Background and Objective: Today’s, the Gleason grading system is well known as the world’s most commonly used histological system for prostate cancer. It provides significant information about the prognosis. This prospective paper assessed the correlation of transrectal ultrasound (TRUS) guided biopsy and radical prostatectomy specimens in terms of Gleason scores. In this matter, the effect of ...

results a total number of 43 specimens were studied, from which 9 were obtained from patients with metastatic prostate cancer. the expression of five examined genes had no correlation with psa level and gleason score. the expression of amacr decreased in metastatic prostate cancer (p = 0.02). the expression of other genes showed no difference between metastatic and non-metastatic tumors (p > 0....

Background: Presence of discordance between the Gleason score on needle biopsy and the score of radical prostatectomy specimen is common and universal. In this study, we determined the accuracy of Gleason grading of biopsies in predicting histological grading of radical prostatectomy specimens and the degree of overgrading and undergrading of prostatic adenocarcinoma i...

OBJECTIVES This study examined the rate of Gleason pattern 5 and the influence of tertiary Gleason pattern 5 on oncological outcomes. METHODS Four hundred sixty-six patients underwent a radical prostatectomy between 1993 and 2008. Each surgical specimen was reviewed and assessed for the tumor diameter, Gleason score (which was based on the 2005 International Society of Urological Pathology Co...

conclusions although the presence of pni in prostate biopsy is accompanied by higher surgical stages, pni is not an appropriate independent factor in risk stratification. patients and methods this cross-sectional study was conducted using a sample of 109 patients who attended a tertiary health care center from 2008 to 2013. the selection criteria were pni in prostate biopsy with gleason scores ...

OBJECTIVES To assess the metastasis-free survival (MFS) and disease-specific survival (DSS) in men with Gleason score ≤6 prostate cancer at radical prostatectomy (RP). PATIENTS AND METHODS We included 1101 consecutive RP patients operated between March 1985 to July 2013 at a single institution. The outcome variables were MFS and DSS. The postoperative survival was estimated by the Kaplan-Meie...

The grading of prostate cancer has undergone significant changes since the adoption of the Gleason grading system in the 1970s. Gleason patterns 1 and 2 are no longer in use and the current Gleason score 6 of 10 is the lowest grade possible. Several specific morphologies that were historically considered Gleason grade 3 are currently assigned a Gleason pattern 4. Consequently, current Gleason s...
