Study Arms (3)

Training Group

Based on the inclusion criteria, 2000 gastric cancer patients will be recruited in the analysis. And a model will be constructed based on deep learning.

Radiation: The whole abdomen contrast-enhanced CT scanOther: H&E stained sections and slides

Internal Validation Group

Based on the inclusion criteria, 1000 gastric cancer patients will be recruited in this group to verify the sensitivity and specificity of the constructed model.

Radiation: The whole abdomen contrast-enhanced CT scanOther: H&E stained sections and slides

External Validation Group

Based on the inclusion criteria, 300 gastric cancer patients from 5 other medical centers will be recruited in this group to verify the sensitivity and specificity of the constructed model.

Radiation: The whole abdomen contrast-enhanced CT scanOther: H&E stained sections and slides

Interventions

All the participants were measured by the whole abdomen contrast-enhanced CT scan.

External Validation GroupInternal Validation GroupTraining Group

HE pathological examination was performed on all specimens of enrolled patients.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

3000 gastric cancer patients will participate in the phase I study, they will be divided into training group and internal validation group. 300 gastric cancer patients in five other medical centers will form the external validation group.
