Abstract

Cervical cancer is a significant public health concern, disproportionately affecting women in less developed regions due to limited access to screening and vaccination programs. Despite advancements in cervical cancer prevention and treatment, there remains a need for efficient and cost-effective diagnostic tools. This study aimed to develop a multiplex real-time PCR assay to rapidly and accurately identify 15 human papillomavirus (HPV) genotypes.The primary objective was to design a screening method capable of simultaneously detecting HPV types 16 and 18, which account for over 70% of cervical cancers, as well as other clinically relevant high-risk and probable/possible high-risk. To validate the assay's performance, we compared its results with those obtained using the commercially available INNO-LiPA HPV Genotyping Extra II Assay kit (FujireBio, Tokyo, Japan). The developed assay successfully identified 15 HPV genotypes in a single reaction. Analysis of 150 positive and 40 negative clinical samples demonstrated excellent concordance between the two assays. The in-house real-time PCR test exhibited a clinical sensitivity of 98% and a clinical specificity of 100%, indicating its reliability and accuracy for HPV genotyping. The multiplex real-time PCR assay is a cost-effective and efficient tool for HPV screening, detecting multiple genotypes simultaneously. It enhances screening efficiency and accuracy, improving early detection and management of HPV-related diseases.

摘要

宫颈癌是一个重大的公共卫生问题,由于筛查和疫苗接种项目的可及性有限,对欠发达地区女性的影响尤为严重。尽管宫颈癌的预防和治疗取得了进展,但仍需要高效且具成本效益的诊断工具。本研究旨在开发一种多重实时聚合酶链反应(PCR)检测方法,以快速、准确地鉴定15种人乳头瘤病毒(HPV)基因型。主要目标是设计一种筛查方法,能够同时检测占宫颈癌病例70%以上的16型和18型HPV,以及其他临床相关的高危型和可能的高危型HPV。为验证该检测方法的性能,我们将其结果与使用市售的INNO-LiPA HPV基因分型Extra II检测试剂盒(富士瑞必欧株式会社,东京,日本)获得的结果进行了比较。所开发的检测方法在单一反应中成功鉴定出15种HPV基因型。对150份阳性和40份阴性临床样本的分析表明,两种检测方法之间具有高度一致性。内部实时PCR检测的临床敏感性为98%,临床特异性为100%,表明其在HPV基因分型方面的可靠性和准确性。多重实时PCR检测是一种具成本效益且高效的HPV筛查工具,可同时检测多种基因型。它提高了筛查效率和准确性,改善了HPV相关疾病的早期检测和管理。
