Importance: Previous studies have demonstrated the advantages of short-term histopathological outcomes and complications associated with transanal total mesorectal excision (TME) compared with laparoscopic TME. However, the long-term oncological outcomes of transanal TME remain ambiguous. This study aims to compare 3-year disease-free survival of transanal TME with laparoscopic TME.
Objective: To evaluate 3-year disease-free survival between transanal TME and laparoscopic TME in patients with rectal cancer.
Design, setting, and participants: This randomized, open-label, noninferiority, phase 3 clinical trial was performed in 16 different centers in China. Between April 2016 and June 2021, a total of 1115 patients with clinical stage I to III mid-low rectal cancer were enrolled. The last date of participant follow-up was in June 2024.
Interventions: Participants were randomly assigned in a 1:1 ratio before their surgical procedure to undergo either transanal TME (n = 558) or laparoscopic TME (n = 557).
Main outcomes and measures: The primary end point was 3-year disease-free survival, with a noninferiority margin of -10% for the comparison between transanal TME and laparoscopic TME. Secondary outcomes included 3-year overall survival and 3-year local recurrence.
Results: In the primary analysis set, the median patient age was 60 years. A total of 692 male and 397 female patients were included in the analysis. Three-year disease-free survival was 82.1% (97.5% CI, 78.4%-85.8%) for the transanal TME group and 79.4% (97.5% CI, 75.6%-83.4%) for the laparoscopic TME group, with a difference of 2.7% (97.5% CI, -3.0% to 8.1%). The lower tail of a 2-tailed 97.5% CI for the group difference in 3-year disease-free survival was above the noninferiority margin of -10 percentage points. Furthermore, the 3-year local recurrence was 3.6% (95% CI, 2.0%-5.1%) for transanal TME and 4.4% (95% CI, 2.6%-6.1%) for laparoscopic TME. Three-year overall survival was 92.6% (95% CI, 90.4%-94.8%) for transanal TME and 90.7% (95% CI, 88.3%-93.2%) for laparoscopic TME.
Conclusions and relevance: In patients with mid-low rectal cancer, 3-year disease-free survival for transanal TME was noninferior to that of laparoscopic TME.
