不能手术切除的大肝癌目前临床上尚无有效的治疗办法。作者自1992年6月至1996年6月，对不能手术切除的大肝癌行肝动脉插管化疗栓塞二步切除17例，取得明显疗效，3年生存率明显提高。尽管观察时间尚短，例数不多，但证明了无根治希望的肝癌可以转变为有根治希望的肝癌，因而不论在理论上还是在实践上都具有重要意义。
There is no effective treatment for large liver cancer that cannot be surgically removed. From June 1992 to June 1996, the authors obtained 17 cases of hepatic arterial chemoembolization and two-step hepatic arterial embolization for large unresectable hepatocellular carcinoma. The 3-year survival rate was significantly improved. Although the observation time is short and the number of cases is small, it is proved that hepatoma with no hope of radical cure can be transformed into hepatocellular carcinoma with hope of cure. Therefore, it is of great significance both in theory and in practice.
