Of interest, of the n = 17 patients with positive tumor cell PSMA expression n = 13 patients were male (76%; p > 0.05, two-sided Fisher’s exact test) and n = 112 patients with positive neovascular PSMA expression (83%) were male (p = 0.011, two-sided Fisher’s exact test; Table 2). Here, FOLH1 is linked to neoplasm.
