再次肝移植治疗首次肝移植术后肝癌肝内复发的效果分析
Clinical analysis of liver retransplantation for intrahepatic recurrence of HCC after liver transplantation
目的 探讨肝癌肝移植术后复发肝癌的病理特点及再次肝移植治疗的意义及其预后.方法 回顾性分析肝移植术后21例肝癌复发患者的临床资料,其中9例接受再次肝移植治疗,12例行姑息治疗.所有患者原发病均为乙型肝炎后肝硬化合并肝癌,肝移植术后肿瘤均为肝内复发,无法局部切除.结果 9例患者首次和再次肝移植时肿瘤病理分析,肿瘤均为肝细胞肝癌,最大肿瘤直径分别平均为6.2 cm和4.8 cm,多发肿瘤者分别占67%和89%,有微血管侵犯者分别占100%和56%,肿瘤分化为Ⅱ级、Ⅲ级和Ⅳ级者分别为33%、67%、0和22%、22%、56%,复发肝脏肿瘤的平均最大直径和分化程度与原发肝脏肿瘤比较,差异均有统计学意义(P<0.01).首次肝移植术后再次移植组患者无瘤存活时间中位数为15.0个月,再次肝移植术后无瘤存活时间中位数为2.5个月,再次移植术后存活时间中位数为5.8个月,总体存活时间中位数为21.8个月;姑息治疗组受者肝移植术后无瘤存活时间中位数为13.0个月,总体存活时间中位数为17.6个月;再次移植组和姑息治疗组术后1、2、3年累积存活率分别为89%、44%、33%和91%、45%、9%,两组间存活率比较,差异无统计学意义(P>0.05).结论 血管侵犯为肝癌复发的高危因素;复发肿瘤分化程度更低;首次肝移植术后肝癌肝内复发可能是术前和术中肿瘤全身播散的早期临床特点和局部表现,不建议再次肝移植治疗肝癌肝移植术后肝癌肝内复发.
更多Objective To investigate the clinicopathological characteristics of retransplantation for intrahepatic recurrence of hepatocellular carcinoma (HCC) after liver transplantation (LT).Methods In a center hospital of organ transplantation setting,9 patients after primary liver transplantation had intrahepatic recurrence and received retransplantation,and 12 patients in control group were not subjected to LT over the same period.The follow-up period was 10 to 58 months.Results As compared the pathological characteristics of secondary transplanted liver with primary thansplanted liver,there was significant difference in tumor differentiation (grade Ⅱ,Ⅲ and Ⅳ)between primary group (33%,67% and 0) and secondary group (22%,22% and 56%) (P<0.01).After primary liver transplantation,median of tumor free survival was 15.0 months.After secondary liver transplantation,median of survival was 5.8 months,and median of tumor free survival was 2.5 months.In control group,median of tumor free survival was 13.0 months,and total survival survival was 17.6 months.In transplantation group and control group,1-,2-,and 3-year cumulative survival rate was 89%,44%,33% and 91%,45%,9% respectively,with the difference being not statistically significant (P > 0.05).Conclusion It is high risk of vascular invasion for tumor recurrence.The differentiation grade of recurrent tumor is lower.The sign of intrahepatic recurrence of HCC after liver transplantation may be early and local clinical characteristics of tumor cell disseminating and metastasis before and during operation,and it is not recommended to perform retransplantation.
