Results on T-cell infiltrates determined by immunohistochemistry in A20 lymphomas following different treatment combinations (Y-axis represents mean counts/high-power field). CD3+ (left columns) and CD8+ counts (right columns) changed in parallel. Treatment by CHOP alone resulted in a significant increase in the immune infiltrate (p < 0.05), which was strongly intensified by the adjuvant AA treatment (p < 0.05 for both values). Extended AA (AAx5) did not further improve the extent of lymphocytic infiltration (p = 0.188 and 0.32).
