“…As shown in Figure 1, the age-adjusted incidence rates in South Korea, Japan and China are 41.8, 29.9 and 22.7 per 100,000, respectively (compared to 3.9 per 100,000 in the US) (Ferlay et al, 2013). Gastric cancer incidence rates increase progressively with age (Crew and Neugot, 2006;Brenner et al, 2009). Gender is strongly associated with gastric cancer risk and men have markedly higher incidence rates than women (Crew and Neugot, 2006;Brenner et al, 2009;Ferlay et al, 2013).…”
