【摘要】 用核素９０Ｙ－玻璃微球在超声穿刺引导下，对已失去手术指征的９例肝癌患者进行直接肝癌肿块内包埋介人治疗。其中４例为原发性肝癌，５例为转移性肝癌，取得了较好的疗效。在治疗后的两个月中，通过Ｂ超在形态学和病理切片与涂片在组织细胞学方面进行复查随访。结果表明，无论原发性与转移性的癌性肿块，Ｂ超提示肝癌肿块发生不同程度的密度改变，其中１例低密度区基本消失。病理提示肝癌细胞存在不同程度的坏死，有的呈坏死后残留空隙改变。此方法对肝癌破坏性大，疗效好．对周围器官损伤小，被治疗者痛苦小，为失去手术指征的肝癌患者提供有效的治疗手段。治疗后血常规、肝肾功能、出凝血时间均无明显变化。更多还原

【Abstract】 cases of liver cancer (4 primary and 5 metatic) using 90Y-glass traped microspere injected into the unresected liver masses guided by realtime liver echography were reported. Two months later B ultrasound indicated there was a density change of the tumor mass with various magnitude, among them low density area almost disappeared in one case. The gistologic studies showed some tumor cells becaxne nectotic and leaves a hollow space. No patients complained discomfort or pain during and after treatment. It is not harmful to surrounding tissues. therefore this method may be an effective therapy modality to treat the inoperable liver cancer without obvious side effects.更多还原
