Enhanced cervical cancer and HIV interventions reduce the disproportionate burden of cervical cancer cases among women living with HIV: A modeling analysis. PLoS One 2024; 19:e0301997. [PMID: 38781268 PMCID: PMC11115290 DOI: 10.1371/journal.pone.0301997] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 03/26/2024] [Indexed: 05/25/2024] Open
Abstract
INTRODUCTION Women living with HIV experience heightened risk of cervical cancer, and over 50% of cases in Southern Africa are attributed to HIV co-infection. Cervical cancer interventions tailored by HIV status delivered with HIV antiretroviral therapy (ART) for treatment can decrease cancer incidence, but impact on HIV-related disparities remains understudied. METHODS Using a dynamic model calibrated to KwaZulu-Natal, South Africa, we projected HIV prevalence, cervical cancer incidence, and proportion of cancer cases among women living with HIV between 2021-2071. Relative to the status quo of moderate intervention coverage, we modeled three additive scenarios: 1) ART scale-up only; 2) expanded human papillomavirus (HPV) vaccination, screening, and treatment; and 3) catch-up HPV vaccination and enhanced screening for women living with HIV. RESULTS Under the status quo, HIV prevalence among women aged 15+ decreased from a median of 35% [Uncertainty Range (UR): 26-42%] in 2021 to 25% [19-34%] in 2071. The proportion of cervical cancer cases that were women living with HIV declined from 73% [63-86%] to 58% [47-74%], but incidence remained 4.3-fold [3.3-5.7] that of women without HIV. ART scale-up reduced HIV prevalence in 2071, but increased the incidence rate ratio to 5.2 [3.7-7.3]. Disparities remained after expanding cancer interventions for all women (incidence rate ratio: 4.8 [3.6-7.6]), while additional catch-up HPV vaccination and screening for women living with HIV decreased the incidence rate ratio to 2.7 [1.9-3.4] in 2071. CONCLUSIONS Tailored cervical cancer interventions for women living with HIV can counteract rising cancer incidence incurred by extended life expectancy on ART and reduce disparate cancer burden.

Toniolo J, Ngoungou EB, Preux PM, Beloni P. Role and knowledge of nurses in the management of non-communicable diseases in Africa: A scoping review. PLoS One 2024; 19:e0297165. [PMID: 38635822 PMCID: PMC11025970 DOI: 10.1371/journal.pone.0297165] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Accepted: 12/30/2023] [Indexed: 04/20/2024] Open
Abstract
BACKGROUND 31.4 million people in low- and middle-income countries die from chronic diseases annually, particularly in Africa. To address this, strategies such as task-shifting from doctors to nurses have been proposed and have been endorsed by the World Health Organization as a potential solution; however, no comprehensive review exists describing the extent of nurse-led chronic disease management in Africa. AIMS This study aimed to provide a thorough description of the current roles of nurses in managing chronic diseases in Africa, identify their levels of knowledge, the challenges, and gaps they encounter in this endeavor. METHODS We performed a scoping review following the key points of the Cochrane Handbook, and two researchers independently realized each step. Searches were conducted using five databases: MEDLINE, PyscINFO, CINAHL, Web of Science, and Embase, between October 2021 and April 2023. A descriptive analysis of the included studies was conducted, and the quality of the studies was assessed using the Downs and Black Scale. RESULTS Our scoping review included 111 studies from 20 African countries, with South Africa, Nigeria, and Ghana being the most represented. Findings from the included studies revealed varying levels of knowledge. Nurses were found to be actively involved in managing common chronic diseases from diagnosis to treatment. Facilitating factors included comprehensive training, close supervision by physicians, utilization of decision trees, and mentorship. However, several barriers were identified, such as a shortage of nurses, lack of essential materials, and inadequate initial training. CONCLUSION There is significant potential for nurses to enhance the screening, diagnosis, and treatment of chronic diseases in Africa. Achieving this requires a combination of rigorous training and effective supervision, supported by robust policies. To address varying levels of knowledge, tailored training programs should be devised. Further research is warranted to establish the effectiveness of nurse-led interventions on population health outcomes.

Real-World Cervical Cancer Screening Uptake and Predictors of Visual Inspection With Acetic Acid Positivity Among Women Living With HIV in Care Programs in Western Kenya. JCO Glob Oncol 2024; 10:e2300311. [PMID: 38359369 PMCID: PMC10881085 DOI: 10.1200/go.23.00311] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 11/15/2023] [Accepted: 12/08/2023] [Indexed: 02/17/2024] Open
Abstract
PURPOSE To achieve the WHO cervical cancer elimination targets, countries globally must achieve 70% cervical cancer screening (CCS) coverage. We evaluated CCS uptake and predictors of screening positive at two public HIV care programs in western Kenya. METHODS From October 2007 to February 2019, data from the Family AIDS Care and Education Services (FACES) and Academic Model Providing Access to Healthcare (AMPATH) programs in western Kenya were analyzed. The study population included women age 18-65 years enrolled in HIV care. Screening uptake was calculated annually and overall, determining the proportion of eligible women screened. Multivariate logistic regression assessed predictors of positive screening outcomes. RESULTS There were 57,298 women living with HIV (WLWHIV) eligible for CCS across both programs during the study period. The mean age was 31.4 years (IQR, 25.9-37.8), and 39% were on antiretroviral therapy (ART) at the first CCS-eligible visit. Of all eligible women, 29.4% (95% CI, 29.1 to 29.8) underwent CCS during the study period, 27.0% (95% CI, 26.5 to 27.4) in the AMPATH program, and 35.6% (95% CI, 34.9 to 36.4) in the FACES program. Annual screening uptake varied greatly in both programs, with coverage as low as 1% of eligible WLWHIV during specific years. Age at first screening, CD4 count within 90 days of screening, current use of ART, and program (AMPATH v FACES) were each statistically significant predictors of positive screening. CONCLUSION CCS uptake at two large HIV care programs in Kenya fell short of the WHO's 70% screening target. Screening rates varied significantly on the basis of the availability of funding specific to CCS, reflecting the limitations of vertical funding programs.

[PMID: 38237096 PMCID: PMC10805431 DOI: 10.1200/go.23.00238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Revised: 08/22/2023] [Accepted: 10/18/2023] [Indexed: 01/23/2024] Open
Abstract
PURPOSE Cancer deaths in low- and middle-income countries (LMICs) will nearly double by 2040. Available evidence-based interventions (EBIs) for cancer prevention and early detection can reduce cancer-related mortality, yet there is a lack of evidence on effectively scaling these EBIs in LMIC settings. METHODS We conducted a scoping review to identify published literature from six databases between 2012 and 2022 that described efforts for scaling cancer prevention and early detection EBIs in LMICs. Included studies met one of two definitions of scale-up: (1) deliberate efforts to increase the impact of effective intervention to benefit more people or (2) an intervention shown to be efficacious on a small scale expanded under real-world conditions to reach a greater proportion of eligible population. Study characteristics, including EBIs, implementation strategies, and outcomes used, were summarized using frameworks from the field of implementation science. RESULTS This search yielded 3,076 abstracts, with 24 studies eligible for inclusion. Included studies focused on a number of cancer sites including cervical (67%), breast (13%), breast and cervical (13%), liver (4%), and colon (4%). Commonly reported scale-up strategies included developing stakeholder inter-relationships, training and education, and changing infrastructure. Barriers to scale-up were reported at individual, health facility, and community levels. Few studies reported applying conceptual frameworks to guide strategy selection and evaluation. CONCLUSION Although there were relatively few published reports, this scoping review offers insight into the approaches used by LMICs to scale up cancer EBIs, including common strategies and barriers. More importantly, it illustrates the urgent need to fill gaps in research to guide best practices for bringing the implementation of cancer EBIs to scale in LMICs.

Abstract
Women living with HIV (WLWH) are at an increased risk of developing HPV-related high grade cervical dysplasia and cervical cancer. Prior World Health Organization (WHO) screening guidelines recommended starting screening at age 30. We assessed characteristics of women diagnosed with cervical cancer to further inform and refine screening guidelines. We prospectively enrolled women diagnosed with cervical cancer from January 2015 to March 2020 at two tertiary hospitals in Gaborone, Botswana. We performed chi-square and ANOVA analyses to evaluate the association between age upon diagnosis and HIV status, CD4 count, viral load, and other sociodemographic and clinical factors. Data were available for 1130 women who were diagnosed with cervical cancer and 69.3% were WLWH. The median age overall was 47.9 (IQR 41.2-59.1), 44.6 IQR: 39.8 - 50.9) among WLWH, and 61.2 (IQR 48.6-69.3) among women living without HIV. There were 1.3% of women aged <30 years old, 19.1% were 30-39 and 37.2% were 40-49. Overall, 20.4% (n = 231) of cancers were in women <40 years. Age of cervical cancer diagnosis is younger in countries with higher HIV prevalence, like Botswana. Approximately 20% of the patients presented with cancer at <40 years of age and would have likely benefited from screening 10 years prior to cancer diagnosis to provide an opportunity for detection and treatment of pre-invasive disease.

Abstract
Introduction Digital cervicography (DC) is a method of capturing images for analysis during visual inspection with acetic acid (VIA) for cervical cancer screening. Cervical cancer is the 3rd leading cause of female cancer in the world with approximately 90 % of deaths due to cervical cancer occurring in low and middle income countries (LMICs). The need for cost-effective and sustainable methods for screening is vital in these settings. This scoping review systematically synthesizes published data illustrating the use of DC in screening programs. We aim to understand how digital cervicography is used, implemented, and impacted on programs. Methods Search of eight online databases identified 53 studies published between 1993 and 2021. Inclusion of articles were English language, cervical cancer screening program located in an LMIC, and DC as an intervention. Results All studies were cross-sectional studies (n = 53), with variation in terminology, uses, and device methods. Devices were grouped as either smartphones (n = 14), commercially available digital cameras (n = 17), or other (EVA®, n = 4; Cerviscope, n = 12; custom device, n = 4; or not specified, n = 2). Nineteen studies found acceptability and feasibility for DC in their screening programs. Various programs using DC found benefits such as task sharing, healthcare worker training, patient education and using images for review from a remote specialist or mentor. Conclusion The use of DC in LMICs is beneficial for support of healthcare workers, enhances quality improvement and demonstrates overall acceptability in screening programs. Advancing technologies for human papillomavirus (HPV) testing and cytology are common methods for cervical cancer screening, although are limited in LMICs. This scoping review demonstrates the different methods, uses, and benefit of digital cervicography in cervical cancer screening programs.

