Spatial and Temporal Distribution of Cancer Mortality in a Federative Unit of the Brazilian Legal Amazon Between 2000 and 2015
Background: About 41 million deaths were due to chronic noncommunicable diseases and of these, 9 million (22%) had cancer as a basic cause of death. In Brazil, 2,023,038 deaths from cancer occurred between 1996 and 2010. Methods: Ecological design study, in which mortality from neoplasia was analyzed, from 2000 to 2015, for the municipalities of the Mato Grosso state. Mortality rates due to cancer were calculated by the ratio of the sum of deaths by cancer in each quadrennium, divided by the
... , divided by the average of the population in the two central years of the period, multiplied by 10,000 inhabitants. An annual percentage change was calculated by the ratio of the linear regression coefficient to the cancer mortality rates in the Mato Grosso state at the beginning of the analyzed period (2000 to 2003). Thematic maps were constructed for each quadrennium using intervals of equal classes. Results: Cancer caused 31,097 deaths in the Mato Grosso state in the period, 13,058 in women and 18,039 in men, with a male to female ratio of 1.38. The top five causes of cancer death in the period were lung (12.2%), prostate (8.7%), stomach (7.7%), breast (6.0%) and liver (4.7%). There is an increase in the number of municipalities with rates greater than 23.67 deaths per 100,000 inhabitants in the period. Conclusion: The description of cancer mortality can bring important contributions to epidemiological studies. These studies are necessary, especially in Mato Grosso, since studies on this topic are scarce, and can potentially contribute to the identification of priority regions for intervention aiming to reduce mortality rates.
