A randomised controlled trial conducted in Mumbai, India, compared invasive cervical cancer rates among women offered cervical screening with invasive cervical cancer rates among women offered no-screening. The US Office for Human Research Protections determined the Mumbai trial was unethical because informed consent was not obtained from trial participants. Reportedly, cervical screening in th...
Background: Epidemiological studies are shown robust association between human papillomavirus (HPV) and cervical cancer. From 1990 HPV was known as a necessary but insufficient cause of cervical invasive cancer. The purpose of this study was to evaluate the cost effectiveness of HPV test in cervical cancer screening. Materials and Methods: This is a systematic review article; the newest scienti...
BACKGROUND Infection with high-risk human papillomavirus (HPV) is causally related to cervical, vulvar and vaginal pre-invasive neoplasias and cancers. Highly effective vaccines against HPV types 16/18 have been available since 2006, and are currently used in many countries in combination with cervical cancer screening to control the burden of cervical cancer. We estimated the overall and age-s...
Botswana has a high burden of cervical cancer due to a limited screening program and high HIV prevalence. About 60% of the cervical cancer patients are HIV positive; most present with advanced cervical disease. Through initiatives by the Botswana Ministry of Health and various strategic partnerships, strides have been made in treatment of pre-invasive and invasive cancer. The See and Treat prog...
Cervical cancer remains an important cause of women morbidity and mortality. The progression of cervical pathology correlates with the HPV integration into the host genome. However, the data on the viral integration status in cervical dysplasias are controversial. The aim of the current study was to evaluate the status of HPV integration in two types of cervical pathology - invasive and non inv...
Allelic losses involving chromosome 3p are frequently observed in cervical cancers. Deletion mapping studies of primary cervical carcinomas have localized common regions of deletion to 3p14.2 and 3p21. The candidate tumor suppressor gene FHIT has been mapped to 3p14.2, and previous studies have demonstrated reduced or aberrant FHIT transcripts and reduced or absent Fhit protein expression in a ...
BACKGROUND Regional Cervical Screening Quality Assurance Reference Centres maintain and improve the quality of their local cervical screening programmes by monitoring standards based on a range of outcome measures. The classification of invasive cervical cancer screening histories can aid the interpretation of cervical cancer incidence trends in cervical screening services. METHODS Cervical c...
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...
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...
