Abstract:

OBJECTIVE: Esophageal squamous cell carcinoma (ESCC) is still the leading cancer-caused mortality in China,and 5-year survival remains poor. The aim of this study is to survey the ability that coexpression of Fascin and EGFR predicts ESCC prognosis. METHODS:We collected 189 formalin-fixed paraffin-embedded esophageal curative resection specimens,and then constructed tissue microarray. Immunohistochemistry (IHC) was used for detecting the co-expression of Fascin and EGFR. Statistical analyses were performed using SPSS 13.0 for windows. RESULTS:Our IHC results showed that positive rates of high-expression of Fascin and EGFR were 35.4% and 56.1%,respectively. Positive rate of co-expression of Fascin and EGFR was 29.5%. The Kendall’s tau-b correlation analysis indicated that EGFR expression was associated with regional lymph node metastasis. Positive rate of EGFR without regional lymph node metastasis was 49.6%,while it was 68.7% with regional lymph node metastasis,P=0.014. Kaplan-Meier survival analysis showed that high-expression of Fascin and EGFR were associated with poor survival,while co-expression of Fascin and EGFR presented poorer survival. Pearson’s rank correlation analysis illustrated that there was a significant correlation between Fascin and EGFR. The multivariate Cox stepwise regression analysis demonstrated that Fascin/EGFR coexpression was a passive independent poor prognostic factor for overall survival. The RR for patients with high-coexpression of Fascin/EGFR was 1.987 ,just a little higher than RR for high-expression of Fascin. The ROC curve analysis indicated that the specificity of the combination of Fascin and EGFR was more robust than that of a single biomarker. CONCLUSION:This study has successfully showed that co-expression of Fascin and EGFR could confer a poor prognosis.
