Health-related Quality of Life
Time frame: Change from Baseline (at diagnosis) to 1-3 days before the beginning of radiotherapy
Assessed by the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). This is a patient-reported questionnaire composed of both multi-item scales and single-item measures. These include 5 functional scales, 3 symptom scales, a global health status / QoL scale, and 6 single items. All of the scales and single-item measures range in score from 0 to 100. A high score for a functional scale represents a high / healthy level of functioning, a high score for the global health status/QoL represents a high QoL, but a high score for a symptom scale/item represents a high level of symptomatology/problems.
