To clarify the clinical and pathological feature of high-grade PIN and atypical glands at first prostate needle biopsies, we retrospectively studied 678 patients who received first prostate needle biopsy from 2000 to 2007. Incidences of high-grade PIN and atypical glands were 3.7%(25 patients)and 1.0%(13 patients)respectively. The prostate cancer detection rate at the rebiopsy in patients with atypical glands, high-grade PIN and no premalignant lesion was 40%, 40% and 24.7%, respectively. The chi-square test did not show a statistically significant difference among the patients with high-grade PIN or atypical glands and no premalignant lesion in terms of the prostate cancer detection rate of rebiopsy. There is no significant difference between the patients with HGPIN or AG and no premalignant lesion at the prostate cancer detection rate of rebiopsy. However the prostate cancer detection rate at the rebiopsy in patients with AG and HGPIN was relatively high. So the patients with HGPIN and AG may need rebiopsy.
