The Brazilian Cervical Cancer Screening Program recommends that women are screened between ages 25 and 69 years, with cervical smears every 3 years after two consecutive negative annual smears.[1] The high-risk HPV test is not available in Brazil and the screening is opportunistic, without invitation. In 10 years it is expected that every woman will receive three to four screening examinations.[1]. This article is protected by copyright. All rights reserved.

Cervical cancer is the third most common malignant neoplasm in women worldwide. HPV infection is the necessary factor for the cancer to develop. HPV DNA can be integrated into the genome of squamous epithelium and cause transcription of the viral oncoproteins and development of invasive cancer within 15-20 years. We assessed ICC co-expression of p16/Ki-67 proteins in smears collected from the uterine cervix and the association between p16/Ki-67 co-expression and cytologic and histologic results. Samples were collected from 93 women using liquid based cytology (LBC)...

BACKGROUND: Cervical cancer is the most frequent neoplasm among Kenyan women, with 4800 diagnoses and 2400 deaths per year. One reason is an extremely low rate of screening through pap smears, at 13.8% in 2014. Knowing the costs of screening will help planners and policymakers design, implement, and scale programs. METHODS: We conducted HPV-based cervical cancer screening via self-collection in 12 communities in rural Migori County, Kenya. Six communities were randomized to community health campaigns (CHCs), and six to screening at government clinics...

OBJECTIVE: The aim of this work was to evaluate 100% rapid review (100% RR) as a useful tool to detect false negative (FN) results. STUDY DESIGN: A sample of 8,677 swabs was investigated; the unsatisfactory and negative results were referred to 100% RR, concordant results were taken as the final diagnosis, while the discordant results were debated in a consensus meeting to reach a conclusion. The positive results were examined by 2 cytologists. The data were entered into SAS statistical software, and the agreement of the 100% RR results with the final diagnosis was tested with the weighted kappa statistic...

BACKGROUND: The paradigm shift from cytological screening to Human Papillomavirus (HPV)-based screening for cervical cancer allows the introduction of new technologies in sample collection and diagnostics. The OncoE6™ Cervical Test (OncoE6 Test) is a rapid, easy-to-use lateral flow method detecting HPV16/18 E6 oncoproteins that has proven to detect high-grade cervical lesions with high specificity. If compatible with self-collection samples, this technology might allow for decentralized screening of hard-to-reach populations...

High genome copy number (viral load) of human papillomavirus (HPV) is being discussed as a risk factor for high-grade cervical lesions. However, conflicting data about the integration status or viral load of the virus as risk factors for prevalent high-grade squamous intraepithelial lesions (HSIL) are found in the literature. To investigate whether viral load and/or integration status are indicative for prevalent ASCUS/LSIL or HSIL, we determined the HPV16 viral load and the physical state of the genome in 644 women with single HPV16 infections stratified by their cytology results from a large Danish population-based cohort consisting of 40,399 women...

OBJECTIVE: Recent studies suggest an association between Human Papilloma Virus (HPV) infection, cervical inflammation and obstetric complications (i.e. spontaneous preterm parturition and cervical insufficiency). It has been proposed that viral inflammation of the placenta causes changes in the mother's immune reaction to bacterial pathogens, which leads to enhanced inflammatory reaction and preterm delivery. Therefore, the aim of this population-based study was to determine the association between abnormal cervical cytology prior to pregnancy and obstetric outcomes...

BACKGROUND: Bethesda guidelines do not require presence of transformation zone (TZ) for a cervical Pap test to be deemed adequate. However, clinicians are concerned with specimens that are reported to lack TZ. METHODS: We analyzed 566 ThinPrep cases reported as negative for intraepithelial lesion or malignancy (NILM) with no cervical abnormality detected in previous 4 years (2007-2011). These cases were divided into two cohorts; those with TZ (ETZ) and those without TZ (NTZ)...

OBJECTIVE: To determine if natural human papillomavirus (HPV) infection would induce an anamnestic response to quadrivalent (qHPV) vaccine in women with Systemic Lupus Erythematosus (SLE). METHODS: Thirty four women (19-50 years) with mild to moderate and minimally active or inactive SLE received standard qHPV vaccine. Neutralizing antibody titers to HPV 6, 11, 16 and18 were evaluated pre- and post- vaccine using HPV competitive Luminex Immunoassay. For each HPV type, logistic regressions were performed to explore the relationship between a positive titer at baseline with their final geometric mean titer and with the rise in titer...

BACKGROUND: The standard treatment for cervical adenocarcinoma in situ (AIS) is hysterectomy, which is a more aggressive treatment than that used for squamous intraepithelial lesions. Several previous studies have primarily demonstrated that the loop electrosurgical excision procedure (LEEP) is as safe and effective as cold knife cone (CKC) biopsy when AIS is unexpectedly found in a loop excision. This study evaluated the safety of LEEP as the initial treatment for patients with AIS who were strictly selected and evaluated before and after loop resection...

In most industrialized countries, screening programs for cervical cancer have shifted from cytology (Pap smear or ThinPrep) alone on clinician-obtained samples to the addition of screening for human papillomavirus (HPV), its main causative agent. For HPV testing, self-sampling instead of clinician-sampling has proven to be equally accurate, in particular for assays that use nucleic acid amplification techniques. In addition, HPV testing of self-collected samples in combination with a follow-up Pap smear in case of a positive result is more effective in detecting precancerous lesions than a Pap smear alone...

The development of the Papanicolaou smear test by Dr. George Nicholas Papanicolaou (1883-1962) is one of the most significant achievements in screening for disease and cancer prevention in history. The Papanicolaou smear has been used for screening of cervical cancer since the 1950s. The test is technically straightforward and practical and based on a simple scientific observation: malignant cells have an aberrant nuclear morphology that can be distinguished from benign cells. Here, we review the scientific understanding that has been achieved and continues to be made on the causes and consequences of abnormal nuclear morphology, the basis of Dr...
