Autologous formalin-fixed tumor vaccine suppressed re-recurrence of HCV-related hepatocellular carcinoma following 29 unsuccessful treatments with extensive conventional therapy: a case report.

Abstract

Treatment of hepatocellular carcinoma (HCC) with autologous formalin-fixed tumor vaccine after primary resection has been shown to suppress the recurrence of hepatitis B virus-associated HCC, but the effect of this treatment on hepatitis C virus (HCV)-related disease has not yet been clarified. Here, we report a case of a patient with repeat recurrent HCC that was associated with HCV who had endured 29 episodes of HCC recurrence despite a variety of therapy using conventional methods. Finally, treatment with a single course of autologous formalin-fixed tumor vaccine resulted in suppression of potential further re-recurrence of HCC for more than 43 months without any additional treatment.
