MCC-24-GYN-11: Comparison of Nodal Sampling in Endometrial Cancer

Intraoperative Consultation, performed by pathologist and surgeon jointly. The uterus is inspected for extra-corpus spread (cervix, parametria, adnexa, distant). The surgical pathologist will evaluate the uterus according to the IOC Worksheet and promptly notify the surgeon of the results. The IOC will include evaluation for extra-corpus disease, lesion measurement, frozen section (to confirm measured lesion is malignant, cell type, and re-grading of tumor). Non-sentinel nodes will be handled according to institutional standard-of-care practice.

The surgeon will perform a side-specific lymphadenectomy when there is no mapping on a hemipelvis (no tracer uptake in nodes). If neither side has successful Sentinel Node mapping, the surgeon performs a complete pelvic lymphadenectomy. Surgeons will remove the para-aortic lymph nodes at their discretion.
