Primary Tumors of the Brain and Central Nervous System in Adults and Children in Sub-Saharan Africa: Protocol for a Scoping Review. JMIR Res Protoc 2025; 14:e66978. [PMID: 40273436 PMCID: PMC12062764 DOI: 10.2196/66978] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2024] [Revised: 01/19/2025] [Accepted: 03/10/2025] [Indexed: 04/26/2025] Open
Abstract
BACKGROUND In Sub-Saharan Africa (SSA), clinical and research investments for oncology screening, diagnosis, and therapy are exceedingly modest, compared to those in higher-income regions. Diseases that are difficult to prevent or treat, such as primary brain and central nervous system (CNS) tumors, are especially challenging in low-resource settings. OBJECTIVE In order to review and synthesize existing evidence to identify research and service gaps, we will conduct a scoping review to assess epidemiological data, clinical series, and health outcomes associated with brain and CNS tumors in SSA. METHODS This scoping review is guided by the Scoping Review Chapter of the JBI (Joanna Briggs Institute) Manual for Evidence Synthesis. We will search the following databases: Ovid MEDLINE, Embase, Cochrane Library, Scopus, references from salient publications, and the gray literature, the latter focused on the International Agency for Research on Cancer (IARC) and other major global health organizations. We will review titles and abstracts of potentially eligible studies and then full texts by 2 independent reviewers. We will include data from both primary and CNS cancers in persons of all ages. Data will be abstracted independently using piloted data extraction forms, and we will present results according to the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) and PRISMA-P (Preferred Reporting Items for Systematic Review and Meta-Analyses Protocols) guidelines. RESULTS A total of 2857 articles were identified through our search strategy. After title and abstract screening, which was completed on February 23, 2025, by 2 independent reviewers, 222 studies met the eligibility criteria, while 2203 were excluded. Full-text screening began on March 3, 2025, and will be followed by data abstraction and analysis from April 15, 2025, until the end of May 2025. The study is expected to be completed by July 2025. CONCLUSIONS SSA faces substantial challenges in the diagnosis and treatment of CNS tumors due to health care infrastructure limitations, insufficient reporting, and diagnostic supply shortages. The high fatality rates are attributed to underdiagnosis and misdiagnosis as infectious diseases, despite low incidence rates (IRs). The inadequate neurosurgery facilities and pathology resources further complicate the treatment and prognosis. A scoping review will investigate the true burden of underdiagnosis and gaps in outcomes in children and adults in SSA. TRIAL REGISTRATION OSF Registries osf.io/57zvc; https://osf.io/57zvc.

Extensive cervical lesion and treatment outcomes in women with HIV/HPV co-infection. AIDS Res Ther 2024; 21:101. [PMID: 39736742 PMCID: PMC11684313 DOI: 10.1186/s12981-024-00693-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2024] [Accepted: 12/20/2024] [Indexed: 01/01/2025] Open
Abstract
BACKGROUND Cervical cancer is a common cancer worldwide, with > 85% of deaths occurring in Lower- and Middle-Income Countries where resources for screening programs are limited. Women living with HIV (WLHIV) are at increased risk. HPV test-and-treat is a screening strategy where women with HPV are offered ablative treatment of the cervix to reduce the risk of invasive cancer. WLHIV tend to have more extensive cervical lesions, necessitating more specialised surgical treatments. METHOD ACTG A5282 was a randomised, open-label, Phase 2 trial conducted in seven countries that compared a cytology-based screening strategy to HPV test-and-treat for cervical cancer prevention in WLHIV. Women with cervical lesions inappropriate for ablative treatment were assigned to Arm C and underwent colposcopy and directed biopsies. Loop electro-excision procedure was performed if high-grade lesions (bHSIL) were present on cervical biopsies. Women were followed 26 weeks later for repeat evaluations. The Clopper-Pearson exact method was used to construct the 95% confidence interval for the proportion of WLHIV with lesions inappropriate for cryotherapy. Logistic regression models were used to assess the factors associated with these lesions. RESULTS Of 1046 women screened, 156 (88%) were Black/Non-Hispanic, with a median age of 36 years; 80% were on ART, and 73% had an HIV-1 RNA < 200 copies/mL. On cervical colposcopy, 17% (179/1046, 95% CI 14.9-19.4%) had cervical lesions inappropriate for cervical ablation. Among 428 (44%) women with High-risk HPV (hrHPV) detected, 112 (26%, 95% CI 22.2%, 30.5%) had cervical lesions inappropriate for ablative therapy. hrHPV was found more commonly among women having lesions inappropriate for ablative therapy as compared to lesions appropriate for ablative therapy (70% vs 54%, p < .001). Among 128 women with extensive cervical lesions undergoing colposcopic biopsies, 43 (34%) had bHSIL detected. Among women undergoing LEEP treatment of bHSIL, 24% had bHSIL detected 26 weeks later. CONCLUSION Cervical lesions inappropriate for ablative therapy were common among WLHIV. This has implications for cervical cancer programs as these lesions can only be optimally treated with surgical therapies such as loop electroexcision procedures, and the capacity for this procedure should be increased to maximise cervical cancer prevention outcomes.

Internal validation of Automated Visual Evaluation (AVE) on smartphone images for cervical cancer screening in a prospective study in Zambia. Cancer Med 2024; 13:e7355. [PMID: 38872398 PMCID: PMC11176573 DOI: 10.1002/cam4.7355] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 05/20/2024] [Accepted: 05/26/2024] [Indexed: 06/15/2024] Open
Abstract
OBJECTIVES Visual inspection with acetic acid (VIA) is a low-cost approach for cervical cancer screening used in most low- and middle-income countries (LMICs) but, similar to other visual tests, is subjective and requires sustained training and quality assurance. We developed, trained, and validated an artificial-intelligence-based "Automated Visual Evaluation" (AVE) tool that can be adapted to run on smartphones to assess smartphone-captured images of the cervix and identify precancerous lesions, helping augment VIA performance. DESIGN Prospective study. SETTING Eight public health facilities in Zambia. PARTICIPANTS A total of 8204 women aged 25-55. INTERVENTIONS Cervical images captured on commonly used low-cost smartphone models were matched with key clinical information including human immunodeficiency virus (HIV) and human papillomavirus (HPV) status, plus histopathology analysis (where applicable), to develop and train an AVE algorithm and evaluate its performance for use as a primary screen and triage test for women who are HPV positive. MAIN OUTCOME MEASURES Area under the receiver operating curve (AUC); sensitivity; specificity. RESULTS As a general population screening tool for cervical precancerous lesions, AVE identified cases of cervical precancerous and cancerous (CIN2+) lesions with high performance (AUC = 0.91, 95% confidence interval [CI] = 0.89-0.93), which translates to a sensitivity of 85% (95% CI = 81%-90%) and specificity of 86% (95% CI = 84%-88%) based on maximizing the Youden's index. This represents a considerable improvement over naked eye VIA, which as per a meta-analysis by the World Health Organization (WHO) has a sensitivity of 66% and specificity of 87%. For women living with HIV, the AUC of AVE was 0.91 (95% CI = 0.88-0.93), and among those testing positive for high-risk HPV types, the AUC was 0.87 (95% CI = 0.83-0.91). CONCLUSIONS These results demonstrate the feasibility of utilizing AVE on images captured using a commonly available smartphone by nurses in a screening program, and support our ongoing efforts for moving to more broadly evaluate AVE for its clinical sensitivity, specificity, feasibility, and acceptability across a wider range of settings. Limitations of this study include potential inflation of performance estimates due to verification bias (as biopsies were only obtained from participants with visible aceto-white cervical lesions) and due to this being an internal validation (the test data, while independent from that used to develop the algorithm was drawn from the same study).

