Special Issue Information

Dear Colleagues,

In addition to the role that microbiome, dysbiosis, and specific pathogens play in infectious and autoimmune diseases, the potential influences on cancer development are also increasingly recognized. The concept of cancer associated with the microbiota is currently a hot topic, and researchers have a great deal of attention to the role of the microbiome, dysbiosis, specific pathogens, and cancer.

The oral cavity is one of the largest microbial repositories in the human body, and microbial variations in the oral cavity could be highly linked to malignancies of both the oral cavity and distant organs.

Oral dysbiosis and specific pathogens, such as Human Papillomavirus, Epstein–Barr virus, and Candida Albicans, have been associated with premalignant and malignant lesions of the oral cavity and head and neck region and have been implied in malignant transformation of the oral mucosa.

Moreover, many different species of oral bacteria, viruses, fungi, and protozoa are known to affect general health and several systemic disorders and diseases, including extra-oral cancers of the lung, esophagus, stomach, pancreas, liver, and colorectum. The oral microbiome could promote carcinogenesis at extra-oral sites either through systemic inflammation, the distant indirect effect of virulence factors, microorganisms' direct translocation via the bloodstream, the oro-digestive and respiratory tracts, or influencing responsiveness to treatments by interacting with the host immune response.

Studies from basic to clinical research, reviews and communications, exploring the inter-relation between the oral microbiome, specific pathogens, dysbiotic phenomena, and infection, and oral and extra-oral cancerogenesis, and investigating cancer prevention measures and therapeutic interventions based on reversing dysbiosis and eradicating infections are welcome.

Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cancers is an international peer-reviewed open access semimonthly journal published by MDPI.

Oral squamous cell carcinoma (OSCC) is the most common oral cavity malignancy associated with multiple risk factors. In the last 14 years, oral dysbiosis has attracted the scientific community’s attention as a potential oncogenic factor, in parallel with the development of omics technologies that have revolutionized microbiological research. The present umbrella review aimed to investigate the oral microbiological content (bacilli, viruses, and fungi) of tissue and saliva samples from adult (>18 years) patients with OSCC. The secondary objective was to compare the oral microbiome of OSCC subjects with non-OSCC subjects. The study protocol was under the PRISMA statement and registered on PROSPERO (CRD42023448153). Data from 32 systematic reviews were extracted, qualitatively summarized, and analyzed using AMSTAR-2. An increase in oral bacteria of the phylum Fusobacteria, Proteobacteria, and Bacteroidetes and a decrease in Firmicutes and Actinobacteria were observed in OSCC patients. The increased bacterial genera were periodontopathogens. The most common viruses were EBV and HPV, especially the high-risk genotypes. Candida was the most studied oral fungus and was always increased in OSCC subjects. Further studies should investigate the possible carcinogenic mechanisms of oral microorganisms found increased in tissue samples and saliva from adult subjects with OSCC. Full article
