Altered fractionation diminishes importance of tumor volume in oropharyngeal cancer : Subgroup analysis of ARTSCAN-trial
BACKGROUND: A large tumor volume negatively impacts the outcome of radiation therapy (RT). Altered fractionation (AF) can improve local control (LC) compared with conventional fractionation (CF). The aim of the present study was to investigate if response to AF differs with tumor volume in oropharyngeal cancer.METHODS: Three hundred and twenty four patients with oropharyngeal cancer treated in a r
