RESUMO
A 66-year-old woman was referred to the gastroenterology division of our hospital due to elevation of serum CEA level. Contrast-enhanced CT showed a hypovascular tumor at the body of pancreas. She was diagnosed with pancreatic cancer by EUS-FNA. By laparotomy, we found white nodules on mesentery and abdominal wall, which were diagnosed as peritoneal metastasis. After systemic chemotherapy with 9 courses of gemcitabine(GEM)plus nab-paclitaxel(PTX)and 30 courses of mFOLFIRINOX, the tumor had shrunk and serum CA19-9 level were remarkably decreased. Distal pancreatectomy was performed as conversion surgery. Pathological analysis revealed no remnant cancer cells in the primary tumor or the lymph nodes, confirming a pCR. S-1 was started as adjuvant chemotherapy, and she remains alive without recurrence 8 months after surgery.
