Prevalencia y factores asociados al tamizaje preventivo del cáncer cervical en una región de Perú / Prevalence and factors associated with cervical cancer preventive screening in a Peruvian region

Introducción El tamizaje preventivo del cáncer cervical es la mejor estrategia disponible para mermar la incidencia y mortalidad por esta neoplasia. No obstante, la baja proporción de mujeres que se someten al tamizaje de rutina, constituye un problema pendiente para los sistemas de salud del mundo Objetivo Estimar la prevalencia y los factores asociados a realizarse el tamizaje preventivo del cáncer cervical en una región de Perú Métodos Estudio transversal y multicéntrico. En él participaron 1146 mujeres usuarias de centros de salud de una región sanitaria de Perú. La variable dependiente fue la realización de un tamizaje preventivo de cáncer cervical con Papanicolaou o inspección visual con ácido acético, en los últimos dos años. Las variables independientes fueron factores sociodemográficos, sociosanitarios, conocimientos sobre cáncer de cuello uterino y virus del papiloma humano, actitudes e información ante las pruebas de tamizaje. Para evaluar la asociación entre las variables se calcularon razones de prevalencia crudas y ajustadas, con modelos lineales generalizados de la familia Poisson. Resultados La prevalencia general del tamizaje preventivo fue de 50,5%. Esta se asoció a realizarse la prueba, el grado de instrucción superior y área de residencia urbana, usar métodos anticonceptivos, tener seguro de salud, recibir recomendación del personal de salud para realizarse el tamizaje y sentirse preocupada por adquirir cáncer de cuello uterino. También se vinculó a quienes respondieron que el cáncer es prevenible, que habían oído hablar de cáncer cervicouterino o virus del papiloma humano y si cree que este virus puede causar cáncer de cuello uterino, Además, se asoció el admitir que existe posibilidad de curar el cáncer con su detección temprana. En cambio, el considerar riesgoso el tamizaje preventivo se relacionó con no realizarse la prueba. Conclusiones La proporción de mujeres con tamizaje preventivo de cáncer cervical es baja. Asimismo, se identificaron ciertos factores asociados modificables, los que podrían mejorar las conductas y tasas del tamizaje preventivo

Introduction Preventive screening for cervical cancer is the best available strategy to reduce the incidence and mortality from this neoplasm. However, the low proportion of women who undergo routine screening is a pending concern for healthcare systems worldwide. Objective To estimate the prevalence and factors associated with preventive cervical cancer screening in a Peruvian region. Methods Cross-sectional, multicenter study. It enrolled 1146 women users of healthcare centers in a Peruvian sanitary region. The dependent variable was the performance of cervical cancer preventive screening with Papanicolaou or visual inspection with acetic acid in the last two years. The independent variables were sociodemographic and socio-sanitary factors, knowledge about cervical cancer and human papillomavirus, attitudes and information towards screening tests. To evaluate the association between the variables, crude and adjusted prevalence ratios were calculated with generalized linear models of Poisson. Results The overall prevalence of preventive screening was 50.5%. This was associated with being tested, having a higher education level and urban area of residence, using contraceptive methods, having health insurance, being recommended by healthcare personnel to be screened, and being concerned about developing cervical cancer. It was also associated with responding that this cancer is preventable, being aware of cervical cancer or human papillomavirus, and believing it can cause cervical cancer. In contrast, considering preventive screening risky was associated with not having the test. Conclusions The proportion of women with preventive cervical cancer screening is low. In addition, certain associated modifiable factors were identified, which could improve preventive screening behaviors and rates.

Neoplasia cervical e infección por virus del papiloma humano como factores de riesgo para desarrollo de cáncer anal y lesiones precursoras / Cervical neoplasia and human papilloma virus infection as risk factors for the development of anal cancer and precursor lesions

RESUMEN La incidencia del cáncer anal ha presentado un incremento en los últimos 10 años, sobre todo en población considerada vulnerable. Las mujeres con antecedentes de infección por Virus del Papiloma Humano (VPH) en el tracto genital, tienen mayor riesgo de este tipo de cáncer. Se ha demostrado que, la infección con genotipos de VPH de alto riesgo (AR), en la región anogenital, desempeña un papel en la etiopatogenia de dicho cáncer. Se desconocen muchos aspectos de la historia natural de las lesiones anales, pero se considera que la zona de transición anal presenta un alto recambio celular, por lo que se ha planteado un mecanismo fisiopatológico de infección por VPH-AR y desarrollo de lesiones invasoras, similar al del cáncer cervical. El objetivo de este trabajo fue mostrar el estado actual sobre la información epidemiológica que vincula el riesgo de desarrollar cáncer anal en mujeres con lesiones precursoras de cáncer cervical asociadas a la infección por VPH. La relevancia de dicha información es proporcionar una base de recomendaciones para la detección oportuna de cáncer anal en mujeres consideradas de AR de padecerlo y, favorecer la realización de estudios prospectivos en la población.

