From January 1970 to January 1987, hepatic hilar liver cancer (or central type of hepatic cancer) resection was done in 51 cases. The resection was often extremely difficult, and sometimes complete occlusion of the hepatic blood supply was needed when the tumor lied close to, or already invaded the great blood vessels. The 1-, 3-, and 5- year postoperative survival rates were 65.7%, 45.3%, and 38.8%, respectively, in contrast to 93.8%, 86.1%, and 80.1% (P less than 0.001) obtained in 51 cases of peripheral type liver cancer of similar tumor size during the same period. It is considered that the difficulty involved in the resection of such a cancer, the limited extent of resection, and the easy entrance of tumor cells into the blood stream may explain the poor prognosis.
1970年1月至1987年1月，对51例肝门部肝癌（即中央型肝癌）进行了切除术。该手术通常极为困难，有时当肿瘤靠近或已侵犯大血管时，需要完全阻断肝脏血液供应。术后1年、3年和5年生存率分别为65.7%、45.3%和38.8%，而同期51例肿瘤大小相似的周围型肝癌患者的术后1年、3年和5年生存率分别为93.8%、86.1%和80.1%（P<0.001）。据认为，此类癌症切除的难度、切除范围有限以及肿瘤细胞易于进入血流可能是预后较差的原因。
