Expression of tenascin and CD34 in human esophageal squamous cell carcinoma / 中华胸心血管外科杂志

ABSTRACT

Objective To investigate the expressions of tenascin(TN)and microvessel density(MVD) in esophageal squamors cell carcinoma.Methods The experessions of TN and MVD were observed by immunohistochemiccal methods in 91 cases of esophageal carcinoma and 47 cases of ono-esophageal carcinoma.Results ①The expression of tenascin in esophageal cancer was much high than that in t he normal tissue(t=12.331,P＜0.01).②Over expression of TN was related to th length(F=12.373,P＜0.01),the invasion(F=11.039,P＜0.01),the lymphatic metastasis(F=6.882,P=0.01)and the pathologic trade(F=5.060,P=0.003)of cancer.③The expression fo MVD in the esophageal carcinoma tissues was stonger than that in the nonesophageal carcinoma tissues(t=6.023,P＜0.01).④Over expression of NVD wsa related to the length(F=9.033,P＜0.01),the lymphatic metastasis(F=12.429,P＜0.01)and the pathologic grade(F=5.717,P＜0.01)of cancer.⑤The positive expressions of TN and MVD were associated(P=0.001).Conclusion TN;s voerexpressions may be a biological marker in esophageal squamous cell carcinoma..It was associated with the expression of MVD.The levels of TN and NVD were useful molecular markers for evaluating malignancy degree and lymph node metastasis of esopageal carcinoma.
