Robotic Surgery for Head and Neck Tumors: What are the Current Applications?

BACKGROUND

The journey from radical treatments to the precision of robotic surgery underscores a commitment to innovation and patient-centered care in the field of head and neck oncology.

PURPOSE OF REVIEW

This article provides a comprehensive overview that not only informs but also stimulates ongoing discourse and investigation into the optimization of patient care through robotic surgery. The literature on current robotic applications within head and neck region was systematically reviewed.

RECENT FINDINGS

Thirty-four studies with a total of 1835 patients undergoing robotic surgery in head and neck region were included. Clinical staging, histological types, operative duration, postoperative complications, functional recovery and survival outcomes were compared and evaluated. Clinical outcomes have shown promising results and thus the indication on the robotic usage has no longer been limited to oropharyngeal region but from skull base to neck dissection. The latest advancement in robotic surgery further refines the capabilities of surgeons into previously difficult-to-access head and neck regions and heralds a new era of surgical treatment for head and neck oncology.

The Use of Immune Regulation in Treating Head and Neck Squamous Cell Carcinoma (HNSCC)

Immunotherapy has emerged as a promising new treatment modality for head and neck cancer, offering the potential for targeted and effective cancer management. Squamous cell carcinomas pose significant challenges due to their aggressive nature and limited treatment options. Conventional therapies such as surgery, radiation, and chemotherapy often have limited success rates and can have significant side effects. Immunotherapy harnesses the power of the immune system to recognize and eliminate cancer cells, and thus represents a novel approach with the potential to improve patient outcomes. In the management of head and neck squamous cell carcinoma (HNSCC), important contributions are made by immunotherapies, including adaptive cell therapy (ACT) and immune checkpoint inhibitor therapy. In this review, we are focusing on the latter. Immune checkpoint inhibitors target proteins such as programmed cell death protein 1 (PD-1) and cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) to enhance the immune response against cancer cells. The CTLA-4 inhibitors, such as ipilimumab and tremelimumab, have been approved for early-stage clinical trials and have shown promising outcomes in terms of tumor regression and durable responses in patients with advanced HNSCC. Thus, immune checkpoint inhibitor therapy holds promise in overcoming the limitations of conventional therapies. However, further research is needed to optimize treatment regimens, identify predictive biomarkers, and overcome potential resistance mechanisms. With ongoing advancements in immunotherapy, the future holds great potential for transforming the landscape of oral tumor treatment and providing new hope for patients.
