Summary

TumorBoard is a multi-agent decision-support system for neuro-oncology that integrates specialist AI agents, a shared longitudinal case state, and an auditable claim-evidence ledger. It significantly improves diagnostic and therapeutic recommendations by exposing contradictions and ensuring evidence sufficiency.

Making informed decisions in neuro-oncology is complex, requiring the synthesis of diverse data like MRI scans, pathology reports, molecular markers, and treatment history. TumorBoard introduces a sophisticated multi-agent decision-support system designed to streamline this process. It features specialized AI agents for areas such as radiology, neuropathology, and therapy planning, all contributing atomic claims with clear provenance to a shared longitudinal case state.The system incorporates an adversarial critic to identify contradictions among agent claims and a safety governor that qualifies or defers recommendations based on evidence sufficiency and temporal validity. In evaluations on a 360-case benchmark, TumorBoard demonstrated superior performance in action F1 and evidence entailment compared to baseline systems. The safety governor proved effective in reducing harmful recommendations by deferring unsafe cases, highlighting the critical role of structured coordination in achieving multi-agent advantages.

Why it matters

Healthcare professionals and AI developers in medicine can leverage multi-agent AI systems like TumorBoard to enhance diagnostic accuracy, improve treatment planning, and ensure evidence-grounded decision-making in complex medical fields like neuro-oncology.

How to implement this in your domain

  1. 1Explore the architectural principles of TumorBoard for designing multi-agent systems in other complex medical domains.
  2. 2Investigate how an auditable claim-evidence ledger can be integrated into existing clinical decision support tools.
  3. 3Pilot a multi-agent system with adversarial critics and safety governors for specific high-stakes medical scenarios.
