Changes in oral microbial profiles associated with oral squamous cell carcinoma vs leukoplakia
Aim
Oral squamous cell carcinoma (OSCC) is the most frequently occurring cancer among head and neck SCC worldwide. The identification of novel effective biomarkers for early detection may greatly improve the survival rate and prognosis of patients with OSCC. This study aimed to identify specific oral microbial profiles associated with OSCC.
Methods
Saliva samples were collected from oral leukoplakia (OLK) and OSCC patients (N = 6 each) and healthy controls (HC; N = 4). Total bacterial genomic DNA was isolated and 16S rRNA gene survey was performed by next-generation sequencing of the V4 region. The relative distribution of abundance for phylogenetic groups was compared among the OSCC and OLK groups.
Results
The 448 operational taxonomic units detected from the libraries were classified into 133 genera, 69 families, 41 orders, 26 classes and 12 phyla. The abundance of phyla Bacteroidetes and genus Solobacterium was notably higher in the OSCC group when compared with the OLK group, whereas those of genus Streptococcus was significantly lower in the OSCC group when compared with the OLK.
Conclusion
These changes in the salivary microbiome may have potential applications as a novel diagnostic tool for the early detection of OSCC.
期刊介绍：
Journal of Investigative and Clinical Dentistry (JICD) aims to publish quality, peer reviewed original research and topical reviews on all aspects of investigative and clinical dentistry and craniofacial research, including molecular studies related to oral health and disease. Although international in outlook, the Editor especially encourages papers from the Asia Pacific. The journal also aims to provide clinicians, scientists and students of dentistry with a knowledge transfer platform for rapid publication of reports through an international journal, which will be available free online until 2012. Its scope, therefore, is broad, inclusive and international, but with a particular focus on Asia Pacific. The Editor welcomes manuscripts in the following key thematic areas in oral and maxillofacial sciences: Community Dentistry and Oral Epidemiology, Conservative Dentistry, Dental Biomaterials, Dental Pedagogy, Endodontics and Traumatology, Implant Dentistry, Oral Biosciences, Oral and Maxillofacial Surgery, Oral Medicine, Oral Pathology and Oral Microbiology, Orthodontics, Oral Radiology, Oral Rehabilitation, Paedodontics, Periodontology and Periodontal Medicine.
