BACKGROUND/AIMS: Recent advances in both the diagnosis and treatment of hepatocellular carcinoma (HCC) have improved its prognosis. Intrahepatic recurrence after hepatectomy can be treated with repeated hepatectomy, transhepatic arterial embolization (TAE), percutaneous ethanol injection therapy (PEIT), or microwave coagulo-necrotic therapy. However, treatment for extrahepatic recurrence is also important in prolonging survival in some patients. METHODOLOGY: After radical hepatectomy in 155 patients, extrahepatic recurrences were found in 15 patients that underwent subsequent treatment. The interval between completing treatment for the primary tumor and the discovery of metastasis, the location and mode of treatment of the metastasis, and the outcomes were analyzed. RESULTS: Distant metastasis was detected at a mean of 7 months after radical resection of the primary tumor. Location of the metastasis included lung, bone, and adrenal gland. Four patients had no intrahepatic recurrence and 11 patients had simultaneous intrahepatic recurrence. Six patients with intrahepatic and extrahepatic recurrence that underwent systemic chemotherapy had poor prognoses, and all died within 12 months as a result of progression of the intrahepatic tumor. Five patients with intra- and extrahepatic recurrence that underwent systemic chemotherapy combined with hepatic arterial infusion chemotherapy had relatively good outcomes; all survived for more than 12 months. CONCLUSIONS: These results suggest that to obtain a good prognosis for extrahepatic metastasis coexisting with intrahepatic recurrence, intrahepatic recurrence should be controlled by locoregional therapy, and extrahepatic metastasis should be controlled by systemic chemotherapy and/or irradiation therapy.
