Incidência, mortalidade e sobrevida do câncer de próstata em dois municípios com alto índice de desenvolvimento humano de Mato Grosso, Brasil

Abstract

To analyze the incidence, mortality and survival of prostate cancer in Cuiabá and Várzea Grande, Brazil from 2000 to 2016. Data from the Population-based Cancer Registry and the Mortality Information System were used. Mortality and incidence trends were analyzed using joinpoint regression models by age group. Survival analyses were performed using the Kaplan-Meier method, and hazard ratio was estimated by age group. From 2000 to 2016, 3,671 new cases and 892 deaths for prostate cancer were recorded. The average incidence and mortality rates were 87.96 and 20.22 per 100,000, respectively. Decreasing incidence trend was noted for all age groups from 2006 to 2016 (APC=-3.2%) and for men with 80+ years of age from 2000 to 2016 (APC=-3.0%), and increasing mortality trend for men 60-69 years of age from 2000 to 2009 (APC=3.2%). The specific five-year survival rate for prostate cancer was 79.6% (95%CI 77.2-81.9), and the rate decreased with advanced age (HR=2.43, 95%CI 1.5-3.9, for those 70 to 79 years old and HR=7.20, 95%CI 4.5-11.5, for those 80 or older). The incidence rate of prostate cancer showed a decreasing trend from 2006 for all age groups; the mortality rate was stable in that period, and worse prognosis was observed in men 70 years or older.
