What this trial studies

This observational study aims to validate an artificial intelligence system that integrates radiopathomics to predict how patients with locally advanced gastric cancer will respond to neoadjuvant chemoradiotherapy. Patients diagnosed with gastric adenocarcinoma at clinical stages II-IVa will be enrolled from multiple hospitals in Zhejiang, China. They will receive standardized neoadjuvant chemotherapy before undergoing radical surgery, with their pre-treatment imaging analyzed by the AI system to forecast postoperative tumor regression grades. The study seeks to enhance treatment decision-making through improved prediction of treatment outcomes.

Who should consider this trial

Good fit: Ideal candidates are patients diagnosed with gastric adenocarcinoma at clinical stages II-IVa without distant metastasis.

Not a fit: Patients with a history of other tumors or insufficient imaging quality will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more personalized treatment plans and improved outcomes for patients with locally advanced gastric cancer.

How similar studies have performed: While the use of AI in predicting treatment responses is gaining traction, this specific integration of radiopathomics in gastric cancer treatment is relatively novel and has not been extensively tested in prior studies.
