Outcomes of Routine Intensity Modulated Radiation Therapy Quality Assurance in a Large Head and Neck Cancer Center

Abstract

Purpose: The primary endpoint was to ascertain whether the percentage of major changes implemented from our routine intensity modulated radiation therapy (IMRT) quality assurance (QA) process was more than 10%. The secondary endpoints were to document the percentage of minor changes, ascertain the time taken to perform the IMRT QA process, evaluate potential predictors for major changes, and ascertain the perceived value of the program by the compliance of radiation oncologists (ROs) treating head and neck cancer (HNC). Methods and Materials: This was a retrospective analysis of a prospective database for all radically treated HNC patients. Recommended changes were predefined with criteria a..
