Abstract: Objective: To explore the application effect of a health management APP in improving the quality of life of patients with nasopharyngeal cancer receiving radiotherapy. Methods: 149 cases of nasopharyngeal cancer inpatients receiving concurrent radiotherapy and chemotherapy from December 2017 to August 2018 in the department of radiotherapy of a tertiary grade A hospital in Guangxi were selected as research objects, and were evenly divided into the control group and the observation group according to the random number table method. The control group was given routine health education in the radiotherapy department, while the observation group was given interventions based on the mobile medical APP aside from routine health education in hospital.The quality of life of patients in the two groups before radiotherapy, after radiotherapy for 15 times and after radiotherapy for 30 times were compared respectively using repeated measurement anova. Results : After intervention, there was no statistically significant difference between the observation group and the control group in the symptom scores of tooth problems, mouth opening difficulties, sticky saliva, oral nutrition and weight gain (P>0.05). However, the scores of other symptom fields of the observation group were all lower than those of the control group, and the difference was statistically significant (P<0.05). Conclusion: Health management based on the mobile medical APP can effectively relieve or alleviate adverse reactions of patients and improve their quality of life.
