To elucidate the role of the microbiome, inflammation, and immunity in the pathogenesis of oral squamous cell carcinoma (OSCC) and to propose a conceptual framework for understanding these interactions, highlighting its significance in advancing research and treatment strategies.
Key Findings:
Oral squamous cell carcinoma accounts for approximately 90% of oral cancers, underscoring the need for targeted research.
Chronic inflammation, such as that caused by periodontitis, contributes to OSCC progression through sustained release of pro-inflammatory cytokines and immune dysregulation, indicating potential therapeutic targets.
Dysbiosis of the oral microbiota is strongly associated with OSCC development, with specific microorganisms promoting carcinogenesis, suggesting avenues for microbiome-based interventions.
Microbiota transplantation studies indicate that microbial composition can influence tumorigenesis, highlighting the potential for novel treatment strategies.
Interpretation:
The proposed microbiome-inflammation-immune axis offers a novel perspective on the interactions between oral microbiota, inflammation, and immune responses in the context of OSCC, emphasizing the need for integrated research approaches that could transform clinical practice.
Limitations:
The complex interactions among microbiota, inflammation, and immunity are not fully understood, particularly regarding their mechanistic links.
Current research often focuses on isolated pathways rather than the interconnectedness of these factors, such as specific cytokine signaling pathways.
Conclusion:
The review emphasizes the importance of understanding the microbiome's role in OSCC and suggests that clinical indicators from inflammation and microbiology could aid in future diagnosis and treatment, calling for further research to explore these connections.