ABSTRACT The incidence of anal cancer has increased in the last 10 years, especially in the population considered to be at risk. Women with a history of infection in the genital tract by Human Papillomavirus (HPV) have higher risk of developing this type of cancer. The presence of high-risk (HR) HPV genotypes in the anogenital region has been shown to play a role in the etiopathogenesis of anal cancer. Many aspects of the natural history of anal lesions are unknown, but the anal transition zone is considered to have a high cell replacement. This is why a pathophysiological mechanism of HR-HPV infection and development of invasive lesions similar to those of cervical cancer has been suggested. The aim of this work was to show the current status of the epidemiological information that links the risk of developing anal cancer in women with cervical cancer precursor lesions associated with HPV infection. The relevance of this information is to provide a basis of recommendations for the timely detection of anal cancer in women considered to be at HR of suffering it, and to encourage more prospective studies in this population.

Preventing Uterine Cervix Cancer: The Clinical Meaning of Atypical Glandular Cells / Prevenção do câncer do colo uterino: Significado clínico das células glandulares atípicas

Abstract Objective To determine the prevalence of the atypical glandular cells (AGCs) cytology and to analyze its clinical significance in different age ranges. Methods Retrospective observational study using computerized data from the Brazilian National Cancer Institute, including women screened between January 2002 and December 2008. The women included were those with an AGC result who were properly followed-up with colposcopy and a second cytology. Results A total of 132,147 cytopathological exams were performed during the study period. Five-hundred and thirty-three (0.4%) women with AGC cytology were identified and, of these, 69.41% (370/533) were properly referred for colposcopy and a new cytology. Most of the women (79.2%) with a 1st or 2nd AGC cytology were between the ages of 25 and 54 years. The 2nd cytology demonstrated 67.6% (250/370) of normality, 24.5% (91/370) of squamous atypia, and 6.2% (23/370) of AGC, 0.8% (3/370) adenocarcinoma in situ and 0.8% (3/370) adenocarcinoma invasor. On biopsy of the women with a second AGC cytology, 43.4% (10/23) had normal histology, 43.4% (10/23) had squamous lesions, 8.7% (2/23) had invasive adenocarcinoma, and 1.2% (1/23) had an inconclusive report. All of the women with high-grade squamous intraepithelial lesion (HSIL) or invasive adenocarcinoma (respectively 5 and 2 patients), after a 2nd AGC cytology were 25 years old or older. Conclusion The prevalence of the AGC cytology was low in the studied population. Most of the AGC cytology cases occurred in adult women between the ages of 25 and 54. Although most of the patients had normal histology after follow-up, several of them presented with squamous intraepithelial lesions or invasive adenocarcinoma.

Resumo Objetivo Determinar a prevalência de citologia com laudo de células glandulares atípicas (AGCs, na sigla em inglês) e analisar a significância clínica nas diferentes faixas etárias Métodos Estudo observacional retrospectivo, usando os dados arquivados no sistema do Instituto Nacional de Câncer no Brasil, que incluiu mulheres rastreadas entre janeiro de 2002 a dezembro de 2008. As mulheres incluídas tinham citologia com resultado de AGCs, que foram acompanhadas com colposcopia e nova citologia Resultados Um total de132,147 exames citopatológicos foram incluídos durante o período de estudo. Quinhentas e trinta e três mulheres com citologia de AGC foram identificadas e destas, 69.41% (370) foram encaminhadas para colposcopia e nova citologia. A prevalência de citologia de AGC na população estudada foi 0.4%. A maioria das mulheres (79.22%) com resultado citológico de AGC tinham idade entre 25 e 54 anos. A segunda citologia demonstrou 67.56% (250/370) de normalidade, 24.5% (91/370) de atipias escamosas, e 6.2% (23/370) de AGC. Na biopsia das mulheres com a 2ª citologia de AGC, 43.4% (10/23) tinham histologia normal, 43.4% (10/23) tinha lesões escamosas, 8.7% (2/23) tinha adenocarcinoma invasor e 1.2% (1/23) tinha laudo inconclusivo. Todas as mulheres com lesões intraepiteliais escamosas de alto grau (HSIL, na sigla em inglês) ou adenocarcinoma invasor (respectivamente 5 e 2pacientes), após a 2ª citologia com AGC, tinham 25 anos de idade ou mais. Conclusão A prevalência de citologia com AGC foi baixa na população estudada. Muitos casos de citologia com AGC apareceram em mulheres adultas, entre 25 e 54 anos de idade. Embora a maioria das pacientes tiveram histologia normal após seguimento, várias apresentaram lesões intraepiteliais escamosas ou glandulares invasoras.

