本文报告78例肺癌、6例肺转移癌及20例良性肺疾患的血清铁蛋白放射免疫测定结果。78例肺癌中53例血清铁蛋白值增高,阳性率71.1%;6例肺转移癌均增高;20例良性肺疾患中6例增高,假阳性率30.0%,经统计学处理两组具显著性差异(p<0.01)。78例肺癌患者中15例同时检测CEA,血清铁蛋白与血清CEA值均增高者4例;铁蛋白值增高而CEA值正常 This article reports the serum ferritin radioimmunoassay results of 78 lung cancers, 6 lung metastases, and 20 benign lung diseases. In 78 cases of lung cancer, the serum ferritin value was increased in 53 cases, the positive rate was 71.1%; 6 cases of metastatic lung cancer were increased; 6 cases of benign lung disease were increased in 6 cases, the false positive rate was 30.0%, statistically significant in both groups. Difference (p<0.01). Twenty-five of the 78 lung cancer patients were tested for CEA at the same time. Serum ferritin and serum CEA levels were elevated in 4 patients. Ferritin values ​​were elevated and CEA values ​​were normal.
