RESUMO
Introdução: O diagnóstico precoce e referenciamento ao serviço especializado são essenciais para melhorar as taxas de cura e sobrevida das mulheres acometidas pelo câncer de colo de útero. Assim, a realização deste estudo tornará possível o levantamento de informações que serão essenciais para o desenvolvimento de medidas preventivas, que almejam contribuir com o desenvolvimento de ações de educação em saúde e o diagnóstico precoce para reduzir a morbimortalidade dessa enfermidade. Objetivo: Identificar o perfil dos resultados dos exames citopatológicos do colo do útero de mulheres residentes no estado de Minas Gerais a partir dos dados de exames correspondentes ao ano de 2019, utilizando as variáveis disponibilizadas pelo Sistema de Informação do Câncer. Métodos: Trata-se de um estudo retrospectivo, exploratório, quantitativo realizado por meio de base de dados secundários. Os dados foram submetidos à análise no software SPSS, versão 20.0. Realizou-se estatística descritiva (frequência absoluta, porcentagem, média e desvio padrão). Para verificar associação entre variáveis qualitativas foi utilizado teste qui-quadrado (x²) e exato de Fisher. A força das associações entre as variáveis foi aferida pelo risco relativo (RR) e intervalos de confiança (IC 95%). Resultados: As principais alterações presentes nos exames foram: alterações por células escamosas atípicas de significado indeterminado e lesão intraepitelial de baixo grau. Após análises estatísticas, notou-se que algumas alterações possuem risco maior de se desenvolverem no público fora da faixa etária preconizada, ou seja, entre mulheres com idade <25 anos ou >64 anos. Conclusão: O estudo realizado contribui para identificação do perfil atual vivenciado na área da saúde da mulher e possibilita a criação de condutas e ações que visem intervir frente aos resultados obtidos, impactando positivamente na realidade de Minas Gerais
Introduction: Early diagnosis and referral to a specialized service are essential to improve the cure and survival rates of women affected by cervical cancer. Thus, carrying out this study will make it possible to collect information that will be essential for the development of preventive measures, which aim to contribute to the development of health education actions and early diagnosis to reduce the morbidity and mortality of this disease. Objective: Identify the profile of the results of cervical cytopathological examinations of women residing in the State of Minas Gerais from the data of examinations corresponding to the year 2019, using the variables made available by the Cancer Information System.Methods: This is a retrospective, exploratory, quantitative study carried out by means of a secondary database. The data were submitted to analysis using the SPSS software, version 20.0. Descriptive statistics (absolute frequency, percentage, mean and standard deviation) were performed. To verify the association between qualitative variables, the chi-square test (x²) and Fisher's exact test were used. The strength of the associations between the variables was measured by the relative risk (RR) and confidence intervals (95% CI). Results: The main alterations present in the cytopathological exams performed were: changes due to atypical squamous cells of undetermined significance and low- grade intraepithelial lesion. After statistical analysis, it was noted that some changes have a higher risk of developing in the public outside the recommended age range, that is, among women aged <25 years or> 64 years. Conclusion: The study carried out contributes to the identification of the current profile experienced in the area of women's health and enables the creation of conducts and actions that aim to intervene in view of the results obtained, positively impacting the reality of Minas Gerais.

