Special Issue Information

Dear Colleagues,

In 2009, AAPM (American Association of Physicists in Medicine) hosted a special symposium on “The Promises and Perils of Proton Radiotherapy”. The late Michael Goitein gave the opening talk, “Past, Present and Future”.  At that time, there were less than 10 proton therapy facilities operating in the US. Currently, there are 39 proton therapy centers in the US, and we are on the verge of building a carbon ion therapy center. This issue will attempt to look at the progress achieved since then. Intensity-modulated proton therapy (IMPT) has become the standard method of delivery. Medical physicists tout the promise of proton therapy as exhibited by the superior depth-dose deposition. Practitioners enjoy treatment plans able to spare large volumes of normal tissue. Meanwhile, substantial improvements in clinical outcomes are less easy to conclusively demonstrate. Has proton therapy lived up to our expectations? What new clinical evidence do we have supporting protons? What perils do we still need to address? How are uncertainties being managed? Is cost still a major issue? Is this the future we saw, and if not, when do we expect it?

In this Special Issue, we invite articles addressing clinical topics, both successes and work remaining to be carried out. In particular, this issue should address the state of the art in:

  • Pediatrics, including issues around brain necrosis;
  • Quality of life;
  • Motion management, particularly in lung, liver, and esophageal cancer;
  • Cardiac sparing;
  • Target margins and uncertainty;
  • Cost effectiveness;
  • Issues around randomized clinical trials;
  • Biological uncertainties.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cancers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Background: Adolescent and young adult cancer patients are at high risk of developing radiation-associated side effects after treatment. Proton beam radiation therapy might reduce the risk of these side effects for this population without compromising treatment efficacy. Methods: We review the current literature describing the utility of proton beam radiation therapy in the treatment of central nervous system tumors, sarcomas, breast cancer and Hodgkin lymphoma for the adolescent and young adult cancer population. Results: Proton beam radiation therapy has utility for the treatment of certain cancers in the young adult population. Preliminary data suggest reduced radiation dose to normal tissues, which might reduce radiation-associated toxicities. Research is ongoing to further establish the role of proton therapy in this population. Conclusion: This report highlights the potential utility of proton beam radiation for certain adolescent young adult cancers, especially with reducing radiation doses to organs at risk and thereby potentially lowering risks of certain treatment-associated toxicities.
