摘要
方法 选取河北医科大学第一医院4845名健康成人和190名肺癌患者作为研究对象，采用化学发光法测定Cyfra21-1和CEA的含量，以确定当地筛查人群Cyfra21-1和CEA的参考区间。结果 Cyfra21-1和CEA的参考值上限分别为3.19 ng/ml和3.13 ng/ml。值得注意的是，男性的 Cyfra21-1 和 CEA 水平均高于女性。结论我们的研究表明，本地人群中 Cyfra21-1 和 CEA 的参考区间与既定的参考区间存在差异。此外，这两种生物标志物都表现出性别差异，并与年龄呈正相关。将这两种生物标志物结合起来，有望提高肺癌的诊断率。
Reference intervals of Cyfra21-1 and CEA in healthy adult Han Chinese population
Objective
This study aimed to establish the reference intervals of Cyfra21-1 and CEA for the local screening populations using a chemiluminescence method.
Methods
A total of 4845 healthy adults and 190 lung cancer patients were included from the First Hospital of Hebei Medical University. The levels of Cyfra21-1 and CEA were measured to establish the local reference intervals.
Results
The upper limit reference intervals for Cyfra21-1 and CEA were determined as 3.19 ng/ml and 3.13 ng/ml, respectively. Notably, both Cyfra21-1 and CEA levels were found to be higher in males than in females. Additionally, both biomarkers showed an increasing trend with age.
In terms of diagnostic efficacy, the receiver operating characteristic (ROC) curve areas for Cyfra21-1, CEA, and their combination in lung cancer were 0.86, 0.73, and 0.91, respectively.
Conclusion
Our study revealed that the reference intervals of Cyfra21-1 and CEA in the local population differed from the established reference intervals. Furthermore, both biomarkers exhibited gender-dependent variations and demonstrated a positive correlation with age. Combining the two biomarkers showed potential for improving the diagnosis rate of lung cancer.
期刊介绍：
Practical Laboratory Medicine is a high-quality, peer-reviewed, international open-access journal publishing original research, new methods and critical evaluations, case reports and short papers in the fields of clinical chemistry and laboratory medicine. The objective of the journal is to provide practical information of immediate relevance to workers in clinical laboratories. The primary scope of the journal covers clinical chemistry, hematology, molecular biology and genetics relevant to laboratory medicine, microbiology, immunology, therapeutic drug monitoring and toxicology, laboratory management and informatics. We welcome papers which describe critical evaluations of biomarkers and their role in the diagnosis and treatment of clinically significant disease, validation of commercial and in-house IVD methods, method comparisons, interference reports, the development of new reagents and reference materials, reference range studies and regulatory compliance reports. Manuscripts describing the development of new methods applicable to laboratory medicine (including point-of-care testing) are particularly encouraged, even if preliminary or small scale.
