Can AI outthink cancer experts? a landmark trial pits five AIs against tumor boards
NCT ID NCT07739121
First seen Jul 31, 2026 · Last updated Jul 31, 2026
Summary
This trial asks whether five advanced AI models can match the treatment recommendations of expert tumor boards for cancer patients. Using 100 standardized synthetic cases across breast, lung, urological, digestive, and gynecological cancers, each AI and two independent tumor boards provide treatment plans. The plans are scored for agreement with established guidelines and for potential harm. The goal is to see if AI can reliably support cancer treatment decisions, not to replace human experts.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Frontier large language models (AI) compared with multidisciplinary tumour board recommendations
- What this could lead to
- If AI matches expert tumor boards, it could support doctors in making consistent, guideline-based cancer treatment decisions, potentially improving care quality and accessibility.
- What could go wrong
- This is a non-interventional benchmark using synthetic cases, not real patients. AI may still make dangerous errors, and results may not reflect real-world clinical practice.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
100 synthetic oncology treatment-planning cases (20 per localisation) across five localisations: breast, lung, urological (prostate, bladder / upper-tract urothelial, kidney), digestive and gynaecological. Each case is a structured JSON input specifying UICC 8th-edition stage, biomarkers, ECOG performance status, comorbidities and a standardised clinical question. No human participants, no patient data and no identifiable individuals. Recommendations are produced by two independent tumour boards per localisation and by five frontier LLMs (queried May 2026).

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Synthetic oncology case within one of the five predefined localisations (breast, lung, urological, digestive, gynaecological). * Complete structured schema: UICC 8th-edition stage, biomarkers, ECOG performance status, comorbidities and a standardised clinical question. * A clinically answerable treatment-planning question that is mappable to the locked guideline matrix. Exclusion Criteria: * Case outside the five predefined localisations. * Incomplete, internally inconsistent or ambiguous schema. * Duplicate or near-duplicate of an existing case in the set. * Question not resolvable by current guidelines.
