ABSTRACT
OBJECTIVES: To assess the impact of the COVID-19 pandemic on endometrial cancer stage and surgical treatment in Ontario, Canada. METHODS: This descriptive study identified cases from January 1, 2017 to December 31, 2021 from endometrial cancer hysterectomy specimens in the Ontario Health-Cancer Care Ontario, ePath system. Endometrial biopsy records from January 1, 2016 to December 31, 2021 were matched to surgical specimens by provincial health card number. Time to surgery and surgical stage were compared before (2017-2019) and during (2020-2021) the COVID-19 pandemic. RESULTS: There were 10 446 women treated with hysterectomy for endometrial cancer in Ontario from 2017-2021. In April and May 2020, corresponding with the provincial state of emergency, there was a 56% relative reduction in endometrial biopsies. Despite this 2-month reduction in endometrial biopsy volume, there was no change in surgical volume for endometrial cancer treatment. The median time from endometrial biopsy to surgery was 56 days (IQR 40, 80) during the pandemic (2020-2021) compared to 58 days (IQR 43, 82) prior to the pandemic (2017-2019) (P < 0.001). There was no upstaging of endometrial cancer during the COVID-19 pandemic. CONCLUSIONS: The Ontario healthcare system continued to prioritize service delivery to endometrial cancer patients during the COVID-19 pandemic, despite the increase in virtual care and decrease in operating room time. There were no significant surgical delays or upstaging of endometrial cancer.
