Individual patients B-cell location in prostatectomy specimens. The B-cell densities (mm²) were measured after CD20 staining of radical prostatectomy and computer generated values of area of staining was divided by area analyzed. This density was calculated within the tumor and outside the tumor and the difference was compared using the paired t-test. Each dot represents an individual patient’s intra-tumoral B-cell density minus their extra-tumoral B-cell density to display the magnitude of difference in B-cell location per patient.
