Long-Term Survival of Two Patients with Liver Metastases from Advanced Gastric Cancer Treated with Radiofrequency Ablation and Chemotherapy

Abstract

Liver metastasis from gastric cancer has a very poor prognosis. Herein, we present two cases of liver metastases (synchronous and metachronous) from advanced gastric cancer. In the first case, the patient underwent radical subtotal gastrectomy. Liver metastases occurred 6 months after surgery while the patient was receiving adjuvant chemotherapy, but two hepatic tumors were successfully removed by radiofrequency ablation (RFA). In the second case, liver metastases occurred 15 months after surgery for gastric cancer. The patient also received RFA for one hepatic tumor, and other suspicious metastatic tumors were treated with systemic chemotherapy. Although these case presentations are limited for the efficacy of RFA treatment with systemic chemotherapy for hepatic metastases from gastric cancer, our findings showed long-term survival (overall survival for 108 and 67 months, respectively) of the affected patients, without recurrence. Therefore, we suggest that RFA treatment with systemic chemotherapy could be an effective alternative treatment modality for hepatic metastases from gastric cancer.
