About this trial
This study seeks to develop a deep-learning-based intelligent predictive model for the efficacy of neoadjuvant chemotherapy in gastric cancer patients. By utilizing the patients' CT imaging data, biopsy pathology images, and clinical information, the intelligent model will predict the post-neoadjuvant chemotherapy efficacy and prognosis, offering assistance in personalized treatment decisions for gastric cancer patients.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age 18 years or older;
Pathologically diagnosed with advanced gastric cancer in accordance with the American AJCC's TNM staging standards;
Have not undergone any systematic anti-cancer treatments before neoadjuvant chemotherapy and have not had surgery for local progression or distant metastasis;
Received standard neoadjuvant chemotherapy as recommended by the clinical guidelines, and have documented treatment details;
Disqualifiers
Patients whose CT or pathology images are unclear, making lesion assessment infeasible;
Patients diagnosed with other concurrent tumors.
Trial population
The study population comprises gastric cancer patients from various hospitals. Participants are individuals diagnosed with advanced gastric cancer and are currently undergoing neoadjuvant chemotherapy treatments. Selection is based on criteria such as age, specific diagnosis, past treatment history, and the clarity of their medical images and pathology images.

Treatments tested in this trial
Neoadjuvant Chemotherapy
DrugParticipants in this group are diagnosed with gastric cancer and are scheduled to undergo neoadjuvant chemotherapy as a part of their treatment regimen. The specific chemotherapy drugs, dosages, and schedules will be determined according to established clinical guidelines and the participant's specific condition.
Treatment groups
Trial outcomes
Primary outcomes
Area under the receiver operating characteristic curve (AUC) for TRG prediction by the AI model
The AUC will be used to evaluate the performance of the AI model in predicting TRG grading of gastric cancer patients after neoadjuvant chemotherapy. An AUC of 1 indicates perfect prediction, while an AUC of 0.5 indicates prediction no better than chance.
Accuracy of TRG prediction by the AI model
Accuracy measures the proportion of true positive and true negative predictions made by the AI model among all predictions. It indicates the capability of the model to correctly classify patients into their respective TRG gradings.
Secondary outcomes
Progression-Free Survival (PFS) at 3 years
The duration from the date of patient confirmation to the date of tumor progression or death of the patient, whichever occurs first.
Overall Survival (OS) at 5 years
The duration from the date of patient confirmation to the date of death of the patient.