Abstract
OBJECTIVE To examine screening outcomes for a rural screen-and-treat site as well as the referral completion rate, outreach programming, and screening costs. METHODS A retrospective cross-sectional analysis of demographic information and screening outcomes for all women screened at a rural screen-and-treat site between August 2011 and December 2018 was conducted. Referral completion rate for women with suspected cervical cancer was calculated for 2018. RESULTS A total of 10 157 screenings were conducted during the study period. Median age was 35 years and median parity was 5. In all, 545 (5.35%) women were positive on visual inspection with acetic acid (VIA+), and 461 (91.1%) of 506 eligible women received cryotherapy. In 2018, 93 women were referred for suspected cancer to the zonal referral center, but only 10 (10.8%) presented for treatment. Mean screening cost was US$ 6.62 per person. CONCLUSION VIA+ rate was comparable to rates at urban sites in Tanzania, and outreach was an important component of screening. In contrast to other reports, few women suspected of having cancer reached treatment after being referred. Although the low cost of screening highlights the feasibility of rural screen-and-treat sites, additional research is needed to improve completion of referrals to a higher level of care.

Abstract
Objective The study was undertaken for comparing the colposcopy directed punch versus loop excision biopsy technique in order to get the most précised sample for study as well as comparing the complications associated with them. Materials and Methods The prospective clinical study was conducted on 50 women of age group 20-80 years. Women who were found to have a Reid colposcopic index of high grade disease, low grade disease or invasive disease recognized as the patients needed biopsy. They were randomly divided into either the punch biopsy forceps group (PB group) or the round loop electrode group (LE group). Result The quality of tissue of the LE group was found significantly better than the tissue quality of PB group based on the size, site and tissue damaged measures. Both the groups were found to have the same cytology report as well as colposcopic diagnosis and histology reports. Mild degree of bleeding has been reported as a frequent complication in LEEP and punch biopsy. The VAS pain score associated in each procedure was found to be 2.4 and 2.8, respectively, in both groups with no significant difference. Conclusion The present study has concluded that the quality of tissue from the LEEP biopsy electrode was better than the punch biopsy forceps with no difference in the pain score, and it could be suggested that use of the round loop electrode in CDB provides good quality tissue to evaluate the histology.

Implementation research on noncommunicable disease prevention and control interventions in low- and middle-income countries: A systematic review. PLoS Med 2022; 19:e1004055. [PMID: 35877677 PMCID: PMC9359585 DOI: 10.1371/journal.pmed.1004055] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/08/2021] [Revised: 08/08/2022] [Accepted: 06/21/2022] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND While the evidence for the clinical effectiveness of most noncommunicable disease (NCD) prevention and treatment interventions is well established, care delivery models and means of scaling these up in a variety of resource-constrained health systems are not. The objective of this review was to synthesize evidence on the current state of implementation research on priority NCD prevention and control interventions provided by health systems in low- and middle-income countries (LMICs). METHODS AND FINDINGS On January 20, 2021, we searched MEDLINE and EMBASE databases from 1990 through 2020 to identify implementation research studies that focused on the World Health Organization (WHO) priority NCD prevention and control interventions targeting cardiovascular disease, cancer, diabetes, and chronic respiratory disease and provided within health systems in LMICs. Any empirical and peer-reviewed studies that focused on these interventions and reported implementation outcomes were eligible for inclusion. Given the focus on this review and the heterogeneity in aims and methodologies of included studies, risk of bias assessment to understand how effect size may have been compromised by bias is not applicable. We instead commented on the distribution of research designs and discussed about stronger/weaker designs. We synthesized extracted data using descriptive statistics and following the review protocol registered in PROSPERO (CRD42021252969). Of 9,683 potential studies and 7,419 unique records screened for inclusion, 222 eligible studies evaluated 265 priority NCD prevention and control interventions implemented in 62 countries (6% in low-income countries and 90% in middle-income countries). The number of studies published has been increasing over time. Nearly 40% of all the studies were on cervical cancer. With regards to intervention type, screening accounted for 49%, treatment for 39%, while prevention for 12% (with 80% of the latter focusing on prevention of the NCD behavior risk factors). Feasibility (38%) was the most studied implementation outcome followed by adoption (23%); few studies addressed sustainability. The implementation strategies were not specified well enough. Most studies used quantitative methods (86%). The weakest study design, preexperimental, and the strongest study design, experimental, were respectively employed in 25% and 24% of included studies. Approximately 72% of studies reported funding, with international funding being the predominant source. The majority of studies were proof of concept or pilot (88%) and targeted the micro level of health system (79%). Less than 5% of studies report using implementation research framework. CONCLUSIONS Despite growth in implementation research on NCDs in LMICs, we found major gaps in the science. Future studies should prioritize implementation at scale, target higher levels health systems (meso and macro levels), and test sustainability of NCD programs. They should employ designs with stronger internal validity, be more conceptually driven, and use mixed methods to understand mechanisms. To maximize impact of the research under limited resources, adding implementation science outcomes to effectiveness research and regional collaborations are promising.

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
OBJECTIVE To determine the utility of detecting endocervical cervical intraepithelial neoplasia (CIN) 2+ with endocervical curettage (ECC) and treating with loop electrosurgical excision procedure (LEEP) plus top hat (+TH) among women with HIV. METHODS Cytology was followed by coloscopy-directed biopsy if participants had HSIL or ASC-H and biopsy plus ECC if there were glandular cells present. CIN2/3 on ECC and/or inadequate colposcopy (ENL) was treated with LEEP+TH, while CIN2/3 on ectocervix (ECL) received LEEP alone. Recurrent CIN2+ were compared over a 2-year follow-up. RESULTS Of 5330 participants, 160 underwent ECC, 98 were CIN2/3 on ECC, and 77 received LEEP+TH. ECC detected 15 (9%) more women with CIN2/3 than biopsy alone. Women were more likely to have ENL if they were older (≥45 vs <35 years) (adjusted relative risk [aRR] 2.14; P = 0.009) and on antiretroviral treatment longer (≥2 vs <2 years) (aRR 3.97; P < 0.001). Over the 2-year follow-up, 35 (29%) ENL had recurrent CIN2+ after TH compared to 19 (24%) ECL after LEEP (hazard ratio 1.32; 95% confidence interval 0.75-2.31; P = 0.338). CONCLUSION Among HIV-infected women, adding ECC did not increase detection of pre-cancerous disease significantly and treatment with LEEP+TH for ENL was comparable to treatment with LEEP for ECL.

Abstract
Purpose Treatment of cervical precancer is the primary aim in secondary prevention of cervical cancer. The purpose of this study was to examine factors associated with treatment uptake among women with acetic acid/Lugol’s iodine positive lesions identified by digital cervicography (DC) in a cervical cancer prevention program in Cameroon. Patients and Methods We conducted a cross-sectional survey of medical records from 2013 to 2018 of 755 women in Cameroon who screened positive with acetic acid/Lugol’s iodine in 2013. Results Of the 755 women, 422 (55.9%) had treatment/biopsy on the same day or followed up later, but only 344 (45.6%) received treatment/biopsy and 333 (44.1%) were lost to follow-up. Overall, 180 (52.3%) of the 344 women were treated/biopsied the same day they were screened, and 164 (47.7%) were treated/biopsied after the initial visit. Women aged 30–49 and HIV-positive women were significantly more likely to have received treatment or returned for treatment than women less than 30 and HIV-negative women. Of the 266 women who followed up at a later date, the lesions of 78 (29.3%) women regressed spontaneously without treatment. Women with low-grade lesions, HIV-negative women and women who had follow-up more than a year after the initial exam were significantly more likely to have spontaneous regression with regression rates of 30.6%, 32.1% and 62.2%, respectively (p<0.001). Age was not a significant determinant of spontaneous regression (p=0.149). Conclusion Efforts to increase treatment uptake are needed in this population, including adherence to same day “See and treat” policies.

