Abstract:
Background: To evaluate the expression and clinicopathological significance of a disintegrin and metalloproteinases 19 (ADAM19) CUE domain containing protein 2 (CUEDC2) in extrahepatic cholangiocarcinoma (EHCC). Materials & methods: Immunostaining of ADAM19 and CUEDC2 was performed by EnVision immunohistochemistry in benign and malignant biliary tract tissues. Result: The expression of ADAM19 and CUEDC2 were significantly higher in EHCC (p < 0.05). ADAM19 expression was positive correlated with CUEDC2 expression in EHCC (p < 0.05). The overall survival time of those with positive expression of ADAM19 and CUEDC2 was lower (p < 0.001). Both positive expression of ADAM19 and CUEDC2 were independent prognostic factors in EHCC. Conclusion: ADAM19 and CUEDC2 have a positive correlation to the pathogenesis and dismal prognosis in EHCC.
