In summary, the 2005 ISUP modifications to the Gleason grading system for prostate carcinoma accurately categorize patients by pathological findings and short‐term biochemical outcomes. While retaining the essence of the Gleason system, there is a need for a change in its reporting to more closely reflect tumour behaviour.

Original Gleason grading system Donald F. Gleason in 1966 created a unique grading system for PCa based solely on the architectural pattern of the tumour, using a five-point scale, where patterns 1e3 represent tumours which most closely resemble normal prostatic glands and patterns 4 and 5 tumours show increasingly abnormal glandular architecture

A lower Gleason grade means that the cancer is slower growing and not aggressive. Conclusions: It is remarkable that nearly 40 years after its inception the Gleason grading system remains one of the most powerful prognostic factors for prostate cancer. This system has remained timely because of gradual adaptations by urological pathologists to accommodate the changing practice of medicine. The Gleason scoring system is the most common prostate cancer grading system used. The pathologist looks at how the cancer cells are arranged in the prostate and assigns a score on a scale of 3 to 5 from 2 different locations. Cancer cells that look similar to healthy cells receive a low score.

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.

2012-07-16 2019-12-23 The Gleason grading system ranges from 2 to 10, yet 6 is the lowest score currently assigned. When patients are told that they have a Gleason score 6 out of 10, it implies that their prognosis is intermediate and contributes to their fear of having a more aggressive cancer. 2006-05-11 Posts about Gleason Grading System written by Greg Lance - Watkins (Greg_L-W) Life's Roller Coaster If I'm missing, or not taking messages sorry – I'm more angry about letting my friends down than YOU will ever be at being let down!
