Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of the present study is to investigate whether curative chemoradiation of low rectal cancer is feasible, safe and effective in a multicenter study with results comparable to those of single center studies.

Results from previous studies indicate that a considerable fraction of patients with low rectal cancer can be cured by a combination of radiation and chemotherapy alone and thus be spared from operation.
