The addition of PSMA-PET-CT to the available nomograms (Briganti 2012, Briganti 2017, and MSKCC) was reported to improve the accuracy of the established models for predicting LNI (18), despite the sensitivity of preoperative PSMA-PET/CT for predicting LNI was reported to be <50% (24–26), and PSMA-PET/CT tended to especially miss small lymph node metastases (<5 mm) (27). Here, FOLH1 is linked to metastatic malignant neoplasm in the lymph nodes.
