2017-03-08 · This is called the Gleason system. Grades 1 and 2 are not often used for biopsies − most biopsy samples are grade 3 or higher. If the cancerous tissue looks much like normal prostate tissue, a grade of 1 is assigned. If the cancer cells and their growth patterns look very abnormal, a grade of 5 is assigned.

Gleason grading system

2021-04-02 The Gleason Score is the grading system used to determine the aggressiveness of prostate cancer. This grading system can be used to choose appropriate treatment options. The Gleason Score ranges from 1-5 and describes how much the cancer from a biopsy looks like healthy tissue (lower score) or abnormal tissue (higher score). The Gleason grading system is the most commonly used pathologic grading system for adenocarcinoma of the prostate. Tissue samples are examined under low magnification, and the two most common gland architectural patterns are assigned a grade from 1 to 5 and reported as a Gleason score. The Gleason score is the most common system doctors use to grade prostate cancer. The grade of a cancer tells you how much the cancer cells look like normal cells.

Gleason score is the sum of the two most prevalent Gleason grades: primary and secondary, designated according to separate rules for biopsy and prostatectomy ; If only one pattern is present, the primary and secondary patterns are given the same grade (ex: 3+3=6)
