门静脉癌栓分型对肝细胞性肝癌治疗方法的选择及患者预后的影响

门静脉癌栓(PvTT)是肝细胞性肝癌(HCC)患者常见的肿瘤晚期征象,预后差.目前,PVTT的分型方法有日本的VP分型和东方肝胆分型(程氏分型),两者在PVTT分型方面有一定的区别.患者的预后与PVTT的类型存在相关性:Ⅰ0型PVTT患者预后最好,而Ⅳ型PVTT患者预后最差;不同类型的PVTT限制了治疗方式的选择,应根据PVTT的类型选择最佳的治疗方案,最大程度地控制肿瘤,使患者受益.

The application of portal vein tumor thrombus classification in selecting therapeutic method for HCC patients and in estimating the prognosis

Portal vein tumor thrombus (PVTT) is a common finding in patients with advanced hepatocellular carcinoma (HCC),and the presence of PVTT usually indicates a poor prognosis.At present,two PVTT classifications are adopted in clinical practice;they are VP classification of Japan and eastern hepatobiliary classification (Cheng's classification).There are some differences in PVTT classification between the above two typing criterion.Certain correlation exists between patient's prognosis and PVTT typing;for example,PVTT of type Ⅰ0 carries the best prognosis,while PVTT of type Ⅳ indicates the worst prognosis.The choice of treatment plan is limited by the type of PVTT for a given patient.Therefore,the optimal therapeutic regimen should be formulated based on the type of PVTT in order to control HCC and to benefit the patient.
