Image-guided surgical navigation for inguinal sentinel lymph node procedures in vulvar cancer

Résumé fourni par la source

OBJECTIVE: In many countries inguinal sentinel lymph node removal is conventional for staging unifocal, macroscopic vulvar cancer <4 cm, but localization can be difficult and inguinal-femoral lymphadenectomy is associated with morbidity. This study investigates the safety and feasibility of image-guided surgical navigation for localizing inguinal sentinel lymph nodes intra-operatively. METHODS: A single-center randomization feasibility study was performed (July 2022-January 2025). Twenty patients scheduled for bilateral inguinal sentinel lymph node procedure for vulvar cancer were included and randomized for intervention order (conventional/navigation first) and allocated groin for navigation (left/right). Time to localize the sentinel lymph node was recorded. Sentinel lymph node localization failure was evaluated, and complications were recorded. Surgeon's feedback on the navigation workflow was evaluated using the System Usability Scale (score 0-100), >68 being useful. RESULTS: ), non-visible methylene blue or high background radioactivity. CONCLUSIONS: This study showed that navigated sentinel lymph node procedure is feasible, and surgeons favor its use in challenging sentinel lymph node procedures.
