NPM1 and posterior cortical atrophy: In this survey, we did not see any association of NPM1 forms with standard clinico-pathological parameters including the pathological grade (as assessed by Gleason score defining prognosis from histopathological values) supporting the idea that NPM1 phosphorylation and overexpression may play a role in castration-resistant phenotype of PCa but not in the progression from low to high grades.
