AR cytoplasmic staining was directly (positively) correlated with perineural invasion (Pn) (rs = 0.142; p = 0.005), prostatectomy Gleason sum (GS) (rs = 0.146; p = 0.004), relapse occurrence (RFS) (rs = 0.122; p = 0.014), pathological tumor stage (pT) (rs = 0.160; p = 0.001), CK20 staining (rs = 0.154; p = 0.002), AR nuclear staining (rs = 0.652; p < 0.001), and AR-V7 cytoplasmic staining (rs = 0.482; p < 0.001), but it was not inversely or negatively correlated with any clinicopathological or molecular factor (Table S2). The gene discussed is KRT20; the disease is neoplasm.
