Abstract
Objective
The aim of this prospective study was to evaluate the efficacy of transarterial chemoembolization using miriplatin, a platinum-based anticancer drug, as a retreatment regimen for hepatocellular carcinoma (HCC) unresponsive to chemoembolization using epirubicin. Methods
Between April 2013 and December 2014, we enrolled 57 consecutive chamoembolization-naïve patients with unresectable HCC, and performed chemoembolization with epirubicin. Treatment effect, necrotizing rate of the target nodules, was evaluated at 1–3 months after treatment using contrast-enhanced CT or MRI. We subsequently included retreatment chemoembolization with miriplatin for patients whose treatment effect was <50% after chemoembolization with epirubicin. The treatment effect after chemoembolization with miriplatin and the liver function before and after chemoembolization were evaluated. Results
Eighteen patients of the 57 showed a treatment effect <50% after chemoembolization with epirubicin, and were switched to chemoembolization with miriplatin. The treatment effect after chemoembolization with miriplatin was ≥50% in four (22%) patients. Four of the remaining 14 (78%) patients who had <50% necrosis exhibited deterioration of the liver function after chemoembolization with miriplatin. Univariate analysis indicated that an alpha-fetprotein-L3 level <10% and a serum albumin level ≥3.6 g/dl were predictive factors of therapeutic response after chemoembolization with miriplatin (P < 0.05). However, there was no predictive factor regarding the deterioration of liver function after chemoembolization with miriplatin. Conclusions
In unresectable HCC patients who were unresponsive to chemoembolization with epirubicin, switching the chemotherapeutic regimen to a platinum-based anticancer drug in retreatment chemoembolization should be considered as a treatment option. Trial registration: UMIN 000015887http://ift.tt/2yPzkuu
