FOLH1 and metastatic malignant neoplasm in the lymph nodes: Ciccarese et al., using PI-RR score, obtained a higher detection rate compared with both choline-PET/CT and PSMA-PET/CT for local recurrence, [7] while Radzina et al. identified a superiority of PSMA-PET/CT only for the detection of distant and lymph node metastases [17]; as well, in our study eleven patients had a positive PET-CT at another location (one patient had a bone metastasis and ten patients had lymph nodal metastases).
