Anal cancer has shown increasing incidence and death rates in recent years despite their lower incidence rate in the general population. Various risk factors contribute to this upward trend, with sexual risk factors playing a notable role. Additionally, there is a strong correlation between patients' survival rates and clinical outcomes with tumor stages, underscoring the importance of developing effective screening methods for anal cancer, particularly in high-risk groups. The well-established link between human papillomavirus (HPV) infection and anal tumors, combined with the success of cervical cancer screening programs, has led to some similarities in anal cancer screening strategies. However, the absence of established guidelines for anal cancer screening indicates a need for further research to assess the efficacy of these methods across different populations. Such research would enhance knowledge, awareness, and motivation for participation in screening programs. In this review, we will discuss various anal screening approaches, including their characteristics, novel biomarkers, and molecular methods, as well as prevention strategies and existing limitations in anal screening.
尽管肛管癌在普通人群中的发病率较低,但近年来其发病率和死亡率呈上升趋势。多种风险因素导致了这一上升趋势,其中性传播风险因素起着显著作用。此外,患者的生存率和临床结局与肿瘤分期之间存在密切关联,这凸显了开发有效的肛管癌筛查方法的重要性,特别是在高危人群中。人乳头瘤病毒(HPV)感染与肛管肿瘤之间已明确的联系,再加上宫颈癌筛查项目的成功,使得肛管癌筛查策略存在一些相似之处。然而,缺乏成熟的肛管癌筛查指南表明需要进一步研究,以评估这些方法在不同人群中的有效性。此类研究将增强人们对筛查项目的了解、认识和参与积极性。在本综述中,我们将讨论各种肛管筛查方法,包括其特点、新型生物标志物和分子方法,以及预防策略和肛管筛查中的现有局限性。
