From the 2005 to the 2014 These two numbers added together produce the total Gleason score, which is a number between 2 and 10. A higher score means The five Gleason grade groupings (GGGs) ranging from 1 to 5 are defined as Gleason scores 6, 3+4, 4+3, 8, and >8, respectively (2).This new grading system It is based on the Gleason score, which is another type of prostate cancer grading system.

Together with other parameters, it is incorporated into a strategy of prostate cancer staging which predicts prognosis and helps guide therapy. A Gleason score is given to prostate cancer based upon its microscopic appearance.
Sometimes, it can be hard to predict how well people will do based just on their Gleason scores alone. For example, your tumor may be assigned a Gleason score of 7 if the two most common grades were 3 and 4.The 7 may come either from adding 3 + 4 or from adding 4 + 3. The Gleason Grading System: A Complete Guide for Pathologists and Clinicians provides exhaustive coverage of the updated Gleason Grading System, which deals not only with pathology but also with the associated clinical correlations and prognosis. The Gleason Grading System is the most important prognostic marker of prostate cancer, which is critical to patient management and drives therapies
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.

Your consultant may report your score either as a Gleason Score or an ISUP Grade Group,
