THE 2005 AND 2014 MODIFIED GLEASON GRADING SYSTEMS One of the biggest changes to the Gleason grading system was the classification of Grades 1 and 2. Grade 1 tumors are generally benign, and Grade 2 tumors do not appear to differ from those classified as Grade 3. In 2005, Grade 2 was recommended to be used “rarely, if ever,” and in the 2014 modified Gleason grading system, grading started from ...
BACKGROUND The Gleason score has been shown to offer important information with regard to prognosis and therapy for patients with adenocarcinoma of the prostate gland. In this study, Gleason scores, as determined by 18-gauge core needle biopsies, were compared with both Gleason scores and the pathological staging of corresponding radical prostatectomy specimens. METHODS Records of 78 consecut...
BACKGROUNDS Urologists use biopsy Gleason scores for patient counseling, prognosis prediction, and decision making. The accuracy of Gleason grading is very important. However, the variability of Gleason grading between general pathologists cannot be overlooked. Here we evaluate the discrepancy in the Gleason grading between 2 urologic pathologists and general pathologists as well as improvement...
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...
OBJECTIVES To study long-term trends in Gleason grading in a nationwide population and to assess the impact of the International Society of Urological Pathology (ISUP) revision in 2005 of the Gleason system on grading practices, as in recent years there has been a shift upwards in Gleason grading of prostate cancer. PATIENTS AND METHODS All newly diagnosed prostate cancers in Sweden are repor...
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 ...
Gleason grading is now the most widely used grading system for prostatic carcinoma in the United States. However, there are only a few studies of the interobserver reproducibility of this system, and no extensive study of interobserver reproducibility among a large number of experienced urologic pathologists exists. Forty-six needle biopsies containing prostatic carcinoma were assigned Gleason ...
