随着影像学的进展与普查慢性肝疾病计划的建立,便于了小肝细胞癌(HCC)的诊断。然而约90％HCC者有慢性肝疾病,由于肝硬化及肝功能严重损害,故即使发现是早期肿瘤,也常不能行肝切除。近年来有经皮经肝向肿瘤注射酒精的报道。放射治疗较小的HCC亦再重新评价,但局部放疗的结果仍在争论,且抗肿瘤的效应与并发症尚未充分研究。 With the advancement of imaging and the establishment of a general plan for chronic liver disease, the diagnosis of small hepatocellular carcinoma (HCC) is facilitated. However, about 90% of HCC patients have chronic liver disease. Because of liver cirrhosis and severe liver damage, even if they are early stage tumors, they often cannot undergo hepatectomy. In recent years, percutaneous transhepatic injection of alcohol into tumors has been reported. Radiotherapy for smaller HCC has also been re-evaluated, but the results of local radiotherapy are still in dispute, and the anti-tumor effects and complications have not been fully studied.
