本文对３２例肝穿刺或手术标本的细胞核ＤＮＡ含量、病理分级及其与彩色多普勒血流显像的关系进行分析。结果表明：小肝癌异倍体发生率为６９．０％，大肝癌异倍体发生率为８７．６％，两组间异倍体发生率有显著性差异，但内部及外周动脉血流的有无及其最大流速、阻力指数的高低与异倍体发生率、病理分级无显著相关。本文从生物学角度证实了直径≤３ｃｍ可作为小肝癌的定义标准，并提示肿瘤内、外动脉血流的有无及其最大流速和阻力指数的高低与恶性程度无关
In this paper, the nuclear DNA content, pathological grade, and the relationship with color Doppler flow imaging in 32 cases of liver biopsy or surgical specimens were analyzed. The results showed that the incidence of aneuploidy was 69.0% in small hepatocellular carcinoma and 87.6% in large hepatocellular carcinoma. The incidence of aneuploidy was significantly different between the two groups, but the internal and peripheral arterial blood flow There was no significant correlation between the presence or absence of maximal flow velocity and resistance index and the incidence of aneuploidy and pathological grade. This article confirmed from a biological point of view that the diameter ≤3cm can be used as a standard for the definition of small hepatocellular carcinoma, and suggest that the presence or absence of blood flow in the internal and external arteries of the tumor and its maximum flow velocity and resistance index are not related to the degree of malignancy.
