Abstract
OBJECTIVE The objective of this study was to evaluate trends in prevalence of cervical cancer (CC) and rates of recurrent or metastatic cervical cancer (r/mCC) treatment initiation at the state and metropolitan statistical area (MSA) levels among Medicaid enrolled females from 2016 to 2019. METHODS Retrospective analyses of nationwide Medicaid claims data were used to identify adult CC and r/mCC patients from 2016 to 2019. CC prevalence was estimated as the proportion of females diagnosed with CC out of all adult female Medicaid beneficiaries, and r/mCC by the proportion of CC patients who initiated a systemic treatment not associated with surgery or radiation to the number of enrollees with CC diagnosis in each state or MSA. Overall and annual rates were calculated for each state and MSA from 2016 to 2019. RESULTS The analytic cohort included 70,865 adult female Medicaid beneficiaries with CC from 2016 to 2019, among whom 3375 were identified as r/mCC patients. Nationwide annual prevalence of CC remained relatively stable from 2016 to 2019, while r/mCC decreased slightly over the study period. Several MSAs experienced increasing rates of r/mCC from 2016 to 2019, including Mayaguez, PR, Aguadeilla-Isabela, PR, and Green Bay, WI. CONCLUSIONS Claims data demonstrate areas in the United States with disproportionately high or increasing CC or r/mCC burden, indicating a potential gap in preventative care for females and an unmet need for education and health care resource allocation. Future research should evaluate associations between community-level factors and r/mCC burden.

Examining the association of clinician characteristics with perceived changes in cervical cancer screening and colposcopy practice during the COVID-19 pandemic: a mixed methods assessment. eLife 2023; 12:e85682.

Abstract
Background The COVID-19 pandemic led to reductions in cervical cancer screening and colposcopy. Therefore, in this mixed method study we explored perceived pandemic-related practice changes to cervical cancer screenings and colposcopies. Methods In 2021, a national sample of 1251 clinicians completed surveys, including 675 clinicians who performed colposcopy; a subset (n=55) of clinicians completed qualitative interviews. Results Nearly half of all clinicians reported they were currently performing fewer cervical cancer screenings (47%) and colposcopies (44% of those who perform the procedure) than before the pandemic. About one-fifth (18.6%) of colposcopists reported performing fewer LEEPs than prior to the pandemic. Binomial regression analyses indicated that older, as well as internal medicine and family medicine clinicians (compared to OB-GYNs), and those practicing in community health centers (compared to private practice) had higher odds of reporting reduced screening. Among colposcopists, internal medicine physicians and those practicing in community health centers had higher odds of reporting reduced colposcopies. Qualitative interviews highlighted pandemic-related care disruptions and lack of tracking systems to identify overdue screenings. Conclusions Reductions in cervical cancer screening and colposcopy among nearly half of clinicians more than 1 year into the pandemic raise concerns that inadequate screening and follow-up will lead to future increases in preventable cancers. Funding This study was funded by the American Cancer Society, who had no role in the study's design, conduct, or reporting.

Abstract
BACKGROUND We evaluated cervical cancer program for women living with HIV (WLHIV) to determine program screening rate, primary case finder screening accuracy and treatment and post-treatment screening rate among screen-positive patients. METHODS A ten-month review of cervical cancer program data among WLHIV aged 15-49 years on HIV care across forty-one comprehensive ART sites, supported by APIN (a PEPFAR implementing partner) for cervical cancer screening and treatment in Nigeria, was conducted from October 2020 to July 2021. Initial screening was done using visual inspection with acetic acid (VIA) followed by a gynaecologist expert review through a program-designed software named AVIVA, as a confirmatory test. Associations were measured between the primary case finder screening accuracy and study covariates at p-value of 0.05. RESULTS About 10,289 asymptomatic women aged 15-49 years living with HIV were screened for cervical cancer by primary case finders using VIA-based screening test. About 732 (7.1%) had a positive screening test suggestive of precancerous lesions or cervical cancer. Three hundred and fifteen (43.0%) of VIA positive women had treatment using thermal ablation and less than one-third (21.6%) of those treated came back for post-treatment screening test. Primary case finder screening sensitivity, specificity, positive predictive and negative predictive accuracy using gynaecologist review as confirmatory test were 60.8%, 71.5%, 41.7% and 84.5% respectively. Overall screening accuracy was 68.8%. CONCLUSION AND RECOMMENDATIONS This innovative approach to cervical cancer screening among WLHIV yielded modest results in preventing program error and wastages. Wider deployment of expert-based reviews of VIA though AVIVA software might be a veritable approach to improve screening accuracy in low resource settings.

Cervical cancer geographical burden analyzer: An interactive, open-access tool for understanding geographical disease burden in patients with recurrent or metastatic cervical cancer. Gynecol Oncol 2023; 169:113-117. [PMID: 36549175 DOI: 10.1016/j.ygyno.2022.12.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 12/02/2022] [Accepted: 12/08/2022] [Indexed: 12/24/2022]
Abstract
OBJECTIVE Cervical cancer (CC) disproportionately affects women based on socioeconomic status and racial/ethnic background. There is limited research in quantifying and visualizing whether substantial geographical disparities in the US exist with respect to CC burden, and especially with respect to recurrent or metastatic CC (r/mCC) disease burden. Identifying regions with higher r/mCC burden may help inform effective healthcare resource allocation and navigating patients to appropriate care. METHODS We conducted a retrospective analysis of the 2015-2020 MarketScan® Commercial and Supplemental Medicare claims data; r/mCC burden was estimated as the number of patients initiating r/mCC systemic therapy over CC-diagnosed patients for each of the 410 metropolitan statistical areas (MSAs) considered. We developed a public, web-based tool, the Cervical Cancer Geographical Disease Burden Analyzer (Cervical Cancer Geo-Analyzer, http://www.geo-analyzer.org), that allows users to visualize r/mCC burden across MSAs over multiple years. RESULTS There was considerable variation in r/mCC burden across MSAs, with a range of 0-83.3%. Burden increased in Boston-Cambridge-Newton, MA (r/mCC to CC ratio: 41% in 2018 to 50% in 2020), and Sacramento-Roseville-Arden-Arcade, CA (33% in 2018 to 50% in 2020). On the other hand, while r/mCC burden remained high, it decreased in Grand Rapids, MI (55% in 2018 to 31% in 2020) and San Francisco-Oakland-Hayward, CA (40% in 2018 to 26% in 2020). There were regions with sparse or no data, suggesting a need for more representative data capture. CONCLUSION The Cervical Geo-Analyzer is a tool to visualize areas with high need for CC interventions. It also builds the foundation for further work to understand local risk factors of disease burden, identify populations of interest, characterize health disparities of CC or r/mCC and inform targeted interventions.

Abstract
We performed a systematic review and meta-analysis to evaluate the accuracy of screening cervical cancer tests as alternative standalone methods. The combined estimates of sensitivity of visual inspection with acetic acid, visual inspection with lugol's iodine, conventional pap smear, liquid-based cytology, High risk HPV testing by clinician, High risk HPV testing by self- sampling, cervicography were 64%, 80%, 55%, 70%, 70% and 67% respectively; the combine values of specificity of these screening strategies were 88%, 88%, 96%, 59%, 94%, and 95% respectively. Our findings draw attention to an attractive opinion to facilitate the collection of specimens for DNA HPV by patients in settings where they don't have access to a regular screening programs.

