ABSTRACT
The patient was a 70-year-old man. He was diagnosed with advanced transverse colon cancer. A computed tomography (CT)revealed liver metastasis and tumor thrombosis of portal vein. We started combination chemotherapy with capecita- bine/oxaliplatin(CapeOX). Perforation of the tumor was observed 5 days after CapeOX therapy was started. Treatment with abscess drainage and ileostmy, infection was controlled and general condition was improved. After 9 courses of CapeOX, we changed chemotherapy regimen to irinotecan/tegafur-gimeracil-oteracilpotassium (IRIS)due to strong side effects. In CT and FDG-PET examination after 8 courses of IRIS, the tumor of transverse colon, liver metastasis, and the tumor thrombosis of portalvein became unclear. A year and 6 months have passed since chemotherapy was started, recurrence was not observed. For the patients with unresectable colorectal cancer, it is necessary to consider multidisciplinary treatments including chemotherapy while considering the general condition of them.

We report a case of recurrent transverse colon cancer invading the pancreas and duodenum that was successfully treated with biliary and duodenal stenting. A 46-year-old man underwent ascending colostomy for the treatment of obstructive transverse colon cancer with hepatic metastasis. Chemotherapy achieved a partial response, but the levels of tumor markers later began to rise again. He then underwent right hemicolectomy and partial hepatectomy. Post-operative chemotherapy was administered, but the recurrent tumor caused obstructive jaundice and duodenal obstruction. These were successfully treated with biliary and duodenal stenting, and the patient was able to remain at home and maintain his quality of life.

A 51-year-old male patient visited our hospital with a complaint of anal dysfunction and anal pain. Colonoscopy revealed a lower rectal cancer just above the dentate line, and its biopsy showed endocrine cell carcinoma. Enhanced computed tomography( CT) showed pararectal and right inguinal lymph node metastasis. Leucovorin, 5-fluorouracil, and oxaliplatin (FOLFOX) therapy was initiated first; then, after K-RAS was found to be wild type, 6 courses of FOLFOX plus panitumumab were administered. After the chemotherapy, the main tumor and the lymph node swelling reduced evidently. Its effect was judged as a partial response (PR). Laparoscopic assisted intersphincteric resection, right inguinal lymph node dissection, and temporary ileostomy were performed. The pathology revealed endocrine cell carcinoma (MP, ly2, v2, n0, stage II). Its pathological effect was judged as Grade 1b. Five months after the surgery, the ileostomy was closed.
