Objective In 2018, evidence-based surgical guidelines were introduced to identify appropriate patients with low-grade endometrioid endometrial cancer for ovarian conservation. We sought to identify trends and demographic shifts associated with guideline implementation.
Methods We identified women treated for endometrioid endometrial cancer at our institution from January 2010 to June 2021. Eligibility criteria included age ≤50 years, normal-appearing ovaries on preoperative imaging, no family history of hereditary breast and ovarian cancer syndrome or Lynch syndrome, and no hormone receptor-positive malignancy. Trends in ovarian conservation were examined with the Cochran-Armitage trend test or in a logistic regression model. Associations between ovarian conservation and clinicodemographic factors before and after guideline implementation were compared using Wilcoxon rank-sum and Fisher’s exact tests.
Results Of 420 women ≤50 years of age undergoing surgery for endometrioid endometrial cancer, 355 (85%) met the criteria for ovarian conservation—267 (75%) before and 88 (25%) after guideline implementation. Median patient age was 45 years (range 25–50); 62% were non-Hispanic White, 10% Hispanic White, 8% non-Hispanic Black, 0% Hispanic Black, and 20% Asian. Patients were significantly more likely to choose ovarian conservation after (48%) compared with before guideline implementation (21%) (p<0.001). Pre-guidelines, non-Hispanic White women were less likely to elect for ovarian conservation (12%) compared with non-Hispanic Black, Asian, or Hispanic White women (28%) (p=0.002). Similarly, older women were less likely to elect for ovarian conservation compared with younger women (p<0.001). There were no differences by obesity (p=0.68), marital status (p=0.86), or insurance (p=0.89). Post-guidelines, there were no differences in ovarian conservation between non-Hispanic White women (36%) and non-Hispanic Black, Asian, or Hispanic White women (50%) (p=0.56). Older women were still less likely to elect for ovarian conservationcompared with younger women (p<0.001).
Conclusions After guideline implementation, ovarian conservation increased and uptake disparities across demographic groups decreased.
