RESUMEN

Hysterectomy protects against cervical cancer when the cervix is removed. However, measures of cervical cancer incidence often fail to exclude women with a hysterectomy from the population-at-risk denominator, underestimating and distorting disease burden. In this study, we estimated hysterectomy prevalence from the Behavioral Risk Factor Surveillance System surveys to remove the women who were not at risk of cervical cancer from the denominator and combined these estimates with the US Cancer Statistics data. From these data, we calculated age-specific and age-standardized incidence rates for women aged >30 years from 2001-2019, adjusted for hysterectomy prevalence. We calculated the difference between unadjusted and adjusted incidence rates and examined trends by histology, age, race and ethnicity, and geographic region using joinpoint regression. The hysterectomy-adjusted cervical cancer incidence rate from 2001-2019 was 16.7 per 100 000 women-34.6% higher than the unadjusted rate. After adjustment, incidence rates were higher by approximately 55% among Black women, 56% among those living in the East South Central division, and 90% among women aged 70-79 and ≥80 years. These findings underscore the importance of adjusting for hysterectomy prevalence to avoid underestimating cervical cancer incidence rates and masking disparities by age, race, and geographic region. This article is part of a Special Collection on Gynecological Cancers.

RESUMEN

BACKGROUND: Little is known about cervical cancer screening strategy utilization (cytology alone, cytology plus high-risk human papillomavirus [HPV] testing [cotesting], primary HPV testing) and test results in the United States. METHODS: Data from the Centers for Disease Control and Prevention's National Breast and Cervical Cancer Early Detection Program were analyzed for 199,578 persons aged 21-65 years screened from 2019 to 2020. Screening test utilization and results were stratified by demographic characteristics and geographic region. Age-standardized pooled HPV test positivity and genotyping test positivity were estimated within cytology result categories. RESULTS: Primary HPV testing was performed in 592 persons (0.3%). Among the remaining 176,290 persons aged 30-65 years, cotesting was utilized in 72.1% (95% confidence interval [CI] 71.9-72.3%), and cytology alone was utilized in 27.9% (95% CI 27.7-28.1%). Utilization of cytology alone varied by geographic region, ranging from 18.3% (95% CI 17.4-19.1%) to 49.0% (95% CI 48.4-49.6%). HPV genotyping test utilization among those with positive pooled HPV test results was 33.9%. In persons aged ≥30 years, variations in age-adjusted test results by region were observed for pooled HPV-positive test results and for HPV genotyping-positive test results. CONCLUSIONS: Cervical cancer screening strategy utilization and test results vary substantially by geographic region within a national screening program. Variation in utilization may be due to regional differences in screening test availability or the preferences of healthcare systems, screened persons and/or clinicians. Test result variations may reflect differing risk factors for HPV infections by geographic region.

RESUMEN

PURPOSE: We report the prevalence and economic cost of skin cancer treatment compared to other cancers overall in the USA from 2012 to 2018. METHODS: Using the Medical Expenditure Panel Survey full-year consolidated data files and associated medical conditions and medical events files, we estimate the prevalence, total costs, and per-person costs of treatment for melanoma and non-melanoma skin cancer among adults aged ≥ 18 years in the USA. To understand the changes in treatment prevalence and treatment costs of skin cancer in the context of overall cancer treatment, we also estimate the prevalence, total costs, and per-person costs of treatment for non-skin cancer among US adults. RESULTS: During 2012-15 and 2016-18, the average annual number of adults treated for any skin cancer was 5.8 (95% CI: 5.2, 6.4) and 6.1 (95% CI: 5.6, 6.6) million, respectively, while the average annual number of adults treated for non-skin cancers rose from 10.8 (95% CI: 10.0, 11.5) to 11.9 (95% CI: 11.2, 12.6) million, respectively. The overall estimated annual costs rose from $8.0 (in 2012-2015) to $8.9 billion (in 2016-18) for skin cancer treatment and $70.2 to $79.4 billion respectively for non-skin cancer treatment. CONCLUSION: The prevalence and economic cost of skin cancer treatment modestly increased in recent years. Given the substantial cost of skin cancer treatment, continued public health attention to implementing evidence-based sun-safety interventions to reduce skin cancer risk may help prevent skin cancer and the associated treatment costs.

