摘要 目的探讨98例膀胱癌患者尿液中癌胚抗原(CEA)、癌抗原19-9(CA19-9)、CD44联合检测对膀胱癌患者的诊断价值。方法膀胱癌患者98例,其他肿瘤患者39例,健康者78例作为对照组,采用放射免疫分析法测定膀胱癌患者尿液中CEA,CA19-9的浓度,免疫组织化学SP法测定膀胱癌患者膀胱癌组织中CD44的表达,通过统计学分析评价CEA单独检测和联合检测对于膀胱癌的诊断价值。结果膀胱癌组患者CEA和CA19-9水平分别为(128.7±69.02)、(97.66±29.51)U/mL。对照组人群CEA和CA19-9水平分别为(2.51±2.16)、(29.9±2.379)U/mL。以对照组检测值的±1.96s为临界点,即以CEA水平大于5.9U/mL和CA19-9水平大于27.1U/mL为阳性。单检阳性率CEA为78.83%,CA19-9为62.78%,CD44为40.87%;二联检阳性率中CEA、CA19-9二联检阳性率为81.75%,CEA、CD44二联检阳性率为75.18%,与CEA单检比较差异均有统计学意义(P<0.05);CEA、CA19-9、CD44三联检阳性率为86.13%,与CEA单检比较差异有统计学意义(P<0.05)。结论尿液CEA、CA19-9浓度和膀胱组织CD44表达情况三者联合检测可显著提高对早期膀胱癌诊断的阳性率,减少误诊,即阳性诊断成阴性,阴性诊断成阳性,以及漏诊,对提高早期诊断和及早进行疾病治疗,延长患者的寿命有重要价值。
