Perineural invasion is a prognostic factor for biochemical failure after radical prostatectomy

Abstract

In this series, PNI was associated with established parameters of biologically aggressive disease, and was an important prognostic factor for biochemical failure-free survival in patients undergoing radical prostatectomy. This finding supports routine evaluation of the PNI status in radical prostatectomy specimens and suggests that patients with PNI should be more closely followed after surgery.
