RECRUITINGOBSERVATIONAL
Detection of Peritoneal Metastasis of Gastric Cancer by Liquid Biopsy in Peripheral Blood: A Prospective Study
About This Trial
This study is a prospective, multi-omics, observational study aimed at detecting peritoneal metastasis of gastric cancer by combined assays for methylation of cell-free DNA (cfDNA) and other blood-based biomarkers. The study will enroll 384 participants with gastric cancer.
