RESUMEN

BACKGROUND: The guidelines for managing abnormal cervical cancer screening tests changed from a results-based approach in 2012 to a risk-based approach in 2019. OBJECTIVE: We estimated the cost-effectiveness of the 2019 management guidelines and the changes in resource utilization moving from 2012 to 2019 guidelines. STUDY DESIGN: We utilized a previously published model of cervical cancer natural history and screening to estimate and compare the lifetime costs and the number of screens, colposcopies, precancer treatments, cancer cases, and cancer deaths associated with the 2012 vs 2019 management guidelines. We assessed these guidelines under the scenarios of observed screening practice and perfect screening adherence to 3-year cytology starting at age 21, with a switch to either 3-year or 5-year cytology plus human papillomavirus cotesting at age 30. In addition, we estimated the lifetime costs and life years to determine the cost-effectiveness of shifting to the 2019 management guidelines. RESULTS: Under the assumptions of both observed screening practice and perfect screening adherence with a strategy of 3-year cytology at ages 21 to 29 and switching to 3-year cotesting at age 30, the management of the screening tests according to the 2019 guidelines was less costly and more effective than the 2012 guidelines. For 3-year cytology screening at ages 21 to 29 and switching to 5-year cotesting at age 30, the 2019 guidelines were more cost-effective at a willingness-to-pay threshold of $100,000 per life year gained. Across all scenarios, the 2019 management guidelines were associated with fewer colposcopies and cancer deaths. CONCLUSION: Our model-based analysis suggests that the 2019 guidelines are more effective overall and also more cost-effective than the 2012 guidelines, supporting the principle of "equal management of equal risks."

RESUMEN

Liquid-based preparation (LBP) cytology is commonly used in most laboratories these days due to its convenience and reliable results for the cervical cancer screening program. The PathTezt™ Liquid-based Pap smear is a second-generation LBP, which uses a filter-based concentration technique in processing the sample. OBJECTIVE: This study was done to evaluate the cellular fixation, morphology, quality of smear in gynae cytology, and diagnostic interpretation of cervical cytological smears produced by the PathTezt liquid-based processor. MATERIALS AND METHODS: A total of 400 pap smear samples were taken and processed using the PathTezt 2000 processor. The slides were evaluated in terms of sample adequacy, percentage of the circle covered by epithelial cells, cellular distribution, obscuring factors, and cell fixation. RESULTS: About 95.25% (381) of the samples were satisfactory for the evaluation. In 19 (4.75%) of the samples, epithelial cells covered less than 50% of the circle. A sample with good cellular distribution was seen in 92% of the cases, while 354 (88.5%) samples showed minimal inflammatory background. Almost all the smears (95.75%) had no erythrocytes in the background. All smears showed good quality fixation features toward nuclear, cytoplasm, and microorganisms. The total performance rate was 99%. CONCLUSION: Although the PathTezt liquid-based processor is still new compared to other first-generation LBP, the smears produced by this method were of high quality and it was cost-effective.

RESUMEN

OBJECTIVE: It has been proposed that cervical cancer screening should be continued in women with previous abnormal results or irregular attendance. We examined the coverage and factors that might influence cervical testing beyond the age range of the organized cervical screening programme in Finland. The national programme invites women in every five years least until the age of 60. After the stopping age, only opportunistic service is available. METHODS: Data on cervical testing were collected from the Mass Screening Registry and providers of opportunistic Pap/HPV-testing and were linked with information on socio-economic variables. The study included 373,353 women who had at least one invitation to the national screening programme between ages 50-60 years, and who were aged 65-74 years in the follow-up period 2006-2016. Multivariable binomial regression models were conducted to determine associations. RESULTS: Altogether 33% of the study population had been tested at least once at ages 65-74 years. Previous regular screening attendance (adjRR 1.70; 95% CI 1.67-1.73) and earlier abnormal results (adjRR 2.08; 95% CI 2.04-2.12) were most clearly related to higher testing adherence at older age. Other factors related to higher testing adherence were urban area of residence, domestic mother tongue, high education level, and high socio-economic status. CONCLUSION: Testing at older age was frequent with normal results, whereas only a small proportion of women with earlier abnormal results or irregular attendance were tested. The upper age limit of the national programme should be raised to 65 years, and the invitations thereafter should be targeted to selected high-risk groups.

