Scientific title	A randomised controlled trial of radical radiotherapy alone versus radical surgery plus radical radiotherapy for patients with cancer of the oral cavity
Study objectives	Not provided at time of registration
Ethics approval(s)	Not provided at time of registration
Health condition(s) or problem(s) studied	Head and neck cancer
Intervention	1. Arm A: Radical radiotherapy to the primary tumour and to the anterior triangles of the neck. 2. Arm B: Radical surgery involving wide local excision of the intra oral tumour with approximately a 1 cm margin and immediate reconstruction of the oral cavity. Neck dissection should be performed either for access to the oral cavity or for clearance of suspected clinically positive nodes. Following surgery patients receive radical radiotherapy to the primary tumour and to the anterior triangles of the neck.