Abstract
Cervical cancer is preventable through HPV vaccination and screening however, uptake falls below national targets. A scoping review was conducted to describe stigmas related to HPV infection and vaccination and cervical cancer and screening in the US. Results were organized into the domains proposed by Stangl and colleagues' Health Stigma and Discrimination Framework. Common drivers of stigma were fear of social judgement and rejection, self-blame, and shame. Positive facilitators included social norms that provided motivation to receive HPV vaccination and screening. Gender and social norms were notable negative facilitators of stigma. HPV infection and cervical cancer resulted in stigma marking through the belief that both result from incautious behavior-either multiple sexual partners or failing to get screening. Stereotyping and prejudice were stigma practices attributed to HPV infection and cervical cancer through these same behaviors. Stigma experiences related to HPV infection, cervical cancer, and abnormal screening results included altered self-image based on perceived/anticipated stigma, as well as discrimination. This review advances understanding of the multiple dimensions of stigma associated with these outcomes in the US population. Three areas warrant additional consideration. Future studies should 1) assess how stigma dimensions affect uptake of cervical cancer preventions efforts; 2) focus on US women most affected by cervical cancer incidence and mortality to identify potential differences in these dimensions and tailor interventions accordingly; 3) include women from geographic areas of the US with high rates of cervical cancer to adapt interventions that address potential regional variations in resources and need.

Abstract
BACKGROUND Near elimination of cervical cancer in the United States is possible in coming decades, yet inequities will delay this achievement for some populations. We sought to explore the effects of human papillomavirus (HPV) vaccination on disparities in cervical cancer incidence between high- and low-poverty U.S. counties. METHODS We calibrated a dynamic simulation model of HPV infection to reflect average counties in the highest and lowest quartile of poverty (percent of population below federal poverty level), incorporating data on HPV prevalence, cervical cancer screening, and HPV vaccination. We projected cervical cancer incidence through 2070, estimated absolute and relative disparities in incident cervical cancer for high- versus low-poverty counties, and compared incidence with the near-elimination target (4 cases/100,000 women annually). RESULTS We estimated that, on average, low-poverty counties will achieve near-elimination targets 14 years earlier than high-poverty counties (2029 vs. 2043). Absolute disparities by county poverty will decrease, but relative differences are estimated to increase. We estimate 21,604 cumulative excess cervical cancer cases in high-poverty counties over the next 50 years. Increasing HPV vaccine coverage nationally to the Healthy People 2020 goal (80%) would reduce excess cancer cases, but not alter estimated time to reach the near-elimination threshold. CONCLUSIONS High-poverty U.S. counties will likely be delayed in achieving near-elimination targets for cervical cancer and as a result will experience thousands of potentially preventable cancers. IMPACT Alongside vaccination efforts, it is important to address the role of social determinants and health care access in driving persistent inequities by area poverty.

Abstract
BACKGROUND Disparities in invasive cervical cancer (ICC) incidence exist globally, particularly in HIV positive women who are at elevated risk compared to HIV negative women. We aimed to determine the spatial, temporal, and spatiotemporal incidence of ICC and the potential risk factors among HIV positive women in South Africa. METHODS We included ICC cases in women diagnosed with HIV from the South African HIV cancer match study during 2004-2014. We used the Thembisa model, a mathematical model of the South African HIV epidemic to estimate women diagnosed with HIV per municipality, age group and calendar year. We fitted Bayesian hierarchical models, using a reparameterization of the Besag-York-Mollié to capture spatial autocorrelation, to estimate the spatiotemporal distribution of ICC incidence among women diagnosed with HIV. We also examined the association of deprivation, access to health (using the number of health facilities per municipality) and urbanicity with ICC incidence. We corrected our estimates to account for ICC case underascertainment, missing data and data errors. RESULTS We included 17,821 ICC cases and demonstrated a decreasing trend in ICC incidence, from 306 to 312 in 2004 and from 160 to 191 in 2014 per 100,000 person-years across all municipalities and corrections. The spatial relative rate (RR) ranged from 0.27 to 4.43 in the model without any covariates. In the model adjusting for covariates, the most affluent municipalities had a RR of 3.18 (95% Credible Interval 1.82, 5.57) compared to the least affluent ones, and municipalities with better access to health care had a RR of 1.52 (1.03, 2.27) compared to municipalities with worse access to health. CONCLUSIONS The results show an increased incidence of cervical cancer in affluent municipalities and in those with more health facilities. This is likely driven by better access to health care in more affluent areas. More efforts should be made to ensure equitable access to health services, including mitigating physical barriers, such as transportation to health centres and strengthening of screening programmes.

Abstract
Objective The purpose of this study was to identify racial disparities in treatment outcomes, if any, among patients with carcinoma of the cervix treated at a tertiary care institution in the state of Mississippi. Methods A retrospective review of patients with carcinoma of the cervix treated in the Department of Radiation Oncology at our institution between 2010 and 2018 was performed. Data regarding demographics, disease stage, treatments administered, and follow-up were collected. Patient outcomes, including median survival and overall survival, were analyzed using the Kaplan-Meier method. All analyses were performed using SPSS Statistics version 24 (IBM, Armonk, NY). Results Between January 2010 and December 2018, a total of 165 patients with carcinoma of the cervix were treated at our institution. We had a significantly higher proportion of African American (AA) compared to Caucasian American (CA) patients (59.4 vs. 36.4%; p=0.03). There was a significant difference in the disease stage at the time of presentation between AA and CA in that compared to AA women, a higher number of CA patients presented with locally advanced disease [Federation of Gynecology and Obstetrics (FIGO) stages IB2 to IVA] (78.6 vs. 86.7%; p<0.001). However, a higher number of AA patients presented with metastatic disease at diagnosis compared to CA women (13.3 vs. 8.3%; p<0.001). Regarding their treatment, 157 (95.2%) underwent definitive chemoradiotherapy, while three (1.8%) had definitive surgery followed by adjuvant radiation or chemoradiation, depending on the risk factors identified operatively. The treatment details of five patients were not available. The median follow-up and the median survival of the entire cohort were 16 months and 79 months, respectively. In our cohort, there was no significant difference in overall survival between AA and CA patients at either three years (80 vs. 68%; p=0.883) or five years (77 vs. 68%; p=0.883). As expected, patients with locally advanced disease showed a significantly better median survival of 79 months compared to only 11 months for those with metastatic disease at their presentation (p<0.001). Conclusions Our study revealed that more AA women presented with metastatic disease compared to CA women. However, our analysis did not identify any racial disparities in the prognosis of the entire cohort.

