Efficacy of Polarized Polychromatic Light Therapy on Acute Radiation Dermatitis in Breast Cancer Patients: A Randomized Controlled Trial
This assessor-blinded randomized controlled trial aims to evaluate the efficacy of polarized polychromatic non-coherent light therapy as an adjunct to standard skin care in reducing acute radiation dermatitis in women with breast cancer undergoing hypofractionated whole-breast radiotherapy. Participants will be randomly allocated to receive either standard skin care alone or standard care combined with polarized light therapy initiated from the first radiotherapy session. Outcomes will include objective ultrasound-based dermal thickness measurements, clinical severity of radiation dermatitis using Radiation Therapy Oncology Group (RTOG) criteria.
• Female patients aged 35-55 years.
• Histologically confirmed primary unilateral breast cancer.
• Status post breast-conserving surgery (lumpectomy).
• Planned for hypo fractionated whole-breast irradiation (HFWBI).
• Scheduled to receive a total radiation dose of 40-42.5 Gy delivered in 15-16 fractions over approximately 3 weeks.
• Ability to understand study procedures and provide written informed consent.