Abstract
Introduction We aimed to quantify health outcomes and programmatic implications of scaling up cervical cancer (CC) screening and treatment options for women living with HIV in care aged 18–65 in Kenya. Methods Mathematical model comparing from 2020 to 2040: (1) visual inspection with acetic acid (VIA) and cryotherapy (Cryo); (2) VIA and Cryo or loop excision electrical procedure (LEEP), as indicated; (3) human papillomavirus (HPV)-DNA testing and Cryo or LEEP; and (4) enhanced screening technologies (either same-day HPV-DNA testing or digitally enhanced VIA) and Cryo or LEEP. Outcomes measured were annual number of CC cases, deaths, screening and treatment interventions, and engaged in care (numbers screened, treated and cured) and five yearly age-standardised incidence. Results All options will reduce CC cases and deaths compared with no scale-up. Options 1–3 will perform similarly, averting approximately 28 000 (33%) CC cases and 7700 (27%) deaths. That is, VIA screening would yield minimal losses to follow-up (LTFU). Conversely, LTFU associated with HPV-DNA testing will yield a lower care engagement, despite better diagnostic performance. In contrast, option 4 would maximise health outcomes, averting 43 200 (50%) CC cases and 11 800 (40%) deaths, given greater care engagement. Yearly rescreening with either option will impose a substantial burden on the health system, which could be reduced by spacing out frequency to three yearly without undermining health gains. Conclusions Beyond the specific choice of technologies to scale up, efficiently using available options will drive programmatic success. Addressing practical constraints around diagnostics’ performance and LTFU will be key to effectively avert CC cases and deaths.

Abstract
Background: In 2015, a See and Treat cervical cancer screening program was implemented at a local HIV clinic in Limpopo, South Africa, where infrastructure limited adequate Pap smear usability. Objectives: The purpose of this evaluation was to determine the quality and sustainability of the implemented program. Methods: A mixed-methods program analysis was conducted at 18-months post implementation. Data collection techniques included in-depth interviews of staff and patients, observation of healthcare workers delivering screening, and review of charts and patient logs. Findings: Eighteen in-depth interviews revealed improved cervical cancer screening understanding and awareness. Privacy concerns and negative perceptions of medical care were barriers to screening. Informal observations revealed continued clinical competence among healthcare workers who had been previously trained. Review of charts demonstrated positive correlation between VIA and Pap smear results. In evaluating loss to attrition, about half of the first cohort of patients were lost to follow-up. VIAs and Pap smears were offered on an ongoing basis, and month-over-month change for overlapping four months of programming between 2015 and 2016 showed a 4.4% negative change in number of Pap smears and a 57% negative change in VIAs. Conclusion: Our evaluation reveals successful integration of See and Treat into current clinic services in rural South Africa and increased awareness of cervical cancer among health workers and participants. Program sustainability was challenging to assess as many patients were lost to follow-up, given the migrant and transient population attending this clinic. Acceptance by health workers and patients alike is vital for the long-term impact on cervical cancer incidence in this region.

Abstract
Aim: Invasive cervical cancer is proceeded by a phase of preinvasive disease that is slow to progress and can be detected, treated, and collectively referred to as cervical intraepithelial neoplasia (CIN). Several excisional and ablative treatments for CIN have been studied, with loop electrosurgical excision procedure (LEEP) and cryotherapy being the two most commonly utilized. The objective of this systematic review and meta-analysis of randomized controlled trials (RCTs) was to compare the compare harms and benefits of LEEP versus cryotherapy in women with CIN. Methods: Electronic databases were searched from their inception until May 2018. We included all RCTs comparing cryotherapy versus LEEP in women with CIN. We included trials evaluating both HIV-seropositive and HIV-seronegative women. The primary outcome was the persistence of the disease at 6-month follow-up. Meta-analysis was performed using the random-effects model to produce summary treatment effects in terms of relative risk (RR) with 95% confidence interval (CI). Results: Four trials, including 1035 women with CIN, were identified as relevant and included in the meta-analysis. Women who received LEEP for CIN had a significantly lower persistence at 6-month follow-up biopsy (RR: 0.87, 95% CI: 0.76–0.99) and significantly lower recurrence at 12-month follow-up biopsy (RR: 0.91, 95% CI: 0.84–0.99) compared to those who received cryotherapy. No between-group differences were found in the complications rate, but the analyses were not powered for these outcomes. Conclusions: In women with CIN, treatment with LEEP was associated with a significantly lower risk of persistence disease at 6 months and recurrence disease at 12 months compared to treatment with cryotherapy.

Abstract
OBJECTIVE As the burden of chronic non-communicable diseases (NCDs) rises across sub-Saharan Africa (SSA), global donors and governments are exploring strategies to integrate HIV and NCD care. Implementation science is an emerging research paradigm that can help such programs achieve health impact at scale. We define implementation science as a systematic, scientific approach to ask and answer questions about how to deliver what works in populations who need it with greater speed, appropriate fidelity, efficiency, and relevant coverage. We identified achievements and gaps in the application of implementation science to HIV/NCD integration, developed an HIV/NCD implementation science research agenda, and detailed opportunities for capacity building and training. DESIGN We conducted a systematic review of the application of implementation science methods to integrated HIV/NCD programs in SSA. METHODS We searched PubMed, CINAHL, PsycINFO, and EMBASE for evaluations of integrated programs in SSA reporting at least one implementation outcome. RESULTS We identified 31 eligible studies. We found that most studies used only qualitative, economic, or impact evaluation methods. Only one study used a theoretical framework for implementation science. Acceptability, feasibility, and penetration were the most frequently reported implementation outcomes. Adoption, appropriateness, cost, and fidelity were rare; sustainability was not evaluated. CONCLUSIONS Implementation science has a promising role in supporting HIV/NCD integration, although its impact will be limited unless theoretical frameworks, rigorous study designs, and reliable measures are employed. To help support use of implementation science, we need to build sustainable implementation science capacity. Doing so in SSA and supporting implementation science investigators can help expedite HIV/NCD integration.

Abstract
Women living with HIV in Africa are at increased risk to be co-infected with Human Papilloma Virus (HPV), persistent high risk (HR) HPV infection and bacterial vaginosis (BV), which compounds HPV persistence, thereby increasing the risk for cervical dysplasia. New guidance from WHO in 2014 advocating for a “screen and treat” approach in resource poor settings is becoming a more widely recommended screening tool for cervical cancer prevention programs in such contexts. This review article summarizes the risk factors to be considered when designing a primary and secondary cervical prevention program in a post-vaccination era for HIV-infected women in Kenya. This review article is based on our prior research on the epidemiology of pHR/HR-HPV genotypes in HIV-infected women and CIN 2 + in Kenya and other sub-Saharan contexts. In order to contextualize the findings, a literature search was carried out in March 2017 by means of four electronic databases: PUBMED, EMBASE, SCOPUS, and PROQUEST. Risk factors for potential (pHR)/HR HPV acquisition, including CD4 count, HAART initiation, Female Sex Worker status (FSW) and BV need to be considered. Furthermore, there may be risk factors for abnormal cytology, including FSW status, multiple potential (p)HR/HR HPV genotypes, which may require that HIV-infected women be subjected to screening at more frequent intervals than the three year recommended by the WHO. The quadruple synergistic interaction between HIV, HPV and BV and its related cervicitis may need to be reflected within a larger prevention framework at the community level. The opportunities brought forth by the roll out of HAART could lead to task shifting of HIV-HPV-BV care to nurses, which may increase access in poorly-served areas. Bacterial Vaginosis treatment should be an integral component of cervical cancer prevention. A larger cervical cancer prevention framework at the community level is needed. Task shifting to nurses of Bacterial Vaginosis management in HIV-HPV co-infected women should be explored.