Abstract
A novel 3-tiered grading system that combines tumor budding activity and cell nest size has been found to be highly prognostic in squamous cell carcinomas (SCCs) of various sites, including lung, oral cavity, larynx, hypopharynx, and esophagus. A similar grading system has recently been proposed for SCC of the uterine cervix. In this study, we appraise this grading system in an institutional cohort of cervical SCC to assess its prognostic value in an independent dataset. Our study cohort consisted of 94 consecutive, surgically excised, neoadjuvant therapy-naive cases of SCC of the uterine cervix, stage pT1b or higher. Tumor budding activity and cell nest size were scored on each case, the sum of which formed the basis for assigning a grade in the 3-tiered grading system hereafter referred to as the "tumor budding/nest size" (TBNS) system. As individual variables, both high tumor budding and small nest size were each associated with reduced overall survival (OS), disease-specific survival, and disease-free survival. The full TBNS system was associated with decreased OS, disease-specific survival, and disease-free survival independent of patient age, pathologic stage, and regional lymph node status. TBNS grades 1, 2, and 3 subgroups were clearly distinguishable on multivariate analyses (hazard ratio for OS of 2.06 [95% confidence interval: 0.5-8.42] for grade 2 and 4.58 [95% confidence interval: 1.24-16.87] for grade 3 tumors, relative to their grade 1 counterparts [P=0.035]). Higher grade tumors in the TBNS system were significantly correlated with advanced pathologic stage and lymph node metastasis (P=0.044 and 0.04, respectively). Among the other, potentially prognostic factors, higher pathologic stage, and lymph node metastasis were associated with decreased OS (P<0.001 and 0.004, respectively), whereas keratinization, nuclear size, mitotic count, and World Health Organization (WHO) grade were not. In conclusion, the proposed TBNS grading system is an excellent prognostic indicator that may potentially provide information that is useful in clinical decision-making. Our findings validate the previous study that proposed this system for prognostically stratifying cervical SCC patients. If further confirmed, consideration should be given to routinely adding a TBNS grade to pathologic descriptions of cervical SCC.

Abstract
BACKGROUND Black women face cervical cancer disparities with higher rates of morbidity and mortality compared with White women. Identifying predictors of Papanicolaou (Pap) testing is a first step to decrease morbidity and mortality from cervical cancer, with barriers and self-efficacy being constructs that should be related to Pap testing adherence. Although barriers and self-efficacy scales have been developed, they have not been validated in Black women for Pap testing. OBJECTIVE The purpose of this study was to modify and psychometrically test barriers and self-efficacy to Pap testing in a Black population. INTERVENTION/METHODS Data were collected from a minority health fair. Internal consistency reliability testing was conducted using item analysis and Cronbach's α. Construct validity was assessed by exploratory factor analysis and logistic regression. Papanicolaou testing adherence was regressed on each scale (barriers and self-efficacy) while controlling for antecedents. RESULTS Data demonstrated 2 reliable scales: (1) barriers (Cronbach's α = .79), item-total correlation = 0.479 to 0.628; and (2) self-efficacy (Cronbach's α = .85), item-total correlation = 0.560 to 0.697. Exploratory factor analysis supported 2 unidimensional scales. The regression models supported a relationship between each scale and Pap testing adherence. CONCLUSIONS The data suggested barriers and self-efficacy scales were reliable and valid among Black women. Barriers and self-efficacy could be tailored in future interventions to increase Pap testing adherence. IMPLICATIONS FOR PRACTICE Nurses could use responses to these scales for framing discussions about Pap testing.

Abstract
Background: Approximately one-half of cervical cancer cases in the United States occur in underscreened or never-screened women. We examined predictors to completing Papanicolaou (Pap) testing and whether a positive human papillomavirus (HPV) self-collection result affects Pap testing adherence among underscreened women. Materials and Methods: Low-income women aged 30-65 years who reported no Pap testing in ≥4 years were recruited in North Carolina. Knowledge, attitudes, and barriers regarding cervical cancer and Pap testing were assessed by telephone questionnaires. We mailed self-collection kits for HPV testing and provided information regarding where to obtain affordable Pap testing. Participants received $45 for completing all activities. We used multivariable logistic regression to assess the predictors of longer reported time since last Pap (≥10 vs. 4-9 years) and of completion of Pap testing following study enrollment (follow-up Pap). Results: Participants (n = 230) were primarily black (55%), uninsured (64%), and with ≤high school education (59%). Cost and finding an affordable clinic were the most commonly reported barriers to screening. White women and those with ≤high school education reported longer intervals since last Pap test. Half of the participants reported completing a follow-up Pap test (55%). Women with a positive HPV self-collection were five times more likely to report completing a follow-up Pap test than those with negative self-collection (odds ratio = 5.1, 95% confidence interval 1.4-25.7). Conclusions: Improving awareness of resources for affordable screening could increase cervical cancer screening in underserved women. Home-based HPV self-collection represents an opportunity to re-engage infrequently screened women into preventive screening services.

Abstract
In the United States, African American/black individuals bear a disproportionate share of the cancer burden, having the highest death rate and the lowest survival rate of any racial or ethnic group for most cancers. To monitor progress in reducing these inequalities, every 3 years the American Cancer Society provides the estimated number of new cancer cases and deaths for blacks in the United States and the most recent data on cancer incidence, mortality, survival, screening, and risk factors using data from the National Cancer Institute, the North American Association of Central Cancer Registries, and the National Center for Health Statistics. In 2019, approximately 202,260 new cases of cancer and 73,030 cancer deaths are expected to occur among blacks in the United States. During 2006 through 2015, the overall cancer incidence rate decreased faster in black men than in white men (2.4% vs 1.7% per year), largely due to the more rapid decline in lung cancer. In contrast, the overall cancer incidence rate was stable in black women (compared with a slight increase in white women), reflecting increasing rates for cancers of the breast, uterine corpus, and pancreas juxtaposed with declining trends for cancers of the lung and colorectum. Overall cancer death rates declined faster in blacks than whites among both males (2.6% vs 1.6% per year) and females (1.5% vs 1.3% per year), largely driven by greater declines for cancers of the lung, colorectum, and prostate. Consequently, the excess risk of overall cancer death in blacks compared with whites dropped from 47% in 1990 to 19% in 2016 in men and from 19% in 1990 to 13% in 2016 in women. Moreover, the black-white cancer disparity has been nearly eliminated in men <50 years and women ≥70 years. Twenty-five years of continuous declines in the cancer death rate among black individuals translates to more than 462,000 fewer cancer deaths. Continued progress in reducing disparities will require expanding access to high-quality prevention, early detection, and treatment for all Americans.

Abstract
OBJECTIVES Despite screening, disparities exist in cervical cancer incidence and outcomes. Demographic factors are associated with diagnosis at advanced stage (AS), but less is known about geographic factors. We sought to investigate risk factors for developing AS cervical cancer in Alabama. MATERIALS AND METHODS We identified women treated for cervical cancer from 2005 to 2015 at our institution. Stages II-IV were considered AS. ZIP codes were categorized by federal Rural-Urban Commuting Area Codes, and 16 historically underserved counties were categorized as Black Belt rural. Using data from the American College of Obstetricians and Gynecologists, we identified women's health provider locations. We explored associations between stage and multiple factors using logistic regression. RESULTS Of 934 patients, 29.2% were black, 52.7% had AS cancer, and 63.4% lived in urban areas. Average distance to nearest American College of Obstetricians and Gynecologists Fellow in urban, rural, and Black Belt rural areas was 5.0, 10.6, and 13.7 miles, respectively. Black race, public insurance and age of older than 65 years were associated with increased risk of AS cancer. Living in a rural area trended toward higher risk but was not significant. When stratified by race, insurance status and age were associated with AS cancer in white women only. CONCLUSIONS Living further from a women's health provider or in a rural area was not associated with a higher risk of AS cervical cancer. Black women had a higher risk of AS than white women regardless of age, insurance status, and geography. Disparities in cervical cancer are multifactorial and necessitate further research into socioeconomic, biologic, and systems causes.