Analysis of the Excess of Papanicolaou Tests in Brazil from 2006 to 2015 / Análise do excesso de testes de Papanicolaou no Brasil entre 2006 e 2015

Abstract Objective To analyze the quantity of cervical smears, also designated Papanicolaou tests, between 2006 and 2015 in all the Federal units of Brazil, as well as to verify the quantity of exams collected outside the recommended age range and the economic impact of such excess. Methods The data was collected from the Ministry of Health's database called Sistema de Informação do Câncer do Colo de Útero (SISCOLO), which contains all the test results collected nationwide by the Unified Health System (SUS, in the Portuguese acronym). From that, the number of exams and the age range of thewomen who underwent them were analyzed; besides, these numbers were stratified according to the state of where the exam was performed. The quantity of exams collected outside the recommended age range was verified, and, so, the economic impact generated was noted. Results Between 2006and2015, 87,425,549Papanicolaoutestswere collected in Brazil. Of these, 20,215,052 testswere collected outside the age range recommended by the Brazilian Ministry of Health; this number corresponded to 23.12% of all exams. From such data, considering that each Pap smear collected by SUS generates a cost of BRL 7.30 to the government, according to the information in the Tabela SUS dated September 2018, there was a total charge of BRL 147,569,880 for tests collected outside the protocol. Conclusion In Brazil, according to the Ministry of Health's protocol about the recommended practices on collecting Pap smears, whose newest edition dates of 2016, it is recommended that Pap smears are collected inwomen from a specific age range, inwhom the potential diagnosing advantages overcome the onus of overdiagnosis or of a lesion with great regression potential. However, such protocols have not been correctly followed, promoting more than 20 million tests in excess, and an exorbitant cost for the Brazilian public health system. It is relevant to take measures to correctly use the official protocol, reducing the patients risks, as well as the economic impact for SUS.

Resumo Objetivo Analisar a quantidade de exames cérvico-vaginais, também chamados de Teste de Papanicolau, entre os anos de 2006 e 2015 em todos os estados brasileiros, bem como verificar o número de exames realizados fora da faixa etária indicada, e o impacto econômico desse excesso. Métodos Os dados foram coletados a partir da base de dados do Ministério da Saúde chamada Sistema de Informação do Câncer do Colo de Útero (SISCOLO), que reúne os resultados de exames realizados em todo o Brasil pelo sistema único de saúde (SUS). A partir disso, foi analisado o número de exames e a faixa-etária de realização dos mesmos; além disso, esses números foram estratificados de acordo com o estado brasileiro de origem do exame. Foi verificada a quantidade de exames fora da idade recomendada, e, assim, foi observado o impacto econômico gerado. Resultado Entre 2006 e 2015, 87.425.549 exames de Papanicolau foram realizados no Brasil. Deste montante, 20.215.052 testes foram realizados fora da faixa-etária preconizada pelo Ministério da Saúde do Brasil, o que equivale a 23,12% do total. A partir desse número, considerando que cada exame cérvico -vaginal realizado pelo SUS gera um custo de R$ 7,30 para o governo, de acordo com informações na Tabela SUS datada de setembro de 2018, foram gastos R$ 147.569.880 em exames realizados sem indicação. Conclusão No Brasil, no protocolo do Ministério da Saúde sobre as práticas adequadas em coleta de exames cérvico-vaginais, sendo sua edição mais recente de 2016, a recomendação é realizar o teste de Papanicolau em mulheres dentro de uma faixaetária específica, na qual a chance de se diagnosticar uma lesão supera o ônus de um sobrediagnóstico ou uma lesão com grande potencial de regressão. Entretanto, essa recomendação não tem sido seguida corretamente, gerando mais de 20 milhões de exames excedentes e umcusto monetário exorbitante para o sistema público de saúde. É importante que medidas sejam tomadas para que o protocolo seja empregado corretamente a fim de reduzir riscos para a paciente, bem como a redução de gastos desnecessários para o SUS.

The prevalence of intraepithelial lesions in preventive examinations carried out in the "legal amazon" region

Introduction: Cervical cancer is a public health problem, and tracking of the disease must follow a set of organized programmed actions, with populations and periodicity defined. Objective: Identifying the prevalence of intraepithelial lesions in preventive examinations performed in the municipality of Sinop-MT between 2010 and 2013. Methods: Statistical data obtained using the DATASUS/SISCOLO system were used. Results: When considering the descriptive diagnosis for cellular alterations, 412 and 167 altered exams with low- and high-grade intraepithelial lesions (respectively) were found. The prevalence of both low-grade (25.45%) and high-grade (10.32%) intraepithelial lesions were higher outside of the recommended age range (25-64 years). Conclusions: Studies on the prevention of cervical cancer are extremely relevant in order to analyze the coverage of screening in areas served by basic health units and to understand the factors associated with non-adherence of women to preventive examination. It is noteworthy that during the time period analyzed, women in the municipality of Sinop did not fulfill the municipal goal.(AU)

