Welcome to the ACRO 2026 Abstract Submission Site

ABSTRACT SUBMISSIONS GUIDELINES AND INSTRUCTIONS

ACRO is accepting abstracts for both physician/clinical consideration, and for SEAL (RadOnc Leadership & Admin) consideration:

Physician/clinical abstracts are accepted for a variety of topics, including, but not limited to, Breast; CNS; GI; GU; GYN; Head/Neck; Lymphoma/Hematology; Thoracic; Benign/Palliative; Contouring, Safety & QA; Job Market, Business, Education & Diversity; Physics/Dosimetry/ Technology.

For submissions on ACRO Grant-supported initiatives, please use the submission portal, and mark both the type and category as such.

Abstracts to be considered for the SEAL Program should use this submission portal, and mark both the type and category as such. The SEALs are RadOnc non-physician leaders: administrators, lead therapists, nurses, and dosimetrists, and others in leadership roles. Topics generally of interest to this group are Recruiting, Staff Engagement and Development, Leadership, Quality Initiatives, Safety, and Patient Experience.

Abstract system opens for submissions: July 25 2025 for all submissions.

Deadline for abstract submissions: Oct 3 at 11:59 PM EST for all submissions.

Abstract submitters will be notified no later than the week of November 10, 2025 whether your abstract has been accepted.

There are very limited spots available for oral presentations. If you select that you want to be considered for an Oral Presentation only, please be aware that based on scoring, you may not be awarded an oral presentation opportunity, but may instead be offered a spot in the Poster Display.

Abstracts accepted by the committee will be showcased at the Summit. ALL acceptances will participate in event, most in a poster session on Thursday, Feb 5, or Friday, Feb 6, 2026. Poster specifications will be distributed with acceptance notices in November 2025.

High-scoring abstracts may also be invited to submit their research for publication in CURiE, ACRO's online Journal.

Acceptance of the abstract by the committee obligates the author to present the poster and pay the meeting registration fee. If circumstances prevent attendance, you must notify ACRO and arrange for an alternate presenter, preferably a co-author. The representative presenting the abstract must register no later than December 1, 2025.  If you are not already an ACRO member, we would encourage you to fill out the online membership form prior to registering for the meeting if you want to take advantage of our members-only discounted registration fee and additional member benefits.  

Submission of an abstract conveys permission for your abstract to be posted online and on the event app.

Abstracts of impactful prospective clinical trials in progress allow investigators to present ongoing trials, develop collaborations, foster accrual, and discuss trial correlatives. Abstracts of such trials in progress will be considered for poster only. Case reports that provide strong educational value and describe particularly novel presentations, treatment outcomes, or toxicities can be considered for poster only.

Restrictions

If the abstract has been previously published as a manuscript in a journal, it will not be acceptable for the Radiation Oncology Summit 2025. If the abstract has previously been presented at another national meeting (e.g., ASTRO), it is eligible for submission to the ACRO Radiation Oncology Summit. For such cases, expanded analyses or updated data are encouraged.

Industry Submissions: The ACRO Summit does not accept industry-supported abstracts or posters.

How to submit an abstract

Important Information: please read before trying to enter the system 

1. For each abstract you submit, you MUST use the online submission system.
2. The text of your abstract must be entered in the text field in the submission form. A Word document abstract sent by email will not be accepted. It is advisable to create the abstract first in Word on the hard drive of your computer, then ‘cut and paste’ the full abstract into the field of the submission form.
3. If you have not used the Cadmium Abstracts system previously, you’ll set up a new submitter account.  To log in as a registered submitter (NOT a NEW submitter), enter your email address and the password you chose when you registered with the system.
4. If you are submitting more than one abstract, you can use the same email address and password for all abstracts.
5. When you click the “log in” button, you will be taken to a screen from which the submission process starts. Please read the instructions on this screen carefully.
6. Each abstract must NOT exceed 450 words (including references). If you try to submit more than 450 words, the system will notify you that you have exceeded the limit and will only accept the first 450 words. The title does not count against the 450-word limit; however, tables you enter do count against the limit.
7. Please use the standard scientific format of Purpose, Methodology, Results, Conclusions. References, if used, should be limited to no more than four references. The submission form provides separate fields for you to enter these sections of your abstract, and the text entered in all those fields, combined, will be limited to 450 words, including references.
8. Once you have completed your abstract entry, click the “Submit” button. If you have answered all the mandatory questions, including disclosure of potential conflicts of interest, your abstract will be assigned a reference number and you will receive an email confirming that your abstract was successfully submitted. If you have not answered all the mandatory questions, your abstract will be held in temporary storage until you complete all questions. Please refer to the reference number if you need to contact the ACRO office regarding your submission.

Amending a submission

If you wish to change your answers to some of the questions on the submission form, or even to change the abstract itself before the deadline, you will need to:  

• Log in to the submission system and click the button that says, “Amend a Previous Submission.”
• You will see a list of the abstracts that you have submitted. Click on the abstract that you wish to change.
• The process of amending an abstract is the same as the original submission process, except that the submission form will be automatically filled in with the answers that you gave previously. You do not have to change an answer if you do not want to.
• If you want to change your abstract, either edit it directly OR delete the abstract in the system and cut and paste the updated version as you did initially. If you do not want to change the abstract, just press “Submit” to bypass this step.
• When you reach the final step and press “Submit,” you will be sent an email confirming that your abstract has been amended – provided you have answered all the mandatory questions.

Withdrawing an abstract or assistance with problems 

If you wish to withdraw an abstract, or if you have problems or questions, please contact the staff in the ACRO office:  sallie@acro.org.
