简要总结
This prospective clinical observational study aims to construct a metabolite database specifically for gastric cancer patients using metabolomics technology. It seeks to develop and validate metabolic biomarkers for early diagnosis, prognosis, and prediction of recurrence and metastasis in gastric cancer, thereby a establishing safe, convenient, and highly sensitive method for early screening and prognostic prediction.

结局指标
主要结局
Disease-Free Survival
时间窗: 3 years
Disease-Free Survival (DFS) refers to the length of time after primary treatment for a disease during which the patient remains free of certain signs or symptoms of the disease. It is typically measured from the start of treatment until the first recurrence or relapse of the disease.
Overall survival
时间窗: 3 years
The time from the start of treatment to death due to any cause.
