Impact of ovarian preservation in women with endometrial cancer

Abstract Background Bilateral salpingo-oophorectomy (BSO) is standardly performed in the treatment of endometrial cancer. The purpose of this study was to evaluate the impact of ovarian preservation on the outcome of patients with endometrial cancer. Methods A retrospective cohort study was performed using the 2000–2010 database of endometrial cancer patients who were treated at Taipei Veterans General Hospital. Information regarding patient age, pathologic reports, and follow-up results was abstracted from medical records. Results Five hundred and twenty-nine patients were reviewed in this study. Mean age and follow-up duration were 55.7 ± 11.4 years and 37.5 ± 30.1 months, respectively. The median disease-free survival was 31.2 months (range 0.2–126.9 months). There were no significant differences in disease-free survival between stage I patients with ovarian preservation versus those with oophorectomy ( p = 0.473). In a multivariate Cox model, ovarian preservation had no effect on disease-free survival [hazard ratio (HR) = 2.72; 95% confidence interval (CI), 0.48–15.59]; however, it was not significantly related to stage and para-aortic lymph node involvement. Conclusion Ovarian preservation may be considered in premenopausal women with early-stage low-risk endometrial cancer.
