Cancer incidence rates vary widely in Brazil. The literature on the subject for the western Amazon region is scarce. This study aimed to determine cancer incidence in the population of Rio Branco, Acre State. A total of 718 new cases were recorded during the study period. Among men, the five leading cancer sites were prostate (ASR 75.1), stomach (ASR 23.0), lung (ASR 19.1), colon and rectum (ASR 9.5), and leukemia (ASR 6.9). Among women, they were breast (ASR 41.5), cervix (ASR 41.3), lung (ASR 11.8), colon and rectum (ASR 11.0), and stomach (ASR 7.7). These indicators reveal that Rio Branco has a cancer incidence pattern that overlaps with epidemiological cancer patterns observed in developed and developing regions. The results of the study point to the importance of implementing a population-based cancer registry - currently nonexistent in Rio Branco - as a factor to promote analysis of incident cases of the disease and monitoring of its evolution.
巴西的癌症发病率差异很大。关于亚马逊西部地区的相关文献很少。本研究旨在确定阿克里州里奥布朗库市的癌症发病率。在研究期间共记录了 718 例新发病例。在男性中，五个主要的癌症部位是前列腺（ASR75.1）、胃（ASR23.0）、肺（ASR19.1）、结肠和直肠（ASR9.5）以及白血病（ASR6.9）。在女性中，这五个部位是乳房（ASR41.5）、子宫颈（ASR41.3）、肺（ASR11.8）、结肠和直肠（ASR11.0）以及胃（ASR7.7）。这些指标表明，里奥布朗库的癌症发病率模式与发达和发展中地区观察到的癌症流行病学模式重叠。该研究结果表明，建立一个基于人群的癌症登记处（目前在里奥布朗库尚不存在）非常重要，这是促进对疾病新发病例进行分析和监测其演变的一个因素。
