Abstract
Background: Metabolic syndrome has been previously associated with increased endometrial cancer risk, but the relationship with metabolic syndrome and endometrial cancer survival remains unclear. Objectives: To determine the associations between metabolic syndrome using the harmonized criteria with disease-free survival, overall survival, endometrial cancer-specific survival and time to recurrence among endometrial cancer survivors. Second, to determine the association between the number of metabolic syndrome components as well as each individual metabolic syndrome component with these prognostic outcomes. Methods: A prospective cohort of 540 endometrial cancer survivors diagnosed between 2002 and 2006 participated in the Alberta Endometrial Cancer Cohort and were followed until death or March 20, 2019. Baseline in-person interviews, direct anthropometric measurements and fasting blood samples were used to assess metabolic syndrome. Recurrence and survival data were obtained via medical chart abstraction and vital status updates. Results: Compared to endometrial cancer survivors without metabolic syndrome, survivors with metabolic syndrome had worse overall survival when assessed with the harmonized criteria. Of the individual metabolic syndrome components, only waist circumference was associated with recurrence and survival outcomes. Lifetime recreational physical activity prior to diagnosis was observed to modify the associations between metabolic syndrome and its components with overall survival and disease-free survival. Conclusion: The metabolic syndrome, especially waist circumference, was associated with worse overall and disease-free survival among endometrial cancer survivors. Future research should aim to confirm these results and improve our understanding of the role lifestyle factors such as physical activity have in the association between metabolic syndrome and endometrial cancer survivors’ prognosis.
