What was measured

Time to deterioration of HRQoL was defined as time to 10-point decrease in the global health status/QoL scale of the European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaire (QLQ-C30). EORTC QLQ-C30 is 30 item questionnaires composed of 5 multi-item functional domains (physical, role, cognitive, emotional, and social), 3 symptom scales (fatigue, pain, nausea, and vomiting) and 6 single items for symptoms (shortness of breath, loss of appetite, sleep disturbance, constipation, diarrhea and financial impact of the disease), 2 global items (health, overall QoL). Higher functional/global QoL score = better functioning and higher symptom score = greater degree of symptoms.
