Abstract
OBJECTIVE: To identify the most common causes of death and potentially modifiable risk factors in endometrial cancer patients. METHODS: 745 women diagnosed with incident endometrial cancer were enrolled in a population-based study from 1991 to 1994. Participants completed structured interviews about 1 year after diagnosis. Study files were linked with the National Death Index to identify dates and causes of death through 2016. Proportional hazards regression was used to estimate hazard rate ratios for cause of death adjusting for age and stage of disease. Hazard ratios were also examined according to comorbidities. RESULTS: Of the 745 women, 450 were deceased after a median of 19.9 years. The two most common causes of death were cardiovascular disease (N = 145, 32%) and any cancer (N = 135, 30%), with only 10% of women dying from endometrial cancer (N = 46). Obesity, diabetes and smoking increased risk of all-cause mortality (HRR 1.77, 95%CI 1.36-2.31; HRR 1.74, 95%CI 1.34-2.27; HRR 1.59, 95%CI 1.16-2.17). Diabetes also increased risk of cardiovascular disease-specific mortality (HRR 1.98, 95%CI 1.38-3.08), but not endometrial cancer mortality (HRR 0.55, 95%CI 0.21-1.48). Neither obesity nor smoking was associated with increased risk of cardiovascular disease-specific mortality (HRR 1.46, 95%CI 0.92-2.32; HRR 1.21, 95%CI 0.67-2.18) nor endometrial-cancer specific mortality (HRR 1.81, 95%CI 0.83-3.93; HRR 0.61, 95%CI 0.17-2.15). CONCLUSIONS: Endometrial cancer patients were 3 times more likely to die of cardiovascular disease than endometrial cancer. Obesity, smoking and diabetes increase the risk of death in these patients and are potentially modifiable. Clinical trials should be developed that incorporate counseling regarding these risk factors into survivorship care to determine impact on mortality.
