Overview

This study aims to develop a model for predicting postoperative recurrence in patients with LAGC using artificial intelligence (AI) technology based on preoperative computed tomography (CT) images

Primary outcome measures

  • Accuracy of early recurrence models [Time frame: Immediately evaluated after the early recurrence model was built]

Eligibility criteria

Inclusion criteria

  • pathology diagnosis of LAGC (pT2NxM0-pT4NxM0);
  • radical gastrectomy with D2 lymph node dissection (>15 lymph nodes);
  • available clinicopathological data;
  • patients underwent contrast-enhanced abdominal CT scans within 4 weeks before surgery.

Exclusion criteria

  • preoperative treatment for LAGC (radiotherapy, chemotherapy, or systemic therapy);
  • previous malignancies;
  • unsatisfactory gastric distention or inability to identify the primary tumor;
  • image artifacts.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.

Healthy volunteers: No