RESUMEN

OBJECTIVE: To report a modelling study using local health care costs and epidemiological inputs from a population-based program to access the cost-effectiveness of adopting hrHPV test. METHODS: A cost-effectiveness analysis based on a microsimulation dynamic Markov model. Data and costs were based on data from the local setting and literature review. The setting was Indaiatuba, Brazil, that has adopted the hrHPV test in place of cytology since 2017. After calibrating the model, one million women were simulated in hypothetical cohorts. Three strategies were tested: cytology to women aged 25 to 64 every three years; hrHPV test to women 25-64 every five years; cytology to women 25-29 years every three years and hrHPV test to women 30-64 every five years (hybrid strategy). Outcomes were Quality-adjusted life-years (QALY) and Incremental Cost-Effectiveness Ratio (ICER). RESULTS: The hrHPV testing and the hybrid strategy were the dominant strategies. Costs were lower and provided a more effective option at a negative incremental ratio of US$ 37.87 for the hybrid strategy, and negative US$ 6.16 for the HPV strategy per QALY gained. Reduction on treatment costs would influence a decrease in ICER, and an increase in the costs of the hrHPV test would increase ICER. CONCLUSIONS: Using population-based data, the switch from cytology to hrHPV testing in the cervical cancer screening program of Indaiatuba is less costly and cost-effective than the old cytology program.

RESUMEN

BACKGROUND: African-American women in the United States have an elevated risk of cervical cancer incidence and mortality. In the Mississippi Delta, cervical cancer disparities are particularly stark. METHODS: We conducted a micro-costing study alongside a group randomized trial that evaluated the efficacy of a patient-centered approach ("Choice" between self-collection at home for HPV testing or current standard of care within the public health system in Mississippi) versus the current standard of care ["Standard-of-care screening," involving cytology (i.e., Pap) and HPV co-testing at the Health Department clinics]. The interventions in both study arms were delivered by community health workers (CHW). Using cost, screening uptake, and colposcopy adherence data from the trial, we informed a mathematical model of HPV infection and cervical carcinogenesis to conduct a cost-effectiveness analysis comparing the "Choice" and "Standard-of-care screening" interventions among un/underscreened African-American women in the Mississippi Delta. RESULTS: When each intervention was simulated every 5 years from ages 25 to 65 years, the "Standard-of-care screening" strategy reduced cancer risk by 6.4% and was not an efficient strategy; "Choice" was more effective and efficient, reducing lifetime risk of cervical cancer by 14.8% and costing $62,720 per year of life saved (YLS). Screening uptake and colposcopy adherence were key drivers of intervention cost-effectiveness. CONCLUSIONS: Offering "Choice" to un/underscreened African-American women in the Mississippi Delta led to greater uptake than CHW-facilitated screening at the Health Department, and may be cost-effective. IMPACT: We evaluated the cost-effectiveness of an HPV self-collection intervention to reduce disparities.

RESUMEN

BACKGROUND: Most cost-effectiveness analyses in the context of cervical cancer prevention involve the use of mathematical models to simulate HPV infection, cervical disease and prevention strategies. However, it is common for professionals who would need to perform these analyses to not be familiar with the models. This work introduces the Online Cost-Effectiveness ANalysis tool, featuring an easy-to-use web interface providing health professionals, researchers and decision makers involved in cervical cancer prevention programmes with a useful instrument to conduct complex cost-effectiveness analyses, which are becoming an essential tool as an approach for supporting decision-making that involves important trade-offs. RESULTS: The users can run cost-effectiveness evaluations of cervical cancer prevention strategies without deep knowledge of the underlying mathematical model or any programming language, obtaining the most relevant costs and health outcomes in a user-friendly format. The results provided by the tool are consistent with the existing literature. CONCLUSIONS: Having such a tool will be an asset to the cervical cancer prevention community, providing researchers with an easy-to-use instrument to conduct cost-effectiveness analyses.

