[A Case of Mediastinal Lymph Node Metastasis from Liver Metastasis of Colon Cancer].

A 64-year-old woman underwent partial colectomy with partial resection ofthe retroperitoneum and D3 lymphadenectomy for descending colon cancer(tub2, pSS, ly0, v0, pN1, sH0, sP0, sM0, fStage III b). Three years and 6 months later, she underwent resection ofsegment 4 ofthe liver because ofliver metastasis. One year and 2 months later, her serum carcinoembryonic antigen level increased, and computed tomography showed an inferior mediastinal mass of 18mm in diameter.

[A case of advanced colon cancer with atrial fibrillation and the use of dabigatran for safe chemotherapy using fluoropyrimidine-based antitumor agents].

A 77-year-old man with colon cancer and multiple metastases to the liver and lungs underwent resection of the primary tumor and D3 lymph node dissection. He presented with chronic atrial fibrillation; therefore, warfarin was used initially as an anticoagulant. Because of the need to administer a fluoropyrimidine-based antineoplastic agent[5-fluorouracil(5-FU)] during chemotherapy, we changed the anticoagulant from warfarin to dabigatran etexilate(dabigatran)before initiating chemotherapy.

[A case of complete response treated by gastrectomy with lymphadenectomy and combined chemotherapy of peroral S-1 and CDDP by arterial infusion for gastric cancer with multiple liver metastasis].

A 70-year-old female was admitted to our hospital with high fever about 5 days before this writing, along with anemia and hyperglycemia. Upper gastrointestinal series and endoscopy revealed type 1 gastric cancer in the greater curvature. CT and MRI showed multiple liver metastasis in the right lobe.
