{"anticipatedPostingDate":"2026-08","denomUnitsSelected":"Participants","description":"The EORTC QLQ-C30 is a validated and reliable self-report measure consisting of 30 questions incorporated into five functional scales (physical, role, cognitive, emotional, and social scales), three symptom scales (fatigue, pain, nausea, and vomiting scales), and a global health status/global quality-of-life scale. The remaining single items (dyspnea, appetite loss, sleep disturbance, constipation, and diarrhea) assess the additional symptoms experienced by patients with cancer and the perceived financial burden of treatment. The 28 function and symptom items were scored on a 4-point scale that ranged from \"not at all\" to \"very much,\" and the 2 global health status/global quality-of-life items were scored on a 7-point scale that ranged from \"very poor\" to \"excellent.\" Raw average scale scores were linearly transformed to range 0-100 with higher scores indicating higher response levels (i.e., higher functioning, higher symptom severity).","reportingStatus":"NOT_POSTED","timeFrame":"Baseline up to approximately 10.75 years","title":"Change From Baseline in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQC30)","type":"SECONDARY"}
