Influence of treatment of hepatocellular carcinoma before liver transplantation on post transplant tumor recurrence and survival
Abstract
To evaluate the effectiveness of treatment of hepatocellular carcinoma (HCC) before liver transplantation (LT) and its influence on survival and tumor recurrence in patients transplanted for HCC. We included 67 liver transplant patients with a preoperative diagnosis of HCC and pathological confirmation in the native liver between January 2000 and October 2007. Treatment before LT was performed in 46 (68.7%) patients [radiofrequency ablation in 18, transarterial chemoembolization in 31 and percutaneous ethanol injection in two]. The median time between inclusion on the waiting list and LT was 4 months and was similar in treated and untreated patients. The median time between pre-transplantation locoregional therapy and LT was less than 6 months in 65.2% of the patients. Treated patients had better liver function (Child A 52.2 vs 19%; Child B 39.1 vs 33.3%; Child C 8.7 vs. 47.6%; p=0.001) and a higher proportion of total tumor size > 3 cm (59.1% vs 30%; p=0.031). Total tumor necrosis was observed in 26.1% of the patients, with no differences according to treatment modality or tumor size. Tumor recurrence occurred in six patients (9%). The median time between LT and tumor recurrence was 26.5 months with a subsequent median surviva...Continue Reading
