Analyzing only tumors with strong neovascular PSMA expression (labelling index 2), malignant tumors with a high PSMA expression were more frequent (39/599; 6.51%) compared to tumors of intermediate biological potential (3/148; 2.03%) and benign tumors (1/32; 3.13%) (p = 0.078, Fisher ́s exact test, malignant vs. intermediate/benign tumors). Here, FOLH1 is linked to cancer.