RESUMEN

PURPOSE: We estimated up-to-date state- and territory-level hysterectomy prevalence and trends, which can help correct the population at risk denominator and calculate more accurate uterine and cervical cancer rates. METHODS: We analyzed self-reported data for a population-based sample of 1,267,013 U.S. women aged ≥ 18 years who participated in the Behavioral Risk Factor Surveillance System surveys from 2012 to 2020. Estimates were age-standardized and stratified by sociodemographic characteristics and geography. Trends were assessed by testing for any differences in hysterectomy prevalence across years. RESULTS: Hysterectomy prevalence was highest among women aged 70-79 years (46.7%) and ≥ 80 years (48.8%). Prevalence was also higher among women who were non-Hispanic (NH) Black (21.3%), NH American Indian and Alaska Native (21.1%), and from the South (21.1%). Hysterectomy prevalence declined by 1.9 percentage points from 18.9% in 2012 to 17.0% in 2020. CONCLUSIONS: Approximately one in five U.S. women overall and half of U.S. women aged ≥ 70 years reported undergoing a hysterectomy. Our findings reveal large variations in hysterectomy prevalence within and between each of the four census regions and by race and other sociodemographic characteristics, underscoring the importance of adjusting epidemiologic measures of uterine and cervical cancers for hysterectomy status.

RESUMEN

PURPOSE: Previous reports of gynecologic cancer rates have adjusted for hysterectomy prevalence with data from the Behavioral Risk Factor Surveillance System (BRFSS) or the National Health Interview Survey (NHIS). We sought to determine if BRFSS and NHIS produce similar estimates of hysterectomy prevalence. METHODS: Using data from BRFSS and NHIS, we calculated hysterectomy prevalence for women aged 20-79 years, stratified by 10-year age groups, survey year (2010, 2018), and race/ethnicity (Hispanic, non-Hispanic American Indian or Alaskan Native, non-Hispanic Asian, non-Hispanic Black, non-Hispanic White, non-Hispanic all other race groups). RESULTS: BRFSS and NHIS produced similar increasing trends in hysterectomy prevalence by age and directional differences by race and ethnicity. Fewer than 2% of women aged 20-29 years and more than 4 out of 10 women aged 70-79 years reported having had a hysterectomy. CONCLUSION: Our analyses suggest adjustment for hysterectomy prevalence with data from either survey would likely reduce distortion in cervical and uterine cancer rates. BRFSS, a survey which has a larger sample size than NHIS, may better support analyses of hysterectomy estimates for smaller subpopulations.

RESUMEN

Vulvar cancer incidence has been rising in recent years, possibly due to increasing exposure to human papillomavirus (HPV). We assessed incidence rates of HPV-associated and non-HPV-associated vulvar cancers diagnosed from 2001 to 2017 in the United States (US). Using population-based cancer registry data covering 99% of the US population, incidence rates were calculated and stratified by age, race/ethnicity, stage, geographic region, and histology. The average annual percent change in incidence per year were calculated using joinpoint regression. From 2001 to 2017, the incidence of HPV-associated vulvar cancers increased by 1.2% per year, most notably among women who were aged 50-59 years (2.6%), 60-69 years (2.4%), and ≥ 70 years (0.9%); of White (1.5%) and Black (1.1%) race; diagnosed at an early (1.3%) and late (1.8%) stage; and living in the Midwest (1.9%), Northeast (1.4%), and South (1.2%). Incidence increased each year for HPV-associated histologic subtypes including keratinizing (4.7%), non-keratinizing (6.0%), and basaloid (3.1%) squamous cell carcinomas (SCCs), while decreases were found in warty (2.7%) and microinvasive (5.5%) SCCs. HPV-associated vulvar cancer incidence increased overall and among women aged over 50 years while remaining stable among women younger than 50 years. The overall incidence for non-HPV-associated cancers was stable. Continued surveillance of HPV-associated cancers will allow us to monitor future trends as HPV vaccination coverage increases in the US.

