The aim of this study was to develop a methodology for estimating cancer incidence in Brazil and its regions. Using data from population-based cancer registries (RCBP, acronym in Portuguese) and the Brazilian Mortality Information System (SIM, acronym in Portuguese), annual incidence/mortality (I/M) ratios were calculated by type of cancer, age group and sex in each RCBP. Poisson longitudinal multilevel models were applied to estimate the I/M ratios by region in 2018. The estimate of new cancer cases in 2018 was calculated by applying the estimated I/M ratios to the number of SIM-corrected deaths that occurred that year. North and Northeast concentrated the lowest I/M ratios. Pancreatic, lung, liver and esophageal cancers had the lowest I/M ratios, whereas the highest were estimated for thyroid, testicular, prostate and female breast cancers. For 2018, 506,462 new cancer cases were estimated in Brazil. Female breast and prostate were the two main types of cancer in all regions. In the North and Northeast, cervical and stomach cancers stood out. Differences in the I/M ratios between regions were observed and may be related to socioeconomic development and access to health services.
本研究的目的是开发一种估算巴西及其各地区癌症发病率的方法。利用基于人群的癌症登记处（葡萄牙语缩写为RCBP）和巴西死亡信息系统（葡萄牙语缩写为SIM）的数据，在每个癌症登记处按癌症类型、年龄组和性别计算年度发病率/死亡率（I/M）比。应用泊松纵向多水平模型来估算2018年各地区的I/M比。通过将估算的I/M比应用于当年经SIM校正后的死亡人数，计算出2018年新癌症病例的估计数。北部和东北部地区的I/M比最低。胰腺癌、肺癌、肝癌和食管癌的I/M比最低，而甲状腺癌、睾丸癌、前列腺癌和女性乳腺癌的I/M比估计最高。2018年，巴西估计有506,462例新癌症病例。女性乳腺癌和前列腺癌是所有地区的两种主要癌症类型。在北部和东北部，宫颈癌和胃癌较为突出。观察到各地区之间I/M比存在差异，这可能与社会经济发展以及获得医疗服务的机会有关。
