Quality of life assessed by the QLQ-C30 questionnaire. Quality of life was assessed immediately after inclusion into the study and at least once during the course of treatment, using the standardized EORTC QLQ-C30 questionnaire, version 2. Overall scores range from 0 to 100, divided into several subsets such as physical ability, emotional feelings, nausea/vomiting, fatigue, pain or diarrhea. Higher scores on global health status and physical functioning and lower scores on symptom scales and emotional assessment indicate a better quality of life.
