To evaluate the short-term safety and efficacy of the new generation of 70-150 ┬Ám drug-eluting beads (M1 DEB) in patients with hepatocellular carcinoma undergoing transarterial chemoembolization (TACE) as a primary therapy or as a bridge to liver transplantation (LT).


Forty-five consecutive patients underwent TACE with M1 DEB loaded with doxorubicin (DEBDOX/M1). Clinical data were recorded at 12, 24, and 48 h, 7 and 30 days after treatment. Response was assessed by computed tomographic scan according to the modified response evaluation criteria in solid tumors criteria, and a second DEBDOX/M1 TACE was scheduled within 6 weeks in case of a noncomplete response.


All patients had well-compensated cirrhosis (97.7 % Child A, 44.4 % hepatitis C virus, median age 61 years). Twenty patients (44.4 %) had Barcelona Clinic for Liver Cancer class B disease; the median number of nodules and their sum of diameters were 2 (range 1-6) and 43 mm (range 10-190), respectively. The mean number of TACE procedures per patient was 1.4. Objective response rate (complete + partial response) was 77.7 % with a median time to best response of 3 months (95 % confidence interval 2-4). In 13 patients, DEBDOX/M1 TACE served as a bridge/downstaging to LT/surgery. Pathology showed that more than 90 % necrosis was achieved in 10 of 28 nodules. DEBDOX/M1 TACE was well tolerated, and the grade 3/4 adverse event rate was low (1 of 65 procedures).


DEBDOX/M1 TACE is an effective procedure with a favorable safety profile and promising results in terms of objective response rate, tumor downstaging, and necrosis.