Abstract
BACKGROUND Mortality associated with cervical cancer is a public health concern for women, particularly in HIV-seropositive women in resource-limited countries. HIV-seropositive women are at a higher risk of high-grade cervical precancer, which can eventually progress to invasive carcinoma as compared to HIV-seronegative women. It is imperative to identify effective treatment methods for high-grade cervical precursors among HIV-seropositive women. OBJECTIVE Randomized controlled trial data are needed comparing cryotherapy vs loop electrosurgical excision procedure treatment efficacy in HIV-seropositive women. Our primary aim was to compare the difference in the efficacy of loop electrosurgical excision procedure vs cryotherapy for the treatment of high-grade cervical intraepithelial neoplasia (grade ≥2) among HIV-seropositive women by conducting a randomized clinical trial. STUDY DESIGN HIV-seropositive women (n = 166) aged 18-65 years with histology-proven cervical intraepithelial neoplasia grade ≥2 were randomized (1:1) to cryotherapy or loop electrosurgical excision procedure treatment at a government hospital in Johannesburg. Treatment efficacy was compared using 6- and 12-month cumulative incidence posttreatment of: (1) cervical intraepithelial neoplasia grade ≥2; (2) secondary endpoints of histologic cervical intraepithelial neoplasia grade ≥3 and grade ≥1; and (3) high-grade and low-grade cervical cytology. The study was registered (ClinicalTrials.govNCT01723956). RESULTS From January 2010 through August 2014, 166 participants were randomized (86 loop electrosurgical excision procedure; 80 cryotherapy). Cumulative cervical intraepithelial neoplasia grade ≥2 incidence was higher for cryotherapy (24.3%; 95% confidence interval, 16.1-35.8) than loop electrosurgical excision procedure at 6 months (10.8%; 95% confidence interval, 5.7-19.8) (P = .02), although by 12 months, the difference was not significant (27.2%; 95% confidence interval, 18.5-38.9 vs 18.5%; 95% confidence interval, 11.6-28.8, P = .21). Cumulative cervical intraepithelial neoplasia grade ≥1 incidence for cryotherapy (89.2%; 95% confidence interval, 80.9-94.9) did not differ from loop electrosurgical excision procedure (78.3%; 95% confidence interval, 68.9-86.4) at 6 months (P = .06); cumulative cervical intraepithelial neoplasia grade ≥1 incidence by 12 months was higher for cryotherapy (98.5%; 95% confidence interval, 92.7-99.8) than loop electrosurgical excision procedure (89.8%; 95% confidence interval, 82.1-95.2) (P = .02). Cumulative high-grade cytology incidence was higher for cryotherapy (41.9%) than loop electrosurgical excision procedure at 6 months (18.1%, P < .01) and 12 months (44.8% vs 19.4%, P < .001). Cumulative incidence of low-grade cytology or greater in cryotherapy (90.5%) did not differ from loop electrosurgical excision procedure at 6 months (80.7%, P = .08); by 12 months, cumulative incidence of low-grade cytology or greater was higher in cryotherapy (100%) than loop electrosurgical excision procedure (94.8%, P = .03). No serious adverse effects were recorded. CONCLUSION Although rates of cumulative cervical intraepithelial neoplasia grade ≥2 were lower after loop electrosurgical excision procedure than cryotherapy treatment at 6 months, both treatments appeared effective in reducing cervical intraepithelial neoplasia grade ≥2 by >70% by 12 months. The difference in cumulative cervical intraepithelial neoplasia grade ≥2 incidence between the 2 treatment methods by 12 months was not statistically significant. Relatively high cervical intraepithelial neoplasia grade ≥2 recurrence rates, indicating treatment failure, were observed in both treatment arms by 12 months. A different treatment protocol should be considered to optimally treat cervical intraepithelial neoplasia grade ≥2 in HIV-seropositive women.

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.

Cost-effectiveness of cervical cancer screening and preventative cryotherapy at an HIV treatment clinic in Kenya. COST EFFECTIVENESS AND RESOURCE ALLOCATION 2017; 15:13. [PMID: 28725164 PMCID: PMC5513032 DOI: 10.1186/s12962-017-0075-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2017] [Accepted: 07/04/2017] [Indexed: 12/30/2022] Open
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.

Abstract
Cervical cancer is one of the most common cancers among women worldwide, and approximately 85% of new diagnoses occur in less-developed regions of the world. Global efforts in cervical cancer to date have focused on primary and secondary prevention strategies of human papillomavirus vaccination and cervical cancer screening. Cervical cancer screening is effective to reduce the incidence of cervical cancer and can result in diagnosis at earlier stages, but it will take time to realize its full impact. With expansion of screening programs, there is now a greater imperative to increase access to treatment for women who have cervical cancer, particularly in earlier stages of disease, when it is still curable. Resources for multimodality treatment can be limited-or even absent-in many less-developed regions of the world and may be associated with geographic, social, and financial barriers for the patient. However, there is evidence that, in many cases, less-invasive and less-resource-intensive treatment options are still effective. To this end, the National Comprehensive Cancer Network and American Society of Clinical Oncology have published guideline adaptations for specific resource constraints, and research about more conservative approaches to the treatment of cervical cancer continues. This review focuses on potential barriers and challenges to provision of safe and effective treatment of early-stage cervical cancer in lower-resource settings, and it suggests future directions for expansion of access to cervical cancer treatment around the world.

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.

Implementation and Operational Research: Age Distribution and Determinants of Invasive Cervical Cancer in a "Screen-and-Treat" Program Integrated With HIV/AIDS Care in Zambia. J Acquir Immune Defic Syndr 2015; 70:e20-6.

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 Though cervical cancer incidence has dramatically decreased in resource rich regions due to the implementation of universal screening programs, it remains one of the most common cancers affecting women worldwide and has one of the highest mortality rates. The vast majority of cervical cancer-related deaths are among women that have never been screened. Prior to implementation of a screening program in Addis Ababa University-affiliated hospitals in Ethiopia, a survey was conducted to assess knowledge of cervical cancer etiology, risk factors, and screening, as well as attitudes and practices regarding cervical cancer screening among women's health care providers. METHODS Between February and March 2012 an anonymous, self-administered survey to assess knowledge, attitudes, and practices related to cervical cancer and its prevention was distributed to 334 health care providers at three government hospitals in Addis Ababa, Ethiopia and three Family Guidance Association clinics in Awassa, Adama, and Bahir Dar. Data were analyzed using SPSS software and chi-square test was used to test differences in knowledge, attitudes, and practices across provider type. RESULTS Overall knowledge surrounding cervical cancer was high, although awareness of etiology and risk factors was low among nurses and midwives. Providers had no experience performing cervical cancer screening on a routine basis with <40% having performed any type of cervical cancer screening. Reported barriers to performing screening were lack of training (52%) and resources (53%); however the majority (97%) of providers indicated cervical cancer screening is an essential part of women's health care. CONCLUSION There is a clear need among women's health care providers for education regarding cervical cancer etiology, risk factors and for training in low-tech, low-cost screening methods. Meeting these needs and improving the infrastructure necessary to implement appropriate screening programs is essential to reduce the burden of cervical cancer in Ethiopia.

Abstract
BACKGROUND Cervical cancer, almost all of which is caused by human papillomavirus, accounts for 12% of female cancers worldwide and is more common among HIV-infected women. Nine of 10 deaths from cervical cancer occur in low- and middle-income countries (LMICs). Simple screening methods and outpatient treatment of precursor lesions save lives but the benefit of these interventions among HIV-infected women is uncertain. OBJECTIVE We reviewed evidence of the effects of screening with visual inspection with acetic acid (VIA), and outpatient treatment for cervical precancer among HIV-infected women in LMIC. METHODS A systematic review of articles published from January 1995 through July 2013 was conducted using key terms for VIA cervical screening, cervical precancer treatment with cryotherapy or loop electrosurgical excision procedure, HIV-infected women, low-resource settings, and outcomes, including morbidity and mortality. RESULTS Of 2159 articles screened, 14 met inclusion criteria; all considered only morbidity outcomes. No articles dealt with the long-term impact of screening/treatment on cervical cancer incidence or mortality among HIV-infected women. Articles reported on performance of VIA, prevalence of cervical dysplasia, and complications and rates of recurrent dysplasia after treatment. CONCLUSIONS Dysplasia prevalence and recurrence were higher among HIV-infected compared with HIV-uninfected women but morbidity from treatment was similar. Few data exist on long-term outcomes of VIA, cryotherapy, or loop electrosurgical excision procedure interventions among HIV-infected women in LMIC; longer-term outcomes research is needed to assess the effects of VIA or other screening modalities and outpatient treatment on prevention of cervical cancer among HIV-infected women.

