Complete Laparoscopic Interval Debulking Surgery for Advanced Ovarian Cancer Achieves Similar Survival Outcomes to Open Approach: A Propensity-Matched Study.

To assess the laparoscopic interval debulking surgery (IDS) outcomes compared to laparotomy, by analyzing the overall survival (OS) and the progression free survival (PFS), as well as the intra- and post-operative morbidity. In this retrospective propensity-score-matched cohort study, all patients with stage III or IV FIGO (International Federation of Gynecology and Obstetrics) serous ovarian cancer, undergoing complete IDS after neoadjuvant chemotherapy, from January 1st of 2009 to June 1st 2019, were included. Thirty-seven patients were included in the laparoscopy group and 40 in the laparotomy group. There was no significant difference in terms of median OS between laparoscopy and laparotomy (23.1 months [95% CI 15.7-29.7] versus 26.3 months [95% CI 21.7-31.7], respectively, In carefully-selected patients with advanced ovarian cancer, complete laparoscopic interval debulking surgery achieves similar survival outcomes to open laparotomy. Therefore, laparoscopy appears as a safe alternative to laparotomy for IDS after NACT in selected patients with advanced ovarian cancer and a low burden of disease.
