RESUMO
BACKGROUND: The proportion of older people living with HIV (PLWH) has increased. Non-communicable diseases occur earlier in PLWH than in the general population. OBJECTIVE: The goal of this study was to estimate the prevalence of comorbidities in PLWH and cancer in a tertiary referral center in Mexico City. MATERIAL AND METHODS: In this retrospective study, we included PLWH > 40 years with a history of cancer, coming to Instituto Nacional de Cancerologia from 2010 through 2019. All patients needed to be on antiretrovirals for at least six months. Data collected included cancer type, comorbidities, frequency of polypharmacy, FRAX score and 10-year cardiovascular risk. Patients were evaluated for depression with the Beck Inventory Depression-II Scale. Variables associated to multimorbidity (2 or more comorbidities) were evaluated. RESULTS: Of 125 patients, 69% had at least one comorbidity; 32% had ≥ 2. Common comorbidities were dyslipidemia (54%), hypertension (19%), obesity (14%) and Diabetes (12%). In patients ≥ 50 years, 29 (62%) already undergone a densitometry and 9 (31%) had osteoporosis; 56 depression questionnaires were used: 30% had mild-to-severe depression. Being ≥ 50 years was associated with multimorbidity (aOR 2.57 (1.18-5.58), p = 0.017). CONCLUSIONS: A high prevalence of multimorbidity and poor screening of bone disease and mental health is reported in patients with PLWH and cancer. A holistic approach to the PLWH in the Infectious Diseases consultation is needed to improve the detection and management of non-communicable diseases, to go beyond viral suppression and towards an improved quality of life.
INTRODUCCIÓN: La proporción de personas mayores que viven con VIH (PVVIH) va en aumento, y las enfermedades no transmisibles ocurren antes en PVVIH comparado con la población general. OBJETIVO: El objetivo de este estudio fue estimar la prevalencia de las comorbilidades en PVVIH con cáncer de un centro de tercer nivel de la Ciudad de México. MÉTODOS: Este estudio retrospectivo incluyó todas las PVVIH > 40 años con cáncer, que acudieron al Instituto Nacional de Cancerología entre 2010 y 2019). Se incluyeron datos sobre el tipo de cáncer, comorbilidades y polifarmacia. Se calcularon la puntuación FRAX, el riesgo cardiovascular a 10 años, y se aplicó un cuestionario para evaluar depresión (Beck Inventory Depression-II Scale). RESULTADOS: De 125 pacientes, 69% tenía al menos una comorbilidad; 32% tenía ≥ 2. Las comorbilidades más comunes fueron dislipidemia (54%), hipertensión (19%), obesidad (14%) y diabetes (12%). En pacientes ≥ 50 años, 29% tenía una densitometría osea; 31% tenía osteoporosis. Se aplicaron 56 cuestionarios: 30% tenía algún grado de depresión. Tener ≥ 50 años se asoció con multimorbilidad (aOR 2.57, 1.18-5.58), p = 0.017. CONCLUSIONES: Se reporta una alta prevalencia de multimorbilidad en PVVIH y cancer, con pobre escrutinio de enfermedad ósea y salud mental. Se requiere un enfoque holístico para las PVVIH en la consulta de infectología, para mejorar el manejo de las enfermedades no transmisibles, yendo más alla de la supresión virológica.

Cervical cancer screening and treatment of screen positives is an important and effective strategy to reduce cervical cancer morbidity and mortality. In order to have an accurate cervical cancer screening and evaluation of positives, the entire Squamocolumnar Junction (SCJ) must be visible. Throughout the life course, the position of the SCJ changes and affects its visibility. SCJ visibility was analyzed among participants screened at the League Against Cancer Clinic in Lima, Peru. Of the 4247 participants screened, the SCJ was fully visible in 49.7% of participants, partially visible in 23.1%, and not visible in 27.2%. Visibility decreased with age, and by age 45 years old, the SCJ was not fully visible in over 50% of participants. Our results show that a high percentage of participants at ages still recommended for screening do not have totally visible SCJ, and we may need to reconsider the upper age limit for screening and find new strategies for evaluation of those with a positive screening test and non-visible SCJ.

