There were significant correlations between CD68 and CD163 (Pearson correlation r = 0.473, p < 0.001) or VEGF-A (Pearson correlation r = 0.574, p < 0.001) expression while CD68 expression was moderately correlated with VEGF-C (Pearson correlation r = 0.337, p < 0.001) expression in squamous cell carcinoma. The gene discussed is VEGFA; the disease is squamous cell carcinoma.
