The most differentiated tumor would have the lowest score, Gleason 2 (1+1), while the most undifferentiated neoplasm (not resembling native prostate tissue) would have the highest score, Gleason 10 (5+5). Gleason scores range from 2 to 10; by definition there is no score of 0 or 1. [4] [7]
Of the many cancer-specific schemes, the Gleason system, [3] named after Donald Floyd Gleason, used to grade the adenocarcinoma cells in prostate cancer is the most famous. This system uses a grading score ranging from 2 to 10. Lower Gleason scores describe well-differentiated less aggressive tumors.
Hip scoring is a procedure used to determine the degree of hip dysplasia in dogs and other animals and reporting the findings in a standard way. The hip score is the sum of the points awarded for each of nine radiographic features of both hip joints. The British Veterinary Association uses the following criteria to determine hip score: Norberg ...

A walk: This is very important for working breeds, but dogs like Great Pyrenees need to walk an hour at least three times a day, and many people do not have the time for that. A backpack helps a ...
These scores are then added to obtain the final Gleason score. For example, a prostate biopsy specimen may exhibit two different patterns, one which is assigned a number two and the other a number three. The final Gleason score in this case would be five." The basic measure is the grade, and the sum is the score.
However, Shola, an English Shepherd who was forced to retire as a mountain rescue dog due to the condition, has helped scientists create a new test that could mean the end of PRA.
For prostate cancer, cell morphology is graded based on the Gleason grading system. [citation needed] Of note, this system of describing tumors as "well-", "moderately-", and "poorly-" differentiated based on Gleason score of 2–4, 5–6, and 7–10, respectively, persists in SEER and other databases but is generally outdated. In recent years ...
