We verified the prevalence of human papillomavirus (HPV) E6/E7 protein mRNA expression in patients with low-grade squamous intraepithelial lesions (LSILs) and negative cervicovaginal cytology. To investigate the relationship between mRNA expression and viral infection type, we assessed genotyping in single infections. Samples from 825 women were submitted to the E6/E7 survey. We noticed a large...
OBJECTIVES To compare the short-term and long-term effectiveness of human papillomavirus (HPV) tests in Norwegian Cervical Cancer Screening Programme (NCCSP). DESIGN Nationwide register-based prospective follow-up study. SETTING In 2005, the NCCSP implemented HPV testing in follow-up of unsatisfactory, atypical squamous cells of undetermined significance (ASC-US) and low-grade squamous intr...
BACKGROUND Minor cervical cytologic abnormalities include atypical squamous cells of undetermined significance (ASC-US) and low-grade squamous intraepithelial lesion (LSIL). Approximately 10-20% of women with minor cytologic abnormalities have histologic high-grade squamous intraepithelial or worse lesions (HSIL+). In Thailand, women with minor cytologic abnormalities have a relatively high ris...
Low-grade cervical squamous abnormalities (low-grade squamous intraepithelial lesions [LSIL, CIN1]) can be confused with or followed by high-grade (HSIL, CIN2/3) lesions, expending considerable resources. Recently, a cell of origin for cervical neoplasia was proposed in the squamocolumnar junction (SCJ); HSILs are almost always SCJ, but LSILs include SCJ and SCJ subsets. Abnormal cervical biops...
Objectives. In Belgium, very few studies have focused on cervical high-risk human papillomaviruses (hrHPV) prevalence and the relationship between HPV and cervical cytological abnormalities. The aim of this study was to investigate hrHPV prevalence and its relationship with cytological screening and histological results in the French-speaking community in Belgium (Brussels and Wallonia). Method...
The aim of this study was to analyse the correlation between HPV16 E6 variants and the physical status of viral genome (integrated, mixed, episomal) among patients with cervical cancer (n=40) and low-grade squamous intraepithelial lesions - LSIL (n=40). The study was performed on 80 HPV16 positive samples. HPV16 E6 variants were identified using PCR and DNA sequencing. Nucleotide sequences of E...
Cervical cytological data may not be sufficient for cervical cancer screening and prevention. In this project, we determined HPV genotype among infected Thai women with different cytological findings by characterization of E1 genes. Five hundred and thirty-five specimens were tested by PCR amplification of the E1 genes. HPV genotypes were determined by sequencing, comparison with the GenBank da...
Introduction: The human papillomavirus (HPV) is the main risk factor related to cervical cancer, the third most frequent type of cancer in Brazilian women. Early identification of high-risk HPV types in the normal cervix, or cervix with premalignant lesions may help prevent the progression of these lesions to cancer. Objective: This study aimed to detect and genotype HPV in women with low-grade...
BACKGROUND Ideally, all patients with abnormal Papanicolaou smear cytology results should undergo colposcopic examination of the cervix, but low-grade squamous intraepithelial lesions (LSILs) can also be followed up with further Papanicolaou smear surveillance. The aim of this study was to evaluate the outcome of cytologic surveillance versus immediate colposcopy in women with a cervical smear ...
conclusions this study describes robust information on the distribution of hpv genotypes among iranian women with and without cervical lesions. the present data may be of importance for designing future public health strategies, including hpv vaccination programs. results in total, hpv infection was detected in 45.4% of the cases. the most common high-risk hpv (hr-hpv) genotype was hpv-16 (32.8...
