CLIN CHEM LAB MED:人类绒毛膜促性腺激素(hCGt)肿瘤标记物检测的可比性如何?

人类绒毛膜促性腺激素(hCGt)总肿瘤标志物测试被认为是没被临床试验认可的检测方法。我们比较了四种需要进行hCGt肿瘤标记物检测的患者。我们假设,如果恶性肿瘤相关的hCG分子形式的检测方法之间存在差异,则肿瘤标记物的回归斜率将发生变化,并且与妊娠样品相比,离群值更常见。此外,这种系统性差异将显而易见,并且足以改变临床管理决策。

我们在137位女性和253位男性中的390个样本中通过TotalβhCG,ArchitectTotal-βhCG,Cobas hCG h +β和Immulite HCG方法测量了hCGt。肿瘤标志物与妊娠标本的方法回归无显著性差异。男性和女性肿瘤标志物和妊娠组的离群率相似:1.6%(95%置信区间[CI] 0%-3.1%), 2.2%(95%置信区间0%-4.7%)和2.9%(95%置信区间0.6%-5.2%)。这些异常值是随机分布的,它们不会对临床决策产生不利影响。

研究结果表明,hCGt结果在临床上是相同的,四种方法之间没有系统性差异。