Introduction: International guidelines recommend hospital care for patients with severe Coronavirus disease (COVID-19), but fragile health care systems struggle to cope with high number of admissions, placing patients at risk of receiving substandard care. We describe an outpatient ambulatory surveillance and treatment strategy (OPAT) for health care workers (HCWs) with severe COVID-19 during low hospital bed availability periods in Mexico City. Methods: In this observational, descriptive, retrospective study, we included HCWs with severe disease for whom there were no hospital beds available at the time of evaluation. We provided daily assessments by infectious disease specialists, daily ambulatory steroid, oral thromboprophylaxis and domiciliary low-dose oxygen. We recorded the number of patients who recovered, were hospitalized or died on follow-up. Results: From 18 March 2020 to 16 July 2021, 1739 HCWs attended our service. A total of 540 were diagnosed with COVID-19. Seventy-four had severe COVID-19 and needed hospitalization. Immediate hospitalization was not possible in 56 patients who were sent to the OPAT and included in our study. Twenty-four patients subsequently required hospitalization and 32 recovered as outpatients. Conclusions: We describe a feasible and safe outpatient management strategy for HCWs with severe COVID-19 in a low-resource setting.
RESUMO
Background: The COVID-19 pandemic has altered the usual dynamics of consultation and presentation for acute appendicitis (AA). The aim of this study was to evaluate the impact of the pandemic and restrictive measures on the cases of AA. Subjects and Methods: A retrospective study of patients diagnosed with AA between December 2019 and July 2020 was conducted. Patients were classified into two groups; one that underwent treatment in the 16 weeks before the implementation of lockdown in Argentina (Group 1) and another that underwent treatment in the 16 weeks after (Group 2). Demographic, clinical and surgical variables were evaluated. Results: Overall, 91 patients underwent surgery, 61 and 30 patients in each group, showing a 51% drop in the incidence. The second group delayed seeking medical care longer (mean 46 h vs. 27 h, P < 0.05), had a higher rate of perforated appendicitis (30% vs. 11%, P < 0.05) and a higher rate of complicated appendicitis (56.6% vs. 18%, P < 0.01). These results were associated with a longer operative time (43.7 ± 15.5 min vs. 36.1 ± 11.1 min, P < 0.05) and a longer mean length of hospital stay (1.9 days vs. 1.4 days, P < 0.01); however, no increase in the quantity and severity of post-operative complications was observed. Conclusion: COVID-19 pandemic and restrictive social measures led to fewer consultations for abdominal pain, resulting in a lower number of AA diagnosed. In addition, a longer delay in seeking medical care was observed, leading to more advanced disease, longer operative time and length of hospital stay.

RESUMO
Cervical cancer mortality is high among Peruvian women of reproductive age. Understanding barriers and facilitators of cervical cancer screening and treatment could facilitate development of contextually-relevant interventions to reduce cervical cancer incidence and mortality. From April to October 2019, we conducted a cross-sectional survey with 22 medical personnel and administrative staff from Liga Contra el Cancer, in Lima, Peru. The survey included structured and open-ended questions about participants' roles in cervical cancer prevention and treatment, perceptions of women's barriers and facilitators for getting screened and/or treated for cervical cancer, as well as attitudes towards adopting new cervical cancer interventions. For structured questions, the frequency of responses for each question was calculated. For responses to open-ended questions, content analysis was used to summarize common themes. Our data suggest that the relative importance and nature of barriers that Peruvian women face are different for cervical cancer screening compared to treatment. In particular, participants mentioned financial concerns as the primary barrier to treatment and a lack of knowledge or awareness of human papillomavirus and/or cervical cancer as the primary barrier to screening uptake among women. Participants reported high willingness to adopt new interventions or strategies related to cervical cancer. Building greater awareness about benefits of cervical cancer screening among women, and reducing financial and geographic barriers to treatment may help improve screening rates, decrease late-stage diagnosis and reduce mortality in women who have a pre-cancer diagnosis, respectively. Further studies are needed to generalize study findings to settings other than Lima, Peru.
RESUMO
PURPOSE: This study aims to assess the detection of cervical intraepithelial lesions grades 2 and 3 (CIN2-3) at 1 year after treatment with thermal ablation among human papillomavirus (HPV)-positive and visual inspection with acetic acid (VIA)-positive women. METHODS: All women screened and triaged for cervical cancer at four government health facilities in Honduras who were eligible for ablative treatment were enrolled and treated with thermal ablation. Women with confirmed CIN2-3 and a subset of women with CIN1/normal diagnoses at baseline were evaluated at 12 months. Follow-up procedures included HPV testing (careHPV), VIA, directed biopsy (if VIA-positive), and Papanicolaou test (if HPV positive, VIA negative). Outcomes at 1 year included histologic or cytologic assessment of CIN lesions among those with any abnormal test. RESULTS: Among the 319 women treated with thermal ablation, baseline histologic diagnoses were available for 317. Two (0.6%) had invasive cancer, 36 (11.4%) had CIN3, 40 (12.6%) had CIN2, and 239 (75.4%) had CIN1/normal histology. Among the 127 women eligible for follow-up, 118 (92.9%) completed all study procedures at 1 year. Overall, 98 (83.1%) had no evidence of CIN2-3 or persistent low-grade infection, 13 (11.2%) had CIN1/atypical squamous cells of undetermined significance, six (5.1%) had CIN2/high-grade squamous intraepithelial lesion, and 1 (0.8%) had a persistent CIN3. No adverse events associated with thermal ablation at 1 year were registered. CONCLUSION: A high proportion of women had no evidence of CIN2-3 at 1 year after thermal ablation treatment. Thermal ablation is an alternative to cryotherapy that may facilitate greater treatment coverage and prevent unnecessary deaths from cervical cancer.

