原发性肝癌的动脉供血特点

目的　探讨供血动脉分型与肝癌的生物学特性的关系及其对临床治疗选择的意义。　方法　分析和统计了419例巨块型原发性肝癌(>10cm)患者的动脉造影资料及临床资料。　结果　根据供血动脉数量的多少及形态,把原发性肝癌的供血动脉分为中央型、外周型、混合型和少供血型四种。前三型为多供血型,占7184%,少供血型占2816%。中央型根据血管的分支形态分为穿透型、树枝型、团状型三种亚型,分别占中央型的4063%、5260%、677%。外周型根据供血动脉的数量分为单枝型和多枝型两种亚型,分别占外周型的3043%和6957%。外周型肝癌患者的1年和2年生存率较中央型和混合型高,而少供血型肝癌较多供血型低。　结论　肝癌的供血动脉分型对肿瘤生物学特性的了解、临床治疗的选择及预后的判断具有重要的意义

CHARACTERISTICS OF ARTERIAL SUPPLY IN PRIMARY LIVER CANCER

PURPOSE To study the relationship between the types of arterial supply in primary liver cancer (PLC) and its biologic features as well as its clinical therapeutic implication.METHODS The arterial hepatic angiography and the clinic data were analysed and summed up in 419 cases with huge primary live cancer(PLC>10 cm).RESULTS According to the number and shape of supply artery,the supply artery of PLC was divided into four types:central, peripheral,mixed and minimal blood supply types.The first three types were abundant blood supply types taking up 71.84%.The last type made up 28.16%.The central type was divided into three subtypes:penetrating,branching and spherical which accounted for 40.63%,50.60% and 6.77% respectively according to the shape of supply arterial branch and the peripheral type had two subtypes:singel branch and multibranch which constituted 30.43% and 69.57% respectively according to the number of supply arterial branches.One year and two year survival rate in the periphery type were higher than the center type and the mix type. The minimal blood supply type lower then the abundant blood supply type.CONCLUSIONS the arterial supply types of PLC were of great significance for learning the biologic features,selecting the clinical therapies and judging the prognosis.
