RESUMO

INTRODUCTION: The International Serous Fluid Cytopathology Reporting System (TIS) was developed to standardize communication among health professionals reporting analyses of serous fluid samples. The categories include non-diagnosis (ND), negative for malignancy (NFM), atypia of undetermined significance (AUS), suspected malignancy (SFM), and malignant (MAL). Each category was characterized by a risk of malignancy (ROM). METHODS: We performed a literature review to analyze studies related to TIS using several sources, including PubMed, followed by a search of relevant cytopathology journal websites (American Cancer Society, Diagnostic Cytopathology, Journal of the American Society of Cytopathology, and Acta Cytologica and Cytopathology). The search included articles published between January 2020 and December 2023, using the terms "international AND serous fluid system." RESULTS: We identified 257 articles, of which 20 addressed the inclusion and exclusion criteria. The overall ROMs for each category were 23.55% for ND, 16.46% for NFM, 50.78% for AUS, 91.34% for SFM, and 98.21% for MAL. CONCLUSION: Considering the TIS-recommended ROM rates, the ND category was between the suggested intervals, while the SFM category rate was bigger than expected. The other categories (NFM, AUS, and MAL) were below expected values. SFM and MAL had a stronger association with MAL results. New studies are needed to determine each category's ROM rate from TIS accurately.

RESUMO

OBJECTIVE: To analyze the effect of hookah and cigarettes on the oral mucosa of smokers through the use of exfoliative cytology. STUDY DESIGN: Smear samples were collected by exfoliative cytology from the tongue of 33 hookah smokers, 22 cigarette smokers, and 30 non-smokers. The selected analyses include micronuclei (MN), metanuclear anomalies, epithelial maturation, and cytomorphology (nuclear area [NA], cytoplasmic area [CA], and NA/CA ratio). RESULTS: The largest differences observed for MN and metanuclear anomalies were between cigarette smokers and the control group (notably 1 MN P = .04; total cells with MN P = .039; total MN P = .042; karyorrhexis and binucleation, P = .0001). The hookah group, compared with the control group, showed the greatest differences for karyolysis (P = .0023), binucleation (P = .0003), and broken egg (P = .008). Significant differences were found between the smokers and the control groups regarding changes in the superficial cell without nucleus, perinuclear halo, vacuolization, color change, mucus, and keratohyalin granules. There was a significant increase in the NA and NA/CA ratio in the smoker groups. CONCLUSION: This study showed that a combined analysis of exfoliative cytology associated with other diagnostic methods is a useful tool for studying oral carcinogenesis. Hookah and cigarettes showed similar effects in terms of displaying substantial cytogenetic and cytotoxic damage.

RESUMO

PURPOSE: To describe cellular alterations detected by impression cytology of the ocular surface in patients with xeroderma pigmentosum. The secondary objective was to assess the reliability of impression cytology in diagnosing ocular surface squamous neoplasia. METHODS: Patients with xeroderma pigmentosum underwent a single-day complete ophthalmological examination and impression cytology for ocular surface evaluation using 13 mm diameter mixed cellulose esters membrane filters and combined staining with Periodic Acid Schiff, Hematoxylin and Eosin, and Papanicolaou stains followed by microscopic analysis. The cytological findings were correlated with the clinical diagnosis. The impression cytology findings at baseline and one-year follow-up were correlated with the clinical course (no tumor, treated tumor, residual tumor recurrent tumor, new tumor). RESULTS: Of the 42 patients examined, impression cytology was performed in 62 eyes of 34 participants (65% females). The mean age of patients was 29.6 ± 17 years (range 7-62). Fifteen eyes had a clinical diagnosis of ocular surface squamous neoplasia. Impression cytology showed goblet cells (47, 75%), inflammatory cells (12, 19%), keratinization (5, 8%), and squamous metaplasia (30, 48%). Impression cytology was positive for atypical cells in 18 patients (12 with and 6 without ocular surface squamous neoplasia). The sensitivity, specificity, positive predictive value, and negative predictive value of impression cytology (at baseline) for diagnosis of ocular surface squamous neoplasia were 80%, 87%, 67%, and 93%, respectively, using clinical diagnosis of ocular surface squamous neoplasia as the reference standard. CONCLUSION: Impression cytology has a moderate positive predictive value for the diagnosis of ocular surface squamous neoplasia in patients with xeroderma pigmentosum. However, the lack of detection of atypical cells on impression cytology has a high negative predictive value for ocular surface squamous neoplasia. Integration of impression cytology in the long-term management of high-risk patients, such as patients with xeroderma pigmentosum, can avoid unnecessary diagnostic biopsies.

