Gleason score 3+4=7 (prognostic grade group II) indicating the majority is pattern 3; Gleason score 4+3=7 (prognostic grade group III) where pattern 4 is dominant; [6] Gleason score 4+4=8 (prognostic grade group IV); Gleason scores 9-10 (prognostic grade group V). [7] Prostate cancers with a Gleason score ≤ 6 usually have rather good prognoses.
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based on Gleason score of 2–4, 5–6, and 7–10, respectively, persists in SEER and other databases but is generally outdated.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 pathologists rarely assign a tumor a grade less than 3, particularly in biopsy tissue.
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 favored treatment option depends on the stage of the disease, the Gleason score, and the PSA level. Other important factors include the man's age, his general health, and his feelings about potential treatments and their possible side-effects.
The 4Kscore combines total, free and intact PSA together with human kallikrein 2. [46] It is used to try to determine the risk of a Gleason score greater than 6. [46] The Prostate Health Index (PHI) is a PSA-based blood test for early prostate cancer screening. It may be used to determine when a biopsy is needed. [32] [46]
In a separate study of men from the pre prostate cancer screening era managed with watchful waiting (56% over age 70 years), progression to distant metastasis or prostate cancer death was 13.9% and 12.3%, respectively for Gleason score 6 or below, but considerably higher at 18.2 and 22.7%, 30% and 20%, 44.4% and 55.6% for Gleason 3+4, 4+3, and ...
