[A case of multiple liver metastases from nonfunctioning neuroendocrine pancreatic tumor curatively resected after successful intra-arterial chemotherapy].

We report a case of 33-year-old woman for nonfunctioning neuroendocrine pancreatic tumor with synchronous multiple liver metastases. For the primary pancreatic legion, we performed pylorus-preserving pancreatoduodenectomy at first. Three weeks after the surgery, the patient started to undergo intra-arterial chemotherapy with a weekly administration of high-dose 5-FU (1,000 mg/body) for residual liver metastases. Any severe adverse events were not observed. After 20 courses, a partial response was achieved and she underwent curative operation with partial resection for 4 metastatic legions and RFA for others. Histopathological findings of resected specimens revealed no viable neoplastic tissues. She is alive with no sign of recurrence 3 months after the surgery. Although a surgical resection is accepted as the standard therapy for liver metastases of nonfunctioning neuroendocrine pancreatic tumor, intra-arterial chemotherapy might be an alternative therapeutic option for unresectable case.
