EORTC QLQ-C30 will be summarized, both overall and at the ~12-week follow-up, according to participant characteristics and cancer groups. Overall change in QOL will be compared with paired tests and change according to groups will be compared using t-tests, ANOVA, or nonparametric tests. The EORTC QLQ-C30 is a 30-item core cancer specific questionnaire measuring QOL in cancer patients. It incorporates five functional scales (physical, role,cognitive, emotional, and social), three symptom scales (fatigue, pain, and nausea and vomiting), a global health status / QoL scale, and a number of single items assessing additional symptoms and perceived financial impact of the disease. Most questions used 4-point scale (1 'Not at All' to 4 'Very Much'); 2 questions used 7-point scale (1 'Very Poor' to 7 'Excellent'). Scores are averaged, and transformed to 0-100 scale; higher score=higher response level.
