There is no standard treatment for radiation dermatitis. In this study, the investigators have designed novel ROS-scavenging nanoenzymes and aim to evaluate their effectiveness in preventing radiation dermatitis in patients with head and neck cancer.

Radiotherapy often leads to various complications, with radiation dermatitis being the most common side effect observed in the majority of tumor patients undergoing treatment. This condition not only affects a patient's appearance but, in severe cases, may even require the interruption of treatment.

Currently, there is no standard treatment for radiation dermatitis. In this study, the investigators have designed novel ROS-scavenging nanoenzymes, offering a potential new approach for preventing and treating radiation dermatitis.

This clinical trial aims to evaluate the effectiveness of these novel ROS-scavenging nanoenzymes in preventing radiation dermatitis in patients with head and neck cancer.

Inclusion Criteria:

1. Patients with a pathological diagnosis of non-metastatic head and neck malignant tumors;
2. Patients deemed suitable for high-dose radiotherapy, either as a primary treatment or as postoperative treatment following surgical resection.

Exclusion Criteria:

1. Eastern Cooperative Oncology Group performance status of >2;
2. Pre-existing skin rash, ulceration or open wound in the treatment area;
3. Inflammatory or connective tissue disorder of the skin;
4. History of head and neck radiotherapy.