RESUMO

OBJECTIVE: The influence of age on the malignant cytology rate of thyroid nodules remains uncertain. The American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS) is currently used to guide subsequent investigations of thyroid nodules, regardless of clinical variables. This study aimed to investigate the impact of age on the malignant cytology rates of thyroid nodules and the diagnostic performance of ACR TI-RADS across different age groups. DESIGN: A retrospective, single-center, observational study. METHODS: Patients aged ≥ 20 years with thyroid nodules, who underwent fine-needle aspiration biopsy between 2012 and 2019 were evaluated. Ultrasound images were used to obtain the TI-RADS data. Malignancy was determined based on suspicious for malignancy (Bethesda V) and malignant (Bethesda VI) cytology results or malignancy in cell block analysis. RESULTS: A total of 1023 nodules from 921 patients (88.2% female) were analyzed. The median age was 58.5 (interquartile range [IQR], 41.1-66.6) years, and the median nodule size was 2.4 (IQR, 1.7-3.6) cm. Stratification by age revealed a decreasing prevalence of malignant cytology across subgroups of 20-39, 40-59, and ≥60 years (10.7%, 8.5%, and 3.7%, respectively; P = .002). After adjusting for sex, multinodularity, nodule size, and ACR TI-RADS category, we observed that each year of age reduced the OR for malignant cytology by 3.0% (95% CI: 0.7%-5.3%; P = .011). When comparing the subgroups of 20-39 and ≥60 years, the malignant cytology rate decreased by half in TI-RADS 4 (from 21.4% to 10.4%) and two-thirds in TI-RADS 5 (from 64.7% to 22.6%). CONCLUSIONS: Our study demonstrated that as patient age increased, the rate of malignant cytology in thyroid nodules decreased. Moreover, age significantly influences the malignancy rates of thyroid nodules classified according to the ACR TI-RADS.

RESUMO

Cervical cancer is the second most common form of cancer and a leading cause of premature death among women aged 15 to 44 worldwide. In Brazil, there is a high prevalence of infection by the human papillomavirus - HPV. Digital pathology optimizes time and space for reading cervicovaginal cytology slides. We evaluated the feasibility of using whole slide images (WSI) for the routine interpretation of cytology exams. A total of 99 cases of vaginal cytology were selected from a reference laboratory in Northeastern Brazil. Three cytotechnicians participated in the study. Cellular atypia was the one that most presented concordance values. Two observers almost perfectly agreed (k = 0.86 and k = 0.84, respectively) on the negative diagnoses. The performance of the evaluators for NILM (negative for intraepithelial lesion and malignancy) showed high reproducibility and sensitivity in the digital slides, mainly between evaluators A and C. In contrast, the microbiology group showed disagreement between the diagnoses by digital slides and the standard- gold. The concordance between the digital diagnoses and the gold standard for ASCUS was 89%. In the inflammatory category, Spearman's test showed similar results between raters A, B, and C (rs = 0.47, rs = 0.41, and rs = 0.47, respectively). This study reports the diagnostic validation using digital slides in view of the need to optimize the cytology visualization process. Our experience shows good diagnostic agreement between digital and optical microscopy in several analyzed categories, but mainly in relation to cellular atypia and inflammatory processes.

RESUMO

BACKGROUND: Some studies reported that differential gene expression could be used as a biomarker for high-grade cervical lesion identification. The aim was to evaluate the gene expression profile of cervical intraepithelial neoplasia (CIN) to identify a gene expression signature of CIN2+ in liquid-based cytology (LBC) samples. METHODS: LBC samples (n = 85) obtained from women who underwent colposcopy were included with benign (n = 13), CIN1 (n = 26), CIN2 (n = 16), and CIN3 (n = 30) diagnoses. After RNA isolation, gene expression profiling was performed using the nCounter PanCancer Pathways, which consists of 730 cancer-related genes. The genes identified were in silico expression evaluated using the UALCAN database. An accurate prediction model to discriminate CIN2+ from

