Cervical and prostate cancer account for 7.1 and 7.3 deaths per 100,000 people globally in 2022. These rates increased significantly to 17.6 and 17.3 in Africa, respectively, making them the second and third leading cause of cancer deaths in Africa, only surpassed by breast cancer. The human papillomavirus is the prime risk factor for cervical cancer infection. On the other hand, prostate cancer risks include ageing, genetics, race, geography, and family history. However, these factors alone cannot account for the high mortality rate in Africa, which is more than twice the global mortality rate for the two cancers. We searched PubMed, Embase, Scopus, and Web of Science to select relevant articles using keywords related to microorganisms involved in cervical and prostate cancer and the impact of poor healthcare systems on the mortality rates of these two cancers in Africa by carrying out a detailed synopsis of the studies on microbial agents involved and the contributory factors to the deteriorating healthcare system in Africa. It became apparent that the developed countries come first in terms of the prevalence of cervical and prostate cancer. However, more people per capita in Africa die from these cancers as compared to other continents. Also, microbial infections (bacterial or viral), especially sexually transmitted infections, cause inflammation, which triggers the pathogenesis and progression of these cancers among the African population; this has been linked to the region's deficient health infrastructure, making it difficult for people with microbial infections to access healthcare and hence making infection control and prevention challenging. Taken together, untreated microbial infections, primarily sexually transmitted infections due to the deficient healthcare systems in Africa, are responsible for the high mortality rate of cervical and prostate cancer.
2022年,全球范围内宫颈癌和前列腺癌的死亡率分别为每10万人中有7.1人和7.3人死亡。在非洲,这一比率分别大幅上升至17.6和17.3,使其成为非洲癌症死亡的第二和第三大主要原因,仅次于乳腺癌。人乳头瘤病毒是宫颈癌感染的主要风险因素。另一方面,前列腺癌的风险因素包括衰老、遗传、种族、地理位置和家族病史。然而,仅这些因素无法解释非洲如此高的死亡率,该地区这两种癌症的死亡率是全球死亡率的两倍多。我们检索了PubMed、Embase、Scopus和科学网,通过详细概述有关所涉及的微生物因子以及非洲医疗保健系统恶化的促成因素的研究,使用与宫颈癌和前列腺癌相关的微生物以及不良医疗保健系统对这两种癌症在非洲死亡率的影响的关键词来选择相关文章。很明显,在宫颈癌和前列腺癌的患病率方面,发达国家位居前列。然而,与其他大陆相比,非洲人均死于这些癌症的人数更多。此外,微生物感染(细菌或病毒),尤其是性传播感染,会引发炎症,从而触发非洲人群中这些癌症的发病机制和进展;这与该地区卫生基础设施不足有关,使得微生物感染患者难以获得医疗保健,因此感染控制和预防具有挑战性。综上所述,由于非洲医疗保健系统不足导致的未经治疗的微生物感染,主要是性传播感染,是宫颈癌和前列腺癌高死亡率的原因。
