Cervical cancer, the second most common cancer in women, develops through well-defined precursor lesions with potential to progress to invasive disease if not properly detected and eradicated. In cervical carcinogenesis, human papillomavirus (HPV) plays an important causal role. Besides the evidental causal role in cervical carcinogenesis, HPV is an important prognostic factor for disease progr...

PURPOSE To identify the presence of Human Papilloma Virus (HPV) infection and evaluate the role of Highly Active Antiretroviral Treatment (HAART) in patients with HIV-HPV co-infection. We also compared cytological screening results with HPV-DNA detection to implement screening programs and prevention of invasive cervical cancer (ICC) in HIV-infected females. PATIENTS AND METHODS We enrolled H...

OBJECTIVES To investigate the risks of invasive cervical cancer after detection of atypical glandular cells (AGC) during cervical screening. DESIGN Nationwide population based cohort study. SETTING Cancer and population registries in Sweden. PARTICIPANTS 3,054,328 women living in Sweden at any time between 1 January 1980 and 1 July 2011 who had any record of cervical cytological testing a...

Cervical cancer develops through progression from normal cervical epithelium through squamous intraepithelial lesions (SIL) to invasive cancer. Cervical cancer is associated with oncogenic human papillomavirus (HPV). The HPV E6 oncoprotein binds to the tumor suppressor gene product p53, promoting its degradation; the Arg allele of p53 Arg72Pro polymorphism binds more ardently with HPV E6 than t...

Cervical cancer is a significant gynaecological cancer in women, and is preventable by regular screening using the Papanicolaou technique. Screening identifies precancerous lesions that convey a risk of invasive cancer. These lesions can be removed which reduces the population incidence of cervical cancer (primary prevention). Screening can also detect early asymptomatic invasive cancer and thu...

Aim: To assess the clinical significance of hTERC amplification for cervical cancer screening detected by fluorescence in situ hybridization (FISH) and compare it with that of current screening methods within the same group. Methods: A total of one hundred and nine women were recruited in this study. All of them had liquid-based thin-prep cytologic test (TCT), human papillomavirus (HPV) DNA tes...

In recent decades, several Western countries have reported an increase in oropharyngeal and anal cancers caused by human papillomavirus (HPV). Trends in HPV-associated cancers in Asia have not been as well described. We describe the epidemiology of potentially HPV-related cancers reported to the Singapore Cancer Registry from 1968-2012. Analysis included 998 oropharyngeal squamous cell carcinom...

BACKGROUND Many physicians advocate repeat surgery after cervical conization with a diagnosis of cervical cancer stage FIGO IA1. In a multicenter trial, whether repeat surgery is a necessary therapeutic procedure in the treatment of cervical cancer stage FIGO IA1 was evaluated and a literature review performed. PATIENTS AND METHODS From 1997 to 2006, 156 patients with squamous cell cervical c...

In the present study, our aim was to investigate whether EBV DNA could be found in association with invasive and pre-invasive cervical cancer lesions. We hypothesize that EBV is not merely a commensal agent when present in malignant cervical lesions. DNA was extracted from cervical scrapings followed by nested PCR-based amplification. The patients were 66 women with high grade cervical intraepi...

OBJECTIVE Previous studies have demonstrated that levels of hypermethylation of paired boxed gene 1 in cervical tissues are associated with the grades of severities of cervical neoplasia in women, which suggests that testing for DNA methylation has a potential role in neoplasma screening. In this study, by testing methylation levels of PAX1 genes in cervical scrapings and cervical tissues of di...
