Core Tip
Core Tip: Liquid biopsy (LB) has the potential to revolutionize cancer diagnostics, offering reduced invasiveness and improved understanding of tumor heterogeneity. Going beyond examining circulating tumor cells and cell-free DNA in blood, LB studies now explore a variety of structures and non-blood samples. Despite advancements in LB for tumor detection, prognostic assessment and treatment guidance, challenges remain, including complex and expensive techniques, lack of standardization, and suboptimal scientific evidence. In the context of gastric cancer, LB represents a promising approach, especially in advanced stages. This review navigates through LB intricacies, emphasizing its benefits while urging for future improvements to achieve clinical impact.
