INTRODUCTION Preoperative Gleason score is crucial, in combination with other preoperative parameters, in selecting the appropriate treatment for patients with clinically localized prostate cancer. The aim of the present study is to determine the clinical and pathological variables that can predict differences in Gleason score between biopsy and radical prostatectomy. METHODS We retrospective...
Gleason grading of prostatic specimens remains as one of the most powerful factors predicting prognosis in patients with prostate cancer. This grading system was created by Donald Gleason about 49 years ago and it takes into account the 2 most prevalent grades in the tumor sample, but it does not consider the presence of a third high grade pattern when it represents less than 5% of the whole ra...
Introduction & Objective: Prostatic carcinoma is the most common malignancy throughout the world among the males over middle age and the second leading cause of cancer-related deaths in western countries. The currently most established prognostic factors in prostatic carcinoma are histological grade (Gleason system) and tumor stage .Various new prognostic factors that have been suggested to pro...
In November, 2014, 65 prostate cancer pathology experts, along with 17 clinicians including urologists, radiation oncologists, and medical oncologists from 19 different countries gathered in a consensus conference to update the grading of prostate cancer, last revised in 2005. The major conclusions were: (1) Cribriform glands should be assigned a Gleason pattern 4, regardless of morphology; (2)...
We aimed to compare Gleason score and tumor laterality between transrectal ultrasound-guided biopsy of the prostate (TRUSBX) and radical prostatectomy (RP). Some factors that could cause a discrepancy in results between these two procedures were also evaluated. Among the 318 cases reviewed, 191 cases were selected for inclusion in this comparative study. We divided the patients into two groups ...
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 in our center, which is one ...
Introduction: Prostatic adenocarcinoma is the most common malignancy of internal system and after lung cancer is the second cause of death in male. Genetic base of many neoplasms is related to suppressor tumor gene such as P53. Therefore, we aimed in this study, to assess the intensity of prostatic adenocarcinoma tissue staining with P53 staining method and its relationship with Gleason grade. ...
A 64-year-old man with a prostate-specific antigen (PSA) of 5·74 ng/mL, no lower urinary symptoms, and family history prostate cancer presented at our clinic University College London Hospital (London, UK) in April, 2018. Axial T2-weighted MRI the showed multicystic lesion (PSA density 0·07 ng/mL/mL), MRI-targeted biopsies Gleason 3 + adenocarcinoma (Gleason Grade Group 1) prostatic intraepithe...
Gleason grading is the best independent predictor for prostate cancer (PCa) progression. Recently, a new PCa grading system has been introduced by the International Society of Urological Pathology (ISUP) and is recommended by the World Health Organization (WHO). Following studies observed more accurate and simplified grade stratification of the new system. Aim of this study was to compare the p...
