[A case of hepatocellular carcinoma with advanced gastric cancer treated by radio frequency ablation].

A 69-year-old male patient has been diagnosed hepatitis B a couple of years ago at our hospital. His follow up CT revealed multiple hepatocellular carcinomas (HCCs) in May 2007. Transarterialchemoembolization was selected for treatment. A couple of months later, carcinoma in segment eight was diagnosed viable by CT. Radiofrequency ablation (RFA) therapy was performed for further treatment but was incomplete. On the other hand, gastric cancer was discovered at the same time. Total gastrectomy with regional lymph node dissection and splenectomy were performed. Pathological examination of the dissected lymph nodes revealed not only the metastases of the gastric cancer but also HCC. Recently, RFA treatment is growing in number for HCC. Although lymph node metastases in HCC are seldom seen, our case suggests that RFA may have led to the unexpected metastases to the lymph nodes.