Abstract
BACKGROUND An estimated 22 million Ethiopian women between the ages of 15 and 49 are affected by cervical cancer each year, with 7095 cases and 4732 fatalities. Cervical cancer screening is one of the prevention methods, although Ethiopia has a low coverage rate. Furthermore, data on the use of cervical cancer screening services in the country is scarce. Therefore, we aimed to assess cervical cancer screening practices and its associated factors among females of reproductive age in Durame, Southern Ethiopia. METHODS A community-based cross-sectional study was conducted using a multi-stage sampling technique among 460 females of reproductive age from March to April 2020. Data were collected using interviewer-administered questionnaires and analyzed using the Statistical Package for Social Science (SPSS) Version 20. Bivariable and multivariable logistic regressions were carried out to determine the association between independent and dependent variables. The adjusted odds ratio (AOR) with a 95% confidence interval (CI) and a P-value < 0.05 were used to declare the statistical association. RESULTS We found that cervical cancer screening practice in this study was 13.8% [95% CI:(10.4-17.2)]. Having a positive attitude [AOR = 5.2, 95% CI:(1.4, 20.0)], having a good knowledge [AOR = 5.4, 95% CI:(1.5,19.5)], being informed about cervical cancer by health professionals [AOR = 3.5, 95% CI:(1.3,9.8)], average monthly income greater than 3000 Ethiopian Birr (ETB) [AOR = 4.9, 95% CI:(1.1, 22)], and having a history of sexually transmitted infections [AOR = 4.2, 95% CI:(1.4,12.85)] were the factors associated with cervical cancer screening practice. CONCLUSIONS The practice of cervical cancer screening was found to be very low, being influenced by women's attitudes, knowledge, having health professionals as sources of information, monthly income, and history of sexually transmitted infections. Thus, it is necessary to increase awareness and knowledge about cervical cancer and improve attitudes toward cervical screening services to improve the uptake of the screening. Health professionals also have to play a pivotal role in properly addressing information about cervical cancer.

Abstract
BACKGROUND Cytology-based cervical cancer screening followed by confirmation and treatment of biopsy-proven high-grade squamous intraepithelial lesions (bHSIL) is difficult to implement in resource-constrained settings. We hypothesized that high-risk human papillomavirus (hrHPV) testing followed by immediate cryotherapy of women with hrHPV (HPV screen-and-treat) may improve outcomes. METHODS Randomized, open-label, phase 2, multinational clinical trial enrolling women with human immunodeficiency virus (HIV) age 18 or older with cervical hrHPV and having no cervical lesions or lesions appropriate for cryotherapy. Women were randomized to immediate cryotherapy (Arm A) or cytology-based screening (Arm B). For Arm A, cervical biopsies were obtained followed by cervical cryotherapy, and in Arm B, women with abnormal cytology underwent colposcopy followed by loop electroexcision procedure (LEEP) if bHSIL was detected. Women were followed through 30 months. The primary outcome was time to bHSIL detected from Month 6 through study completion. RESULTS In total, 288 women (145 in Arm A, 143 in Arm B) were randomized: median age 35 years, 84% on antiretroviral therapy, median CD4 501 cells/mm3. In Arm A, 39 (27%) of women had bHSIL at entry, and in Arm B, 88 (62%) had abnormal cytology, 22 (15%) were diagnosed with bHSIL, 12 (8%) underwent LEEP. In follow-up, 30 (21%) and 31 (22%) developed bHSIL; time to bHSIL was similar between arms (P=.94). The prevalence of hrHPV at Month 6 was similar between arms (61% and 70%, P=.13). CONCLUSIONS HPV test-and-treat was not associated with improved bHSIL outcomes as compared to cytology-based screening. More effective treatment options are required to improve outcomes from screen-and-treat programs. CLINICAL TRIALS REGISTRATION NCT01315363.

In order to improve visual assessment and identification of cervical intraepithelial neoplasia grade 2 and worse (CIN2+), providers may use visual aids such as digital cameras. OBJECTIVES To determine whether combined examination by naked-eye and digital VIA (D-VIA) and VILI (D-VILI) improves detection of CIN2+ as compared to the conventional evaluation. MATERIALS AND METHODS Women (30-49 years) living in Dschang (West Cameroon) were prospectively invited to a cervical cancer screening campaign. Primary HPV-based screening was followed by VIA/VILI and D-VIA/VILI if HPV-positive. Health care providers independently defined diagnosis (pathological or non-pathological) based on naked-eye VIA/VILI and D-VIA/VILI. Decision to treat was based on combined examination (VIA/VILI and D-VIA/VILI). Cervical biopsy and endocervical curettage were performed in all HPV-positive participants and considered as reference standard. Diagnostic performance of individual and combined naked-eye VIA/VILI and D-VIA/VILI was evaluated. A sample size of 1,500 women was calculated assuming a prevalence of 20% HPV positivity and 10% CIN2+ in HPV-positive women. RESULTS Due to the COVID-19 pandemic, the study had to terminate prematurely. A total of 1,081 women with a median age of 40 (IQR 35.5-45) were recruited. HPV positivity was 17.4% (n = 188) and 26 (14.4%) had CIN2+. Naked-eye VIA and D-VIA sensitivities were 80.8% (95% CI 60.6-93.4) and 92.0% (95% CI 74.0-99.0), and specificities were 31.2% (95% CI 24-39.1) and 31.6% (95% CI 24.4-39.6), respectively. The combination of both methods yielded a sensitivity of 92.3% (95% CI 74.9-99.1) and specificity of 23.2% (95% CI 16.8-30.7). A trend towards improved sensitivity was observed, but did not reach statistical significance. CONCLUSION Addition of D-VIA/VILI to conventional naked-eye examination may be associated with improved CIN2+ identification. Further studies including a larger sample size are needed to confirm these results.

The use of thermal ablation in diverse cervical cancer "screen-and-treat" service platforms in Zambia. Int J Gynaecol Obstet 2022; 157:85-89. [PMID: 34197624 DOI: 10.1002/ijgo.13808] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2021] [Revised: 06/17/2021] [Accepted: 06/30/2021] [Indexed: 11/07/2022]
Abstract
OBJECTIVE Thermal ablation (TA) was implemented in public sector cervical cancer prevention services in Zambia in 2012. Initially introduced as a treatment modality in primary healthcare clinics, it was later included in mobile outreach campaigns and clinical research trials. We report the feasibility, acceptability, safety, and provider uptake of TA in diverse clinical contexts. METHODS Screening services based on visual inspection with acetic acid were offered by trained nurses to non-pregnant women aged 25-59 years. Women with a type 1 transformation zone (TZ) were treated with same-visit TA. Those with a type 2 or 3 TZ, or suspicious for cancer, were managed with same-visit electrosurgical excision or punch biopsy, respectively. A provider survey was conducted. RESULTS Between 2012 and 2020, 2123 women were treated with TA: primary healthcare clinics, n = 746; mobile outreach clinics, n = 1127; research clinics, n = 250. Of the 996 women treated in primary healthcare and research clinics, 359 (48%) were HIV positive. Mild cramping during treatment was the most common adverse effect. No treatment interruptions occurred. No major complications were reported in the early (6 weeks) follow-up period. Providers expressed an overwhelming preference for TA over cryotherapy. CONCLUSION TA was feasible, safe, and acceptable in diverse clinical contexts. It was the preferred ablation method of providers when compared with cryotherapy.

Abstract
Abstract
Introduction Women living with human immunodeficiency virus (HIV) have an increased risk of persistent human papillomavirus infection (HPV) of developing cervical cancer precursors and are, therefore, considered at higher risk for cervical cancer. Despite the higher risk, screening for cervical cancer is extremely low among HIV-positive women in India.
Objectives Given the limited usefulness of cytology-based screening programs, the current study retrospectively evaluated the comparative performance of visual inspection with 5% acetic acid (VIA), conventional cytology, and human papillomavirus (HPV) testing among HIV-positive women attending the cancer screening clinic at the tertiary cancer center.
Materials and Methods Retrospective analysis of 291 HIV-positive women attending cervical cancer screening services in a tertiary cancer center in Mumbai was undertaken. All underwent simultaneous screening with VIA, Pap cytology, and HPV DNA testing, followed by diagnostic colposcopy and histopathology. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) to detect cervical intraepithelial neoplasia (CIN) 2/3 on histology were estimated.
Results The screen positivity rate for cervical cancer screening by VIA, high-risk HPV DNA, and Pap cytology was 35.7, 34.4, and 6.2% respectively. At the CIN2+ disease threshold, the sensitivity, specificity, PPV, and NPV estimates were 80.00% (59.30–93.17), 68.42% (62.46–73.96), 19.23% (15.46–23.67), 97.33% (94.30–98.77) for VIA; 80.00% (68.78–97.45), 70.68% (64.81–76.08), 22.00% (18.22–26.32), 98.43% (95.58–99.45) for HPV DNA; and 64.00% (42.52–82.03), 98.12% (95.67–99.39), 76.19% (56.13–88.89), 96.67% (94.50–98.00) for cytology (HSIL cutoff).
Conclusion The diagnostic performance of VIA and HPV DNA was comparable and better than cytology indicating that VIA as a cost-effective cervical cancer screening test can be incorporated within the services under sexually transmitted diseases /HIV testing and counseling centers within the country.

