Hypothesis
The worse prognosis of head and neck squamous cell carcinomas (HNSCCs) is linked to their influence on the host immune system.
Conclusion
HNSCCs significantly compromise antitumor immune responses due to various immune evasion mechanisms.
Supporting Evidence
- HNSCCs are the sixth most common cancer worldwide.
- Despite treatment advances, the 5-year survival rate for HNSCCs remains below 50%.
- Functional defects in T-cells are common in HNSCC patients.
- Langerhans cells are increased in benign tumors but decreased in invasive carcinomas.
- Macrophages in peritumoral areas play a crucial role in tumor progression.
Takeaway
Head and neck cancers can trick the body's immune system, making it harder for the body to fight the cancer. This is why these cancers can be very dangerous.
Methodology
The review summarizes various studies on immune suppression mechanisms in HNSCCs, including the role of T-cells, macrophages, and dendritic cells.
Limitations
The review is based on existing literature and may not include all recent findings.
Participant Demographics
The review discusses findings from various studies involving patients with head and neck cancers, but specific demographics are not detailed.
