What the trial is, and whether it could suit you
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.
