Abstract

Objective: Data regarding the effect of post-partum bilateral tubal ligation (BTL) on future risk for ovarian cancer (OC) is lacking. In the current study, we aimed to evaluate the effect of BTL during cesarean delivery (CD) on the long-term risk for OC. Study design: A population-based cohort analysis of women above the age of 35 that underwent CD in their last delivery, comparing the long-term risk for OC between patients that had a Pomeroy excisional BTL and those that did not. OC diagnosis was pre-defined based on ICD-9 codes. Procedures occurred between the years 1991–2017. Kaplan–Meier survival curve was used to compare the cumulative incidence of OC over time and Cox proportional hazards model was constructed to control for confounders. Results: During the study period 13,124 women met the inclusion criteria; 9438 (71.9%) of which had only CD and 3686 (28.1%) underwent CD with BTL. Despite the significantly higher incidence of maternal factors that might increase the long-term risk for OC in the BTL group (advanced maternal age, obesity, hypertensive diseases during pregnancy and diabetes mellitus), the cumulative incidence of OC cases was not significantly different between the two groups (Log-rank test p = 0.199). Likewise, when performing a Cox regression model controlling for maternal age, obesity, hypertensive diseases and diabetes, OC risk was not significantly different between the groups (adjusted HR 2.36, 95% CI 0.73–7.62; p = 0.149). Conclusion: Despite an increased incidence of known risk factors for OC, patients that underwent BTL during CD did not have increased long-term risk for OC.
