Abstracts

Abstracts will be scored by blind peer review based on the following criteria:

• Does the abstract address an important and novel question?
• Does the study design permit the question to be answered?
• Are the endpoints of the study clearly defined?
• Is there an appropriate use of statistics?
• Are the methods described in sufficient detail?
• Are the conclusions supported by the data?

Specific questions for prospective Clinical Trials:

• What were the scientific hypothesis and primary endpoint?
• What were the eligibility criteria and study patient characteristics?
• What statistical model and assumptions were used?
• What was the toxicity assessment?
• What were the limitations?
• Was there a rationale, either clinical or laboratory, underlying the study design?
• Are the findings either promising enough to pursue or negative enough that presentation would prevent other investigators from wasting efforts?

Specific questions for retrospective observational studies:

• What are the scientific hypothesis and outcomes reported?
• What is the data source and how was follow-up attained?
• Is the cohort well described and reasonably homogeneous?
• Have attempts been made to account for biases inherent in retrospective reviews?
• What statistical methods were used?
• Are the conclusions appropriate to the study design?

ASTRO is an accredited provider of continuing medical education and adheres to the policies and standards set forth by the Accreditation Council for Continuing Medical Education (ACCME). As such, abstract authors are required to disclose relationships with commercial interests. A commercial interest is any entity producing, marketing, re-selling, or distributing health care goods or services consumed by, or used on, patients. The financial relationships of spouse/partners are considered relevant financial relationships of the presenter. (Employment of spouse/partner is not considered employment by the presenter; however, it will be considered a relevant financial relationship.)

To ensure its compliance, ASTRO expects that the content and related materials will promote improvements or quality in health care and not a specific proprietary business interest or commercial bias.

We employ several strategies to ensure absence of bias:

• Presenters are required to provide disclosure of relationships with commercial interests.
• Presenters are required to provide a balanced view of therapeutic options.
• All abstracts undergo a rigorous peer review process.
• Potential conflicts are managed by committee review, session audits, and in some cases advance slide review.

Abstracts should be submitted in the most appropriate category. A list of submission categories is listed below and in the online submission site. Planning committees have the right to re-categorize any abstract as deemed appropriate. If your abstract is a trial in progress, please indicate this on the abstract submission site.

Trials in Progress provide an opportunity for members of the research community to present ongoing trials, foster collaboration, and discuss correlatives and novel trial designs. Trials in Progress will be considered for digital poster only.

• All phases of clinical research (phases I to III, supportive care, nonpharmacologic interventions) may be considered for inclusion as a Trials in Progress submission.
• Trials submitted to this session are ongoing and have not reached pre-specified endpoints for analysis. As such, inclusion of results would be improper and is strictly forbidden.
• Enrollment must have already begun or have been completed with no data analysis available by the submission deadline (there are no exceptions to this criterion). It is acceptable if the trial has not enrolled its first patient yet.
• Clinical trial registry number (required)

1. Sponsorship or membership with one of the co-sponsoring organizations is not required to submit an abstract.
2. Abstracts must be received by 11:59 p.m. Pacific time on Wednesday, September 15. Please be sure to click “submit” before 11:59 p.m., as the abstract may not fully transfer and you risk being ineligible by having an “incomplete” status. Abstracts received after the deadline will not be accepted and incomplete abstracts will be considered ineligible for review.
3. Abstracts must be submitted online through the abstract submission site. No faxed copies, discs, thumb drives or email submissions will be accepted.

4. An abstract may only be submitted to the 2021 Multidisciplinary Thoracic Cancers Symposium once. Duplicate abstracts (reporting the same data) that are submitted under a different title or author will not be considered.

5. Summaries of new, ongoing and updated research in the areas of thoracic oncology are acceptable for submission and presentation. We currently accept trials in progress; the planning committees will consider if digital poster or oral presentation is appropriate when determining abstract selection and placement.
6. Abstracts may be submitted from commercial entities (those producing, marketing, re-selling or distributing health care goods or services consumed by, or used on, patients) reporting on the discovery of their scientific research. Such presentations will be subject to a rigorous peer review process to ensure the validity of the research review process, results and conclusions. In addition, abstract content is subject to editing after review so that it is not biased towards any proprietary or commercial interests. The planning committees will exercise all rights in ensuring that abstracts reporting the discovery of scientific research remain in compliance with ACCME standards for ensuring independence in CME activities. If accepted, the abstract must be presented by an author with no relevant financial relationship or any commercial interest.