Objetivo: Com o presente estudo, buscou-se verificar a quantidade de exames de colpocitologia oncótica coletados em Unidade Básica de Saúde (UBS) escolhida, determinar quantas e quais são as alterações encontradas nesses exames e quais foram as condutas e acompanhamentos realizados em pacientes com exames alterados. Métodos: Foram analisados 446 exames de colpocitologia oncótica realizados em uma UBS do centro-oeste do Paraná. As pacientes com exame alterado foram selecionadas e foi feita uma análise desses prontuários a fim de verificar a conduta e o acompanhamento dessas pacientes. Resultados: Foram encontrados 32 exames com alterações, sendo três de uma mesma paciente. Dessas 30 pacientes, a grande maioria correspondia a células escamosas atípicas de significado indeterminado (ASC-US), possivelmente não neoplásicas, e 28 pacientes retornaram para receber uma conduta inicial, sendo principalmente o encaminhamento para a coleta de novo preventivo em seis meses ao serviço de oncologia clínica. Conclusão: O presente estudo concluiu que a hipótese principal foi verdadeira, a qual foi descrita como prevalência significativa de lesões intraepiteliais de alto grau, embora não seja a mais frequente, e descontinuidade por parte das pacientes que obtiveram esse resultado. Além disso, notou-se grande encaminhamento à atenção terciária, o que não é indicado pelo Ministério da Saúde.(AU)
Objective: With the present study, we sought to verify the amount of cytopathological tests collected in the chosen basic health unit, to determine how many and what are the alterations found in these tests and what were the conducts and follow-ups performed in patients with altered exams. Methods: We analyzed 446 preventive tests performed in a basic health unit in the Midwest of Paraná, and patients with altered examination were selected and an analysis of these medical records was made in order to verify the conduct and follow-up of the patients. Results: Thirty-two tests with alterations were performed, 3 of which were the same patient. Of these 30 patients, the vast majority corresponded to atypical cells of squamous meaning possibly non-neoplastic (ASC-US), and 28 patients returned to receive an initial approach, mainly being referred to the collection of preventive new in 6 months and to the clinical oncology service. Conclusion: The present study concluded that the main hypothesis was true, which was described as a significant prevalence of high-grade intraepithelial lesions (HSIL), although not the most frequent, and discontinuity on the part of the patients who obtained this result. In addition, there was a large referral to tertiary care, which is not indicated by the Ministry of Health.(AU)

O papilomavírus humano (HPV) infecta pele e mucosas e causa, na grande maioria dos casos, lesões transitórias que podem evoluir para câncer. O objetivo deste estudo é avaliar, por meio de revisão integrativa, a literatura disponível sobre a frequência da infecção pelo HPV na região Sul do Brasil. Buscou-se nas bases de dados PubMed, Literatura Latino-americana e do Caribe em Ciências da Saúde (Lilacs) e Scientific Electronic Library Online (SciELO) a frequência de HPV na região Sul do Brasil nos últimos dez anos. Foram identificados oito estudos que se enquadraram nos critérios da pesquisa. A prevalência estimada de infecção pelo HPV foi de 46,19%. Os genótipos mais encontrados foram HPV 6, de baixo risco, e os subtipos HPV 16, HPV 18, HPV 31 e HPV 58, de alto risco. Nas amostras classificadas como LSIL/HSIL ou de células escamosas atípicas (ASC), tipos virais de baixo risco HPV 6, HPV 11 e HPV 44 foram os mais prevalentes, enquanto para os de alto risco os subtipos HPV 16, HPV 18 e HPV 58 foram os mais encontrados. Embora tenham sido identificados poucos estudos com essa temática nos últimos anos, a partir dos dados da pesquisa foi possível estimar a prevalência do HPV no Sul do Brasil e seus genótipos mais frequentes. Essa informação é importante para o planejamento das ações de saúde pública e dos serviços de saúde, contribuindo para a elaboração de estratégias de controle e prevenção da infecção.
Human Papillomavirus (HPV) infects skin and mucous membranes, and, in most cases, causes transient lesions that can progress to cancer. Given this scenario, this integrative review sought to evaluate the available literature on the frequency of HPV infection in southern Brazil. Bibliographic search was conducted on the PubMed, Latin American and Caribbean Literature on Health Sciences (Lilacs) and Scientific Electronic Library Online (SciELO) databases for papers on the frequency of HPV in southern Brazil published in the last ten years. Eight studies were identified. Estimate of HPV infection prevalence was 46.19%. Low-risk HPV 6 and high-risk HPV 16 were the most common genotypes, and HPV 18, HPV 31 and HPV 58 the most common subtypes. Risky viral types HPV 6, HPV 11 and HPV 44 were most prevalent in cellular changes classified as LSIL/HSIL or atypical squamous cell (ASC), whereas HPV 16, HPV 18 and HPV 58 prevailed as the high risk subtypes. Despite the small sample size of recent studies, the review was able to identified the prevalence of HPV infection in southern Brazil and its most common genotype, essential information for elaborating public health strategies and preventing infections.

