ABSTRACT
Prostate intraepithelial neoplasia (PIN) is a putative premalignant change in the human prostate, which is an intraluminal proliferation of the secretory cells of the prostatic duct-acinar system that is enveloped by a basal cell layer and displays a spectrum of dysplastic cytologic features ranging from minimal atypia (low grade PIN) to those which are ultimately indistinguishable from carcinoma cells (high grade PIN). To evaluate the clinical significance of the PIN in prostatic tumor and BPH, we reviewed the serum prostate specific antigen (PSA), prostate specific antigen density (PSAD), and pathologic findings in the specimen of 21 BPH and 11 Prostate cancers, which were pathologically confirmed. The distributions of PIN are 7/21 (33%) in BPH and 8/ 11 (73%) in prostatic ca (P0.05). There was no significant difference in the distribution of PIN according to histologic types of BPH. And high grade PIN was observed only in prostatic cancer. Therefore, if high grade PIN is observed in pathologic specimens, undetected prostatic cancer should be found.