Abstract
Church-based interventions have been used to reach racial/ethnic minorities. In order to develop effective programs, we conducted a comprehensive systematic review of faith-based cancer prevention studies (2005~2016) to examine characteristics and promising strategies. Combination terms "church or faith-based or religion," "intervention or program," and "cancer education or lifestyle" were used in searching the five major databases: CINAHL; ERIC; Health Technology Assessments; MEDLINE; and PsycInfo. A total of 20 studies met study criteria. CDC's Community Guide was used to analyze and review group interventions. Analyses were organized by two racial groups: African American (AA) and Latino/Hispanic American groups. Results showed most studies reviewed focused on breast cancer alone or in combination with other cancers. Studies of Latino/Hispanic groups targeted more on uninsured, Medicare, or Medicaid individuals, whereas AA studies generally did not include specific insurance criteria. The sample sizes of the AA studies were generally larger. The majority of these studies reviewed used pre-post, posttest only with control group, or quasi-experience designs. The Health Belief Model was the most commonly used theory in both groups. Community-based participatory research and empowerment/ecological frameworks were also used frequently in the Latino/Hispanic studies. Small media and group education were the top two most popular intervention strategies in both groups. Although one-on-one strategy was used in some Latino studies, neither group used reducing client out-of-pocket costs strategy. Client reminders could also be used more in both groups as well. Current review showed church-based cancer education programs were effective in changing knowledge, but not always screening utilization. Results show faith-based cancer educational interventions are promising. To maximize intervention impact, future studies might consider using stronger study designs, incorporating a variety of proven effective strategies, including those frequently used evidence-based strategies, as well as exploring promising strategies among specific target groups.

Abstract
Policy Points: Policymakers in the United States should consider expanding pharmacy practice laws to allow pharmacists to vaccinate adolescents as a way to improve geographic access to adolescent vaccines, particularly for human papillomavirus (HPV) vaccine, which has low uptake. Our state-level analysis showed that pharmacists are more geographically dispersed than primary care physicians in the US state of Texas. Including pharmacists among available adolescent vaccine providers would improve the geographic distribution of vaccine providers, especially in areas with an inadequate number of primary care physicians. CONTEXT The largest disparities in human papillomavirus (HPV) vaccination in the United States are due to geography. One potential way of addressing these disparities is by improving geographic access to HPV vaccination. Two federal panels have recommended including community pharmacists as HPV vaccine providers as a strategy to improve opportunities for HPV vaccination for adolescents. We sought to evaluate whether community pharmacists can improve the number of vaccine providers in areas with primary care physician shortages in the US state of Texas. METHODS We gathered publicly available physician and pharmacist 2016 workforce data from the Texas Medical Board and Board of Pharmacy. We conducted geospatial analysis of census tracts to analyze the distribution of physicians and pharmacists and how pharmacists change vaccine provider coverage across the state. FINDINGS Census tracts with high numbers of physicians per capita tended to be located near one another, in 5 of 5 analyses of Moran's I (median = .04). In contrast, pharmacist rates were not spatially dependent on census tract in any of our analyses. If pharmacists were added to primary care physicians as vaccine providers, 35% of urban census tracts that previously had inadequate coverage would be adequately covered, while 18% of inadequately covered rural census tracts would become adequately covered. Overall, when pharmacists were included with primary care physicians as vaccine providers, vaccine providers per capita increased in 2,413 of the 4,508 urban census tracts (54%), while the rate increased in 223 of 746 rural census tracts (30%). CONCLUSIONS Pharmacists are more geographically dispersed across census tracts than primary care physicians. As a result, adding pharmacists to the workforce would increase the availability of vaccine providers in areas with inadequate primary care provider coverage.

Abstract
PURPOSE This study sought to evaluate the safety of conservative treatment in the management of patients with microinvasive cervical adenocarcinoma. METHODS The PubMed, PMC, EMBASE, Web of Science and Cochrane databases were searched to collect correlational studies published in English between January 1949 and May 2018. Series reports that evaluating the oncological prognoses of patients with microinvasive cervical adenocarcinoma who were treated with fertility-sparing surgery versus hysterectomy were pooled for meta-analysis and trial sequential analysis. RESULTS A total of 8 articles with 1256 patients were collected, including 7 retrospective reviews and 1 prospective study. Only one (0.08%) patient had parametrial involvement. Positive margins of surgical specimens were identified in 6 patients (2.2%). Lymph node metastasis was found in 5 patients (0.4%). The progression-free survival and overall survival rates were 99.3 and 98.2%. Fertility-sparing surgery had no adverse impact on recurrence or survival (P = 0.524 and 0.485, respectively). Regarding potential selection bias, significantly more patients with stage IA2 tumors than those with stage IA1 disease were treated with hysterectomy (P < 0.001). The trial sequential analysis indicated that the cumulative number of patients failed to meet the required sample size (number of patients). CONCLUSIONS The prognosis for patients with microinvasive cervical adenocarcinoma is excellent. Fertility preservation is at least appropriate for young women with stage IA1 adenocarcinoma. Further studies are still warranted to evaluate the safety of this procedure in managing patients with microinvasive cervical adenocarcinoma.

Abstract
PURPOSE Multiple intrapersonal and structural barriers, including geography, may prevent women from engaging in cervical cancer preventive care such as screening, diagnostic colposcopy, and excisional precancer treatment procedures. Geographic accessibility, stratified by rural and nonrural areas, to necessary services across the cervical cancer continuum of preventive care is largely unknown. METHODS Health care facility data for New Mexico (2010-2012) was provided by the New Mexico Human Papillomavirus Pap Registry (NMHPVPR), the first population-based statewide cervical cancer screening registry in the United States. Travel distance and time between the population-weighted census tract centroid to the nearest facility providing screening, diagnostic, and excisional treatment services were examined using proximity analysis by rural and nonrural census tracts. Mann-Whitney test (P < .05) was used to determine if differences were significant and Cohen's r to measure effect. FINDINGS Across all cervical cancer preventive health care services and years, women who resided in rural areas had a significantly greater geographic accessibility burden when compared to nonrural areas (4.4 km vs 2.5 km and 4.9 minutes vs 3.0 minutes for screening; 9.9 km vs 4.2 km and 10.4 minutes vs 4.9 minutes for colposcopy; and 14.8 km vs 6.6 km and 14.4 minutes vs 7.4 minutes for precancer treatment services, all P < .001). CONCLUSION Improvements in cervical cancer prevention should address the potential benefits of providing the full spectrum of screening, diagnostic and precancer treatment services within individual facilities. Accessibility, assessments distinguishing rural and nonrural areas are essential when monitoring and recommending changes to service infrastructures (eg, mobile versus brick and mortar).

Abstract
Background: Cancer incidence and mortality rates in the United States are declining, but this decrease may not be observed in rural areas where residents are more likely to live in poverty, smoke, and forego cancer screening. However, there is limited research exploring national rural-urban differences in cancer incidence and trends.Methods: We analyzed data from the North American Association of Central Cancer Registries' public use dataset, which includes population-based cancer incidence data from 46 states. We calculated age-adjusted incidence rates, rate ratios, and annual percentage change (APC) for: all cancers combined, selected individual cancers, and cancers associated with tobacco use and human papillomavirus (HPV). Rural-urban comparisons were made by demographic, geographic, and socioeconomic characteristics for 2009 to 2013. Trends were analyzed for 1995 to 2013.Results: Combined cancers incidence rates were generally higher in urban populations, except for the South, although the urban decline in incidence rate was greater than in rural populations (10.2% vs. 4.8%, respectively). Rural cancer disparities included higher rates of tobacco-associated, HPV-associated, lung and bronchus, cervical, and colorectal cancers across most population groups. Furthermore, HPV-associated cancer incidence rates increased in rural areas (APC = 0.724, P < 0.05), while temporal trends remained stable in urban areas.Conclusions: Cancer rates associated with modifiable risks-tobacco, HPV, and some preventive screening modalities (e.g., colorectal and cervical cancers)-were higher in rural compared with urban populations.Impact: Population-based, clinical, and/or policy strategies and interventions that address these modifiable risk factors could help reduce cancer disparities experienced in rural populations.

