摘要:

目的 计算7项肿瘤标志物[甲胎蛋白(AFP)、癌胚抗原(CEA)、糖类抗原(CA)125、CA15-3、CA19-9、游离前列腺特异性抗原(f-PSA)、总前列腺特异性抗原(t-PSA)]的参考变化值(RCV)和参考变化因子(RCF)。方法 根据公式计算RCV及参考变化上限因子(RCFup)和参考变化下限因子(RCFdown)的单向范围和双向范围。结果 根据公式计算出AFP、CEA、CA125、CA15-3、CA19-9、f-PSA、t-PSA的RCV和RCF。结论 建议临床实验室同时使用RCV和RCF作为健康人群的参考区间。在连续监测肿瘤患者相关指标时将RCF作为临床动态判读的方法。

Abstract:

Objective To calculate the reference change values(RCV) and reference change factors(RCF) of 7 tumor markers [alpha-fetoprotein(AFP),carcinoembryonic antigen(CEA),carbohydrate antigen(CA)125,CA15-3,CA19-9,free prostate-specific antigen(f-PSA) and total prostate-specific antigen (t-PSA)]. Methods The unidirectional ranges and bidirectional ranges of RCV and RCF reference change upper limit factor(RCFup) and reference change lower limit factor(RCFdown) were calculated. Results The RCV and RCF of AFP,CEA,CA125,CA15-3,CA19-9,f-PSA and t-PSA were calculated according to the formulas. Conclusions It is recommended that clinical laboratories use both RCV and RCF as reference intervals for healthy subjects. RCF is used as a method for clinical dynamic interpretation when continuously monitoring related indicators of tumor patients.
