Gastric cancer (GC), a malignant disease with the highest incidence among digestive tract, is the second leading cause of cancer-related mortality worldwide (1). GC prognosis depends primarily on tumour stage. Patients with GC usually present with advanced stages of the disease at initial diagnosis, and the 5-year survival rate of these patients is significantly lower than that of patients with early diagnosis (2). Early detection and diagnosis are key to reducing GCrelated mortality, and thus, new clinical biomarkers for early tumour diagnosis, monitoring treatment response, and predicting prognosis are urgently needed.
