title: [Sigmoid colon cancer with a tumor thrombosis in the splenic vein--a case report].
abstract: A 63-year-old woman was admitted to the hospital for investigation of abdominal discomfort. Further examination revealed that she had sigmoid colon cancer. The serum CEA level was 20.1 ng/ml, and the CA19-9 level was 8.9 U/ml. Laparotomy findings showed H0, P0, and lymph-nodes swelling observed at LN253-LN16b2. Massive tumor thrombosis was present in IMV, the splenic vein, and the advanced region in the portal vein. Metastatic tumor was present in the pancreas body. An anterior resection of the colon combined with resection of lymph nodes, pancreas body and tail and spleen were performed. Resection of IMV and splenic vein including tumor thrombosis was performed prudently. Histological examination revealed that the pancreas tumor and tumor thrombosis were of the same origin (moderately differentiated from adenorarcinoma), and massive LN metastases existed. Post operative chemotherapy, an oral administration of UFT/UZEL, was performed. After 24 months of operation, there has been no sign of recurrence detected.
