Abstract

Study Objective: To compare outcomes of advanced ovarian cancer patients who had minimally invasive surgery (MIS) with outcomes of advanced ovarian cancer patients who had laparotomy for interval cytoreduction after neoadjuvant chemotherapy (NACT). Design: Retrospective cohort study (Canadian Task Force classification II-2). Setting: One large teaching hospital with a tertiary referral function for gynecologic oncology and MIS. Patients: All consecutive patients with stages III to IV epithelial ovarian, tubal, or peritoneal cancer who underwent MIS or laparotomy for interval cytoreduction after at least 1 NACT cycle from 2006 to 2017 at 1 institution. Interventions: Patients underwent either MIS or laparotomy for interval cytoreduction after at least 1 cycle of NACT. Measurements and Main Results: Medical records were reviewed and data abstracted and analyzed. Survival was estimated by the Kaplan-Meier method, and outcomes were compared with Fisher's exact test, Student's t test, Wilcoxon rank sum test, and the log-rank test. In total, 157 assessable patients underwent interval cytoreductive surgery through MIS (n = 53) or laparotomy (n = 104). MIS was completed without conversion in 44 of 53 patients (83%), of whom 20 required a hand port and/or mini-laparotomy. R-zero and optimal resections were achieved in 60.4% and 96.3% of MIS patients respectively, compared with 42.3% and 82.7% of laparotomy patients (p = .02). MIS patients had lower estimated blood loss (EBL; 156 vs 278 mL, p <.001), fewer intraoperative transfusions (2% vs 17%, p = .006), and shorter hospital stay (3.0 vs 5.7 days, p < .001). Operative time was longer (171 vs 150 minutes, p = .007), but complications, intensive care unit stay, readmission, median progression-free survival (27 vs 29 months, p = .45), and median overall survival (37 vs 35 months, p = .74) were similar. Conclusion: MIS is feasible and effective for interval cytoreduction after NACT in advanced ovarian cancer patients. MIS is associated with less EBL, lower transfusion rate, and shorter length of hospital stay with no difference in patient outcomes.