Cervical cancer screening and treatment, HIV infection, and age: Program implementation in seven regions of Namibia. PLoS One 2022; 17:e0263920. [PMID: 35171941 PMCID: PMC8849510 DOI: 10.1371/journal.pone.0263920] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Accepted: 01/31/2022] [Indexed: 11/19/2022] Open
Abstract
The aim of this study was to assess differences in cervical cancer screening and treatment outcomes by HIV status in a routine programmatic setting with a high generalized HIV prevalence. Women living with HIV (WLHIV) are at heightened risk of developing cervical cancer and the World Health Organization recommends all WLHIV who are sexually active be screened, regardless of age. In 2018, Namibia’s Ministry of Health and Social Services introduced a screen-and-treat approach using visual inspection with acetic acid (VIA) and ablative treatment with cryotherapy or thermocoagulation with a focus on screening HIV-positive women due to Namibia’s 11.5% prevalence of HIV in women aged 15–49. Using program data from October 2018 to March 2020 from seven of the country’s 14 regions, we calculated descriptive statistics and chi-square tests to test the statistical significance of differences in VIA-positivity, ineligibility for ablative treatment, treatment completion, and same day treatment completion by HIV status. Between October 2018 and March 2020, the program conducted 14,786 cervical cancer screenings. Among 8,150 women who received their first VIA screening, more WLHIV screened VIA-positive (17%) than HIV-negative women (15%). This difference was statistically significant (p = 0.02). Among 2,272 women who screened VIA-positive at any screening, 1,159 (82%) completed ablative treatment. This suggests ablative treatment is feasible and acceptable in resource-limited settings. WLHIV were also more likely to complete treatment than HIV-negative women (p<0.01). Differences in health seeking behavior of sub-populations as well as resource availability between service delivery points should be considered for further investigation. Going forward in order to strengthen program implementation and expand screening access and uptake further investigation is needed to determine cancer incidence by HIV status, age, and time since last screening to assess cases that are averted as well as potential rates of overtreatment.

Association of HIV status and treatment characteristics with VIA screening outcomes in Malawi: A retrospective analysis. PLoS One 2022; 17:e0262904.

Abstract
Background
Although evidence from high-resource settings indicates that women with HIV are at higher risk of acquiring high-risk HPV and developing cervical cancer, data from cervical cancer “screen and treat” programs using visual inspection with acetic acid (VIA) in lower-income countries have found mixed evidence about the association between HIV status and screening outcomes. Moreover, there is limited evidence regarding the effect of HIV-related characteristics (e.g., viral suppression, treatment factors) on screening outcomes in these high HIV burden settings.
Methods
This study aimed to evaluate the relationship between HIV status, HIV treatment, and viral suppression with cervical cancer screening outcomes. Data from a “screen and treat” program based at a large, free antiretroviral therapy (ART) clinic in Lilongwe, Malawi was retrospectively analyzed to determine rates of abnormal VIA results and suspected cancer, and coverage of same-day treatment. Multivariate logistic regression assessed associations between screening outcomes and HIV status, and among women living with HIV, viremia, ART treatment duration and BMI.
Results
Of 1405 women receiving first-time VIA screening between 2017–2019, 13 (0.9%) had suspected cancer and 68 (4.8%) had pre-cancerous lesions, of whom 50 (73.5%) received same-day lesion treatment. There was no significant association found between HIV status and screening outcomes. Among HIV+ women, abnormal VIA was positively associated with viral load ≥ 1000 copies/mL (aOR 3.02, 95% CI: 1.22, 7.49) and negatively associated with ART treatment duration (aOR 0.88 per additional year, 95% CI: 0.80, 0.98).
Conclusion
In this population of women living with HIV with high rates of ART coverage and viral suppression, HIV status was not significantly associated with abnormal cervical cancer screening results. We hypothesize that ART treatment and viral suppression may mitigate the elevated risk of cervical cancer for women living with HIV, and we encourage further study on this relationship in high HIV burden settings.

Comparative assessment of test characteristics of cervical cancer screening methods for implementation in low-resource settings. Prev Med 2022; 154:106883.

Abstract
Cervical cancer disproportionately affects low-resource settings. Papanicolaou, human papillomavirus (HPV), and visual inspection of cervix with acetic acid (VIA) testing, each with different characteristics, will reduce cervical cancer burden. We conducted a critical literature review using PubMed, Cochrane, WHO, and grey literature from 1994 to 2020. We examined efficacy, harms, and comparative effectiveness of screening methods by age, human immunodeficiency virus, provider characteristics, and assessed implementation challenges in low-resource settings. Comprehensive data on utility and efficacy of screening tests indicates that each screening has strengths and shortcomings but all confer acceptable performance. HPV and VIA appear more promising. Primary HPV test-and-treat, self-testing, and co-testing have been studied but data on triage plans, cost, support system, implementation and sustainability is unclear in low-resource settings. HPV testing could help target subgroups of older or higher risk women. VIA offers local capacity-building and scalability. Quality VIA technique after HPV testing is still required to guide post-screening treatments. VIA competencies decline gradually with current standard trainings. Stationary cervicography improves VIA quality but isn't scalable. Affordable smartphones eliminate this barrier, enhance training through mentorship, and advance continuing education and peer-to-peer training. Smartphone-based VIA facilitates cervical image storage for patient education, health promotion, record-keeping, follow-up care, remote expert support, and quality control to improve VIA reliability and reproducibility and reduce mis-diagnoses and burden to health systems. Rather than ranking screening methods using test characteristics alone in study or higher-resource settings, we advocate for scalable strategies that maximize reliability and access and reduce cost and human resources.

Abstract
Despite being highly preventable, cervical cancer is the fourth most common cancer and cause of cancer death in women globally. In low-income countries, cervical cancer is often the leading cause of cancer-related morbidity and mortality. Women living with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome are at a particularly high risk of cervical cancer because of an impaired immune response to human papillomavirus, the obligate cause of virtually all cervical cancers. Globally, approximately 1 in 20 cervical cancers is attributable to HIV; in sub-Saharan Africa, approximately 1 in 5 cervical cancers is due to HIV. Here, the authors provide a critical appraisal of the evidence to date on the impact of HIV disease on cervical cancer risk, describe key methodologic issues, and frame the key outstanding research questions, especially as they apply to ongoing global efforts for prevention and control of cervical cancer. Expanded efforts to integrate HIV care with cervical cancer prevention and control, and vice versa, could assist the global effort to eliminate cervical cancer as a public health problem.

Abstract
BACKGROUND Cervical cancer is the leading cause of cancer deaths among women in developing countries. Since cervical cancer is a preventable disease, screening is an important control and prevention strategy, recommended by the World Health Organization (WHO) for all women aged 30 years and older, and even earlier for some high-risk women. Therefore the aim of this study was to assess the uptake of cervical cancer screening among age-eligible women in Ethiopia. METHOD Review identification was performed through the search of online databases PubMed, Google Scholar, HINARI, EMBASE, Science Direct, Cochrane library, African Journals, and other gray and online repository accessed studies were searched using different search engines. For critical appraisal of studies, Newcastle-Ottawa Quality Assessment Scale (NOS) was used. The analysis was conducted by using STATA 11 software. To test the heterogeneity of studies, the Cochran Q test and I2 test statistics were used. To detect publication bias of the studies, the funnel plot and Egger's test were used. The pooled prevalence of cervical cancer screening and the odds ratio (OR) with a 95% confidence interval were presented using forest plots. RESULT Twenty-four studies with a total of 14,582 age-eligible women were included in this meta-analysis. The pooled national level of cervical cancer screening among age-eligible women in Ethiopia was 13.46% (95%CI:11.06,15.86). Knowledge on cervical cancer and screening (OR = 4.01,95%CI:2.76,5.92), history of multiple sexual partners (OR = 5.01, 95%CI:2.61,9.61), women's age (OR = 4.58, 95%CI:2.81,7.46), history of sexually transmitted disease (OR = 4.83,95%CI:3.02,7.73), Perceived susceptibility to cervical cancer (OR = 3.59, 95%CI:1.99,6.48), getting advice from health care providers (OR = 4.58, 95%CI:3.26, 6.43), women's educational level (OR = 6.68,95%CI:4.61,9.68), women's attitude towards cervical cancer and screening (OR = 3.42, 95%CI:2.88,4.06) were the determinant factors of cervical cancer screening uptake among age-eligible women in Ethiopia. CONCLUSION The pooled prevalence of cervical cancer screening was remarkably low among age-eligible women in Ethiopia. Thus, to increase the uptake of cervical cancer screening among age-eligible women regularly, it is better to create awareness programs for early detection and treatment of cervical cancer, and educational interventions that teach the step-by-step practice of cervical screening to increase women's attitude for screening. Additionally, it is better to inform every woman is susceptible to cervical cancer, especially after starting sexual intercourse, and screening remains fundamental in the fight against cervical cancer before becoming invasive. Moreover, counseling and improving the confidence of women by health care providers to undergo screening is recommended.