Introdução: O câncer do colo do útero é um problema de saúde pública e o rastreamento dessa doença deve seguir um conjunto de ações programadas, organizadas com populações e periodicidade definidas. Objetivo: este estudo teve como objetivo identificar a prevalência da lesão intraepitelial em exames preventivos coletados no município de Sinop-MT, entre 2010 e 2013. Métodos: Estudo retrospectivo realizado no Município de Sinop. Os dados utilizados foram obtidos por meio do sistema DATASUS/SISCOLO, entre 2010 e 2013. As variáveis analisadas foram: número de exames citopatológicos dentro dos limites de normalidade, lesão intraepitelial de baixo grau (LIBG) e lesão intraepitelial de alto grau (LIAG) e faixa etária de 25 a 64 anos. Resultados: ao considerar o diagnóstico descritivo para alterações celulares, foram constatados 412 e 167 exames alterados com lesão intraepitelial de baixo e alto grau, respectivamente. Tanto a prevalência de lesão intraepitelial de baixo grau (25,45%), quanto de alto grau (10,32%), foram maiores fora da faixa etária preconizada (25 a 64 anos). Portanto, estudos sobre a prevenção do câncer do colo do útero são de extrema relevância, a fim de analisar a cobertura do rastreamento em áreas atendidas pelas unidades básicas de saúde e compreender os fatores associados à não adesão das mulheres à realização do exame preventivo. Conclusão: Ressalta-se que o município de Sinop nos quatros anos analisados não cumpriu a meta municipal.(AU)

Immunohistochemical WWOX expression and association with angiogenesis, p53 expression, cell proliferation and clinicopathological parameters in cervical cancer / Avaliação da expressão do gene WWOX por avaliação imunohistoquímica, sua associação com marcador de angiogênese, expressão do p53, proliferação celular e parâmetros clinicopatológicos no câncer de colo uterino

Abstract Objective The current study evaluated the expression of WW domain-containing oxidoreductase (WWOX), its association with clinicopathological features and with p53, Ki-67 (cell proliferation) and CD31 (angiogenesis) expression in patients with invasive cervical squamous cell carcinoma (ICSCC). To the best of our knowledge, no other study has evaluated this association. Methods Women with IB stage-ICSCC (n = 20) and women with uterine leiomyoma (n = 20) were prospectively evaluated. Patients with ICSCC were submitted to type BC1 radical hysterectomy and pelvic lymphadenectomy. Patients in the control group underwent vaginal hysterectomy. Tissue samples were stained with hematoxylin and eosin for histological evaluation and protein expression was detected by immunohistochemistry studies. Results The WWOX expression was significantly lower in the tumor compared with the expression in thebenign cervix (p = 0.019). TheWWOXexpressionwas inversely associated with the CD31 expression in the tumor samples (p = 0.018). There was no association betweentheWWOXexpression with the p53 expression (p = 0.464)or the Ki-67expression (p = 0.360) in the samples of invasive carcinoma of the cervix. There was no association between the WWOX expression and tumor size (p = 0.156), grade of differentiation (p = 0.914), presence of lymphatic vascular invasion (p = 0.155), parametrium involvement (p = 0.421) or pelvic lymph node metastasis (p = 0.310) in ICSCC tissue samples. Conclusion The results suggested that WWOX may be involved in ICSCC carcinogenesis, and this marker was associated with tumor angiogenesis.

Resumo Objetivo O presente estudo avaliou a expressão do WWOX, sua associação com características clinicopatológicas e com a expressão do p53, ki-67 (proliferação celular) e CD31 (angiogênese) em pacientes com carcinoma invasivo de células escamosas do colo uterino, ou simplesmente câncer do colo uterino (CCE). Métodos Foram avaliadas prospectivamente pacientes com CCE no estágio IB (n = 20) e mulheres com mioma uterino, no grupo controle (n = 20). As pacientes com CCE foram submetidas à histerectomia radical e à linfadenectomia pélvica do tipo B-C1. As mulheres no grupo-controle foram submetidas à histerectomia vaginal. As amostras de tecido foramcoradas comhematoxilina e eosina para avaliação histológica e a expressão das proteínas foi detectada por imuno-histoquímico. Resultados A expressão do WWOX foi significativamente menor no tumor quando comparada com sua expressão no colo do útero benigno (p = 0,019). A expressão tumoral de CD31 foi inversamente associada à expressão de WWOX (p = 0,018). Sua expressão não foi associada à expressão tumoral de p53 e Ki-67 em pacientes com CCE (p = 0,464 e p = 0,360, respectivamente). Não houve associação entre a expressão de WWOX e o tamanho do tumor (p = 0,156), grau de diferenciação (p = 0,914), presença de invasão vascular linfática (p = 0,155), comprometimento do paramétrio (p = 0,421) ou metástase dos linfonodos pélvicos (p = 0,310) em pacientes com CCE. Conclusão Os resultados sugeriram que o WWOX pode estar envolvido na carcinogênese do CICECU e esse marcador foi associado à angiogênese tumoral.

