FOLH1 and neoplasm: A study from Ross et al. indicated that patients with tumors that show high PSMA expression in immunohistochemistry had a significantly increased rate of tumor grade (p = 0.03), pathological stage (p = 0.029), aneuploidy (p = 0.01) and biochemical recurrence (p = 0.001) as compared to tumors featuring a relatively lower PSMA expression [13].
