Background

Lung cancer, a leading cause of cancer-related deaths globally, is characterized by significant genomic instability, which is a hallmark of various cancers. Despite advancements in understanding the molecular mechanisms underlying lung cancer and the development of targeted therapies, treatment options remain limited, particularly for advanced stages of the disease. Chemotherapeutic agents, especially platinum-based drugs like cisplatin, exploit this genomic instability by inducing DNA damage in rapidly dividing cancer cells. However, the emergence of chemotherapy-resistant tumors presents a significant challenge in treatment efficacy. The DNA damage repair (DDR) pathways play a critical role in maintaining genomic integrity and their dysregulation can lead to increased mutation rates and tumor progression. This research topic aims to explore the intricate relationship between DDR mechanisms and thoracic cancers, focusing on how these pathways can be targeted to improve therapeutic outcomes.

The primary goal of this research topic is to address the challenges posed by DNA damage repair mechanisms in thoracic cancers, particularly non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Despite initial responses to DNA-damaging agents, resistance often develops, undermining treatment effectiveness. To combat this issue, it is essential to investigate novel therapeutic strategies that target specific DDR pathways. This includes exploring the potential of inhibitors that disrupt key proteins involved in DDR. Furthermore, understanding the mechanisms of resistance that arise during treatment will be crucial for developing more effective combination therapies that integrate DDR inhibitors with existing treatments like immunotherapy. By identifying novel biomarkers associated with DDR deficiencies, we can enhance patient stratification and tailor treatments to improve clinical outcomes.

This Research Topic invites contributions that delve into various themes related to DNA damage repair in thoracic cancers. Specific areas of interest include:

• Mechanisms of DNA Damage Repair: Detailed analyses of homologous recombination (HR), non-homologous end joining (NHEJ), base excision repair (BER), and other pathways.
• Therapeutic Strategies: Investigations into novel inhibitors targeting DDR proteins and their combination with existing therapies.
• Biomarkers: Identification and validation of biomarkers predictive of response to DDR-targeted therapies.
• Resistance Mechanisms: Exploration of molecular mechanisms underlying resistance to DDR inhibitors.
• Tumor Heterogeneity: Studies addressing inter- and intra-tumoral heterogeneity and its impact on treatment outcomes.

We welcome a range of manuscript types, including original research articles, reviews, case studies, and commentaries that contribute to a deeper understanding of the role of DNA damage repair in thoracic cancers and its implications for therapy.

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).
