Summary

This project aims to collect peripheral blood samples from newly diagnosed gastric cancer patients and healthy individuals. Various techniques such as cfDNA sequencing, proteomics, and fragmentomics will be employed to analyze differences in the expression of ctDNA mutations, fragmentomics, and protein biomarkers between gastric cancer patients and healthy individuals. A new comprehensive diagnostic model will be established and its diagnostic value (sensitivity, specificity, accuracy, etc.) for gastric cancer will be validated.

Specifically, the study will involve the following subjects and quantities: 700 participants from Zhejiang Cancer Hospital (350 gastric cancer patients and 350 healthy individuals), 200 participants from Sichuan Cancer Hospital (100 gastric cancer patients and 100 healthy individuals), and 200 participants from the Sixth Affiliated Hospital of Sun Yat-sen University (100 gastric cancer patients and 100 healthy individuals). Peripheral blood samples (a total of 15mL from each participant, collected in 3 tubes) will be collected from all subjects. The collected blood samples will undergo multi-omics sequencing including cfDNA methylation sequencing, proteomics, and genomics to establish a multi-omics-based early diagnostic model.
