目的：探讨血管内皮生长因子（ VEGF ）、P53及Ki-67在食管鳞状细胞癌发生、发展中的作用。方法采用免疫组织化学染色SP法检测43例食管鳞状细胞癌组织和20例食管癌旁组织中VEGF、P53及Ki-67表达。结果VEGF蛋白、P53及Ki-67在食管鳞状细胞癌中阳性率分别为90．7％、88．4％、100．0％，而在癌旁组织中低表达及不表达，2组比较P均＜0．01；VEGF、P53及Ki-67阳性表达与临床病理特征之间关系研究发现VEGF、P53及Ki-67表达强弱与癌组织分化程度（γ＝0．945、0．963、0．986，P均＜0．05）呈正相关。结论 VEGF、P53及Ki-67在食管鳞状细胞癌组织中的表达显著升高，其可能与食管鳞状细胞癌的发生、发展密切相关。%Objective To investigate the effect of vascular endothelial growth factor (VEGF),P53 and Ki-67 in the oc-currence and development of esophageal squamous cell carcinoma .Methods Expression of VEGF ,P53 and Ki-67 in 43 cases of esophageal squamous cell carcinoma and 20 cases of adjacent cancer tissues were detected by immunohistochemistry SP method . Results In esophageal squamous cell carcinoma ,positive rates of VEGF protein ,P53 and Ki-67 were 90.7%,88.4%,100.0%. In the adjacent cancer tissues ,VEGF protein,P53 and Ki-67 had low expression or no expression ,P<0.01:The relationship be-tween clinicopathologic features and expression of VEGF , P53 and Ki-67 showed that expression of VEGF , P53 and Ki-67 was positively related with tumor differentiation (γ=0.945,0.963,0.986,P<0.05).Conclusion The dramatic increase of VEGF, P53 and Ki-67 in esophageal squamous cell carcinoma may be closely related to the occurrence and development of esophageal squamous cell carcinoma .
