[A case of 5-year survival with combination chemotherapy for advanced colonic cancer with multiple lung and liver metastases and peritoneal dissemination].

: A 74-year-old man was admitted to the hospital because of abdominal fullness and constipation. Endoscopy and abdominal computed tomography (CT) scans showed an advanced sigmoid colonic cancer with multiple lung and liver metastases and peritoneal dissemination. Sigmoid resection was performed to relieve ileus. Postoperative chemotherapy was administered for metastatic lesions. We administered systemic chemotherapy with tegafur-uraci(l UFT)/UZEL( 10 months), oxaliplatin with fluorouracil (5-FU) and folinic acid (FOLFOX; 11 courses), irinotecan with 5-FU and folinic acid (FOLFIRI; 13 courses), irinotecan plus S-1 (IRIS; 23 courses), bevacizumab (32 courses), cetuximab (29 courses), and peritoneal infusion of paclitaxel( 65 courses). The patient survived for 5 years after the initial treatment.