RESUMEN

Human papilloma virus (HPV) vaccination for adolescents aged 11-12 years and cervical cancer screening for women aged 21-65 years are recommended to help prevent cervical cancer. The purpose of this study was to describe 2018 National Committee for Quality Assurance (NCQA) Healthcare Effectiveness Data and Information Set (HEDIS®) data for the United States on HPV vaccination and cervical cancer screening from 275 commercial preferred provider organizations (PPOs), 219 commercial health maintenance organizations (HMOs), and 204 Medicaid HMOs. The Centers for Disease Control and Prevention and NCQA analyzed the data in 2021. The HEDIS® measure for HPV vaccination was the percentage of male and female adolescents aged 13 years who completed HPV immunization (2- or 3-dose series) on or before their 13th birthday. The measure for cervical cancer screening was the percentage of women screened either with cervical cytology within the last 3 years for women aged 21-64 years or with cervical cytology/HPV co-testing within the last 5 years for women aged 30-64 years. Nationally, the mean rate for HPV vaccination in 2018 was 37.8% in Medicaid HMOs, 30.3% in commercial HMOs, and 24.9% in commercial PPOs. The mean rate for cervical cancer screening was 75.9% in commercial HMOs, 72.6% in commercial PPOs, and 60.3% among Medicaid HMOs. Medicaid HMOs reported higher HPV vaccination rates but lower cervical cancer screening rates than commercial plans. These differences raise questions about explanatory factors and how to improve prevention performance by plan category.

RESUMEN

OBJECTIVES: In the 2019 ASCCP Risk-Based Management Consensus Guidelines, clinical management decisions are based on immediate and 5-year cervical intraepithelial neoplasia (CIN) 3+ risk estimates. However, data for technologies other than human papillomavirus testing and cytology may be limited to clinical trials and observational studies of shorter duration than 5 years. To enable decisions about 1- or 3-year intervals, 3-year CIN 3+ risk equivalents to 5-year CIN 3+ risk thresholds were generated. MATERIALS AND METHODS: We examined screening test result scenarios around the 5-year risk thresholds of 0.15% and 0.55% and calculated the average percent increase in CIN 3+ risk from 3 to 5 years. Using this average increase, we obtained estimates of corresponding risk thresholds at 3 years. We then validated whether use of the 3-year risk threshold would have resulted in equivalent management per the 2019 recommendations. RESULTS: Around the 5-year CIN 3+ risk threshold of 0.55%, the average increase in risk from 3 to 5 years was 0.16%. Therefore, the equivalent threshold for 3-year risk was estimated as 0.39%. We found no difference in recommendations to return in 1 or 3 years using the 3-year or 5-year risk thresholds in 66 of the 67 scenarios (98.5%) in follow-up in 2019 guidelines. CONCLUSIONS: In this methodological addendum, the Enduring Guidelines Committee adopted the use of the 0.39% 3-year CIN 3+ risk threshold as equivalent of the 0.55% 5-year CIN 3+ risk threshold for technologies with fewer than 5 years of follow-up data. This allows evidence-based guidance for surveillance intervals of 1 or 3 years for new technologies with limited longitudinal data.

