Abstract (EN): Background Even though mass gastric cancer screening is controversial in Western countries, diverse strategies have been proposed in intermediate-risk to high-risk areas. Aim The aim of this study was to determine the long-term accuracy of the pepsinogen test (PG) for early diagnosis of gastric cancer. Participants and methods A cohort of inhabitants from the Northern part of Portugal, aged between 40 and 74 years (n = 5913) , subjected to the PG test (PGI <= 70 ng/ml and PGI/PGII <= 3), were followed up between November 2006 and December 2015. The diagnosis of gastric cancer was determined through linkage to the population-based registry of cancer [North Region Cancer Registry of Portugal (RORENO)]. Results Twenty-six gastric cancers were diagnosed (0.4%): nine (4%) among individuals 'positive' for the PG test (n = 225) and 15 (0.3%) among those who were 'negative' (n = 5688) [heard ratio = 12.7; 95% confidence interval (CI): 5.6-28.6]. Individuals with a 'negative PG test' had a 3-year risk of gastric cancer of 0.1%, representing a sensitivity of 35% (95% CI: 17-56%), globally, and of 58% (95% CI: 28-85%) at 3 years follow-up. The median survival rate in both groups was over 24 months. Conclusion The PG test was found to be suboptimal as a screening test and, if used (before upper gastrointestinal endoscopy), it is mandatory to repeat it after 3 years. Copyright
