  1. Abbreviations: AC, adenocarcinoma not specified; DGC, diffuse-type gastric cancer; FDR, first-degree relative; IGC, intestinal-type gastric cancer; SDR, second-degree relative; TDR, third-degree relative.
  2. aOne gastric cancer diagnosed below the age of 35 years, two GC cases diagnosed in first- or second-degree relatives at or below the age of 60 years (index diagnosed at or below the age of 50 years) or three cases of GC in first- or second-degree relatives of GC diagnosed at or below 70 years of age.