RESUMEN

BACKGROUND: The causal relationship between high-risk (hr) HPV infection and precancerous lesions or cervical cancer has led to the development of strategies to increase screening performance and prevent this cancer. The increased sensitivity of DNA-HPV testing compared to cervical cytology favors DNA-HPV testing as a primary screening test. Cervical cancer screening in Brazil is opportunistic, and this cancer remains a considerable health problem with a high proportion of diagnoses in advanced stages. This paper aims to describe the design and implementation of the Cervical Cancer Screening Program with primary DNA-HPV testing (CCSP-HPV) planned for Indaiatuba City (SP), Brazil; the strategies to achieve higher population coverage; and a study protocol for cost-effectiveness analyses. METHODS: The CCSP-HPV was designed based on successful guidelines that replaced cervical cytology-based screening by the DNA-HPV test performed at 5-year intervals. The screening will be performed for the female population aged 25-64 years cared for by the public health system and aim to reach 80% coverage after completing the first round. The chosen DNA-HPV test detects 14 hr-HPV types and genotypes HPV-16 and 18. All women with a negative test will be reassessed after five years. Women showing a positive test for HPV-16 and/or 18 will be referred for colposcopy. Those showing the other 12 hr-HPV types will be tested by cytology, and if any abnormality is detected, they will also be referred for colposcopy. The histopathologic evaluation will be reviewed by a pathologist panel and aided by p16 immunohistochemistry. A cost-effectiveness analysis will be performed by a Markov model comparing the cost of the new program and the screening performed by conventional cytology five years prior (2011-2016). DISCUSSION: The new screening program is considered a breakthrough for public health regarding cervical cancer, which is the third leading cause of cancer death among Brazilian women. Achieving at least 80% coverage will have the possibility to change this scenario. The proposed program will provide a modern cervical cancer screening method for women, and information about cost-effectiveness will help other similar places support the decision of implementing cervical cancer screening using the DNA-HPV test.

RESUMEN

Appropriately matching preventive health services and screenings with patient risk is an important quality indicator. Adherence by both providers and patients to cervical cancer screening guidelines has been inconsistent, resulting in overscreening and increased costs. This study examined the prevalence of cervical cancer overscreening following changes in screening guidelines in a wellness registry database. Cervical cancer overscreening after guideline implementation decreased for 18- to 20-year-old patients from 26.8% to 24.8% (P < .001) and increased for those aged 65 years and older from 11.1% to 12.5% (P = .0005). Black race, Hispanic ethnicity, Medicaid insurance, and the presence of a personal health record were associated with overscreening. Reliability and accuracy of data are a concern when data intended for one purpose, such as clinical care, are used for research. Correctly identifying screening tests in the electronic health record is important so that appropriate screening can be reliably assessed. In this study on the prevalence of cervical cancer overscreening, we used a focused chart review to identify whether screening Pap tests were accurately identified in the electronic medical record. Pap tests were correctly identified as screening in 85% of those aged 18 to 20, and in 74% of those aged 65 and older.

RESUMEN

Until 2018, cervical cancer screening in France was an unorganized individual screening, with the exception of some pilot programs in some territories. We aimed to assess, before the implementation of organized cervical cancer screening and human papillomavirus (HPV) nonavalent vaccine introduction in the vaccination schedule in 2018, (i) the individual cervical cancer screening coverage, (ii) the management of squamous intraepithelial lesions (SIL) and (iii) the related costs. We used the Système National des Données de Santé (SNDS) (Echantillon Généraliste de Bénéficiaires [EGB] and Programme de Médicalisation des systèmes d'information [PMSI]) to assess the cervical screening coverage rate in France between January 1st, 2012 and December 31st, 2014, and to describe diagnostic investigations and therapeutic management of SIL in 2013. After extrapolation to the general population, a total of 10,847,814 women underwent at least one smear test over the 3-year study period, corresponding to a coverage rate of 52.4% of the women aged 25 to 64 included. In 2013, 126,095 women underwent HPV test, 327,444 women underwent colposcopy, and 9,653 underwent endocervical curettage; 31,863 had conization and 12,162 had laser ablation. Besides, 34,067 women experienced hospital stays related to management of SIL; 25,368 (74.5%) had high-grade lesions (HSIL) and 7,388 (21.7%) low-grade lesions (LSIL). Conization was the most frequent in-hospital therapeutic procedure: 89.5% (22,704) of women with an in-hospital procedure for HSIL and 64.7% (4,781) for LSIL. Mean cost of smear test, colposcopy and HPV tests were around 50€. Total cost for hospital stays in 2013 was estimated at M41€, or a mean cost of 1,211€ per woman; 76% were due to stays with HSIL. This study highlights the low coverage rate of individual cervical cancer screening and a high burden related to SIL management.

