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.
一名66岁女性因血清癌胚抗原（CEA）水平升高被转诊至我院胃肠病科。增强CT显示胰腺体部有一个低血供肿瘤。通过超声内镜引导下细针穿刺抽吸活检（EUS-FNA）诊断为胰腺癌。通过剖腹手术，我们在肠系膜和腹壁发现白色结节，诊断为腹膜转移。在接受9个疗程的吉西他滨（GEM）联合纳米白蛋白结合型紫杉醇（PTX）全身化疗以及30个疗程的改良FOLFIRINOX方案化疗后，肿瘤缩小，血清糖类抗原19-9（CA19-9）水平显著下降。作为挽救性手术进行了远端胰腺切除术。病理分析显示原发肿瘤和淋巴结中无残留癌细胞，证实达到病理完全缓解（pCR）。开始使用替吉奥（S-1）进行辅助化疗，术后8个月她仍存活且无复发。