7. Submission of an abstract conveys permission for the full text to be published in the International Journal of Radiation Oncology • Biology • Physics (Red Journal) as well as the meeting website/online conference planner.

8. NOTIFICATIONS: You will be notified via email of the disposition of your abstract by early-October. Acceptance of the abstract by the committees obligates the author to register and attend the meeting. If circumstances prevent attendance, you must notify ASTRO and arrange for an alternate presenter, preferably a co-author.

9. REVISIONS: Please proof your abstract carefully for formatting, spelling and data errors. Pay special attention to the author order and presenting author designation. Errors can be corrected if emailed to ASTRO's education team by Monday, October 18, 2021.

10. WITHDRAWALS: If you choose to withdraw your abstract, email your request by Monday, October 18, 2021 to ASTRO's education team. Presenters who fail to notify ASTRO staff of withdrawal and do not present their oral abstract(s) and/or upload their digital poster(s) may face automatic rejection from future symposia as determined by future planning committees.

1. An individual may submit more than one abstract in which he or she is indicated as the first author, but he or she may only present one oral presentation. If more than one abstract is selected for oral presentation, an alternate presenter must be assigned, preferably a co-author (this does not apply to poster presentations).
2. It is the submitter’s responsibility to ensure up-to-date and accurate disclosures are submitted for each co-author on the abstract. ASTRO manages and reports all disclosures as submitted. Potential conflicts with commercial interest for the presenting author and all co-authors must be disclosed at the time of submission.

3. A commercial interest is defined as any entity developing, producing, marketing, re-selling, or distributing healthcare goods or services consumed by or used on patients.) Any potential conflict will be identified and managed according to ACCME guidelines and ASTRO’s COI management policies.

4. The presenting author of an abstract must NOT have a relevant/specific ownership interest (owner, founder, partner, etc.) in the scientific content in the abstract. If a conflict of interest exists, the abstract must be submitted and presented by a co-author with no relevant ownership interests.

5. If the presenting author is employed by a commercial interest, as defined above, an alternate presenter must be named. This applies only to abstracts presented in sessions selected to receive CME (oral presentations).

6. All oral and digital poster presenters are required to register and attend the meeting. Presenters who fail to arrange for an alternate presenter or fail to notify ASTRO staff of withdrawal and subsequently do not present at the meeting and/or upload their digital poster may face automatic rejection from future symposia as determined by future planning committees.

7. The presenting author will receive all notifications and communications related to the accepted abstract(s) and is responsible for informing all co-authors of acceptance and COI policies.

8. All oral abstract presenters must abide by the following expectations:
   1. You are required to disclose before your talk. Presenters are required to disclose the following, if applicable, to the audience at the beginning of your presentation and in accordance with ACCME standards and Food and Drug Administration requirements:
      1. The existence of any financial or other relationship you have with the manufacturer(s) or any commercial product(s) or provider(s) of any commercial services discussed in an educational presentation.
      2. Any vested interest or intention to discuss off-label use of pharmaceuticals or devices.
   2. Presentations must be objective and free of commercial bias for or against any product or device. Slides and/or reference materials shall not, by their content or format, advance the specific proprietary interests of a commercial entity.
   3. All clinical recommendations must be based on evidence that is accepted within the profession as adequate justification for their indications and contraindications in the care of patients. All scientific research referred to, reported or used to support or justify a patient care recommendation must conform to the generally accepted standards of experimental design, data collection and analysis.
   4. Presentations must give a balanced view of therapeutic options. Use of generic names will contribute to this impartiality. If trade names are used, those of several companies should be used rather than only that of a single supporting company.
   5. Presentations must offer a balanced view of current medical practice that includes discussion of all available therapeutic products, including benefits and risks associated with each.
   6. Presentation materials must not include any commercial logos.
   7. Presentations must be HIPAA compliant (e.g., will only use de-identified patient information and/or will obtain written consent from the patient).

