Abstract
The local recurrence rate after rectal cancer surgery is discussed as related to conventional and total mesorectal excision (TME) techniques. Studies now show that the wide variation in results between centers and among surgeons depends, at least in part, on differences in surgical technique. We conclude that local tumor recurrence rate is lower after TME than after conventional surgery and emphasize the importance of a standardized macroscopic evaluation of the resected specimen. Population-based registration to evaluate the quality of surgery is recommended. It is also suggested that randomized studies on adjuvant treatment for rectal cancer should include a “surgery only” arm when a local tumor recurrence rate of 10% or less is being studied. Until such investigations are performed, we conclude that the role for adjuvant treatment is questionable and that TME surgery is preferred as the treatment option for Stage T1–T3 rectal cancers.