The value of diffusion kurtosis imaging in evaluating pathological grade of cervical squamous cell carcinoma / 实用放射学杂志

Objective To investigate the value of diffusion kurtosis imaging (DKI)quantitative parameters in evaluating patholog-ical grade of cervical squamous cell carcinoma (CSCC).Methods The DKI images of 45 patients with CSCC were analyzed retrospec-tively.According to the results of pathology,22 cases were divided into poorly differentiated group and 23 cases well-moderately dif-ferentiated group.The DKI parameters of two groups were measured by two observers,which included mean kurtosis (MK),axial kurtosis (Ka),radial kurtosis (Kr),fractional anisotropy of kurtosis (FAk),mean diffusivity (MD),axial diffusivity (Da),radial diffusivity (Dr)and fractional anisotropy (FA).The intra-class correlation coefficients (ICC)was used to test the consistency of the parameters measured results on two observers.The two independent samples t test was used to compare the parameters of two groups,and the ROC curve was used to evaluate the effectiveness of each parameter in order to evaluate the poorly differentiated CSCC and find the boundary values.Results The data consistency of two observers were good (ICC>0.75).The MK,Ka and Kr values on poorly differentiated CSCC were greater than that on well-moderately differentiated (P0.05).Thearea un-der curve (AUC)of MK,Ka,Kr,MD,Da and Dr values to diagnose poorly differentiated CSCC were 0.914,0.831,0.865,0.850, 0.778 and 0.865,respectively.The boundary values of diagnosing poorly differentiated CSCC were MK≥0.973,Ka≥1.075,Kr≥0.823, MD≤0.974μm2/ms,Da≤1.185μm2/ms and Dr≤0.762μm2/ms,respectively.Conclusion DKI can effectively predict the patho-logical grading of CSCC,which has a good clinical application prospects.

Immunohistochemical study of p53 expression as proliferative index in neoplasia of the uterine cervix

Introduction: Cervical cancer is the third most common cancer in India. In women, it is the second most common after breast carcinoma. Human cancers arise from a protracted sequence of multiple genetic and epigenetic alterations which involve the growth regulatory genes like p53. Aim: This study aimed at correlation of immunopositivity of p53 with the histopathological type and grade of carcinoma cervix. Materials and Methods: A total of 100 cases of cervical biopsy/ hysterectomy specimens of carcinoma cervix received at the Department of Pathology, SMSMC Jaipur from January 2016 to September 2017 were examined for gross and microscopic features. Immunohistochemistry was used to study the p53 expression as proliferative index in cervical intraepithelial neoplasia, invasive squamous cell carcinoma as well as adenocarcinoma of the uterine cervix. Results: The demographic profile of SCC and CIN in this study was in concordance with that described by epidemiological studies in India with larger group of patients presenting with advanced stage tumors. Increased expression of p53 was found in increasing grades of CIN and SCC. The p53 positivity showed a statistically significant association with squamous cell carcinoma (SCC) histologic type (P = 0.005). Conclusion: The expression of p53 is greater in the malignant cervical neoplasms than pre-malignant cervical lesions, suggesting that p53 overexpression can be used as an early diagnostic tool and also as a prognostic indicator.

Barreras para la prevención y detección temprana de cáncer de cuello uterino / Barriers to prevention and early detection of cervical cancer

Objetivo: Identificar las barreras para la detección temprana del cáncer de cuello uterino. Método: Revisión integrativa de literatura, en bases de datos como Science Direct, Medline, SciELO y Scopus, publicados durante los últimos seis años, escritos en inglés, portugués y español. Resultados: Los aspectos socioculturales, las estrategias de prevención empleadas y la dificultad para acceder a la atención fueron las barreras encontradas en la revisión; igualmente, la poca aceptación de la vacuna contra el virus del papiloma humano y la no asistencia a la citología cérvico-vaginal inciden en la aparición de numerosos casos de lesiones preneoplásicas. Conclusiones: Se evidencia la necesidad de fortalecer las acciones de educación, información y abogacía del profesional de enfermería, que contribuyan a reducir la incidencia de esta patología, lo cual representa un reto importante para el personal de salud.

