Abstract

Objectives: This research aims to provide concrete insight into cancer incidence, mortality, and survivorship dynamics among African women between 2016 and 2020.

Methods: The study computes the Mortality-to-Incidence Ratio (MIR) for 53 countries in Africa with available mortality and incidence data. It uses relevant Life Tables to obtain the 5-year Relative Survival rate for women in different age cohorts based on General Survival Rate and 5-year Cancer Prevalence data from the World Health Organization (WHO). The study performs an analysis of variance tests.

Results: The results of the initial data analysis show that women in the top economies in Africa have the highest cancer incidence and mortality. The study also finds that women in Northern and Southern African countries have higher relative survival rates and lower MIR than other African regions. ANOVA results confirm statistically significant differences in 5-year relative survival across the African regions. The relative survival at 5 years was an average of 45% across all age groups within the continent although relative survival is highest among females aged 5-19 and 80-84. The lowest relative survival rates are seen for infants (0-4), adolescents and young adults (25-29), and the very elderly (85+).

Conclusion: The study concludes that while cancer incidence in Africa is linked to affluence, survival is very challenging, especially for the least developed economies in Western, Eastern, and Central Africa. The results indicate the need for crucial intervention in the continent concerning awareness, research, and data collection methodology.

非洲妇女的癌症发病率、死亡率和存活率:比较分析(2016-2020 年)。
研究目的本研究旨在具体了解 2016 年至 2020 年非洲妇女的癌症发病率、死亡率和存活率动态:本研究计算了非洲 53 个国家的死亡率与发病率之比(MIR),这些国家均提供了死亡率和发病率数据。研究根据世界卫生组织(WHO)提供的一般存活率和 5 年癌症发病率数据,利用相关生命表获得不同年龄组妇女的 5 年相对存活率。研究进行了方差分析测试:初步数据分析结果表明,非洲顶级经济体的妇女癌症发病率和死亡率最高。研究还发现,与非洲其他地区相比,非洲北部和南部国家妇女的相对存活率较高,死亡率较低。方差分析结果证实,非洲各地区的 5 年相对存活率在统计上存在显著差异。非洲大陆所有年龄组的 5 年相对存活率平均为 45%,但 5-19 岁和 80-84 岁女性的相对存活率最高。婴儿(0-4 岁)、青少年和年轻成人(25-29 岁)以及高龄老人(85 岁以上)的相对存活率最低:研究得出结论,虽然非洲的癌症发病率与富裕程度有关,但存活率却非常具有挑战性,尤其是对于非洲西部、东部和中部的最不发达经济体而言。研究结果表明,有必要在非洲大陆就认识、研究和数据收集方法采取重要干预措施。