Abstract
BACKGROUND Uptake of the human papillomavirus (HPV) vaccine is low in Appalachian Ohio and areas with high cervical cancer rates. METHODS We conducted a group-randomized trial among 12 counties in Appalachian Ohio randomized to receive either an HPV vaccine (intervention counties) or influenza vaccine (comparison counties) multilevel intervention (MLI). Parents (n = 337) who had a daughter aged 9 to 17 years who had not received the HPV vaccine were recruited from commercial lists. Clinics (N = 24) and 119 providers from these clinics were also recruited. The primary outcome was medical record-confirmed receipt of the first shot of the HPV vaccine 3 months after receiving the intervention among daughters of parents enrolled in the study. Secondary outcomes included receipt of the first HPV vaccine shot by 6 months and changes in provider knowledge. RESULTS According to medical records, 10 (7.7%) daughters of intervention participants received the first shot of the HPV vaccine within 3 months of being sent the intervention materials compared with 4 (3.2%) daughters of comparison group participants (P = 0.061). By 6 months, 17 (13.1%) daughters of intervention participants received the first HPV vaccine shot compared with eight (6.5%) daughters of comparison group participants (P = 0.002). Provider knowledge about HPV increased (P < 0.001, from baseline to after education). CONCLUSIONS The MLI increased uptake of the HPV vaccine among girls aged 9 to 17 years; however, uptake was low. IMPACT To improve HPV vaccine uptake, attention to additional levels of influence (e.g., policy, community) and more elements within levels (e.g., reminders, automated prompts) may be needed.

Abstract
Here we evaluate the acceptability and feasibility of self-sample human papillomavirus (HPV) testing (self-HPV) among a sample of predominantly Mexican immigrant women who never or sporadically attend for Pap testing. Immigrant women who had not had a Pap test in the past 3 years (n = 100) were recruited. Participants self-collected a cervical sample for HPV testing. High-risk (HR) HPV-positive women were referred for clinical follow-up. Acceptability of self-HPV was high, with 99% reporting that they would be willing to use self-HPV regularly. Nineteen women (19%) tested positive for HR-HPV. Of these, 50% obtained clinical follow-up within 3 months. For those who did not, the primary barrier to follow-up was difficulty obtaining healthcare coverage. In conclusion, self-HPV is highly acceptable to Mexican immigrant women who otherwise do not attend for Pap testing. While the approach addresses critical barriers to primary screening, questions remain as to whether uninsured HR-HPV positive women are able to attend for clinical follow-up.

Abstract
PURPOSE To determine if differences in screening and vaccination patterns across the population may accentuate ethnic and geographic variation in future burden of disease. METHODS Using Cancer in North America data provided by the North American Association of Central Cancer Registries, county cervical cancer incidence trends from 1995 to 2009 were modeled for the entire United States using ecologic covariates. Rates for health service areas were also modeled by ethnicity. State-level incidence was mapped together with Papanicolaou (Pap) screening, past 3 years (women ≥ 18 years old), and three-dose human papillomavirus (HPV) vaccine coverage (girls 13 to 17 years old) to identify potential priority areas for preventive services. RESULTS US cervical cancer incidence decreased more during the periods 1995 to 1999 and 2000 to 2004 than during the period 2005 to 2009. During these 15 years, the most affected areas became increasingly confined to Appalachia, the lower Mississippi Valley, the Deep South, Texas, and Florida. Hispanic and black women experienced a higher incidence of cervical cancer than both white and Asian and Pacific Islander women during each period. Women in 10 of 17 states/districts with a high incidence (≥ 8.14/100,000) reported low Pap testing (< 78.5%), HPV vaccine coverage (< 33.9%), or both prevention technologies. CONCLUSION The decline in cervical cancer incidence has slowed in recent years. Access to HPV vaccination, targeted screening, and treatment in affected populations is needed to reduce cervical cancer disparities in the future.

Abstract
In this article, the American Cancer Society provides the estimated number of new cancer cases and deaths for blacks in the United States and the most recent data on cancer incidence, mortality, survival, screening, and risk factors for cancer. Incidence data are from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries, and mortality data are from the National Center for Health Statistics. Approximately 189,910 new cases of cancer and 69,410 cancer deaths will occur among blacks in 2016. Although blacks continue to have higher cancer death rates than whites, the disparity has narrowed for all cancers combined in men and women and for lung and prostate cancers in men. In contrast, the racial gap in death rates has widened for breast cancer in women and remained level for colorectal cancer in men. The reduction in overall cancer death rates since the early 1990s translates to the avoidance of more than 300,000 deaths among blacks. In men, incidence rates from 2003 to 2012 decreased for all cancers combined (by 2.0% per year) as well as for the top 3 cancer sites (prostate, lung, and colorectal). In women, overall rates during the corresponding time period remained unchanged, reflecting increasing trends in breast cancer combined with decreasing trends in lung and colorectal cancer rates. Five-year relative survival is lower for blacks than whites for most cancers at each stage of diagnosis. The extent to which these disparities reflect unequal access to health care versus other factors remains an active area of research. Progress in reducing cancer death rates could be accelerated by ensuring equitable access to prevention, early detection, and high-quality treatment.

Abstract
Many universities seek to improve the health and wellbeing of their faculty and staff through employer wellness programs but racial/ethnic disparities in health care use may still persist. The purpose of this research was to identify racial/ethnic disparities in the use of preventive health services at a Midwestern university. A record review was conducted of self-reported health data from University employees, examining the use of primary care and common screening procedures collected in a Personal Health Assessment conducted by the University's wellness program. Results show that there were significant racial/ethnic differences in the use of primary care and participation in screening. Notably, Asian employees in this sample were less likely to have a primary care provider and participate in routine cancer screenings. The observed racial/ethnic differences in screening behavior were mediated by the use of primary care. Together, these data show that despite equal access to care, racial and ethnic disparities in screening persist and that having a primary care provider is an important predictor of screening behavior. Results suggest that health communications designed to increase screening among specific racial/ethnic minority groups should target primary care use.

Abstract
BACKGROUND Healthcare providers may vary their communications with different patients, which could give rise to differences in vaccination coverage. We examined demographic disparities in parental report of collaborative provider communication and implications for human papillomavirus (HPV) vaccination. METHODS Participants were 4,124 parents who completed the National Immunization Survey-Teen about daughters ages 13-17. We analyzed disparities in collaborative communication (mutual information exchange, deliberation, and decision) and whether they mediated the relationship between demographic characteristics and HPV vaccine initiation. RESULTS Half of parents (53%) in the survey reported collaborative communication. Poor, less educated, Spanish-speaking, Southern, and rural parents, and parents of non-privately insured and Hispanic adolescents, were least likely to report collaborative communication (all p<.05). These disparities in communication accounted for geographic variation in HPV vaccination, specifically, the higher rates of uptake in the Northeast versus the South (mediation z=2.31, p<.01) and in urban/suburban vs. rural areas (mediation z=2.87, p<.01). These disparities were also associated with vaccination among subgroups with relatively high coverage, minimizing what could have been even higher uptake among Hispanic compared to non-Hispanic white adolescents (mediation z=-3.04, p<.01) and non-privately versus privately insured adolescents (mediation z=-3.67, p<.001). Controlling for provider recommendation attenuated some of these associations (but all p<.10). CONCLUSIONS Collaborative communication showed widespread disparities, being least common among underserved groups. Collaborative communication helped account for differences-and lack of differences-in HPV vaccination among some subgroups of adolescent girls. Leveraging patient-provider communication, especially for underserved demographic groups, could improve HPV vaccination coverage.

