چکیده

The need for accurate genotyping of human papillomavirus (HPV) infections is becoming increasingly important, since (i) the oncogenic potential among the high-risk HPV genotypes varies in the pathogenesis of cervical cancer, (ii) monitoring multivalent HPV vaccines is essential to investigate the efficiency of the vaccines, and (iii) genotyping is crucial in epidemiologic studies evaluating HPV infections worldwide. Various genotyping assays have been developed to meet this demand. Comparison of different studies that use various HPV genotyping tests is possible only after a performance assessment of the different assays. In the present study, the SPF(10) LiPA version 1 and the recently launched Roche Linear Array HPV genotyping assays are compared. A total of 573 liquid-based cytology samples were tested for the presence of HPV by a DNA enzyme immunoassay; 210 were found to be positive for HPV DNA and were evaluated using both genotyping assays (163 with normal cytology, 22 with atypical squamous cells of undetermined significance, 20 with mild/moderate dysplasia, and 5 with severe dysplasia). Comparison analysis was limited to the HPV genotype probes common to both assays. Of the 160 samples used for comparison analysis, 129 (80.6%) showed absolute agreement between the assays (concordant), 18 (11.2%) showed correspondence for some but not all genotypes detected on both strips (compatible), and the remaining 13 (8.2%) samples did not show any similarity between the tests (discordant). The overall intertest comparison agreement for all individually detectable genotypes was considered very good (kappa value, 0.79). The genotyping assays were therefore highly comparable and reproducible.

comparison of two commercial assays for detection of human papillomavirus (HPV) in cervical scrape specimens: validation of the Roche AMPLICOR HPV test as a means to screen for HPV genotypes associated with a higher risk of cervical disorders.

Certain high-risk (HR) human papillomavirus (HPV) types are a necessary cause for the development of cervical disorders. Women with persistent HR HPV infections have an increased risk of developing high-grade cervical lesions, compared with those who have no or low-risk HPV infections. Therefore, implementation of HPV detection into cervical screening programs might identify women at risk of ce...

Detection of HPV DNA in paraffin-embedded cervical samples: a comparison of four genotyping methods

BACKGROUND Identification of human papillomavirus (HPV) DNA in cervical tissue is important for understanding cervical carcinogenesis and for evaluating cervical cancer prevention approaches. However, HPV genotyping using formalin-fixed, paraffin-embedded (FFPE) tissues is technically challenging. We evaluated the performance of four commonly used genotyping methods on FFPE cervical specimens c...

A real-time PCR approach based on SPF10 primers and the INNO-LiPA HPV Genotyping Extra assay for the detection and typing of human papillomavirus.

The SPF10 PCR targets a conserved 65bp region of the HPV L1 gene for broad-spectrum amplification. The LiPA assay allows subsequent genotyping of the HPV amplicons. This study aims to develop a SPF10 real-time PCR to achieve simultaneous amplification and detection of the HPV target. That way, LiPA analysis of the HPV-negative samples can be avoided, reducing workload and cost. The real-time PC...
