Résumé
Background
Long-term oncological equivalence of robotic total mesorectal excision (R-TME) and laparoscopic total mesorectal excision (L-TME) remains unproven. The 5-year outcomes of the COLRAR RCT are reported.
Methods
Adults with cT1-4a Nx M0 rectal adenocarcinoma within 10 cm of the anal verge were randomized 1 : 1 to L-TME or R-TME at three Korean tertiary centres between July 2011 and February 2016. Pre-specified secondary endpoints were 5-year overall, relapse-free, local recurrence-free, and distant recurrence-free survival. Analyses were on a modified intention-to-treat basis.
