Special Issue Information
Dear Colleagues,
Oral squamous cell carcinoma (OSCC), the most prevalent malignancy of the oral cavity, continues to present significant clinical challenges due to its frequent resistance to standard-of-care treatments such as chemotherapy, radiotherapy, and immunotherapy. Despite advances in molecular diagnostics and treatment modalities, therapeutic resistance remains a major barrier in achieving durable responses and improved survival in OSCC patients.
Resistance to therapy is a multifaceted process driven by tumor-intrinsic alterations (e.g., genetic mutations, epigenetic changes, and metabolic reprogramming) and tumor-extrinsic factors (e.g., immunosuppressive tumor microenvironments and stromal remodeling). The emergence of resistant subclones, impaired drug delivery, and immunotherapy evasion mechanisms further exacerbates disease progression and recurrence.
To address this pressing issue, there is a growing need to achieve the following:
- Decipher the molecular and cellular mechanisms underlying therapeutic resistance;
- Identify robust predictive biomarkers to stratify responders from non-responders; and
- Develop novel therapeutic agents or combination strategies to overcome resistance and restore treatment sensitivity.
For this Special Issue of Biomedicines, entitled “Therapeutic Resistance in Oral Cancer: Mechanisms, Biomarkers, and Novel Strategies to Restore Treatment Responses”, we welcome submissions that explore the following:
- Mechanistic insights into chemoresistance, radioresistance, or immunotherapy resistance in OSCC;
- Novel biomarkers predictive of treatment responses or resistance;
- Preclinical and clinical studies on drug repurposing or novel agents targeting resistant OSCC;
- Combination strategies designed to enhance responses to standard-of-care therapies;
- Tumor microenvironment and immune landscape alterations contributing to resistance;
- Systems biology and omics-based approaches to predicting or monitoring treatment outcomes.
Original research articles, reviews, systematic reviews, and meta-analyses are all welcome. Submissions focusing on translational aspects and therapeutic innovations in OSCC and HNSCC are especially encouraged.
We look forward to receiving your valuable contributions to advance our understanding and treatment of therapeutic resistance in oral cancer.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. 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 short 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. Biomedicines is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
