[摘要] 目的 研究微血管密度(microvessel density,MVD)和血管内皮生长因子(vascular endothelial growth factor,VEGF)在口腔鳞癌中的表达,探讨其与预后关系。 方法 采用SABC免疫组织化学染色方法检测56例口腔鳞癌中MVD和VEGF的表达,采用SPSS软件行统计分析。结果 51.8%口腔鳞癌组织呈VEGF阳性表达。VEGF表达阳性的口腔鳞癌组织MVD显著高于VEGF表达阴性者(P<0.05)。
VEGF表达与肿瘤的分化程度、淋巴结转移密切相关,而与肿瘤的临床分期无关。VEGF阴性表达的病人术后5年生存率较阳性表达者高。MVD记数与肿瘤的分化程度、淋巴结转移及临床分期密切相关。口腔鳞癌患者MV
D高记数组较低记数组预后差。 结论 口腔鳞癌组织VEGF表达与微血管密度有明显的相关性,是口腔鳞癌主要的新生血管诱导因子之一,VEGF、MVD可做为口腔鳞癌预后的一个有效指标。

[Abstract] Objective To evaluate the clinical significance of microvessel density(MVD) and vascular endothelial growth factor(VEGF) expression in oral squamous cellcarcinomas. Methods unohistochemical staining(SABC) was used to quantify MVD and VEGF expression in specimens from 56 patients with oral squamous cell carcinomas.SPSS
statistical software was used. Results: VEGF expression was observed in 29 of the patients(51
