[A Case of Descending Colon Cancer with Long-Term Maintenance of QOL by Multidisciplinary Treatment Approach for Locally Recurrent Lesion with Hydronephrosis].

ABSTRACT

We report a case of recurrent descending colon cancer in which QOL was maintained for a long period by performing resection with intestinal reconstruction, chemotherapy, and radiotherapy for local recurrence with hydronephrosis. A man in his 60s with good ADL underwent laparoscopic left hemicolectomy for descending colon cancer. After 4.5 years postoperatively, computed tomography and positron emission tomography showed a local recurrence of 32 mm contacting with the left external iliac artery and sigmoid colon, and CAPOX plus BEV was started. When cholecystitis developed after 5 chemotherapy courses, the recurrent lesion was resected simultaneously. After 8 months, repeated recurrent lesion with a major axis of 13 mm with left hydronephrosis was observed at the same site. After 3 years of chemotherapy after placing the left ureteral stent, CEA level gradually increased, and tumor growth was observed. Because of the aggressive chemotherapy limitation due to high proteinuria, 66 Gy/22 Fr radiotherapy was performed. After 1 month of radiotherapy, the CEA level decreased and proteinuria improved in that period. Radiotherapy for local recurrence can be a useful interval for chemotherapy and effective local control.