Abstract
BACKGROUND Cervical cancer is among the most common preventable cancers with the highest morbidity and mortality. The World Health Organization (WHO) recommends visual inspection of the cervix with acetic acid (VIA) as cervical cancer screening strategy in resource-poor settings. However, there are barriers to the sustainability of VIA programs including declining providers' VIA competence without mentorship and quality assurances and challenges of integration into primary healthcare. This study seeks to evaluate the impact of smartphone-based strategies in improving reliability, reproducibility, and quality of VIA in humanitarian settings. METHODS AND FINDINGS We implemented smartphone-based VIA that included standard VIA training, adapted refresher, and 6-month mHealth mentorship, sequentially, in the rural Shiselweni region of Eswatini. A remote expert reviewer provided diagnostic and management feedback on patients' cervical images, which were reviewed weekly by nurses. Program's outcomes, VIA image agreement rates, and Kappa statistic were compared before, during, and after training. From September 1, 2016 to December 31, 2018, 4,247 patients underwent screening; 247 were reviewed weekly by a VIA diagnostic expert. Of the 247, 128 (49%) were HIV-positive; mean age was 30.80 years (standard deviation [SD]: 7.74 years). Initial VIA positivity of 16% (436/2,637) after standard training gradually increased to 25.1% (293/1,168), dropped to an average of 9.7% (143/1,469) with a lowest of 7% (20/284) after refresher in 2017 (p = 0.001), increased again to an average of 9.6% (240/2,488) with a highest of 17% (17/100) before the start of mentorship, and dropped to an average of 8.3% (134/1,610) in 2018 with an average of 6.3% (37/591) after the start of mentorship (p = 0.019). Overall, 88% were eligible for and 68% received cryotherapy the same day: 10 cases were clinically suspicious for cancer; however, only 5 of those cases were confirmed using punch biopsy. Agreement rates with the expert reviewer for positive and negative cases were 100% (95% confidence interval [CI]: 79.4% to 100%) and 95.7% (95% CI: 92.2% to 97.9%), respectively, with negative predictive value (NPV) (100%), positive predictive value (PPV) (63.5%), and area under the curve of receiver operating characteristics (AUC ROC) (0.978). Kappa statistic was 0.74 (95% CI; 0.58 to 0.89); 0.64 and 0.79 at 3 and 6 months, respectively. In logistic regression, HIV and age were associated with VIA positivity (adjusted Odds Ratio [aOR]: 3.53, 95% CI: 1.10 to 11.29; p = 0.033 and aOR: 1.06, 95% CI: 1.0004 to 1.13; p = 0.048, respectively). We were unable to incorporate a control arm due to logistical constraints in routine humanitarian settings. CONCLUSIONS Our findings suggest that smartphone mentorship provided experiential learning to improve nurses' competencies and VIA reliability and reproducibility, reduced false positive, and introduced peer-to-peer education and quality control services. Local collaboration; extending services to remote populations; decreasing unnecessary burden to screened women, providers, and tertiary centers; and capacity building through low-tech high-yield screening are promising strategies for scale-up of VIA programs.

Abstract
Background Although an opportunistic approach of cervical cancer screening strategy had been implemented in Ethiopia, utilization of screening services among women is still low, accounted < 1%. We hypothesize that commercial sex women in Ethiopia faced a number of obstacles in order to access screening services. Identifying the predictors influencing utilizations of the screening services is an essential effort to tailor screening program towards increasing the utilization. Methods An unmatched case-control study was implemented with a total sample size of 230 (46 cases and 184 controls). The study was conducted among commercial sex workers who attended confidential clinic opened for sex workers. Simple random sampling was employed. After the data were checked for completeness, consistency and accuracy, it was entered in to Epi nfo version 7 then exported to SPSS for further statistical analysis. Descriptive statistics were used to describe the profile of study participants. Logistic regression was employed to identify the predictors of cervical cancer screening uptake. P < 0.05 was computed to determine the level of statistical significance. Results Cervical cancer screening utilization was associated with providers’ recommendation (AOR = 6.8; 95% CI: 2.3, 9.7), history of sexually transmitted infection (AOR = 6.9; 95% CI: 1.29, 7.2), frequency of facility visit (AOR = 4.8; 95% CI: 1.97, 11.8) and history of vaginal examination (AOR = 0.21; 95% CI: 0.1, 0.68). Conclusions The level of cervical cancer screening service utilization was higher among women with history of STI, frequency of facility visit and providers’ recommendation. The level of cervical cancer screening service utilization was lower in women with previous vaginal examination.

Abstract
AIM Considering the burden of cervical cancer in India, innovative approaches are needed to improve coverage of cervical cancer screening. METHODS From May 2014 to January 2017, we implemented a project in 10 cities in Uttar Pradesh, India using World Health Organization-recommended 'screen and treat' approach for cervical cancer prevention. We involved private practitioners (obstetricians and gynecologists and general practitioners) in these cities to provide affordable cervical cancer screening to women mobilized by our community health workers. A pilot phase was implemented in three cities during May 2014 and December 2015 and the project was scaled-up to additional seven cities between January 2016 and January 2017. RESULTS A total of 100 836 women aged between 30 and 60 years were screened with visual inspection with acetic acid (VIA) of which 5477 (5.4%, 95% confidence interval (CI) 5.29, 5.57) were VIA positive. Treatment with cryotherapy was given to 3735 (68.2%, 95% CI 66.96, 69.43) women. In the three cities that piloted the program, VIA positivity rates significantly declined from 6.6% (95% CI 6.31, 6.84) to 4.0% (95% CI 3.82, 4.24) during the scale-up phase (P < 0.0001) and the rates of cryotherapy significantly increased from 66.8% (95% CI 64.78, 68.77) to 76.7% (95% CI 74.42, 78.96) (P < 0.0001). CONCLUSION We observed a significant decline in the VIA positivity rates during the scale-up phase in the three cities that participated in the pilot phase. We have reported successful engagement of private practitioners to provide affordable cervical cancer screening and it is possible to replicate it in other states in India as well.

HIV status, age at cervical Cancer screening and cervical cytology outcomes in an opportunistic screening setting in Nigeria: a 10-year Cross sectional data analysis. Infect Agent Cancer 2019; 14:43. [PMID: 31798680 PMCID: PMC6884842 DOI: 10.1186/s13027-019-0263-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2019] [Accepted: 11/20/2019] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Invasive cervical cancer (ICC) is more prevalent in HIV infected women and occurs at younger median age than in HIV negative women. Organized cervical cancer screening (CCS) is presently lacking in Nigeria, and the age at CCS is not known in this population. We sought to examine the age at CCS, the cytology outcomes and whether outcomes differ by HIV infection status in an opportunistic screening setting. METHODS Cross-sectional analysis of data on a sample of women who had received a CCS in an opportunistic screening service in Jos, Nigeria over a 10-year time period (2006-2016). We used logistic regression models to estimate the independent effect of patient-reported HIV and age at CCS and odds ratios for abnormal cytology outcomes adjusting for other covariates. We also assessed the correlation between median age at CCS and severity of abnormal cervical cytology outcomes. Statistical analyses were done on STATA version 14, College Station, Texas, USA. RESULTS In a sample of 14,088, the median age at CCS was 37 years (IQR; 30-45). For HIV infected women vs. uninfected women, CCS occurred at earlier ages (35.0 ± 7.4 vs 38.2 ± 10.2 years, p < 0.001). All women, regardless of HIV status, who completed at least 7 or more years of education were 1.27 to 3.51 times more likely to have CCS before age 35 than women with less education. The predictors of an abnormal cervical cytology outcome at CCS were: age at CCS ≥ 35 (aOR = 3.57; 95% CI: 2.74, 4.64), multiparity ≥5 (aOR = 1.27; 95% CI: 1.03, 1.56), and provider-referral (aOR = 1.34; 95% CI: 1.09, 1.64). Irrespective of reported HIV status, we found a positive correlation between median age at CCS and severity of cytology outcome. DISCUSSION The age at CCS in women who have utilized cervical cancer screening in the study population is relatively late compared to the recommended age by most guidelines from developed settings. Late age at CCS correlates positively with severity of abnormal cytology outcome irrespective of HIV status. More educated women are more likely to have CCS at early age and less likely to have underlying abnormal cytology outcomes.

Abstract
OBJECTIVES Cervical cancer is among the leading cancer related causes of morbidity and mortality of women in the world. Ethiopia is among the highest risk countries with age adjusted incidence of cervical cancer 35.9 per 100,000 women or 7619 new cases and 6081 deaths of cervical cancer each year. The aim of this study was to examine correlates of cervical cancer screening uptake among female under graduate students of Aksum University, College of Health Sciences. Data was collected using self-administered structured questionnaire. Variables that were statistically significantly associated with the outcome in bivariate analyses were considered in a logistic multivariate regression analysis. RESULT Only 17.2% of students were screened for cervical cancer in their lifetime. Both in bivariate and multivariate analysis, sexual experience (AOR = 38.85; 95% CI [8.907, 169.51]), marital status (AOR = 3.481; 95% CI [1.167, 10.380]), Ppace of birth (AOR = 3.359; 95% CI [1.559, 7.235]), and student's year of study (AOR = 0.005; 95% CI [0.001, 0.031]) were the only correlates of cervical cancer screening uptake among female students. Therefore, the overall cervical cancer screening uptake was low and further study should be done other correlates.

Abstract
OBJECTIVE To explore acceptability and feasibility of smartphone-based training of low-level to mid-level health professionals in cervical cancer screening using visual inspection with acetic acid (VIA)/cervicography. DESIGN In 2015, we applied a qualitative descriptive approach and conducted semi-structured interviews and focus groups to assess the perceptions and experiences of community health nurses (CHNs) (n=15) who performed smartphone-based VIA, patients undergoing VIA/cryotherapy (n=21) and nurse supervisor and the expert reviewer (n=2). SETTING Community health centres (CHCs) in Accra, Ghana. RESULTS The 3-month smartphone-based training and mentorship was perceived as an important and essential complementary process to further develop diagnostic and management competencies. Cervical imaging provided peer-to-peer learning opportunities, and helped better communicate the procedure to and gain trust of patients, provide targeted education, improve adherence and implement quality control. None of the patients had prior screening; they overwhelmingly accepted smartphone-based VIA, expressing no significant privacy issues. Neither group cited significant barriers to performing or receiving VIA at CHCs, the incorporation of smartphone imaging and mentorship via text messaging. CHNs were able to leverage their existing community relationships to address a lack of knowledge and misperceptions. Patients largely expressed decision-making autonomy regarding screening. Negative views and stigma were present but not significantly limiting, and the majority felt that screening strategies were acceptable and effective. CONCLUSIONS Our findings suggest the overall acceptability of this approach from the perspectives of all stakeholders with important promises for smartphone-based VIA implementation. Larger-scale health services research could further provide important lessons for addressing this burden in low-income and middle-income countries.

