The contemporary presentation and diagnosis of endometrial cancer recurrence: When, where, and how?

To examine patients with confirmed endometrial cancer recurrence; evaluate patterns, presentation, and mode of diagnosis.

A retrospective review of women with endometrial cancer diagnosis between 2014 and 2020. Disease recurrences were evaluated. Medical records were reviewed focusing on presentation at time of recurrence. Relationships were assessed using χ2, Fisher's exact test, t-test, and Wilcoxon test. The Kaplan-Meier product limit was used to estimate survival. Multiple logistic regression analysis was used to assess the impact of covariates.

Endometrial cancer recurrence was identified in 201 (11.7%) patients. Sixty percent (120/201) of patients presented with symptoms. Pain was the most common presenting symptom (23.4%, 47/201) and bleeding was reported in <14% (28/201). Patients with symptomatic presentation were less likely to be able to receive treatment for their recurrent disease (76.7% vs 91.3%, p = 0.005). Asymptomatic pelvic exam diagnosed recurrence in 13.4% (27/201) and was more common in patients initially diagnosed with early-stage disease (66.7% vs 34.5% p = 0.001) of endometrioid histology (66.7% vs 36.8%, p = 0.003) without prior adjuvant therapy (48.2% vs 17.9%, p = 0.001). More than1/3 of diagnoses were made by providers outside of the oncologic care team.

The majority of women with recurrent endometrial cancer were symptomatic and pain is a common complaint associated with disease recurrence. Patients with symptomatic presentation of disease recurrence were less likely to receive treatment for recurrent disease but this did not result in an overall survival (OS) difference. Given the rising mortality rate of endometrial cancer further work is needed to develop multidisciplinary surveillance strategies that will enable meaningful treatment of disease recurrence.
