Abstract
OBJECTIVE
To investigate whether balloon-occluded transcatheter arterial chemoembolization (b-TACE) can produce a more dense accumulation of iodized oil in various stages of hepatocellular carcinoma (HCC), from single to uncountable, to overcome inferior local control.
MATERIALS AND METHODS
We studied 27 patients with HCC, including single to uncountable multiple lesions, who underwent b-TACE between August 2013 and April 2015. Dynamic CT was performed at baseline and 1-3 months after b-TACE. The treatment effect (TE) after b-TACE was evaluated using the Response Evaluation Criteria in Cancer of the Liver (RECICL) proposed by the Liver Cancer Study Group of Japan.
RESULTS
In the countable HCC group, contrast-enhanced CT demonstrated RECICL TE4 in 43.8% (14/32), TE3 in 12.5% (4/32), TE2 in 37.5% (12/32), and TE1 in 6.3% (2/32) of patients. For the TACE-naïve cohort, the objective response rate was 52.9%. The objective response rate was 60% for the previously TACE-treated cohort. In the uncountable multiple HCC group, the objective response rate was 0% (0/10), with progressive disease in 90% (9/10) of patients.
CONCLUSION
Our observations suggested that b-TACE did not reduce the efficacy of retreatment for HCC with an insufficient outcome from conventional TACE, but it could not improve the efficacy of treatment for uncountable multiple HCCs.
