[A Case of Metachronous Multiple Liver Metastases of AFP and PIVKA-II Producing Gastric Cancer, Responding to Transcatheter Arterial Chemoembolization].

: We report a case of a 75-year-old man with a-fetoprotein(AFP)-producing gastric cancer accompanied by multiple large liver metastases. The patient underwent a total gastrectomy for gastric cancer(p-T3N3H0P0M0, fStage ⅢB). The patient then underwent chemotherapy(TS-1 80m g/day)following the radical operation. However, 5 months after the radical operation, he presented with multiple large liver tumors, which were subsequently biopsied. Based on immunohistochemical examination, the liver tumors were negative for AFP protein, but were similar to hepatoid adenocarcinoma, and no fibrosis was observed in the background liver. Therefore, we diagnosed the tumors as liver metastases of AFP producing gastric cancer and metachronous liver metastasis. The patient underwent transcatheter arterial chemoembolization(TACE). TACE decreased the AFP and PIVKA-Ⅱ levels and reduced the multiple huge liver metastases. Due to the increase in AFP and the multiple liver metastases, despite intensive hepatic infusion chemotherapy, he died 5 months after admission.
