Abstract

Background: This study aimed to compare the overall and disease specific survivals of patients who underwent laparoscopic and open resection of colorectal cancer in a high volume tertiary center.

Methods: Consecutive patients who underwent elective resection for colorectal cancer (open resection, n = 1,197; laparoscopic resection, n = 814) from January 2000 to December 2009 were included. The operative details, postoperative complications, postoperative outcomes, and survival data were collected prospectively. Comparison was made between patients who had laparoscopic and open surgery.

Results: The age, gender, medical morbidity, and American Society of Anesthesiologists status were similar in the two groups. Laparoscopic resection was associated with significantly less blood loss and a shorter hospital stay. The operating mortality and morbidity were significantly lower in the laparoscopic group. The qualities of the specimens in terms of the distal resection margin and the number of lymph nodes examined were not inferior in the laparoscopic group. With the median follow-up of 40.3 months, the 5-year overall survival (74.1% vs. 65.5%, p < 0.001) and disease specific survival (81.9% vs. 75.2%, p = 0.002) were significantly better in patients with non-disseminated disease in the laparoscopic group. The operative approach was an independent prognostic factor in the overall (risk ratio 1.36, 95% CI 1.093-1.700, p = 0.006) and disease specific (risk ratio 1.32, 95% CI 1.005-1.738, p = 0.048) survivals in multivariate analysis.

Conclusion: Laparoscopic resection for colorectal cancer is associated with more favorable overall and disease specific survivals when compared with open resection in a high volume tertiary center.