Abstract Objective To evaluate the performance of the hybrid capture 2 (HC2) high-risk papillomavirus (hrHPV) assay and cytological test in women with previous abnormalities, to detect cervical intraepithelial neoplasia grade 2 or worse (≥ CIN 2). Methods A cytological test and HC2 (Qiagen, Gaithersburg, Maryland, EUA) for hrHPV were conducted in 359 liquid-based (Sure Path, Becton Dickinson, TriPath Imaging, Burlington, NC, USA) samples collected from women from the Vale do Ribeira Region, during July 2013 and September 2015 with previous cytology classified as atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL), atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesions (ASC-H), and atypical glandular cells (AGC). The histopathological examination was conducted in 179 women. The performance evaluations were calculated using the "exact" Clopper-Pearson 95% confidence interval (CI) test by MEDCALC (Medcalc Software Ltd, Ostend, Belgium). Results The ≥ CIN 2 frequency was 11.7% (21/179). The HC2 for hrHPV and repeat cytology to detect ≥ CIN 2 obtained, respectively, a sensitivity of 90.5% (95% CI = 69.6-98.8) and 90.5%, (95%CI = 69.6-98.8), a specificity of 65.8% (95% CI = 57.9-73.2) and 43.7% (95%CI = 35.8-51.8), a positive predictive value of 26.0% (95% CI = 21.4-31.3) and 17.6%, (95%CI = 14.9-20.6), and a negative predictive value of 98.1% (95%CI = 93.3-99.5) and 97.2% (95% CI = 90.1-99.2). Conclusion Hybrid capture 2 for hrHPV improves the performance of the detection of ≥ CIN 2, without compromising sensitivity, and provides a greater safety margin to return to the triennial screening of women undergoing follow-up due to previous abnormalities, without underlying ≥ CIN 2.
Resumo Objetivo Avaliar o desempenho da captura híbrida 2 (CH2) para papilomavírus humano de alto risco (HPVar) e repetição do exame citopatológico em mulheres com anormalidades em citologia anterior, para detectar neoplasia intraepitelial cervical grau 2 ou pior (≥ NIC 2). Métodos Foi realizado exame citopatológico e CH2 para HPVar (Qiagen, Gaithersburg, Maryland, EUA) em 359 amostras em meio líquido (Sure Path, Becton Dickinson, TriPath Imaging, Burlington, NC, USA) coletadas de mulheres da região do Vale do Ribeira, durante julho de 2013 e setembro de 2015 com citologia anterior classificada como células escamosas atípicas de significado indeterminado (ASC-US), lesão intraepitelial de baixo grau (LSIL), células escamosas atípicas, não podendo excluir lesão de alto grau (ASC-H) e células glandulares atípicas (AGC). O exame histopatológico foi realizado em 179 mulheres. As avaliações de desempenho foram calculadas usando o teste de intervalo de confiança (IC) "exato" de Clopper-Pearson de 95% pelo software MEDCALC (Medcalc Software Ltd, Ostend, Bélgica). Resultados A frequência de≥ NIC 2 foi 11,7% (21/179). A CH2 para o HPVar e a citologia de repetição para a detecção ≥ NIC 2 obteve, respectivamente, sensibilidade de 90.5% (IC 95% = 69,6-98,8) e 90,5% (IC 95% = 69,6-98,8), especificidade de 65,8% (IC 95% = 57,9-73,2) e 43,7%, (IC 95% = 35,8-51,8), valor preditivo positivo de 26,0% (IC 95% = 21,4-31,3) e 17,6%, (IC95% = 14,9-20,6), e valor preditivo negativo de 98,1% (IC 95% = 93,3-99,5) e 97,2%, (IC 95% = 90,1-99,2). Conclusão No geral, a CH2 para HPVar aprimora o desempenho para detecção de ≥ NIC 2, sem comprometer a sensibilidade e proporciona maior margem de segurança do retorno ao rastreio trienal de mulheres com anormalidades citológicas prévias, sem≥ NIC 2 subjacente.

