PROBLEM: Question: Does the presence of high-grade prostatic intraepithelial neoplasia or atypia on prostate biopsy adversely affect prostatectomy outcomes for patients otherwise eligible for active surveillance?
Answer: The presence of HGPIN or ASAP does not increase the risk of upgrading, upstaging, or adverse pathology at the time of prostatectomy for patients who meet the AS criteria. If otherwise suitable, HGPIN and ASAP should not impact the decision to choose AS. However, analysis of prospective AS trials is required to determine if HGPIN or ASAP impacts tumor progression once on AS.

SOLUTION: no
