Cervical cancer is one of the leading causes of female death, with an annual mortality rate exceeding 200,000 in developing communities. Despite the past decade bearing witness to a reduction in cervical cancer cases throughout developed countries, the prevalence in developing countries continues to rapidly rise. The increase in cervical cancer cases is attributed to the lack of financial resources and the unavoidable risk factors of the disease. Traditional means of anticancer therapy are compromised by reduced drug potency, non-specificity, negative side effects and the development of multiple drug resistance (MDR), which leads to a decrease in the long-term anticancer therapeutic efficacy. Recent advances in nanomedicine have elucidated the potential of nanoparticles to reduce the side effects and improve the survival rate of patients, by enhancing selective delivery and uptake of photosensitive, therapeutic and genetic material to cervical cancer cells, thereby enhancing antitumour efficiency. This review paper analyses the risk factors and epidemiology of cervical cancer globally, especially in developing communities, whilst demonstrating the enhanced anticancer treatment using selected nanoparticles.
宫颈癌是女性死亡的主要原因之一,在发展中社区,其年死亡率超过20万。尽管在过去十年中,发达国家的宫颈癌病例有所减少,但发展中国家的患病率仍在迅速上升。宫颈癌病例的增加归因于缺乏财政资源以及该疾病不可避免的风险因素。传统的抗癌治疗方法受到药物效力降低、非特异性、负面副作用和多重耐药性(MDR)发展的影响,这导致长期抗癌治疗效果下降。纳米医学的最新进展阐明了纳米颗粒通过增强对宫颈癌细胞的光敏、治疗和遗传物质的选择性递送和摄取来降低副作用并提高患者存活率的潜力,从而提高抗肿瘤效率。本文综述分析了全球尤其是发展中社区宫颈癌的风险因素和流行病学,同时展示了使用选定纳米颗粒增强抗癌治疗的情况。
