Abstract: 目的探讨肺癌患者血清中可溶性CD44V6(sCD44V6)蛋白含量及活检癌组织中CD44V6蛋白表达的临床意义.方法应用酶联免疫吸附实验(ELISA)检测130例肺癌手术前后、32例健康人和116例随访病例血清中sCD44V6;应用生物素-抗生物素免疫组织化学法(ABC法),检测所有肺癌患者经内镜活检癌组织内CD44V6蛋白表达状况.结果肺癌患者血清中CD44V6含量(3.58±0.56)明显高于健康对照组(1.59±0.44),术前(3.58±0.56)高于术后(1.78±0.52),复发转移组(3.16±0.54)高于无复发转移组(1.29±0.61);肺癌活检组织CD44V6蛋白表达率69.23%,与肺癌T分期无关,N0期CD44V6蛋白阳性表达率57.65%,N1期CD44V6蛋白阳性表达率92.93%,两者差异有统计学意义(P＜0.01).结论血清中CD44V6含量及经内镜活检的肺癌组织中CD44V6蛋白表达与肺癌的转移复发有关,可作为一种可靠的判断手术疗效、预后及复发转移的临床检测指标.
