A study published in September 2026 introduced SentryLine, an AI system designed to answer clinical questions using oncology documents that change over time.

The system aims to detect when a recommendation has been updated and provide answers with references and temporal verification. The goal is to reduce the risk of relying on an outdated recommendation after a guideline has changed.

An increasingly relevant problem

Living guidelines can evolve as new evidence emerges. The study is a proof of concept and does not replace clinical responsibility, but it illustrates a way to make the version and timing of evidence more visible.
