Abstract

Background

Regardless of being preventable through screening strategies and prompt diagnosis, deaths from colorectal cancer (CRC) still represent a serious public health concern in Brazil, with more than 20 thousand deaths annually. Herein, we aimed to assess the temporal trends and spatiotemporal patterns of CRC mortality in all Brazilian states.

Methods

An ecological study using temporal and spatial analysis techniques on deaths due to CRC as the underlying cause in Brazil from 1980 to 2021 was conducted. Death certificate and population data were provided by the Department of Informatics of the Unified Health System (DATASUS) and by the Brazilian Institute of Geography and Statistics (IBGE), respectively.

Results

A total of 395,782 deaths from CRC were recorded in this period and most of them were in female (205,479; 51.92 %), ≥ 65 years old (233,059; 58.89 %), diagnosed with malignant neoplasm of the colon (212,277; 53.63 %), with 1–7 years of education (157.564; 39.81 %), married (192.276; 48.58 %), hospital as place of death (331.393; 83.73 %) and white (212.666; 65.07 %). Moreover, there was an increasing temporal trend in the Northeast region (APC: 2.6; p < 0.05), men (APC: 1.5; p < 0.05) and 45–64 years old (APC: 1.2; p < 0.05). Also, the spatial analysis showed positive spatial autocorrelation in all periods, with the South and Southeast regions presenting the highest concentration of high-risk clusters CRC deaths. Nevertheless, high-risk clusters were also observed in capitals and municipalities in metropolitan regions in the Northeast region.

Conclusions

In general, a temporal and spatial expansion of CRC mortality has been observed in Brazil over the last few decades.

期刊介绍： Cancer Epidemiology is dedicated to increasing understanding about cancer causes, prevention and control. The scope of the journal embraces all aspects of cancer epidemiology including: • Descriptive epidemiology • Studies of risk factors for disease initiation, development and prognosis • Screening and early detection • Prevention and control • Methodological issues The journal publishes original research articles (full length and short reports), systematic reviews and meta-analyses, editorials, commentaries and letters to the editor commenting on previously published research.
