Background

High-throughput technologies have produced vast multi-omics datasets (genomics, transcriptomics, epigenomics, proteomics) from large cancer initiatives such as The Cancer Genome Atlas (TCGA) and the Clinical Proteomic Tumor Analysis Consortium (CPTAC). These resources offer great potential, but a key challenge remains finding biomarkers that accurately diagnose, prognosticate, or predict therapeutic response in diverse cancers, with robust and reproducible results. Many biomarkers identify only a single type of cancer, which limits their broader clinical use. Integrating different omics layers to reveal complex, system-level biomarkers require advanced computational approaches that manage high dimensionality, noise, and biological heterogeneity. This Research Topic seeks studies on new computational and statistical methods for discovering and validating next-generation, pan-cancer biomarkers, with an emphasis on integrative models over single-omics analyses.

The primary goal of this Research Topic is to spotlight innovative computational approaches that advance cancer mutation and biomarker discovery. We seek methods that enhance sensitivity, specificity, and clinical utility by leveraging integrated multi-omics data. We are particularly interested in contributions that address the challenges of pan-cancer analysis, aiming to identify biomarkers and biological pathways that are conserved across multiple cancer types, which could lead to more universal diagnostic tools or therapeutic strategies.
The scope of this topic includes, but is not limited to, the following themes:
• Novel AI/ML Models: Development of deep learning, graph neural networks, or other machine learning frameworks for multi-omics data fusion and feature selection.
• Network-Based Approaches: Algorithms that leverage biological networks to identify robust, pathway-level biomarkers with strong functional implications.
• Liquid Biopsy and Minimally Invasive Biomarkers: Computational methods for analyzing circulating tumor DNA (ctDNA), exosomes, or other liquid biopsy data for early detection and monitoring.
• Spatial Transcriptomics/Proteomics Integration: Develop computational tools that add spatial context to biomarker discovery. These tools should enable the linking of molecular profiles to the structure of the tumor microenvironment.
• Robustness and Reproducibility: Studies focusing on the validation of computational pipelines across independent cohorts and their application to real-world clinical data.
• Explainable AI in Biomarker Discovery: Methods that provide biological interpretation for predictions made by complex models, building trust for clinical adoption.

We welcome Original Research, reviews, mini-reviews, Systematic Reviews, Perspectives, Methods, hypotheses and theories, Clinical Trials, Technology and Code, Study Protocols, Brief Research Reports, Data Reports, General Commentaries, and Opinion papers that link genetic mutations and clinical biomarkers for solid tumors and blood cancers.

Topic editors

Frequently asked questions

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

     

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

  • Yes, we would love to hear your ideas for a topic. Most of our Research Topics are community-led and suggested by researchers in the field. Our in-house editorial team will contact you to talk about your idea and whether you’d like to edit the topic. If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

     

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

  • As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

  • If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor. This provides you with valuable editorial experience, improving your ability to critically evaluate research articles and enhancing your understanding of the quality standards and requirements for scientific publishing, as well as the opportunity to discover new research in your field, and expand your professional network.

  • Yes, certificates can be issued on request. We are happy to provide a certificate for your contribution to editing a successful Research Topic.
