【摘要】 目的探讨CA15-3、CA125、CEA 3项肿瘤标志物联合检测对乳腺癌早期诊断和鉴别诊断的意义。方法采用电化学发光免疫分析技术(ECLIA)检测78例乳腺癌患者血清中CA15-3、CA125、CEA等肿瘤标志物的含量,并统计其阳性检出率。结果乳腺癌患者血清中CA15-3、CA125、CEA的含量分别为(78.75±51.28)IU/mL(、55.49±23.65)IU/mL、(30.17±12.15)μg/L,阳性率分别为77.94%,38.23%,41.17%,敏感性和特异性分别为77.94%和95.63%,38.23%和89.57%,41.17%和93.91%。3项指标联合检测的敏感性和特异性为90.76%和96.83%。结论CA15-3、CA125、CEA等肿瘤标志物联合检测能提高乳腺癌早期诊断和鉴别诊断的敏感性,同时又有较好的特异性,是一组效果较为理想的联合指标,具有一定的临床应用价值。更多还原

【Abstract】 Objective It is to discuss the significance of CA15-3, CA125 and CEA combined detected on early diagnosis and differential diagnosis of breast cancer.Methods Serum levels of CA15-3,CA125 and CEA in 78 patients with breast cancer were measured with ECLIA and their positive rate was counted.Results The serum levels of CA15-3,CA125 and CEA in 78 patients with breast cancer were respectively(78.75±51.28) IU/mL,(55.49±23.65) IU/mL and(30.17±12.15) μg/L.The positive rates were respectively 77.94%,38.23% and 41.17%.The sensitivities and specificities were respectively 77.94% and 95.63%,38.23% and 89.57%,41.17% and 93.91%.The sensitivity and specificity of combined determination of three indexes were 90.76% and 96.83%.Conclusion CA15-3,CA125 and CEA combined detected not only can increase the sensitivity of early diagnosis and differential diagnosis of breast cancer,but also has better specificity.CA15-3,CA125 and CEA are ideal combined indexes and have definite clinical application value.更多还原