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.

Abstract
UNLABELLED Tanzania has the highest burden of cervical cancer in East Africa. This study aims to identify perceived barriers and facilitators that influence scale-up of regional and population-level cervical cancer screening and treatment programs in Tanzania. Convenience sampling was used to select participants for this qualitative study among 35 key informants. Twenty-eight stakeholders from public-sector health facilities, academia, government, and nongovernmental organizations completed in-depth interviews, and a seven-member municipal health management team participated in a focus group discussion. The investigation identified themes related to the infrastructure of health services for cervical cancer prevention, service delivery, political will, and sociocultural influences on screening and treatment. Decentralizing service delivery, improving access to screening and treatment, increasing the number of trained health workers, and garnering political will were perceived as key facilitators for enhancing and initiating screening and treatment services. In conclusion, participants perceived that system-level structural factors should be addressed to expand regional and population-level service delivery of screening and treatment. IMPLICATIONS FOR PRACTICE Tanzanian women have a high burden of cervical cancer. Understanding the perceived structural factors that may influence screening coverage for cervical cancer and availability of treatment may be beneficial for program scale-up. This study showed that multiple factors contribute to the challenge of cervical cancer screening and treatment in Tanzania. In addition, it highlighted systematic developments aimed at expanding services. This study is important because the themes that emerged from the results may help inform programs that plan to improve screening and treatment in Tanzania and potentially in other areas with high burdens of cervical cancer.

Abstract
BACKGROUND Very few efforts have been undertaken to scale-up low-cost approaches to cervical cancer prevention in low-resource countries. METHODS In a public sector cervical cancer prevention program in Zambia, nurses provided visual-inspection with acetic acid (VIA) and cryotherapy in clinics co-housed with HIV/AIDS programs, and referred women with complex lesions for histopathologic evaluation. Low-cost technological adaptations were deployed for improving VIA detection, facilitating expert physician opinion, and ensuring quality assurance. Key process and outcome indicators were derived by analyzing electronic medical records to evaluate program expansion efforts. FINDINGS Between 2006-2013, screening services were expanded from 2 to 12 clinics in Lusaka, the most-populous province in Zambia, through which 102,942 women were screened. The majority (71.7%) were in the target age-range of 25-49 years; 28% were HIV-positive. Out of 101,867 with evaluable data, 20,419 (20%) were VIA positive, of whom 11,508 (56.4%) were treated with cryotherapy, and 8,911 (43.6%) were referred for histopathologic evaluation. Most women (87%, 86,301 of 98,961 evaluable) received same-day services (including 5% undergoing same-visit cryotherapy and 82% screening VIA-negative). The proportion of women with cervical intraepithelial neoplasia grade 2 and worse (CIN2+) among those referred for histopathologic evaluation was 44.1% (1,735/3,938 with histopathology results). Detection rates for CIN2+ and invasive cervical cancer were 17 and 7 per 1,000 women screened, respectively. Women with HIV were more likely to screen positive, to be referred for histopathologic evaluation, and to have cervical precancer and cancer than HIV-negative women. INTERPRETATION We creatively disrupted the 'no screening' status quo prevailing in Zambia and addressed the heavy burden of cervical disease among previously unscreened women by establishing and scaling-up public-sector screening and treatment services at a population level. Key determinants for successful expansion included leveraging HIV/AIDS program investments, and context-specific information technology applications for quality assurance and filling human resource gaps.

Abstract
AIM To evaluate a cervical cancer prevention project in Guyana utilizing visual inspection with acetic acid (VIA) and immediate cryotherapy in a single-visit approach; and to identify lessons learned to inform the improvement of cervical cancer prevention programs in Guyana and other low-resource settings. METHODS Service records from January 2009 to June 2012 were analyzed for 18 cervical cancer prevention sites across Guyana. Records included women's HIV status, data on visual inspection with acetic acid screening and treatment status for women's initial and 1-year follow-up screenings, provider training and retention. A process evaluation was conducted in 2011 to identify programmatic strengths and interventions for integration, scale-up and sustainability. RESULTS During the 42-month interval, 21,597 new screenings were performed, reaching 95% of HIV(+) women enrolled in care and 17% of women aged 25-49 years in Guyana. The VIA(+) rate was 13% (n = 2806); 85% of women eligible for cryotherapy received immediate treatment. Half of VIA(+) women treated with cryotherapy or loop electrosurgical excision procedure returned for a 1-year follow-up screening (n = 1027); 95% were VIA(-) at the second screening. Non-physician providers were more likely to continue offering services than physicians. Most programmatic challenges were related to systemic rather than technical/clinical issues. CONCLUSION The single-visit approach-based program is feasible, effective, and when scaled up, likely to have an impact on overall incidence of cervical cancer. Services can be shifted to non-physicians for scale-up of high-quality cervical cancer prevention services nationally. To ensure sustainability and expansion, support structures should be prioritized.

Abstract
Although there is a growing literature on the clinical performance of visual inspection with acetic acid in HIV-infected women, to the best of our knowledge, none have studied visual inspection with acetic acid enhanced by digital cervicography. We estimated clinical performance of cervicography and cytology to detect cervical intraepithelial neoplasia grade 2 or worse. Sensitivity and specificity of cervicography were 84% [95% confidence interval (CI): 72 to 91) and 58% (95% CI: 52 to 64). At the high-grade squamous intraepithelial lesion or worse cutoff for cytology, sensitivity and specificity were 61% (95% CI: 48 to 72) and 58% (95% CI: 52 to 64). In our study, cervicography seems to be as good as cytology in HIV-infected women.

Abstract
It is estimated that Haiti has the highest incidence of cervical cancer in the Western Hemisphere. There are currently no sustainable and affordable cervical cancer screening programs in Haiti. The current status of screening services and knowledge of health care professionals was assessed through a Knowledge, Attitudes, and Practices survey on cervical cancer screening and prevention. It was distributed to Project Medishare for Haiti health care workers (n = 27) in the Central Plateau. The majority (22/27) of participants stated pre-cancerous cells could be detected through screening, however, only four had ever performed a pap smear. All of the participants felt a screening program should be started in their area. Our data establishes that knowledge is fairly lacking among healthcare workers and there is an opportunity to train them in simple, cost effective "screen-and-treat" programs that could have a great impact on the overall health of the population.

BMC Womens Health 2014; 14:120. [PMID: 25271025 PMCID: PMC4190378 DOI: 10.1186/1472-6874-14-120] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2014] [Accepted: 08/28/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND While the lifetime risk of developing cervical cancer (CaCx) and acquiring HIV is high for women in Tanzania, most women have not tested for HIV in the past year and most have never been screened for CaCx. Good management of both diseases, which have a synergistic relationship, requires integrated screening, prevention, and treatment services. The aim of this analysis is to assess the acceptability, feasibility and effectiveness of integrating HIV testing into CaCx prevention services in Tanzania, so as to inform scale-up strategies. METHODS We analysed 2010-2013 service delivery data from 21 government health facilities in four regions of the country, to examine integration of HIV testing within newly introduced CaCx screening and treatment services, located in the reproductive and child health (RCH) section of the facility. Analysis included the proportion of clients offered and accepting the HIV test, reasons why testing was not offered or was declined, and HIV status of CaCx screening clients. RESULTS A total of 24,966 women were screened for CaCx; of these, approximately one-quarter (26%) were referred in from HIV care and treatment clinics. Among the women of unknown HIV status (n = 18,539), 60% were offered an HIV test. The proportion of women offered an HIV test varied over time, but showed a trend of decline as the program expanded. Unavailability of HIV test kits at the facility was the most common reason for a CaCx screening client not to be offered an HIV test (71% of 6,321 cases). Almost all women offered (94%) accepted testing, and 5% of those tested (582 women) learned for the first time that they were HIV-positive. CONCLUSION Integrating HIV testing into CaCx screening services was highly acceptable to clients and was an effective means of reaching HIV-positive women who did not know their status; effectiveness was limited, however, by shortages of HIV test kits at facilities. Integration of HIV testing into CaCx screening services should be prioritized in HIV-endemic settings, but more work is needed to eliminate logistical barriers. The coverage of CaCx screening among HIV care and treatment-enrolled women in Tanzania may be low and should be examined.