Objective: To identify the barriers to early detection of cervical cancer. Method: Integrative literature review in databases such as Science Direct, Medline, SciELO and Scopus, published during the past six years, written in English, Portuguese and Spanish. Results: Socio-cultural aspects, prevention strategies employed and the difficulty in accessing care barriers were found in the review; also, the lack of acceptance of HPV vaccines and non-attendance to Pap test affect the appearance of numerous cases of pre-neoplastic lesions. Conclusions: It is evident that there is a need to strengthen actions of education, information and support to nursing professionals, to help reduce the incidence of this disease, which represents an important challenge to health care personnel.

Histerectomia radical laparoscópica versus laparotomia no tratamento do câncer inicial do colo uterino / Radical hysterectomy by laparoscopy v by laparotomy for the treatment of early cervical cancer

O tratamento cirúrgico padrão para o câncer do colo do útero em estádio inicial é a histerectomia radical abdominal (HRA). Nos últimos anos, os avanços na cirurgia minimamente invasiva tornaram possível a realização de histerectomia radical com o uso da laparoscopia, com objetivo de reduzir a morbidade cirúrgica e promover uma recuperação mais rápida. Esta revisão compara a eficácia e a segurança da histerectomia laparoscópica (HRL) com a HRA em mulheres com estádios iniciais (I até IIa) do câncer de colo uterino. Fez-se a busca da literatura através de pesquisa na base de dados do MEDLINE/PubMed, LILACS, SciELO e Cochrane Library entre 2010 - 2015, com as palavras-chave: histerectomia, histerectomia laparoscópica, laparoscopia laparotomia, câncer cervical precoce. Foi constatado que a HRL está associada à menor morbidade cirúrgica em termos de perda sanguínea intraoperatória e menor permanência hospitalar quando comparada com a HRA. No entanto, estudos multicêntricos randomizados são necessários para que se tenha dados definitivos sobre a sobrevida global e livre de doença.(AU)

Standard surgical management for selected early-stage cervical cancer is radical abdominal hysterectomy (HRA). In recent years, advances in minimal access surgery have made it possible to perform radical hysterectomy with the use of laparoscopy with the aim of reducing the surgical morbidity and promoting a faster recovery. This review compares the effectiveness and safety of laparoscopically (HRL) with a radical abdominal hysterectomy (HRA) in women with cervical cancer in early-stage (I to IIa). The literature review was performed using MEDLINE/PubMed, LILACS, SciELO e Cochrane Library for articles published between 2010 and 2015, and the keywords: hysterectomy, hysterectomy laparoscopic, laparoscopy, laparotomy, cervical cancer in early stages. When compared with HRA the HRL was associated with lower surgical morbidity, in terms of intraoperative blood loss and shorter hospital permanence. However, multicenter and randomized studies are needed for definitive data on overall survival and disease-free survival.(AU)

Comparison of Classical and Secondary Cytologic Criteria Relative to Hybrid Capture for Diagnosing Cervical-vaginal Infection by Human Papillomavirus / Comparação entre os critérios citológicos clássicos e secundários para o diagnóstico de infecção cérvico-vaginal por papiloma vírus humano em relação à captura híbrida

Objective To compare the diagnostic accuracy of the classic Meisels cytologic criteria and the Schneider secondary criteria relative to the hybrid capture method for diagnosing HPV infection. Methods This was a retrospective study performed at a public university hospital. A total of 41 patients with a cytologic diagnosis of HPV infection and 40 HPV-negative patients were selected for review of the cervical-vaginal smears seeking to classical and secondary criteria. A single pathologist reviewed the slides in search of the criteria. The classical and secondary cytologic criteria were compared with the hybrid capture for diagnosing HPV infection. Bartleti test was applied for the age analysis, and Fisher's exact test was used to compare proportions. The tests were considered significant when the probability of rejecting the null hypothesis was less than 5% (p < 0.05). Results The Meisels criteria were less sensitive (34.0%) than the secondary Schneider criteria (57.5%) when compared with the hybrid capture (p < 0.0001), although the specificity of the former criteria was non-significantly higher (91.2% and 67.7%, respectively). In cases of moderate or intense inflammation, the sensitivity and specificity of the Schneider criteria were decreased, 33.3% and 50.0% respectively (p = 0.0115). Conclusions Compared with hybrid capture for diagnosis of HPV infection, the sensitivity of the secondary Schneider criteria was higher than the classical Meisels criteria.Moderate or intense inflammation reduces the sensitivity and specificity of the secondary Schneider criteria for diagnosing HPV infection using the hybrid capture as the gold standard.

