ABSTRACT
CD146, a cell adhesion molecule, is found in normal and tumor tissues. The level of its expression has been found to directly correlate with tumor progression and metastatic potential. The objective of this study was to investigate the expression of CD146 in esophageal squamous cell carcinoma (ESCC) and its correlation with clinicopathological parameters. Tumor specimens were collected from 63 patients with ESCC who underwent complete resection. We analyzed the CD146 expression levels in ESCC by immunohistochemistry. The expression of CD146 was detected and it was observed to correlate with clinicopathological parameters. Sixty-three cases of normal squamous mucosa were included for comparison. CD146 expression was identified in 46.0% (29/63) of the ESCC samples, and no positive (weak to moderate or moderate to strong) expression was found in the normal squamous epithelium samples (χ²=27.248; P<0.0001). CD146 expression was associated with lymph node metastasis (χ²=5.117; P=0.024) and advanced clinical stage (χ²=4.661; P=0.031). CD146 expression was one of the significant predictors of survival (hazard ratio, 2.838; 95% confidence interval 1.102-7.305). The overexpression of the CD146 gene was one of the important phenotypes and characteristics in ESCC carcinomatous change. We found that CD146 expression was associated with lymph node metastasis and advanced clinical stage, and was an indicator of poor prognosis in ESCC patients. CD146 may prove to be an important tumor marker for the individualized treatment for ESCC.
