Recently, Moore et al. [85] evaluated the PSMA expression on 91 thyroid cancer specimens, including normal tissue, benign nodules, primary malignant tumours, lymph nodes, and distant metastases, demonstrating that classic PTC, follicular thyroid carcinoma, and RAI-refractory carcinomas presented the highest percentage of PSMA staining positivity among the histological subtypes. This evidence concerns the gene FOLH1 and thyroid cancer.
