RESUMEN
BACKGROUND AND AIMS: Conventional transcatheter arterial chemoembolization (C-TACE) and drug-eluting bead (DEB)-based TACE are current treatments for hepatocellular carcinoma (HCC). We compared the therapeutic efficacies and adverse events of these methods in a single-center retrospective cohort study. METHODS: We enrolled 174 patients treated between January 2010 and October 2016; 98 and 76 underwent C-TACE and DEB-TACE, respectively, with 76 and 22 of the former group and 49 and 27 of the latter group classified as Child-Pugh class A and B, respectively. Therapeutic outcomes, progression-free survival (PFS), and adverse events were evaluated. RESULTS: The PFS rates in the C-TACE and DEB-TACE groups were 8.1 and 6.1 months, respectively (p = 0.79). The response and disease control rates were 64 and 71% in C-TACE patients and 69 and 78% in DEB-TACE patients, respectively (p = 0.25). Postprocedural pain, vomiting, and fever were more frequent following C-TACE than DEB-TACE (p < 0.001). In contrast, the incidences of bilomas and arterio-portal shunts were significantly higher following DEB-TACE (p < 0.001); the incident rates of arterio-portal shunt formation were 8.1 and 48.7% in patients undergoing C-TACE and DEB-TACE, respectively. Child-Pugh class A was significantly associated with arterio-portal shunt formation after DEB-TACE on multivariate analysis. CONCLUSIONS: There were no significant differences in the therapeutic efficacies of C-TACE and DEB-TACE. However, the frequency of arterio-portal shunt formation was significantly higher in HCC patients with Child-Pugh class A undergoing DEB-TACE. Our findings imply that C-TACE should be selected for HCC patients with Child-Pugh class A and DEB-TACE should be chosen for those with Child-Pugh class B.

AIM: Prognosis of hepatocellular carcinoma (HCC) with macrovascular invasion (MVI) is extremely poor. However, proper therapeutic strategies have not been established yet. The purpose of this study is to identify the effects of external beam radiation therapy (EBRT) for MVI of HCC. METHODS: We have analyzed and evaluated 80 consecutive patients with HCC with MVI who underwent EBRT, and factors associated with enhanced survival in EBRT were evaluated by univariate and multivariate analysis. RESULTS: The local response rate of radiotherapy for the irradiated MVI was 66.2%. The time to progression of the irradiated MVI was 5.8 months. Univariate and multivariate analyses showed that the higher irradiation dose (over 45 Gy) and the irradiation location (hepatic vein tumor thrombus - HVTT) were significant factors associated with survival benefits of EBRT. The response of EBRT for HVTT was significantly superior to that for portal vein or bile duct tumor thrombus. CONCLUSION: We conclude that a multidisciplinary therapeutic strategy based on EBRT should be proactively selected in the treatment of advanced HCC with MVI.
