About this Research Topic

Background

Oral and oropharyngeal cancers pose a significant health burden worldwide, necessitating a deeper understanding of the underlying mechanisms driving tumor progression. The role of immune cells in the context of these malignancies has garnered considerable attention in recent years. Immune cells play a pivotal role in shaping the tumor microenvironment and influencing cancer progression.

Various immune cell populations, including T cells, B cells, natural killer cells, myeloid-derived suppressor cells, and dendritic cells, contribute to the complex interplay between the immune system and oral and oropharyngeal cancers. These immune cells can exhibit both pro-tumorigenic and anti-tumorigenic functions, depending on their phenotypes, activation status, and spatial distribution within the tumor microenvironment. Dysregulation of immune cell functions can lead to immune evasion, tumor immune tolerance, and metastasis.

Understanding the dynamic interactions between immune cells and cancer cells is crucial for developing effective immunotherapeutic strategies. Targeting specific immune cell subsets or modulating their activity holds promise for enhancing anti-tumor immune responses and improving treatment outcomes. Additionally, immune cell-based biomarkers may provide valuable prognostic and predictive information for personalized therapeutic approaches.

The problem that we aim to address in this Research Topic is the limited understanding of the intricate interactions between immune cells and the tumor microenvironment in these types of cancers. Despite advancements in cancer immunotherapy, the specific mechanisms by which immune cells influence tumor progression, immune evasion, and treatment response in oral and oropharyngeal cancers remain incompletely understood.

To achieve a better understanding of these complex dynamics, several approaches can be taken. Firstly, comprehensive studies are needed to characterize the phenotypic and functional profiles of different immune cell subsets within the tumor microenvironment. This can be achieved through high-dimensional analyses such as single-cell sequencing, flow cytometry, and multiplex immunohistochemistry.

Secondly, investigating the crosstalk between immune cells and tumor cells, as well as the signaling pathways involved, will provide insights into the mechanisms of immune evasion and resistance to therapy. This can be accomplished through in vitro co-culture systems and animal models that recapitulate the tumor microenvironment.

Furthermore, identifying predictive biomarkers of treatment response and understanding the mechanisms of immune resistance are essential. Recent advances in genomic profiling, including next-generation sequencing and multi-omics approaches, can aid in identifying potential biomarkers and therapeutic targets.

Lastly, recent advances in immunotherapeutic strategies, such as immune checkpoint inhibitors, CAR-T cell therapy, and personalized cancer vaccines, hold promise for enhancing anti-tumor immune responses in oral and oropharyngeal cancers. Further investigation into the efficacy and mechanisms of these therapies in the context of immune cell interactions is warranted.

By addressing these research gaps and leveraging recent advances, we can deepen our understanding of the role of immune cells in oral and oropharyngeal cancer progression. This knowledge will contribute to the development of more effective immunotherapies, personalized treatment approaches, and improved outcomes for patients with these challenging malignancies.

We encourage authors to explore various aspects related to immune cells and their impact on these malignancies. Specific themes that can be addressed in the submitted articles include, but are not limited to:

1. Immune cell populations in the tumor microenvironment: Investigating the composition and dynamics of immune cell subsets within the oral and oropharyngeal tumor microenvironment, including their roles in promoting or inhibiting tumor growth and metastasis.

2. Immune evasion mechanisms employed by tumor cells and their interaction with immune cells.

3. Tumor microenvironment and its influence on immune cell infiltration and activation.

4. Immunotherapeutic approaches: Assessing the efficacy of immunotherapies, such as immune checkpoint inhibitors, adoptive cell therapies, and cancer vaccines, in enhancing anti-tumor immune responses and improving treatment outcomes.

5. Immune biomarkers for prognosis, prediction of treatment response, and patient stratification.

6. Interplay between the microbiome, immune cells, and tumor progression in the oral and oropharyngeal regions.

7. Combination therapies: Exploring the potential of combining immunotherapies with conventional treatments, such as chemotherapy and radiation therapy, to enhance immune cell-mediated tumor control.

We welcome original research articles, reviews, and perspectives that shed light on these themes and contribute to our understanding of the complex immune landscape in oral and oropharyngeal cancer progression. By addressing these topics, we aim to advance the field and ultimately improve patient care and outcomes in this challenging field.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
