“One Mission, Many Voices
In the fight against childhood cancer, progress doesn’t happen in a silo. It happens at the intersection of surgery and science, nursing and nutrition, advocacy and advanced therapeutics, and medicine and mentorship.
As we enter 2026, we are calling on the entire pediatric oncology community to join us for the SIOP 2026 Congress in San Antonio, Texas (Sept 15-18).
Whether you are a:
- Laboratory Scientist or Researcher uncovering the next breakthrough,
- Nurse or Allied Health Professional providing frontline care,
- Oncologist, Surgeon or Radiation Oncologist refining precision treatments,
- Psychosocial Expert supporting the ‘whole child,’
- Student or Trainee entering as the next generation of thought leaders,
- Survivor or Parent Advocate sharing the essential lived experience…
…Your voice belongs in San Antonio.
The Call for Abstracts is officially OPEN! We invite all disciplines to submit their work. This is your chance to share your expertise with 3,000+ peers from every corner of the globe.
Experience the ‘Big Heart’ of Texas. When the sessions end, the collaboration continues. San Antonio’s world-famous River Walk and its status as a UNESCO City of Gastronomy provide the perfect backdrop for cross-disciplinary networking and inspiration.
Let’s start the year by breaking down silos and building a future where every child can thrive.
Abstract Submission Deadline: March 17, 2026
Don’t forget to tag a colleague who needs to be at SIOP 2026 with you!”
