OBJECTIVE: DACH1 is a transcriptional repressor and tumor suppressor gene frequently mutated in melanoma, bladder, and prostate cancer. Loss of DACH1 expression is associated with poor prognostic features and reduced overall survival in uterine cancer. In this study, we utilized the Oncology Research Information Exchange Network (ORIEN) Avatar database to determine the frequency of DACH1 mutations in patients with endometrial cancer in our Kentucky population.

METHODS: We obtained clinical and genomic data for 65 patients with endometrial cancer from the Markey Cancer Center (MCC). We examined the clinical attributes of the cancers by DACH1 status by comparing whole-exome sequencing (WES), …

Metformin As A Therapeutic Target In Endometrial Cancers., Teresa Lee, Ubaldo E. Martinez-Outshoorn, Russell J. Schilder, Christine H. Kim, Scott D. Richard, Norman G. Rosenblum, Jennifer Johnson

Endometrial cancer is the most common gynecologic malignancy in developed countries. Its increasing incidence is thought to be related in part to the rise of metabolic syndrome, which has been shown to be a risk factor for the development of hyperestrogenic and hyperinsulinemic states. This has consequently lead to an increase in other hormone-responsive cancers as well e.g., breast and ovarian cancer. The correlation between obesity, hyperglycemia, and endometrial cancer has highlighted the important role of metabolism in cancer establishment and persistence. Tumor-mediated reprogramming of the microenvironment and macroenvironment can range from induction of cytokines and growth factors to stimulation …

Prevention Of Ovarian And Endometrial Cancer By Combined Oral Contraceptives: A Demographics Study, Joanna S. Heywood

CMC Senior Theses

Endometrial cancer is the most common gynecologic cancer with 54,870 cases occurring in the United States in 2015 and causing 10,170 deaths, an 18.5% mortality rate (Elit and Reade, 2015). Ovarian cancer, while less common, is much more fatal. In 2015 in the United States, 21,290 cases occurred and resulted in 14,180 deaths, a 66.6% mortality rate. This mortality rate makes ovarian cancer the fifth most deadly cancer for women in the United States, which is largely explained by ineffective screening strategies and limited treatment possibilities (Cramer, 2012). Thus, developing effective prevention strategies is especially important to saving the lives …

Mismatch Repair Deficient Tumors Lacking Known Sporadic Causes: Are They All Due To Lynch Syndrome?, Katherine M. Dempsey

Dissertations & Theses (Open Access)

BACKGROUND: Mismatch repair deficient (MMRD) colorectal (CRC) or endometrial (EC) cancers in the absence of MLH1 promoter hypermethylation and BRAF mutations are suggestive of Lynch syndrome (LS). Positive germline genetic test results confirm LS. It is unclear if individuals with MMRD tumors but no identified germline mutation or sporadic cause (MMRD+/germline-) have LS.

HYPOTHESIS: Since LS is hereditary, individuals with LS should have a stronger family history of LS-related cancers than individuals with sporadic tumors. We hypothesized that MMRD+/germline- CRC and/or EC patients would have less suggestive family histories than LS CRC and/or EC patients.

METHODS: 253 individuals with an …
