CD68 and colonic neoplasm: Of particular interest, CD68+ macrophages at the IM correlated with risk of death from colon cancer (39% (CI: 17–64) for high CD68+ versus 0% (CI: 0–19) for low CD68+, p = 0.008) whereas stromal CD20+ B cells at the TC correlated with risk of death from all causes (50% (CI: 25–75) for low CD20+ versus 13% (CI: 2–38) for high CD20+, p = 0.05).
