[Experience of cytoreduction with peritonectomy and hyperthermic intraperitoneal chemotherapy in ovarian cancer].

Background: Currently, epithelial ovarian cancer is diagnosed in advanced stages (EC IIIC) in 75-80% of cases worldwide. In this group of patients treatment with neoadjuvant chemotherapy is started, followed by interval cytoreduction of residual disease and even require peritonectomy with application of hyperthermic intraperitoneal chemotherapy (HIPEC).

Objective: To identify the overall survival and progression-free survival associated with peritonectomy, in patients with peritoneal carcinomatosis secondary to ovarian cancer treated in the oncology gynecology service from January 2009 to January 2019 at the UMAE Hospital de Oncología Centro Médico Nacional Siglo XXI.

Material and methods: Observational, descriptive, cross-sectional, retrospective study, information was obtained from the clinical file of patients treated with peritonectomy with the use of hyperthermic intraperitoneal chemotherapy in the gynecological oncology service from January 2009 to January 2019 at the UMAE Hospital de Oncología Centro Médico Nacional Siglo XXI.

Results: Information was obtained from a total of 36 patients (n=100%), 36.1% received intraperitoneal chemotherapy and 63.8% underwent cytoreduction without the application of intraoperative chemotherapy. The most frequently used drug was cisplatin followed by mitomycin. There was no statistical significance when comparing both groups, however there was a trend in favor of the use of intraoperative chemotherapy by obtaining a greater number of months in terms of overall survival.

Conclusion: Peritonectomy with hyperthermic intraperitoneal chemotherapy is an option in selected patients with advanced stage ovarian cancer in primary and recurrent surgery, as well as in patients with platinum-resistant ovarian cancer.
