Robotic and laparoscopic rectal cancer surgery show similar 5-year outcomes

The COLRAR randomized trial compared 5-year oncological outcomes of robotic versus laparoscopic total mesorectal excision in 295 patients with rectal adenocarcinoma. The trial reported no significant differences in overall survival, relapse-free survival, or distant recurrence-free survival between the two approaches. A post-hoc analysis of patients who received neoadjuvant chemoradiotherapy suggested better local recurrence-free survival with robotic surgery, a finding the authors state requires confirmation in prospective studies.

Most relevant for: Patients with rectal cancer undergoing total mesorectal excision, including those receiving neoadjuvant chemoradiotherapy.
