Recent Advances in Head and Neck Tumor Microenvironment-Based Therapy.

Area of Science:

• Oncology
• Cancer Biology
• Tumor Microenvironment Research

Background:

• Head and neck squamous cell carcinomas (HNSCCs) are aggressive tumors with poor survival rates.
• While tobacco- and alcohol-related HNSCCs decrease, human papillomavirus (HPV)-induced HNSCCs are rising.
• Current treatments combined with chemoradiation therapy (CRT) show limited efficacy due to resistance.

Purpose of the Study:

• To review recent advances in understanding the HNSCC tumor microenvironment (TME).
• To highlight novel cell-cell interactions within the HNSCC TME.
• To discuss emerging therapies targeting the HNSCC TME.

Main Methods:

• Literature review of recent studies on HNSCC tumor microenvironment.
• Analysis of cell-cell interactions within the TME.
• Summary of novel therapeutic strategies under development.

Main Results:

• The HNSCC TME comprises various cells (e.g., CAFs, immune cells) and extracellular matrix (ECM) components.
• Tumor microenvironment plays a significant role in HNSCC progression and resistance to therapy.
• Emerging therapies focus on targeting TME components and interactions.

Conclusions:

• Understanding TME crosstalk with cancer cells is essential for improving HNSCC treatment outcomes.
• Targeting the TME offers promising avenues for overcoming CRT resistance in HNSCC.
• Novel therapeutic strategies are being developed to exploit TME vulnerabilities in HNSCC.
