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（＞10m）患者的动脉造影资料及临床资料。结果：根据供血动脉的数量的多少及形态，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71．84％，少供血型占28．历叽。中央型根据血管的分枝形态分为穿透型，树枝型，团状型三种亚型，分别占中央型的40．63％、52．60％、6．77％。外周型根据供血动脉的数量分为单枝型和多技型两种亚型，分别占外周型的30．43％和69．57％。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。
Objective: To explore the relationship between the type of arterial blood supply and the biological characteristics of liver cancer and its significance for clinical treatment options. METHODS: Angiographic data and clinical data of 419 patients with hepatocellular carcinoma (>10m) were analyzed and analyzed. RESULTS: According to the number and shape of the feeding arteries, the feeding arteries of primary liver cancer were divided into four types: central, peripheral, mixed, and less blood supplying. The first three types were multi-supply type, accounting for 71.84%, and less blood supply type 28. Calendar. The central type is divided into three types of penetrating, dendritic, and lumps depending on the branching pattern of the blood vessels, accounting for 40.63%, 52.60%, and 6.77% of the central type, respectively. Peripheral types were divided into single-type and multi-type subtypes according to the number of blood-feeding arteries, accounting for 30.43% and 69.57% of the peripheral type, respectively. The 1-year and 2-year survival rates of patients with peripheral liver cancer were higher than those with central and mixed types, while those with less blood-supply-type liver cancer were more frequent. Conclusion: It is of great significance to understand the biological characteristics of tumor, the choice of clinical treatment and the judgment of prognosis.
