Special Issue Information

Dear Colleagues,

This Special Issue in the journal Cancers is dedicated to the in-depth exploration of oral potentially malignant disorders (OPMDs) and oral cavity cancer, focusing on clinical, molecular, and translational aspects. We invite contributions from experts in the field, covering topics such as the clinical characteristics, pathology, molecular biology, and genomics of OPMDs. This Special Issue emphasizes key events in the transition of OPMDs to oral cavity cancer, with a particular focus on gene variations, protein abnormalities, and cellular signaling pathways associated with pathogenesis. Additionally, we welcome research on novel diagnostic tools, imaging techniques, and therapeutic strategies to enhance the precision of early detection and treatment. This Special Issue seeks contributions that provide new insights and approaches to the treatment of OPMDs and oral cavity cancer, including advancements in personalized therapy, immunotherapy, and targeted treatments. Ultimately, we aim to advance a more comprehensive and in-depth understanding of these disorders, fostering translational medicine and precision healthcare in clinical practice.

In this Special Issue, we enthusiastically invite the submission of original research articles and reviews. We welcome contributions across a broad spectrum of research areas, including but not limited to the following:

  • Clinical characteristics of oral potentially malignant disorders (OPMDs);
  • Molecular mechanisms underlying the progression of OPMDs to oral cavity cancer;
  • Advances in diagnostic imaging technologies for early detection;
  • Biomarkers for predicting the risk and progression of oral cavity cancer;
  • Therapeutic approaches and novel interventions for OPMDs and oral cavity cancer;
  • Genomic and proteomic studies informing precision medicine in oral oncology;
  • Immunotherapeutic strategies and immune microenvironment in oral cavity tumors;

Background: Chronic periodontitis, an inflammation-related disorder affecting global populations, has been revealed to be linked to diverse cancers. Numerous epidemiological studies have not shown a link between chronic periodontitis and blood cancers in Taiwan. Methods: This study included 601,628 patients, diagnosed with newly chronic periodontitis by the ICD-9-CM classification, who were enrolled from 2001 to 2021 in the National Health Insurance Research Database (NHIRD) in Taiwan. In this study, we employed comprehensive statistical analyses to investigate the association between chronic periodontitis and hematologic cancers. Initially, we calculated incidence density and used a Poisson regression to analyze relative risk. Subsequently, we compared the cumulative incidence of hematological cancer in both chronic and non-chronic periodontitis groups using the Kaplan–Meier method. Results: The results revealed a significantly lower cumulative incidence of hematologic cancer in individuals with non-chronic periodontitis over a 12-year follow-up period. To further explore the risk factors, a Cox proportional hazard regression analysis was conducted. Being male (adjusted hazard ratio [aHR] = 1.21, 95% CI: 1.04 to 1.42; p = 0.014) and having hypertension (aHR = 1.34, 95% CI: 1.06 to 1.69; p = 0.015) were demonstrated to be associated with an increased risk of hematologic cancers, respectively. In addition, in a subtype multivariate analysis for categorizing hematologic cancers into lymphoma and leukemia, the aHR for leukemia was 1.48 (95% CI: 1.13 to 1.93; p = 0.004) and aHR for lymphoma was 1.15 (95% CI: 0.96 to 1.37; p = 0.140). Conclusions: This study found that being male and having hypertension were the significant risk factors for hematological malignancies. Moreover, the association between chronic periodontitis and specific subtypes of hematologic cancers was confirmed. Full article

Oral cancer, particularly oral squamous cell carcinoma (OSCC), is a significant global health challenge because of its high incidence and limited treatment options. Major risk factors, including tobacco use, alcohol consumption, and specific microbiota, contribute to the disease’s prevalence. Recently, a compelling association between diabetes mellitus (DM) and oral cancer has been identified, with metformin, a widely used antidiabetic drug, emerging as a potential therapeutic agent across various cancers, including OSCC. This review explores both preclinical and clinical studies to understand the mechanisms by which metformin may exert its anticancer effects, such as inhibiting cancer cell proliferation, inducing apoptosis, and enhancing the efficacy of existing treatments. Preclinical studies demonstrate that metformin modulates crucial metabolic pathways, reduces inflammation, and impacts cellular proliferation, thereby potentially lowering cancer risk and improving patient outcomes. Additionally, metformin’s ability to reverse epithelial-to-mesenchymal transition (EMT), regulate the LIN28/let-7 axis, and its therapeutic role in head and neck squamous cell carcinoma (HNSCC) are examined through experimental models. In clinical contexts, metformin shows promise in enhancing therapeutic outcomes and reducing recurrence rates, although challenges such as drug interactions, complex dosing regimens, and risks such as vitamin B12 deficiency remain. Future research should focus on optimizing metformin’s application, investigating its synergistic effects with other therapies, and conducting rigorous clinical trials to validate its efficacy in OSCC treatment. This dual exploration underscores metformin’s potential to play a transformative role in both diabetes management and cancer care, potentially revolutionizing oral cancer treatment strategies.
