High density of CD163-positive (M2) TAMs is a poor prognostic factor in DLBCL.
Immunohistological staining was performed on tissue samples from DLBCL patients at various disease stages. (A) Representative images of immunohistological staining for CD163. Scale bar = 100 μm. (B) Statistical analysis showed the distribution of the percentage of the CD163-positive staining area in samples at various disease stages. (C) Statistical analysis showed the correlation of the IPI and percentage of the CD163-positive staining area. **P < 0.01.
