Abstract

PURPOSE: Obesity is associated with endometrial cancer (EC) development and cardiovascular disease (CVD) mortality. As the number of obese EC survivors continues to increase, an examination of CVD mortality in this vulnerable population is warranted.

METHODS: In the Iowa Women's Health Study (1986-2011), we examined CVD mortality among 552 women with EC compared with 2,352 age- and body mass index-matched women without EC (controls). Hazard ratios (HRs) and 95% confidence intervals (CIs) for CVD mortality were estimated using multivariable-adjusted Cox proportional hazards regression models stratified by an indicator for match set.

RESULTS: Compared to controls, women with EC more often reported a history of diabetes, hypertension, and never smoking. Compared with controls, women with EC had lower CVD mortality (HR 0.75, 95% CI 0.56-0.99), and higher all-cause mortality (HR 1.50, 95% CI 1.30-1.74).

CONCLUSIONS: Although some CVD risk factors were more common in women with versus without EC, CVD mortality was lower among the former group. Additional well-adjusted analyses with larger study populations are needed to understand interactions between CVD risk factors with CVD mortality among EC survivors. The CVD risk factor profile of EC survivors warrants emphasis on cardiovascular health.
