ABSTRACT SUBMISSIONS WILL OPEN IN SEPTEMBER 2025
If you conduct research on supportive cancer care, you are invited to submit an abstract for the MASCC/ISOO 2026 Annual Meeting. We encourage submissions from both new and experienced researchers. All accepted abstracts will be published in the MASCC journal, Supportive Care in Cancer (electronic version only).
MASCC offers several awards and scholarships to first authors. For those seeking funding to attend the meeting, we encourage you to apply for one. You will have the opportunity to include an award or scholarship application with your abstract during the submission process. For more information, please click here.
The 2026 Annual Meeting will be a fully in-person meeting. All presenting authors must be present in-person in order to share their research. Virtual options will not be available.
