Abstract
Purpose: The long-term results of a laparoscopic resection for colorectal cancer have been reported in several studies, but reports on the results of laparoscopic surgery for rectal cancer are limited. We investigated the long-term outcomes, including the five-year overall survival, disease-free survival and recurrence rate, after a laparoscopic resection for colorectal cancer. Methods: Using prospectively collected data on 303 patients with colorectal cancer who underwent a laparoscopic resection between January 2001, and December 2003, we analyzed sex, age, stage, complications, hospital stay, mean operation time and blood loss. The overall survival rate, disease-free survival rate and recurrence rate were investigated for 271 patients who could be followed for more than three years. Results: Tumor-node-metastasis (TNM) stage I cancer was present in 55 patients (18.1%), stage II in 116 patients (38.3%), stage III in 110 patients (36.3%), and stage IV in 22 patients (7.3%). The mean operative time was 200 minutes (range, 100 to 535 minutes), and the mean blood loss was 97 mL (range, 20 to 1,200 mL). The mean hospital stay was 11 days and the mean follow-up period was 54 months. The mean numbers of resected lymph nodes were 26 and 21 in the colon and the rectum, respectively, and the mean distal margins were 10 and 3 cm. The overall morbidity rate was 26.1%. The local recurrence rates were 2.2% and 4.4% in the colon and the rectum, respectively, and the distant recurrence rates were 7.8% and 22.5%. The five-year overall survival rates were 86.1% in the colon (stage I, 100%; stage II, 97.6%; stage III, 77.5%; stage IV, 16.7%) and 68.8% in the rectum (stage I, 90.2%; stage II, 84.0%; stage III, 57.6; stage IV, 13.3%). The five-year disease-free survival rates were 89.8% in the colon (stage I, 100%; stage II, 97.7%; stage III, 74.2%) and 74.5% in the rectum (stage I, 90.0%; stage II, 83.9%; stage III, 59.2%). Conclusion: Laparoscopic surgery for colorectal cancer is a good alternative method to open surgery with tolerable oncologic long-term results. © 2011 The Korean Society of Coloproctology.
