AI trained to spot who will develop stomach cancer
NCT ID NCT04840056
First seen Sep 22, 2026 · Last updated Sep 22, 2026
Summary
Researchers are building a machine learning tool to predict which people with intestinal metaplasia or atrophic gastritis will develop gastric cancer. The study includes about 1,300 adults with these stomach conditions, confirmed by tissue samples. The team will combine clinical information and microscopic tissue features to train the algorithm and test how well it identifies future cancer risk.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a machine learning algorithm that predicts gastric cancer risk from clinical and tissue data
- What this could lead to
- If it works, doctors could use this tool to flag which patients with intestinal metaplasia or atrophic gastritis face the highest risk of gastric cancer and need closer monitoring.
- What could go wrong
- The algorithm may not predict cancer accurately enough to be useful, and its performance in this group of patients may not carry over to other populations. It also needs validation before it can guide care.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Clinical data will be collected retrospectively using the Clinical Data Analysis and Reporting System (CDARS) and Clinical management System (CMS). A cluster-wide cohort (New Territories East Cluster, NTEC) consisting of patients with history of histologically-proven gastric IM and AG will be identified and included for subsequent analysis. The data collection period for the retrospective data will be 2000-2020. Histology slides will be retrieved retrospectively when available (within NTEC). Whole slide imaging technique will be utilized for the development of training and validation cohorts with machine learning algorithms in the pathology part.
