Determine the Utility of Liquid Biopsies and Tumor Molecular Profiling in Predicting Recurrence in Endometrial Cancers

This study is to find out how well liquid biopsies work as a non-invasive alternative to other methods of finding cancer cells (such as a tissue biopsy) in patients with endometrial cancer. A liquid biopsy is a blood test that may be able to find cancer cells. Collecting and storing samples of blood and tissue from patients with endometrial cancer to study in the laboratory may help doctors learn how the cells in the blood may change during treatment for uterine cancer.
