Although black women experienced greater cervical cancer incidence and mortality rate reduction in recent years, they continue to have higher incidence rates than whites. Great variations also exist ...among geographic regions of the US, with the South having both the highest incidence and mortality rates compared to other regions. The present study explores the question of whether living in the South is associated with greater racial disparity in cervical cancer incidence and mortality by examining race- and region-specific rates and the trend between 2000 and 2012.
The Surveillance, Epidemiology, and End Results (SEER) 18 Program data was used. Cervical cancer incidence and mortality rates, annual percent changes, and disparity ratios were calculated using SEER*Stat software and Joinpoint regression for four groups: US14-Non-Hispanic White (NHW), US14-Non-Hispanic Black (NHB), South-NHW, and South-NHB, where South included 4 registries from Georgia and Louisiana and US14 were 14 US registries except the four South registries.
The average age-adjusted cervical cancer incidence rate was the highest among South-NHBs (11.1) and mortality rate was the highest among US14-NHBs (5.4). In 2012, the degree of racial disparities between South-NHBs and South-NHWs was greater in terms of mortality rates (NHB:NHW = 1.80:1.35) than incidence rates (NHB:NHW = 1.45:1.15). While mortality disparity ratios decreased from 2000-2012 for US14-NHB (APC: -1.9(-2.3,-1.4), mortality disparity ratios for South-NHWs (although lower than NHBs) increased compared to US14-NHW. Incidence rates for NHBs continued to increase with increasing age, whereas rates for NHWs decreased after age 40. Mortality rates for NHBs dramatically increased at age 65 compared to a relatively stable trend for NHWs. The increasing racial disparity with increasing age in terms of cervical cancer incidence rates became more pronounced when corrected for hysterectomy prevalence.
Black race and South region were associated with higher cervical cancer incidence and mortality. Cervical cancer rates uncorrected for hysterectomy may underestimate regional and racial disparities. Increasing incidence rates for older NHBs compared to NHWs warrant further research to determine whether screening should continue for NHBs over age 65.

Cervical cancer screening involves a complex process of cytology, human papillomavirus (HPV) testing, colposcopy, and a multitude of algorithms for the identification of preinvasive disease and ...prevention of invasive disease. High-risk HPV is a prerequisite for the development of almost all types of cervical cancer; therefore, a test for high-risk HPV has become an integral part of new screening strategies. Major changes to screening guidelines in the last decade include initiation of screening at age 21 years, conservative management of young women with abnormal cytology, extended screening intervals for women age ≥30 years, and cessation of screening in low-risk women at age 65 years. This review will focus on the evidence that has led to the current evidence-based guidelines. Evidence regarding primary HPV testing as well as postvaccine-based screening strategies will also be reviewed.
The dose-dense delivery of chemotherapy (greater frequency of drug delivery) was explored in women with advanced ovarian cancer. All patients received carboplatin; half received paclitaxel weekly and ...half every 3 weeks. There were no between-group differences in progression-free survival.
Ovarian cancer, the most lethal gynecologic cancer, is responsible for approximately 14,000 deaths in the United States annually.

Studies with prophylactic HPV vaccination have demonstrated impressive efficacy, immunogenicity, and safety results; however, the implementation and uptake in both low and high-income countries ...continues to be challenging. Since 2006, administration guidelines have undergone multiple updates regarding age, dosing schedule, and gender. Despite these changes, the basic tenet remains the same: prioritize immunization before initiation of sexual activity and subsequent exposure to HPV. The importance of immunizing males and females equally and the role for catch-up vaccination in late adolescent and adulthood has also been supported by subsequent research. Very recently, the FDA approved to expand the range of eligible patients for the nonavalent (9vHPV) vaccine to women and men from age 27 to 45 for the prevention of HPV-related cancers and diseases. Furthermore, members of the ACIP voted to recommend that individuals between ages 27 and 45 who have not yet been vaccinated discuss the option with their physician. This review will highlight the history of the vaccine, barriers to vaccination, current recommendations, and future directions for success.
