Two independent reviewers select samples by screening and reviewing articles and extract data using a data chart form. The protocol was registered in the Open Science Framework (OSF.)ResultsA total of 16 articles were included to analyze and integrate the use of medical ozone, medical ozone dose, symptom assessment tools, and symptom management.ConclusionThe effectiveness of medical ozone treatment in managing key symptoms (including Pain, Fatigue, Anxiety, and Depression) among cancer patients has been preliminarily verified. Future studies need to cover a wider range of areas and larger sample sizes, as well as conduct long-term follow-up studies and multi-dimensional evaluation to enhance the universality and reliability of the results.
