Miriplatin (MPT) is a novel platinum complex used in TACE that shows promise for the treatment of hepatocellular carcinoma (HCC). However, rapid washout has been reported in some cases. Therefore, various methods of administration with MPT have been attempted to increase its therapeutic efficacy. One hopeful method is balloon-occluded TACE (B-TACE), but the therapeutic efficacy of B-TACE with MPT has not been evaluated.To investigate the treatment outcomes and factors involved in local recurrence after B-TACE with MPT in HCC.This study included 51 patients (55 nodules) with HCC lesions equal or less than 5 cm in diameter who underwent B-TACE with MPT between January 2012 and June 2013. Local recurrence after B-TACE with MPT and factors associated with local recurrence were evaluated.The overall local recurrence rate was 11.1% at 6 months and 26.2% at 12 months. The local recurrence rate did differ significantly depending on CT values immediately after B-TACE with MPT. Multivariate analysis also showed that the CT value after B-TACE with MPT was the only factor related to local recurrence after B-TACE.B-TACE with MPT achieves relatively good local control of HCC. The plain CT value immediately after B-TACE with MPT is a predictive factor for local recurrence. In patients with unsatisfactory CT values, locoregional therapy or additional treatment is required.
