Background

Over the past fifty years, median cancer survival rates have markedly improved, largely due to advances in therapies targeting the immune system. Among these transformative approaches, cancer immunotherapy stands out for enabling more personalized, less toxic treatments and conferring long-term protective benefits, even enabling the development of cancer vaccines. Despite such progress, significant challenges persist. Certain cancer types remain resistant to current immunotherapeutic interventions, and much remains to be learned about mechanisms of response, resistance, and effective translation into clinical practice.

This Research Topic invites contributions that span the full spectrum of cancer immunology, from basic science to post-marketing outcomes. We encourage original research articles, reviews, systematic reviews, and perspectives that delve into innovative advances and persistent barriers in cancer immunotherapy. Authors are especially encouraged to submit work reporting negative, inconclusive, or unexpected results, as sharing such findings can prevent redundant research and accelerate progress.

The main challenge in cancer immunotherapy is the variable and sometimes limited effectiveness against certain cancer types, as well as the continual emergence of resistance and toxicities. Addressing these gaps requires a comprehensive investigation of underlying immune mechanisms, innovative therapeutic strategies, and real-world clinical experiences, including those that do not yield positive outcomes. By spotlighting both successes and setbacks, this Research Topic aims to foster a nuanced understanding of the immunological landscape of cancer and to promote the identification of new targets, biomarkers, and combination strategies. Our goal is to catalyse interdisciplinary dialogue and accelerate the translation of research findings into meaningful clinical applications that improve patient outcomes across diverse cancer types.

Cancer immunotherapy has rapidly evolved from a conceptual approach to a central pillar of oncology treatment. Therapies such as immune checkpoint inhibitors, adoptive cell therapies, and cancer vaccines have revolutionized outcomes for certain malignancies. Moreover, combination therapies leveraging immune modulation alongside chemotherapy, targeted agents, or novel technologies are demonstrating promise in overcoming resistance and enhancing efficacy. Yet, for a subset of cancers, durable responses remain elusive, and immune-related adverse events pose ongoing challenges. As the field advances, exploring the breadth of immunotherapeutic strategies—including innovative delivery platforms, new immune targets, and modes of overcoming resistance—is crucial for broadening the benefits of immunotherapy to a wider patient population.

This Research Topic welcomes submissions covering all aspects of cancer immunology and immunotherapy, from fundamental studies to clinical data and translational research. We seek manuscripts addressing, but not limited to:
• Adoptive cell therapies (CAR-T, TCR, TIL, NK)
• Cancer vaccination strategies (cell-, peptide-, nucleotide-, virus-based; mRNA, viral delivery)
• Clinical trials and translational research (including reports of negative results)
• Combination therapies, either synergistic or antagonistic
• Cytokine therapy and modulation of the tumor microenvironment
• Mechanisms of resistance and strategies for resensitization
• Novel directions and technology platforms (e.g., nanoparticles)
• Immune checkpoint inhibition (e.g., PD-1, PD-L1, CTLA-4, LAG-3)
• Monoclonal, bispecific, and antibody-drug conjugates
• Oncolytic virus-based therapies (viral delivery, cargo design, immune responses)
• Safety and toxicology (in vivo animal work; clinical trials, any phase)

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.
