Cancer mortality in the state of Mato Grosso from 2000 to 2015: temporal trend and regional differences

Abstract

Objective: To analyze the trend of standardized rate due to mortality by cancer in the state of Mato Grosso, according to health regions, from 2000 to 2015. Methods: Ecological study of time series with data on deaths by cancer from the Mortality Information System. The rates were standardized using direct method and calculated by year and health regions. The annual percentage change (APC) and its respective confidence interval (CI 95%) were obtained through simple linear regression. Thematic maps were built to describe the rates spatial distribution. Results: There were 28,525 deaths by cancer registered in Mato Grosso and the five main causes were lung, prostate, stomach, breast and liver cancer. The highest mortality rates were found in the Médio Norte, Baixada Cuiabana and Sul Matogrossense regions. From 2000 to 2015 a growing trend was observed in the mortality rate by cancer in Mato Grosso (APC=0.81%; CI95%: 0.38; 1.26), and in four health regions, Garças Araguaia (APC=2.27%; CI95%: 1.46; 3.08), Sul Matogrossense (APC=1.12%; CI95%: 0.28; 1.97), Teles Pires (APC=1.93%; IC95%: 0,11; 3,74) and Vale dos Arinos (APC=2.61%; CI95%: 1.10; 4.70), the oter regions presented stability. Conclusion: In the state of Mato Grosso and in the four health regions there was verified a growing trend of mortality due to cancer. The results indicate the need to consider the regional differences regarding actions for cancer prevention, control and assistance.
