肝细胞癌生物行为学特性与肿瘤微血管特征的关系研究

To discuss the relationship of the biological features of Primary hepatocellular carcinoma (HCC) and the characteristics of tumor microvessel.Collecting 52 carcinoma tissues resected surgically and observing the tumor size, differentiation degrees of the tumor, the cancer embolus of portal vein, the satellitic nubble of the tumor, the microvessels width of the tumor, trabecular diameter grade of the tumor and the tumor microvessel density (MVD) by Light microscopical study and immunohistochemistrial examination.The outcomes were statistically count. (1) With the increasing of the diameter of microvessel and width of tumor trabecular, the size of tumor has the tendency of increasing. (2) The MVD of the HCC having satellitic nubble and having lower differentiation degrees were higher, and the microvessels width of tumor were bigger. (3) The MVD of the HCC having cancer embolus of portal vein were higher.This shows: (1) The MVD of HCC were not even distributed in HCC. (2) The Characteristics of tumor microvessel in HCC in different vegetal phases and in different degrees were distinctive, and there were definite rule. (3) The causality between biological features of HCC and the characteristics of tumor microvessel will be further stdied.
