The relationship between TLR9 expression in cancer tissues and the ratio of patients on increasing CEA (>5 ng/mL) in blood.

Notes: The curve-fitting statistical analysis was used in dealing with the relationship of TLR9 expression in cancer tissues and the ratio of patients on increasing CEA (>5 ng/mL) pre operation. The number in the diagram is the ratio of CEA (>5 ng/mL) corresponding to TLR9 expression score, becoming added with high expression of TLR9. Spearman correlation coefficient was 0.9643, and the P-value was 0.0028. The R² value of the curve using the correlation fitting method was 0.9786. This result illustrated that TLR9 signal activation emerged more easily in colorectal cancer with an abnormal increase in CEA.
