Background: Laparoscopic surgery for T4 colon cancer remains controversial according to many colorectal cancer guidelines. The aim of this study was to compare short- and long-term outcomes in patients who underwent T4 colon cancer resection by laparoscopy versus open surgery. Methods: Patients who underwent T4 colon cancer resection either by laparoscopy or by open surgery between January 2012 and January 2017 were included and used to perform a retrospective cohort analysis. Demographics, patient characteristics, short-term outcomes, and long-term oncological outcomes were compared between two groups. Multivariate analyses were used to define prognostic factors of overall survival. Results: Groups were comparable in terms of preoperative characteristics and demographics. Intraoperative blood loss (127.3 versus 226.1mL, P=.001) and hospital stay (11.6 versus 14.8 days, P=.001) were significantly reduced in the laparoscopic group compared with the open group. Operative time, bowel movement, time to soft diet, and lymph nodes harvested did not significantly differ between the two groups. R0 resection achieved 100% in both the groups. Similarly, the overall survival rate and disease-free survival rate in stage II and stage III disease showed no significant differences. Multivariate analyses showed that intraoperative blood loss was a significantly independent factor related to a poor prognosis. Conclusions: This study suggests that laparoscopy for T4 colon cancer can be safely performed with superior short-term outcomes, such as less intraoperative blood loss and shorter time of hospital stay compared with open surgery, and with similar long-term oncological outcomes. Therefore, laparoscopic procedure could be a viable option in selected patients.