Resumen Introducción: La infección genital por el Virus de Papiloma Humano (VPH) se ha asociado con el cáncer cérvicouterino (CCE) al provocar la aparición de lesiones precursoras de cáncer en la zona de transformación de la unión escamo-columnar del cuello uterino. Existen más de 100 tipos de VPH, clasificados en bajo riesgo oncogénico (VPH-BR) y alto riesgo oncogénico (VPH-AR). Estudios reportan la infección por genotipos de alto riesgo en el 100% de los CCE. En Venezuela, el 67,7% de los CCE, se relacionan con el genotipo de VPH-AR 16. Objetivo: Detectar la presencia de VPH en pacientes con cambios citológicos cervicouterino. Metodología: Se incluyeron 49 pacientes que presentaban cambios citológicos, se tomaron las muestras de la región endocervical y exocervical para la detección y genotipificación del virus mediante la técnica de Multiple PCR. Resultados: Las alteraciones citológicas presentes fueron Células Escamosas Atípicas (69,4%), Células Glandulares Atípicas (4,1%), Lesión Escamosa Intraepitelial de Bajo Grado (16,3%), y Lesión Escamosa Intraepitelial de Alto Grado (10,2%). La detección molecular demostró que 16,3% presentaba VPH, 62,5% correspondían a VPH-AR, 25% a VPH-BR, 12,5% al genotipo 16 y no se detectó el genotipo 18. Se reportó un solo caso de coinfección. Conclusiones: A diferencia de otros estudios, no se encontró una relación estadísticamente significativa entre la presencia del virus y la aparición de cambios citológicos cervicouterino en esta población. No obstante, se detectaron genotipos de alto riesgo oncogénico, lo que puede traducirse en una mayor incidencia de cáncer cervicouterino a futuro.
Abstract Introduction: Genital infection by the Human Papilloma Virus (HPV) has been associated with cervical cancer (CC) since it causes the appearance of precursor cancer lesions in the transformation area of the squamous-columnar junction of the cervix. There are more than 100 types of HPV that are classified as low oncogenic risk (LR-HPV) and high oncogenic risk (HR-HPV). Studies report that the infection by high-risk genotypes is present in 100% of CC. In Venezuela, 67.7% of CC is related to the HPV-16 genotype. Objective: This study seeks to detect the presence of HPV in patients with cervical cytological cell changes. Methodology : Forty-nine patients with cytological changes were studied. The endocervical and ectocervical areas were sampled to detect and genotype the virus by using the Multiplex PCR technique. Results: The cytological alterations presented were: Atypical Squamous Cells (69.4%), Atypical Glandular Cells (4.1%), Low-grade Squamous Intraepithelial Lesion (16.3%) and High-grade Squamous Intraepithelial Lesion (10.2%). Besides, the general molecular detection showed that 16.3% had HPV, 62.5% of it corresponded to HR-HPV, 25% to LR-HPV, and 12.5% to genotype 16. The genotype 18 was not detected, and only one co-infection case was reported. Conclusions: Unlike other studies, a statistically significant relationship was not found between the virus presence and the appearance of cervical cytological cell changes in this population. However, genotypes with high oncogenic risk were detected, which may lead to a higher incidence of cervical cancer in the future.

OBJECTIVE: Human papillomavirus (HPV) infection is the most important risk factor for cervical cancer, which progresses from precursor lesions with no symptom if left untreated. We compared the risk of cervical dysplasia among HPV-positive Korean women based on HPV types and infection patterns. METHODS: We observed participants of a 5-year multicenter prospective cohort study, comprising HPV-positive women with either atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion of the cervix at their enrollment. Follow-ups, comprising cytology and HPV DNA testing results, were included in the final analysis. Incidence was calculated for each infection pattern (persistent infection, incidental infection, and clearance). To investigate cervical dysplasia risk, we used Cox proportional hazard models adjusted for variables that were significantly different among infection patterns. From April 2010 to September 2017, 71 of 1,027 subjects developed cervical dysplasia more severe than high-grade squamous intraepithelial lesion of the cervix. RESULTS: Of these 71 subjects, persistent infection, incidental infection, and clearance were noted in 30, 39, and 2 individuals, respectively. Based on changes in DNA results during follow-up, cumulative incidence was 27.2%, 10.4%, and 0.5% for persistent infection, incidental infection, and clearance, respectively. Compared to clearance, the adjusted hazard ratios for cervical dysplasia were 51.6 and 24.1 for persistent and incidental infections, respectively (p < 0.001). CONCLUSION: Individuals persistently infected with the same HPV types during the follow-up period had the highest risk of severe cervical dysplasia. Hence, it is necessary to monitor HPV types and infection patterns to prevent severe cervical precancerous lesions.

Primary intraosseous squamous cell carcinoma is a rare malignant central jaw tumor derived from odontogenic epithelial remnants. Predominantly, it affects mandible, although both jaw bones may be involved. This report describes a 60-year-old man who was initially misdiagnosed with a periapical infection related to the right lower wisdom tooth. After four months, the patient presented to a private dental clinic with a massive swelling at the right side of the mandible. Panoramic radiographs and advanced imaging revealed a lesion with complete erosion of the right ramus, which extended to the orbital floor. A biopsy from the mandibular angle revealed large pleomorphic atypical squamous cells, which is the primary microscopic feature of a poorly differentiated squamous cell carcinoma.

