To study the expression and regulatory effects of CD146 protein in colorectal cancer and the correlation between CD146 protein expression and the prognosis of colorectal cancer.


The CD146 protein level was detected by immunohistochemistry staining. The relationship between CD146 expression and clinicopathological parameters of colorectal cancer was determined.


It was observed that 216 (20.00%) of the 1080 cases positively expressed CD146 protein. Univariate analyses indicated that CD146 expression was related to histological grade, Duke's stage, and liver metastasis (p=0.001, 0.001, and 0.001, respectively). Spearman correlation analysis showed that CD146 expression has line correlation to histological grade, Duke's stage, and liver metastasis (p=0.02, 0.01 and 0.001, respectively). After multivariate analysis, Duke's stage and CD146 were related to liver metastasis (p=0.01 and 0.001, respectively). In the Cox regression test, histological grade, Duke's stage, and CD146 were detected as the independent prognostic factors (p=0.045, 0.01, and 0.001, respectively).


CD146 protein may be a potential biomarker for the postoperative liver metastasis of colorectal cancer.
