Association Between Toxicity Profiles During Radiation Therapy (RT) for Oropharyngeal Cancer and CBCT-Derived and Dosimetric Factors to Evaluate Global Toxicity During RT for Oropharyngeal Cancer

To evaluate changes in morphology and density for Organs at Risk (OAR) as assessed by kV Cone Beam Computed Tomography (CBCT) images and study association of CBCT-derived (CBCT-d) and dosimetric parameters with acute toxicity profiles during Oropharyngeal cancer (OPC) radiotherapy (RT). Consecutive non-metastatic OPC pts curatively treated between 2012-2013 with Volumetric Modulated Arc Therapy and imaged with daily CBCT were considered. Oral...
