Background: Transarterial chemoembolization (TACE) is recommended as a treatment for unresectable hepatocellular carcinoma (HCC) in patients with normal underlying liver function. The efficacy of TACE in cirrhotic patients with compromised liver function is unknown., Methods: All ‘first’ TACE interventions for HCC performed at a single institution from 2008 to 2012 were retrospectively reviewed (n = 190). Liver function was quantified via the Child's score. Tumour necrosis after TACE was quantified via the mRECIST criteria., Results: The 'first' TACE procedures of 100 Child's A and 90 Child's B/C cirrhotic patients were evaluated. As expected, the lab-model for end-stage liver disease (MELD) score was significantly higher in the Child's B/C group. Although the number of tumours were similar between the groups, both the size of the largest tumour and the total tumour diameter were greater in the Child's A group. There were no significant differences in post-TACE tumour necrosis between groups. The median survival after TACE was significantly longer in the Child's A compared with Child's B/C patients (21.9 versus 13.7 months, P = 0.03)., Conclusions: TACE appears to be equally efficacious in cirrhotic patients regardless of their Child's classification based upon equivalent mRECIST measures of tumour necrosis. However, inferior survival after TACE was observed in the Child's B/C group., (© 2013 International Hepato-Pancreato-Biliary Association.)

Background: Radiographical features associated with a favourable response to trans-arterial chemoembolization (TACE) are poorly defined for patients with hepatocellular carcinoma (HCC)., Methods: From 2008 to 2012, all first TACE interventions for HCC performed at the University of Alabama at Birmingham (UAB) were retrospectively reviewed. Only patients with a pre-TACE and a post-TACE computed tomography (CT) scan were included in the analyses (n = 115). HCC tumour response to TACE was quantified via the the modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria. Univariate and multivariable analyses were constructed., Results: The index HCC tumours experienced a > 90% or complete tumour necrosis in 59/115 (51%) of patients after the first TACE intervention. On univariate analysis, smaller tumour size, peripheral tumour location and arterial enhancement were associated with a > 90% or complete tumour necrosis, whereas, only smaller tumour size [odds ratio (OR) 0.62; 95% confidence interval (CI) 0.48, 0.81] and peripheral location (OR 6.91; 95% CI 1.75, 27.29) were significant on multivariable analysis. There was a trend towards improved survival in the patients that experienced a > 90% or complete tumour necrosis (P = 0.08)., Conclusions: Peripherally located smaller HCC tumours are most likely to experience a > 90% or complete tumour necrosis after TACE. Surprisingly, arterial-phase enhancement and portal venous-phase washout were not significantly predictive of TACE-induced tumour necrosis. The TACE response was not statistically associated with improved survival., (© 2013 International Hepato-Pancreato-Biliary Association.)
