Brief Summary

In recent years, an increasing number of retrospective and prospective observational studies have indicated that a subset of rectal cancer patients may avoid surgery if they can achieve a complete response to chemoradiotherapy. Prospective trials, including the previous Danish Watchful Waiting trials (NCT00952926, NCT02438839) in early rectal cancer have demonstrated high levels of organ preservation with dose-escalation, but it is unclear whether this was primarily due to tumor stage or dose level. The aim of the present study is to investigate if a higher dose of radiotherapy is superior compared to a standard dose in patients with early rectal cancer undergoing chemoradiotherapy with curative intent.
