铁蛋白是人体内主要的含铁蛋白,在哺乳动物肝、脾、骨髓中含量最丰富,血中仅有微量存在。自1972年Acldison等应用血清放射免疫测定法以来,对铁蛋白的研究发展很快。近几年来观察资料证实恶性肿瘤病人的血清铁蛋白含量增高,并已应用于恶性肿瘤病人的诊断基于上述报导我们拟定了血清铁蛋白在肺癌诊断上的应用观察。本文以105例肺癌的血清铁蛋白值与X线表现,病理类型及转移情况为观察基础,探讨血清铁蛋白值与X线检查在肺癌诊断中的印证 Ferritin is the main iron-containing protein in the human body. It contains the most abundant liver, spleen, and bone marrow in mammals, and only trace traces of blood exist. Since the application of serum radioimmunoassay by Acldison et al. in 1972, the research on ferritin has developed rapidly. Observations in recent years have confirmed the increase in serum ferritin levels in patients with malignant tumors and have been applied to the diagnosis of patients with malignant tumors. Based on the above reports, we have developed observations on the application of serum ferritin in the diagnosis of lung cancer. This article is based on the observation of serum ferritin and X-ray findings, pathological types and metastasis of 105 lung cancer patients, and explores the relationship between serum ferritin and X-ray examination in the diagnosis of lung cancer.
