喉癌组织血管内皮生长因子的表达与喉癌临床病理关系

目的 :探讨血管内皮生长因子 (VEGF)的表达与喉鳞状细胞癌的临床病理关系。方法 :采用SP免疫组织化学染色技术 ,评价 87例喉鳞癌患者的肿瘤组织中VEGF的表达和微血管计数 (MVC)。资料分析采用SAS软件。结果 :在喉鳞状细胞癌中 ,VEGF的免疫反应主要发生于肿瘤细胞的胞浆内 ,其阳性率为 77.0 %。肿瘤侵犯范围越广 ,VEGF的表达越强 ,肿瘤侵犯范围越小 ,VEGF的表达越弱 (P <0 .0 5 ) ;肿瘤分化越差 ,VEGF的表达越强 ,肿瘤分化越好 ,VEGF的表达越弱 (P <0 .0 5 ) ;VEGF的表达越强 ,MVC越多 ,二者呈明显的正相关(P <0 .0 1) ,且肿瘤组织中的平均MVC明显高于切缘组织中的平均MVC(P <0 .0 1)。结论 :在喉鳞状细胞癌中 ,VEGF的表达与肿瘤的临床分期和分化明显相关 ,与MVC存在着明显的正相关 ,提示VEGF在喉鳞状细胞癌的进展中具有重要的作用

Relation between vascular endothelial growth factor expression and clinical pathological character in laryngeal squamous cell carcinoma

OBJECTIVE: To approach the relation between vascular endothelial growth factor (VEGF) expression and clinical pathological character in laryngeal squamous cell carcinoma. METHOD: Immunohistochemical staining (SP) was used to evaluated the expression of VEGF and microvessel count (MVC) in tumor tissues from 87 patients with laryngeal squamous cell carcinoma. RESULT: VEGF immune response was mainly localized to the tumor cell cytoplasm, positive rate was 77%. In laryngeal squamous cell carcinoma, the wider the tumor invaded, the stronger VEGF expressed, the fewer the tumor invaded, the weaker VEGF expressed (P < 0.05); The lower the tumor differentiated, the stronger VEGF expressed, the higher the tumor differentiated, the weaker VEGF expressed (P < 0.05); The stronger VEGF expressed, the more MVC were (P < 0.01); The mean MVC in tumor tissues was obviously higher than that in surgical margin tissues (P < 0.01). CONCLUSION: In laryngeal squamous cell carcinoma, the expression of VEGF was markedly correlated with tumor stage and differentiation, was positively correlated with MVC. As a result, VEGF may have an important role in the progression of laryngeal squamous the carcinoma.
