Recurrent hepatocellular carcinoma successfully treated with radiofrequency thermal ablation.
We report a patient with hepatocellular carcinoma (HCC) who was successfully treated with radiofrequency thermal ablation (RFA). A 71-year-old man was admitted to our hospital in August 1996 with recurrence of HCC. Partial hepatic resection had been performed in January 1993 for HCC that had measured 1.3 cm in segment VIII, and subsequently he had received six sessions of percutaneous ethanol injection (PEI) for treatment of recurrence. Dynamic computed tomography (CT) performed in August 1996 showed two recurrent tumors, one measuring 3.8 cm in segment VIII adjacent to the right hepatic vein, and one measuring 2.0 cm in segment V. Three sessions of percutaneous RFA were performed. After this treatment, most of the tumor in segment VIII and all the tumor in segment V showed low density on dynamic CT, and the right hepatic vein was preserved. However, a remnant of the mass appeared near the right hepatic vein 2 months after the treatment. An additional two sessions of RFA were performed. After the end of treatment, serum alpha-fetoprotein level dropped to the normal range, and no sign of recurrence has been observed until September 1998.
