彩色多普勒血流显像能预示肝癌的恶性程度吗?

Can the Degree of Malignancy of Hepatocellular Carcinoma Be Indicated by CDFI?

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。

The relation between CDFI, DNA content and pathologic staging of 32 specimens obtained by liver biopsy or operatoin were studied. The results showed that 69.0% of small HCC and 87.6% of large HCC had heteroploid DNA content. The difference of the rate of heteroploid between the large HCC and small HCC was statistically significant. However, no correlation was found between DNA content, pathologic staging and Vmax RI of the arterial blood flow. It is confirmed biologically that the HCC is defined as small when its diameter is ≤3 cm and no correlation was found between the arterial blood flows inside or outside the tumor Vmax, RI and the degree of malignancy.
