Prevalence of High-Grade Prostatic Intraepithelial Neoplasia in Prostate Gland of Korean Men: Comparisons Between Radical Prostatectomy and Cystoprostatectomy

The prevalence of HGPIN in Korean men with clinical prostate cancer was as great as that of Western men. Previous studies, and our results, had demonstrated a lower prevalence of HGPIN in Asian men who underwent cystoprostatectomy. The different prevalence of HGPIN found in incidental prostate cancer, between Asian and Western men, suggests that factors could be preventing the progression of prostate cancer or different characteristics of the prostate cancer in Asian populations.
