Prostate Cancer - 6

The Gleason Score was named for the pathologist who developed the grading system to determine risk. Beginning in 2018, some expect the categories based on the Gleason Score to be as follows:

Grade	Major	Minor	Total
One	3/5	3/5	6/10
Two	3/5	4/5	7/10
Three	4/5	3/5	7/10
Four	45	4/5	8/10
Five	5/5	4/5	9/10 or greater

·         Low risk disease: Gleason 6/10, few cores positive, and PSA less than 10.

·         Intermediate risk: Gleason 7/10 and/or PSA 10-20.

·         High risk disease: Gleason 8/10 or above and/or PSA greater than 20.
