SIOG - International Society of Geriatric Oncology

What SIOG - International Society of Geriatric Oncology does

The International Society of Geriatric Oncology (SIOG), founded in 2000 and headquartered in Geneva, Switzerland, is an international multidisciplinary non-profit professional society dedicated to improving cancer care for older adults. Its core offerings function as an interconnected platform rather than a single product: the Journal of Geriatric Oncology (official scientific journal), the SIOG Annual Conference (flagship in-person event), the SPARC patient advocacy program, and the SIOG Consortium form the core, supported by educational products including SIOG Advanced Courses (delivered in locations such as Canberra and Treviso), the SIOG Toolkit, SIOG Blog, and SIOG Webinars. Research and consensus-building activity is conducted through multiple SIOG Working Groups (Tumour Task Forces, Methods, Translational Research, Global Clinical Practice, COVID-19, Designation Centers) and Horizon Europe-funded projects (GerOnTe, LifeChamps, Interact-Europe), while the Young SIOG (YSIOG) interest group engages early-career professionals through publications, mentorship, and awards.

The society's technology stack is conventional rather than proprietary — WordPress, WooCommerce, Google Analytics, Stripe, and standard social media integrations support the website, online store, and member services; SIOG operates no AI or data platform. Its business model is a typical non-profit professional society construct, monetized through five primary revenue streams: recurring annual membership fees from 1900+ individual healthcare professionals across 80+ countries, conference registration and sponsorship revenue, corporate memberships and program sponsorships from pharmaceutical and oncology companies, fees from advanced courses and educational handbooks, and journal subscription income. The organization holds Special Consultative Status with the United Nations Economic and Social Council (ECOSOC) and is governed under the Swiss Civil Code as a non-profit association with 23 employees, supported by a 300+ multidisciplinary expert faculty and partnerships with ESMO, ASCO, EORTC, CACA, and a broader Partner Societies Network.

Direct peers

• American Geriatrics Society (AGS): AGS is a U.S. professional society for geriatricians, mirroring SIOG's role on the geriatrics side of the geriatric-oncology intersection. It uses an analogous membership, journal, and annual-meeting model and serves an overlapping multidisciplinary audience.
• European Geriatric Medicine Society (EuGMS): EuGMS is the European counterpart to AGS, focused on geriatricians and gerontology professionals. It runs a congress, journals, and special interest groups in a structure closely paralleling SIOG's, with overlap on the geriatric side of geriatric oncology.
• The Gerontological Society of America (GSA): GSA is a multidisciplinary membership society for researchers and practitioners in aging. Its annual scientific meeting, journal portfolio, and interest-group structure are highly comparable to SIOG's operating model, even though oncology is only one of many disciplines it covers.

Broad incumbents

• European Society for Medical Oncology (ESMO): ESMO is SIOG's primary European partner, co-running the ESMO/SIOG Cancer in the Elderly Working Group. It operates a similar membership-and-conference model across medical oncology in Europe and is the closest direct counterpart by structure and audience.
• European Hematology Association (EHA): EHA is a European membership society for hematology professionals, comparable to SIOG in operating model (membership, annual congress, journal, working groups) and in addressing a specialty where older patients are a major share of the population.
• American Society of Clinical Oncology (ASCO): ASCO is the largest U.S. oncology professional society and a core SIOG partner (joint publications, conference engagement, Young SIOG support). It serves a much broader oncology membership but overlaps in geriatric oncology initiatives, making it the most direct comparable incumbent.
• European Cancer Organisation (ECO): ECO is a pan-European umbrella federation of oncology societies and an analogue of the broader oncology ecosystem in which SIOG operates. It shares SIOG's advocacy and guideline-development role at a European scale.

Emerging players

• International Society of Nurses in Cancer Care (ISNCC): ISNCC is an international membership society for oncology nurses, overlapping with SIOG's nursing and allied-health audience. It uses a similar membership, conference, and educational program model.
• International Association for the Study of Lung Cancer (IASLC): IASLC is a global multidisciplinary society for thoracic oncology with a comparable membership-and-conference operating model. It complements SIOG where lung cancer in older adults is addressed and shares the 'small-staff, global-footprint' archetype.
• Multinational Association of Supportive Care in Cancer (MASCC): MASCC is an international multidisciplinary society focused on supportive care in cancer. Like SIOG, it operates on a membership + annual meeting model, but addresses a broader (non-age-specific) clinical niche, making it a structurally comparable peer with partial topical overlap.
