This is the first study investigating the association between serum lncRNAs expression and H. pylori infection status with gastric cancer (GC) risk.
Significant joint effects between H19/LINC00152 expression and H. pylori infection on risk of GC were found.
A panel of three factors (H19, LINC00152 and H. pylori infection status) could distinguish GCs from controls.
Serum H19 and LINC00152 may serve as potential biomarkers for GC, particularly for those with H. pylori infection.
