摘要 目的探讨非小细胞肺癌(NSCLC)中Beclin 1、LC3的表达情况及临床意义。方法通过免疫组织化学SP法检测72例NSCLC标本中Beclin 1、LC3的表达情况。结果 Beclin1、LC3在NSCLC中的阳性表达率(46.3%,43.9%)、癌旁组的阳性表达率(83.3%,91.7%)均低于肺正常组织(100%,100%),差异具有统计学意义(均P<0.05)。Beclin 1在NSCLC的表达与患者的年龄及临床分期有关(P=0.037;0.009)。LC3在NSCLC的表达与患者的临床分期和肿瘤分化程度有关(P=0.002;0.000);Beclin 1、LC3在NSCLC中的表达呈正相关(r=0.425,P=0.000)。结论Beclin 1、LC3在NSCLC中低表达,自噬活性的降低可能对肺癌的发生发展及侵袭转移起一定的作用。