RESUMO

INTRODUCTION: Digital cytopathology is being progressively implemented in centres worldwide, but impediments such as the three-dimensionality of specimens and the size of scanned images have prevented its use from becoming widespread. This study aimed to validate the use of digital whole slide image scanning of cytopathology samples for routine sign-out. METHODS: Specimens were scanned using the Leica Aperio GT 450 System. The following sample types were used: liquid-based cytology, direct conventional smears from fine needle aspirates and cytospins. Cases were validated by the same pathologist who originally rendered the conventional diagnosis, with a washout of at least 3 months. Final digital diagnoses were compared to the original analogical diagnoses, and cases were considered concordant up to a one-degree difference between the original and digital diagnoses. Reasons for the unsuccessful scanning of slides were also noted. The technical procedures followed the College of American Pathologists' guidelines for digital pathology validation. RESULTS: A total of 730 slides from 383 cases (337 female, 51 male; median age 42) were successfully scanned. These cases consisted of the following sample types: 81 (21.1%) conventional smears, 240 (62.7%) liquid-based cytology samples and 62 (16.2%) cytospins. There were only five discordant cases, with a 98.7% agreement between original and digital diagnoses using the difference rate of up to one degree. Seventy-seven slides (10.5%) had to be rescanned due to technical problems. The main reasons for unsuccessful scanning were paucicellular samples (44; 57.1%), the thickness of the smears (18; 23.4%) and issues with the coverslip (15; 19.5%). CONCLUSION: Cytological specimens can be successfully scanned and used for digital pathology, with excellent agreement with the original diagnoses.

RESUMO

INTRODUCTION: The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) emerged in 2015 as an attempt to establish protocols for a most appropriate follow-up and treatment of patients with salivary gland lesions. Through fine needle aspiration (FNA), a safe and minimally invasive way to obtain cytological samples, the lesion is classified into one of the six categories, which have different risks of malignancy (ROM) and, therefore, different management. MATERIALS AND METHODS: FNA cytology procedures performed between January 2016 and June 2020 (54 months) at the Pathology Institute of Araçatuba, São Paulo, Brazil, were analyzed by two pathologists with more than 5 years of experience. The ROM for each of the diagnostic categories was determines and compared with the ROM expected by the MSRSGC. RESULTS: A total of 99 FNA of salivary gland lesions were reviewed and retrospectively categorized. Histopathological follow-up was available for 58 of 96 patients (60.42%). The patients age ranged from 23 to 98 years with the mean of 58.15 ± 15.29 years. The parotid gland was the most affected (81.82%). The average size of the lesions was 2.59 cm. The ROM for each category was 16.67%, 0%, 0%, 2.86%, 50%, 100%, 100%, respectively. CONCLUSION: This is the first Brazilian study describing the application of the MSRSGC in the routine of a private Laboratory out of a cancer center service. Therefore, it is an effective method in the classification of salivary gland lesions, when associated with the MSRSGC, to determine the ROM and its appropriate treatment.

RESUMO

BACKGROUND: Intraoperative cytology (IC) is an alternative to frozen-section (FS) diagnosis. We present our experience with and the diagnostic value of IC during a 7-year period when FS was not available in a Peruvian Cancer Center. MATERIAL AND METHODS: This 7-year retrospective single-arm review study includes IC procedures performed by three pathologists between 2012 and 2018. These IC reports were reviewed independently by one pathologist and were correlated with the histologic diagnoses, which were used as the gold standard. All IC preparations (imprint, scrape, and crush smears) were stained with hematoxylin and eosin. IC interpretations were categorized as: malignant, benign, atypical, and "deferred to permanent sections." Sensitivity, specificity, and positive and negative predictive values were calculated by use of standard methods. RESULTS: A total of 1814 IC cases prepared from various organs obtained from 887 patients were reviewed. Malignant, benign, atypical, and "deferred to permanent sections" IC diagnoses were 26.3%, 68.9%, 3.7%, and 1.9%, respectively. Atypical and deferred cases were excluded from the statistical analysis; thus 1712 cases were found to be eligible. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and overall diagnostic accuracy were 91.6%, 97.7%, 94.1%, 96.7%, and 96%, respectively. CONCLUSION: In experienced hands, IC is a rapid, cost-effective, and accurate alternative diagnostic modality for intraoperative diagnosis when FS is not available.

