With the use of the European Organization for Research on Treatment of Cancer, the most widely used guideline in clinical practice, The EORTC Quality of Life Core Questionnaire (QLQ-C30) was used to evaluate the quality of life of patients.A total of 30 items and 15 domains were included, including 5 functional domains, 9 symptom domains and 1 general health/quality of life domain. Among them, the general health status/quality of life domain was divided into 7 grades, which were calculated from 1 to 7 points according to the answer options. Other items were on a 4-point scale, and "never", "a little", "a lot" and "a lot" were scored from 1 to 4 respectively. The domain score was obtained by summing the item scores included in each domain and dividing by the number of items included, ranging from 0 to 100. A lower score indicates a better quality of life.
