Open versus laparoscopic surgery for mid or low rectal cancer after neoadjuvant chemoradiotherapy (COREAN trial): 10-year follow-up of an open-label, non-inferiority, randomised controlled trial. Lancet Gastro Hepatol 2021; 6: 569-577.

Published: 9th December 2021

Authors: Park JW, Kang S-B, Hao J, Lim S-B, Choi HS, Kim D-W et al.

Conclusion

Median follow-up in this trial that enrolled 340 patients was 143 months. Overall 10-year survival rates were similar: 74.1 per cent open and 76.8 per cent laparoscopic surgery (P=0.44). Local recurrence rates were lower after laparoscopic surgery (3.4 versus 8.9 per cent; P=0.05), but disease-free survival rates were similar.
