Ex: Gleason pattern 3=95% and pattern 4=5%, Gleason score=3+4=7. For multiparametric MRI targeted biopsies: Gleason scores should be given for the aggregate of ...
The Prostate Cancer Gleason Score score ranges from 2 to 10. To determine the Gleason score, the pathologist uses a microscope to look at the patterns of cells in the prostate tissue. The most common cell pattern is given a grade of 1 (most like normal cells) to 5 (most abnormal). If there is a second most common cell pattern, the pathologist ...
