A 62-year-old woman was admitted for epigastralgia, nausea and tarry stool.Abdominal CT showed a tumor to the jejunum from the duodenum, and peritoneal dissemination.Gastroduodenoscopy showed a type 2 tumor, and the histopathological examination revealed a well-to moderately-differentiated adenocarcinoma.Accordingly, she was diagnosed with primary adenocarcinoma of the small intestines and underwent surgery.The first-line chemotherapy with S-1/CPT-11 was started after surgery, and the tumor marker returned to normal.The treatment of 14 courses was continued until PD due to the enlargement of the peritoneal dissemination.Second - and third-line chemotherapy were performed; however, she died 20 months after the initial treatment.Although the incidence of primary adenocarinoma of the small intestines is relative- ly low, and there is no established chemotherapy at present, this case suggested that S-1/CPT-11may be an effective regimen for advanced primary adenocarcinoma of the small intestines.

We present a case of gastric cancer with portal vein tumor thrombosis. A 77-year-old man visited our hospital because of epigastric pain. Esophagogastroduodenoscopy and computed tomography (CT) revealed advanced gastric cancer. Total gastrectomy was performed. During surgery, peritoneal dissemination was found. Histopathological diagnosis was Stage IV gastric cancer (por2, T4aN3M1) with massive vascular invasion. He was treated with a chemotherapy regimen of S-1 plus docetaxel for approximately 2 years after which the regimen was changed to S-1 monotherapy. Six months later, CT revealed portal vein tumor thrombosis (PVTT) without progression of peritoneal dissemination. The metastatic route of PVTT was believed to be hematogenous because neither liver nor lymph node metastasis was detected. The regimen was shifted to CPT- 11 plus cisplatin therapy since the effects of the treatment was evaluated as progressive. The patient was alive with stable disease after 5 courses of chemotherapy. PVTT should be taken into consideration as a possible type of recurrence when the tumor is associated with massive vascular invasion, although gastric cancer with PVTT is rare.
