Genital Human Papillomavirus Infection in women from Florianópolis - Santa Catarina, Brazil / Infecção genital pelo Papilomavírus Humano em mulheres de Florianópolis - Santa Catarina, Brasil

Introduction: Human Papillomavirus (HPV) infection is the most common sexually transmitted infection in women. About 80% of sexually active women will have contact with this virus at some age in their lives. Most infections will be transient, but when the infection becomes persistent, associated with high oncogenic risk HPV, there may be progression to cancer, especially cervical cancer. The best way to prevent HPV infection is through the use of vaccines. Objective: To assess which are the most prevalent types of HPV in the city of Florianópolis, Brazil and if the majority of the diagnosed types are contained in the HPV vaccines currently available on the market and in the public health sector. Methods: More than 14,727 HPV tests were evaluated for the diagnosis of genital HPV infection in women from Florianópolis. The prevalence of infection was evaluated according to age of the women. HPV detection was performed using molecular biology tests, such as hybrid capture (for diagnosis of the HPV group, high or low oncogenic risk) and PCR (viral genotyping) techniques. Results: The diagnosis of HPV infection was made for women between one and 102 years of age. The highest positivity of the exams was observed in women aged 20­25 years (51% of the exams). The most prevalent age group was 31­35 years old (23.5%), and the lowest was for women aged 70 and above (0.6%). High oncogenic risk HPV was detected in 94.1% of positive samples and was the most frequent in all age groups. Mixed infection (high- and low-risk HPV) was more prevalent in the 66­70 age group (25.6%). The most frequent genotypes were non-16/18 high oncogenic risk HPV (77% of positive cases). HPV 16 was found in 17.1% of positive cases, and HPV 18 in 6.5%. Conclusion: The most prevalent types of HPV in Florianópolis in the last 6 years are non-16/18 high oncogenic risk HPV types, viral types not covered by the current HPV vaccine available in the public health sector in Brazil.

Introdução: A infecção pelo Papilomavírus Humano (HPV)é a infecção sexualmente transmissível mais frequente na mulher. Cerca de 80% das mulheres sexualmente ativas irão entrar em contato com este vírus em algum momento da sua vida. A maioria das infecções será transitória, mas quando a infecção se torna persistente, associada aos HPV de alto risco oncogênico, poderá haver a progressão para o câncer, principalmente o câncer de colo de útero. A melhor forma de prevenção da contaminação pelo HPV é através da utilização das vacinas. Objetivo: Avaliar quais são os tipos de HPV mais prevalentes na cidade de Florianópolis, Brasil, e se a maioria dos tipos diagnosticados estão contidos nas vacinas contra o HPV atualmente disponíveis no mercado e no setor público de saúde. Métodos: Foram avaliados 14.727 exames para diagnóstico da infecção genital pelo HPV em mulheres de Florianópolis, de acordo com a idade das mulheres. A detecção do HPV foi realizada através dos exames de biologia molecular pelas técnicas de captura híbrida (para diagnóstico do grupo de HPV, alto ou baixo risco oncogênico) e PCR (genotipagem viral). Resultados: Foram avaliados exames para diagnóstico da infecção de mulheres entre um e 102 anos de idade. A maior positividade dos exames foi observada em mulheres dos 20­25 anos (51% dos exames). A faixa etária de maior prevalência foi dos 31­35 anos (23,5%), e a menor, após os 70 anos (0,6%). O HPV de alto risco oncogênico foi detectado em 94,1% dos casos positivos e foi o mais frequente em todas as faixas etárias. A infecção mista (HPV de alto e baixo risco) foi mais prevalente na faixa etária dos 66­70 anos (25,6%). Os genótipos mais frequentes foram os HPV de alto risco oncogênico não 16/18 (77% dos casos positivos). O HPV 16 foi encontrado em 17,1% dos casos positivos, e o HPV 18 em 6,5%. Conclusão: Os tipos de HPV mais prevalentes em Florianópolis nos últimos 6 anos são os HPV de alto risco oncogênico não 16/18, tipos virais não cobertos pela atual vacina contra o HPV disponível no setor público de saúde do Brasil.Palavras-chave: HPV.

