Study of the relationship of biological features of primary hepatocellular carcinoma and the characteristics of tumor microvessel

  • 摘要: 探讨肝细胞肝癌(HCC)生物行为学特性与肿瘤微血管特征的关系。收集手术切除的HCC标本52例,进行了肿瘤微血管密度(microvessel density,MVD)记数、微血管直径测量、梁索直径测量、肿瘤直径测量、细胞分化程度分级、癌栓、卫星结节观察。对肿瘤生物行为学特性和微血管特征观察指标进行统计分析。(1)HCC肿块大小与肿瘤MVD相关,与肿瘤微血管直径和肿瘤梁索直径呈正相关趋势;(2)有卫星结节、低分化HCC的MVD较高,肿瘤微血管直径较大;(3)有门脉癌栓的HCC的MVD较高。结论(1)HCC的MVD分布不均匀;(2)HCC在不同生长阶段、不同分化程度,其肿瘤微血管特征是不同的,并有一定的规律;(3)HCC临床生物学特性与肿瘤微血管特征之因果关系有待进一步探讨。
