Brief summary: Evaluation of the safety and tolerability of immune-targeted therapy combined with neoadjuvant therapy with lysogenic HSV virus for patients with surgically resectable squamous carcinoma of the head and neck.

Detailed description: Head and Neck Squamous Cell Carcinoma (HNSCC) is one of the most common malignant tumors in the head and neck region. Globally, both its incidence and mortality rates have shown a significant upward trend, posing a serious threat to the life and health of patients.

Although surgical resection is the main treatment approach for resectable HNSCC, a considerable number of patients still face a high risk of local recurrence and distant metastasis after surgery, which are the key factors contributing to poor prognosis.

In recent years, immune-targeted therapy has emerged in the field of malignant tumor treatment and demonstrated unique treatment advantages and potential. It can specifically act on relevant targets of tumor cells, precisely regulate the body's immune system, and effectively enhance the body's immune response to tumor cells, thereby inhibiting the malignant biological behaviors of tumor cells such as growth, proliferation, and metastasis. Oncolytic herpes simplex virus (HSV) has the ability to specifically replicate within tumor cells and lyse them. Meanwhile, it can also induce a strong anti-tumor immune response in the body and has broad application prospects in tumor treatment.

Based on the above situation, this study innovatively proposes to combine immune-targeted therapy with oncolytic HSV virus for the neoadjuvant treatment of resectable HNSCC. The aim is to fully utilize the synergistic effect of the two treatment modalities, minimize the tumor volume to the greatest extent, reduce the tumor stage, improve the surgical resection rate and radicality, decrease the risks of postoperative recurrence and metastasis, and ultimately improve the quality of life and prognosis of patients. By conducting this prospective, single-arm clinical study, it is expected to provide a more efficient, safe, and innovative treatment strategy and clinical practice basis for the treatment of resectable HNSCC.
