 Complete pelvic and para-aortic lymphadenectomy performed at the time of primary surgical staging for endometrial cancer increases operative time and surgical morbidity, but appears to be necessary in most high grade and deeply invasive cancers. To date, the Mayo Clinic approach has not been reproduced, and the investigators propose to validate their algorithm at the University of Kentucky utilizing intra-operative consultation IOC. The preliminary data at the University of Kentucky for IOC and endometrial cancer outcomes suggest that the investigators are well-suited to perform this investigation. A surgical approach that is tailored to the patients cancer biology is rational, supported by the recent literature, and medically compelling since the co-morbidities of many obese, low-risk EC patients put them at significantly increased perioperative risk for complete lymphadenectomy.