Células escamosas atípicas de significado indeterminado (ASC-US) é uma categoria bastante subjetiva, que abrange alterações morfológicas, as quais, qualitativamente ou quantitativamente, são insuficientes para definir uma lesão intraepitelial escamosa. Dados da literatura afirmam que aproximadamente 75% retornam à normalidade após repetição da citologia, porém, parte delas, na histologia, são lesões com alto potencial neo¬plásico. Objetivos: Avaliar o seguimento de mulheres com ASC-US e a adesão às condutas preconizadas. Métodos: Foi realizada busca dos exames posteriores das mulheres com resultado de ASC-US em 2015, atendidas no Núcleo de Anatomia Patológica do Instituto Adolfo Lutz. Foram avaliados o tempo médio de repetição, idade e exame posterior. Resultados: Das 675 mulheres participantes do estudo, 71,7% repetiram a citologia com intervalo médio de 9 meses e média de idade de 37 anos. Na citologia de repetição, 77,7% foram NILM. Dos exames de repetição alterados, 1,7% (8/484) foi HSIL na citologia, 13,3% (4/30) foram NIC e 3,3% (2/3) foram CAI na histologia. Considerando as diretrizes brasileiras, 17,5% das mulheres abaixo dos 25 anos, 39,9% entre 25 e 64 anos e 34,4% acima dos 65 repetiram o exame no intervalo recomendado. Conclusão: A maioria dos resultados posteriores foi negativa, porém, uma parte considerável das mulheres apresentou alteração no exame de repetição. Dos exames histopatológicos realizados, a maioria apresentou resultado de cervicite, porém, foram detectadas lesões mais graves subjacentes em 16,6% destas mulheres, evidenciando a importância do acompanhamento e investigação apropriada.

A atenção em saúde destinada a mulheres jovens, especialmente adolescentes, mostra-se um desafio, visto que, nesse grupo, apesar da maior incidência e prevalência de infecções genitais por HPV, há também maior probabilidade de regressão de lesões, com resolução espontânea na maioria das vezes. Frente a isto, surgem questionamentos quanto ao período ideal para início do rastreio do câncer de colo uterino e ao manejo das possíveis alterações citológicas. Em janeiro de 2016, o Instituto Nacional de Câncer (INCA) publicou a segunda edição, revisada e atualizada, das Diretrizes Brasileiras para Rastreamento do Câncer do Colo do Útero. Tal documento fornece as recomendações de rastreamento e seguimento para cada grupo de atipias citológicas, inclusive em populações especiais como adolescentes e gestantes. O presente artigo visa expor as recomendações no cuidado de adolescentes com citologia oncótica do colo uterino alterada, com base nas novas Diretrizes.(AU)
Health care for young women, especially adolescents, is challenging, since in this group, in spite of the higher incidence and prevalence of genital HPV infections, there is also a greater probability of regression of lesions, with spontaneous resolution in the majority of the times. Faced with this, questions arise regarding the ideal period for the beginning of cervical cancer screening and the management of possible cytologic alterations. In January 2016, the National Cancer Institute published the second, revised and updated edition of the Brazilian Guidelines for the Screening of Cervical Cancer. This document provides the recommendations for tracking and follow-up for each group of cytologic atypia, including in special populations such as adolescents and pregnant women. The present article aims to expose the recommendations in the care of adolescents with altered uterine cervical cytology, based on the new Guidelines.(AU)

Objetivo: Analisar a prevalência dos resultados positivos para ASC em uma população da rede privada em Caxias do Sul e sua associação com o HPV. Métodos: Foram analisados resultados de exames citopatológicos do colo uterino no período de 2015 a 2017. Para presença de HPV foram avaliados os resultados histopatológicos da biópsia e de biologia molecular por reação em cadeia polimerase (PCR). Resultados: A prevalência de ASC foi de 2,48%, sendo que 58% das pacientes realizaram seguimento. A histopatologia mostrou prevalência de HPV, associado às lesões cervicais em 46,4% e 59,4% para ASC-US e ASC-H respectivamente. A prevalência de HPV no teste de PCR foi de 30,4%, sendo os subtipos mais prevalentes o HPV16 e 18. Conclusão: O percentual de exames de ASC em uma população de Caxias do Sul mostrou-se dentro dos valores adequados. Na histopatologia houve uma maior associação de ASC-H com lesões de alto grau e presença de HPV. Isso mostra a necessidade e a importância do seguimento das pacientes com resultados de ASC, principalmente para ASC-H.

