血清肿瘤标记物在肺癌诊断中的意义

open access: yesZhongguo shiyan zhenduanxue, 2014
目的探讨血清肿瘤标记物癌胚抗原(CEA)、肿瘤相关抗原199(CA199)、肿瘤相关抗原125(CA125)、神经特异性烯醇化酶(NSE)水平及联合检测在肺癌诊断中的价值。方法采用电化学发光法检测174例肺癌患者血清CEA、CA199、CA125和NSE水平,并与99例肺良性病变患者、42例健康体检者作对照,分析血清肿瘤标记物CEA、CA199、CA125和NSE在肺癌诊断中的价值。结果①肺癌组患者血清CEA、CA199、CA125和NSE水平明显高于肺良性病变组、健康体检组(P0.05);②CEA ...

血清肿瘤标志物对胃癌诊断及预后判断的临床意义

open access: yesZhongguo shiyan zhenduanxue, 2010
目的探讨血清肿瘤标志物癌胚抗原(carcinoembryonic antigen,CEA)、糖链抗原125(carbohydrate antigen125,CA125)、糖链抗原199(carbohydrate antigen 199,CA199)对胃癌诊断及预后判断的临床意义。方法采用电化学发光法测定78例胃癌患者、52例良性胃病者、47例健康人血清中CEA、CA125、CA199的水平,比较三组间及胃癌不同分期患者间的差异。结果胃癌组血清CEA、CA125、CA199均水平高于良性胃病组及健康对照组(
