The AANS CNS Joint Section on Tumors

What The AANS CNS Joint Section on Tumors does

The AANS/CNS Joint Section on Tumors is a nonprofit professional medical organization established in 1984 and operating as a joint section under the American Association of Neurological Surgeons (AANS) and the Congress of Neurological Surgeons (CNS). Headquartered in Rolling Meadows, Illinois, the section provides a forum for education and research on tumors of the nervous system. Its primary constituents are board-certified and training neurosurgeons specializing in brain and spinal tumor surgery, with a secondary audience of neuro-oncologists. The section's mandate is to coordinate activities and programs relating to nervous system tumors across AANS, CNS, and other societies, committees, and agencies, and to represent the two parent organizations on tumor-related matters.

The section's product portfolio centers on professional membership with associated benefits, including an annual online subscription to the Journal of Neuro-Oncology and discounted access to the Biennial Tumor Satellite Symposium. Educational programming is delivered through the AANS/CNS Tumor Section Webinar Series (formerly the Journal of Neuro-Oncology's Tumor Talk), tumor-specific clinical guidelines approved by CNS/AANS guidelines committees, and an archived digital library on YouTube. Additional core offerings include the Neuro-Oncology Fellowship Match program operated in conjunction with the Central Application Service for Neurosurgery Fellowships (CAST), research funding administered via the Neurosurgery Research and Education Foundation (NREF) and six named memorial funds, awards programs recognizing excellence in neuro-oncology, clinical trial resources, patient education materials developed in collaboration with the MyTumorID campaign, and a neurosurgical atlas reference resource.

The organization's revenue is driven primarily by membership dues structured across multiple professional categories, supplemented by philanthropic contributions through named memorial funds and grants administered via NREF. Distribution occurs through direct membership enrollment via its website (https://www.tumorsection.org), with engagement across six social media channels (Twitter/X, LinkedIn, Facebook, Instagram, YouTube, and email newsletters). The entity is not a commercial enterprise and does not publicly disclose revenue, pricing, or financial performance; its primary function is professional society coordination, continuing education, fellowship placement, and guideline issuance in neuro-oncology rather than product commercialization.

Expansion highlights5 records

Broad incumbents

• American Academy of Neurology (AAN): Broad neurology professional society with neuro-oncology programming. Comparable membership society model serving neurologists who treat or research brain tumors, with overlapping CME and guidelines portfolio.
• Congress of Neurological Surgeons (CNS): Co-parent organization of the Joint Section on Tumors. Broad incumbent neurosurgical society that shares membership and jointly funds tumor-focused programming; provides overlapping continuing education and guidelines.
• Society of Neurological Surgeons (SNS): Senior neurosurgical academic society in which current Tumor Section Chair Hadjipanayis serves as Research subcommittee Chair. Adjacent professional society with overlapping leadership and residency program focus.
• American Society of Clinical Oncology (ASCO): Premier U.S. oncology professional society. Overlaps with the Tumor Section's neuro-oncologist members through ASCO's brain tumor track, guidelines, and the Journal of Clinical Oncology.
• American Association of Neurological Surgeons (AANS): Parent organization of the Joint Section on Tumors. Broad incumbent neurosurgical society serving all neurosurgeon subspecialties with meetings, journal (Journal of Neurosurgery), and continuing education — overlapping membership base.

Others

• AANS/CNS Joint Section on Cerebrovascular: Sibling joint section structure under the same AANS/CNS parent organizations. Operates an analogous subspecialty society model (membership, guidelines, awards, meetings) within neurosurgery, useful as a structural comparison for governance and growth dynamics.

Regional players

• European Association of Neuro-Oncology (EANO): European counterpart neuro-oncology professional society with annual meetings, guidelines, and the journal Neuro-Oncology Practice. Comparable scope, but primary geographic focus is Europe rather than North America.
• World Federation of Neurosurgical Societies (WFNS): Global umbrella neurosurgical federation. Comparable international professional society model with member societies worldwide, relevant as the Tumor Section pursues global expansion (signaled by the Global Neurosurgery Oncology Award).

Direct peers

• Society for Neuro-Oncology (SNO): Largest international multidisciplinary neuro-oncology society. Directly comparable professional society serving the same neuro-oncology specialist community with meetings, journal (Neuro-Oncology), and educational programming.

Emerging players

• North American Skull Base Society (NASBS): Adjacent subspecialty society focused on skull base tumors. Partial overlap with neuro-oncology case mix and surgical audience; analogous niche-society business model with annual meeting and member dues.
