Purpose The aim of this study was to determine the risk of human papillomavirus (HPV)-related carcinomas and premalignancies in women diagnosed with cervical intraepithelial neoplasia grade 3 (CIN3). Knowledge of this risk is important to preventing the development and progression of other HPV-related premalignancies and carcinomas, by considering prophylactic HPV vaccination and/or by paying increased attention to other HPV-related carcinomas and premalignancies when CIN3 is identified. Methods Women diagnosed with a CIN3 between 1990 and 2010 were identified from the Dutch nationwide registry of histopathology and cytopathology (PALGA) and matched with a control group of women without CIN3...

OBJECTIVE: Hypermethylation of human papillomavirus (HPV) and host genes has been reported in cervical cancer. However, the degree of methylation of different HPV types relative to the severity of the cervical lesions remains controversial. Studies of the degree of methylation associated with the host gene and the HPV genome to the severity of cervical lesions are rare. We examined the association of methylation status between host genes and late gene 1 (L1) regions of HPV16, 18, 52, and 58 in cervical brushings...

The natural development of cervical cancer, which takes many years, is mostly initiated by infection with human papillomavirus (HPV) and is characterized by the development of precancerous lesions, cervical intraepithelial neoplasia 3 (CIN3), which are defined as abnormal changes in epithelial cells that cover the cervix surface. Since the pre-cancerous process is microscopic and asymptomatic, early detection is based on cytological screening, the Pap test. In Israel, Pap tests are performed based on selfreferral for testing and not within the framework of a national screening program because of the low incidence rate of cervical cancer in Israel...

High-risk human papillomavirus (HPV) testing is a recommended triage approach for females with atypical squamous cells of undetermined significance (ASCUS), but due to its poor specificity this approach is not recommended for patients with low-grade squamous intraepithelial lesions (LSIL). The objective of the current study was to determine microRNA (miR)-205 expression levels in liquid-based cytology (LBC) samples, and evaluate their ability to predict cervical intraepithelial neoplasia grade 2/3 or worse (CIN2/3+) in females with minor cytological abnormalities...

Hypermethylation of the cytosine-phosphate-guanine (CpG) sites located at the 3'-major capsid protein L1 (3'L1) and the long control region (LCR) of the human papillomavirus (HPV) genome may be associated with the progression of cervical cancer (CC). However, the methylation status of the LCR of HPV type 16 DNA remains to be elucidated in an infected Chinese population. The aim of the present study was to investigate the association between methylation of the HPV 16 L1 gene and LCR, and the severity of cervical lesions in infected female patients...

Human papillomavirus (HPV) testing has been recently introduced as an alternative to cytology for cervical cancer screening. However, since most HPV infections clear without causing clinically relevant lesions, additional triage tests are required to identify women who are at high risk of developing cancer. We performed DNA methylation profiling on formalin-fixed, paraffin-embedded tissue specimens from women with benign HPV16 infection and histologically confirmed cervical intraepithelial neoplasia grade 3 (CIN3), and cancer using a bead-based microarray covering 1,500 CpG sites in over 800 genes...

The incidence of cervical cancer (CC) in the sub-Saharan Africa region, where Nigeria is located, is amongst the highest in the world; it is estimated that 70,722 new cases of invasive cervical cancer occur annually in sub-Saharan Africa. Immunosuppression, especially due to human immunodeficiency virus (HIV) infection, is a predisposing factor for persistent infection with high-risk human papilloma virus (HR-HPV) and the development of squamous intraepithelial lesions. Four hundred and fifty women who attended the HIV clinic at the Nnamdi Azikiwe University Teaching Hospital, Nnewi, and who consented to participate in the study were randomly selected...
