Higher numbers indicate a faster growing cancer that is more likely to spread. 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. A Gleason score is given to prostate cancer based upon its microscopic appearance. Cancers with a higher Gleason score are more aggressive and have a worse prognosis. Pathological scores range from 2 to 10, with higher numbe Gleason score 7 (or 3 + 4 = 7) Grade Group 2: Most cells still look similar to normal prostate cells.

Gleason grade 4 is probably the most important grade because it is fairly common and because of the fact that if a lot of it is present, patient prognosis is usually (but not always) worsened by a considerable degree.

Gleason grade

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). In 1966, Dr. Donald Gleason (Cancer Chemother Rep 1966;50:125) devised grades of 1 - 5, based on glandular architecture and microscopic appearance using a 4X - 10X objective eyepiece, that were shown to predict outcome in prostate cancer A Gleason score of 7 can be derived from differing primary and secondary grades, for example 3 and 4, or 4 and 3. This can be significant because a primary grade of 3 indicates that the predominant Most tumors demonstrate two histologic patterns and this is expressed as a Gleason score. The two most common grade patterns seen in a tumor are expressed together and summed. Gleason scores can be expressed as their individual components or as the total Gleason score, eg 3+4=7. The highest a Gleason score can be is 10.

Authors Chantal Atallah 1 , Ants Toi 2 , Theodorus H van der Kwast 3 Affiliations 1 Département de While the new Gleason grade grouping (GGG), which started in 2016, has been widely validated in prostate cancer, it does not incorporate the concept of tertiary Gleason pattern 5. Furthermore, no study has “quantified” the individual risk of each Gleason pattern, including tertiary Gleason pattern 5, after radical prostatectomy. We reviewed 1022 men with adjuvant-treatment-naïve prostate a classification of adenocarcinoma of the prostate by evaluation of the pattern of glandular differentiation; the tumor grade, known as Gleason score, is the sum of the dominant and secondary patterns, each numbered on a scale of 1 to 5.

Gleason grade

The Gleason grading system is the most commonly used pathologic grading system for adenocarcinoma of the prostate (4).

Gleason grading, is the most commonly used system of classifying the aggressiveness of prostate cancer tissue. Based on how it looks under a microscope, a pathologist determines the level of aggressiveness on a scale from 1 to 5. Click to learn more about the Gleason Grade! We propose reporting Gleason grades, including prognostic grade groups which accurately reflect prognosis as follows: Gleason score ≤6 (prognostic grade group I); Gleason score 3+4=7 (prognostic grade group II); Gleason score 4+3=7 (prognostic grade group III); Gleason score 4+4=8 (prognostic grade group (IV); and Gleason score 9–10 (prognostic grade group (V).

This is given after a pathologist has examined under a microscope cancerous tissue obtained from the needle biopsy. The cells identified are given a grade number from 1 to 5, depending on the abnormality of the cells, 1 being the lowest, 5 the highest.
