Validity and Reliability Evaluation of the PRO-CTCAE for Adult-type Diffuse Gliomas Patients in Chinese Population

Given the increasing importance of patient's perspective in adverse events reporting, Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE™) has been proposed as new PRO measures in oncology; however, its implementation has not yet been evaluated in glioma patients, and standardized selection process of priority symptom terms has not been applied. The study focuses on Chinese adult-type diffuse glioma patients. First, based on information queries, expert consultation research, online Delphi survey, and survey data analysis, the investigators will determine the questionnaire terms for PRO-CTCAE™ for adult-type diffuse gliomas patients. In the next stage, a prospective, multi-center, real-world study to assess the validity, reliability, and responsiveness of the customized PRO-CTCAE™ for adult-type diffuse gliomas patients in Chinese population will be launched (VERONICA).