Most women diagnosed with cervical cancer by a visual screening program in Tanzania completed treatment: evidence from a retrospective cohort study. BMC Public Health 2014; 14:910. [PMID: 25187329 PMCID: PMC4162936 DOI: 10.1186/1471-2458-14-910] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2013] [Accepted: 07/29/2014] [Indexed: 12/01/2022] Open
Abstract
Background Visual inspection with acetic acid (VIA) to identify and treat pre-cancerous lesions is effective for cervical cancer prevention. Screening programs also facilitate screening and diagnosis of invasive cancers that must be referred for radiation therapy or chemotherapy. This study compared characteristics of women diagnosed with invasive cervical cancer by a VIA screening program who did and did not follow up for treatment and who did and did not complete treatment at the Ocean Road Cancer Institute (ORCI), Dar es Salaam, Tanzania. Methods We conducted a retrospective cohort study of ORCI screening referrals from the period November 2002 to June 2011. Women referred for treatment of invasive disease (n = 980) were identified from an existing database of all women attending the screening clinic during this period (n = 20,131) and matched to a dataset of all cervical cancer patients attending ORCI in this period (n = 8,240). Treatment information was abstracted from patient records of women who followed up. Records of a random sample (n = 333) of unscreened patients were reviewed for disease stage. Results Of the 980 women referred women, 829 (84.6%) sought treatment. Most of those women (82.8%) completed their prescribed radiation. Lower disease stage, having a skilled occupation, residence in Dar es Salaam, and younger age were independently associated with loss to follow-up. Higher disease stage, residence in Dar es Salaam, older age, and later year of first treatment appointment were independently associated with incomplete treatment among those who followed up. Significantly more screened women had stage 1 disease (14.0%) than unscreened women (7.8%). Conclusions Most women referred from the screening clinic completed treatment for their cancer at ORCI. Some of those lost to follow-up may have sought treatment elsewhere. In most cases, the screening clinic appears to facilitate diagnosis and treatment, rather than screening, for women with invasive cervical cancer.

Is screen-and-treat approach suited for screening and management of precancerous cervical lesions in Sub-Saharan Africa? Prev Med 2014; 65:138-40. [PMID: 24879892 DOI: 10.1016/j.ypmed.2014.05.014] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/28/2014] [Revised: 05/08/2014] [Accepted: 05/19/2014] [Indexed: 01/17/2023]
Abstract
The World Health Organization guidelines for screening and management of cervical precancerous lesions updated in 2013 made an emphasis on the use of the 'screen-and-treat' approach for cervical cancer prevention. In order to facilitate scaling-up in low income settings, most of these screen-and-treat strategies do not involve confirmatory biopsy. This yields a certain rate of overtreatment. In other words, a majority of people undergoing screen-and-treat intervention who are treated does not necessarily benefit from the treatment. Therefore, the issue of potential short term and long term complications of the recommended treatment procedures (cryotherapy and Loop Electrosurgical Excision Procedure) arises. This question has seldom been studied in resource poor countries, particularly in Sub-Saharan Africa where Human Immunodeficiency Virus infection is rampant in an epidemic fashion and where the procreative capacities are socially rewarding for women. We draw the attention of the scientific community and policy makers to the fact that the lack of evidence supporting the safety of these treatment procedures in African populations may have an impact on the acceptability of these strategies and therefore on the effectiveness of screening programs.

Infrastructure requirements for human papillomavirus vaccination and cervical cancer screening in sub-Saharan Africa. Vaccine 2014; 31 Suppl 5:F47-52. [PMID: 24331747 DOI: 10.1016/j.vaccine.2012.06.066] [Citation(s) in RCA: 63] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2011] [Revised: 06/14/2012] [Accepted: 06/18/2012] [Indexed: 12/11/2022]
Abstract
The availability of both human papillomavirus (HPV) vaccination and alternative screening tests has greatly improved the prospects of cervical cancer prevention in sub-Saharan African (SSA) countries. The inclusion of HPV vaccine in the portfolio of new vaccines offered by the Gobal Alliance for Vaccines and Immunization (GAVI) to GAVI-eligible countries has vastly improved the chances of introducing HPV vaccination. Further investments to improve vaccine storage, distribution and delivery infrastructure and human resources of the Extended Programme of Immunization will substantially contribute to the faster introduction of HPV vaccination in SSA countries through both school- and campaign-based approaches. Alternative methods to cytology for the prevention of cervical cancer through the early detection and treatment of cervical cancer precursors have been extensively evaluated in the past 15 years, in Africa as well as in other low-resource settings. Visual inspection with 3-5% dilute acetic acid (VIA) and HPV testing are the two alternative screening methods that have been most studied, in both cross-sectional and randomised clinical trials. VIA is particularly suitable to low-resource settings; however, its efficacy in reducing cervical cancer is likely to be significantly lower than HPV testing. The introduction of VIA screening programmes will help develop the infrastructure that will, in turn, facilitate the introduction of affordable HPV testing in future. Links with the existing HIV/AIDS control programmes is another strategy to improve the infrastructure and screening services in SSA. Infrastructural requirements for an integrated approach aiming to vaccinate single-year cohorts of girls in the 9-13 years age-range and to screen women over 30 years of age using VIA or affordable rapid HPV tests are outlined in this manuscript. This article forms part of a regional report entitled "Comprehensive Control of HPV Infections and Related Diseases in the Sub-Saharan Africa Region" Vaccine Volume 31, Supplement 5, 2013. Updates of the progress in the field are presented in a separate monograph entitled "Comprehensive Control of HPV Infections and Related Diseases" Vaccine Volume 30, Supplement 5, 2012.

Abstract
Background Increasingly evidence is emerging from south East Asia, southern and east Africa on the burden of default to follow up care after a positive cervical cancer screening/diagnosis, which impacts negatively on cervical cancer prevention and control. Unfortunately little or no information exists on the subject in the West Africa sub region. This study was designed to determine the proportion of and predictors and reasons for default from follow up care after positive cervical cancer screen. Method Women who screen positive at community cervical cancer screening using direct visual inspection were followed up to determine the proportion of default and associated factors. Multivariate logistic regression was used to determine independent predictors of default. Results One hundred and eight (16.1%) women who screened positive to direct visual inspection out of 673 were enrolled into the study. Fifty one (47.2%) out of the 108 women that screened positive defaulted from follow-up appointment. Women who were poorly educated (OR: 3.1, CI: 2.0 – 5.2), or lived more than 10 km from the clinic (OR: 2.0, CI: 1.0 – 4.1), or never screened for cervical cancer before (OR: 3.5, CI:3:1–8.4) were more likely to default from follow-up after screening positive for precancerous lesion of cervix . The main reasons for default were cost of transportation (48.6%) and time constraints (25.7%). Conclusion The rate of default was high (47.2%) as a result of unaffordable transportation cost and limited time to keep the scheduled appointment. A change from the present strategy that involves multiple visits to a “see and treat” strategy in which both testing and treatment are performed at a single visit is recommended.

