转移性肝癌边缘回声与其生长关系的研究

An Ultrasonography Study of the Relationships between Boundary Echo and Growth in Liver Metastasis

应用彩色多普血流显像和超声引导下穿刺活检，观察了转移性肝癌边缘回声与其生长关系（大小变化、形态改变、生长方式和快慢）。结果发现边缘回声与其病理改变有关，与原发部位无关。转移性癌生长快慢与肿瘤周边有无结维包膜及免疫炎性细胞多少、血供有关，周边纤维结缔组织包膜的存在对转移性肝癌的生长起限制作用，边界不清，呈浸润性生长，血供丰富，生长迅速，由园形变为不规则形。同时还发现部分低回声晕是由血管组成，边缘回声反映了肿瘤病理和生长的特性，为防止炜移性肝癌形成和生长提供依据，对指导转移癌的治疗、判断疗效、估计预后具有重要意义。

Boundary echo and growth in liver metastasis were studied with ultrasonogaphy and biopsy.The results show that boundary echo changes determine the growth in liver metastasis,which is related to the presence or absence of fiber connection tissue membrane,the amount of inflamation cells,and blood supply,The fiber connection tissue membrane in tumor boundary contrals the tumor growth,Boundary echo manifests the characteristics of the growth and pathology of the tumor,which may throw light on the prevention of liver metastasis from forming and growing.