RESUMEN

BACKGROUND: US population-based cancer registries can be used for surveillance of human papillomavirus (HPV) types found in HPV-associated cancers. Using this framework, HPV prevalence among high-grade cervical precancers and invasive cervical cancers were compared before and after HPV vaccine availability. METHODS: Archived tissue from 2 studies of cervical precancers and invasive cervical cancers diagnosed from 1993-2005 (prevaccine) were identified from 7 central cancer registries in Florida; Hawaii; Iowa; Kentucky; Louisiana; Los Angeles County, California; and Michigan; from 2014 through 2015 (postvaccine) cases were identified from 3 registries in Iowa, Kentucky, and Louisiana. HPV testing was performed using L1 consensus polymerase chain reaction analysis. HPV-type-specific prevalence was examined grouped by hierarchical attribution to vaccine types: HPV 16, 18, HPV 31, 33, 45, 52, 58, other oncogenic HPV types, and other types/HPV negative. Generalized logit models were used to compare HPV prevalence in the prevaccine study to the postvaccine study by patient age, adjusting for sampling factors. RESULTS: A total of 676 precancers (328 prevaccine and 348 postvaccine) and 1140 invasive cervical cancers (777 prevaccine and 363 postvaccine) were typed. No differences were observed in HPV-type prevalence by patient age between the 2 studies among precancers or invasive cancers. CONCLUSIONS: The lack of reduction in vaccine-type prevalence between the 2 studies is likely explained by the low number of cases and low HPV vaccination coverage among women in the postvaccine study. Monitoring HPV-type prevalence through population-based strategies will continue to be important in evaluating the impact of the HPV vaccine.

RESUMEN

OBJECTIVE: To examine trends in the use of cervical cancer screening tests during 2013-2019 among commercially insured women. METHODS: The study population included women of all ages with continuous enrollment each year in the IBM MarketScan commercial or Medicare supplemental databases and without known history of cervical cancer or precancer (range = 6.9-9.8 million women per year). Annual cervical cancer screening test use was examined by three modalities: cytology alone, cytology plus HPV testing (cotesting), and HPV testing alone. Trends were assessed using 2-sided Poisson regression. RESULTS: Use of cytology alone decreased from 34.2% in 2013 to 26.4% in 2019 among women aged 21-29 years (P < .0001). Among women aged 30-64 years, use of cytology alone decreased from 18.9% in 2013 to 8.6% in 2019 (P < .0001), whereas cotesting use increased from 14.9% in 2013 to 19.3% in 2019 (P < .0001). Annual test use for HPV testing alone was below 0.5% in all age groups throughout the study period. Annually, 8.7%-13.6% of women aged 18-20 years received cervical cancer screening. There were persistent differences in screening test use by metropolitan residence and census regions despite similar temporal trends. CONCLUSIONS: Temporal changes in the use of cervical cancer screening tests among commercially insured women track changes in clinical guidelines. Screening test use among individuals younger than 21 years shows that many young women are inappropriately screened for cervical cancer.

RESUMEN

BACKGROUND: New guidelines for managing cervical precancer among women in the United States use risk directly to guide clinical actions for individuals who are being screened. These risk-based management guidelines have previously only been based on risks from a large integrated healthcare system. We present here data representative of women of low income without continuous insurance coverage to inform the 2019 guidelines and ensure applicability. OBJECTIVE: We examined the risks of high-grade precancer after human papillomavirus and cytology tests in underserved women and assessed the applicability of the 2019 guidelines to this population. STUDY DESIGN: We examined cervical cancer screening and follow-up data among 363,546 women enrolled in the Centers for Disease Control and Prevention's National Breast and Cervical Cancer Early Detection Program from 2009 to 2017. We estimated the immediate (prevalent) risks of cervical intraepithelial lesion grade 3 or cancer by using prevalence-incidence mixture models. Risks were estimated for each combination of human papillomavirus and cytology result and were stratified by screening history. We compared these risks with published estimates used in new risk-based management guidelines. RESULTS: Women who were up-to-date with their screening, defined as being screened with cytology within the past 5 years, had immediate risks of cervical intraepithelial neoplasia grade 3 or higher similar to that of women at Kaiser Permanente Northern California, whose data were used to develop the management guidelines. However, women in the Centers for Disease Control and Prevention's National Breast and Cervical Cancer Early Detection Program had greater immediate risks if they were never screened or not up-to-date with their screening. CONCLUSION: New cervical risk-based management guidelines are applicable for underinsured and uninsured women with a low income in the United States who are up-to-date with their screening. The increased risk observed here among women who received human papillomavirus-positive, high-grade cytology results, who were never screened, or who were not up-to-date with their cervical cancer screening, led to a recommendation in the management guidelines for immediate treatment among these women.

