FOLH1 and metastatic malignant neoplasm in the lymph nodes: Specifically, sentinel node biopsy (SNB) can improve nodal staging by mapping lymphatic drainage, while prostate-specific membrane antigen radioguided surgery (PSMA-RGS) can enhance lymph node metastases (LNMs) identification through radiolabeled tracers during robot-assisted radical prostatectomy (RARP) and in the context of salvage lymph node dissection (sLND) for biochemical recurrence (BCR) after primary treatment.