RESUMO

Introdução: A alopecia androgenética é a alopecia não cicatricial mais comum em homens e mulheres e, por isso, uma das principais queixas dermatológicas da tricologia nos consultórios médicos e o líquen planopilar é uma doença inflamatória linfocítica que causa perda definitiva de cabelos e pode ser confundida com baixa pega ou perda de enxertos pós transplante capilar. Devido a escassez de dados na literatura sobre os achados clínicos, tricoscópicos e histopatológicos de uma evolução normal de transplante capilar após um ano de evolução desenvolvemos este estudo, para ajudar os profissionais de saúde a guiar suas biópsias para que o diagnóstico diferencial de líquen planopilar não seja feito erroneamente, já que o padrão inflamatório de um quadro normal pode ser semelhante ao dessa patologia. Objetivo: Observar biópsias de enxertos de pacientes com alopecia androgenética após mais de 1 ano de transplante capilar não complicado e discutir se os achados histológicos são ainda semelhantes ao líquen planopilar e podem, neste ponto, causar confusão diagnóstica. Metodologia: Foi realizado um estudo transversal em 9 pacientes com diagnóstico de alopecia androgenética submetidos a transplante capilar bem sucedido com pelo menos 12 meses de cirurgia. Resultados: Observou-se através da avaliação histopatológica da área de enxerto capilar de aspecto normal no local transplantado e da área com achados de alopecia androgenética adjacente, não submetida ao transplante capilar, uma tendência a ausência de inflamação e fibrose periístmica. Conclusão: Após um ano de transplanta capilar, o processo inflamatório causado pelo procedimento em si não pareceu se manter, diminuindo a chance de um diagnóstico diferencial de líquen planopilar. Entretanto, novos estudos com maior amostra são necessários para corroborar com esses dados. Palavras-chave: Alopecia androgenética. Transplante autólogo. Histopatologia. Líquen plano pilar.

RESUMO

Intrathyroidal thymus tissue (ITTT) is a rare, benign condition; its diagnosis can prove challenging due to unfamiliarity with this entity. However, it has ultrasonographical and cytological characteristics which can suggest its presence and thus should be considered in the differential diagnosis of thyroid nodules. Presently, immunohistochemistry can be used with fine needle aspiration (FNA) cytology, thus decreasing the need for unnecessary surgery. We discuss the usefulness of immunohistochemistry in thyroid cytology, with reference to a case of a 10-year-old patient, who underwent partial thyroidectomy for a suspicious thyroid nodule which was eventually diagnosed as ITTT by the histopathology of the surgical specimen.

RESUMO

Introducción: La prótesis dental completa genera una reacción tisular en el medio bucal, cuyo diagnóstico puede ser confirmado mediante el estudio citológico, que constituye una herramienta imprescindible para identificar cambios displásicos tempranos de la mucosa subprótesis. Objetivo: Identificar las posibles variaciones celulares de la mucosa bucal en pacientes portadores de prótesis completa. Métodos: Se realizó un estudio descriptivo y transversal en la Clínica Estomatológica Provincial Docente Mártires del Moncada de Santiago de Cuba, de junio de 2014 a enero de 2019, de 100 pacientes atendidos en la consulta de Prótesis Estomatológica, a los cuales se les realizó el raspado citológico de la mucosa del paladar y los rebordes para su posterior análisis microscópico según variables de interés. Para el procesamiento estadístico se empleó el porcentaje como medida de resumen y el estadígrafo de la Χ2, con un nivel de significación de 0,05. Resultados: En la serie predominaron las displasias leves (66,7 %), que resultaron más frecuentes en las edades de 20 a 39 años (12,5 %), en tanto, las moderadas y las graves figuraron principalmente en el grupo etario de 60 y más años (9,3 y 27,7 %, respectivamente). Todos los tipos de displasia primaron en los pacientes que habían portado la prótesis por más de 5 años y afectaron mayormente la queratina; de igual modo, entre las lesiones observadas, la estomatitis afectaba a un mayor porcentaje (31,2), sobre todo en el paladar (82,3 %), mientras que 8,3 % correspondió a la leucoplasia. Conclusión: Las pruebas citológicas son imprescindibles para la confirmación diagnóstica de cambios displásicos y posibilitan la prevención temprana del cáncer bucal.


