Real-time Fluorescent ICG and 99m-Tc Nanocolloid Tracer Navigation in Bilateral Sentinel Lymph Node Mapping of Vulvar Cancer.

Study Objective: The effectiveness of sentinel lymph node (SLN) biopsy has been validated by 2 prospective trials, GROINS VI and GOG 173 [1,2]. According to the European Society of Gynaecological Oncology guideline in patients with unifocal tumors with a diameter of <4 cm, in the absence of suspected inguinal lymph nodes, SLN biopsy is recommended. The use of a radioactive tracer is mandatory [2].
