１９９４年１月～１９９４年６月，从６２１名住院病人中用双盲法随机抽取２６例良性肿瘤和６３例恶性肿瘤，进行血清铁蛋白（ＳＦ）的测定，７３例健康献血员的ＳＦ作为对照组．结果显示，正常对照组、良性肿瘤、恶性肿瘤，ＳＦ均值分别为２９．５μｇ／Ｌ、１０３．２μｇ／Ｌ、１３５．５μｇ／Ｌ．良、恶性肿瘤相比较，Ｐ＞０．０５，两者与对照组相比较，Ｐ＜０．０１．进一步分析良、恶性肿瘤手术前后的ＳＦ，发现术后的ＳＦ值均高于术前．
From January 1994 to June 1994, 26 benign and 63 malignant tumors were randomly selected from 621 hospitalized patients by double-blind method for the determination of serum ferritin (SF), SF of 73 healthy blood donors Control group. The results showed that the average value of SF in normal control group, benign tumor and malignant tumor was 29.5μg / L, 103.2μg / L and 135.5μg / L, respectively. Compared with benign and malignant tumors, P> 0.05, both compared with the control group, P <0.01. Further analysis of benign and malignant tumors before and after the operation of SF, found that postoperative SF values were higher than preoperative.
