PURPOSE: The aim of this study was to compare the long-term outcomes of laparoscopic surgery with those of open surgery in patients with stage Ι∨ colorectal cancer.
BACKGROUND: Laparoscopic resection has also developed as a commonly accepted surgical procedure for advanced colorectal cancer. There are conflicting data on the influence of laparoscopic surgery on survival benefits. However, advantages of primary tumor resection by the laparoscopic surgery in patients with stage Ι∨ colorectal cancer are still obscure.
METHODS AND PROCEDURES: We retrospectively reviewed a total 130 consecutive stage Ι∨ patients who underwent primary tumor resection of colorectal cancer between January 2007 and December 2013.
RESULTS: Of 130 patients, 29 underwent laparoscopic surgery and 101 underwent open surgery. The median duration of observation was 22.5 ±23.4 months. The five-year overall survival rate was 13.8% in all patients with stage Ι∨ colorectal cancer, with median survival times of 26 months. There were no deaths within 30 days after surgery in the laparoscopic group. Five patients (17.2%) in the laparoscopic group required conversion to open surgery because of bulky tumors. The five-year overall survival rate was 6.9% in the laparoscopic group and 15.8% in the open group, with median survival times of 34 and 23 months, respectively (P = 0.17). Although the median survival times of laparoscopic surgery were longer than open surgery, laparoscopic surgery was not significantly associated with the overall survival.
CONCLUSION: Laparoscopic surgery seems to be a safe and feasible option, with long-term benefit for primary tumor resection with stage Ι∨ colorectal cancer, although the difference was not statistically significant.
