The Effectiveness of Saline Soaks in Managing Acute Radiation Dermatitis

Radiotherapy is a cornerstone in the management of many malignancies, including sarcomas and head and neck cancers. Despite its therapeutic benefits, radiation-induced skin reactions remain one of the most common adverse effects, with the majority of patients developing some degree of acute radiation dermatitis (ARD). These reactions range from mild erythema to severe moist desquamation, which can lead to pain, increased risk of infection, impaired quality of life, and potential interruptions in treatment delivery. Such interruptions may negatively impact treatment efficacy and overall clinical outcomes.

Supportive skin care during radiotherapy is therefore essential. Current management strategies include general skin care measures, topical corticosteroids, moisturizers, and advanced wound dressings. However, there is no universally accepted standard intervention for preventing or managing ARD, and practices often vary across institutions.

Normal saline (0.9% sodium chloride) soaks are widely used in clinical settings as a supportive, non-pharmacological intervention for managing skin reactions. Saline soaks are believed to cleanse the affected area, soften crusted tissue, reduce surface bacterial load, and maintain a moist wound environment that supports re-epithelialization. In addition, they are low-cost, easy to administer, and suitable for home use, making them an attractive option for routine supportive care. Despite their frequent inclusion in clinical practice guidelines and institutional protocols, there is limited high-quality evidence specifically evaluating their independent effectiveness in reducing the severity of ARD.

This study is designed as an open-label, randomized clinical trial to evaluate the effectiveness of standardized normal saline soaks when used in addition to standard skin care in patients undergoing radiotherapy for sarcomas or head and neck cancers. Participants will be randomly assigned in a 1:1 ratio to receive either standard care alone or standard care plus saline soaks. Randomization will be conducted using a computer-generated sequence to ensure balanced group allocation.

The intervention consists of applying sterile gauze soaked in room-temperature normal saline (0.9% NaCl) to the irradiated skin area for a short duration on a daily basis. The procedure will be demonstrated by trained nursing staff in the clinical setting, and participants will be instructed on proper technique for safe and consistent application at home. Adherence to the intervention will be reinforced خلال follow-up visits.

Skin reactions will be assessed regularly during the course of radiotherapy using a standardized and validated grading system. Additional clinical observations related to skin healing and treatment continuity will also be documented. All participants will continue to receive routine clinical follow-up as part of standard oncology care, with no additional visits required solely for research purposes.

This study aims to address an important gap in the evidence regarding a commonly used supportive care intervention. By evaluating the clinical impact of saline soaks in a controlled and systematic manner, the findings may help determine whether this approach provides measurable benefits beyond standard care alone. The results of this trial have the potential to inform clinical practice, contribute to the development of evidence-based guidelines, and support the implementation of accessible, cost-effective strategies for managing radiation-induced skin toxicity.
