Randomized Trial of ARCON in Larynx Cancer
|ClinicalTrials.gov Identifier: NCT00147732|
Recruitment Status : Completed
First Posted : September 7, 2005
Last Update Posted : May 7, 2015
A multicentre, randomised, phase III clinical trial comparing accelerated radiotherapy with accelerated radiotherapy plus carbogen and nicotinamide (ARCON) in clinical stage T2-4 laryngeal carcinoma.
Does the addition of carbogen and nicotinamide to a schedule of accelerated radiotherapy in patients with clinical stage T2-4 laryngeal carcinoma improve local primary tumour control? Definitive analysis will be performed on local control rates at two years after completion of radiotherapy.
Does the addition of carbogen and nicotinamide
- increase the larynx preservation rate?
- increase the regional control rate?
- increase the toxicity of accelerated radiotherapy?
- improve the overall quality of life?
- improve the disease-free survival?
- improve the overall survival?
An open-label, randomised clinical trial assigning patients in a 1:1 ratio to one of the following treatment arms:
- accelerated radiotherapy
- accelerated radiotherapy plus carbogen and nicotinamide
PATIENT CHARACTERISTICS AND NUMBER:
344 patients with clinical T2-4 laryngeal carcinoma
- time to local failure
- time to regional failure
- survival with functional larynx
- overall and disease-free survival
- frequency and severity of complications related to radiotherapy and carbogen and nicotinamide
- quality of life assessment