Performance of visual inspection with acetic acid and human papillomavirus testing for detection of high-grade cervical lesions in HIV positive and HIV negative Tanzanian women.

Abstract
The aim of this cross sectional study was to assess type distribution of human papillomavirus (HPV) among HIV positive and HIV negative women who underwent cervical cancer screening, and to examine the ability of visual inspection with acetic acid (VIA), the standard detection method in Tanzania, and HPV-testing to detect cytologically diagnosed high grade lesions or cancer (HSIL+). Women from different areas in Tanzania were invited by public announcement to cervical cancer screening organized by Ocean Road Cancer Institute (Dar-es-Salaam). A total of 3,767 women were enrolled. Women underwent gynecological examination with collection of cervical cells for conventional cytological examination, and swab for HPV-DNA detection (Hybrid-Capture2) and genotyping (LiPAv2 test). Subsequently VIA was performed. The participants were also tested for HIV. HPV16, HPV52 and HPV18 were the three most common HR HPV types among women with HSIL+ cytology with prevalences of 42.9, 35.7 and 28.6%, respectively, in HIV positive women which was higher than among HIV negative women (30.2, 21.9 and 16.7%). A total of 4.5% of the women were VIA positive, and VIA showed a low sensitivity compared to HPV-testing for detection of HSIL+. The sensitivity of VIA varied with staff VIA experience, HIV status and age. Vaccines including HPV16, HPV52 and HPV18 will likely reduce the number of HSIL+ cases independently of HIV status. The frequency of HSIL+ was high among HIV positive women, emphasizing the importance of establishing a screening program which also reaches HIV positive women. Our results highlight the importance of continuous training of staff performing VIA, and also point to the need for other screening methods such as HPV-testing at low cost.

Abstract
Background In the absence of stand-alone infrastructures for delivering cervical cancer screening services, efforts are underway in sub-Saharan Africa to dovetail screening with ongoing vertical health initiatives like HIV/AIDS care programs. Yet, evidence demonstrating the utilization of cervical cancer prevention services in such integrated programs by women of the general population is lacking. Methods We analyzed program operations data from the Cervical Cancer Prevention Program in Zambia (CCPPZ), the largest public sector programs of its kind in sub-Saharan Africa. We evaluated patterns of utilization of screening services by HIV serostatus, examined contemporaneous trends in screening outcomes, and used multivariable modeling to identify factors associated with screening test positivity. Results Between January 2006 and April 2011, CCPPZ services were utilized by 56,247 women who underwent cervical cancer screening with visual inspection with acetic acid (VIA), aided by digital cervicography. The proportion of women accessing these services who were HIV-seropositive declined from 54% to 23% between 2006–2010, which coincided with increasing proportions of HIV-seronegative women (from 22% to 38%) and women whose HIV serostatus was unknown (from 24% to 39%) (all p-for trend<0.001). The rates of VIA screening positivity declined from 47% to 17% during the same period (p-for trend <0.001), and this decline was consistent across all HIV serostatus categories. After adjusting for demographic and sexual/reproductive factors, HIV-seropositive women were more than twice as likely (Odds ratio 2.62, 95% CI 2.49, 2.76) to screen VIA-positive than HIV-seronegative women. Conclusions This is the first ‘real world’ demonstration in a public sector implementation program in a sub-Saharan African setting that with successful program scale-up efforts, nurse-led cervical cancer screening programs targeting women with HIV can expand and serve all women, regardless of HIV serostatus. Screening program performance can improve with adequate emphasis on training, quality control, and telemedicine-support for nurse-providers in clinical decision making.

Abstract
OBJECTIVE To determine the prevalence of invasive cervical cancer (ICC) and assess access to, and outcomes of, treatment for ICC among HIV-infected women in Kisumu, Kenya. METHODS We performed a retrospective chart review to identify women diagnosed with ICC between October 2007 and June 2012, and to examine the impact of a change in the referral protocol. Prior to June 2009, all women with ICC were referred to a regional hospital. After this date, women with stage IA1 disease were offered treatment with loop electrosurgical excision procedure (LEEP) in-clinic. RESULTS Of 4308 women screened, 58 (1.3%) were diagnosed with ICC. The mean age at diagnosis was 34years (range, 22-50years). Fifty-four (93.1%) women had stage IA1 disease, of whom 36 (66.7%) underwent LEEP, 7 (12.9%) had a total abdominal hysterectomy, and 11 (20.4%) had unknown or no treatment. At 6, 12, and 24months after LEEP, 8.0% (2/25), 25.0% (6/24), and 41.2% (7/17) of women had a recurrence of cervical intraepithelial neoplasia 2 or worse, respectively. CONCLUSION Most HIV-positive women diagnosed with ICC through screening had early-stage disease. The introduction of LEEP in-clinic increased access to treatment; however, recurrence was high, indicating the need for continued surveillance.

Abstract
Background HIV-infected women are at a higher risk of cervical intraepithelial neoplasia (CIN) and cancer than women in the general population, partly due to a high prevalence of persistent human papillomavirus (HPV) infection. The aim of the study was to assess the burden of HPV infection, cervical abnormalities, and cervical cancer among a cohort of HIV-infected women as part of a routine screening in an urban overpopulated slum setting in Mumbai, India. Methods From May 2010 to October 2010, Médecins Sans Frontières and Tata Memorial Hospital Mumbai offered routine annual Pap smears and HPV DNA testing of women attending an antiretroviral therapy (ART) clinic and a 12-month follow-up. Women with abnormal test results were offered cervical biopsy and treatment, including treatment for sexually transmitted infections (STIs). Results Ninety-five women were screened. Median age was 38 years (IQR: 33–41); median nadir CD4-count 143 cells/μL (IQR: 79–270); and median time on ART 23 months (IQR:10–41). HPV DNA was detected in 30/94 women (32%), and 18/94 (19%) showed either low-grade or high-grade squamous intraepithelial lesions (LSIL/HSIL) on Pap smear. Overall, >50% had cervical inflammatory reactions including STIs. Of the 43 women with a cervical biopsy, eight (8.4%) had CIN-1, five (5.3%) CIN-2, and two (2.1%) carcinoma in situ. All but one had HPV DNA detected (risk ratio: 11, 95% confidence interval: 3.3–34). By October 2011, 56 women had completed the 12-month follow-up and had been rescreened. No new cases of HPV infection/LSIL/HSIL were detected. Conclusion The high prevalence of HPV infection, STIs, and cervical lesions among women attending an ART clinic demonstrates a need for routine screening. Simple, one-stop screening strategies are needed. The optimal screening interval, especially when resources are limited, needs to be determined.

Abstract
BACKGROUND Human immunodeficiency virus positive (HIV+) women have a higher risk of developing invasive cervical cancer compared with uninfected women. This study aims to document programmatic experience of integrating cervical cancer screening using Visual Inspection and Acetic Acid (VIA) into HIV care as well as to describe patients' characteristics associated with positive VIA findings amongst HIV+ women. MATERIALS AND METHODS A cross-sectional study analysed routine service data collected at the antiretroviral therapy (ART) and cervical cancer screening services. Our program integrated screening for cervical cancer using VIA technique to HIV care and treatment services through a combination of stakeholder engagement, capacity building for health workers, creating a bi-directional referral between HIV and reproductive health (RH) services and provider initiated counselling and screening for cervical cancer. Information on patients' baseline and clinical characteristics were captured using an electronic medical records system and then exported to Statistical Package for the Social Sciences (SPSS). Logistic regression model was used to estimate factors that influence VIA results. RESULTS A total of 834 HIV+ women were offered VIA screening between April 2010 and April 2011, and 805 (96.5%) accepted it. Complete data was available for 802 (96.2%) women. The mean age at screening and first sexual contact were 32.0 (SD 6.6) and 18.8 (SD 3.5) years, respectively. VIA was positive in 52 (6.5%) women while 199 (24.8%) had a sexually transmitted infection (STI). Of the 199 who had a STI, eight (4.0%) had genital ulcer syndrome, 30 (15.1%) had lower abdominal pain syndrome and 161 (80.9%) had vaginal discharge syndrome. Presence of lower abdominal pain syndrome was found to be a significant predictor of a positive VIA result (P = 0.001). Women with lower abdominal pain syndrome appeared to be more likely (OR 47.9, 95% CI: 4.8-480.4, P = 0.001) to have a positive VIA result. CONCLUSION The high burden of both HIV and cervical cancer in developing countries makes it a necessity for integrating services that offer early detection and treatment for both diseases. The findings from our study suggest that integrating VIA screening into the package of care offered to HIV+ women is feasible and acceptable.

