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...

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...

PURPOSE Cancer of the uterine cervix is an important cause of death in women worldwide. Pap smears as a tool for screening decreased the incidence and mortality of cervical cancer dramatically. This proof of principle study aimed to develop a potential tool for cervical screening using a test that can be applied by patients without visiting a physician and to increase the coverage rate, especia...

The aim of the present study was to investigate the characteristic microRNAs (miRNAs) expressed during the pre-invasive and invasive stages of cervical cancer. A gene expression profile (GSE7803) containing 21 invasive squamous cell cervical carcinoma samples, 10 normal squamous cervical epithelium samples and seven high-grade squamous intraepithelial cervical lesion samples, was obtained from ...

BACKGROUND Although the importance of Papanicolaou (Pap) smear test screening in reducing the incidence of cervical cancer is well established, in 1994-95 one in 4 women in Manitoba aged 18 to 69 years reported never having had a Pap test or not having had a Pap test in the last 3 years. The objectives of this study were to examine the screening history of women in Manitoba diagnosed with invas...

OBJECTIVES To determine the factors that influence risk of cervical cancer after three consecutive negative Pap smears. METHODS A cohort study was conducted using data from the British Columbia Cervical Cancer Screening Program and British Columbia Cancer Registry. Analysis was based on a one percent sample of women aged 20-69 years with Pap smears enriched with all invasive cervical cancer c...

BACKGROUND Cervical cancer is the third most common cancer among women worldwide, and in Nigeria it is the second most common female cancer. Cervical cancer is an AIDS-defining cancer; however, HIV only marginally increases the risk of cervical pre-cancer and cancer. In this study, we examine the risk factors for cervical pre-cancer and cancer among HIV-positive women screened for cervical canc...

Virtually all cases of invasive cervical cancer are associated with infection by high-risk strains of human papilloma virus. Effective primary and secondary prevention programs, as well as effective treatment for early-stage invasive cancer have dramatically reduced the burden of cervical cancer in high-income countries; 85% of the mortality from cervical cancer now occurs in low- and middle-in...
