BACKGROUND Human papillomavirus (HPV) is the necessary cause of cervical cancer. Published data on the epidemiology of HPV in women with invasive cervical cancer (ICC) in New Zealand (NZ) are limited. This cross-sectional study investigated the distribution of high-risk and low-risk HPV types in cervical specimens collected from women throughout NZ who had been diagnosed with ICC between 2004 a...
BACKGROUND Epidemiologic data and animal models suggest that, despite the predominant role of human papillomavirus infection, sex steroid hormones are also involved in the etiology of invasive cervical carcinoma (ICC). METHODS Ninety-nine ICC cases, 121 cervical intraepithelial neoplasia grade 3 (CIN3) cases and 2 control women matched with each case for center, age, menopausal status and blo...
BACKGROUND This study investigated the distribution of human papillomavirus (HPV) types in invasive cervical cancer (ICC), cervical intraepithelial neoplasia 2 (CIN2) and cervical intraepithelial neoplasia 3 (CIN3) in Venezuela. METHODS Paraffin-embedded samples from 329 women from 29 medical centers of the 24 states of Venezuela were analyzed to determine the distribution of HPV types for IC...
introduction : cervical screening has decreased the incidence and mortality of cervical cancer worldwide. due to a low incidence rate of cervical cancer in iran and several middle eastern countries, an opportunistic screening is available for women in this region. we aimed to design and validate a questionnaire about knowledge, attitude, and practice (kap) for cervical cancer and cervical scree...
BACKGROUND Use of oral contraceptives could increase risk of cervical cancer; however the effect of human papillomavirus (HPV), the main cause of cervical cancer, is not usually taken into account. We aimed to assess how use of oral contraceptives affected risk of cervical cancer in women who tested positive for HPV DNA. METHODS We pooled data from eight case-control studies of patients with ...
To assess the risk of prevalent high-grade cervical squamous intraepithelial lesions (HSILs) or invasive cervical cancer (ICC) associated with human immunodeficiency virus (HIV) type 1, HIV-2, and human papillomavirus (HPV) infections, HIV load, and CD4 cell count, we studied 4119 women attending an outpatient clinic in Senegal. HIV infection was associated with increased rates of cervical infe...
Background: Cervical cancer does not have symptoms in the early stages and almost all invasive carcinomas of the cervix have an earlier stage in which abnormal cells are confined to the epithelium. The intra-epithelial lesions associate with cytological features of invasive cancer. So, it is important to differentiate a cervical intraepithelial neoplasia (CIN) Ш from an invasive cervical squamo...
An accurate biomarker for the follow-up of women positive for human papillomavirus type 16 (HPV16) DNA may improve the efficiency of cervical cancer prevention. Previously, we analyzed all 113 HPV16 CpGs in cervical cytology samples and discovered differential methylation at different stages of premalignancy. In the current study, we identified a methylation biomarker consisting of a panel of 1...
We investigated the role of human leukocyte antigen (HLA) class II alleles in multistage cervical carcinogenesis. Cross-sectional analysis for HLA association with cervical cancer included 1253 Japanese women: normal cytology (NL, n = 341), cervical intraepithelial neoplasia grade 1 (CIN1, n = 505), CIN grade 2 or 3 (CIN2/3, n = 96), or invasive cervical cancer (ICC, n = 311). The HLA class II ...
A genome-wide screening study for identification of hypermethylated genes in invasive cervical cancer (ICC) was carried out to augment our previously discovered panel of three genes found to be useful for detection of ICC and its precursor neoplasia. Putatively hypermethylated and silenced genes were reactivated in four ICC cell lines by treatment with 5-aza-2'-deoxycytidine and trichostatin A ...
