OBJECTIVE To evaluate the value of visual inspection with acetic acid (VIA) test to detect high grade lesion in women with atypical squamous cells or low grade squamous intraepithelial lesions cervical cytology. METHODS Women with atypical squamous cells or low grade squamous intraepithelial lesions who were scheduled to undergo colposcopy at Vajira Hospital and met inclusion criteria were in...

Human papillomavirus (HPV) is widely accepted as a causative agent of cervical cancer. The distribution and prevalence of HPV types depend on geographic region and demographic factors. The aim of this study was to investigate the relationship between the presence of various HPV types and the outcome of cytological examination. Cervical smears were obtained from 125 women from southern Poland: l...

INTRODUCTION Before the introduction of vaccination against human papillomaviruses (HPV) as a new strategy of combating cervical cancer, it is required to describe the baseline prevalence of HPV infection as well as the distribution of the different HPV types in the population and among women with cervical lesions. MATERIALS AND METHODS Approximately 10,000 liquid cervical cell samples from w...

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 determine methylation status of nine genes, previously described to be frequently methylated in cervical cancer, in squamous intraepithelial lesions (SIL). METHODS QMSP was performed in normal cervix, low-grade (L)SIL, high-grade (H)SIL, adenocarcinomas and squamous cell cervical cancers, and in corresponding cervical scrapings. RESULTS Only CCNA1 was never methylated in norma...

BACKGROUND Human Papillomavirus (HPV) genotype distribution and co-infection occurrence was studied in cervical cytologic specimens from Murcia Region, (southeast Spain), to obtain information regarding the possible effect of the ongoing vaccination campaign against HPV16 and HPV18. METHODS A total of 458 cytologic specimens were obtained from two outpatient gynecological clinics. These inclu...

Cervical intraepithelial neoplasia grade 3 (CIN 3) is the best proxy in research and screening for invasive cancer risk. Yet the timing of CIN 3 development is uncertain because of measurement errors integral to its diagnosis. We were interested in estimating the proportions of prevalent vs incident CIN 3 within 2 years of finding a minor cytologic abnormality. We estimate that only 17 (2.8%) o...

Cervical lesion grading is critical for effective patient management. A three-tier classification (cervical intraepithelial neoplasia [CIN] grade 1, 2 or 3) based on H&E slide review is widely used. However, for reasons of considerable inter-observer variation in CIN grade assignment and for want of a biomarker validating a three-fold stratification, CAP-ASCCP LAST consensus guidelines recommen...

OBJECTIVES This study aimed to assess the relationship between infection with multiple human papillomavirus (HPV) types and abnormal anal cytology in HIV-infected men. DESIGN An observational, cross-sectional study. SETTING A regional referral hospital in Taiwan. PARTICIPANTS In total, 714 HIV-infected men were enrolled between March 2011 and June 2016. Thin preparation anal Pap smears we...

BACKGROUND The ALTS (atypical squamous cells of undetermined significance [ASCUS] and low-grade squamous intraepithelial lesion [LSIL] Triage Study) suggests that, for women diagnosed with ASCUS, human papillomavirus (HPV) DNA testing followed by referral to colposcopy of only those women with oncogenic HPV (i.e., HPV DNA testing) is as effective at detecting cervical intraepithelial neoplasia ...