Objetivo Comparar a acurácia diagnóstica dos critérios citológicos clássicos de Meisels com a dos critérios secundários de Schneider em relação a captura híbrida para o diagnóstico de infecção pelo HPV. Métodos Trata-se de estudo retrospectivo realizado em hospital público universitário. Quarenta e uma pacientes com diagnóstico citológico de infecção pelo HPV e 40 pacientes HPV-negativas foram selecionadas para avaliação dos esfregaços cervicaisvaginais em busca dos critérios clássicos e secundários. Um único patologista reviu as lâminas. Os critérios citológicos clássicos e secundários foram comparados com a captura híbrida para o diagnóstico de infecção pelo HPV. O teste de Bartleti foi aplicado para a análise das idades e o teste exato de Fisher para comparar proporções. Os testes foram considerados significativos quando a probabilidade de rejeitar a hipótese de nulidade foi menor que 5% (p < 0,05). Resultados Os critérios deMeisels forammenos sensíveis (34,0%) que os secundários de Schneider (57,5%) quando comparados com a captura híbrida (p < 0,0001), embora a especificidade dos critérios de Meisels não tenha sido significativamente superior (91,2% e 67,7%, respectivamente). Em casos de inflamação moderada ou intensa, a sensibilidade e especificidade dos critérios secundários de Schneider foram diminuídas, 33,3% e 50,0%, respectivamente (p = 0,0115). Conclusões Comparado a captura híbrida para o diagnóstico da infecção pelo HPV, a sensibilidade dos critérios secundários de Schneider foi maior que a dos critérios clássicos de Meisels. Inflamação moderada ou intensa reduziu a sensibilidade e especificidade dos critérios secundários de Schneider para o diagnóstico de infecção pelo HPV utilizando a captura híbrida como padrão-ouro.

Distribution of Human Papillomavirus 52 and 58 Genotypes, and Their Expression of p16 and p53 in Cervical Neoplasia

BACKGROUND: This study investigates the prevalence of human papillomavirus (HPV) 52 and 58 genotypes among women residing in Busan, and the expression of p16 and p53 proteins in cervical neoplasia with HPV 52 and 58 infections. METHODS: A total of three hundred fifteen cases were analyzed using the HPV DNA chip test for HPV genotypes, and of these, we retrospectively examined p16 and p53 expression in 62 cases of cervical tissues infected with HPV 52 and 58 using immunohistochemistry. RESULTS: HPV 52 and 58 genotypes were identified in 62 (54.9%) out of 113 high-risk, HPV-infected cases. Of the cases examined, there were 19 single HPV 52 infections (16.8%), 23 single HPV 58 infections (20.4%), 4 multiple HPV 52 infections (3.5%), and 16 multiple HPV-58 infections (14.2%). Immunoreactivity of p16 and p53 was observed in 41 (66.1%) and 23 (37.1%) of the 62 cases of cervical neoplasia infected with HPV 52 and 58 genotypes, respectively. CONCLUSIONS: This study demonstrates a high prevalence of HPV 52 and 58 genotypes, in addition to HPV 16, among high-risk strains of cervical neoplasia in Korea. These findings suggest that development of more vaccines would be beneficial for the prevention of the various HPV genotypes.

Adapting cervical dysplasia screening, treatment and prevention approaches to low resource settings.

Cervical cancer is a common disorder worldwide. Screening and treatment paradigms in highly developed countries have dramatically decreased disease prevalence and the implementation of preventive vaccination against high risk human papillomavirus (HPV) subtypes should decrease prevalence even further. Promising advances are also being made toward the development of a therapeutic vaccine for cervical neoplasia. Underresourced countries suffer from an inability to implement many of the approaches to prevention and diagnosis that have proved successful in countries with adequate resources. Several protocols are presently being developed that are low cost and require minimal training and infrastructure that may allow low-resource areas to begin to improve the early diagnosis of low and moderate grade cervical neoplasia. These protocols should support efforts at early treatment to prevent progression to cancer. Simultaneous expansion of prophylactic and possibly therapeutic vaccine availability is essential in the worldwide fight against this prevalent but largely preventable disease.

High-risk human papillomavirus infection among rural women of Jing'an County in Jiangxi Province:a cross-sectional study / 中国肿瘤临床

Objective:To investigate the prevalence of cervical infection with high-risk human papillomavirus (hr-HPV) among the rural women of Jing-an County in Jiangxi Province. Methods:A population-based cross-sectional study was conducted among rural women of ages 35 years to 59 years in Jing-an County between May 2012 and November 2012. A total of 4 673 women were enrolled. Hybrid capture2 (hc2) was detected in 2 491 women, whereas HybriMax was detected in 2 182 women to understand the different hr-HPV types. Results:The overall hr-HPV prevalence was 11.9%. Multiple-type infections accounted for 41.5%. The most commonly seen hr-HPV type was HPV52 (2.8%), followed by HPV58, HPV16, and HPV39. No significant difference was observed in the preva-lence of hr-HPV infection between women in the mountainous and the plain areas in Jing-an County. However, the age distribution of HPV infection significantly differed (P<0.001). Conclusion:Hr-HPV infection rate in Jing-an County was close to that of other areas in China. HPV52 and HPV58 appeared to be the most prevalent HPV types and should be employed as a basis for HPV prevention in this area.

