The standard approach for grading prostate cancer depends on a Gleason score, which is based on pathologic evaluation of a prostatectomy specimen and is commonly estimated from prostate biopsy tissue. Prostate cancer patterns are assigned a grade from 1 to 5; the score is created by adding the most common pattern and the highest-grade patterns. Grade 3 is indicated by distinctly infiltrative margins.
