肿瘤型M2丙酮酸激酶表达水平与非小细胞肺癌患者近期疗效及预后的关系

目的 探讨非小细胞肺癌(NSCLC)患者治疗前后血浆中肿瘤型M2丙酮酸激酶(TuM2-PK)的表达水平及其与肿瘤的近期疗效及预后的关系.方法 用ELISA法分别检测83例NSCLC患者(其中31例NSCLC患者手术治疗,52例患者失去外科手术机会而行内科治疗)和106例健康对照者血浆中的TuM2-PK表达水平,并进行24个月的随访.结果 NSCLC手术后血浆TuM2-PK浓度(13.5 U/ml)与术前(25.4U/ml)相比,差异有统计学意义(P<0.05).经内科治疗后,缓解组血浆TuM2-PK浓度(11.5 U/ml)与治疗前(22.6 U/ml)相比显著下降(P<0.05);进展组血浆TuM2-PK浓度(60.8 U/ml)与治疗前(23.7 U/ml)相比显著升高(P<0.05);稳定组血浆TuM2-PK浓度治疗前后差异无统计学意义(P>0.05).手术后TuM2-PK阳性率显著下降,而化疗后阳性率下降不明显.在随访期间,手术后TuM2-PK阳性患者肿瘤复发或转移率(67%,6/9)高于术后阴性患者(5%,1/20).结论 检测NSCLC患者血中肿瘤标志物TuM2-PK表达水平对预测肿瘤微转移有一定的临床意义,有助于疗效的评估以及预后的预测.

Correlation between the levels of tunlor type M2 pyruvate kinase with treatment response and prognosis in patients with non-small cell lung cancer

Objective To study the expression of tumor type M2 pyruvate kinase(tumor M2-PK) in nonsmall cell lung cancer (NSCLC) and their correlation with treatment response and prognosis.Methods The concentration of tumor M2-PK in plasma was detected by ELISA in 106 healthy controls and 83 NSCLC patients.The patients were followed for 24 months.Results The patients after surgical operation showed marked reduction in plasma tumor M2-PK level(13.5 U/ml vs 25.4 U/ml,P
