Objective: We aimed to evaluate local tumor control after transarterial chemoembolization (TACE) for hepatocellular carcinoma using miriplatin and low-dose epirubicin combination therapy.
Methods: We retrospectively analyzed the records of patients who underwent TACE using miriplatin plus low-dose epirubicin (30 patients, 61 nodules, August 2011–March 2012) and control patients who underwent TACE using miriplatin alone (36 patients, 70 nodules, June 2010–July 2011). The local control rate was compared between the two groups using the Kaplan–Meier estimator and the log-rank test. Factors affecting local tumor recurrence were analyzed using multivariate logistic regression analysis. Treatment-related toxicity was evaluated using the Common Terminology Criteria for Adverse Events.
Results: The local control rates at 6 months and 1 year were 87% and 65% for the miriplatin plus low-dose epirubicin group, and 61% and 43% for the miriplatin group, respectively. Local tumor control rates were significantly better in the miriplatin plus low-dose epirubicin group than in the miriplatin group (P = 0.038). Multivariate analysis showed that the addition of epirubicin was an independent factor associated with better local tumor control (hazard ratio 0.2, P = 0.001). Overall incidence rates for adverse events were not significantly different between the two groups.
Conclusion: Additional usage of low-dose epirubicin for TACE using miriplatin improved local tumor control of hepatocellular carcinoma with adverse effects comparable to those observed with TACE using miriplatin alone.
