title: [A case of unresectable advanced pancreatic cancer with peritoneal dissemination responding to continuous dose S-1 monotherapy after chemo-radiation therapy].
abstract: A 57-year-old woman with a pancreatic body tumor was admitted to our hospital. She was diagnosed with unresectable advanced pancreatic cancer (stage IVb) due to portal vein invasion, arterial invasion, retro peritoneal invasion and lymphnode metastases, so radiation therapy (50 Gy/25 Fr) with concurrent arterial infusion of gemcitabine (GEM) was carried out. After the chemo-radiation therapy, her arterial infusion treatment of GEM was continued in our outpatient clinic for 3 months until she was complicated with ascites due to peritoneal dissemination. Peritonitis carcinomatosa was controlled by S-1 oral administration with intraperitoneal infusion of MMC and CDDP. For 18 months after discharge, she has maintained good quality of life without any adverse effects by a continuous dose of S-1 at our outpatient clinic.
