The definition for the new grading system is based on the modified Gleason grading system and incorporates changes made in 2005 and 2014 (see Table 1). The new system was validated in a multi-institutional study of over 20,000 radical prostatectomy specimens, over 16,000 needle biopsy specimens, and over 5,000 biopsies followed by radiation therapy (3).

The Gleason grade is a numbering system that indicates the aggression level of prostate cancer cells. The sample cells are obtained by a needle biopsy of the prostate and examined under a microscope by a pathologist who assigns a grade (number value) to each sample. A Gleason score of 7 is a medium-grade cancer, and a score of 8, 9, or 10 is a high-grade cancer. A lower-grade cancer grows more slowly and is less likely to spread than a high-grade cancer.
