NCT07086638

Brief Summary

Severe radiation dermatitis remains a challenging complication in head and neck cancer with limited treatment options; this study aims to evaluate a novel Prussian blue-based nanozyme combined with near-infrared thermotherapy to promote effective healing of Grade III lesions.

Conditions

Outcome Measures

Primary Outcomes (1)

  • The incidence of grade 3 radiation dermatitis

    Patients are assessed weekly for radiation dermatitis by an experienced radiation oncology nurse according to the Radiation Therapy Oncology Group (RTOG) criteria.

    From the onset of Grade III dermatitis to two weeks after the completion of radiotherapy

Secondary Outcomes (1)

  • Bacterial load at the site of dermatitis

    From the first administration of drug treatment through study completion, an average of 1 month.

Study Arms (1)

Photo-responsive nanozyme

EXPERIMENTAL

The nanozyme scavenges ROS at the site of dermatitis and simultaneously responds to NIR light to generate mild heat, thereby promoting the healing of radiation-induced skin injury.

Drug: Photo-responsive nanozyme

Interventions

The nanozyme scavenges ROS at the site of dermatitis and simultaneously responds to NIR light to generate mild heat, thereby promoting the healing of radiation-induced skin injury.

Photo-responsive nanozyme