Abstract
OBJECTIVES Cervical cancer screening by visual inspection with acetic acid (VIA) is a widely used alternative to cytology in developing countries. This study aimed to evaluate risk factors associated with a positive VIA test and with cervical high-grade lesions on cytology. METHODS We conducted a large cross-sectional study among 3339 women from urban and rural Tanzania. Study participants were interviewed about socio-demographic, reproductive and lifestyle factors. Blood samples were tested for HIV, and a gynaecological examination was performed. Human papillomavirus (HPV) status was determined by Hybrid Capture 2, and HPV genotyping was done using the LiPA Extra test. We used multivariable logistic regression to estimate adjusted odds ratios (ORs) and confidence intervals (CIs). RESULTS The strongest risk factors for VIA positivity were positivity to HIV (OR = 3.48; 95% CI: 2.34-5.17) or to high-risk HPV (HrHPV) (OR = 1.97; 95% CI: 1.37-2.85). HrHPV was by far the strongest predictor of high-grade cytology (OR = 110.1; 95% CI: 50.4-240.4), while there was no significant association with HIV in the multivariable analysis (OR = 1.27; 95% CI: 0.78-2.08). After adjustment for HrHPV, HIV and age, the risk of high-grade cytology also increased with increasing age, number of births and low body mass index (BMI), while high BMI decreased the risk of VIA positivity. CONCLUSIONS Infection with HrHPV is a major risk factor for high-grade cytology, while VIA positivity is associated with HIV and to a lesser extent with HrHPV.

Abstract
BACKGROUND Cervical cancer screening (CCS) is an important health service intervention for prevention of morbidity and mortality from invasive cervical cancer. The role of provider recommendation and referral is critical in utilization of this services particularly in settings where screening is largely opportunistic. We sought to understand how patient-reported human immunodeficiency virus (HIV) infection status is associated with provider referral in an opportunistic screening setting. METHODS We performed a cross-sectional analysis of data on a sample of women who had received a CCS at the "Operation Stop" cervical cancer (OSCC) screening service in Jos, Nigeria over a 10-year time period (2006-2016). We used the de-identified records of women who had their first CCS to analyze the association between patient-reported HIV and likelihood of provider-referral at first CCS. We performed descriptive statistics with relevant test of association using Student t-test (t-test) for continuous variables and Pearson chi square or Fisher exact test where applicable for categorical variables. We also used a bivariable and multivariable logistic regression models to estimate the independent association of patient-reported HIV on provider referral. All statistical tests were performed using STATA version 14.1, College Station, Texas, USA. Level of statistical significance was set at 0.05. RESULTS During the 10-year period, 14,088 women had their first CCS. The reported HIV prevalence in the population was 5.0%; 95% CI: 4.6, 5.4 (703/14,088). The median age of women who were screened was 37 years (IQR; 30-45). Women who were HIV infected received more referrals from providers compared to women who were HIV uninfected (68.7% versus 49.2%), p-value < 0.001. Similarly, we found an independent effect of patient-reported HIV infection on the likelihood for provider-referral in the screened sample (aOR = 2.35; 95% CI: 1.95, 2.82). CONCLUSION Our analysis supports the design of health systems that facilitates providers' engagement and provision of necessary counseling for CCS in the course of routine clinical care. The practice of offering recommendation and referrals for CCS to women at high risk of cervical cancer, such as HIV infected women should be supported.

Abstract
BACKGROUND Zambia has one of the highest cervical cancer incidence and mortality rates in the world. Cervical cancer screening leads to reduction in the incidence of invasive disease. The objectives of the study were to determine the level of acceptance of cervical cancer screening and its correlates among women of a peri-urban high-density residential area in Ndola, Zambia. METHODS A cross sectional study was conducted. With a population size of 12,000 women in reproductive age and using an expected frequency of 50 + 5% and at 95% confidence interval, the required sample size was 372. A stratified sampling method was used to select participants. Independent factors that were associated with the outcome were established using multi-variate logistic regression. Adjusted odds ratios and their 95% confidence intervals are reported. RESULTS In total, 355 out of 372 questionnaires were administered, achieving a response rate of 95.4%. Out of 355 participants, 9 (2.5%) had ever been screened for cervical cancer. In bivariate analyses, factors associated with screened were knowledge of body part affected, screening as a prevention tool, whether cervical cancer was curable in its early stages or not, awareness of cervical cancer screening, knowledge on frequency of screening and cervical cancer screening causing harm. However, in multivariate analysis, participants who knew that cervical cancer screening prevented cervical cancer were 3.58 (95% CI [1.49, 8.64]) times more likely to have been screened than those who did not have the knowledge. Participants who knew that cervical cancer is curable were 2.76 (95% CI [1.92, 8.31]) times more likely to have been screened than those who did not have the knowledge. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS The uptake of screening was low. Interventions should be designed to increase uptake of screening for cervical cancer by considering factors that have been identified in the current study that are independently associated with cervical cancer screening among this population.

Abstract
Integration of services for patients with more than one diagnosed condition has intuitive appeal but it has been argued that the empirical evidence to support it is limited. We report the findings of a systematic review that sought to identify health system factors, extrinsic to the integration process, which either facilitated or hindered the integration of services for two common disorders, HIV and chronic non-communicable diseases. Findings were initially extracted and organized around a health system framework, followed by a thematic cross-cutting analysis and validation steps. Of the 150 articles included, 67% (n = 102) were from high-income countries. The articles explored integration with services for one or several chronic disorders, the most studied being alcohol or substance use disorders (47.7%), and mental health issues (29.5%). Four cross-cutting themes related to the health system were identified. The first and most common theme was the requirement for effective collaboration and coordination: formal and informal productive relationships throughout the system between providers and within teams, and between staff and patients. The second was the need for adequate and appropriately skilled and incentivized health workers-with the right expertise, training and operational support for the programme. The third was the need for supportive institutional structures and dedicated resources. The fourth was leadership in terms of political will, effective managerial oversight and organizational culture, indicating that actual implementation is as important as programme design. A fifth theme, outside the health system, but underpinning all aspects of the system operation, was that placing the patient at the centre of service delivery and responding holistically to their diverse needs. This was an important facilitator of integration. These findings confirm that integration processes in service delivery depend substantially for their success on characteristics of the health systems in which they are embedded.

Abstract
Cervical cancer is a leading cause of mortality in Sub-Saharan Africa-in large part because of inadequate coverage of screening and preventive treatment services. A number of programs have begun integrating cervical cancer prevention services into existing family planning or HIV/AIDS service delivery platforms, to rapidly expand "screen and treat" programs and mitigate cervical cancer burden. Drawing upon a review of literature and our experiences, we consider benefits and challenges associated with such programs in Sub-Saharan Africa. We then outline steps that can optimize uptake and sustainability of integrated sexual and reproductive health services. These include increasing coordination among implementing organizations for efficient use of resources; task shifting for services that can be provided by nonphysicians; mobilizing communities via trusted frontline health workers; strengthening management information systems to allow for monitoring of multiple services; and prioritizing an operational research agenda to provide further evidence on the cost-effectiveness and benefits of integrated service delivery.

Abstract
BACKGROUND Cervical cancer is a major public health problem. Even though readily preventable, it is the fourth leading cause of death in women globally. Women living with HIV are at increased risk of invasive cervical cancer, highlighting the need for access to screening and treatment for this population. Integration of services has been proposed as an effective way of improving access to cervical cancer screening especially in areas of high HIV prevalence as well as lower resourced settings. This paper presents the results of a systematic review of programs integrating cervical cancer and HIV services globally, including feasibility, acceptability, clinical outcomes and facilitators for service delivery. METHODS This is part of a larger systematic review on integration of services for HIV and non-communicable diseases. To be considered for inclusion studies had to report on programs to integrate cervical cancer and HIV services at the level of service delivery. We searched multiple databases including Global Health, Medline and Embase from inception until December 2015. Articles were screened independently by two reviewers for inclusion and data were extracted and assessed for risk of bias. MAIN RESULTS 11,057 records were identified initially. 7,616 articles were screened by title and abstract for inclusion. A total of 21 papers reporting interventions integrating cervical cancer care and HIV services met the criteria for inclusion. All but one study described integration of cervical cancer screening services into existing HIV services. Most programs also offered treatment of minor lesions, a 'screen-and-treat' approach, with some also offering treatment of larger lesions within the same visit. Three distinct models of integration were identified. One model described integration within the same clinic through training of existing staff. Another model described integration through co-location of services, with the third model describing programs of integration through complex coordination across the care pathway. The studies suggested that integration of cervical cancer services with HIV services using all models was feasible and acceptable to patients. However, several barriers were reported, including high loss to follow up for further treatment, limited human-resources, and logistical and chain management support. Using visual screening methods can facilitate screening and treatment of minor to larger lesions in a single 'screen-and-treat' visit. Complex integration in a single-visit was shown to reduce loss to follow up. The use of existing health infrastructure and funding together with comprehensive staff training and supervision, community engagement and digital technology were some of the many other facilitators for integration reported across models. CONCLUSIONS This review shows that integration of cervical cancer screening and treatment with HIV services using different models of service delivery is feasible as well as acceptable to women living with HIV. However, the descriptive nature of most papers and lack of data on the effect on long-term outcomes for HIV or cervical cancer limits the inference on the effectiveness of the integrated programs. There is a need for strengthening of health systems across the care continuum and for high quality studies evaluating the effect of integration on HIV as well as on cervical cancer outcomes.

Abstract
Objective This study evaluated the potential cost-effectiveness of cervical cancer screening in HIV treatment clinics in Nairobi, Kenya. Methods A Markov model was used to project health outcomes and costs of cervical cancer screening and cryotherapy at an HIV clinic in Kenya using cryotherapy without screening, visual inspection with acetic acid (VIA), Papanicolaou smear (Pap), and testing for human papillomavirus (HPV). Direct and indirect medical and non-medical costs were examined from societal and clinic perspectives. Results Costs of cryotherapy, VIA, Pap, and HPV for women with CD4 200–500 cells/mL were $99, $196, $219, and $223 from a societal perspective and $19, $94, $124, and $113 from a clinic perspective, with 17.3, 17.1, 17.1, and 17.1 years of life expectancy, respectively. Women at higher CD4 counts (>500 cells/mL) given cryotherapy VIA, Pap, and HPV resulted in better life expectancies (19.9+ years) and lower cost (societal: $49, $99, $115, and $102; clinic: $13, $51, $71, and $56). VIA was less expensive than HPV unless HPV screening could be reduced to a single visit. Conclusions Preventative cryotherapy was the least expensive strategy and resulted in highest projected life expectancy, while VIA was most cost-effective unless HPV could be reduced to a single visit.

