摘要 目的观察非小细胞肺癌组织中血管内皮生长因子(VEGF)与色素上皮衍生因子(PEDF)的表达变化,并探讨其意义。方法采用免疫组化法对50例非小细胞肺癌组织中的VEGF、PEDF进行检测,以CD31标记免疫组化法检测微血管密度(MVD)。结果 VEGF、PEDF在肺癌组织中的阳性表达率分别为64%、44%,二者的表达呈负相关(r=-0.599,P<0.01)。MVD值在PEDF阴性组高于阳性组(P<0.05),在VEGF阳性组则高于阴性组(P<0.05)。VEGF和PEDF的表达与肺癌远处转移、分化程度、临床分期有关(P均<0.05)。结论在非小细胞肺癌组织中VEGF、PEDF的表达有相关性,且与MVD关系密切,PEDF可能通过抑制MVD生成而起抑癌作用;检测VEGF和PEDF有助于肺癌远处转移、分化程度、临床分期的判断。
