Background: There is conflicting evidence regarding the survival benefit of interval debulking surgery (IDS) compared with conventional treatment with primary debulking surgery (PDS) in women with advanced epithelial ovarian cancer (EOC). Objectives: We compared the survivals following PDS followed by adjuvant chemotherapy (ACT) versus IDS after neoadjuvant chemotherapy (NACT) in women with advanced EOC at the gynecological oncology unit of a tertiary referral center in Lagos, Southwest Nigeria. Methods: The data of 126 women with advanced EOC who had standard treatment with either PDS and ACT or NACT and IDS between January 2008 and December 2017 were analyzed. Kaplan–Meier estimates of progression-free (PFS) and overall survival (OS) time stratified by the types of upfront debulking surgery were calculated and compared by employing the log-rank test statistics. Cox proportional hazard models were then used to estimate hazard ratios (HRs) of the association between the type of surgical debulking and survivals while adjusting for all necessary covariates. Results: We recorded no statistically significant differences in PFS (adjusted HR = 0.78, 95% confidence interval [CI] = 0.49–1.22, p = 0.282) and OS (adjusted HR = 0.81, 95% CI = 0.45–1.47, p = 0.491) between IDS and PDS among women with advanced EOC. Conclusions: There is a need for a larger prospective multicenter study to further compare the impact of upfront surgical debulking types on the survival of women with advanced EOC in our setting. In the meantime, giving interval debulking surgery after a few courses of NACT should be an acceptable standard of care for women with advanced EOC. [ABSTRACT FROM AUTHOR]
