ASCO Guidelines Assistant vs DynaMed (2026)
A specialty society's own guidelines in conversational form, against a general disease reference. The ASCO Guidelines Assistant answers only from the American Society of Clinical Oncology's published guidelines. ASCO built it with Google Cloud on Vertex AI using Gemini models, designed it to decline when its guidelines do not cover a question, and includes it with membership. DynaMed covers all of medicine under a stated seven step evidence method. Its Dyna AI answers from DynaMed's own content and labels what it generates. These are complements, not alternatives. The ASCO assistant speaks with the authority of the body that writes oncology guidance and is silent outside it, and much of what comes up in an oncology clinic is general medicine.
- Answers from the society that writes the oncology guidelines, rather than a publisher's summary of them.
- A named model and platform: Gemini on Google Cloud's Vertex AI.
- Designed to decline when its guidelines do not cover the question, and included with ASCO membership.
- Coverage across all of medicine, not one specialty.
- An ISO 27001 certificate covering DynaMed by name, downloadable from EBSCO's trust page.
- SMART on FHIR and HL7 integration for DynaMed Decisions, which reads a patient's record to tailor recommendations.

Both records were reviewed on this site in September 2026. ASCO publishes no evaluation of the assistant, and asks users never to enter patient information because it is not a HIPAA protected environment. Dyna AI has no published accuracy study either.
Ask ASCO how often the assistant declines a question, and ask DynaMed how quickly a new ASCO guideline reaches its oncology entries.