Abstract
Cervical cancer is the second most common cause of cancer-related death among women worldwide, with over 500,000 new cases diagnosed annually and 50% mortality rate in Asia. In the United States, approximately 10,370 new cases of cervical cancer are diagnosed annually, and estimated 3,710 deaths occur from the disease, making it the sixth most common cause of malignancy among American women. This study aims to provide awareness about cervical cancer as well as an updated knowledge about the prevalence and incidence of cervical cancer in Asia.

Abstract
BACKGROUND Limited literature is available about cancer in the Appalachian Region. This is the only known analysis of all cancers for Appalachia and non-Appalachia covering 100% of the US population. Appalachian cancer incidence and trends were evaluated by state, sex, and race and compared with those found in non-Appalachian regions. METHODS US counties were identified as Appalachian or non-Appalachian. Age-adjusted cancer incidence rates, standard errors, and confidence intervals were calculated using the most recent data from the United States Cancer Statistics for 2004 to 2011. RESULTS Generally, Appalachia carries a higher cancer burden compared with non-Appalachia, particularly for tobacco-related cancers. For all cancer sites combined, Appalachia has higher rates regardless of sex, race, or region. The Appalachia and non-Appalachia cancer incidence gap has narrowed, with the exception of oral cavity and pharynx, larynx, lung and bronchus, and thyroid cancers. CONCLUSIONS Higher cancer incidence continues in Appalachia and appears at least in part to reflect high tobacco use and potential differences in socioeconomic status, other risk factors, patient health care utilization, or provider practices. It is important to continue to evaluate this population to monitor results from screening and early detection programs, understand behavioral risk factors related to cancer incidence, increase efforts to reduce tobacco use and increase cancer screening, and identify other areas where effective interventions may mediate disparities. IMPACT Surveillance and evaluation of special populations provide means to monitor screening and early detection programs, understand behavioral risk factors, and increase efforts to reduce tobacco use to mediate disparities.

Abstract
Human papillomavirus (HPV) 16 and 18 causes 66% of cervical cancers (Dunne et al., 2014). Vaccination during adolescence can prevent HPV-associated cervical cancers, yet less than half of adolescent girls are vaccinated. This study examined the association between HPV knowledge and parental intentions to vaccinate daughters against HPV. A retrospective, cross-sectional, national data set from the 2006-2007 Health Information National Trends Survey (HINTS) was used. A multivariate multinomial logistic regression analysis was used to estimate the association between intent to vaccinate and HPV knowledge. After controlling for other covariates, parents who were knowledgeable were more likely to intend to have their daughters vaccinated compared with those who were not knowledgeable (adjusted relative risk ratio [aRRR] = 3.96, p = .004). Having HPV knowledge would significantly increase parents' intent for vaccination against the disease for their daughters. Health care providers should integrate HPV-related education for parents within their services, and policymakers should consider requiring HPV vaccination for school attendance.

Abstract
Cancer is the leading cause of death among Hispanics/Latinos, who represent the largest racial/ethnic minority group in the United States, accounting for 17.4% (55.4 million/318 million) of the total US population in 2014. Every 3 years, the American Cancer Society reports on cancer statistics for Hispanics based on incidence data from the National Cancer Institute, the Centers for Disease Control and Prevention, and the North American Association of Central Cancer Registries and mortality data from the National Center for Health Statistics. Among Hispanics in 2015, there will be an estimated 125,900 new cancer cases diagnosed and 37,800 cancer deaths. For all cancers combined, Hispanics have 20% lower incidence rates and 30% lower death rates compared with non-Hispanic whites (NHWs); however, death rates are slightly higher among Hispanics during adolescence (aged 15-19 years). Hispanic cancer rates vary by country of origin and are generally lowest in Mexicans, with the exception of infection-associated cancers. Liver cancer incidence rates in Hispanic men, which are twice those in NHW men, doubled from 1992 to 2012; however, rates in men aged younger than 50 years declined by 43% since 2003, perhaps a bellwether of future trends for this highly fatal cancer. Variations in cancer risk between Hispanics and NHWs, as well as between subpopulations, are driven by differences in exposure to cancer-causing infectious agents, rates of screening, and lifestyle patterns. Strategies for reducing cancer risk in Hispanic populations include increasing the uptake of preventive services (e.g., screening and vaccination) and targeted interventions to reduce obesity, tobacco use, and alcohol consumption.

Abstract
Human papillomavirus (HPV) vaccine uptake among 18-26 y old women varies by geographic region in the US. However, little is known about regional variations in vaccination among girls who are in the vaccine's targeted age groups. Regional variation in HPV vaccination among female adolescents (9-17 y old) was examined using cross-sectional data from the Behavioral Risk Factor Surveillance System (BRFSS) between 2008 and 2010. Multivariable logistic regression estimated the association of region of residence (10 states included questions about adolescent HPV vaccination) with uptake and completion of the 3-shot HPV vaccine series. Among 7,849 adolescents, 26.9% initiated, and 55.2% of initiators completed the series. Adolescents from Northeast/Midwest/West states were 1.74 (95% CI: 1.45-2.10) times more likely to have initiated HPV vaccination compared to the South/Southwestern states. Among initiators, vaccine series completion did not vary significantly between the South/Southwestern and Northeast/Midwest/West states. Flu vaccination was associated with increased odds of initiation in both regions and completion of the HPV vaccine series in the South/Southwestern states only. Girls 9-10 and 11-12 y old were less likely to have initiated and 11-12 y olds were less likely to have completed the HPV vaccine series compared to 13-17 y olds. The observed regional variations in vaccination could cause rates of cervical cancer to remain higher in the South/Southwest and widen currently observed regional disparities in cervical cancer rates.

Abstract
BACKGROUND There is a lack of information about the correlates of completing all three cancer screening tests among women living in Appalachia. METHODS Cross-sectional telephone interviews were conducted (April-September 2013) among women (n = 637) ages 51 to 75 years from 12 Appalachia Ohio counties. Outcomes of within screening guidelines were verified by medical records. Multivariable logistic regression models identified correlates of being within guidelines for all three cancer screening tests. RESULTS Screening rates included mammography (32.1%), Pap test (36.1%), and a colorectal cancer test (30.1%). Only 8.6% of women were within guidelines for all tests. Having had a check-up in the past 2 years and having received a screening recommendation were significantly related to being within guidelines for all three tests (P < 0.01). Participants with higher annual household incomes [$60,000+; OR, 3.53; 95% confidence interval (CI), 1.49-8.33] and conditions requiring regular medical visits (OR, 3.16; 95% CI, 1.29-7.74) were more likely to be within guidelines for all three screening tests. CONCLUSION Less than 10% of women had completed screening within guidelines for all three screening tests. Regular contact with the health care system and higher incomes were significant predictors of being within guidelines. IMPACT Within guidelines rates for the three recommended cancer screening tests are low among women in Appalachia Ohio. This finding illustrates the need for innovative interventions to improve rates of multiple cancer screening tests.