Introduction: The complete dental prosthesis generates a tisular reaction in the oral cavity which diagnosis can be confirmed by means of citological study that constitutes an indispensable tool to identify early dysplastic changes of the subprosthesis mucous. Objective: To identify the oral possible cellular variations of the oral mucous in patients with complete prosthesis. Methods: A descriptive and cross sectional study was carried out in Mártires del Moncada Provincial Stomatological Clinic of Santiago de Cuba, from June, 2014 to January, 2019, with 100 patients, assisted in the Stomatological Prosthesis Department to whom the cytological scrapings of the palate and the edges were carried out for their later microscopic analysis according to variables of interest. For the statistical procedures, the percentage was used as summary measure and the Chi squared statistician, with a significance level of 0,05. Results: In the series the mild dysplasias prevailed (66,7%) that were more frequent in the 20 to 39 age group (12,5%), while the moderate and the serious dysplasias figured mainly in the age group of 60 and over (9,3 and 27,7%, respectively). All the dysplasia types prevailed in the patients that had carried the prosthesis for more than 5 years and they mostly affected the keratin; in a same way, among the observed lesions, the stomatitis affected a higher percentage (31,2), mainly in the palate (82,3%), while 8,3% corresponded to the leukoplakia. Conclusion: The cytological checkups are indispensable for the diagnostic confirmation of dysplasic changes and they allow to prevent early oral cancer.

RESUMO

Background: Sporotrichosis is a zoonotic disease caused by a dimorphic fungi of the Sporothrix schenckii complex. It isan emerging zoonosis with worldwide distribution, thus of great importance to public health. The infection occurs fromtraumatic inoculation of the fungus in the human skin from contaminated plants and soils and through bites or scratchesof infected animals. The occurrence of sporotrichosis has been related to zoonotic transmission, especially by domesticfelines. This work aims to report the successful use of itraconazole as monotherapy in a case of localized feline sporotrichosis and highlight the effectiveness of cytology in its diagnosis.Case: A 1-year-and-4-month-old spayed female cat undefined breed, weighing 3.1 kg, was referred to the VeterinaryMedical Teaching Hospital of the Universidade Estadual de Maringá (UEM), city of Umuarama, presenting a serosanguinous ulcerative lesion located in the left periocular region The clinical picture of the patient progressed over 3 months.Treatments with antibiotic therapy, corticosteroids, and surgical procedures were conducted, without clinical improvement. A new lesion in the distal portion of the thoracic limb emerged, proving that the disease remained in progression.Hematological exams were performed, among them hemogram, renal and hepatic biochemical analyses, SNAPS to identifythe feline immunodeficiency virus feline leukemia virus (FIV/FeLV), and cytology of the lesion through imprints. Thehematological results were all within the normal standards for the species. Cytology showed a large amount of oval andfusiform structures phagocyted by polymorphonuclear cells, free at the bottom of the slide, compatible with Sporothrixspp. The treatment administered was itraconazole (100 mg/cat), orally administered every 24 h, cefovecin sodium 8 mg/kg,subcutaneous, single dose, topical use of...(AU)

RESUMO

Objective: Squamous cell carcinoma of the anus (SCCA) is associated with human papillomavirus (HPV) infection in almost 90% of the cases. Its incidence is alarmingly high among men who have sex with men (MSM) and continues to increase at an average rate of 2% per year. The objective of the present study is to evaluate the usefulness and performance of liquid-based anal cytology as a screening tool for prevention and early detection of SCCA in a cohort of at-risk men. Method: We conducted a retrospective study including 111 MSM, aged between 22 and 62 years old, who underwent anal cytological screening with a liquid-based Pap test at our sexually transmitted diseases (STDs) clinic from January 2015 to March 2017. Results: Out of 111 anal smears, 57 (51,4%) resulted negative, 42 (37,8%) abnormal, and 12 (10,8%) unsatisfactory for the cytological evaluation. Only patients with an abnormal cytology underwent anoscopy and subsequent biopsy. The histological results were as follows: negative for squamous intraepithelial lesion (SIL) in 5 cases, low-grade SIL (L-SIL) in 21, high-grade SIL (H-SIL) in 5, SCCA in 1. Five patients had a normal anoscopy and biopsy was not taken. Conclusion: Liquid-based cytology, reducing the "darkening factors" typical for the conventional smears, has a higher positive predictive value than the traditional technique. Moreover, a cytological diagnosis of atypical squamous cells of undetermined significance (ASC-US) or L-SILmay hide a severe dysplasia or even a carcinoma. Thus, all patients with an abnormal anal cytology at any grade should be considered for anoscopy. (AU)

