Influence of biopsy perineural invasion on long-term biochemical disease-free survival after radical prostatectomy.

OBJECTIVES To investigate the influence of biopsy perineural invasion (PNI) on long-term prostate-specific antigen recurrence rates, final pathologic stage, and surgical margin status of men treated with radical prostatectomy. Radical prostatectomy offers the best chance for surgical cure when performed for organ-confined disease. However, the histologic… (More)
