Time trends in the incidence of cancer in the state of Mato Grosso, Brazil, from 2001 to 2016

Abstract The scope was to analyze the time-series trend in the incidence of cancer in the health macro-regions of the State of Mato Grosso from 2001 to 2016. It involved an ecological time-series study with data from the Mato Grosso Population-Based Cancer Registry. Age-standardized incidence rates, disaggregated by year, sex, macro-region and type of cancer, were calculated. For men, the trend was increasing for prostate cancer in the state and the Central-Northwest, East, West, and South macro-regions, and for colorectal cancer in the North; and decreasing for stomach cancer in the state and the Central-Northwest and North, for lung cancer in the East, and for esophageal cancer in the Central-Northwest. For women, the trend was increasing for breast cancer in the state from 2009 to 2016, for lung cancer in the state (2008 to 2016) and in the Central-North (2001 to 2016) and South (2007 to 2016) macro-regions; and decreasing for cervical cancer in the state and for all macro-regions, and for stomach cancer in the state and in the Central-Northwest. Colorectal cancer revealed a stable trend for the state and all macro-regions. Cancer surveillance, prevention and control actions should consider regional differences and variations in magnitude of the occurrence of the disease.
