Objective:To investigate the expressions of fibroblast growth factor 19(FGF19) and fibroblast growth factor receptor 4 (FGFR4) in esophageal squamous carcinoma and normal esophageal tissues and their correlation. Methods:Immunohistochemical method was used to detect the FGF19 and FGFR4 protein expressions in 34 postoperative pathological specimens of esophageal squa-mous carcinoma in patients in our hospital from 2009-2012 and normal esophageal tissues. Statistics analysis was made after the de-tection. Results:FGF19 and FGFR4 expressions were high in esophageal squamous carcinoma(P=0.000,P=0.000). There was a posi-tive linear correlation between expressions of FGFR4 and FGF19 and lymph node metastasis(rs=0.401,P=0.019;rs=0.404,P=0.018) and pathological stage(rs=0.495,P=0.003;rs=0.439,P=0.009) in esophageal squamous carcinoma. Expressions of FGFR4 and FGF19 were in a positive linear correlation in the disease. Conclusions:FGF19 and FGFR4 proteins are correlated with esophageal squamous carcinoma and they participate in the process of invasion and metastasis.
