Gedetailleerde beschrijving
Radiotherapy (RT) is a cornerstone treatment for patients with head and neck cancer and may be administered as definitive, adjuvant, or concurrent therapy with chemotherapy depending on disease stage and clinical indication.
Despite its therapeutic benefits, RT is frequently associated with a range of acute toxicities, among which radiation dermatitis is one of the most common and clinically relevant adverse effects.
Radiation-induced skin injury may present during or shortly after the course of radiotherapy and can significantly impact patient comfort, treatment adherence, and overall quality of life.
Severe cases may lead to treatment interruption or dose modification, potentially compromising oncologic outcomes.
The incidence of acute radiation dermatitis in patients with head and neck cancer has been reported to be high, with a substantial proportion of patients developing at least moderate-grade skin reactions during the course of radiotherapy.
However, current preventive and therapeutic strategies remain limited, and no universally accepted standard of care has been established.
Existing supportive measures are primarily empirical and have shown variable efficacy in reducing the severity or progression of skin toxicity.
Superoxide dismutase (SOD) is an endogenous antioxidant enzyme with the ability to catalyze the dismutation of superoxide radicals into oxygen and hydrogen peroxide, thereby reducing oxidative stress-induced cellular damage.
Given that oxidative stress is a key mechanism underlying radiation-induced skin injury, topical application of SOD-based formulations may provide a biologically plausible approach for mitigating radiation dermatitis.
Based on this rationale, the present clinical trial is designed to investigate the efficacy and safety of a topical SOD skin spray in preventing and reducing acute radiation dermatitis in patients with head and neck cancer undergoing radiotherapy.

Interventie / Behandeling |
|---|---|

Placebo-vergelijker: Placebo excipient spray
A placebo spray consisting of the excipient formulation without superoxide dismutase, which is the same as the experimental group in appearance.
|
Patients are instructed to apply a placebo excipient spray without superoxide dismutase evenly to the entire radiotherapy-treated skin area, approximately 3 sprays per application, five times daily, following the same schedule as the experimental group.
Treatment is initiated at the start of radiotherapy and continued until the occurrence of grade ≥2 radiation dermatitis or up to one week after completion of radiotherapy, whichever occurs first.
Patients are instructed to keep the irradiated skin clean and dry and to avoid the use of other topical agents in the treatment area.

Experimenteel: Superoxide dismutase containing skin spray
A topical skin spray containing superoxide dismutase
|
Patients are instructed to apply a topical superoxide dismutase-containing spray evenly to the entire radiotherapy-treated skin area, approximately 3 sprays per application, five times daily.
Treatment is initiated at the start of radiotherapy and continued until the occurrence of grade ≥2 radiation dermatitis or up to one week after completion of radiotherapy, whichever occurs first.
Patients are instructed to keep the irradiated skin clean and dry and to avoid the use of other topical agents in the treatment area.

Uitkomstmaat |
Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Incidence of grade ≥ 2 ARD
Tijdsspanne: From the start of radiotherapy to 4 weeks after completion of radiotherapy
|
Patients are assessed weekly for radiation dermatitis by an experienced radiation oncology nurse according to the Radiation Therapy Oncology Group (RTOG) scale.
The RTOG scale categorizes acute skin toxicity into grades 0-4, with the higher the grade the more severe the patient's acute radiation dermatitis.
Grade 0 means no change over baseline.
Grade 1 means follicular, faint, or dull erythema; epilation, dry desquamation, or decrease in sweating.
Grade 2 means tender, bright erythema; patchy, moist desquamation or moderate edema.
Grade 3 means confluent, moist desquamation other than skin folds; pitting edema.
Grade 4 means ulceration, hemorrhage, necrosis.

Algehele Gezondheidstoestand en Kern Dimensies van Kwaliteit van Leven
Tijdsspanne: De totale evaluatieperiode is ongeveer 14 tot 14,5 weken.
|
Europese Organisatie voor Onderzoek en Behandeling van Kanker Kwaliteit van Leven Vragenlijst Kern 30 (EORTC QLQ-C30) Dit instrument is een door patiënten gerapporteerde uitkomstmaat (PRO) met 30 items, ontworpen om kernaspecten van gezondheidsgerelateerde kwaliteit van leven bij kankerpatiënten te evalueren, inclusief 5 functionele schalen (fysiek, rol, cognitief, emotioneel, sociaal), 3 symptoomschalen (vermoeidheid, pijn, misselijkheid en braken), één globale gezondheidsstatus/kwaliteit van leven-schaal en 6 enkelvoudige symptoommetingen.
Scores worden lineair getransformeerd naar een bereik van 0-100.
Voor de functionele schalen en de globale gezondheidsstatus-schaal geven hogere scores betere functionele niveaus of kwaliteit van leven aan; voor de symptoomschalen/items geven hogere scores een grotere symptoomlast aan.

Patient-reported skin symptoms from the Skindex-16
Tijdsspanne: From 1 week before radiotherapy to 4 weeks after completion of radiotherapy.

The Skindex-16 is a commonly used tool to measure the effect of skin diseases on the skin-related QoL of patients.
Skindex-16 consists of domain scores that assess how symptoms, emotions, and functioning from the skin issue affect the QOL of patients with acne.
The overall score averages the 3 domain scores, all of which are normalized to a 0 to 100 scale, where 0 indicates that their skin condition has no impact on QOL and 100 represents maximal impact on QOL for the worse.
