A NEW CONTEMPORARY PROSTATE CANCER GRADING SYSTEM Problems with the Current Gleason System: 1) Scores 2-5 are currently no longer assigned and certain patterns that Gleason defined as a score of 6 are now graded as 7, thus leading to contemporary Gleason score 6 cancers having a better prognosis than historic score 6 cancers.

Gleason score is the sum of the two most prevalent Gleason grades: primary and secondary, designated according to separate rules for biopsy and prostatectomy ; If only one pattern is present, the primary and secondary patterns are given the same grade (ex: 3+3=6)

It’s also important to know whether any cells rated at Gleason grade 5 are present, even in just a small amount, and most pathologists will report this.
