The purpose of this study is to see how people's diets, other aspects of their lifestyles, and their individual genetic makeup affect their chances of getting endometrial cancer (cancer of the uterus).

This survey will enroll several hundred women who have or have had endometrial cancer and several hundred who do not. We will compare these two groups of women to see what factors may lead to endometrial cancer.

We will conduct a population-based case-control study in six counties of New Jersey. Cases will be women with newly-diagnosed endometrial or ovarian cancer. Controls will be matched by 5-year age groups and selected by random digit dialing (for those under 65), from Centers for Medicare and Medicaid Services (CMS) files (for those 65 and over), or from neighborhood sampling. Controls will not have had a hysterectomy.

There will be 400 cases with endometrioid tumors, 60 with serous tumors or clear cell tumors, 300 with ovarian cancer, and 400 controls. In addition, there will be a small group of black women included from MSKCC.

We will interview participants about known and potential risk factors for endometrial and ovarian cancer and obtain information on diet. We will obtain DNA for genetic analysis from buccal specimens collected using a mouthwash rinse method. We will use logistic regression to determine odds ratios for disease with various exposures. For endometrial cancer, we will examine the association of risk with genotypes in strata defined by body mass index and dietary fat consumption.

Inclusion Criteria:

• Diagnosed with epithelial endometrial or ovarian cancer within the year before being contacted (cases)
• Aged 21 and over
• Residents of Essex, Union, Morris, Middlesex, Bergen, or Hudson counties, NJ
• Black women with and without endometrial cancer who are seeing gynecologists at MSKCC

Exclusion Criteria:

• Unable to sign informed consent
• Consent withheld by physician (cases)
• Hysterectomy (controls)
• Do not speak English or Spanish

In collaboration with the New Jersey Department of Health and Senior Services NJDHSS), we will use rapid case ascertainment to identify patients as they are diagnosed.For controls aged 65 and over, we will obtain lists from CMS of a sample of women in the 6 counties. As an alternative way of reaching controls, we will conduct area sampling.