Abstract
Background Intrahepatic (ICC) and extrahepatic cholangiocarcinomas (ECC) are tumors that arise from cholangiocytes in the bile duct, but ICCs are coded as primary liver cancers while ECCs are coded as biliary tract cancers. The etiology of these tumors is not well understood. It has been suggested that the etiology of ICC is more similar to that of another type of liver cancer, hepatocellular carcinoma (HCC), than to the etiology of ECC. If this is true, geographic incidence patterns and trends in ICC incidence should be more similar to that of HCC than ECC. Methods To examine this hypothesis, data from the North American Association of Central Cancer Registries Cancer in North America data file were analyzed. Incidence rates and joinpoint trends were calculated by demographic subgroup. County-level incidence rates were mapped. Results Overall incidence rates, racial distribution, male:female ratio, and peak ages were more similar between ICC and ECC than with HCC. During 2000–2009, average annual incidence rates of ECC increased. During 2005–2009, average annual ICC incidence rates also increased. High rates for all three cancer sites were found in the Pacific region, particularly Hawaii and Alaska. Rates of ICC and ECC were also high in the Northeast and the upper Midwest, while rates of HCC were high in the South. Conclusions Demographic patterns and geographical variation were more closely related between ICC and ECC than HCC, suggesting that the etiology of ICC and ECC may be similar. Increasing rates of both tumors suggest that further etiology studies are warranted.

Abstract
OBJECTIVES We examined stage of diagnosis and survival after cervical cancer among Hispanic women, and their associations with Hispanic nativity, and explored whether neighborhood socioeconomic status (SES) and residence in a Hispanic enclave modify the association of nativity with stage and survival. METHODS We used California Cancer Registry data (1994-2009) to identify 7958 Hispanic women aged 21 years and older with invasive cervical cancer. We used logistic and Cox proportional hazards models to estimate the associations between stage and mortality with nativity, neighborhood factors, and other covariates. RESULTS Foreign-born women had similar adjusted relative odds of being diagnosed with stages II through IV (vs stage I) cervical cancer compared with US-born Hispanic women. However, among foreign-born women, those in low-SES-low-enclave neighborhoods were more likely to have late-stage disease than those in high-SES-low-enclave neighborhoods (adjusted odds ratio=1.91; 95% confidence interval=1.18, 3.07). Foreign-born women had lower cervical cancer mortality (adjusted hazard ratio=0.67; 95% confidence interval=0.58, 0.76) than US-born women, but only in high enclaves. CONCLUSIONS Among Hispanic women, nativity, neighborhood enclaves, and SES interact in their influence on stage and survival of cervical cancer.

Abstract
BACKGROUND From 1969 to 1998, keratinocyte carcinoma (KC) mortality rates declined as reported on death certificates, despite increasing incidence of KC. OBJECTIVE To estimate KC mortality trends from 1999 to 2010 in the United States. METHODS Descriptive and linear regression analysis using population-based death certificate data from the US National Center for Health Statistics. RESULTS On average, 1,491 deaths from nongenital KC and 1,058 deaths from genital KC were reported annually. Keratinocyte carcinoma mortality rates were stable or increasing over the study period. Highest nongenital mortality rates were seen in those older than 85 years (p < .001), men (p < .001), whites (p < .001), the South for white males (p = .001) and white females (p = .018), and nonmetropolitan areas for white males (p <.001), white females (p < .001), and black females (p = .005). Correlation between state UV Index and KC mortality existed for men (p = .004) but not for women (p = .379). Genital KC deaths increased with age (p < .001), in women (p < .001), and in less urbanized areas for white males (p < .001). CONCLUSION Keratinocyte carcinoma poses a serious health burden, which may be underestimated by death certificate reporting. Mortality rates are no longer declining. Increasing awareness of genital and nongenital KC, especially the elderly, and population-based studies with controlled reporting of KC mortality are needed.

Abstract
BACKGROUND Cervical cancer screening is one of the greatest cancer prevention achievements, yet some women still develop or die from this disease. OBJECTIVE To assess recent trends in cervical cancer incidence and mortality, current screening percentages, and factors associated with higher incidence and death rates and inadequate screening. METHODS Percentages of women who had not been screened for cervical cancer in the past 5 years were estimated using data from the 2012 Behavioral Risk Factor Surveillance System survey. State-specific cervical cancer incidence data from the United States Cancer Statistics and mortality data from the National Vital Statistics System were used to calculate incidence and death rates for 2011 by state. Incidence and death rates and annual percentage changes from 2007 to 2011 were calculated by state and U.S. Census region. RESULTS In 2012, the percentage of women who had not been screened for cervical cancer in the past 5 years was estimated to be 11.4%; the percentage was larger for women without health insurance (23.1%) and for those without a regular health care provider (25.5%). From 2007 to 2011, the cervical cancer incidence rate decreased by 1.9% per year while the death rate remained stable. The South had the highest incidence rate (8.5 per 100,000), death rate (2.7 per 100,000), and percentage of women who had not been screened in the past 5 years (12.3%). CONCLUSIONS Trends in cervical cancer incidence rates have decreased slightly while death rates have been stable over the last 5 years. The proportion of inadequately screened women is higher among older women, Asians/Pacific Islanders, and American Indians/Alaska Natives. IMPLICATIONS FOR PUBLIC HEALTH PRACTICE There continue to be women who are not screened as recommended, and women who die from this preventable cancer. Evidence-based public health approaches are available to increase women's access to screening and timely follow-up of abnormal results.

Abstract
OBJECTIVE This study aimed to evaluate the screening histories and compare barriers to screening between women with newly diagnosed early-stage cervical cancer versus advanced stage cervical cancer. MATERIALS AND METHODS Between August 2010 and August 2011, women with invasive cervical cancer were identified at a single urban academic referral center and surveyed regarding access to health care, screening history, and barriers to screening services. The following 2 groups were identified: women with early-stage disease (ESD) (stages 1A1-1B2) and women with advanced-stage disease (ASD) (stages IIA-IV). RESULTS A total of 65 women were enrolled. Thirty-eight women (58%) had ESD, and 27 (42%) had ASD. Patients with ESD had an average time since last Pap smear of 5.4 years compared with 10.7 years in patients with ASD (p = .014). Ten patients (26%) with ESD had screening histories compliant with recommendations compared with 0 patients (0%) with ASD (p = .004). Seventeen (45%) of 38 patients with ESD and 8 (30%) of 27 patients with ASD reported no barriers to accessing screening (p = nonsignificant [NS]). Financial difficulties were the most common barrier in 12 women with ESD (32%) and 7 women with ASD (41%) (p = NS). High levels of family support were noted in both groups (74% and 70%, p = NS). CONCLUSIONS Time since last Pap smear varied significantly in women with early versus advanced cervical cancer. Women with compliant screening histories still developed invasive cervical cancer, but none presented at an advanced stage. There were no significant differences in specific barriers to accessing health care and screening services between women with ESD compared with ASD. More than one third of patients reported no barriers to care, suggesting a need for improved awareness of screening recommendations.

