血浆M2-PK与血清CEA、ADAM8联合检测诊断非小细胞肺癌的临床价值研究

摘要

目的 研究血浆M2型丙酮酸激酶(M2-PK)、血清肿瘤标志物癌胚抗原(CEA)和血清解整合素样-金属蛋白酶8(ADAM8)检测在诊断非小细胞肺癌(non-small cell lung cancer,NSCLC)中的应用价值.方法 随机选择2014年4月～ 2016年8月期间笔者医院收治的75例NSCLC患者作为研究组,另外随机选择75例笔者医院健康的体检者作为对照组.采用酶联免疫吸附法(ELISA)检测所有研究对象患者的血清ADAM8和M2-PK水平,使用电化学发光法(ECLIA)检测所有研究对象的血清CEA水平.并使用ROC曲线分析比较M2-PK、CEA和ADAM8单独和联合检测诊断NSCLC的临床价值.结果 研究组患者M2-PK、CEA和ADAM8水平均显著高于对照组,差异有统计学意义(P＜0.05).腺癌组患者M2-PK、CEA水平明显高于鳞癌组患者,Ⅲ～Ⅳ期患者的M2-PK、CEA和ADAM8水平均明显高于Ⅰ～Ⅱ期患者,差异有统计学意义(P＜0.05).M2-PK、CEA、ADAM8联合检测诊断NSCLC的AUC(0.924)明显高于M2-PK、CEA、ADAM8单独检测(0.731、0.858、0.790),差异有统计学意义(P＜0.05).M2-PK、CEA和ADAM8联合检测NSCLC的敏感度和特异性均明显高于M2-PK、CEA和ADAM8单独检测组,差异有统计学意义(P＜0.05).结论 M2-PK、CEA、ADAM8检测诊断NSCLC具有一定的临床应用价值,且M2-PK、CEA、ADAM8联合检测诊断价值优于单独检测,值得临床推广使用.%Objective To study the clinical application value of plasma M2 pyruvate kinase (M2-PK),serum tumor marker carcinoembryonic antigen (CEA) and serum level of integrin-like protein-8 (ADAM8) in the diagnosis of Non-small cell lung cancer (NSCLC).Methods Seventy-five patients with NSCLC admitted to our hospital from April 2014 to August 2016 were randomly selected as study group.Seventy-five healthy subjects were randomly selected as control group.Serum ADAM8 and M2-PK levels were measured by enzyme-linked immunosorbent assay (ELISA) in all subjects,and serum CEA levels were determined by electrochemiluminescence (ECLIA).The clinical value of M2-PK,CEA and ADAM8 in diagnosis of NSCLC were analyzed by ROC curve.Results The levels of M2-PK,CEA and ADAM8 in the study group were significantly higher than those in the control group (P ＜ 0.05).The levels of M2-PK and CEA in patients with adenocarcinoma were significantly higher than those in squamous cell carcinoma patients (P ＜0.05),and the levels of M2-PK,CEA and ADAM8 in stage Ⅲ-Ⅳ patients were significantly higher than those in stage Ⅰ-Ⅱ patients (P ＜ 0.05).The AUC of M2-PK,CEA and ADAM8 combined detection (0.924) was significantly higher than that of M2-PK,CEA and ADAM8 separate detection (0.731,0.858 and 0.790),and the difference was statistically significant (P ＜ 0.05).The sensitivity and specificity of M2-PK,CEA and ADAM8 combined detection were significantly higher than those of M2-PK,CEA and ADAM8 separate detection (P ＜ 0.05).Conclusion The value of M2-PK,CEA and ADAM8 in diagnosing NSCLC has a certain clinical value,and the diagnostic value of M2-PK,CEA and ADAM8combined detection is superior to that of separate detection,and M2-PK,CEA and ADAM8 combined detection worthy of clinical application.
