We will examine whether major medical conditions (e.g. diabetes, hypertension, cardiovascular diseases, etc.) influence outcomes of endometrial cancer survivors and whether they account for the observed racial/ethnic disparity in endometrial cancer survival. We will leverage data from the Multiethnic Cohort Study (MEC), a prospective study with >118,000 African-American, Japanese-American, Native Hawaiian, Latino, and Caucasian women. The MEC has large number of endometrial cancer incident cases, extensive risk factor data, long follow-up, and is directly linked with the SEER cancer registry, the Medicare, and state and national mortality databases.