Results of a control quality strategy in cervical cytology / Resultados de uma estratégia de controle de qualidade em colpocitologia

Objective: To determine the efficacy of a quality control strategy in cervical cytology in the detection of high-grade squamous intraepithelial lesions. Methods: Forty-two patients were selected who underwent a Pap smear and cervical uterine biopsy between April 2008 and December 2009, with evidence of a high-grade squamous intraepithelial lesion in one or both tests. The statistical parameters of the smear test were calculated before and after systematic meetings for review of the archived test results (6 years), in which the following was done: interobserver diagnostic consensus; cytohistological correlation, with the latter as gold standard; and evaluation of the therapeutic status of each patient. Results: Once these controls were applied, it was noted that sensitivity and positive likelihood ratio of the test for high-grade squamous intraepithelial lesion increased 9.5% (34.5 to 44%) and 0.45% (1.64 to 2.09%), respectively, while specificity remained at 79%. Reduction in interference of false-negative results associated with errors in the analytical phase of the cytological productive process gave an estimate of failures in collection of the specimens (pre-analytical phase). Conclusion: In addition to improving the performance of the cytological diagnosis of the high-grade squamous intraepithelial lesion, the proposed quality control strategy allows a reflection on the causes of incorrect or conflicting scrutiny.

Objetivo: Determinar a eficácia de uma estratégia de controle de qualidade em colpocitologia na detecção da lesão intraepitelial escamosa de alto grau. Métodos: Foram selecionadas 42 pacientes que realizaram Papanicolaou e biópsia cervicouterina entre abril de 2008 e dezembro de 2009, com evidência de lesão intraepitelial escamosa de alto grau em um ou em ambos os exames. Os parâmetros estatísticos do esfregaço foram calculados antes e após reuniões sistematizadas de revisão dos exames arquivados (6 anos), nas quais se procedeu a: consensualização diagnóstica interobservadores; correlação cito-histológica, sendo a última padrão-ouro; e avaliação do status terapêutico de cada paciente. Resultados: Aplicados tais controles, observou-se que a sensibilidade e a likelihood ratio positiva do teste para lesão intraepitelial escamosa de alto grau aumentaram 9,5% (34,5 para 44%) e 0,45% (1,64 para 2,09%), respectivamente, enquanto sua especificidade se manteve em 79%. A redução da interferência dos falso-negativos associados a erros na fase analítica do processo produtivo citológico traz estimativa das falhas de coleta do material (fase pré-analítica). Conclusão: Além de melhorar o desempenho do diagnóstico colpocitológico de lesão intraepitelial escamosa de alto grau, a estratégia de controle de qualidade proposta permite refletir sobre as causas de escrutínio incorreto ou discordante.

Acceso a la información de mujeres con VPH, displasia y cáncer cervical in situ / Access to information by women with HPV, cervical dysplasia and cancer in situ

OBJETIVO: Presentar un análisis relacional de cómo mujeres diagnosticadas con el virus del papiloma humano (VPH), displasia del cuello del útero o neoplasias del cuello uterino, reciben y/o acceden a la información y cómo la viven en sus relaciones cercanas. MATERIAL Y MÉTODOS: En 2008 se realizaron 34 entrevistas cualitativas a mujeres en dos clínicas de colposcopía de la Secretaría de Salud, en Hermosillo, Sonora. El análisis se basó en la teoría fundamentada. RESULTADOS: Existe una franca analogía entre cáncer cervicouterino (CaCu) y muerte, una amplia desinformación sobre VPH y displasias y una práctica persistente entre los médicos de no ofrecer información oportuna y clara a las pacientes. Existe una apreciación estigmatizante hacia la infección por VPH que afecta las relaciones cercanas de las mujeres. CONCLUSIÓN: A pesar de la necesidad de las pacientes de obtener información, no la exigen al médico, lo que contribuye a su desconfianza y angustia.

OBJECTIVE: To present a relational analysis of how women who are diagnosed with the human papilloma virus (HPV), cervical dysplasia or cervical neoplasia receive or seek information, and how they experience this process within their immediate relationships. MATERIALS AND METHODS: In 2008, 34 qualitative interviews were carried out with women at two Secretary of Health colposcopy clinics in Hermosillo, Sonora. Analysis was based on grounded theory. RESULTS: There is a patent analogy between cervical cancer and death, much disinformation about HPV and dysplasias, and a persistent lack of timely and clear information given to patients by doctors. There is a stigma attached to HPV infection which affects women's immediate relationships. CONCLUSION: Despite patients' need to obtain information, they do not demand it from their doctor, which contributes to their anguish and distrust.
