| European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Health Status (EORTC-QLQ-C30). | 48 weeks | European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Health Status (EORTC-QLQ-C30).Minimum and maximum values is according to the items, the score range of item 1-28 is 1-4, the score range of item 29-30 is 1-7. The higher the overall score is, the better the overall quality of life is. |