Implementing a Fee-for-Service Cervical Cancer Screening and Treatment Program in Cameroon: Challenges and Opportunities. Oncologist 2017; 22:850-859.

Abstract
BACKGROUND Cervical cancer screening is one of the most effective cancer prevention strategies, but most women in Africa have never been screened. In 2007, the Cameroon Baptist Convention Health Services, a large faith-based health care system in Cameroon, initiated the Women's Health Program (WHP) to address this disparity. The WHP provides fee-for-service cervical cancer screening using visual inspection with acetic acid enhanced by digital cervicography (VIA-DC), prioritizing care for women living with HIV/AIDS. They also provide clinical breast examination, family planning (FP) services, and treatment for reproductive tract infection (RTI). Here, we document the strengths and challenges of the WHP screening program and the unique aspects of the WHP model, including a fee-for-service payment system and the provision of other women's health services. METHODS We retrospectively reviewed WHP medical records from women who presented for cervical cancer screening from 2007-2014. RESULTS In 8 years, WHP nurses screened 44,979 women for cervical cancer. The number of women screened increased nearly every year. The WHP is sustained primarily on fees-for-service, with external funding totaling about $20,000 annually. In 2014, of 12,191 women screened for cervical cancer, 99% received clinical breast exams, 19% received FP services, and 4.7% received treatment for RTIs. We document successes, challenges, solutions implemented, and recommendations for optimizing this screening model. CONCLUSION The WHP's experience using a fee-for-service model for cervical cancer screening demonstrates that in Cameroon VIA-DC is acceptable, feasible, and scalable and can be nearly self-sustaining. Integrating other women's health services enabled women to address additional health care needs. IMPLICATION FOR PRACTICE The Cameroon Baptist Convention Health Services Women's Health Program successfully implemented a nurse-led, fee-for-service cervical cancer screening program using visual inspection with acetic acid-enhanced by digital cervicography in the setting of a large faith-based health care system in Cameroon. It is potentially replicable in many African countries, where faith-based organizations provide a large portion of health care. The cost-recovery model and concept of offering multiple services in a single clinic rather than stand-alone "silo" cervical cancer screening could provide a model for other low-and-middle-income countries planning to roll out a new, or make an existing, cervical cancer screening services accessible, comprehensive, and sustainable.

Abstract
OBJECTIVES We sought to determine the clinical performance of visual inspection with acetic acid (VIA), digital cervicography (DC), Xpert human papillomavirus (HPV), and OncoE6 for cervical cancer screening in an HIV-infected population. MATERIALS AND METHODS HIV-infected women 18 years or older were included in this cross-sectional validation study conducted in Lusaka, Zambia. The screening tests were compared against a histological gold standard. We calculated sensitivity, specificity, positive and negative predictive values, positive and negative likelihood ratios, and odds ratios using cervical intraepithelial neoplasia grade 2 or worse (CIN 2+) and grade 3 or worse (CIN 3+) thresholds. RESULTS Between January and June 2015, a total of 200 women were enrolled. Fifteen percent were screen positive by VIA, 20% by DC, 47% by Xpert HPV, and 6% by OncoE6. Using a CIN 2+ threshold, the sensitivity and specificity of VIA were 48% (95% CI = 30%-67%) and 92% (95% CI = 86%-95%), respectively. Similarly, the sensitivity and specificity of DC were 59% (95% CI = 41%-76%) and 88% (95% CI = 82%-93%), respectively. The sensitivity and specificity of Xpert HPV were 88% (95% CI = 71%-97%) and 60% (95% CI = 52%-68%), respectively. Finally, the sensitivity and specificity of OncoE6 were 31% (95% CI = 16%-50%) and 99% (95% CI = 97%-100%), respectively. CONCLUSIONS VIA and DC displayed moderate sensitivity and high specificity. Xpert HPV performed equivalently to currently approved HPV DNA tests, with high sensitivity and moderate specificity. OncoE6 displayed excellent specificity but low sensitivity. These results confirm an important role for VIA, DC, and Xpert HPV in screen-and-treat cervical cancer prevention in low- and middle-income countries, such as Zambia.

Abstract
Cervical cancer (CC) is a leading cause of cancer-related death and a major public health issue in sub-Saharan Africa. This heavy burden parallels that of the human immunodeficiency virus (HIV) infection, which increases the risk of developing CC. Despite the progressive reduction of HIV prevalence in the past decade, the CC incidence and mortality rates in sub-Saharan Africa remain high. The heterogeneity of the distribution of the two diseases in the African continent, together with the different availability of human and material resources, stands in the way of finding an appropriate screening strategy. The lack of high-quality evidence on the prevention of CC for HIV-positive women, which is necessary for the implementation of efficient screening and treatment strategies, results in the absence of a clearly defined program, which is responsible for the low screening uptake and high mortality rates in sub-Saharan Africa. By taking advantage of the HIV-positive women's frequent access to health facilities, one way to increase the CC screening coverage rates would be by providing integrated HIV and screening services within the same infrastructure. With the increasing availability of cost-effective methods, screening is becoming more and more available to women who have limited access to health care. Moreover, the introduction of point-of-care technologies for human papillomavirus testing and the subsequent implementation of screen-and-treat strategies, by reducing the number of clinical appointments and, in the long term, the loss to follow-up rates, open up new opportunities for all women, regardless of their HIV status. The purpose of this review is to provide an insight into the different screening practices for CC in order to help define one that is adapted to the resources and necessities of HIV-positive women living in middle-to-low income countries.

Abstract
OBJECTIVE Approximately 85% of cervical cancer cases and deaths occur in resource-constrained countries where best practices for prevention, particularly for women with HIV infection, still need to be developed. The aim of this study was to assess cervical cancer prevention capacity in select HIV clinics located in resource-constrained countries. MATERIALS AND METHODS A cross-sectional survey of sub-Saharan African sites of 4 National Institutes of Health-funded HIV/AIDS networks was conducted. Sites were surveyed on the availability of cervical cancer screening and treatment among women with HIV infection and without HIV infection. Descriptive statistics and χ or Fisher exact test were used as appropriate. RESULTS Fifty-one (65%) of 78 sites responded. Access to cervical cancer screening was reported by 49 sites (96%). Of these sites, 39 (80%) performed screening on-site. Central African sites were less likely to have screening on-site (p = .02) versus other areas. Visual inspection with acetic acid and Pap testing were the most commonly available on-site screening methods at 31 (79%) and 26 (67%) sites, respectively. High-risk HPV testing was available at 29% of sites with visual inspection with acetic acid and 50% of sites with Pap testing. Cryotherapy and radical hysterectomy were the most commonly available on-site treatment methods for premalignant and malignant lesions at 29 (74%) and 18 (46%) sites, respectively. CONCLUSIONS Despite limited resources, most sites surveyed had the capacity to perform cervical cancer screening and treatment. The existing infrastructure of HIV clinical and research sites may provide the ideal framework for scale-up of cervical cancer prevention in resource-constrained countries with a high burden of cervical dysplasia.

Abstract
BACKGROUND Malawi has the highest cervical cancer incidence and mortality in the world with age-standardized rate (ASR) of 75.9 and 49.8 per 100,000 population respectively. In response, Ministry of Health established a cervical cancer screening programme using visual inspection with acetic acid (VIA) and treatment of precancerous lesions with cryotherapy. This paper highlights the roll out, integration with family planning services and HIV ART Programme, uptake and challenges of VIA and Cryotherapy programme. METHODS We analyzed program data, supportive supervision, quarterly and annual reports from the National Cervical Cancer Control Program. We evaluated the uptake and challenges of screening services by age, HIV serostatus and trends over a five year period (2011-2015). RESULTS Between 2011 and 2015, number of cervical cancer screening sites, number of women screened and coverage per annum increased from 75 to 130, 15,331 to 49,301 and 9.3 % to 26.5 % respectively. In this five year period, a total of 145,015 women were screened. Of these, 7,349 (5.1 %) and 6,289 (4.3 %) were VIA positive and suspect cancer respectively. Overall 13,638 (9.4 %) were detected to be VIA positive or had suspect cancer. Of the 48,588 women with known age screened in 2015; 13,642 (28.1 %), 27,275 (56.1 %) and 7,671 (15.8 %) were aged 29 or less, 30-45, 46 years or more. Among 39,101 women with data on HIV serostatus; 21,546 (55.1 %) were HIV negative, 6,209 (15.9 %) were HIV positive and 11, 346 (29.0 %) status was unknown. VIA positivity rate and prevalence of suspect cancer were significantly higher in HIV positive than HIV negative women (8.8 % vs 5.0 %, 6.4 % vs 3.0 %); in women aged 30-45 years than women aged 29 years or less (5.6 % vs 2.3 %, 2.6 % vs 1.2 %) respectively, all p <0.05). The main challenge of the programme was failure to treat VIA positive women eligible for cryotherapy. Over the five year period, the programme only treated 1,001 (43.3 %) out of 2,311 eligible women and only 266 (31.8 %) of the 836 women with large lesion or suspect cancer who were referred, received the health care at the referral centre. The reasons for failure to provide cryotherapy treatment were stock out of gas, faulty/broken cryotherapy machine (usually connectors or probes) or no cryotherapy machine at all in the whole district. For women with large lesion or suspect cancer; lack of loop electrosurgical excision procedure (LEEP) machine or inadequate gynaecologists at the referral centre, were the major reasons. Cancer radiotherapy services were not available in Malawi. CONCLUSIONS This study provided data on VIA positivity rate, prevalence of suspect cancer, failure rate of cryotherapy and challenges in the provision of cryotherapy and LEEP treatment in Malawi. These data could be used as baseline for monitoring and evaluation of Human Papillomavirus (HPV) vaccination programme which the country introduced in 2013, the linkage of cervical cancer screening and women on HIV ART and the long term effect of ART, voluntary male medical circumcision on the prevalence and incidence of cervical cancer.

