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

PRO-CTCAE demonstrates strong content validity as a measure of symptomatic toxicities in patients receiving radiation. These results provide empirical support for the definition of site-specific PRO-CTCAE item sets to assess the symptomatic toxicities of radiation therapy. The site-specific PRO-CTCAE item sets developed herein are currently being deployed in our department via an electronic platform to capture treatment-related toxicity.
