CD68 and cancer: In all cancer patients, we found a significant increase in macrophage (CD68+, n) (128 ± 72) and lymphocyte (CD3+, n) (6 ± 4) infiltration of the SAT with respect to controls (52 ± 36 and 2 ± 2, respectively) (P < 0.0001), without significant difference in the number of B lymphocytes (CD20+) (median 4, IQR 1–8 vs. median 1, IQR 1–9) between the two groups.
