Liver transplantation for hepatocellular carcinoma (HCC) is the treatment of choice for patients with unresectable tumors within the Milan criteria associated with Child B or C cirrhosis. Liver transplantation provides the best cure for both the HCC and the underlying cirrhosis. In recent years, some authors have advocated liver transplantation even for resectable early HCC associated with Child A cirrhosis, leading to a controversy of whether resection or transplantation should be the first-line therapy for patients with small HCC in Child A cirrhosis. Recent studies comparing liver resection and transplantation for early HCC demonstrated similar long-term survival of 60-70%, but liver transplantation is associated with a lower tumor recurrence rate. However, the current shortage of deceased donor liver grafts limits the applicability of liver transplantation for HCC. The use of live donor liver transplantation for patients with a small solitary HCC in Child A cirrhosis that is resectable may not be justified ethically because of the potential risk to the donors. Patients put on a transplantation waiting list run a significant risk of tumor progression and dropout, while liver resection is immediately applicable to all. Advocating primary liver transplantation for patients with early HCC associated with compensated cirrhosis will increase the waiting time for transplantation and further increases the chance of dropout. Resection first and salvage transplantation for recurrent tumors or liver failure is an alternative strategy that may reduce the use of liver grafts. However, the long-term survival result of such a strategy compared with primary liver transplantation remains unclear.
肝细胞癌(HCC)肝移植是米兰标准内不可切除肿瘤且伴有Child B或C级肝硬化患者的首选治疗方法。肝移植为HCC和潜在的肝硬化提供了最佳的治愈方案。近年来,一些作者主张即使对于伴有Child A级肝硬化的可切除早期HCC患者也进行肝移植,这引发了对于Child A级肝硬化小HCC患者一线治疗应选择切除还是移植的争议。最近比较早期HCC肝切除和肝移植的研究表明,两者长期生存率相似,均为60 - 70%,但肝移植的肿瘤复发率较低。然而,目前尸体供肝的短缺限制了肝移植在HCC治疗中的应用。对于Child A级肝硬化且可切除的小孤立性HCC患者使用活体供肝肝移植,由于对供体存在潜在风险,在伦理上可能不合理。列入移植等待名单的患者有肿瘤进展和退出等待的重大风险,而肝切除对所有患者均可立即实施。主张对伴有代偿性肝硬化的早期HCC患者进行原位肝移植会增加移植等待时间,并进一步增加退出等待的几率。先切除肿瘤,对于复发肿瘤或肝衰竭进行挽救性移植是一种替代策略,可能会减少肝移植的使用。然而,与原位肝移植相比,这种策略的长期生存结果仍不明确。
