Abstract

Background: Almost all cases of cervical cancer are associated with persistent high-risk HPV infection. WHO prioritizes primary HPV testing for cervical cancer screening. Cervical cancer screening programs require the ability to process a large number of samples in a simple and standardized manner and obtain reliable results. The workload, time, and cost associated with the number of samples to be processed encourage the development of alternative methods to the traditional nucleic acid extraction method for population-based screening. In this study, we aimed to compare the performance of a commercial pre-denaturation solution with nucleic acid extraction in HPV DNA detection by PCR in cervical swab samples.

Methods: The study was designed in two phases: an experimental phase and a clinical phase. A total of 1200 cervical swabs were included in the clinical phase of the study. Positive results were obtained in 143 (11.9%) samples by nucleic acid extraction and 137 (11.4%) samples by PharmaDirect. Discordant results were detected in 28 (2.3%) samples.

Results: PharmaDirect provided 88.1% sensitivity compared to nucleic acid extraction. PharmaDirect provided high sensitivity for HPV genotype 16 (92.3%) and relatively limited sensitivity for mixed genotype infections (73.7%).

Conclusion: This study demonstrates the potential of an alternative commercial pre-denaturation product that does not require nucleic acid extraction for HPV DNA detection in cervical swab samples. Such approaches may represent a useful alternative for population-based screening studies.

Trial registration: Not applicable.

一种检测宫颈拭子HPV DNA的新方法:核酸提取与直接PCR的比较。
背景:几乎所有的宫颈癌病例都与持续的高危HPV感染有关。世卫组织将HPV初级检测作为宫颈癌筛查的重点。宫颈癌筛查项目需要能够以简单和标准化的方式处理大量样本,并获得可靠的结果。需要处理的样本数量所带来的工作量、时间和成本促使人们开发出替代传统核酸提取方法的方法,用于基于人群的筛查。在这项研究中,我们旨在比较商业预变性溶液与核酸提取在宫颈拭子样本中PCR检测HPV DNA的性能。方法:本研究分为两个阶段:实验阶段和临床阶段。临床阶段共纳入1200例宫颈拭子。核酸提取阳性143份(11.9%),PharmaDirect阳性137份(11.4%)。在28个(2.3%)样本中检测到不一致的结果。结果:与核酸提取相比,PharmaDirect的灵敏度为88.1%。PharmaDirect对HPV基因型16的敏感性较高(92.3%),对混合基因型感染的敏感性相对有限(73.7%)。结论:本研究证明了一种替代的商业预变性产品的潜力,该产品不需要核酸提取来检测宫颈拭子样本中的HPV DNA。这种方法可能是基于人群的筛查研究的一种有用的替代方法。试验注册:不适用。

期刊介绍: Virology Journal is an open access, peer reviewed journal that considers articles on all aspects of virology, including research on the viruses of animals, plants and microbes. The journal welcomes basic research as well as pre-clinical and clinical studies of novel diagnostic tools, vaccines and anti-viral therapies. The Editorial policy of Virology Journal is to publish all research which is assessed by peer reviewers to be a coherent and sound addition to the scientific literature, and puts less emphasis on interest levels or perceived impact.
