76例NSCLC组织中CAIX、VEGF和Ki67表达阳性率分别为46.1%、72.4%和39.5%;肺癌组织中CAIX表达明显高于炎性假瘤组(P<0.001);CAIX蛋白阳性表达率在鳞癌组和腺癌组表达分别为69.7%和27.9%(P=0.001);在接受放疗的34例患者中,CAIX阳性组和阴性组放疗客观反应率分别为27.8%和62.5%(P=0.042);CAIX蛋白表达与VEGF表达呈正相关(r=0.231, P=0.043),但与Ki67表达无相关性(r=0.064, P=0.583)。. This evidence concerns the gene VEGFA and non-small cell lung carcinoma.
