[A Case of Transverse Colon Cancer with Pancreatic Head and Gastric Invasion Treated with Radical Surgery after...

The patient was a 67-year-old woman who presented to our hospital with abdominal pain. She was diagnosed with transverse colon cancer with obstructive colitis, pancreatic head, and gastric invasion(cT4bN1bM0, cStage ⅢC). After the placement of a colonic stent to relieve the obstruction, 5 courses of preoperative chemotherapy(FOLFOXIRI+bevacizumab) were administered for local control. Tumor shrinking was observed, and the response was judged to be a partial response. Following a rest period, radical surgery(extended right hemicolectomy and pancreaticoduodenectomy)was performed. Pathological findings showed pT4b(panc)N1bM0, pStage ⅢC, and R0 resection was achieved. In cases of colon cancer invading other organs, long-term survival may be achievable with R0 resection, and we believe that extended surgery should be considered proactively.
