[Laparoscopic Resection of Solitary Lymph Node Metastasis of Hepatocellular Carcinoma after Transcatheter Arterial Chemoembolization and Percutaneous Locoregional Therapies].

A 75-year-old woman underwent transcatheter chemoembolization(TACE)for 2 small hepatocellular carcinoma(HCC) lesions associated with severe alcoholic liver cirrhosis that necessitated management for ascites. Over 5 years after the initial TACE, she received multidisciplinary therapies with TACE, transcatheter arterial infusion of anticancer agents, percutaneous ethanol injections, or percutaneous radiofrequency ablation performed on 5 occasions for small recurrent HCC lesions. Computed tomography performed after the last therapy for HCC revealed a solitary lymph node swelling(39 mm in diameter) around the common hepatic artery. Magnetic resonance imaging performed 3 months later revealed that the lymph node had enlarged to 45 mm, without recurrence of the primary HCC, and after 4 months, to 60 mm; she then underwent laparoscopic lymph node resection. Histopathological examination of the resected specimen showed HCC metastasis. A recurrent metastatic lymph node(30 mm in diameter)was detected around the common hepatic artery and was resected laparoscopically 17 months postoperatively. Pancreatic head cancer was diagnosed 22 months after the second surgery; however, the patient refused cancer therapy and died 16 months after this diagnosis. No recurrence of the primary HCC or lymph node metastasis was observed over the 38 months after the second surgery.
