Abstract:
Objective:To explore the quality differences of systemic biopsy specimens from different regions in prostate biopsy.Methods:The data of 806 patients who underwent transperineal prostate biopsy from May 2013 to December 2020 in Northern Jiangsu People’s Hospital were retrospectively reviewed. The median age of the patients was 72 (66, 77) years old, median PSA was 18.4 (10.3, 34.2) ng/ml, and prostate volume was 43 (32, 56) ml. Tissue quality were graded from low to high as follows. One score means multiple fragments with fragmented tissue ≤5 mm. Two scores means at least one fragment >5 mm and ≤10 mm. Three scores means at least one fragment >10 mm. The prostate specimens fragmentation scores and the length of the specimens in different regions of the prostate were collected to analyze.Results:A total of 806 patients were included in our study. The number of tissues was 8 866, and the mean length of tissues was 1.2 (1.0, 1.5) cm. The tissues of different region were scored according to the scoring criteria, of which 618 (7.0%) prostate tissues were scored as 1 score, 2 720 (30.7%) tissues were scored as 2 scores, and 5 528 (62.4%) tissues were scored as 3 scores. In the prostate apex, tissue quality of 1 score accounted for 11.7%(94/806), 2 scores accounted for 34.7%(280/806), and 3 scores accounted for 53.6%(432/806). While in the prostate base, tissue quality of 1 score accounted for 6.5%(524/8 060), 2 scores accounted for 30.3%(2 449/8 060), and 3 scores accounted for 63.2%(5 096/8 060)( H=35.850, P<0.05). The mean length of the prostate apical tissue was 1.0 (0.8, 1.3) cm, which was significantly shorter than prostate basal tissue of 1.2(1.0, 1.5) cm ( Z=-11.353, P<0.05). Conclusions:In transperineal prostate biopsy, the apical tissue was more fragmented and shorter, prostate apex should be concerned.
