关于小肝癌的新概念,直径≤3cm瘤结节不超过2个,切除后2个月内AFP转为阴性者。本文符合这一概念的小肝癌共35例。术后1、3、5年生存率分别为100％、71.9％和67.9％。切除术后AFP仍然阳性者,为“假性”小肝癌。当切除范围足够时,局部切除也可达到根治目的。在AFP≤1,000ng/ml时手术,可提高术后生存率。肿瘤有无包膜及血管内有无瘤栓,是影响预后的主要病理因素。
With regard to the new concept of small hepatocellular carcinoma, no more than 2 tumor nodules with a diameter of ≤ 3cm, and AFP turned negative within 2 months after resection. This article is consistent with this concept of a total of 35 cases of small hepatocellular carcinoma. The 1-, 3-, and 5-year survival rates were 100%, 71.9%, and 67.9%, respectively. After the resection, AFP was still positive and it was a “pseudo” small liver cancer. When the extent of resection is sufficient, local resection can also achieve the purpose of radical cure. Surgery at AFP ≤1,000 ng/ml improves postoperative survival. Whether or not the tumor has a capsule and whether there is a tumor thrombus in the blood vessel is the main pathological factor that affects the prognosis.
