Abstract

Abstract: Objectives: This study aims to investigate whether a cribriform pattern on prostate biopsy may be a factor in suspicion of intraductal carcinoma of the prostate after radical prostatectomy. Methods: This retrospective study assessed 100 men who underwent prostatectomy from 2015 to 2019. Participants were grouped as 76 patients with Gleason pattern 4 and 24 patients without this pattern. All 100 participants underwent retrograde radical prostatectomy and limited lymph node dissection. The same pathologist evaluated all specimens. The cribriform pattern was evaluated with haematoxylin and eosin counterstaining, and intraductal carcinoma of the prostate was evaluated with immunohistochemical analysis of cytokeratin 34βE12. Results: Patients with intraductal carcinoma of the prostate on immunohistochemical analysis showed a significant tendency to relapse in the postoperative period, and those with the cribriform pattern on biopsy had a significant recurrence rate. In univariate and multivariate analyses, intraductal carcinoma of the prostate confirmed in biopsy tissue was an independent predictor of biochemical recurrence after prostatectomy. The rate of intraductal carcinoma of the prostate confirmation was 28% of cases with a cribriform pattern in biopsy tissue, which was increased to 62% in prostatectomy tissues. Conclusion: The cribriform pattern in the biopsy tissue may be a predictor for intraductal carcinoma of the prostate.
