We found that MDSCs were more abundant in A-DLBCL than in ordinary DLBCL(P=0.039), with 33.8 ± 4.2/HPF vs 20.6 ± 4.1/HPF, represented by CD33, while M2 TAMs (CD163) and M1/M2 TAMs (CD68) showed no significant difference between A-DLBCL and ordinary DLBCL. Here, CD68 is linked to diffuse large B-cell lymphoma.
