We report a case of the pancreas head cancer with peritoneal metastasis, which was resected curatively after chemotherapy. A6 6-year-old male was referred to our hospital for the treatment of biliary stenosis. The serum CA19-9 level was elevated and abdominal CT scan showed stenosis of distal bile duct. By laparotomy, we noticed mass in the head of the pancreas with 8mm of the seeding nodule in a diameter at jejunal mesentery which was diagnosed as adenocarcinoma by intraoperative frozen sections. Therefore, the patient was diagnosed as pancreas head cancer with peritoneal metastasis. After hepaticojejunostomy, we started chemotherapy planning adjuvant surgery if the clinical response was observed. Systemic chemotherapy with gemcitabine and nab-paclitaxel was administrated on days 1, 8 and 15 every 4 weeks. After 5 courses, therapeutic effect was stable disease(SD)in response evaluation criteria in solid tumor(RECIST). All of tumor markers were normalized. Subtotal stomach-preserving pancreatoduodenectomy(SSPPD)was performed 6 months after the initial surgery. Histopathologically, most cancer cells showed degeneration and eliminated in the head of the pancreas. R0 resection was achieved with diagnosis of ypT3, ypN1, pM1(PER), Stage IV . Histological therapeutic effect was Grade III according to the Evans classification. The patient is alive, with no sign of recurrence 8 months after surgery. Adjuvant surgery was suggested to be one of the therapeutic options for pancreatic cancer with peritoneal metastasis.
