['To evaluate the causes of death among women with endometrial cancer.', 'SEER registries from 1973-1988 were queried to perform a retrospective cohort study of women with invasive epithelial endometrial cancer. Causes of death were compared according to grade and stage.', '33,232 women with incident cases of endometrial cancer had died at the time of last follow up. Overall, women were most likely to die from cardiovascular disease (35.9%, 95% CI 35.3-36.3%), followed by other causes, other malignancies, and endometrial cancer. Women with low grade localized cancer were most likely to die of cardiovascular disease, while women with high grade advanced cancer were least likely to die of cardiovascular disease and most likely to die of endometrial cancer. For the entire population, risk of death from cardiovascular causes surpasses the risk of death from endometrial cancer 5 years after diagnosis.'] Is cardiovascular disease the leading cause of death among endometrial cancer patients?
