Development and Validation of Metabolic Biomarkers for Early Diagnosis, Prognosis, and Recurrence of Gastric Cancer：MetBio-GC

Recruiting

• Conditions: Gastric Cancer

• Registration Number: NCT07076979
• Lead Sponsor: Shanghai Minimally Invasive Surgery Center

Brief Summary

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.

Study & Design

• Study Type: OBSERVATIONAL
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Disease-Free Survival	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	3 years	The time from the start of treatment to death due to any cause.

Secondary Outcome Measures

Name	Time	Method
Positive Predictive Value	3 years	The Positive Predictive Value (PPV) indicates how likely it is that a person actually has the disease if the test result is positive.
Cancer-Related Mortality	3 years
Time to Recurrence and Metastasis and Specific Sites	3 years
Distant Metastasis Rate	3 years
Negative Predictive Value	3 years	The Negative Predictive Value (NPV) indicates how likely it is that a person does not have the disease if the test result is negative.
Hazard Ratio	3 years	The hazard ratio is a measure of the relative risk of an event occurring in one group compared to another group. It is used to quantify the difference in the rate at which events occur between two groups, typically a treatment group and a control group.
Assessment of Important Metabolic Biomarkers	3 years	This outcome measure is intended to identify important metabolic biomarkers that are highly statistically associated with the prognosis of gastric cancer, such as OS, DFS, etc., given different time frames.
Recurrence Rate	3 years
