Abstract

A 51-year-old male patient had four times of massive hematochezia episode three days before arrival. Carbohydrate antigen (CA) 19-9 level was extremely elevated. Computed tomography, magnetic resonance imaging, and positron emission tomography-computed tomography identified 5.7 cm sized periampullary duodenal cancer with regional metastatic lymph nodes and vascular invasion to aberrant right hepatic artery, main portal vein, and superior mesenteric vein. Diagnosed as duodenal adenocarcinoma through endoscopic biopsy, 16 times of FOLFIRI (5-fluorouracil, leucovorin, irinotecan) was conducted. The regimen changed to XELOX (capecitabine, oxaliplatine), four times of administration was done, and the CA19-9 level dramatically decreased. The tumor decreased to 2.1 cm. After R0 laparoscopic pylorus preserving pancreatoduodenectomy, no adjuvant therapy was given. No sign of recurrence or metastasis was reported, and the patient reached complete remission after five years. We reported a case where neoadjuvant chemotherapy for locally advanced duodenal adenocarcinoma was shown to be effective.