RESUMEN

In Lithuania, cytological screening of cervical cancer (CC) is largely opportunistic. Absence of standardized systematic invitation practice might be the reason for low participation rates. The study aimed to assess the cost-effectiveness of systematic invitation approach in CC screening programme from the perspective of a healthcare provider. A decision tree was used to compare an opportunistic invitation by a family doctor, a personal postal invitation letter with appointment time and place, and a personal postal invitation letter with appointment time and place with one reminder letter. Cost-effectiveness was defined as an incremental cost-effectiveness ratio (ICER) per one additionally screened woman and per one additional abnormal Pap smear test detected. The ICER of one personal postal invitation letter was €9.67 per one additionally screened woman and €55.21 per one additional abnormal Pap smear test detected in comparison with the current screening practice. The ICER of a personal invitation letter with an additional reminder letter compared to one invitation letter was €13.47 and €86.88 respectively. Conclusions: A personal invitation letter approach is more effective in increasing the participation rate in CC screening and the number of detected abnormal Pap smears; however, it incurs additional expenses compared with current invitation practice.

RESUMEN

OBJECTIVE: To describe cervical cancer screening participation among women in Taiwan under its population-based screening policy and to estimate the economic burden of disease attributable to avoidable disparities in cervical cancer (CC) screening. METHODS: We identified a nationally-representative sample of females aged 30 years or above who were eligible for Pap smear testing in Taiwan from 1 January to 31 December 2013. An administrative database with detailed claims of health care utilization under the universal coverage health care system was used. Socioeconomic position of the female subjects was defined using the occupation classification, and two groups were specifically identified: general (O1) and low-income (O5) groups. Differences in screening rate, CC prevalence, and CC-attributable deaths were assessed between the two groups. Economic consequences as a result of screening inequalities were estimated using actual total health care spending (health care expenditure), monetary value per life-year and years of life lost for ill health and screening disparities (health as consumption good), and productivity losses alongside costs of social benefits (health as capital good). RESULT: A total of 301,057 enrolled females aged 30 years and older eligible for screening were identified. Overall, 3-year and 1-year screening rates among all subjects were 0.601 and 0.372, respectively. Impact of observed differences in screening translated to US$59,568 of health care spending in one year, 90.4% of which was specific to hospital admissions. When we viewed health as a consumption good and capital good, the impact of screening disparity on health losses through CC would be equivalent to US$78,095 and US$190,868, respectively. CONCLUSION: Forgone health and economic benefits associated with inequalities in CC screening uptake can be considerable in productive women.

RESUMEN

OBJECTIVE: To determine preferences for HPV-based cervical cancer screening among South African women. METHODS: A discrete choice experiment survey was conducted among 298 women who attended two public-sector clinics in South Africa from February 1 to May 31, 2018. Participants chose between hypothetical screening scenarios: method of swab collection (self or provider); timing of treatment (same day or return visit); type of clinic (static or mobile); cost of services (US $0 or US $4); and time spent at the clinic (30, 60, or 120 minutes). A logistic regression model was generated to evaluate the importance of each attribute. A market simulation analysis was performed to determine potential uptake of the various screening strategies. RESULTS: The participants expressed strong preferences for free services (ß=0.50; P<0.001) and same-day HPV testing and treatment (ß=0.40; P<0.001). The market simulation indicated that 83.8% of women would be willing to undergo screening if services were free; the swab was collected by the provider; and treatment was offered at a return visit. Including same-day testing and treatment in the model increased uptake to 96.4%. CONCLUSION: Offering same-day HPV testing and treatment could substantially improve uptake of cervical cancer screening in the South African public healthcare sector.

RESUMEN

OBJECTIVE: About 30% of women who are eligible for cervical cancer (CC) screening remain un-screened or under-screened in Switzerland. HPV testing on self-collected vaginal samples (Self-HPV) has shown to be more sensitive than cytology while also reaching non-attendees. The objective of this study was to explore the cost-effectiveness of offering Self-HPV to non-attendees in Switzerland. METHODS: A recursive decision-tree with one-year cycles was used to model the life-long natural HPV history. Markov cohort simulations were used to assess the expected outcomes from the model. The outcomes of three strategies were compared with the absence of screening: Self-HPV and triage with colposcopy (Self-HPV/colpo), Self-HPV and triage with Pap cytology (Self-HPV/PAP), cytological screening and triage with HPV (PAP/HPV). Sensitivity analyses for the key parameters of the model were conducted to check the robustness of findings. RESULTS: Offering a Self-HPV screening to non-attendees could prevent 90% of CC and 94% of CC-related deaths in the study population. The current cytology-based program could reduce by 83% the number of CC cases and by 88% the number of CC-related deaths over the population's lifetime. Compared to the absence of screening, incremental cost-effectiveness ratios (ICER) were estimated to be, per saved Quality Adjusted Life Year (QALY), 12413US$ for the strategy Self-HPV/colpo, 11138US$ for the strategy Self-HPV/Pap and 22488US$ for the strategy PAP/HPV. CONCLUSIONS: Offering Self-HPV as a CC screening strategy to non-attendees in Switzerland is a cost-effective solution that is associated with a reduction of CC cases and related deaths. Self-HPV is more cost-effective than the currently used cytology-based screening.

