Radiofrequency ablation for metachronous hepatic metastases from gastric cancer.
The objective of this study was to evaluate the results of radiofrequency ablation (RFA) for the treatment of metachronous hepatic metastases from gastric adenocarcinoma. Between January 2000 and February 2008, we retrospectively reviewed 7 cases for which RFA was performed for treating metachronous hepatic metastases after resection of the primary gastric adenocarcinoma. The median period between curative gastrectomy and metachronous hepatic metastasis was 14 months (range: 6 to 48 mo). The median survival of the patients was 11.0 months (range: 5.5 to 39.2) after the first detection of hepatic metastases and 10.0 months (range: 5 to 38.2) after the first RFA. Hepatic metastases recurred 3 to 21 months after RFA in all patients. A second RFA was performed for a single recurrent hepatic metastasis in 1 patient and this patient survived more than 3 years without recurrence until the time of this study. In conclusion, the efficacy of RFA alone for metachronous hepatic metastases from gastric adenocarcinoma was disappointing due to multiple intrahepatic recurrences. Combination therapy such as systemic chemotherapy or hepatic arterial infusion chemotherapy adjuvant to RFA would more reasonable for treating hepatic metastases from gastric cancer.