Vaginal Self-Sampling for Human Papillomavirus Infection as a Primary Cervical Cancer Screening Tool in a Haitian Population. Sex Transm Dis 2016; 42:655-9. [PMID: 26462192 DOI: 10.1097/olq.0000000000000345] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/05/2023]
Abstract
BACKGROUND Human papillomavirus (HPV) testing as primary cervical cancer screening has not been studied in Caribbean women. We tested vaginal self-collection versus physician cervical sampling in a population of Haitian women. METHODS Participants were screened for high-risk HPV with self-performed vaginal and clinician-collected cervical samples using Hybrid Capture 2 assays (Qiagen, Gaithersburg, MD). Women positive by either method then underwent colposcopy with biopsy of all visible lesions. Sensitivity and positive predictive value were calculated for each sample method compared with biopsy results, with κ statistics performed for agreement. McNemar tests were performed for differences in sensitivity at ≥cervical intraepithelial neoplasia (CIN)-I and ≥CIN-II. RESULTS Of 1845 women screened, 446 (24.3%) were HPV positive by either method, including 105 (5.7%) only by vaginal swab and 53 (2.9%) only by cervical swab. Vaginal and cervical samples were 91.4% concordant (κ = 0.73 [95% confidence interval, 0.69-0.77], P < 0.001). Overall, 133 HPV-positive women (29.9%) had CIN-I, whereas 32 (7.2%) had ≥CIN-II. The sensitivity of vaginal swabs was similar to cervical swabs for detecting ≥CIN-I (89.1% vs. 87.9%, respectively; P = 0.75) lesions and ≥CIN-II disease (87.5% vs. 96.9%, P = 0.18). Eighteen of 19 cases of CIN-III and invasive cancer were found by both methods. CONCLUSIONS Human papillomavirus screening via self-collected vaginal swabs or physician-collected cervical swabs are feasible options in this Haitian population. The agreement between cervical and vaginal samples was high, suggesting that vaginal sample-only algorithms for screening could be effective for improving screening rates in this underscreened population.

Prevalence, Predictors, and Same Day Treatment of Positive VIA Enhanced by Digital Cervicography and Histopathology Results in a Cervical Cancer Prevention Program in Cameroon. PLoS One 2016; 11:e0157319. [PMID: 27280882 PMCID: PMC4900564 DOI: 10.1371/journal.pone.0157319] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2016] [Accepted: 05/29/2016] [Indexed: 11/25/2022] Open
Abstract
Background In 2007, the Cameroon Baptist Convention Health Services (CBCHS) implemented a screen-and-treat cervical cancer prevention program using visual inspection with acetic acid enhanced by digital cervicography (VIA-DC). Methods We retrospectively analyzed 46,048 medical records of women who received care through the CBCHS Women’s Health Program from 2007 through 2014 to determine the prevalence and predictors of positive VIA-DC, rates of same day treatment, and cohort prevalence of invasive cervical cancer (ICC). Results Of the 44,979 women who were screened for cervical cancer, 9.0% were VIA-DC-positive, 66.8% were VIA-DC-negative, 22.0% were VIA-DC-inadequate (normal ectocervix, but portions of the transformation zone were obscured), and 2.2% were VIA-DC-uncertain (cervical abnormalities confounding VIA-DC interpretation). Risk factors significantly associated with VIA-DC-positive screen were HIV-positivity, young age at sexual debut, higher lifetime number of sexual partners, low education status and higher gravidity. In 2014, 31.1% of women eligible for cryotherapy underwent same day treatment. Among the 32,788 women screened from 2007 through 2013, 201 cases of ICC were identified corresponding to a cohort prevalence of 613 per 100,000. Conclusions High rate of VIA-DC-positive screens suggests a significant burden of potential cervical cancer cases and highlights the need for expansion of cervical cancer screening and prevention throughout the 10 regions of Cameroon. VIA-DC-inadequate rates were also high, especially in older women, and additional screening methods are needed to confirm whether these results are truly negative. In comparison to similar screening programs in sub-Saharan Africa there was low utilization of same day cryotherapy treatment. Further studies are required to characterize possible program specific barriers to treatment, for example cultural demands, health system challenges and cost of procedure. The prevalence of ICC among women who presented for screening was high and requires further investigation.

Abstract
BACKGROUND Women living in Africa experience the highest burden of cervical cancer. Research and investment to improve vaccination, screening, and treatment efforts are critically needed. We systematically reviewed and characterized recent research within a broader public health framework to organize and assess the range of cervical cancer research in Africa. METHODS We searched online databases and the Internet for published articles and cervical cancer reports in African countries. Inclusion criteria included publication between 2004 and 2014, cervical cancer-related content pertinent to one of the four public health categories (primary, secondary, tertiary prevention or quality of life), and conducted in or specifically relevant to countries or regions within the African continent. The study design, geographic region/country, focus of research, and key findings were documented for each eligible article and summarized to illustrate the weight and research coverage in each area. Publications with more than one focus (e.g. secondary and tertiary prevention) were categorized by the primary emphasis of the paper. Research specific to HIV-infected women or focused on feasibility issues was delineated within each of the four public health categories. RESULTS A total of 380 research articles/reports were included. The majority (54.6 %) of cervical cancer research in Africa focused on secondary prevention (i.e., screening). The number of publication focusing on primary prevention (23.4 %), particularly HPV vaccination, increased significantly in the past decade. Research regarding the treatment of precancerous lesions and invasive cervical cancer is emerging (17.6 %), but infrastructure and feasibility challenges in many countries have impeded efforts to provide and evaluate treatment. Studies assessing aspects of quality of life among women living with cervical cancer are severely limited (4.1 %). Across all categories, 11.3 % of publications focused on cervical cancer among HIV-infected women, while 17.1 % focused on aspects of feasibility for cervical cancer control efforts. CONCLUSIONS Cervical cancer research in African countries has increased steadily over the past decade, but more is needed. Tertiary prevention (i.e. treatment of disease with effective medicine) and quality of life of cervical cancer survivors are two severely under-researched areas. Similarly, there are several countries in Africa with little to no research ever conducted on cervical cancer.

Abstract
Purpose Almost nine of 10 deaths resulting from cervical cancer occur in low-income countries. Visual inspection under acetic acid (VIA) is an evidence-based, cost-effective approach to cervical cancer screening (CCS), but challenges to effective implementation include health provider training costs, provider turnover, and skills retention. We hypothesized that a smartphone camera and use of cervical image transfer for real-time mentorship by experts located distantly across a closed user group through a commercially available smartphone application would be both feasible and effective in enhancing VIA skills among CCS providers in Tanzania. Methods We trained five nonphysician providers in semirural Tanzania to perform VIA enhanced by smartphone cervicography with real-time trainee support from regional experts. Deidentified images were sent through a free smartphone application on the available mobile telephone networks. Our primary outcomes were feasibility of using a smartphone camera to perform smartphone-enhanced VIA and level of agreement in diagnosis between the trainee and expert reviewer over time. Results Trainees screened 1,072 eligible women using our methodology. Within 1 month of training, the agreement rate between trainees and expert reviewers was 96.8%. Providers received a response from expert reviewers within 1 to 5 minutes 48.4% of the time, and more than 60% of the time, feedback was provided by regional expert reviewers in less than 10 minutes. Conclusion Our method was found to be feasible and effective in increasing health care workers’ skills and accuracy. This method holds promise for improved quality of VIA-based CCS programs among health care providers in low-income countries.

Cervical Cancer Screening Service Uptake and Associated Factors among Age Eligible Women in Mekelle Zone, Northern Ethiopia, 2015: A Community Based Study Using Health Belief Model. PLoS One 2016; 11:e0149908. [PMID: 26963098 PMCID: PMC4786115 DOI: 10.1371/journal.pone.0149908] [Citation(s) in RCA: 98] [Impact Index Per Article: 12.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2015] [Accepted: 02/05/2016] [Indexed: 12/26/2022] Open
Abstract
Introduction Cervical cancer is the third most common cancer among women worldwide, with about 500,000 new patients diagnosed and over 250,000 deaths every year. Cervical cancer screening offers protective benefits and is associated with a reduction in the incidence of invasive cervical cancer and cervical cancer mortality. But there is very low participation rate in screening for cervical cancer among low and middle-income countries. Objective This study aimed to determine cervical cancer screening service uptake and its associated factor among age eligible women in Mekelle zone, northern Ethiopia, 2015. Methods A community based cross-sectional study was conducted in Mekelle zone among age eligible women from February to June 2015. Systematic sampling technique was used to select 1286 women in to the study. A pre-tested structured questionnaire was used to collect relevant data. Data was entered and cleaned using EPINFO and analyzed using SPSS version 20 software package. Bivariate and Multivariate logistic regression was performed to assess association between dependent and independent variables with 95% CI and p-value less than 0.05 was set for association. Results The study revealed that among 1186 age eligible women, only 235(19.8%) have been screened for cervical cancer. Age (AOR = 1.799, 95%CI = 1.182–2.739), history of multiple sexual partners (AOR = 1.635, 95%CI = 1.094–2.443), history of sexually transmitted disease (AOR = 1.635,95%CI = 1.094–2.443), HIV sero status (AOR = 5.614, 95%CI = 2.595–12.144), perceived susceptibility to cervical cancer (AOR = 2.225, 95%CI = 1.308–3.783), perceived barriers to premalignant cervical lesions screening (AOR = 2.256, 95%CI = 1.447–3.517) and knowledge on cervical cancer and screening (AOR = 2.355, 95%CI = 1.155–4.802) were significant predictors of cervical cancer screening service uptake. Conclusion Magnitude of cervical cancer screening service uptake among age eligible women is still unacceptably low. Age of the women, history of multiple sexual partners and sexually transmitted disease, HIV sero-positivity, Knowledge, Perceived susceptibility and Perceived Barrier were important predictors of cervical cancer screening service uptake.

