Comparison Study of Assessment of Symptom Distress in Cancer

Objective：This study is aimed to evaluate the change in symptom distress in cancer patients after radiotherapy and its predisposing factors. Methods： A longitudinal design was conducted on 126 cancer patients who underwent radiotherapy in Anhui Provicial hospital radiotherapy department. The structured questionnaire included sections on demographics, medical conditions, and a symptom distress scale. Results： Of the cancer patients, 60.32% reported an increase in the overall figures of symptom distress after radiotherapy, whereas 37.3% experienced a de- crease. Cancer patients 20 to 39 years old or who received radiotherapy on the head and neck reported the greatest increase in overall figure of symptom distress. Patients after radiotherapy on the head and neck experienced significant increase in bowel disturbance. Conclusion：Radiotherapy can increase symptom distress in all patients, but it is not the only factor.