RESUMEN

OBJECTIVES: Logistical and economic issues make traditional cytology-based cervical cancer screening challenging in developing countries. Alternative, cost-effective, screening strategies must be developed to screen millions of women in resource-poor countries such as Cambodia. DESIGN: A prospective cohort study during which all women underwent four cervical cancer screening methods: (1) self-sampled human papilloma virus (HPV) testing (careHPV system), (2) clinician-collected HPV testing, (3) visualization with acetic acid (VIA) and (4) digital colposcopy (DC) with the Enhanced Visual Assessment System (EVA). SETTING: A referral hospital in Phnom Penh, Cambodia. PARTICIPANTS: Two hundred and fifty Cambodian women (129 HIV+, 121 HIV-). Subjects were recruited from the National Center for HIV/AIDS Dermatology and sexually transmitted disease (STD) cohort, the Sihanouk Hospital Center of Hope's Rural Outreach Teams and the Pochentong Medical Center. RESULTS: Fifty six of the 250 (22.4%) patients tested positive for high-risk HPV (hrHPV+). Thirty seven of the 129 HIV+ women were hrHPV+ (28.6%) whereas 19/121 HIV- women were hrHPV+ (15.7%) p=0.0154. Self-sampling HPV specimens identified 50/56 (89%) whereas physician-collected specimens identified 45/56 (80%) p=0.174. 95.2% of the patients felt comfortable obtaining HPV self-samples. Thirty seven of 250 women were VIA+. Thirty of 37 VIA+ women underwent confirmatory biopsies for cervical intraepithelial neoplasia (CIN) (26 CIN1, 4 CIN2+). The rate of confirmed dysplasia in the HIV+ group was 20/129 (15.5%) compared with 10/121 (8.26%) in HIV- women p=0.0291. The contemporaneous physician impressions of the DC images accurately differentiated between CIN1 and CIN2+ lesions in all 30 women having confirmatory biopsies. CONCLUSIONS: The results of this study suggest potential modifications of the current cervical screening strategy that is currently being employed in Cambodia. The first step in this new strategy would be self-swabbing for hrHPV. Subsequently, hrHPV+ patients would have DC and immediate treatment based on colposcopic findings: cryotherapy for suspected CIN1 and loop electrosurgical excision procedure (LEEP) for suspected CIN2+.

RESUMEN

OBJECTIVE: This study compared the screening capacities and cost-effectiveness of the human papillomavirus (HPV) test versus cervicography as an adjunctive test to Papanicolaou (Pap) cytology to detect high-grade cervical neoplasia in Korea, a country with a high prevalence of cervical cancer. STUDY DESIGN: Of 33,531 Korean women who underwent cervicography as a screening test for cervical cancer between January 2015 and December 2016, we retrospectively analyzed the records of 4117 women who simultaneously or subsequently underwent Pap cytology, an HPV test, cervicography, and colposcopically directed biopsy. At a threshold of cervical intraepithelial neoplasia grade 2 or worse (CIN2+), based on colposcopic biopsy, we compared the diagnostic capacities and cost-effectiveness of these screening tools. RESULTS: The CIN2+ prevalence was 10.8% (446 of 4117 women) and the positive rate of high-risk HPV was 61.0% (2511 of 4117 women). Cervicography as an adjunctive to Pap cytology was a more sensitive test (97.5% vs 93.7%) with a higher odds ratio (15.65 vs 5.86) than the HPV test for detection of CIN2+ (P-value = 0.003). Moreover, the cost of cervicography co-testing was 23% less than that of HPV co-testing, decreasing the cost per patient with CIN2+ lesions from $1474 to $1135. CONCLUSION: Cervicography and Pap co-testing had superior screening capacity and cost-effectiveness for detection of preinvasive cervical lesions than HPV and Pap co-testing and may be an effective and cost-saving screening strategy in clinical practice in country with a high prevalence of cervical cancer.

