Society of Interventional Oncology

What Society of Interventional Oncology does

The Society of Interventional Oncology (SIO) is a non-profit professional society incorporated in the District of Columbia and headquartered in Washington, DC (2001 K Street NW, 3rd Floor North). Founded in January 2017 and built on the legacy of the World Congress on Interventional Oncology (WCIO), SIO serves nearly 1,000 international members who are practicing interventional oncologists, diagnostic and interventional radiologists, and allied cancer care professionals. Its mission is to advance interventional oncology as the "fourth pillar" of cancer therapy alongside medical, surgical, and radiation oncology.

SIO's core offerings revolve around four revenue streams: (1) individual membership dues; (2) registration and CME fees from events including the flagship Annual Scientific Meeting (rotating North American venues — Las Vegas 2025, Savannah 2026, Toronto 2027), the NEXT Summit, MSK and Breast Cryoablation Master Classes, the POWER Workshop, and the Clinical Trials Methodology Workshop; (3) a tiered industry membership program (President's Circle, Alliance, Collaborator, Partner) — with named partners including AstraZeneca, Johnson & Johnson, Siemens Healthineers, Sirtex Medical, Medtronic, Stryker, BD, HistoSonics, NeuWave Medical, and TriSalus Life Sciences — that provides recurring annual sponsorship revenue; and (4) education programs delivered through the SIO Learning Center, including the free Clinical Trial Collaborative PI Certificate Course (12 modules), on-demand webinars, Talk Tuesdays, and 2025/2026 Conference Recordings priced at $150 (members) / $300 (non-members).

Beyond education, SIO operates as a research sponsor and standards-setting body: it launched the ACCLAIM trial in 2021 (microwave ablation of colorectal liver metastases) and supports the TRIBUTE trial through its grant program, maintains an investigator/site directory via the Clinical Trial Collaborative, and submits formal recommendations to NCCN guidelines for bone and kidney cancer. Patient-facing resources include a Find-a-Doctor Directory and terminology guides across nine disease states. Governance is provided by a Board of Directors comprising leading IO physicians from Harvard, Mount Sinai, MD Anderson, Mass General, UCLA, Penn and international institutions, with day-to-day operations led by Executive Director Jena Eberly Stack.
