Abstract

Background: The purpose of this study was to determine the degree of alignment of prostate carcinoma in a rectal biopsy with radical prostatectomy in patients with prostate carcinoma to determine which biopsy samples are consistent with surgical specimens. Methods: In this cross-sectional study, out of 122 patients with prostate cancer who had undergone radical prostatectomy surgery in Sina hospital of Tabriz 65 patients with clinical records and pathological reports of needle biopsy, and radical prostatectomy biopsy specimens were available.The required information was recorded in questionnaire made for this study, and then the pathologic report and Gleason score and lymph-vascular involvement of the specimens were determined separately and finally the Trans rectal pathology report of the biopsy was compared with the histopathology report of radical prostatectomy in each patient. Results: The most common Gleason score and radical prostatectomy score were 6 (41.5%) and 6(40%), respectively. The lowest frequency of Gleason score, radical of the prostatectomy, and Trans rectal biopsy score were 10 (3.1%), 8(4.6%)%), and 4(4.6%), respectively. Generally, 24.6% of the prostatectomy samples were similarly scored, while 63.1% reported Trans rectal biopsy specimens and 12.3% reported low Trans rectal biopsy. By grouping the samples into histopathology levels this association was 41.5% identical in terms of scores and 49.2% in excess and 9.2% in lower reporting. The most common histopathology degree was rarely (49%) in Trans rectal biopsy and moderate in 40% in radical prostatectomy about 43% of badly differentiated cancers in the surgical specimens remained at the same level and the highest reporting rates were in the group with a good degree of distinction (66%). The highest correlation between rectal biopsy samples and radical prostatectomy samples was at the 6th grade and lowest compliance rate was in 4th and 8th grades. Conclusion: The highest degree of alignment was in the bad differentiation group, which indicates the high predictive power of biopsy specimens at this degree of differentiation. The present study suggests that the size of the smaller prostate and the high pre-surgical PSA may be predictive of increasing the Gleason score after radical prostatectomy.