Abstract Objective To assess the management chosen by gynecologists after atypical squamous cells (ASCs) cytology results, and to evaluate the outcomes of these cases in Brazilian women. Methods A prospective observational study evaluated the initial management offered by the gynecologist in the case of 2,458 ASCs cytology results collected between January of 2010 and July of 2016. The outcomes of the cytology, high-risk human papilloma virus (HR-HPV) test and histology were compared in two subgroups: atypical squamous cells of undetermined significance (ASC-US) and atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (ASC-H). Results In many cases of ASC-US (36.97%) and ASC-H (40.50%), no clinical actions were taken. Cytology was the most frequent follow-up chosen, including for cases of ASC-H, which goes against the conduct recommended in the national guideline. In women over 30 years of age, the period of time elapsed between an ASC-US result and a new cytology was in 13.03 months, in disagreement with the national guideline recommendations (p< 0.0001). Negative for intraepithelial lesions or malignancy (NILM) cytologic (p = 0.0026) and histologic (p = 0.0017) results in the follow-up were associated with prior ASC-US, while negative results for ASC-H were cytologically (p< 0.0001) and histologically associated with high-grade squamous intraepithelial lesion (HSIL) (p< 0.0001). Two invasive cervical carcinomas (ICCs) were found in the follow-up for ASC-H, and there was a statistically significant association (p = 0.0341). A positive HR-HPV test was associated with ASC-H (p = 0.0075). Conclusion The data suggest that even for a population of Brazilian women assisted at private clinics, the national guidelines recommendations for ASCs results are not followed.
Resumo Objetivo Avaliar a conduta adotada por ginecologistas após resultados citológicos apresentando células escamosas atípicas (ASCs) e os desfechos destes casos em mulheres brasileiras. Métodos Um estudo observacional prospectivo avaliou o manejo clínico inicial do ginecologista nos casos de 2.458 resultados citológicos apresentando ASCs coletados entre janeiro de 2010 e julho de 2016. Os respectivos desfechos citológicos, histológicos e de detecção do papilomavírus humano (HPV) foram comparados entre os subgrupos células escamosas atípicas de significado indeterminado (ASC-US) e células escamosas atípicas não podendo excluir lesão intraepitelial de alto grau (ASC-H). Resultados Nenhuma conduta foi adotada em 36,97% de citologias do tipo ASC-US e 40,5% do tipo ASC-H. A conduta mais escolhida foi a repetição da citologia, inclusive para acompanhamento de ASC-H, o que contraria as diretrizes nacionais. O tempo de realização de uma nova citologia para resultado do tipo ASC-US em mulheres com mais de 30 anos de idade foi de 13,03 meses, também em desacordo com as diretrizes (p< 0,0001). Resultados negativos para lesão intraepitelial ou neoplasia maligna (NILM), tanto citológicos (p = 0,0026) como histológicos (p = 0,0017), foram associados a ASC-US, enquanto que resultados negativos para lesões intraepiteliais escamosas de alto grau (HSILs), citológicos (p< 0,0001) e histológicos, foram associados a ASC-H (p< 0,0001). Dois carcinomas cervicais invasivos foram encontrados durante o acompanhamento para ASC-H e uma associação estatisticamente significante foi estabelecida (p = 0,0341). Um teste de HR-HPV positivo foi associado a ASC-H (p = 0,0075). Conclusão Os dados sugerem que mesmo para uma população de mulheres brasileiras atendidas em clínicas privadas, as recomendações das diretrizes clínicas nacionais para resultados citológicos apresentando ASCs não são seguidas.

