Comment on, "Characterization of oral microbiota in HPV and non-HPV head and neck squamous cell carcinoma and its association with patient outcomes".

The article "Characterization of oral microbiota in HPV and non-HPV head and neck squamous cell carcinoma and its association with patient outcomes" by Chan et al. investigates the relationship between oral microbiota, HPV infection, and patient outcomes in head and neck squamous cell carcinoma (HNSCC). This comprehensive study, involving 166 Chinese adults, utilized advanced sequencing techniques to profile bacterial and HPV regions in paired tumor and control tissues. The findings highlight the complex interplay between microbiota dysbiosis, HPV infection, and HNSCC progression. Despite the robustness of the study, limitations include potential biases in DNA extraction and PCR amplification, and unaccounted environmental factors. Recommendations for future research include increasing sequencing depth, comparing DNA extraction methods, using multiple bioinformatics pipelines, and controlling for environmental variables. Longitudinal studies and microbiota-targeted interventions are suggested to further elucidate the role of oral microbiota in HNSCC and improve patient outcomes.