Abstract Objective: To evaluate age patterns in human papillomavirus (HPV) prevalence and visual inspection with acetic acid (VIA) positivity among women participating in cervical cancer screening in Honduras. Materials and methods: Data on the HPV status (careHPV) and subsequent VIA in HPV-positive women were retrieved from three provinces within the Public Health Sector. Results: Between 2015 and 2018, 60 883 women aged 15-85 years were screened. HPV was detected in 15%, with variation by age, peaking at 20-24 years (27.8%) decreasing to 16% at 30-49 years. Differences in point age-specific HPV prevalence were observed between provinces, but with similar age pattern. VIA was positive in 24.5% of the women aged 30-44 years. Conclusions: The age pattern of the HPV prevalence supports starting HPV testing at age 30+. The low positivity of VIA in ages close to menopause suggest underdetection of cervical lesions in this age group.
Resumen Objetivo: Evaluar la prevalencia del virus del papiloma humano (VPH) y la positividad a la inspección visual con ácido acético (IVA) de cáncer cervicouterico, según edad en mujeres tamizadas en Honduras. Material y métodos: Se extrajo información sobre la prueba de VPH (careHPV) y de IVA en tres provincias en el ámbito de la Atención Pública en Salud. Resultados: Durante 2015-2018, 60 883 mujeres de 15-85 años fueron tamizadas, 15% fueron VPH positivas con valores máximos en mujeres de 20-24 años (27.8%), con una disminución a 16% entre 30-49 años. Se observaron diferencias mínimas entre provincias, con un patrón de edad similar. La IVA fue positiva en 24.5% en mujeres de 30-44 años, con una posterior disminución. Conclusiones: La curva de prevalencia del VPH respalda el tamizar con VPH a los 30+ años. La baja positividad de la IVA en edades cercanas a la menopausia sugiere una subdetección de lesiones cervicales en este grupo.

BACKGROUND: In Nicaragua, cervical cancer is the leading cause of cancer death among women. Human papillomavirus (HPV) testing, primarily using self-sampling, was introduced between 2014 and 2018 in three provinces. We analyzed data from the HPV screening program with the goal of describing key characteristics including reach, HPV prevalence, triage and treatment, and factors associated with follow-up completion. METHODS: We analyzed individual-level data from routinely collected forms for women attending HPV-based cervical cancer screening. HPV-positive women were triaged with Pap or visual inspection with acetic acid (VIA) prior to treatment. Logistic regression was used to identify factors associated with receiving triage and treatment; analyses were adjusted for province, age, and self- vs. provider-collected sampling. RESULTS: Forty-four thousand six hundred thirty-five women were screened with HPV testing; 96.6% of women used self-sampling. Six thousand seven hundred seventy-six women were HPV positive (15.2%), 54.0% of screen-positive women received triage, and 53.1% of triage-positive women were treated, primarily with cryotherapy. If women lost at triage are included, the overall treatment percentage was 27.8%. Province and provider sampling were significantly associated with completing triage. Province and triage type were significantly associated with receiving treatment. The odds of receiving treatment after Pap triage as compared to VIA was significantly lower (aOR: 0.05, 95% CI: 0.04-0.08, p < 0.001), and the relative proportion of women receiving treatment after Pap triage versus VIA was 0.29. CONCLUSIONS: Introduction of HPV testing resulted in a substantial number of women screened, and acceptance of self-sampling was high. Management of screen-positive women remained a challenge, particularly with Pap triage. Our results can inform other developing countries as they work to reach World Health Organization (WHO) elimination targets.