Abstract
OBJECTIVE The objective of this study was to assess the conditions under which Zambian women with a history of cervical cancer screening by visual inspection with acetic acid might switch to human papillomavirus-based testing in the future. MATERIALS AND METHODS We conducted a choice-based conjoint survey in a sample of women recently screened by visual inspection in Lusaka, Zambia. The screening attribute considered in hypothetical-choice scenarios included screening modality, sex and age of the examiner, whether screening results would be presented visually, distance from home to the clinic, and wait time for results. RESULTS Of 238 women in the sample, 208 (87.4%) provided responses sufficiently reliable for analysis. Laboratory testing on a urine sample was the preferred screening modality, followed by visual screening, laboratory testing on a self-collected vaginal specimen, and laboratory testing on a nurse-collected cervical specimen. Market simulation suggested that only 39.7% (95% CI = 33.8-45.6) of the respondents would prefer urine testing offered by a female nurse in her 30s over visual inspection of the cervix conducted by a male nurse in his 20s if extra wait time were as short as 1 hour and the option of viewing how their cervix looks like were not available. CONCLUSIONS Our study suggests that, for some women, the level of preference for human papillomavirus-based screening strategies may depend highly on the process and conditions of service delivery.

Abstract
BACKGROUND Cervical cancer screening efforts linked to HIV/AIDS care programs are being expanded across sub-Saharan Africa. Evidence on the age distribution and determinants of invasive cervical cancer (ICC) cases detected in such programs is limited. METHODS We analyzed program operations data from the Cervical Cancer Prevention Program in Zambia, the largest public sector programs of its kind in sub-Saharan Africa. We examined age distribution patterns by HIV serostatus of histologically confirmed ICC cases and used multivariable logistic regression to evaluate independent risk factors for ICC among younger (≤35 years) and older (>35 years) women. RESULTS Between January 2006 and April 2010, of 48,626 women undergoing screening, 571 (1.2%) were diagnosed with ICC, including 262 (46%) HIV seropositive (median age: 35 years), 131 (23%) HIV seronegative (median age: 40 years), and 178 (31%) of unknown HIV serostatus (median age: 38 years). Among younger (≤35 years) women, being HIV seropositive was associated with a 4-fold higher risk of ICC [adjusted odds ratio = 4.1 (95% confidence interval: 2.8, 5.9)] than being HIV seronegative. The risk of ICC increased with increasing age among HIV-seronegative women and women with unknown HIV serostatus, but among HIV-seropositive women, the risk peaked around age 35 and nonsignificantly declined with increasing ages. Other factors related to ICC included being married (vs. being unmarried/widowed) in both younger and older women, and with having 2+ (vs. ≤1) lifetime sexual partners among younger women. CONCLUSIONS HIV infection seems to have increased the risk of cervical cancer among younger women in Zambia, pointing to the urgent need for expanding targeted screening interventions.

Abstract
Background HIV infection increases a woman’s risk for cervical cancer, and cervical cancer incidence and mortality rates are higher in countries with high HIV prevalence and limited resources for screening. Visual inspection with acetic acid (VIA) allows screening and treatment of cervical lesions in a single-visit approach (SVA), but data on its performance in HIV-infected women are limited. This study’s objective was to examine cervical cancer screening using VIA/SVA in programs serving HIV-infected women. Methods A VIA/SVA program with cryotherapy for VIA-positive lesions was implemented in Côte d’Ivoire, Guyana, and Tanzania from 2009 to 2012. The effect of HIV status on VIA positivity and on presence of cryotherapy-eligible lesions was examined using a cross-sectional study design, with Chi-square tests for comparisons and constructed multivariate logistic regression models. A P-value of < 0.05 was significant. Findings VIA was performed on 34,921 women, 10% (3,580) were VIA positive; 2,508 (85%) eligible women received cryotherapy during the same visit; only 234 (52%) of those who postponed returned for treatment; 622 (17%) VIA-positive women had lesions too large to be treated with cryotherapy and were referred for excisional treatment. In multivariate analysis—controlling for HIV status, location of the screening clinic, facility location, facility type, and country—compared to HIV-uninfected/unknown women, HIV-infected women had higher odds of being VIA positive (OR 1.95, 95% CI 1.76, 2.16, P<0.0001) and of having large lesions requiring referral (OR 1.93, 95% CI 1.49, 2.51, P< 0.0001). Minor treatment complications occurred in 19 of 3,032 (0.63%) women; none required further intervention. Conclusions This study found that compared to HIV-uninfected/unknown women, HIV-infected women had nearly twice the odds of being VIA-positive and to require referral for large lesions. SVA was safe and resulted in significant reductions in loss to follow-up. There is increased need for excisional treatment in countries with high HIV prevalence.

Abstract
OBJECTIVES Cervical cancer is increasing but underestimated in developing countries. We calculated the observed and expected incidence of cervical cancer in Lusaka and Southern and Western provinces of Zambia. METHODS/MATERIALS Data for 2007 to 2012 were obtained for the 3 provinces. Data included age, residence, year of diagnosis, marital status, occupation, human immunodeficiency virus (HIV), stage, radiotherapy, and chemotherapy. Expected incidence in Southern and Western provinces was calculated based on observed incidence for Lusaka province, adjusting for HIV. RESULTS Crude and age-standardized incidence rates (ASRs) in Lusaka were 2 to 4 times higher than incidence in the other 2 provinces. Lusaka had a rate of 54.1 per 10(5) and ASR of 82.1 per 10(5) in the age group of 15 to 49 years. The Southern province had a rate of 17.1 per 10(5) and ASR of 25.5 per 10(5); the Western province had a rate of 12.3 per 10(5) and ASR rate of 17.2 per 10(5). The observed cervical cancer incidence rates in the Southern and Western provinces were lower than the rate in Lusaka, possibly because of the uncertainty of underreporting/underdiagnosis or actual lower risk for reasons yet unclear. The HIV seroprevalence rates in patients from the 3 provinces were 46% to 93% higher than seroprevalence in the respective general populations. CONCLUSIONS Cervical cancer is significantly underestimated in Zambia, and HIV has a significant role in pathogenesis. Future studies should establish methods for case ascertainment and better utilization of hospital- and population-based registries in Zambia and other similar developing countries.

Abstract
People living with human immunodeficiency virus (HIV) are living longer since the advent of effective combined antiretroviral therapy (cART). While cART substantially decreases the risk of developing some cancers, HIV-infected individuals remain at high risk for Kaposi sarcoma, lymphoma, and several solid tumors. Currently HIV-infected patients represent an aging group, and malignancies have become a leading cause of morbidity and mortality. Tailored cancer-prevention strategies are needed for this population. In this review we describe the etiologic agents and pathogenesis of common malignancies in the setting of HIV, as well as current evidence for cancer prevention strategies and screening programs.

The burden of cervical pre-cancer and cancer in HIV positive women in Zambia: a modeling study. BMC Cancer 2015.

Abstract
Background HIV infection is associated with a higher incidence of precancerous cervical lesions and their progression to invasive cervical cancer (ICC). Zambia is a global epicenter of HIV and ICC, yet the overall burden of cervical pre-cancer [cervical intraepithelial neoplasia 3 (CIN3)] and ICC among its HIV positive adult female population is unknown. The objective of this study was to determine the burden of cervical disease among HIV positive women in Zambia by estimating the number with CIN3 and ICC. Methods We conducted a cross-sectional study among 309 HIV positive women attending screening in Lusaka (Zambia’s most populated province) to measure the cervical disease burden by visual inspection with acetic acid enhanced by digital cervicography (DC), cytology, and histology. We then used estimates of the prevalence of CIN3 and ICC from the cross-sectional study and Spectrum model-based estimates for HIV infection among Zambian women to estimate the burden of CIN3 and ICC among HIV positive women nationally. Results Over half (52 %) of the study participants screened positive by DC, while 45 % had cytologic evidence of high grade squamous intraepithelial lesions (SIL) or worse. Histopathologic evaluation revealed that 20 % of women had evidence of CIN2 or worse, 11 % had CIN3 or worse, and 2 % had ICC. Using the Spectrum model, we therefore estimate that 34,051 HIV positive women in Zambia have CIN3 and 7,297 have ICC. Conclusions The DC, cytology, and histology results revealed a large cervical disease burden in this previously unscreened HIV positive population. This very large burden indicates that continued scale-up of cervical cancer screening and treatment is urgently needed.

Abstract
BACKGROUND Cervical cancer is the commonest cancer amongst African women, and yet preventative services are often inadequate. AIM The purpose of the study was to assess the safety, acceptability and feasibility of visual inspection with acetic acid and cervicography (VIAC) followed by cryotherapy or a loop electrical excision procedure (LEEP) at a single visit for prevention of cancer of the cervix. SETTING The United Bulawayo Hospital, Zimbabwe. METHODS The study was descriptive, using retrospective data extracted from electronic medical records of women attending the VIAC clinic. Over 24 months 4641 women visited the clinic and were screened for cervical cancer using VIAC. Cryotherapy or LEEP was offered immediately to those that screened positive. Treated women were followed up at three months and one year. RESULTS The rate of positive results on VIAC testing was 10.8%. Of those who were eligible, 17.0% received immediate cryotherapy, 44.1% received immediate LEEP, 1.9% delayed treatment, and 37.0% were referred to a gynaecologist. No major complications were recorded after cryotherapy or LEEP. Amongst those treated 99.5% expressed satisfaction with their experience. Only 3.2% of those treated at the clinic had a positive result on VIAC one year later. The service was shown to be feasible to sustain over time with the necessary consumables. There were no service-related treatment postponements and the clinic staff and facility were able to meet the demand for the service. CONCLUSION A single-visit approach using VIAC, followed by cryotherapy or LEEP, proved to be safe, acceptable and feasible in an urban African setting in Bulawayo, Zimbabwe. Outcomes a year later suggested that treatment had been effective.
