摘要
肝移植是经过选择的肝癌患者有效的治疗方法之一,但是约有20%的肿瘤复发率限制了肝癌、肝硬化移植术后的长期生存.尽管有些临床指标会强烈提示复发风险和术前肿瘤肝外转移,从而放弃肝移植.事实上,术后肿瘤复发往往是由于术前或术中出现肝外微转移病灶进一步发展的结果.由于器官的紧缺,肿瘤局部治疗以及外科肝部分切除术成为肝移植术前等待期间的桥梁.而且,更积极的外科切除包括切除肝肿瘤以及肝外孤立的转移灶.这些创造性方案是否能改变生存率目前还不清楚,需要长期的随访才能判定其效果.
Liver transplantation is a valid treatment option for select patients with Hepatocellular Carcinoma HCC and end-stage liver disease. However, in approximately 20% of patients, recurrent HCC is the rate-limiting factor for longterm survival. Despite identification of clinical parameters that may stratify patients at high risk and exhaustive preoperative staging, cancer recurrence is likely the result of microscopic extrahepatic disease. With a desperate donor organ shortage, locoregional ablation techniques and resection are being employed in patients on the waiting list to serve as a bridge to OLT. Further more, some have advocated aggressive surgical resection of isolated metastasis in both the liver and extrahepatic viscera. Whether these creative strategies confer a survival advantage is unknown, requiring longterm follow-up to determine their efficacy.
