目的：评价血清同工铁蛋白在鼻咽癌中的诊断价值。材料与方法：采用酶联免疫双抗体夹心法观察３０例鼻咽癌患者及８４例健康人同工铁蛋白（ＳＩＦ）水平。结果：鼻咽癌患者血清同工铁蛋白与正常人有显著性差异（Ｐ＜０．０１）。血清同工铁蛋白对鼻咽癌有较高的敏感性（８０％）、特异性（９７．８％）和准确性（９３％）。结论：血清同工铁蛋白在鼻咽癌诊断中有重要价值。
Objective: To evaluate the diagnostic value of serum homosfungin in nasopharyngeal carcinoma. MATERIALS AND METHODS: Thirty human nasopharyngeal carcinoma patients and 84 healthy volunteers were enrolled in this study. Results: There was a significant difference between serum homokinin and normal subjects in NPC patients (P <0.01). Serum homo-ferritin has a higher sensitivity (80%), specificity (97.8%) and accuracy (93%) for NPC. Conclusion: Serum isoenzyme is of great value in the diagnosis of nasopharyngeal carcinoma.
