The Gleason grading system is the most powerful prognostic indicator of prostatic carcinoma and has undergone significant changes since its adoption for grading of prostate cancer. The Gleason grading system originated from a well-controlled, prospective, randomized study from 1959 to 1964 by Veteran's Affairs Cooperative Research Group.

Predictive efficacy of the 2014 International Society of Urological Pathology Gleason grading system in initially diagnosed metastatic prostate cancer. The Gleason grading system is used to help evaluate the prognosis of men with prostate cancer using samples from a prostate biopsy. Together with other parameters, it is incorporated into a strategy of prostate cancer staging which predicts prognosis and helps guide therapy.

The Gleason grading system of prostatic carcinoma is the quintessential prognostic factor in predicting findings in radical prostatectomy, biochemical failure, local recurrences, lymph node or distant metastasis in patients receiving no treatment, radiation therapy, radical prostatectomy and other therapies, including cryotherapy and high intensity focal ultrasound therapy. The Gleason grading system is intended to be applied primarily at low power Don’t go down on high power looking for one or two fused glands Should be visible at 100x (10x objective) Gleason grading for prostate primaries is based on a 5-component system (5 histologic patterns). Prostatic cancer generally shows two main histologic patterns. Changes to the Gleason Grading System 1. Poorly formed glands as Gleason pattern 4 2. Restricted criteria for cribriform pattern 4 vs.
