摘要 目的观察乳酸脱氢酶(LDH)在非小细胞肺癌(NSCLC)患者血清中的表达情况及临床意义。方法检测84例NSCLC患者和18例肺部良性肿瘤患者血清中LDH的表达水平。对NSCLC患者血清LDH的表达与临床病理因素及预后的关系进行统计学分析。结果 84例NSCLC患者血清LDH水平高于18例肺部良性肿瘤患者[(351±119)U/L vs(183±56)U/L,P<0.01)。NSCLC患者血清中LDH的水平与患者的年龄、性别、病理类型差异无统计学意义(均P>0.05)。但是LDH的表达与淋巴结转移(r=0.225,P=0.041)、远处转移(r=0.187,P=0.048)、Ki-67阳性率(r=0.312,P=0.021)、TNM分期(r=0.276,P=0.037)呈正相关关系。LDH>300 U/L者3 a生存率低于LDH≤300U/L者(12.8%vs 31.1%,P<0.05)。结论LDH的表达与NSCLC患者的侵袭转移有一定关系,可作为判断其转移和预后的辅助指标。
