OBJECTIVES Lynch syndrome (LS) is a hereditary condition that increases the risk for endometrial and other cancers. Recognizing women at risk for LS based on personal/family history is burdensome and imprecise. Tumor testing using microsatellite instability (MSI) testing and immunohistochemistry (IHC) for mismatch repair protein expression can be an effective strategy for identifying potential ...

65-year-old woman presented with a 2-month history of postmenopausal bleeding. Her past medical history was significant for hypertension, type 2 diabetes, and a remote history of pulmonary embolism, and her surgical history was significant for a thyroidectomy for benign disease and a hip replacement. On physical examination, she was found to have a mass protruding through the cervix. Biopsy rev...

Endometrial cancer is the most commonly diagnosed gynecologic malignancy in the United States. A well recognized disparity by race in both incidence and survival outcome exists for this cancer. Specifically Caucasians are about two times more likely to develop endometrial cancer than are African-Americans. However, African-American women are more likely to die from this disease than are Caucasi...

Endometrial cancer is the most common gynecologic malignancy in the United States and the most frequent extracolonic tumor in hereditary nonpolyposis colorectal cancer (HNPCC). HNPCC patients have inherited defects in DNA mismatch repair and the microsatellite instability (MSI) tumor phenotype. Sporadic endometrial cancers also exhibit MSI, usually associated with methylation of the MLH1 promot...

OBJECTIVE Both adenomyosis and endometriosis are characterized by the presence of ectopic endometrial glands and stroma and have been suggested to share some characteristics with malignant tumors. Although accumulating evidence indicates that endometriosis is associated with some cancer types, the cancer risks in patients with adenomyosis have been rarely examined. In this study, we investigate...

BACKGROUND In contrast with the decreasing incidence seen for most cancers, endometrial cancer has been increasing in the United States. We examined whether the increasing incidence and mortality from endometrial cancer are equally distributed by race/ethnicity and tumor histologic subtype. METHODS Surveillance, Epidemiology, and End Results (SEER) endometrial cancer incidence and mortality d...

BACKGROUND Sugar-sweetened beverage (SSB) intake has been associated with an increased risk of obesity and type II diabetes. However, its association with endometrial cancer is unclear. METHODS We evaluated dietary intake of SSB, fruit juice, sugar-free beverages, sweets/baked goods, starch, and sugars among 23,039 postmenopausal women in the Iowa Women's Health Study. Incident estrogen-depen...

The involvement of hormonal factors in developing endometrial cancer is well documented. In particular, excess or unopposed estrogen is a major risk factor. Endometrial cancer is divided into estrogen-dependent and estrogen-independent types. Studies suggested that the subtypes of endometrial cancer share many common risk factors. Whether the levels of sex hormones differ between types 1 and 2 ...

Fat accumulation in adipose tissues is a risk factor for the development of human cancers. However, there are no studies describing the fat accumulation in adipose tissue or its distribution in human endometrial cancer. We first examined fat accumulation in adipose tissues separately on CT images of 122 patients with endometrial cancer, and investigated the correlation of these findings with va...
