AR and posterior cortical atrophy: A systematic revision by Wolf et al. demonstrated that a PSA cutoff of 4.0 ng/mL yielded a sensitivity of 21% with a specificity of 91% for the detection of overall PCa, differently from our study, in which the AR-V7 cutoff point of 4.930e-005 had a sensitivity and specificity of 73.91% and 81.82%, respectively (Wolf et al. 2010).
