About this Research Topic

Background

Vascular malformations are due to congenital anomalies of blood and lymphatic vessels. The knowledge of vascular anomalies has grown in the last few decades with the identification of key molecular pathways and genetic mutations that drive the formation and progression of vascular anomalies. Many of these blood vessel malformations are evident at birth, others do not appear until later in childhood and adolescence. Vascular malformations are part of the group of vascular anomalies which in turn is distinguished from the group of vascular tumors. Vascular malformations can appear anywhere on the body as a mass of soft tissue, causing pain, swelling and/or discoloration of the skin, blood clotting problems, organ damage, functional or cosmetic problems. Vascular malformations are rare and occur in about 1% of all births with a frequency of 1 person in 5,000-10,000 people for the venous malformations, the most common type. To date, the treatments available focus on reducing symptoms through sclerotherapy, catheter embolization, laser treatments and radiation therapy (radiosurgery).

Given the rarity of these vascular anomalies and the number of different types of malformations, diagnoses are often difficult, therefore genomic studies are required. Unfortunately, genetic tests involve painful tissue biopsies which are not always feasible and cause anxiety for the patient. For this reason, the need for various professional figures such as surgeons, geneticists, and bioinformatics to collaborate is growing more and more to fill the gap with their expertise for scientific progression. In fact, in recent years liquid biopsy has appeared as a new oncological investigation technique but its application has also extended to the field of vascular malformations. At the moment there are a few pioneering studies about the application of liquid biopsy for the diagnostic investigation of vascular malformations and for this reason we invite the scientific community to look at this new frontier.

We are pleased to invite you to contribute to the drafting of scientific work which will help to address the current need for precise diagnosis in vascular malformation-affected patients. The special issue aims to identify innovative, non-invasive, and effective strategies to detect the molecular scenario of vascular malformations allowing to avoid any risk of bleeding and to better investigate the therapy tailored to the genetic defect. In this special issue, original research articles and reviews are welcome.

Research areas may include (but are not limited to) the following:
liquid biopsy, vascular malformations, noninvasive techniques, high throughput sequencing, arteriovenous malformation, venous malformation, lymphovenous malformations, innovative technologies, and new strategies.

Keywords: liquid biopsy; vascular malformations; noninvasive techniques; high throughput sequencing; arteriovenous malformation; venous malformation; lymphovenous malformations; innovative technologies; new strategies

Important note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.

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?

  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.

• Who leads a Research Topic? 

  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.

• What is the role of a topic editor?

  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.

• What support will I receive when editing a new Research Topic? 

  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).

• As a junior researcher, can I be involved in editing a Research 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.