RESUMEN

BACKGROUND: The Rio Grande Valley (RGV) and Laredo regions located along the Texas-Mexico border consist of seven counties with a population of approximately 1.5 million people and a high uninsured rate (33.5%). Cervical cancer mortality in these border counties is approximately 30% higher than the rest of Texas. The RGV and Laredo areas were studied to better understand the state of access to cervical cancer prevention services along the Texas-Mexico border. METHODS: Data on the population served and the services provided were analyzed to determine the gap between cervical cancer screenings recommended versus those received. Through interviews, we gathered the perspectives of 16 local stakeholders regarding cervical cancer screening for underserved individuals in the region. FINDINGS: It is estimated that 69,139 uninsured women aged 21-64 years in the RGV/Laredo per year are recommended to undergo cervical cancer screening with Papanicolaou (Pap) and/or human papillomavirus (HPV) testing, but only 8941 (12.9%) Pap tests are being performed by the Federally Qualified Health Center (FQHC) serving uninsured women in these regions. Systemic barriers identified include insufficient provider clinical capacity, the high cost of healthcare, and uncertainty about government funding sources. Patient barriers identified include inadequate knowledge on navigating the local healthcare system, low health literacy, lack of money and childcare, an inability to miss work, limited transportation, and fear of deportation. CONCLUSION: Decreasing the disparity between cervical cancer screening services provided and those recommended requires addressing the barriers, identified by local experts, which prevent uninsured women from accessing care. These challenges are being addressed through ongoing programs and collaborations.

RESUMEN

BACKGROUND: Current cervical cancer screening guidelines recommend a Pap test every 3 years for women age 21-65 years, or for women 30-65 years who want to lengthen the screening interval, a combination of Pap test and high-risk human papilloma virus testing (co-testing) every 5 years. Little population-based data are available on human papilloma virus test utilization and human papilloma virus infection rates. The objective of this study was to examine the patient-level, cervical cancer screening, and area-level factors associated with human papilloma virus testing and infection among a diverse sample of uninsured and underinsured women enrolled in the New Jersey Cancer Early Education and Detection (NJCEED) Program. METHODS: We used data for a sample of 50,510 uninsured/underinsured women, age ≥ 29 years, who screened for cervical cancer through NJCEED between January 1, 2009 and December 31, 2015. Multivariable logistic regression models were used to estimate associations between ever having a human papilloma virus test or a positive test result, and individual- (age, race/ethnicity, birthplace) and area-level covariates (% below federal poverty level, % minority, % uninsured), and number of screening visits. RESULTS: Only 26.6% (13,440) of the sample had at least one human papilloma virus test. Among women who underwent testing, 13.3% (1792) tested positive for human papilloma virus. Most women who were positive for human papilloma virus (99.4%) had their first test as a co-test. Human papilloma virus test utilization and infection were significantly associated with age, race/ethnicity, birthplace (country), and residential area-level poverty. Rates of human papilloma virus testing and infection also differed significantly across counties in the state of New Jersey. CONCLUSIONS: These findings suggest that despite access to no-cost cervical cancer screening for eligible women, human papilloma virus test utilization was relatively low among diverse, uninsured and underinsured women in New Jersey, and test utilization and infection were associated with individual-level and area-level factors.

RESUMEN

This study explored how structural and cultural forces work together with psychological and communication factors in influencing Pap test compliance among Latinas in Los Angeles County, a group who face health disparities related to cervical cancer screening, incidence and mortality. By adopting a multilevel approach to obtain a grounded understanding of this issue, this work revealed that structural barriers, fatalism, religious service attendance, perceived susceptibility, perceived costs, and cues to action from health care providers are all associated with Pap test compliance. Financial barriers also influence compliance, with underinsurance having a stronger negative impact compared to no insurance at all. These findings provide insights into how communication efforts can be strategically designed to address both individual- and system-level barriers to promote health-seeking behaviors among Latinas, and potentially among other population groups experiencing health disparities due to similar reasons.

RESUMEN

Cervical cancer affects women in their reproductive ages. Screening is an important secondary prevention strategy. The long process of carcinogenic transformation from human papillomavirus (HPV) infection to invasive cancer provides ample opportunities to detect the disease at a stage when treatment is highly effective. Suitable screening tests are cytology, visual inspection after acetic acid application and HPV detection tests. Evidence of effectiveness of the tests to reduce cervical cancer mortality and the cost-effectiveness of screening programs have been demonstrated. Cervical intraepithelial neoplasia grade 2 and grade 3 are the high-grade cervical cancer precursors and need to be treated. Treatment is safe and effective with ablative or excisional techniques. The World Health Organization recommends screening women at least once in a lifetime between 30 and 49 years of age and ensuring effective treatment of the detected abnormalities. Combination of HPV vaccination and population-based screening will be instrumental in eliminating cervical cancer.
