Cancer imposes a profound burden on low- and middle-income countries where 65% of the global cancer deaths occurred in 2020. The objective of the present review was to describe female cancer epidemiology in Brazil, barriers to prevention, screening, and treatment, and to propose strategies to a better control.
For the process of literature search and scientific acquisition, we have utilized the terms "female cancer" AND "breast cancer," AND "cervical cancer" AND "endometrial cancer" AND "ovarian cancer" AND "Brazil" in PubMed. References of the articles included in this review were manually searched in order to identify relevant studies on the topic. The official Brazilian epidemiology data were extensively analyzed at the governmental site www.inca.gov.br.
Considering cases of breast and gynecologic cancers together, 105,770 new cases are expected to be diagnosed yearly, positioning female cancer as the highest cancer incidence in Brazil. Female breast cancer is the most common and the leading cause of death from cancer in the female population in all regions of Brazil, except in the North, where cervical cancer ranks first. Cervical cancer, a preventable disease, corresponds to the third-most common neoplasia in women, with higher incidences in the North and Northeast regions of Brazil. An upward trend has been observed in endometrial cancer incidence, a tendency that follows the increase of its two most common risk factors: population aging and obesity. Ovarian cancer currently occupies the eighth position among female cancers in Brazil, but it is the most lethal gynecologic cancer. The main strategies to reduce female cancer mortality rates are the reduction of inequalities in healthcare services and the early diagnosis of cases. The lack of a specific national cancer program results in a reactive and unplanned approach to healthcare provision, ultimately leading to suboptimal resource utilization and higher expenditure.
Analyzed together, breast and gynecologic cancers correspond to the leading cause of cancer in Brazil. A heterogeneous group, female cancer includes diseases with a high primary and secondary prevention potential. The organization of a female cancer program in Brazil prioritizing primary and secondary prevention strategies, such as adequate mammography screening and human papillomavirus vaccination coverage, could significantly improve female cancer control in the country.
癌症给中低收入国家带来了沉重负担,2020 年全球 65%的癌症死亡发生在这些国家。本综述的目的是描述巴西女性癌症的流行病学情况,包括预防、筛查和治疗方面的障碍,并提出更好控制癌症的策略。
为了进行文献检索和科学获取,我们在 PubMed 中使用了“女性癌症”和“乳腺癌”、“宫颈癌”、“子宫内膜癌”、“卵巢癌”和“巴西”等术语。还手动搜索了本文综述中包含的文章的参考文献,以确定有关该主题的相关研究。巴西政府网站 www.inca.gov.br 对巴西的官方流行病学数据进行了广泛分析。
考虑到乳腺癌和妇科癌症的病例,预计每年将诊断出 105770 例新病例,使女性癌症成为巴西最高的癌症发病率。女性乳腺癌是巴西所有地区女性中最常见的癌症,也是癌症死亡的主要原因,除了北部地区,宫颈癌是女性中最常见的癌症。宫颈癌是一种可预防的疾病,在巴西的北部和东北部地区发病率较高。子宫内膜癌的发病率呈上升趋势,这一趋势与两种最常见的风险因素——人口老龄化和肥胖的增加有关。卵巢癌目前在巴西女性癌症中排名第八,但它是最致命的妇科癌症。降低女性癌症死亡率的主要策略是减少医疗服务的不平等和早期诊断病例。缺乏特定的国家癌症计划导致医疗保健提供的反应性和无计划方法,最终导致资源利用不佳和支出增加。
乳腺癌和妇科癌症一起分析,是巴西癌症的主要原因。女性癌症是一个异质群体,包括具有高度初级和二级预防潜力的疾病。在巴西组织一个女性癌症计划,优先考虑初级和二级预防策略,如适当的乳房 X 线筛查和人乳头瘤病毒疫苗接种覆盖率,可以显著改善该国女性癌症的控制。
