The Gleason grading system is used to help evaluate the prognosis of men with prostate cancer using samples from a prostate biopsy.Together with other parameters, it is incorporated into a strategy of prostate cancer staging which predicts prognosis and helps guide therapy.
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based on Gleason score of 2–4, 5–6, and 7–10, respectively, persists in SEER and other databases but is generally outdated.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 ...
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.
The Gleason grading system is commonly used, where the pathologist assigns numbers ranging from 3 (most similar to healthy prostate tissue) to 5 (least similar) to different regions of the biopsied tissue. They then calculate a "Gleason score" by adding the two numbers that represent the largest areas of the biopsy sample. [28]
Gleason remained at the Minneapolis VA Medical Center after World War II. In 1962, Dr. George Mellinger, the hospital's chief of urology, who was administering a cooperative research project involving fourteen hospitals, asked Gleason to develop a standardized pathological testing system to measure the development of prostate cancer. At the ...