The Scale-Up project introduced vaginal self-sampling and low-cost human papillomavirus (HPV) testing as the primary approach for cervical cancer screening in selected public health centers in Guatemala, Honduras, and Nicaragua. We evaluate the country-specific accomplishments in screening: target-coverage, triage, and treatment. Between 2015 and 2018, cervical cancer screening was offered to women at least 30 years of age. Triage of HPV-positive women was based on visual inspection with acetic acid or Pap. Aggregated data included total women screened, use of self-sampling, age, time elapsed since last screening, HPV results, triage tests, triage results, and treatment. A total of 231,741 women were screened for HPV, representing 85.8% of the target populations within the project. HPV positivity was lower in Guatemala (12.4%) compared to Honduras and Nicaragua (14.5% and 14.2%, respectively, p < 0.05). A follow-up triage test was completed for 84.2%, 85.8%, and 50.1% of HPV-positive women in Guatemala, Nicaragua, and Honduras, respectively. Of those with a positive triage test, 84.7%, 67.1%, and 58.8% were treated in Guatemala, Nicaragua, and Honduras, respectively. First-time screening was highest in Nicaragua (55.8%) where self-sampling was also widely used (97.1%). The Scale-Up project demonstrated that large-scale cervical cancer screening and treatment intervention in a high-burden, low-resource setting can be achieved. Self-sampling and ablative treatment were key to the project's achievements. Data monitoring, loss to follow-up, and triage methods of screen- positive women remain critical to full success.

OBJECTIVE: To evaluate the acceptability and safety of thermal ablation (TA) for the treatment of precancerous cervical lesions in women in Honduras. METHODS: Human papillomavirus (HPV) and visual inspection with acetic acid (VIA) screen-positive eligible women received TA. After treatment, women rated the level of pain experienced during treatment using the Wong-Baker FACES® pain-rating scale from 0 to 10. Short-term safety outcomes that could require medical attention were assessed one month after treatment. RESULTS: A total of 319 women received TA treatment. The average pain rating was 2.5 (95% CI: 2.3-2.8), and 85% rated their pain levels as less than 6. No significant differences in low (below 6) or high (6 and above) pain were found by age or number of biopsies performed, but there was a significant difference by the number of TA applications (P < 0.01). When asked if they would recommend this treatment, all women said they would. At the one-month follow-up visit, the most common reported discomforts were bleeding (10%) and cramping (8.4%); 11 women reported severe lower abdominal pain, and none required medical attention. CONCLUSIONS: TA is safe and acceptable to patients as a treatment option for precancerous cervical lesions in low-resource settings.
OBJECTIF: Evaluer l'acceptabilité et la sécurité de l'ablation thermique (AT) pour le traitement des lésions cervicales précancéreuses chez les femmes au Honduras. MÉTHODES: Les femmes éligibles, portant le virus du papillome humain (VPH) et avec une inspection visuelle positive au test de dépistage à l'acide acétique (IVA) ont reçu une AT. Après le traitement, les femmes ont estimé le niveau de douleur ressenti au cours du traitement à l'aide de l'échelle d'évaluation de la douleur Wong-Baker FACES® de 0 à 10. Les résultats de sécurité à court terme pouvant nécessiter une attention médicale ont été évalués un mois après le traitement. RÉSULTATS: 319 femmes ont reçu un traitement d'AT. L'estimation moyenne de la douleur était de 2,5 (IC95%: 2,3-2,8) et 85% estimaient que leur niveau de douleur était inférieur à 6. Aucune différence significative dans la douleur faible (moins de 6) ou élevée (6 et plus) n'a été constatée en fonction de l'âge ou du nombre de biopsies réalisées, mais il y avait une différence significative selon le nombre d'applications d'AT (P < 0,01). Lorsqu'on leur a demandé si elles recommanderaient ce traitement, toutes les femmes ont répondu qu'elles le feraient. Lors de la visite de suivi à un mois, les malaises les plus fréquents signalés étaient les saignements (10%) et les crampes (8,4%). Onze femmes ont rapporté des douleurs sévères dans le bas de l'abdomen et aucune n'a nécessité de soins médicaux. CONCLUSIONS: L'AT est sûre et acceptable pour les patientes comme option de traitement pour les lésions cervicales précancéreuses dans les régions à faibles ressources.

