Abstract

We report here a case of long-term survival with repeated peritoneal recurrences after resection of perforated sigmoid colon cancer. A 65-year-old man presented with diarrhea and abdominal pain. Computed tomography(CT)revealed diffuse peritonitis caused by perforated sigmoid colon cancer. We performed sigmoidectomy with D2 lymphadenectomy and descending colostomy. Postoperatively, S-1 was administered for 12 months as adjuvant chemotherapy. CT showed peritoneal nodules 56 months after the surgery. After 10 courses of mFOLFOX6 plus bevacizumab, the tumors decreased in size (reduction rate of 34.4%; a partial response). Subsequently, 3 peritoneal nodules were resected with curative intent. Another peritoneal nodule was detected 57 months after the second surgery. After 3 courses of XELOX plus bevacizumab, the nodule decreased in size(reduction rate of 69.0%; a partial response). The nodule was resected with a curative intent. At the last follow-up 135 months after the first surgery, the patient remains alive with no evidence of disease.
