Consistent with the recently reported positive prognostic associations with plasma cell content, and the increased density of these cells in prostate tumors from BL patients (21), B cell content by IHC for CD79a was significantly negatively correlated with PGA in the overall Johns Hopkins cohort (as well as BL and WH subsets) (Supplemental Figure 11). The gene discussed is CD79A; the disease is Burkitt lymphoma.
