本文报导五例肝细胞患癌者,在肿瘤尚小时已作出确诊。其中一例 AFP 始终是阴性。二例血清甲胎蛋白(AFP)突然上升,故能早期发现肿瘤并作外科手术切除。作者分析了这些病例 AFP 水平出现急剧上升的可能原因,认为或者是由于肿瘤生长速度突然加快,或者是产生 AFP 的细胞系成为主要生长力量,也可能是由于 AFP 的增加打破了 AFP 产生与分 This article reports five patients with hepatocellular carcinoma who have been diagnosed with the tumor still in the air. One of the AFPs was always negative. Two cases of serum alpha-fetoprotein (AFP) suddenly rose, so that early detection of the tumor and surgical resection. The authors analyzed the possible causes of the sharp rise in AFP levels in these cases. They believe that either the tumor growth rate suddenly increased or that the AFP-producing cell line has become a major growth force, or it may be due to the increase in AFP that breaks AFP production and scores.
