Orthotopic liver transplantation (OLT) is increasingly being applied for cure in patients with cirrhosis and concomitant hepatocellular carcinoma (HCC). In recipients with limited tumor burden, OLT achieves reasonable long-term outcome. This study sought to identify clinical and pathologic variables predictive of long-term disease-free survival and the presence of vascular invasion. From 1992 to 2006, 130 patients underwent OLT for cirrhosis and HCC. Malignancy was diagnosed in 107 patients prior to OLT and in 23 patients on pathologic examination of the explant. Nine clinical and pathologic variables were considered including: TNM stage, nodularity, vascular invasion, Milan criteria, incidental lesion, differentiation, tumor size, preOLT transarterial chemoembolization (TACE), and administration of sirolimus-based immunosuppression. The overall incidence of HCC recurrence was 17% with the majority (82%) being stage III. Cumulatively, tumor recurrence-free survival (RFS) is 84, 74, and 67% at 1, 3, and 5 years respectively. Independent predictors of RFS included stage III and poorly differentiated lesions (P<0.05). Furthermore, stage III tumors and those >3.5 cm in size were predictive of vascular invasion. Importantly, preOLT, TACE and postOLT sirolimus had no influence on survival. Pathologic variables including tumor stage and grade have a significant impact on outcome. Importantly, it seems that TACE and sirolimus had no beneficial effect.
原位肝移植(OLT)越来越多地被用于治疗肝硬化合并肝细胞癌(HCC)患者。在肿瘤负荷有限的受者中,OLT可取得合理的长期疗效。本研究旨在确定预测长期无病生存和血管侵犯的临床及病理变量。1992年至2006年,130例患者因肝硬化和HCC接受了OLT。107例患者在OLT术前被诊断为恶性肿瘤,23例患者在移植肝病理检查时被诊断为恶性肿瘤。研究考虑了9个临床和病理变量,包括:TNM分期、结节性、血管侵犯、米兰标准、偶然病变、分化程度、肿瘤大小、OLT术前经动脉化疗栓塞(TACE)以及基于西罗莫司的免疫抑制治疗的应用。HCC复发的总体发生率为17%,其中大多数(82%)为III期。累积来看,1年、3年和5年的无肿瘤复发生存率(RFS)分别为84%、74%和67%。RFS的独立预测因素包括III期和低分化病变(P<0.05)。此外,III期肿瘤和大小>3.5 cm的肿瘤可预测血管侵犯。重要的是,OLT术前TACE和OLT术后西罗莫司对生存无影响。包括肿瘤分期和分级在内的病理变量对预后有显著影响。重要的是,TACE和西罗莫司似乎没有有益作用。
