Unequal burden of mortality from gastric cancer in Brazil and its regions, 2000–2015

Background Gastric cancer (GC) is an important cause of morbidity and mortality worldwide. However, population-based data on GC mortality dynamics in low and middle income countries are scarce. Methods We analyzed GC mortality in Brazil based on all GC-related deaths registered 2000–2015. Results A total of 17,374,134 deaths were recorded, with GC identified in 214,808 (1.24%) cases—203,941 (94.9%) as underlying cause, and 10,867 (5.1%) as associated cause of death. Adjusted rates for age and sex was 6.85 deaths/100,000 inhabitants [95% confidence interval (CI) 6.73–6.97]. The highest mortality rates were found in males [10.00; rate ratio (RR) 1.85; 95% CI 1.78–1.91; p
