Oncological outcome of laparoscopic surgery for advanced colon cancer: a community hospital's experience.

Background/Aims: Similar oncological outcomes of laparoscopic and open surgery for advanced colon cancer have been reported by several large-scale studies. Whether those results are applicable to community hospitals is questionable. Methodology: From January 2007 to December 2010, 95 patients with colon cancer underwent laparoscopic surgery at Seirei Mikatahara General Hospital. Of these, 40 patients with pathological stage II/III colon cancer were subjected to this retrospective analysis (laparoscopic resection (LAP) group). Their outcomes were compared with those of 58 patients with pathological stage II/III colon cancer who underwent open surgery between January 2005 and, December 2006 (open resection (OP) group). Results: Surgical complications were significantly less frequent in the LAP group than in the OP group. Three-year disease-free survival (DFS) and overall survival (OS) for stage II colon cancer were 88.9% and 100% in the LAP group, and 90% and 86.7% in the OP group (p=0.976 and p=0.285), respectively. Three-year DFS and OS for stage III colon cancer were 85.4% and 86.9% in the LAP group, and 75.3% and 83.8% in the OP group (p=0.613 and p=0.837), respectively. Conclusions: Laparoscopic surgery for advanced colon cancer seems feasible and the oncological outcome is adequate in a community hospital setting.
