    Biomarkers for Endometrial and Ovarian Cancer

    Active recruiting

    PURPOSE: This is a biological sample collection study aimed at developing an early diagnostic tool for endometrial and ovarian cancer. The investigators are studying the relationship between estrogen driven gynecological cancers, inflammation and the microbiome. Patients who have been diagnosed with endometrial cancer or undergo presurgical evaluation for suspicion of ovarian cancer who are scheduled for a hysterectomy, bilateral oophorectomy and/or salpingectomy are eligible. Control patients undergoing gynecological surgery for benign indications are also being recruited.

    Endometriosis and the Microbiome

    Active recruiting

    PURPOSE: Endometriosis is an inflammatory disorder in which the tissue that lines the inside of the uterus (the endometrium) spreads to the pelvic and peritoneal cavities outside of the uterus. This is a biological sample collection study examining how bacteria located within the vagina, the urogenital tract and the gastrointestinal tract may affect the development of endometriosis. Investigators are also exploring how an individual’s microbiome affects their estrogen metabolism and inflammation.