OBJECTIVE: Knowledge regarding the prevalence and distribution of human papillomavirus (HPV) genotyping in healthy women is important in establishing strategies for cervical cancer screening and HPV vaccination. METHODS: A total of 18,170 women who visited a Korean Medical Institute for health check-ups were recruited retrospectively; they underwent HPV genotyping and conventional cervical cytology. An HPV DNA test was performed using the Anyplex™ II HPV 28 detection system (Seegene) or HPV Liquid Bead Microarray (Osang Healthcare). The distribution of HPV genotypes was assessed according to cervical cytology and age. RESULTS: HPV was detected in 3,037 (16.71%) of the 18,170 women enrolled, and 2,268 (12.48%) were positive for high-risk (HR) HPV. In total, HPV 53 (9.69% of all detected HPV viruses) was the most common type; HPV 58 (7.90%) and 52 (7.81%) were also common. HPV 54 (6.99%) was common in low-risk subjects. Overall and in the normal cytology group, the most common HPV genotype was HPV 53, whereas HPV 58 was more common in women who had atypical squamous cells of undetermined significance or low-grade squamous intraepithelial neoplasia cervical cytology. In addition, HPV 16 was the most common type in cases with high-grade squamous intraepithelial neoplasia (HSIL)/atypical squamous cells-cannot exclude HSIL. Among women with normal cytology, 76 of 231 (32.9%) women under 24 years of age were positive for HR HPV, whereas 84 of 852 (9.9%) women aged 55–59 years were positive. CONCLUSION: HPV 53 was the most prevalent genotype in healthy women. Distribution of HPV genotypes varied with cervical cytology and age. Our study provides important baseline data for the recently implemented national HPV vaccination program.

OBJECTIVE: This study aimed to determine the factors affecting pathologic discrepancy and final diagnosis between colposcopic biopsy and pathology by loop electrosurgical excision procedure (LEEP). METHODS: Between 2004 and 2016, 1,200 patients who underwent LEEP were enrolled for this study. 667 underwent cervical cytology, human papillomavirus (HPV) test, colposcopic biopsy, and LEEP. We analyzed patient's age, menopausal status, number of delivery, abortion times, cervical cytology, number of punch biopsies, HPV type, LEEP, and interval between colposcopic biopsy and LEEP. RESULTS: Logistic regression analysis of the final diagnosis showed that age 30–39 years and other high HPV group types were associated with cancer diagnosis, whereas atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (ASC-H), high-grade squamous intraepithelial lesion (HSIL), and HPV type 16 affected the diagnosis of cervical intraepithelial neoplasia (CIN) 2. The overall concordance rate of histopathology between punch biopsy and LEEP was 43.3%. The rates of detecting a more severe lesion by LEEP than those by biopsy were 23.1%. The rates of a less severe lesion detected by LEEP than those by biopsy were 33.6%. Factors related with biopsy underestimation were as follows: < 1 vaginal delivery, HSIL, number of punch biopsies and HPV type. Punch biopsy number is a unique factor of biopsy overestimation. CONCLUSION: Patients with ASC-H, HSIL, and HPV type 16 may undergo conization immediately without colposcopic biopsy. We suggest that colposcopically directed 3 to 5 punch biopsies may be used to determine the need for conization.

PURPOSE: This study aimed to evaluate the performance of the PANArray human papilloma virus (HPV) test, a PCR-based DNA microarray assay, in detecting HPV from patient samples and its concordance with the cobas 4800 HPV and Hybrid Capture 2 (HC2) tests. MATERIALS AND METHODS: The PANArray HPV, cobas 4800 HPV, and HC2 tests were performed on 504 cervical swab samples from patients with atypical cells of undetermined significance at five hospitals. The samples that were interpreted as ‘HPV-other’ type positive in the PANArray HPV test were confirmed by direct sequencing. RESULTS: The concordance rates were 80.8% between the cobas 4800 HPV and PANArray HPV tests [κ=0.59, 95% confidence interval (CI) 0.52–0.66] and 80.2% (κ=0.6, 95% CI 0.55–0.68) between the HC2 and PANArray HPV tests. Among the 62 patients negative on PANArray HPV (defined as the absence of high risk HPV), but positive on both cobas 4800 HPV and HC2 tests, 42 (67.7%) tested positive for ‘HPV-other’ types on the PANArray HPV test, and 31 (50.0%) had gray zone results [relative light unit/control (RLU/CO), 1.4–9.25] in the HC2 test. Of the patients deemed positive by the PANArray HPV test, 43 tested positive for high-risk (HR) HPV in cobas 4800 HPV and HC 2 tests. Among them, 58.2% showed HR HPV, including HPV 16, by direct sequencing, of which 25% had gray results. CONCLUSION: Results classified as ‘HPV-other’ type by the PANArray HPV test, or gray zone results by HC2 (RLU/CO ratio level 1–10) should be carefully interpreted using comprehensive clinical information.

