COSTAR: A Multicentre Randomised Study of Cochlear Sparing Intensity Modulated Radiotherapy Versus Conventional Radiotherapy in Patients with Parotid Tumours. 

Disease site: Head and neck

Treatment modality: Radiotherapy

Status: Closed

Trial details

COSTAR is a phase III multi-centre randomised controlled trial designed to demonstrate a difference in the proportion of patients suffering sensori-neural hearing loss of at least 10dB in bone conduction at 4000 Hz, as assessed by an audiogram done 12 months post radiotherapy, in patients treated with cochlea-sparing IMRT and conventional radiotherapy.

The work is supported by the NCRI CTrad Group and the NCRI Head and Neck Cancer Studies Group.

Chief Investigator: Dr Chris Nutting, The Royal Marsden NHS Foundation Trust
