肝癌合并门静脉癌栓的研究

Research in the portal vein tumor thrombosis for hepatocellular carcinoma

门静脉癌栓（PVTT）是影响肝癌患者预后的重要因素。PVTT的形成是一个多因素、多环节的过程。根据门静脉的解剖特征及癌栓的生长规律，将PVTT分为Ⅰ～Ⅳ型。手术治疗、介入治疗、放疗为主的综合治疗模式提高了疗效。

Portal vein tumor thrombus （PVTT） influence the prognosis of hepatocellular carcinoma. The development of PVTT is a multi-factor, multi-part process. According to anatomic features of the portal vein in the liver and tumor thrombus of HCC developing modes, a uniform tumor thrombus types system （ typesⅠ～Ⅳ ）is recommended. Multi-modal therapy based on surgery, interventional therapy and radiotherapy can improve the curative effect enormously.