RESUMEN

On March 19, 2020, the governor of California issued a statewide stay-at-home order to contain the spread of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19).* The order reduced accessibility to and patient attendance at outpatient medical visits,† including preventive services such as cervical cancer screening. In-person clinic visits increased when California reopened essential businesses on June 12, 2020.§ Electronic medical records of approximately 1.5 million women served by Kaiser Permanente Southern California (KPSC), a large integrated health care system, were examined to assess cervical cancer screening rates before, during, and after the stay-at-home order. KPSC policy is to screen women aged 21-29 years every 3 years with cervical cytology alone (Papanicolaou [Pap] test); those aged 30-65 years were screened every 5 years with human papillomavirus (HPV) testing and cytology (cotesting) through July 15, 2020, and after July 15, 2020, with HPV testing alone, consistent with the latest recommendations from U.S. Preventive Services Task Force.¶ Compared with the 2019 baseline, cervical cancer screening rates decreased substantially during the stay-at-home order. Among women aged 21-29 years, cervical cytology screening rates per 100 person-months declined 78%. Among women aged 30-65 years, HPV test screening rates per 100 person-months decreased 82%. After the stay-at-home order was lifted, screening rates returned to near baseline, which might have been aided by aspects of KPSC's integrated, organized screening program (e.g., reminder systems and tracking persons lost to follow-up). As the pandemic continues, groups at higher risk for developing cervical cancers and precancers should be evaluated first. Ensuring that women receive preventive services, including cancer screening and appropriate follow-up in a safe and timely manner, remains important.

RESUMEN

Population-based cancer registries (PBCR) are vital to the assessment of the cancer burden and in monitoring and evaluating national progress in cervical cancer surveillance and control. Yet the level of their development in countries exhibiting the highest cervical cancer incidence rates is suboptimal, and requires considerable investment if they are to document the impact of WHO global initiative to eliminate cervical cancer as a public health problem. As a starting point we propose a comprehensive cancer surveillance framework, positioning PBCR in relation to other health information systems that are required across the cancer control continuum. The key concepts of PBCR are revisited and their role in providing a situation analysis of the scale and profile of the cancer-specific incidence and survival, and their evolution over time is illustrated with specific examples. Linking cervical cancer data to screening and immunization information systems enables the development of a comprehensive set of measures capable of assessing the short- and long-term achievements and impact of the initiative. Such data form the basis of national and global estimates of the cancer burden and permit comparisons across countries, facilitating decision-making or triggering cancer control action. The initiation and sustainable development of PBCR must be an early step in the scale-up of cervical cancer control activities as a means to ensure progress is successfully monitored and appraised.

RESUMEN

Screening can decrease the burden of breast, cervical, and colorectal cancers. The COVID-19 pandemic led many countries to suspend cancer screening services as part of their response to the pandemic. The International Cancer Screening Network (ICSN) carried out an online survey to assess the effects of the first wave of the COVID-19 pandemic on cancer screening. A 33-item survey was distributed to 834 email addresses to gather information about settings and assess decision-making processes that led to cancer screening suspension. Information about communication, impact on resources, and patient follow-up was collected. Quantitative data was analyzed as frequencies overall and by setting, while a comment section under each survey item captured nuanced details. Responses were recategorized into 66 settings, representing 35 countries. Most settings suspended cancer screening services (n = 60, 90.9%) in March 2020 (n = 45, 68.2%), guided by a government decision (n = 51, 77.3%). Few settings made the decision whether to suspend services based on a preparedness plan (n = 17, 25.8%). In most settings, professionals were reassigned (n = 41, 62.1%) and infrastructure repurposed (n = 35, 53.0%). The first wave of the COVID-19 pandemic has had profound effects on cancer screening worldwide, including the suspension of services in almost all settings. Most settings were unprepared to deal with the scale of the pandemic but demonstrated flexibility in the response. These results contribute to inform, through experiences and lessons learned, the next steps for the global cancer screening community to further evaluate the impact of COVID-19 and prepare for future disruptions.