1. Abstracts should contain new material that will not have been presented or published prior to the 2021 Multidisciplinary Thoracic Cancers Symposium (exceptions noted below). If an abstract reporting the same data has been submitted for consideration at another meeting or for publication and you have not received notification of its acceptance at the time of your abstract submission, you will be required to disclose the information during the abstract submission process. Previously presented or published works will not be considered for plenary presentation.
2. An exception applies to abstracts submitted or presented at ASCO, ASTRO, SITC, or STS sponsored or co-sponsored meetings. Abstracts submitted to prior ASCO, ASTRO, SITC, or STS meetings, including annual conferences, will be considered for acceptance but are encouraged to contain new or updated material.
3. Abstract presenters with papers accepted for presentation at another major medical meeting (including annual meetings of national and international societies with attendance of more than 3,000 participants) or accepted for publication after Monday, August 30, 2021, are required to notify ASTRO of the change in status by email to ASTRO's education team. The planning committees will review and decide on a case-by-case basis if it will remain in the program.

1. Abstracts must be properly formatted and organized into four sections, identified by the following bolded headers: Purpose/Objectives, Materials/Methods, Results, and Conclusion.
2. When applicable, abstracts should include a scientific hypothesis in the Purpose/Objectives section and implications for research, policy, or practice in the Conclusions section.
3. Presentations must give a balanced view of therapeutic options. Brand names of pharmaceuticals and trade names of medical devices should not be used in the title or body of the abstract. Use of generic names will contribute to impartiality. Planning committees have the right to replace proprietary names with generic names.
4. Institution names should not be included in the title or body of the abstract in order to keep the review process blind, fair and objective. Alternative language includes “at one institution,” “a multi-institution study,” etc. This does not apply to cooperative research group names.
5. Abstracts cannot contain illustrations, images or graphs. For abstracts that are accepted, presenters may include these items in their on-site presentations.
6. An abstract may contain one small table.
7. The title of the abstract should not contain results.
8. The maximum character limit, including the abstract title and body, is 2,600. Spaces are not counted.
9. A maximum of 20 author names may be listed on each abstract; there are no exceptions. Authorship credit should only be given if all three of the following criteria are met:

• Conception and design, or analysis and interpretation of data, and
• Drafting the abstract or revising it critically for important intellectual content, and
• Final approval of the version to be submitted/published.

Two awards will be granted to recognize outstanding abstracts submitted by early career authors. More information about the award and the award application will be available on the actual abstract submission site. Complimentary registration to the symposium is included in the award.

All abstracts to be presented at the 2021 Multidisciplinary Thoracic Cancers Symposium are embargoed until Thursday, December 2 at 8:00 a.m. Mountain time.  The embargo policy applies to all abstracts regardless of whether information is obtained from another source.

Embargo violations by media professionals may result in suspension of credentials at the 2021 Multidisciplinary Thoracic Cancers Symposium as well as future meetings and may also impact the ability to receive advance media materials for future meetings. Embargo violations by abstract authors and/or sponsors may result in removal of the abstract from the scientific program. Abstract authors are responsible for notifying financial and other sponsors about this embargo policy. Questions about the embargo policy may be directed to the ASTRO media relations team.

All abstracts accepted for presentation at the 2021 Multidisciplinary Thoracic Cancers Symposium may be highlighted in the symposium Press Program. All submitters agree to cooperate in the publicity of their study. For questions regarding the press policy, please contact ASTRO’s media relations.

Authors of abstracts accepted as digital posters will be required to upload their poster in advance of the meeting. All formatting requirements are pre-set, so it's easy to cut and paste your information into the template. With this new format, presenters may also include audio, video and other graphics.

There will a $70 fee per poster for digital upload, payable at the time of upload. The fee has been set at a price that is substantially lower than traditional paper printing, and we are confident that this new format will provide greater visibility of every poster than the previous paper format. Attendees will be able to access digital posters in an online virtual library both on-site and after the conclusion of the symposium.
