Content validity of anatomic site-specific Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) item sets for assessment of acute symptomatic toxicities in radiation oncology

The Patient Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) has not previously been validated in a site-specific manner as would be relevant to patients undergoing radiation therapy. We evaluated the content validity of PRO-CTCAE in a diverse sample of patients undergoing radiation therapy. We found strong content validity of the PRO-CTCAE, and herein we propose site-specific item sets for further validation in prospective trials.
