Intraoperative Examination of Sentinel Node in Endometrial Cancer (TRSGO-SLN-003)

More than half of the cases with macrometastatic sentinel lymph node (SLN) have non-SLN metastasis and leaving these nodes in-situ may impair the survival. This study assessed the diagnostic accuracy of intraoperative SLN frozen section examination and scrape cytology as a possible solution for management of SLN positive patients. Clinical early stage endometrial cancer patients who underwent SLN algorithm and intraoperative frozen section or scrape cytology to evaluate SLN status for metastasis were analyzed retrospectively. Intraoperative examination findings were compared with final pathology results and diagnostic accuracy of frozen section and scrape cytology were evaluated.
