Role of transarterial chemoembolization before liver resection for hepatocarcinoma.
The aim of this study was to clarify whether chemoembolization (TACE) before liver resection (LR) can reduce postoperative hepatocellular carcinoma (HCC) recurrence and improve disease-free and overall survival. Eighty-nine patients with tumor-stage (TNM) I-II HCC were evaluated for LR. Patients were prospectively allocated to LR alone or TACE plus LR based on their place of residence. Twenty nonlocal patients (24%) were selected for LR, while 69 (77.5%) local patients were selected for TACE plus LR. Following TACE, the tumor stage could be confirmed in only 20 patients (29%) who then underwent LR. Operative mortality was 0%, but in the TACE-LR group, 3 patients died of liver failure between 2 and 5 months after surgery. Early recurrence (<24 months) was 59% for LR versus 20% for TACE plus LR (P <.05). Late recurrence was 18% for LR versus 10% for TACE plus LR (P = not significant [NS]). The overall recurrence rate was 76% for LR versus 30% for TACE plus LR (P <.02). Death due to HCC recurrence was 70% for LR versus 15% for TACE plus LR (P <.05). The overall 1- and 5-year survival rates did not differ significantly (71% to 38% for LR v 85% to 43% for TACE + LR; P = NS), whereas the difference in 1- and 5-year disease-free survival was highly significant (64% to 21% for LR v 82% to 57% for TACE + LR; P <.02). TACE was able to improve the HCC staging process and significantly reduce the incidence of early and overall HCC recurrence and related death after LR; it improved the disease-free interval, but not the overall survival, due to an increase in liver failure in the first 5 months.