OBJECTIVE: To investigate the progression risk of atypical squamous cells of undetermined significance (ASCUS) with different clinical managements. METHODS: Women with their first diagnosis of ASCUS cytology were retrieved from the national cervical cancer screening database and linked to the national health insurance research database to identify the management of these women. The incidences of developing cervical intraepithelial neoplasia grade 3 and invasive cervical cancer (CIN3+) were calculated, and the hazard ratios (HRs) were estimated using a Cox proportional hazards model. This study was approved by the Research Ethics Committee of the National Taiwan University Hospital and is registered at ClinicalTrials.gov (Identifier: NCT02063152). RESULTS: There were total 69,741 women included. Various management strategies including colposcopy, cervical biopsies and/or endocervical curettage, and cryotherapy, failed to reduce the risk of subsequent CIN3+ compared with repeat cervical smears. Loop electrosurgical excision procedure/conization significantly decreased risk of subsequent CIN3+ lesions (HR=0.22; 95% confidence interval [CI]=0.07–0.68; p=0.010). Women in their 40s–50s had an approximately 30% risk reduction compared to other age groups. Women with a previous screening history >5 years from the present ASCUS diagnosis were at increased risk for CIN3+ (HR=1.24; 95% CI=1.03–1.49; p=0.020). CONCLUSION: In women of first-time ASCUS cytology, a program of repeat cytology can be an acceptable clinical option in low-resource settings. Caution should be taken especially in women with remote cervical screening history more than 5 years.

OBJECTIVE: To assess the burden of cervical neoplasia in mid-western rural, Nepal using cytology, visual inspection with acetic acid (VIA) and visual inspection with Lugol's iodine (VILI). METHOD: A cross-sectional, population-based study was conducted. Total of 2,279 married, non-pregnant women aged 20–65 years participated in a screening clinic from May 2016 to January 2017. All eligible women completed self-report of socio-demographic and reproductive health data followed by screening tests. Biopsies were obtained from areas on the cervix assessed by VIA and or VILI to be abnormal. Final disease was confirmed by biopsy report. RESULTS: A total of 96.09% (n=2,190) women were eligible for this study with mean age 32.78±9.33 years. The overall rate of positive cytology, VIA, and VILI were 3.69%, 12.45%, and 16.89%, respectively. Sixty-two cases were biopsy proven cervical neoplasia. Altogether 78 (3.69%) cases were cytologically abnormal: 25 (1.18%) were atypical squamous cells of undetermined significance, 33 (1.56%) were low-grade squamous intraepithelial lesion, 11 (0.52%) were high-grade squamous intraepithelial lesion, and 9 (0.42%) were squamous cell carcinoma. Illiterate women appeared to be at higher risk for cervical neoplasia (p < 0.001). Similarly, age ≥ 46 years (p < 0.013), participant's multiple marriages or sexual partners (p < 0.005), and positive human immunodeficiency virus status (p < 0.001) were significantly associated with abnormal cytology. CONCLUSION: Based on cytology report, there is 3.69% prevalence of cervical neoplasia among women in a rural region of mid-western, Nepal. A “screen and treat” approach would be more attractive in low resource settings.

OBJECTIVE: This study was to identify the risk factors for cytological progression in women with atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesions (LSIL). METHODS: We analyzed data from women infected with the human papillomavirus (HPV) who participated in the Korean HPV cohort study. The cohort recruited women aged 20–60 years with abnormal cervical cytology (ASC-US or LSIL) from April 2010. All women were followed-up at every 6-month intervals with cervical cytology and HPV DNA testing. RESULTS: Of the 1,158 women included, 654 (56.5%) and 504 (43.5%) women showed ASC-US and LSIL, respectively. At the time of enrollment, 143 women tested positive for HPV 16 (85 single and 58 multiple infections). Cervical cytology performed in the HPV 16-positive women showed progression in 27%, no change in 23%, and regression in 50% of the women at the six-month follow-up. The progression rate associated with HPV 16 infection was higher than that with infection caused by other HPV types (relative risk [RR], 1.75; 95% confidence interval [CI], 1.08–2.84; P=0.028). The cytological progression rate in women with persistent HPV 16 infection was higher than that in women with incidental or cleared infections (P < 0.001). Logistic regression analysis showed a significant relationship between cigarette smoking and cytological progression (RR, 4.15; 95% CI, 1.01–17.00). CONCLUSION: The cytological progression rate in HPV 16-positive women with ASC-US or LSIL is higher than that in women infected with other HPV types. Additionally, cigarette smoking may play a role in cytological progression.
