This study aimed to evaluate reducing the incidence of radiation dermatitis by assigning hyperbaric oxygen therapy to 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.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| HBOT group | Experimental | Hyperbaric oxygen therapy allows the patient to breathe 100% oxygen through an O2 Fresh M50 (HBOT Medical, Wonju, South Korea) chamber. Upon entering the chamber, oxygen is supplied while gradually increasing the atmospheric pressure from normal atmospheric pressure to 1.5 atmospheres absolute (ATA). If the intensity acceptable to the clinical research subject is lower than 1.5 ATA, maintain it at the point acceptable to the research subject and record that value. |
|
| control group | No Intervention | The control group will receive systemic education in dermal care and will be under the instruction of usual self-care. |

| hyperbaric oxygen chamber | Device | Hyperbaric oxygen therapy allows patients to breathe 100% oxygen through an O2 Fresh M50 (HBOT Medical, Wonju, South Korea) chamber. Upon entering the chamber, oxygen is supplied by gradually increasing the barometric pressure from normal pressure to 1.5 atmospheres absolute (ATA). |

| CSSP | CSSP is a numerical scale-type evaluation tool developed by Fowler in 1965 to evaluate skin reactions in rats and modified by Catterall for application to patients with radiotherapy-induced dermatitis. [14] Graded from 1 to 10 points depending on the symptoms and severity of dermatitis | At the end of Day 1, week 5, week 8, week 9, week 10 |
| skindex-29 | Skindex-29 is a revision of the existing 61-item Skindex to 29 questions for patients with skin diseases. It maintains the excellent reproducibility, reliability, construct validity, and content validity of the Skindex, while improving the patient's quality of life through symptoms, function, and quality of life. It is a quality of life assessment tool designed to evaluate emotions on three scales. It consists of three scales: function (Fx), emotion (em), symptom (symptom) and a total score (total), linearly ranging from 0 (not affected) to 100 (always affected). A total of 29 items are scored for each scale, and then averaged to calculate the overall quality of life. The lower the score of Skindex-29, the better the quality of life. | At the end of Day 1, week 5, week 8, week 9, week 10 |
| NRS | NRS is one of the evaluation tools that quantifies the level of discomfort. NRS 0 is defined as no discomfort, and NRS 10 is defined as the maximum discomfort the patient can think of. | At the end of Day 1, week 2, week 3, week 4, week 5, week 6, week 7, week 8, week 9, week 10 |
| EORTC | This is a questionnaire developed with 30 questions to measure the general quality of life of tumor patients. It evaluates overall quality of life and emotional health by dividing it into five areas: physical, role, cognitive, emotional, and social. | At the end of Day 1, week 5, week 8, week 9, week 10 |
| EQ-5D | It is the most widely used method of indirect measurement among various indirect measurement methods as it evaluates health status from multiple aspects, and then indirectly calculates the weight of the quality of a specific health status using a preference score assigned in advance for each functional level. The EQ-5D-5L consists of five questions, each of which asks about mobility, self-care, usual activities, pain, and anxiety/depression. | At the end of Day 1, week 5, week 8, week 9, week 10 |
| Drug Consumption | The type, dose, route of administration, frequency, and purpose of medications administered or taken during the study period (medications prescribed due to current medical history or rescue drugs) will be recorded. | At the end of Day 1, week 2, week 3, week 4, week 5, week 6, week 7, week 8, week 9, week 10 |
| Adverse events | To compare the occurrence of adverse events between the two groups and verify their safety. An adverse event is an undesirable or unintended sign, symptom, or disease that occurs after a procedure in a clinical study and does not necessarily have a causal relationship with the procedure. The investigator will analyze the incidence of adverse events, laboratory abnormalities, and serious adverse events that are suspected to be associated with treatment. | At the end of Day 1, week 2, week 3, week 4, week 5, week 6, week 7, week 8, week 9, week 10 |
