Safer, more convenient methods of cervical sample collection and storage are necessary to facilitate human papillomavirus (HPV) DNA testing in low-resource settings. Our study aimed to evaluate the stability of cervical specimens collected by dry swab and stored dry compared to liquid-based cytology (LBC) samples detected by HPV DNA test. Women with abnormal cytology or who were HPV positive at colposcopy were recruited from Sichuan University Huaxi the Second Hospital between October 2013 and March 2014. From each woman, physicians randomly collected cervical specimens by a swab sample placed into Sarstedt tube and a CytoBrush placed into LBC medium...

OBJECTIVE: The incidence of abnormal cervical cytology in pregnancy is similar to that reported for non-pregnant women. Furthermore, 1% of pregnant women annually screened for cervical cancer will be diagnosed with cervical intraepithelial neoplasia (CIN) of various degrees. For this reason, Pap smear should be performed in the first trimester of pregnancy. The persistence of HR-HPV infection is related to the development of CIN. However, the relationship between CIN and HR-HPV infection during pregnancy and postpartum can hardly be found...

Colposcopy with biopsy is pivotal to cervical cancer prevention programs as it is called to identify the precancerous lesions on patients that screen positive. We present a cervical cancer case from IMPROVE-COLPO, a postmarketing, multicenter, two-arm observational study on US community colposcopy that collects outcomes with the adjunctive Dynamic Spectral Imaging (DSI) in its prospective arm. A 45-year-old woman was seen for suffering of heavy periods. She had cytology of Atypical Squamous Cells of Undetermined Significance (ASC-US) and was Human Papillomavirus (HPV) positive...

BACKGROUND: Introduction of human papillomavirus-based screening is ongoing in many countries, given its higher sensitivity and longer-lasting protection compared with cytology-based screening. However, optimal clinical management of human papillomavirus-positive but cytology-negative women is unclear, and additional studies with clinical follow-up are warranted. OBJECTIVE: The aim of the current study was to investigate the long-term outcomes of the clinical management used in a double-blind, randomized clinical trial of human papillomavirus screening conducted in the context of the routine, organized screening program in Sweden...

BACKGROUND: Since most human papilloma virus (HPV) infections regress without any intervention, HPV is a necessary but may not be a solely sufficient cause of cervical intraepithelial neoplasia (CIN) and cervical cancer. Hence, the influence of cofactors on progression from cervical HPV infection to high-grade CIN and invasive cervical cancer has been a subject of intensive research. OBJECTIVE: We assessed the effect of socio-demographic and sexual reproductive factors on the prevalence of invasive cervical cancer and CIN diagnosed in cross-sectional cervical cancer screening projects carried out in seven sites of different sub-Saharan countries...

BACKGROUND: HPV DNA diagnostic tests for epidemiology monitoring (research purpose) or cervical cancer screening (clinical purpose) have often been considered separately. Women with positive Linear Array (LA) polymerase chain reaction (PCR) research test results typically are neither informed nor referred for colposcopy. Recently, a sequential testing by using Hybrid Capture 2 (HC2) HPV clinical test as a triage before genotype by LA has been adopted for monitoring HPV infections. Also, HC2 has been reported as a more feasible screening approach for cervical cancer in low-resource countries...
