Abstract: Objective: In this study, we investigated the concordance between Gleason scores of transrectal ultrasound guided biopsy and radical prostatectomy specimens in patients diagnosed with prostate cancer via transrectal ultrasound guided biopsy and treated with radical prostatectomy in our clinic.

Material and Method: 115 patients were included in our study treated with radical prostatectomy for organ-confined prostate cancer between the dates of November 2011 and December 2014. Data of these patients are reviewed retrospectively.

Results: The average age of the patients was 61.8 ± 6.8 (43-76) years. The average body mass index of these patients were (BMI) 26.7 ± 3.34 (19.3 – 35.3) kg/m². Average PSA value was 6.6 ± 10.1 (1.4 – 80) ng/ml. Gleason scores of transrectal ultrasound guided biopsy and radical prostatectomy were observed concordant in 74 (64.3%) of 115 patients, while 41 (35.6%) were not concordant. Gleason score was decreased by 1 grade for 8.6% (10 patients) of patients, it was increased by 1 for 26.0% (30 patients) of patients and for 0.8% (1 patient) it was increased by 3.

Discussion: These findings indicate indicate that Gleason scores of transrectal ultrasound guided biopsy and prostatectomy specimens may be discordant.

Keywords: Gleason score, prostate biopsy, prostate cancer, PSA, radical prostatectomy.
