Special Issue Information

Dear Colleagues,

Oral cancer is the sixth most common cancer worldwide. It is frequently diagnosed in advanced stages and is associated with poor prognosis and a high mortality rate. Patients with locally advanced disease are often treated with a combination of surgery, radiotherapy, and chemotherapy, but this treatment is still controversial due to its high morbidity and mortality rate. Despite the development of multimodal therapeutic strategies, most cases develop recurrences at local and/or regional level and about a third develop distant metastasis. Therefore, it is necessary to know the molecular mechanisms underlying resistance to chemotherapy, which will allow the development of new more effective therapeutic strategies in the treatment of oral cancer. It is known that the molecular profiles of tumors are heterogeneous and dynamic during the course of the disease and treatment. The cellular mosaicism is related to therapy resistance and the ability to metastasize the different subpopulations of cancer cells, which is key for development targets and personalized therapy. The aim of this Special Issue is to gather the recent advances on clinically potential biomarkers to apply a precision oncology in the field of oral cancer. On behalf of the Journal of Clinical Medicine, we are inviting relevant original research, reviews, and short communications related to this topic.

Oral carcinogenesis is a multistep process characterized by a summation of multiple genetic and epigenetic alterations in key regulatory genes. The silencing of genes by aberrant promoter hypermethylation is thought to be an important epigenetic event in cancer development and progression which has great potential as a biomarker for early diagnosis, tumor molecular subtyping, prognosis, monitoring, and therapy. Aberrant DNA methylation has been detected in different liquid biopsies, which may represent a potential alternative to solid biopsies. The detection of methylated genes in saliva may have clinical application for noninvasive oral cancer screening and early diagnosis. Here, we review the current evidence on gene promoter hypermethylation in saliva. Full article

Fast, economic, and noninvasive, molecular analysis of saliva has the potential to become a diagnostic tool of reference for several local and systemic diseases, oral cancer included. The diagnosis of Oral Squamous Cell Carcinoma (OSCC) can be performed using high specificity and sensibility biomarkers that can be encountered in the biological fluids. Recent advances in salivary proteomics have underlined the potential use of salivary biomarkers as early diagnosis screening tools for oral neoplasia. In this respect, over 100 salivary molecules have been described and proposed as oral cancer biomarkers, out of which cytokines are among the most promising. Besides being directly involved in inflammation and immune response, the role of salivary cytokines in tumor growth and progression linked them to the incidence of oral malignant lesions. This review summarizes the existing studies based on the use of salivary cytokines as potential oral cancer biomarkers, their involvement in the malignant process based on their type, and ther influence upon prognostic and metastatic rates.