Abstract
Epidemiologists are gradually incorporating spatial analysis into health-related research as geocoded cases of disease become widely available and health-focused geospatial computer applications are developed. One health-focused application of spatial analysis is cluster detection. Using cluster detection to identify geographic areas with high-risk populations and then screening those populations for disease can improve cancer control. SaTScan is a free cluster-detection software application used by epidemiologists around the world to describe spatial clusters of infectious and chronic disease, as well as disease vectors and risk factors. The objectives of this article are to describe how spatial analysis can be used in cancer control to detect geographic areas in need of colorectal cancer screening intervention, identify issues commonly encountered by SaTScan users, detail how to select the appropriate methods for using SaTScan, and explain how method selection can affect results. As an example, we used various methods to detect areas in Florida where the population is at high risk for late-stage diagnosis of colorectal cancer. We found that much of our analysis was underpowered and that no single method detected all clusters of statistical or public health significance. However, all methods detected 1 area as high risk; this area is potentially a priority area for a screening intervention. Cluster detection can be incorporated into routine public health operations, but the challenge is to identify areas in which the burden of disease can be alleviated through public health intervention. Reliance on SaTScan’s default settings does not always produce pertinent results.

Abstract
BACKGROUND Improved parental awareness of human papillomavirus (HPV) vaccines could increase uptake of vaccines early in the life course, thereby reducing adolescents' later risk for HPV infection and cancer. As such, we sought to determine factors related to parental awareness of HPV vaccines, using a nationally representative population-based sample. METHODS We examined data on 5735 parents of preadolescents and adolescents aged 8 to 17 years from the 2010 National Health Interview Survey. Parents were asked if they had ever heard of HPV vaccines or shots. Multivariable logistic regression analyses were used to examine the odds of parental awareness of HPV vaccines, controlling for relevant covariates. RESULTS Most US parents (62.6%) heard of HPV vaccines. Multivariable results revealed parents of children who were older, female, and insured were more likely to have heard of HPV vaccines; parents who were female, white (non-Hispanic), English speakers, born in the United States, married or living with a partner, more educated, and had higher income were also more likely to be aware of HPV vaccines. Notably, parents of children who had a well-child checkup in the last 12 months were significantly more likely to have heard of HPV vaccines (odds ratio, 1.23; 95% confidence interval, 1.04-1.46). CONCLUSIONS Given the significant disparities in parental awareness of HPV vaccines, improving access to preventive pediatric health care could offer an opportunity to increase parental awareness. In addition, public health efforts that provide culturally sensitive information in a variety of languages may be an effective way to reach vulnerable groups.

Abstract
OBJECTIVES To review the extent of health disparities in gynecologic cancer care and outcomes and to propose recommendations to help counteract the disparities. METHODS We searched the electronic databases PubMed and the Cochrane Library. We included studies demonstrating quantifiable differences by race and ethnicity in the incidence, treatment, and survival of gynecologic cancers in the United States (US). Most studies relied on retrospective data. We focused on differences between Black and White women, because of the limited number of studies on non-Black women. RESULTS White women have a higher incidence of ovarian cancer compared to Black women. However, the all-cause ovarian cancer mortality in Black women is 1.3 times higher than that of White women. Endometrial and cervical cancer mortality in Black women is twice that of White women. The etiology of these disparities is multifaceted. However, much of the evidence suggests that equal care leads to equal outcomes for Black women diagnosed with gynecologic cancers. Underlying molecular factors may play an additional role in aggressive tumor biology and endometrial cancer disparities. CONCLUSION Gynecologic cancer disparities exist between Black and White women. The literature is limited by the lack of large prospective trials and adequate numbers of non-Black racial and ethnic groups. We conclude with recommendations for continued research and a multifaceted approach to eliminate gynecologic cancer disparities.

Abstract
OBJECTIVE The Carolina Framework for Cervical Cancer Prevention describes 4 main causes of cervical cancer incidence: human papillomavirus (HPV) infection, lack of screening, screening errors, and not receiving follow-up care. We present 2 applications of the Carolina Framework in which we identify high-need counties in North Carolina and generate recommendations for improving prevention efforts. METHODS We created a cervical cancer prevention need index (CCPNI) that ranked counties on cervical cancer mortality, HPV vaccine initiation and completion, Pap smear screening, and provision of Pap tests to rarely- or never-screened women. In addition, we conducted in-depth interviews with 19 key informants from programs and agencies involved in cervical cancer prevention in North Carolina. RESULTS North Carolina's 100 counties varied widely on individual CCPNI components, including annual cervical cancer mortality (median 2.7/100,000 women; range 0.0-8.0), adolescent girls' HPV vaccine initiation (median 42%; range 15%-62%), and Pap testing in the previous 3 years among Medicaid-insured adult women (median 59%; range 40%-83%). Counties with the greatest prevention needs formed 2 distinct clusters in the northeast and south-central regions of the state. Interviews generated 9 recommendations to improve cervical cancer prevention in North Carolina, identifying applications to specific programs and policies in the state. CONCLUSIONS This study found striking geographic disparities in cervical cancer prevention need in North Carolina. Future prevention efforts in the state should prioritize high-need regions as well as recommended strategies and applications in existing programs. Other states can use the Carolina Framework to increase the impact of their cervical cancer prevention efforts.

Abstract
OBJECTIVE Declines in cervical cancer incidence and mortality in Canada and in the United States have been widely attributed to the introduction of the Papanicolaou (Pap) test. This article reviews changes in screening and introduction of HPV vaccination. METHOD Sentinel events in cervical cancer screening and primary prevention through HPV vaccination in the US and Canada are described. RESULTS Despite commonalities, cervical cancer screening and prevention differ between the two countries. Canada has a combination of opportunistic and organized programs at the provincial and territorial level, while the US has opportunistic screening and vaccination systems. In the US, the HPV test along with the Pap test (co-testing) is part of national recommendations for routine cervical cancer screening for women age 30 and older. Co-testing is not being considered anywhere in Canada, but primary HPV testing is currently recommended (but not implemented) in one province in Canada. CONCLUSION Many prevention strategies are available for cervical cancer. Continued public health efforts should focus on increasing vaccine coverage in the target age groups and cervical cancer screening for women at appropriate intervals. Ongoing evaluation will be needed to ensure appropriate use of health resources, as vaccinated women become eligible for screening.

Are HPV vaccination services accessible to high-risk communities? A spatial analysis of HPV-associated cancer and Chlamydia rates and safety-net clinics. Cancer Causes Control 2013; 24:2089-98.

Abstract
PURPOSE While HPV vaccines can greatly benefit adolescents and young women from high-risk areas, little is known about whether safety-net immunization services are geographically accessible to communities at greatest risk for HPV-associated diseases. We explore the spatial relationship between areas with high HPV risk and proximity to safety-net clinics from an ecologic perspective. METHODS We used cancer registry data and Chlamydia surveillance data to identify neighborhoods within Los Angeles County with high risk for HPV-associated cancers. We examined proximity to safety-net clinics among neighborhoods with the highest risk. Proximity was measured as the shortest distance between each neighborhood center and the nearest clinic and having a clinic within 3 miles of each neighborhood center. RESULTS The average 5-year non-age-adjusted rates were 1,940 cases per 100,000 for Chlamydia and 60 per 100,000 for HPV-associated cancers. A large majority, 349 of 386 neighborhoods with high HPV-associated cancer rates and 532 of 537 neighborhoods with high Chlamydia rates, had a clinic within 3 miles of the neighborhood center. Clinics were more likely to be located within close proximity to high-risk neighborhoods in the inner city. High-risk neighborhoods outside of this urban core area were less likely to be near accessible clinics. CONCLUSIONS The majority of high-risk neighborhoods were geographically near safety-net clinics with HPV vaccination services. Due to low rates of vaccination, these findings suggest that while services are geographically accessible, additional efforts are needed to improve uptake. Programs aimed to increase awareness about the vaccine and to link underserved groups to vaccination services are warranted.
