AI Tumor Board

What this is

AI Tumor Board is an open-source demo of a multidisciplinary oncology board run by six specialist AI agents — a radiation oncologist, medical oncologist, surgical oncologist, clinical pharmacist, molecular oncologist, and pathologist. Paste a clinical vignette and watch the agents independently research the case across PubMed, ClinicalTrials.gov, openFDA, DailyMed, RxNorm, CIViC, and the open web, then discuss across rounds until they converge on a consensus recommendation.

Every recommendation is grounded in evidence retrieved at run-time. Agents that cannot find supporting evidence abstain rather than answer from training knowledge. Citations link to the underlying source.

How it works

• Six Gemini 3.1 Pro specialist agents, each with a specialty-specific tool subset and PubMed MeSH bias.
• Two are conditional: the molecular oncologist activates only when biomarker data is present; the pathologist activates only when there is diagnostic ambiguity.
• Strict evidence-only rule: every clinical claim must be backed by an [E#] citation. (judgment) annotations are not accepted.
• Discussion loop: round 1 is independent research; subsequent rounds prepend the other specialists' positions plus the board chair's open questions. The loop continues until consensus (alignment ≥ 0.85) or a 4-round safety cap.
• Live streaming UI via Server-Sent Events — you watch each agent's tool calls, drafts, and the chair's verdict as they happen.

Tech stack

About the author

Dr. Roupen Odabashian

Dr. Roupen Odabashian is a hematology–oncology physician and the founder of MeDucation AI, a platform reimagining how the next generation of oncologists learn. His clinical work at the bedside — where treatment decisions hinge on rapidly evolving evidence, complex genomics, and the realities of individual patients — is the foundation for everything he builds. He created this AI Tumor Board as an educational space where trainees, fellows, and practicing clinicians can work through real oncology cases alongside AI, sharpening clinical reasoning outside the time pressure of a live conference room.

A practicing physician and an active voice in healthcare AI, Roupen works at the intersection of medicine and technology — translating what bedside oncology actually needs into tools clinicians will actually use. He hosts the Delta HealthTech podcast, where he sits down with the founders, researchers, and clinicians shaping the future of healthcare, and he writes and speaks regularly about how large language models are reshaping clinical education and decision-making.

His mission is simple: make oncology learning faster, deeper, and more accessible, and put modern AI in the hands of every clinician who treats cancer.