Abstract
Context.—Cervical cancer remains the most common malignancy in women living in low- and middle-income countries, despite the decline of the disease in countries where cervical cytology screening programs have been implemented.
Objectives.—To review the current incidence of cervical cancer in low-resource countries, the availability and types of screening programs, and the treatment options.
Data Sources.—Literature review through PubMed, Internet search, and personal communication.
Conclusions.—Although data are incomplete, available figures confirm that the rate of cervical cancer deaths and the availability of cervical cancer screening programs are inversely proportional and vary, in general, by the wealth of the nation. Despite the success of cervical cytology screening, many major health care organizations have abandoned screening by cytology in favor of direct visualization methods with immediate treatment of lesions by cryotherapy provided by trained, nonmedical personnel.

Bolstering the Evidence Base for Integrating Abortion and HIV Care: A Literature Review. AIDS Res Treat 2012; 2012:802389.

Abstract
HIV-positive women have abortions at similar rates to their HIV-negative counterparts, yet little is known about clinical outcomes of abortion for HIV-positive women or the best practices for abortion provision. To fill that gap, we conducted a literature review of clinical outcomes of surgical and medication abortion among HIV-positive women. We identified three studies on clinical outcomes of surgical abortion among HIV-positive women; none showed significant differences in infectious complications by HIV status. A review of seven articles on similar gynecological procedures found no differences in complications by HIV status. No studies evaluated medication abortion among HIV-positive women. However, we did find that previously expressed concerns regarding blood loss and vomiting related to medication abortion for HIV-positive women are unwarranted based on our review of data showing that significant blood loss and vomiting are rare and short lived among women. We conclude that although there is limited research that addresses clinical outcomes of abortion for HIV-positive women, existing data suggest that medication and surgical abortion are safe and appropriate. Sexual and reproductive health and HIV integration efforts must include both options to prevent maternal mortality and morbidity and to ensure that HIV-positive women and women at risk of HIV can make informed reproductive decisions.

Abstract
BACKGROUND In Zambia, a country with a generalized HIV epidemic, age-adjusted cervical cancer incidence is among the highest worldwide. In 2006, the University of Alabama at Birmingham-Center for Infectious Disease Research in Zambia and the Zambian Ministry of Health launched a visual inspection with acetic acid (VIA) -based "see and treat" cervical cancer prevention program in Lusaka. All services were integrated within existing government-operated primary health care facilities. OBJECTIVE Study aims were to (i) identify women's motivations for cervical screening, (ii) document women's experiences with screening and (iii) describe the potentially reciprocal influences between women undergoing cervical screening and their social networks. DESIGN AND METHODS Focus group discussions (FGD) and in-depth interviews (IDI) were conducted with women who accepted screening and with care providers. Low-level content analysis was performed to identify themes evoked by participants. Between September 2009 and July 2010, 60 women and 21 care providers participated in 8 FGD and 10 IDI. RESULTS Women presented for screening with varying needs and expectations. A majority discussed their screening decisions and experiences with members of their social networks. Key reinforcing factors and obstacles to VIA screening were identified. CONCLUSIONS Interventions are needed to gain support for the screening process from influential family members and peers.

Abstract
Background Cervical cancer screening is not yet standard of care of women attending HIV care clinics in Africa and presents operational challenges that need to be addressed. Methods A cervical cancer screening program based on visual inspection methods was conducted in clinics providing antiretroviral treatment (ART) in Abidjan, Côte d'Ivoire. An itinerant team of midwives was in charge of proposing cervical cancer screening to all HIV-positive women enrolled in ART clinics as well as to HIV-negative women who were attending the Abidjan national blood donor clinic. Positively screened women were systematically referred to a colposcopic examination. A phone-based tracking procedure was implemented to reach positively screened women who did not attend the medical consultation. The association between HIV status and cervical cancer screening outcomes was estimated using a multivariate logistic model. Results The frequency of positive visual inspection was 9.0% (95% CI 8.0-10.0) in the 2,998 HIV-positive women and 3.9% (95% CI 2.7-5.1) in the 1,047 HIV-negative ones (p < 10-4). In multivariate analysis, HIV infection was associated with a higher risk of positive visual inspection [OR = 2.28 (95% CI 1.61-3.23)] as well as more extensive lesions involving the endocervical canal [OR = 2.42 (95% CI 1.15-5.08)]. The use of a phone-based tracking procedure enabled a significant reduction of women not attending medical consultation after initial positive screening from 36.5% to 19.8% (p < 10-4). Conclusion The higher frequency of positive visual inspection among HIV-positive women supports the need to extend cervical cancer screening program to all HIV clinics in West Africa. Women loss to follow-up after being positively screened is a major concern in cervical screening programs but yet, partly amenable to a phone tracking procedure.

Abstract
Invasive cervical cancer is the second most common cancer among women worldwide, with approximately 85% of the disease burden occurring in developing countries. To date, there have been few systematic efforts to document African women's conceptualization of cervical cancer after participation in a visual inspection with acetic acid (VIA)-based "see and treat" cervical cancer prevention program. In this study, conducted between September, 2009-July, 2010, focus groups and in-depth interviews were conducted with 60 women who had recently undergone cervical cancer screening at a government-operated primary health care clinic in Lusaka, Zambia. Interviewers elicited participants' causal representations of cervical cancer, associated physical signs and symptoms, perceived physical and psychological effects, and social norms regarding the disease. The lay model of illness causation portrayed by participants after recent exposure to program promotion messages departed in several ways from causal models described in other parts of the world. However, causal conceptualizations included both lay and biomedical elements, suggesting a possible shift from a purely traditional causal model to one that incorporates both traditional concepts and recently promoted biomedical concepts. Most, but not all, women still equated cervical cancer with death, and perceived it to be a highly stigmatized disease in Zambia because of its anatomic location, dire natural course, connections to socially-condemned behaviors, and association with HIV/AIDS. No substantive differences of disease conceptualization existed according to HIV serostatus, though HIV positive women acknowledged that their immune status makes them more aware of their health and more likely to seek medical attention. Further attention should be dedicated to the processes by which women incorporate new knowledge into their representations of cervical cancer.

Abstract
The annual worldwide burden of the preventable disease cervical cancer is more than 530,000 new cases and 275,000 deaths, with the majority occurring in low- and middle-income countries (LMIC), where cervical cancer screening and early treatment are uncommon. Widely used in high-income countries, Pap smear (cytology based) screening is expensive and challenging for implementation in LMICs, where lower-cost, effective alternatives such as visual inspection with acetic acid (VIA) and rapid human papillomavirus (HPV)-based screening tests offer promise for scaling up prevention services. Integrating HPV screening with VIA in "screen-and-treat-or-refer" programs offers the dual benefits of HPV screening to maximize detection and using VIA to triage for advanced lesions/cancer, as well as a pelvic exam to address other gynecologic issues. A major issue in LMICs is coinfection with human immunodeficiency virus (HIV) and HPV, which further increases the risk for cervical cancer and marks a population with perhaps the greatest need of cervical cancer prevention. Public-private partnerships to enhance the availability of cervical cancer prevention services within HIV/AIDS care delivery platforms through initiatives such as Pink Ribbon Red Ribbon present an historic opportunity to expand cervical cancer screening in LMICs.
