[A case of metachronous liver metastasis from gastric cancer treated with multidisciplinary therapy including hepatectomy].

A 73-year-old man underwent a distal gastrectomy with dissection of D2 lymph nodes for type 2 gastric cancer at the front wall of pyloric antrum in June 2006 (Pathological finding was moderately differentiated adenocarcinoma, T2, N0, H0, P0, M0, fStage IB). Although he was given UFT and PSK for postoperative adjuvant therapy, MRI showed a liver metastasis at segment 6 of the liver in June 2007. After 2 courses of S-1, posterior segmentectomy of the liver was performed. After hepatectomy, 5 courses of S-1 as adjuvant therapy were administered. However, another metachronous liver metastasis appeared at segment 8 in August 2008. After 3 courses of S-1 and CDDP, we performed radiofrequency ablation (RFA) therapy and a good cauterization effect was obtained. There has been no recurrence for 3 years since gastrectomy, or 2 years since the first liver metastasis. We experienced a case of metachronous liver metastasis from gastric cancer treated with multidisciplinary therapy that was beneficial for a long term survival.
