Brief Summary
Radiotherapy always results in many complications such as radiation dermatitis,dry mouth, cranial nerve damage, and swallowing function. Among them,radiation dermatitis is confirmed to occur in the majority of tumor patientsreceiving radiotherapy, which not only affects the appearance but also causesthe interruption of radiotherapy in severe cases. At present, there is no standard treatment for radiation dermatitis. Superoxide dismutase (SOD) Spray is able to removefree radicals produced during radiotherapy, which may provide a new way andmethod for the prevention and treatment of radiation dermatitis. In addition,the product has obtained a safety assessment report from a third-party testingorganization, proving that it has fully met the applied human body standards. This clinical trial studies the effect of superoxide dismutase (SOD) Spray in preventing radiationdermatitis in Head and Neck Cancer.

Outcome Measures
Primary Outcomes (1)
The incidence of grade 2 or higher radiation dermatitis.
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.
From the start of radiotherapy to 4 weeks after completion of radiotherapy
Secondary Outcomes (7)
The time to onset of grade 2 or higher radiation dermatitis.
From the start of radiotherapy to 4 weeks after completion of radiotherapy
The duration of grade 2 or higher radiation dermatitis.
From the start of radiotherapy to 4 weeks after completion of radiotherapy.
The maximum skin toxicity.
From the start of radiotherapy to 4 weeks after completion of radiotherapy.
The Skindex-16 instrument.
From 1 week before radiotherapy to 4 weeks after completion of radiotherapy.
EORTC QLQ-C30.
From 1 week before radiotherapy to 4 weeks after completion of radiotherapy.

Study Arms (2)
A placebo spray
PLACEBO COMPARATORA placebo spray containing excipients (lactose, potassium sorbate, and sorbitol) in addition to no SOD.
Superoxide dismutase (SOD) Spray
EXPERIMENTALInterventions
Patients are instructed to apply the placebo spray to the treatment area twice daily, starting three days before radiotherapy (RT) and continuing until two weeks after treatment completion. The spray should be used to cover the entire treatment area. Patients are also advised not to use the spray within four hours before RT. They are required to keep the skin in the radiotherapy area dry and clean and to refrain from using other topical agents in the irradiated area. Use of the spray should be discontinued if dermatitis of grade 2 or higher occurs.
Patients are instructed to apply a thin layer of SOD spray to the treatment area twice daily, beginning three days before radiotherapy (RT) and continuing- Page 3 of 6 Arms Assigned Interventions until two weeks after treatment completion. The application should cover the entire treatment area. Patients are also advised not to use the spray within four hours before RT to avoid potential buildup effects. They are required to keep the skin in the radiotherapy area dry and clean and to refrain from using other topical agents in the irradiated area. Use of the spray should be discontinued if dermatitis of grade 2 or higher occurs.