RESUMEN

Human papillomavirus (HPV) causes most cervical cancers and some cancers of the penis, vulva, vagina, oropharynx, and anus. Cervical precancers can be detected through screening. HPV vaccination with the 9-valent HPV vaccine (9vHPV) can prevent approximately 92% of HPV-attributable cancers (1).* Previous studies have shown lower incidence of HPV-associated cancers in non-Hispanic American Indian and Alaska Native (AI/AN) populations compared with other racial subgroups (2); however, these rates might have been underestimated as a result of racial misclassification. Previous studies have shown that cancer registry data corrected for racial misclassification resulted in more accurate cancer incidence estimates for AI/AN populations (3,4). In addition, regional variations in cancer incidence among AI/AN populations suggest that nationally aggregated data might not adequately describe cancer outcomes within these populations (5). These variations might, in part, result from geographic disparities in the use of health services, such as cancer screening or vaccination (6). CDC analyzed data for 2013-2017 from central cancer registries linked with the Indian Health Service (IHS) patient registration database to assess the incidence of HPV-associated cancers and to estimate the number of cancers caused by HPV among AI/AN populations overall and by region. During 2013-2017, an estimated 1,030 HPV-associated cancers were reported in AI/AN populations. Of these cancers, 740 (72%) were determined to be attributable to HPV types targeted by 9vHPV; the majority were cervical cancers in females and oropharyngeal cancers in males. These data can help identify regions where AI/AN populations have disproportionately high rates of HPV-associated cancers and inform targeted regional vaccination and screening programs in AI/AN communities.

RESUMEN

In the United States, approximately 180,000 patients receive mental health services each day at approximately 4,000 inpatient and residential psychiatric facilities (1). SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19), can spread rapidly within congregate residential settings (2-4), including psychiatric facilities. On April 13, 2020, two patients were transferred to Wyoming's state psychiatric hospital from a private psychiatric hospital that had confirmed COVID-19 cases among its residents and staff members (5). Although both patients were asymptomatic at the time of transfer and one had a negative test result for SARS-CoV-2 at the originating facility, they were both isolated and received testing upon arrival at the state facility. On April 16, 2020, the test results indicated that both patients had SARS-CoV-2 infection. In response, the state hospital implemented expanded COVID-19 infection prevention and control (IPC) procedures (e.g., enhanced screening, testing, and management of new patient admissions) and adapted some standard IPC measures to facilitate implementation within the psychiatric patient population (e.g., use of modified face coverings). To assess the likely effectiveness of these procedures and determine SARS-CoV-2 infection prevalence among patients and health care personnel (HCP) (6) at the state hospital, a point prevalence survey was conducted. On May 1, 2020, 18 days after the patients' arrival, 46 (61%) of 76 patients and 171 (61%) of 282 HCP had nasopharyngeal swabs collected and tested for SARS-CoV-2 RNA by reverse transcription-polymerase chain reaction. All patients and HCP who received testing had negative test results, suggesting that the hospital's expanded IPC strategies might have been effective in preventing the introduction and spread of SARS-CoV-2 infection within the facility. In congregate residential settings, prompt identification of COVID-19 cases and application of strong IPC procedures are critical to ensuring the protection of other patients and staff members. Although standard guidance exists for other congregate facilities (7) and for HCP in general (8), modifications and nonstandard solutions might be needed to account for the specific needs of psychiatric facilities, their patients, and staff members.

