LATORRE S, Gonzalo et al. Coverage of diagnostic upper gastrointestinal endoscopy for the prevention of gastric cancer in Chile: results from the 2009-2010 National Health Survey. Rev. méd. Chile [online]. 2015, vol.143, n.9, pp.1198-1205. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872015000900014.

Background: In Chile, gastric cancer (GC) is a major cause of cancer related deaths. The current screening strategy consists of an upper gastrointestinal endoscopy (UGE) for people aged 40 years or more with epigastric pain. Aim: To evaluate the diagnostic coverage of the use of UGE for early detection of GC in Chile. Material and Methods: As part of the digestive module of the 2009-10 National Health Survey, 5293 adults over 15 years were asked about the presence of epigastric pain, possible upper gastrointestinal bleeding (PUGB), use of proton pump inhibitors (PPIs) or histamine H2-receptor antagonists (H2RAs), family history of GC and having performed an UGE. Results: Persistent epigastric pain was observed in 3.4% of the population. PUGB signs were observed in 3.3% of the population. The prevalence of PPIs and H2RAs use was 4.3% and 2.2% respectively, reaching 21.6% in people aged 70 years and older. Life span prevalence of UGE was 18.3%, with differences by region, health insurance and educational level. UGE coverage in people aged 40 years or older with and without persistent epigastric pain was 14.4% and 3.2% respectively (Odds ratio 4.8, p < 0.01). The prevalence of UGE was similar among people with or without PUGB or family history of CG. Conclusions: The estimated coverage of the current GC prevention strategy in Chile is 14.4%, evaluated at a population level. Further studies are required to determine the impact of this strategy on early GC diagnosis and mortality.
