Patterns of Failure after Intensity-modulated Radiotherapy in Head and Neck Squamous Cell Carcinoma using Compartmental Clinical Target Volume Delineation

AimsTo determine the pattern of disease recurrence in non-nasopharyngeal head and neck squamous cell carcinoma (HNSCC) patients treated with radical intensity-modulated radiotherapy (IMRT) with or without chemotherapy, and to correlate the sites of locoregional recurrence with radiotherapy target volumes.Materials and methodsIn total, 136 patients treated with radical IMRT with or without chemotherapy between 2008 and 2011 for non-nasopharyngeal...
