Tissue Expression of Androgen Receptor Splice Variant 7 at Radical Prostatectomy Predicts Risk of Progression in Untreated Nonmetastatic Prostate Cancer.

Androgen receptor splice variant V7 (AR-V7) was recently detected in circulating tumor cells of castration-resistant prostate cancer (PC) patients and its expression correlated with resistance to new-generation androgen signaling inhibitors.
