๐ Background
Cancer remains a pressing global health issue, with rising incidence and mortality rates. Traditional risk factors such as tobacco use and genetic predisposition have long been recognized, but recent studies are uncovering the critical role of the oral microbiota in cancer development. This evolving understanding opens new avenues for research and potential therapeutic strategies.
๐๏ธ Study
The review conducted by Liang et al. focuses on the intricate relationship between the oral microbiota and various cancers, including oral squamous cell carcinoma, esophageal adenocarcinoma, and pancreatic ductal adenocarcinoma. The authors summarize recent findings that illustrate how specific pathogenic bacteria contribute to tumor progression through mechanisms such as chronic inflammation and immune evasion.
๐ Results
The findings indicate that bacteria like Porphyromonas gingivalis and Fusobacterium nucleatum are implicated in promoting cancer. The dysbiosis of the oral microbiota, often exacerbated by lifestyle choices, further enhances these carcinogenic processes. Additionally, the review highlights the potential of saliva-based microbial biomarkers for non-invasive cancer screening, which could revolutionize early detection methods.
๐ Impact and Implications
The implications of this research are profound. By understanding the oral microbiota’s role in cancer, we can develop targeted therapies and early detection strategies that could significantly reduce the global cancer burden. The integration of multi-omics technologies and artificial intelligence in precision oncology is paving the way for more personalized and effective treatment options.
๐ฎ Conclusion
This review underscores the transformative potential of microbial research in oncology. By focusing on the oral microbiota, we can enhance our understanding of cancer mechanisms and develop innovative strategies for early detection and treatment. The future of cancer research is bright, and we encourage continued exploration in this promising field!

Abstract
Cancer remains a major global health concern, with escalating incidence and mortality rates underscoring the urgent need for novel diagnostic and therapeutic strategies. Increasing evidence has identified the oral microbiota as a critical contributor to tumorigenesis, thereby expanding the understanding of cancer pathogenesis beyond conventional risk factors such as tobacco use and genetic predisposition. This review summarizes recent progress in elucidating the complex relationship between the oral microbiota and various malignancies, particularly oral squamous cell carcinoma, esophageal adenocarcinoma, and pancreatic ductal adenocarcinoma. Pathogenic bacteria, including Porphyromonas gingivalis and Fusobacterium nucleatum, have been implicated in promoting tumor progression through mechanisms involving chronic inflammation, the production of metabolic toxins, and immune evasion. The dysbiosis of the oral microbiota, often driven by lifestyle factors such as poor diet, tobacco use, and alcohol consumption, further exacerbates these carcinogenic processes. Emerging therapeutic approaches including probiotics, oral microbiota transplantation, and CRISPR-based bacterial editing are under investigation for their potential to restore microbial homeostasis and suppress pathogenic species. Additionally, saliva-based microbial biomarkers have shown promise for non-invasive cancer screening. The integration of multi-omics technologies and artificial intelligence-driven platforms is further advancing the development of precision oncology. This review aims to consolidate fragmented findings concerning the oral microbiota-cancer axis and address existing gaps in mechanistic understanding. The review’s significance lies in the translational potential of microbial research to clinical applications, offering opportunities to reduce the global cancer burden through early detection and microbiota-targeted therapies.
