Fig. 2From: Immune cell concentrations among the primary tumor microenvironment in colorectal cancer patients predicted by clinicopathologic characteristics and blood indexesCorrelations between the CEA level, number of monocytes, LMR, ApoA1 and density of immune cells in the tumor microenvironment. a The density of CD8+ T cells in the core of the tumor showed a tendency that correlated with the level of CEA in the blood, with a coefficient of − 0.135 (P = 0.037). b The density of CD3+ T cells in the core of the tumor was significantly related to the LMR, with a coefficient of 0.135 (P = 0.038). c The density of CD3+ T cells in the core of the tumor showed a tendency that correlated with the number of monocytes in the blood, with a coefficient of − 0.127 (P = 0.052). d The densities of CD3+ T cells in the core of the tumor showed a tendency that correlated with ApoA1, with a coefficient of 0.127 (P = 0.051). e The densities of CD3+ T cells in the invasive margin were correlated with ApoA1, with a coefficient of 0.169 (P = 0.010)Back to article page
