2. Fig. 1
Impact of the Gleason pattern on patient prognosis (time to biochemical recurrence). (A) Gleason categories with Gleason 7 separated into 3+4 and 4+4; (B) further subdivision of Gleason categories 3+4 and 4+3 into cancers with low and high fractions of Gleason 4, with 3+4 low=≤25% Gleason 4, 3+4 high=26-49% Gleason 4, 4+3 low=50–74% Gleason 4 and 4+3 high=≥75% Gleason 4; and (C) “quantitative” Gleason with patient groups defined by the fraction of Gleason 4.
PSA=prostate specific antigen.

3. Fig. 2
Impact of the Gleason score in the biopsy on the likelihood of finding an unfavorable Gleason score in a subsequent prostatectomy specimen. Comparison of the Gleason in the biopsy and the radical prostatectomy based on (A) the worst Gleason found in all biopsies and (B) the average Gleason across all biopsies. (C) Same analysis as in A and B but with the average biopsy Gleason score being further subdivided according to the fraction of Gleason 4 into cancers with 3+4 low (≥25% Gleason 4), 3+4 high (25-49% Gleason 4), and 4+3 low (50–74% Gleason 4) or 4+3 high (75-94% Gleason 4). (D) Further subdividing of the biopsy Gleason score according to the fraction of Gleason 4 cancer cells. All analyses are statistically significant (p< each).
RPE=radical prostatectomy.

4. Fig. 3
Extra value provided by the average (quantitative) Gleason grade. Comparison of the quantitative Gleason score with the radical prostatectomy score in subsets of cancers with identical worst (maximal) Gleason score seen in the biopsy.
Max=maximum; RPE=radical prostatectomy.
