摘要 目的探讨血浆肿瘤型M2丙酮酸激酶(TuM2-PK)检测在直肠癌诊断中的价值。方法应用酶联免疫吸附试验(ELISA)检测153例直肠癌患者、48例直肠良性病变患者及32名正常对照者血浆TuM2-PK水平。以TuM2-PK>15 U/mL为阳性,分析直肠癌患者血浆TuM2-PK水平与临床病理参数的相关性。结果直肠癌组血浆TuM2-PK水平为(26.23±5.36)U/mL,明显高于直肠良性病变组[(18.52±3.66)U/mL]及正常对照组[(17.68±4.02)U/mL](P均<0.05),而直肠良性病变组与正常对照组之间差异无统计学意义(P>0.05)。直肠癌患者血浆TuM2-PK阳性率与肿瘤细胞分化程度、淋巴结转移与否及临床TNM分期有关。血浆TuM2-PK检测直肠癌的敏感性为62.09%、特异性为79.16%、阳性似然比为2.20、阴性似然比为0.49、阳性预测值为90.47%、阴性预测值为39.58%。结论血浆TuM2-PK对判断直肠癌的辅助诊断有较高的临床价值,对直肠癌的临床分期、浸润转移有一定的意义。