RESUMEN

India's cervical cancer screening program was launched in 2016. We evaluated baseline facility readiness using nationally representative data from the 2012-13 District Level Household and Facility Survey on 4 tiers of the public health care system - 18,367 sub-health centres (SHCs), 8540 primary health centres (PHCs), 4810 community health centres and 1540 district/sub-divisional hospitals. To evaluate facility readiness we used the Improving Data for Decision Making in Global Cervical Cancer Programmes toolkit on six domains - potential staffing, infrastructure, equipment and supplies, infection prevention, medicines and laboratory testing, and data management. Composite scores were created by summing responses within domains, standardizing scores across domains at each facility level, and averaging across districts/states. Overall, readiness scores were low for cervical cancer screening. At SHCs, the lowest scores were observed in 'infrastructure' (0.55) and 'infection prevention' (0.44), while PHCs had low 'potential staffing' scores (0.50) due to limited manpower to diagnose and treat (cryotherapy) potential cases. Scores were higher for tiers conducting diagnostic work-up and treatment/referral. The highest scores were in 'potential staffing' except for PHCs, while the lowest scores were in 'infection & prevention' and 'medicines and laboratory'. Goa and Maharashtra were consistently among the top 5 ranking states for readiness. Substantial heterogeneity in facility readiness for cervical cancer screening spans states and tiers of India's public healthcare system. Infrastructure and staffing are large barriers to screening at PHCs, which are crucial for referral of high-risk patients. Our results suggest focus areas in cervical cancer screening at the district level for policy makers.

RESUMEN

OBJECTIVE: The 2019 ASCCP Risk-Based Management Consensus Guidelines present a paradigm shift from results- to risk-based management. Patient and provider factors can affect guideline adoption. We sought feedback from stakeholders to inform guideline development. MATERIALS AND METHODS: To solicit provider feedback, we surveyed attendees at the 2019 ASCCP annual meeting regarding readiness to adopt proposed changes and used a web-based public comment period to gauge agreement/disagreement with preliminary guidelines. We elicited patient feedback via a brief survey on preferences around proposed recommendations for treatment without biopsy. Surveys and public comment included both closed-ended and free-text items. Quantitative results were analyzed using descriptive statistics; qualitative results were analyzed using content analysis. Results were incorporated into guideline development in real time. RESULTS: Surveys indicated that 98% of providers currently evaluate their patients' past results to determine management; 88% felt formally incorporating history into management would represent an improvement in care. Most providers supported expedited treatment without biopsy: 22% currently perform expedited treatment and 60% were willing to do so. Among patients, 41% preferred expedited treatment, 32% preferred biopsy before treatment, and the remainder were undecided. Responses from the public comment period included agreement/disagreement with preliminary guidelines, reasons for disagreement, and suggestions for improvement. CONCLUSIONS: Stakeholder feedback was incorporated into the development of the 2019 ASCCP Risk-Based Management Consensus Guidelines. Proposed recommendations with less than two-thirds agreement in the public comment period were considered for revision. Findings underscore the importance of stakeholder feedback in developing guidelines that meet the needs of patients and providers.

RESUMEN

BACKGROUND: Since the mid-1980s, the burden of liver cancer in the United States has doubled, with 31,411 new cases and 24,698 deaths occurring in 2014. Foreign-born individuals may be more likely to die of liver cancer than individuals in the general US-born population because of higher rates of hepatitis B infection, a low socioeconomic position, and language barriers that limit the receipt of early cancer detection and effective treatment. METHODS: To determine whether liver cancer mortality rates were higher among foreign-born individuals versus US-born individuals in the United States, population-based cancer mortality data were obtained from the National Center for Health Statistics of the Centers for Disease Control and Prevention. Annual population estimates were obtained from the US Census Bureau's American Community Survey. Age-adjusted mortality rates and rate ratios (RRs) for liver cancer stratified by birth place were calculated, and the average annual percent change (AAPC) was used to evaluate trends. RESULTS: A total of 198,557 deaths from liver and intrahepatic bile duct cancer were recorded during 2005-2014, and 16% occurred among foreign-born individuals. Overall, foreign-born individuals had a 24% higher risk of liver cancer mortality than US-born individuals (RR, 1.24; 95% confidence interval [CI], 1.22-1.25). Foreign-born individuals did not have any significant changes in liver cancer mortality rates overall, but among US-born individuals, liver cancer mortality rates significantly increased (AAPC, 2.7; 95% CI, 2.1-3.3). CONCLUSIONS: Efforts that address the major risk factors for liver cancer are needed to help to alleviate the health disparities observed among foreign-born individuals and reverse the increasing trend observed in the US-born population.
