人乳头瘤病毒(HPV)在宫颈癌和喉癌的发生中起着关键作用。我们研究的目的是比较一种新的水凝胶为基础的HPV基因分型生物芯片检测(Biochip)的性能,以市售和CE标记的常规PCR,然后反向杂交(GenID-PCR)。123份样本可用于本研究。在这些样本中,101/123例为妇科拭子,8/123例为生殖器疣拭子或活检样本,7/123例为耳鼻咽喉病变活检样本,5/123例为皮肤疣样本,2/123例为口唇异常样本。这些HPV基因分型的分子方法显示出相当的灵敏度和特异性。然而,19/123的结果不一致。具体而言,生物芯片在检测多种感染方面表现出更好的性能,特别是当存在一种以上的高风险基因型时。由于两种检测方法中使用的探针配置不同,GenID-PCR只能对许多HPV基因型进行组特异性检测,而生物芯片可以进行特异性鉴定。总的来说,新开发的HPV芯片系统(生物芯片)被证明是一个合适的工具,HPV检测和基因分型;它也被证明是上级建立HPV基因分型方法。
Human papillomavirus (HPV) plays a key role in the development of cervical and laryngeal cancers. The aim of our study was to compare the performance of a new hydrogel-based HPV genotyping biochip assay (Biochip) to a commercially available and CE-marked conventional PCR followed by reverse hybridization (GenID-PCR). One hundred twenty-three samples were available for the study. Of these samples, 101/123 were gynecological swabs, 8/123 were swabs or biopsy samples of genital warts, 7/123 were biopsy samples of otorhinolaryngeal lesions, 5/123 were samples of skin warts, and 2/123 were samples of orolabial abnormalities. These molecular methods for HPV genotyping showed comparable sensitivity and specificity. However, 19/123 of the results were discrepant. Specifically, Biochip showed better performance in the detection of multiple infections, especially when more than one high-risk genotype was present. Due to the different probe configurations used in the two assays, GenID-PCR achieves only group-specific detection of many HPV genotypes, whereas Biochip allows for specific identification. Overall, the newly developed HPV chip system (Biochip) proved to be a suitable tool for HPV detection and genotyping; it also proved to be superior for establishing HPV genotyping methods.
