NCT03051464

Brief Summary

A randomized study of 131 patients. Patients with a clinical T2-3 N0 rectal cancer will be randomized to two arms (arm A: standard chemoradiation (45 Gy in 25 with concomitant 5-FU or Xeloda chemotherapy) and an external beam boost of 9 Gy compared to arm B: standard chemoradiation (45 Gy in 25 with concomitant 5-FU or Xeloda chemotherapy) and followed by a brachytherapy boost of 30 Gy in 3 fractions).

Interventions

Patients that are complete responders will not have surgery. Patients that are non-complete responders will have surgery.