PURPOSE: Late-stage breast cancer detection should be something of the past; however, it is still all too common in low-resource areas, including Peru, where 57% of women diagnosed with cancer are diagnosed at stage III or IV disease. Early detection of breast cancer is feasible in low-resource semirural and rural areas where mammography is rarely accessible. METHODS: PATH collaborated with Peruvian health institutions at local, regional, and national levels to design and implement a model of care for the early detection of breast cancer in Peru. The model includes training health promoters for community outreach, professional midwives in clinical breast exam, doctors to perform fine-needle aspiration biopsy sampling with ultrasound to triage, and patient navigators to ensure patients follow through with treatment. RESULTS: In a northern region of Peru, 400 individuals, including health promoters, midwives, doctors, and volunteers, received early-detection training in two phases. In Peru, local health professionals continue to refine and improve methods and materials using locally available resources, and the Peruvian health information system now includes specific breast cancer detection categories. Despite challenges and limited resources, the model is effective, and partnership with government health administrations improves health systems and benefits the population. CONCLUSION: Given the absence of screening mammography, the public health challenge is to bring breast cancer early detection and diagnostic services closer to women's homes and to ensure appropriate follow-up and care. The model is eminently transferable with appropriate adaptation and should now be tested in other settings within and outside of Peru.

OBJECTIVE: To determine the involvement of cervical intraepithelial neoplasia grade 3 (CIN3) in a population of women in a lower-resource setting. METHODS: One hundred twelve consecutive cone excision specimens with histological diagnosis of CIN3 were retrieved from the National Institute of Neoplastic Diseases in Lima Peru. Two pathologists independently evaluated each specimen microscopically and confirmed 107 cases that could be measured by optical micrometry. Depth and breadth of the lesions were measured microscopically. RESULTS: The mean maximal depth of cervical involvement by CIN3 was 2 ± 0.13 mm; depth was less than 3.5 mm in 89.7% of cases and less than 5 mm in 93.5%. Mean breadth of CIN3 was 7.3 ± 4.4 mm; breadth was less than 15.9 mm in 95% of cases and less than 20.5 mm in 99.7%. The correlation coefficient between breadth and depth of CIN3 was 0.61. No significant correlation was found between age and depth. CONCLUSIONS: Depth of CIN3 involvement in a developing country is significantly deeper than that reported in the United States. Treatment selection for women with CIN3 and risk of treatment failure may vary between developing and developed countries because of the difference in the depth of lesions. Countries with underscreened populations need to consider the increased disease severity in devising treatment strategies.

Breast cancer incidence and mortality rates continue to rise in Peru, with related deaths projected to increase from 1208 in 2012, to 2054 in 2030. Despite improvements in national cancer control plans, various barriers to positive breast cancer outcomes remain. Multiorganisational stakeholder collaboration is needed for the development of functional, sustainable early diagnosis, treatment and supportive care programmes with the potential to achieve measurable outcomes. In 2011, PATH, the Peruvian Ministry of Health, the National Cancer Institute in Lima, and the Regional Cancer Institute in Trujillo collaborated to establish the Community-based Program for Breast Health, the aim of which was to improve breast health-care delivery in Peru. A four-step, resource-stratified implementation strategy was used to establish an effective community-based triage programme and a practical early diagnosis scheme within existing multilevel health-care infrastructure. The phased implementation model was initially developed by the Breast Cancer Initiative 2·5: a group of health and non-governmental organisations who collaborate to improve breast cancer outcomes. To date, the Community-based Program for Breast Health has successfully implemented steps 1, 2, and 3 of the Breast Cancer Initiative 2·5 model in Peru, with reports of increased awareness of breast cancer among women, improved capacity for early diagnosis among health workers, and the creation of stronger and more functional linkages between the primary levels (ie, local or community) and higher levels (ie, district, region, and national) of health care. The Community-based Program for Breast Health is a successful example of stakeholder and collaborator involvement-both internal and external to Peru-in the design and implementation of resource-appropriate interventions to increase breast health-care capacity in a middle-income Latin American country.

