Abstract: High-grade prostatic intraepithelial neoplasia (PIN) is the most
likely precursor of prostatic carcinoma. PIN has a high predictive value as a
marker for carcinoma, and its identification in biopsy specimens warrants
repeat biopsy for concurrent or subsequent carcinoma. The only methods of
detection are biopsy and transurethral resection; PIN does not significantly
elevate serum PSA concentration or its derivatives, does not induce a palpable
mass, and cannot be detected by ultrasound. Androgen deprivation therapy
decreases the prevalence and extent of PIN, suggesting that this form of
treatment may play a role in chemoprevention. Radiation therapy is also
associated with a decreased incidence of PIN.
