[A Case of Resected Pancreatic Adenosquamous Carcinoma with Early Hepatic Metastatic Recurrence]

A 73-year-old man was presented with epigastric pain and indicated high CA19-9 levels, and computed tomography detected a tumor in the uncinate process of the pancreas infiltrated duodenum and superior mesenteric artery. The patient was diagnosed with borderline resectable pancreatic carcinoma and received neoadjuvant chemotherapy with gemcitabine and S-1. During neoadjuvant chemotherapy, the patient also received radiotherapy to control duodenal bleeding. After neoadjuvant chemotherapy, stable disease(SD)was proven on the Response Evaluation Criteria in Solid Tumors(RECIST), and subtotal stomach-preserving pancreaticoduodenectomy was performed. The pathological findings showed pancreatic adenosquamous carcinoma. After 7 days postoperatively, hepatic metastasis was detected, and after 78 days postoperatively, the patient died.
