1、血管内皮生长因子-C表达与临床Ⅰ期非小细胞肺癌淋巴结转移和化疗的关系【摘要】目的探讨临床I期(cI期)非小细胞肺癌(NSCLC)中血管内皮生长因子C(VEGF-C)的表达、微淋巴管密度(MLVD)、淋巴结转移及其与化疗的关系。方法应用免疫组化SP法检测cI期NSCLC癌组织、癌旁组织及正常肺组织中VEGF-C的表达,计数MLVD,检测血清VEGF-C蛋白含量,并结合病理淋巴结转移情况和化疗前、后VEGF-C蛋白含量的变化进行统计学分析。结果在NSCLC中,VEGF-C呈过度表达,与癌旁组织和正常肺组织相比差异有统计学意义(P<0.01);在癌
2、组织中淋巴结阳性组和淋巴结阴性组的VEGF-C阳性表达率(91.9%vs.76.7%)、MLVD[(20.0±4.8)vs.(10.6±2.2)]差异有统计学意义(P<0.01);血清VEGF-C蛋白含量与组织检测VEGF-C具有较好的相关性(r=0.848,P<0.01),化疗患者化疗前血清VEGF-C蛋白含量(237±72.3)ng/mL较化疗后(178±69.2)ng/mL变化明显(P<0.01)。结论VEGF-C在cI期NSCLC中过度表达与淋巴结转移密切相关;血清VEGF-C蛋白含量测定是一种有效的VEGF-C检测方
