Core Tip

Core tip: Despite the fact that in the last decades, gastric cancer (GC) has shown a decreasing incidence, the five-year survival rate continues to remain poor mainly because most patients are asymptomatic until the disease progresses to advanced stages. Recent progress in molecular landscape of GC and improved detection methods may facilitate screening and diagnosis of GC in early stages. Numerous studies aim to identify specific non-invasive biomarkers from alternative sources such as peripheral blood, urine or saliva, stomach wash/gastric juice. This review summarized the recently discovered circulating molecules which hold the promise to develop new strategies for early diagnosis of GC.
