and 
results of CRS and HIPEC in patients with advanced EOC.
MATERIALS/METHODS: This is an open, prospective phase 2 study including patients 
with primary or recurrent peritoneal carcinomatosis due to EOC. Thirty-nine 
patients with a mean (SD) age of 57.3 (9.7) years (range, 34-74 years) were 
included between September 2005 and December 2009. Thirty patients (77%) had 
recurrent EOC and 9 (23%) had primary EOC.
RESULTS: For HIPEC, cisplatin and paclitaxel were used for 11 patients (28%), 
cisplatin and doxorubicin for 26 patients (66%), paclitaxel and doxorubicin for 
1 patient (3%), and doxorubicin alone for 1 patient (3%). The median 
intra-abdominal outflow temperature was 41.5°C. The mean peritoneal cancer index 
(PCI) was 11.1 (range, 1-28); and according to the intraoperative tumor extent, 
the tumor volume was classified as low (PCI <15) or high (PCI ≥15) in 27 
patients (69%) and 12 patients (31%), respectively. Microscopically complete 
cytoreduction was achieved for 35 patients (90%), macroscopic cytoreduction was 
achieved for 3 patients (7%), and a gross tumor debulking was performed for 1 
patient (3%). Mean hospital stay was 23.8 days. Postoperative complications 
occurred in 7 patients (18%), and reoperations in 3 patients (8%). There was one 
postoperative death. Recurrence was seen in 23 patients (59%) with a mean 
recurrence time of 14.4 months (range, 1-49 months).
CONCLUSIONS: Hyperthermic intraperitoneal chemotherapy after extensive CRS for 
advanced EOC is feasible with acceptable morbidity and mortality. Complete 
cytoreduction may improve survival in highly selected patients. Additional 
follow-up and further studies are needed to determine the effects of HIPEC on 
survival.