RESUMO

Resumen Objetivo: Describir las características demográficas del cáncer de tiroides en la Región de Ñuble en pacientes operados en el servicio de cirugía del Hospital Clínico Herminda Martin del 2017 al 2019. Materiales y Método: Mediante estudio descriptivo, se revisaron las historias clínicas de los pacientes operados en la Unidad de Cirugía de Adultos del hospital entre enero de 2017 y diciembre de 2019, tabulando las variables demográficas, clínicas e histopatológicas y método diagnóstico. Resultados: Se operaron 124 pacientes con afecciones tiroideas, 58 resultaron tener cáncer. Predominó el sexo femenino (50 pacientes). Se realizaron 43 tiroidectomías totales como primera cirugía y 15 disecciones cervicales. El carcinoma papilar fue el más diagnosticado (93,1%). Hubo discrepancias entre las categorías Bethesda II y IV en cuanto al diagnóstico definitivo. En mujeres el 36% de los tumores tuvo extensión extra tiroidea y el 54% tenían un diámetro mayor a 1 cm. Discusión: La prevalencia en el sexo femenino corresponde con los datos que se aportan a nivel mundial y en Chile. La discrepancia en el sistema Bethesda pudo corresponder a errores de la toma de muestra o su interpretación citológica. Los hallazgos de extensión y tamaño tumoral pueden estar en relación con el tiempo de espera para la cirugía. Conclusiones: El cáncer tiroideo es más frecuente en el sexo femenino. El carcinoma papilar fue el más diagnosticado. La asociación de tiroiditis con cáncer tiroideo fue de 98%. No se realizó ninguna cirugía conservadora.


Aim: To describe the demographic characteristics of thyroid cancer in the Ñuble Region in patients operated on by the Herminda Martín de Chillán Clinical Hospital surgery service from 2017 to 2019. Materials and Method: Through a descriptive study, the medical records of the patients operated on in the Adult Surgery Unit of the hospital between January 2017 and December 2019 were reviewed, tabulating the demographic, clinical and histopathological variables and method diagnosis. Results: 124 patients with thyroid conditions were operated on, 58 had cancer. The female sex predominated (50 patients). 43 total thyroidectomies were performed as the first surgery and 15 cervical dissections. Papillary carcinoma was the most diagnosed (93.1%). There were discrepancies between Bethesda categories II and IV regarding the definitive diagnosis. In women, 36% of the tumors had an extra-thyroid extension and 54% had a diameter greater than 1 cm. Discussion: The prevalence in the female sex corresponds to the data provided worldwide and in Chile. The discrepancy in the Bethesda system could correspond to errors in the sampling or its cytological interpretation. The findings of tumor extension and size may be related to the waiting time for surgery. Conclusions: Thyroid cancer is more frequent in females. Papillary carcinoma was the most diagnosed. The association of thyroiditis with thyroid cancer was 98%. No conservative surgery was performed.

RESUMO

The World Health Organization global call to eliminate cervical cancer encourages countries to consider introducing or improving cervical cancer screening programs. Brazil's Unified Health System (SUS) is among the world's largest public health systems offering free cytology testing, follow-up colposcopy, and treatment. Yet, health care networks across the country have unequal infrastructure, human resources, equipment, and supplies resulting in uneven program performance and large disparities in cervical cancer incidence and mortality. An effective screening program needs multiple strategies feasible for each community's reality, facilitating coverage and follow-up adherence. Prioritizing those at highest risk with tests that better stratify risk will limit inefficiencies, improving program impact across different resource settings. Highly sensitive human papillomavirus (HPV)-DNA testing performs better than cytology and, with self-collection closer to homes and workplaces, improves access, even in remote regions. Molecular triage strategies like HPV genotyping can identify from the same self-collected sample, those at highest risk requiring follow-up. If proven acceptable, affordable, cost-effective, and efficient in the Brazilian context, these strategies would increase coverage while removing the need for speculum exams for routine screening and reducing follow-up visits. SUS could implement a nationwide organized program that accommodates heterogenous settings across Brazil, informing a variety of screening programs worldwide.