OBJECTIVES: To evaluate the cost-effectiveness of human papillomavirus (HPV) DNA testing (versus Papanicolaou (Pap)-based screening) for cervical cancer screening in Nicaragua. DESIGN: A previously developed Monte Carlo simulation model of the natural history of HPV infection and cervical cancer was calibrated to epidemiological data from Nicaragua. Cost data inputs were derived using a micro-costing approach in Carazo, Chontales and Chinandega departments; test performance data were from a demonstration project in Masaya department. SETTING: Nicaragua's public health sector facilities. PARTICIPANTS: Women aged 30-59 years. INTERVENTIONS: Screening strategies included (1) Pap testing every 3 years, with referral to colposcopy for women with an atypical squamous cells of undetermined significance or worse result ('Pap'); (2) HPV testing every 5 years, with referral to cryotherapy for HPV-positive eligible women (HPV cryotherapy or 'HPV-Cryo'); (3) HPV testing every 5 years, with referral to triage with visual inspection with acetic acid (VIA) for HPV-positive women ('HPV-VIA'); and (4) HPV testing every 5 years, with referral to Pap testing for HPV-positive women ('HPV-Pap'). OUTCOME MEASURES: Reduction in lifetime risk of cancer and incremental cost-effectiveness ratios (ICER; 2015 US$ per year of life saved (YLS)). RESULTS: HPV-based screening strategies were more effective than Pap testing. HPV-Cryo was the least costly and most effective strategy, reducing lifetime cancer risk by 29.5% and outperforming HPV-VIA, HPV-Pap and Pap only, which reduced cancer risk by 19.4%, 12.2% and 10.8%, respectively. With an ICER of US$320/YLS, HPV-Cryo every 5 years would be very cost-effective using a threshold based on Nicaragua's per capita gross domestic product of US$2090. Findings were robust across sensitivity analyses on test performance, coverage, compliance and cost parameters. CONCLUSIONS: HPV testing is very cost-effective compared with Pap testing in Nicaragua, due to higher test sensitivity and the relatively lower number of visits required. Increasing compliance with recommended follow-up will further improve the health benefits and value for public health dollars.

BACKGROUND: Vaginal self-sampling with HPV-DNA tests is a promising primary screening method for cervical cancer. However, women's experiences, concerns and the acceptability of such tests in low-resource settings remain unknown. METHODS: In India, Nicaragua, and Uganda, a mixed-method design was used to collect data from surveys (N = 3,863), qualitative interviews (N = 72; 20 providers and 52 women) and focus groups (N = 30 women) on women's and providers' experiences with self-sampling, women's opinions of sampling at home, and their future needs. RESULTS: Among surveyed women, 90% provided a self- collected sample. Of these, 75% reported it was easy, although 52% were initially concerned about hurting themselves and 24% were worried about not getting a good sample. Most surveyed women preferred self-sampling (78%). However it was not clear if they responded to the privacy of self-sampling or the convenience of avoiding a pelvic examination, or both. In follow-up interviews, most women reported that they didn't mind self-sampling, but many preferred to have a provider collect the vaginal sample. Most women also preferred clinic-based screening (as opposed to home-based self-sampling), because the sample could be collected by a provider, women could receive treatment if needed, and the clinic was sanitary and provided privacy. Self-sampling acceptability was higher when providers prepared women through education, allowed women to examine the collection brush, and were present during the self-collection process. Among survey respondents, aids that would facilitate self-sampling in the future were: staff help (53%), additional images in the illustrated instructions (31%), and a chance to practice beforehand with a doll/model (26%). CONCLUSION: Self-and vaginal-sampling are widely acceptable among women in low-resource settings. Providers have a unique opportunity to educate and prepare women for self-sampling and be flexible in accommodating women's preference for self-sampling.

Cervical cancer is preventable but continues to cause the deaths of more than 270,000 women worldwide each year, most of them in developing countries where programs to detect and treat precancerous lesions are not affordable or available. Studies have demonstrated that screening by visual inspection of the cervix using acetic acid (VIA) is a simple, affordable, and sensitive test that can identify precancerous changes of the cervix so that treatment such as cryotherapy can be provided. Government partners implemented screening and treatment using VIA and cryotherapy at demonstration sites in Peru, Uganda, and Vietnam. Evaluations were conducted in the three countries to explore the barriers and facilitating factors for the use of services and for incorporation of screen-and-treat programs using VIA and cryotherapy into routine services. Results showed that use of VIA and cryotherapy in these settings is a feasible approach to providing cervical cancer prevention services. Activities that can help ensure successful programs include mobilizing and educating communities, organizing services to meet women's schedules and needs, and strengthening systems to track clients for follow-up. Sustainability also depends on having an adequate number of trained providers and reducing staff turnover. Although some challenges were found across all sites, others varied from country to country, suggesting that careful assessments before beginning new secondary prevention programs will optimize the probability of success.