•The HPV vaccine has been proven to be safe and effective, supported by over a decade of research.•Vaccine recommendations have undergone key changes regarding age, dosing schedule, and gender.•Guidelines have recently expanded to include recommendations for all persons up to age 45.•Higher rates of vaccine uptake are being seen in minority and lower socioeconomic status patients.•Trials are ongoing to clarify ideal dosing schedules and the possibility of a one-dose vaccine.
A group of 47 experts representing 23 professional societies, national and international health organizations, and federal agencies met in Bethesda, MD, September 14-15, 2012, to revise the 2006 ...American Society for Colposcopy and Cervical Pathology Consensus Guidelines. The group's goal was to provide revised evidence-based consensus guidelines for managing women with abnormal cervical cancer screening tests, cervical intraepithelial neoplasia (CIN) and adenocarcinoma in situ (AIS) following adoption of cervical cancer screening guidelines incorporating longer screening intervals and co-testing. In addition to literature review, data from almost 1.4 million women in the Kaiser Permanente Northern California Medical Care Plan provided evidence on risk after abnormal tests. Where data were available, guidelines prescribed similar management for women with similar risks for CIN 3, AIS, and cancer. Most prior guidelines were reaffirmed. Examples of updates include: Human papillomavirus-negative atypical squamous cells of undetermined significance results are followed with co-testing at 3 years before return to routine screening and are not sufficient for exiting women from screening at age 65 years; women aged 21-24 years need less invasive management, especially for minor abnormalities; postcolposcopy management strategies incorporate co-testing; endocervical sampling reported as CIN 1 should be managed as CIN 1; unsatisfactory cytology should be repeated in most circumstances, even when HPV results from co-testing are known, while most cases of negative cytology with absent or insufficient endocervical cells or transformation zone component can be managed without intensive follow-up.
Several studies have reported differential vaccine uptake outcomes that are associated with sociodemographic and socioeconomic characteristics, as well as provider type. However, none has examined a ...trend over a multiple-year span. In this study, we utilize a longitudinal data-based approach to examine state-level human papillomavirus (HPV) vaccine trends and their influences over time.
We analyzed National Immunization Survey - Teen data (2008-2016) to estimate HPV vaccine initiation rate in young female adolescent ages 13-17 years old among U.S. States. We identified growth patterns using the latent class growth method and explored state-level characteristics, including socioeconomic and sociodemographic attributes, and health legislation and policy-related programs among patterns.
We identified three growth patterns, which showed gradually increasing vaccination trends but different baseline HPV uptake rates (high, moderate, low). States within Pattern 1 (highest HPV vaccination rates) included the lowest percentage of families with incomes below federal poverty level, the highest percentage of bachelor's degree or higher, and the lowest number of uninsured, while states within Pattern 3 (lowest HPV vaccination rates) included families with socioeconomic attributes along the opposite end of the spectrum.
Latent class growth models are an effective tool to be able to capture health disparities in heterogeneity among states in relation to HPV vaccine uptake trajectories.
These findings might lead to designing and implementing effective interventions and changes in policies and health care coverage to promote HPV vaccination uptake for states represented under the lowest trajectory pattern.
Abstract In 2011, the American Cancer Society, the American Society for Colposcopy and Cervical Pathology, and the American Society for Clinical Pathology updated screening guidelines for the early ...detection of cervical cancer and its precursors. Recommended screening strategies were cytology and cotesting (cytology in combination with hrHPV testing). These guidelines also addressed the use of hrHPV testing alone as a primary screening approach, which was not recommended for use at that time. There is now a growing body of evidence for screening with primary hrHPV testing, including a prospective US-based registration study. Thirteen experts including representatives from the Society of Gynecologic Oncology, American Society for Colposcopy and Cervical Pathology, American College of Obstetricians and Gynecologists, American Cancer Society, American Society of Cytopathology, College of American Pathologists, and the American Society for Clinical Pathology, convened to provide interim guidance for primary hrHPV screening. This guidance panel was specifically triggered by an application to the FDA for a currently marketed HPV test to be labeled for the additional indication of primary cervical cancer screening. Guidance was based on literature review and review of data from the FDA registration study, supplemented by expert opinion. This document aims to provide information for healthcare providers who are interested in primary hrHPV testing and an overview of the potential advantages and disadvantages of this strategy for screening as well as to highlight areas in need of further investigation.
