Not Applicable

Completed

• Conditions: Breast Cancer; Radiation Dermatitis
• Interventions: Device: hyperbaric oxygen chamber

• Registration Number: NCT06158347
• Lead Sponsor: Ilsan Cha hospital

Brief Summary

This study aimed to evaluate reducing the incidence of radiation dermatitis by assigning hyperbaric oxygen therapy to patients with localized breast cancer.

Detailed Description

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)

Arm && Interventions

Group	Intervention	Description
HBOT group	hyperbaric oxygen chamber	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.

Primary Outcome Measures

Name	Time	Method
incidence of grade 2 or more dermatitis according to RTOG toxicity scale	At the end of 6 weeks	① Grade 0: No change before or after treatment (No change over baseline); * Grade 1: Cystic lesions, erythema with faint or reduced skin luster, implantation, dry epidermis shedding, and decreased sweating.; (Follicular, faint or dull erythema, epilation, dry desquamation, decreased sweating); * Grade 2: Tender or bright erythema, ecchymosis, desquamation of the wet epidermis, and moderate edema.; (Tender or bright erythema, patchy moist desquamation, moderate edema); * Grade 3: Confluent skin lesions, desquamation of the wet epidermis other than the area where the skin is folded, pitting edema (Confluent, moist desquamation other than skin folds, pitting edema); * Grade 4: Ulcerative bleeding, skin necrosis (Ulceration hemorrhage, necrosis)

Secondary Outcome Measures

Name	Time	Method
EQ-5D	At the end of Day 1, week 5, week 8, week 9, week 10	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.
skindex-29	At the end of Day 1, week 5, week 8, week 9, week 10	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.
RTOG toxicity	At the end of Day 1, week 2, week 3, week 4, week 5, week 6, week 7, week 8, week 9, week 10	① Grade 0: No change before or after treatment (No change over baseline); * Grade 1: Cystic lesions, erythema with faint or reduced skin luster, implantation, dry epidermis shedding, and decreased sweating.; (Follicular, faint or dull erythema, epilation, dry desquamation, decreased sweating); * Grade 2: Tender or bright erythema, ecchymosis, desquamation of the wet epidermis, and moderate edema.; (Tender or bright erythema, patchy moist desquamation, moderate edema); * Grade 3: Confluent skin lesions, desquamation of the wet epidermis other than the area where the skin is folded, pitting edema (Confluent, moist desquamation other than skin folds, pitting edema); * Grade 4: Ulcerative bleeding, skin necrosis (Ulceration hemorrhage, necrosis)
CSSP	At the end of Day 1, week 5, week 8, week 9, week 10	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
NRS	At the end of Day 1, week 2, week 3, week 4, week 5, week 6, week 7, week 8, week 9, week 10	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.
Drug Consumption	At the end of Day 1, week 2, week 3, week 4, week 5, week 6, week 7, week 8, week 9, week 10	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.
Adverse events	At the end of Day 1, week 2, week 3, week 4, week 5, week 6, week 7, week 8, week 9, week 10	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.
EORTC	At the end of Day 1, week 5, week 8, week 9, week 10	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.
