EP626 Lymph vascular space invasion, an independent risk factor of sentinel node mapping failure in endometrial cancer, the sentifail study: a multicentric prospective analysis

Introduction/Background Sentinel lymph node (SLN) mapping has become the gold standard for surgical staging of early stage endometrial cancer. Side-specific systematic lymphadenectomy is suggested if SLN mapping failed. The objective of this study is to identify clinical and pathological factors associated with failed mapping. Methodology We prospectively evaluated a consecutive series of early stage endometrial cancer patients submitted to SLN mapping with indocyanine green (ICG) near-infrared compatible surgical platforms in two oncological referral centers from January 2018 to January 2019. Indocyanine green was injected intracervical. Bilateral mapping and failed bilateral SLN mapping g…
