High-frequency Ultrasound for Intraoperative Lymph Node Assessment in Gynecological Cancer: From Surgery to Radiomics

Lymph node assessment is crucial in gynecological cancers (ovarian, endometrial, cervical, and vulvar), as nodal involvement significantly impacts prognosis and treatment. Despite high morbidity, systematic lymphadenectomy has been widely used for staging and treatment planning. However, in most cases, lymph nodes are free from metastasis, making the procedure unnecessary and exposing patients to severe complications such as lymphedema and infections. Sentinel lymph node (SLN) evaluation has emerged as a less invasive alternative, reducing unnecessary lymphadenectomies. However, SLN techniques face challenges, including detection failures, inaccurate frozen section analysis, and imaging limitations like false negatives in FDG PET/CT scans. The need for improved intraoperative imaging techniques is emphasized to enhance lymph node assessment, minimize surgical risks, and better tailor treatment approaches.
