Efficacy and Safety of Hyperbaric Oxygen Therapy for Radiation Dermatitis in Patients with Localized Breast Cancer

To evaluate the efficacy of hyperbaric oxygen therapy (HBOT) on the prevention of radiation dermatitis, patients with localized breast cancer between the ages of 19 and 69 were randomly assigned to HBOT group and usual care group in a 1:1 ratio during the period of adjuvant radiotherapy. The primary purpose of this study was to administer oxygen therapy three times a week during the radiotherapy period for those who were recommended to receive radiotherapy with a Biological equivalent dose (BED10) of 60 Gy or more as adjuvant radiotherapy after breast-conserving surgery to determine the radiation at the end of radiotherapy. The purpose is to compare the incidence of radiation dermatitis of therapy oncology group grade (RTOG grade) grade 2 or higher between the two groups. The secondary purpose of this study is to evaluate/compare the following items in the relevant treatment group. 1. Comparison of the incidence of radiation dermatitis according to RTOG grade 2. Catterall skin scoring profile score comparison 3. Comparison of Skindex-29 questionnaire scores 4. Numeric rating scale score comparison 5. Investigation of radiation therapy dose, frequency, schedule, and medical history 6. Health-related quality of life questionnaire (EORTC-QLQ-C30) 7. Health-related quality of life measurement tool (EQ-5D) 8. Safety evaluation 9. Health-related quality of life measurement tool (EQ-5D)
