联合检测肿瘤 M2型丙酮酸激酶、TPS 及 CEA 对结肠癌的诊断价值

摘要

目的：探讨联合检测肿瘤 M2型丙酮酸激酶（Tumor M2-PK）、组织多肽特异性抗原（TPS）及癌胚抗原（CEA）对结肠癌的诊断价值。方法收集74例结肠癌患者和60例健康志愿者分别检测血清 TPS、CEA 和粪便中 Tumor M2-PK 水平，对比分析 TPS、CEA 及 Tumor M2-PK 单一检测及联合检测的灵敏度、特异度及准确性。结果结肠癌观察组肿瘤标志物 TPS、CEA 及Tumor M2-PK 水平均明显高于健康对照组（P ＜0．05）。3种肿瘤标志物的灵敏度、特异度及准确性在单一检测及联合检测的差异均有统计学意义（P ＜0．05）。3种肿瘤指标单一检测、单一检测与联合检测之间比较，特异度及准确性均低于三者联合。结论肿瘤标志物 TPS、CEA 及 Tumor M2-PK 联合检测可提高对结肠癌诊断的灵敏度、特异度及准确性。%Objective To explore the clinical value of the combined detection of tumor type M2 pyruvate kinase (tumor M2-PK),tissue polypeptide specific antigen (TPS)and carcino-embryonic antigen (CEA)in the diagnosis of colorectal cancer.Methods The serum level of TPS and CEA,and the level of tumor M2-PK in fecal were detected in 74 patients with colorectal cancer and 60 healthy volunteers in our hospital.The sensitivity,specificity and accuracy were performed the comparative analysis between the single detection and the combined detection.Results The serum levels of TPS,CEA and the level of tumor M2-PK in fecal in the colorectal cancer observation group were significantly higher than those in the healthy control group (P <0.05).There were signifi-cant differences in the sensitivity,specificity and accuracy of TPS,CEA and tumor M2-PK between and the combined detection (P <0.05).In the comparison among the single detection of 3 tumor markers and between the single marker detection with the combined detection,the sensitivity,specificity and accuracy of any single marker measurement was lower than that in the combined detection of 3 markers.Conclusion The combined detection of TPS,CEA and tumor M2-PK can improve the sensitivity,specificity and accuracy in diagnosing colorectal cancer.
