鼻咽癌淋巴管和微血管同期检测与预后

目的:观察微血管和淋巴管密度在鼻咽癌中的分布特点,探讨其对鼻咽癌复发转移和预后的意义。方法:对106例鼻咽癌患者的组织标本,采用微血管和淋巴管特异性标记物CD34和D2-40同期进行免疫组化检测,通过计算机辅助图像分析系统定量分析肿瘤周边及中心区域微血管和淋巴管分布状况,跟踪随访36～45个月,分析其与鼻咽癌复发转移和预后的关系。结果:106例鼻咽癌患者组织标本中,微血管和淋巴管染色均呈阳性表达,瘤周微血管和淋巴管密度均大于瘤内。单因素分析显示瘤内微血管密度、瘤内和瘤周淋巴管密度与鼻咽癌复发转移相关(P<0.05),而年龄、性别、T分期、N分期、临床分期,以及瘤周微血管密度与之不相关(P>0.05);多因素分析显示瘤内微血管密度和瘤周淋巴管密度是鼻咽癌复发转移的独立风险因素。瘤内微血管密度高表达与鼻咽癌的不良预后密切相关(P<0.05)。结论:微血管和淋巴管密度高表达是评估鼻咽癌预后不良的指标。瘤内和瘤周微血管、淋巴管在肿瘤复发转移中可能发挥着不同的作用,瘤内微血管和癌周淋巴管应成为鼻咽癌治疗的靶点。

Prognostic value of synchronized detection of microvascular and lymph vessel density in nasopharyngeal carcinoma

Objective:To investigate the distribution patterns of microvascular density(MVD) and lymph vessel density(LVD) in nasopharyngeal carcinoma,and to discuss their relationships with tumor recurrence-metastasis and prognosis.Method:One hundred and six patients with pathologically proved nasopharyngeal carcinoma were included in this study.Immunostainings for the vascular endothelial marker CD34 and the lymph vessel markerD2-40 were performed.The microvascular and lymph vessels within the tumor and the peritumor...
