Incidence and mortality of stomach cancer in the state of Mato Grosso, Brazil, 2000-2016

Abstract

Objective: To analyze the incidence and mortality trend of stomach cancer in Grande Cuiabá, in the state of Mato Grosso, Brazil, from 2000 to 2016. Methods: Incidence information was obtained from the Population-Based Cancer Registry, and mortality information from the Mortality Information System. Crude and standardized rates were calculated using the direct method, with world population as reference. The trends were estimated by the Joinpoint regression method, according to sex and age group, and evaluated through the Annual Percent Change (APC) and Average Annual Percent Change (AAPC). The Jointpoint Regression Program software, version 4.9.0.0, was used. Results: There was a decreasing incidence trend of stomach cancer in males (AAPC= -5.2; 95%CI: -7.7;-2.6), in men aged 60 years or more (AAPC= -3 .7; 95%CI: -5.6;-1.8) and in women aged 50 to 59 years (AAPC= -5.2; 95%CI: -7.8;-2.6) and stable for the others sex and age groups. Stable mortality trend was also observed. Conclusion: Decreasing incidence trend of stomach cancer among men and, when analysed by age, among elderly males and adults and elderly females, and stable for mortality was observed. Regional information production supports the planning of local policies aimed at reducing the burden of disease and deaths, considering unequal risk conditions and access to health services.
