Incidence trend of five main causes of cancer, in Grande Cuiabá, Mato Grosso, Brazil, 2000 to 2016

Abstract

Objective: To analyze the incidence trend of the five main causes of cancer, according to sex and age, in Grande Cuiabá, in the state of Mato Grosso, from 2000 to 2016. Methods: Incidence information was obtained from the Population-Based Cancer Registry, referring to the municipalities Cuiabá and Várzea Grande (RCBP - Cuiabá). Crude incidence rates were calculated and the five main types of cancer were selected: for males, prostate (C61), lung (C33-34), colorectal (C18-21), stomach (C16) and oral cavity (C00- 10) and for females, breast (C50), cervix (C53), colorectal (C18-21), lung (C33-34) and thyroid gland (C73). Age-standardized rates were calculated by the direct method, using the world population as reference. Trends were estimated using the Joinpoint method and evaluated by Annual Percent Change (APC) and Average Annual Percent Change (AAPC). The Jointpoint Regression Program software, version 8.3.6.1, was used. Results: During the period, there was a decreasing trend of lung cancer (AAPC= -2.2; 95%CI: -4.0;-0.3) and stomach (AAPC= -5.2; 95%CI: -7.7;-2.6), in men, and cervix (AAPC= -7.2; 95%CI: -9.0;-5.3), in women, and increasing for breast (AAPC= 2.8; 95%CI: 0.2;5.5) and thyroid (AAPC= 8.3; 95%CI: 4.6;12.2). Conclusion: In Grande Cuiabá, decreasing incidence trend among elderly men for prostate, lung and stomach were observed. Women are affected at younger age groups, with increasing trend for breast and decreasing for cervix cancer.
