GLEASONUppdaterat den 15-05-2012 Gleason är sätt att gradera en prostatacancer. Graderingen görs med hjälp av cellernas mikroskopiska utseende i biopsin och patologen bestämmer graden genom att se på cellernas form och deras inbördes arrangemang. Patologen studerar cellernas så kallade differentiering. Gleasonsumma = den mest utbredda graden (primära) + den näst mest utbredda graden (sekundära). Observera att femprocentsregeln gäller för prostatektomier: eventuellt fokus av en tredje grad (tertiär grad) nämns separat i utlåtandet om denna är högre än de primära och sekundära (vanligen grad 4 eller 5).

Scores 2-5 are currently no longer assigned and certain patterns that Gleason defined as a score of 6 are now graded as 7, thus leading to contemporary Gleason score 6 cancers having a better prognosis than historic score 6 cancers. The Gleason grading system refers to how abnormal your prostate cancer cells look and how likely the cancer is to advance and spread.
