Gleason score - (pronounced) (GLEE sun. . . ) A way of describing prostate cancer based on how abnormal the cancer cells look in a biopsy sample under a microscope and how fast they are likely to grow and spread spread. Most prostate cancers contain cells of varying degrees. The Gleason score is calculated by adding the two classes of cancer cells that make up the largest areas of the biopsied tissue sample. The Gleason score is usually between 6 and 10. The lower the Gleason score, the more the cancer cells look like normal cells and are likely to grow and spread more slowly. The Gleason score is used to plan treatment and determine prognosis (outcome)
