多发性浅表膀胱移行细胞癌中VEGF的表达及意义

目的:探讨单发性和多发性浅表膀胱移行细胞癌组织中血管内皮生长因子(VEGF)的表达及意义。方法:采用免疫组化方法对60例浅表膀胱移行细胞癌组织及10例正常膀胱组织进行血管内皮生长因子(VEGF)的检测,观察单发性和多发性浅表膀胱移行细胞癌组织中VEGF表达的关系。结果:多发性浅表膀胱移行细胞癌VEGF的高表达明显高于单发者的高表达;VEGF高表达的浅表膀胱移行细胞癌的患者的复发率明显高于低表达者的复发率。结论:VEGF表达的高低与浅表膀胱移行细胞癌的生物学行为有关。

Vascular endothelial growth factor expression in superficial transitional cell bladder carcinoma

AIM: To study the expression of the VEGF in single and multiple superficial transitional cell bladder carcinoma and their clinical significance. METHODS: Immunohistochemical method was used to study the VEGF in 60 cases of superficial transitional cell bladder carcinoma and in 10 cases of normal bladder tissue as control. RESULTS: High expression of VEGF in bladder carcinoma cell was observed. The expression level of VEGF in multiple superficial transitional cell bladder carcinoma was higher than that in single superficial transitional cell bladder carcinoma. The recurrent rate in the patient with VEGF high expression was more than that in the patient with VEGF low expression. CONCLUSION: The expression level of VEGF was correlated to the biological behavior of superficial transitional cell bladder carcinoma.