Variabilidade espacial intraurbana da mortalidade por câncer de mama e do colo do útero no município de São Paulo: análise dos fatores associados / Intra-urban spatial variability of breast and cervical cancer mortality in the city of São Paulo: analysis of associated factors

RESUMO Objetivo: Identificar a variabilidade espacial da mortalidade por câncer de mama e colo do útero e avaliar fatores associados à mortalidade por esses cânceres no município de São Paulo. Métodos: Entre 2009 e 2016 foram registrados, no Sistema de Informações sobre Mortalidade, 10.124 óbitos por câncer de mama e 2.116 óbitos por câncer do colo do útero em mulheres com 20 anos e mais. Os registros foram geocodificados por endereço de residência e agregados segundo território adstrito. Foram realizadas modelagens de regressão espacial utilizando-se a abordagem bayesiana com estrutura de Besag-York-Mollié para verificar a associação dos óbitos com indicadores selecionados. Resultados: As taxas de mortalidade por esses cânceres apresentaram padrões espaciais inversos. As variáveis associadas à mortalidade por câncer de mama foram: tempo de deslocamento para o trabalho entre uma e duas horas (risco relativo — RR 0,97; intervalo de credibilidade — IC95% 0,93-1,00); mulheres responsáveis pelo domicílio (RR 0,97; IC95% 0,94-0,99) e óbitos por câncer de mama ocorridos em estabelecimentos privados (RR 1,04; IC95% 1,00-1,07). À mortalidade por câncer do colo do útero, estiveram associados: tempo de deslocamento para o trabalho entre meia e uma hora (RR 0,92; IC95% 0,87-0,98); rendimento domiciliar até três salários-mínimos (RR 1,27; IC95% 1,18-1,37); e razão de menores de um ano em relação à população feminina de 15 a 49 anos (RR 1,09; IC95% 1,01-1,18). Conclusão: Foram calculados os RR preditos para a mortalidade por esses cânceres, que estiveram associados às condições socioeconômicas das áreas de abrangência.

ABSTRACT Objective: To identify spatial variability of mortality from breast and cervical cancer and to assess factors associated in the city of São Paulo. Methods: Between 2009 and 2016, 10,124 deaths from breast cancer and 2,116 deaths from cervical cancer were recorded in the Mortality Information System among women aged 20 years and over. The records were geocoded by address of residence and grouped according to Primary Health Care coverage areas. A spatial regression modeling was put together using the Bayesian approach with a Besag-York-Mollié structure to verify the association of deaths with selected indicators. Results: Mortality rates from these types of cancer showed inverse spatial patterns. These variables were associated with breast cancer mortality: travel time between one and two hours to work (RR - relative risk: 0.97; 95%CI - credible interval: 0.93-1.00); women being the head of the household (RR 0.97; 95%CI 0.94-0.99) and deaths from breast cancer in private health institutions (RR 1.04; 95%CI 1.00-1.07). The following variables were associated with mortality from cervical cancer: travel time to work between half an hour and one hour (RR 0.92; 95%CI 0.87-0.98); per capita household income of up to 3 minimum wages (RR 1.27; 95%CI 1.18-1.37) and ratio of children under one year of age related to the female population aged 15 to 49 years (RR 1.09; 95%CI 1.01-1.18). Conclusion: The predicted RR for mortality from these cancers were calculated and associated with the socioeconomic conditions of the areas covered.

Fatores associados ao início do tratamento especializado em tempo inoportuno após diagnóstico do câncer do colo do útero no Estado da Bahia, Brasil / Factores asociados con el inicio del tratamiento especializado en tiempo inadecuado tras un diagnóstico de cáncer de cuello de útero en el estado de Bahía, Brasil / Factors associated with delay in specialized treatment after diagnosis of cervical cancer in Bahia State, Brazil

Este estudo teve o objetivo de analisar os fatores associados ao tratamento especializado em tempo inoportuno após diagnóstico do câncer do colo do útero no Estado da Bahia, Brasil. Trata-se de um estudo de base hospitalar, de corte transversal, realizado com mulheres tratadas em unidades credenciadas ao sistema de Registro Hospitalar de Câncer (RHC) do Estado da Bahia, no período de 2008 a 2017. Foi realizada análise descritiva e regressão logística, construída na modelagem stepwise backward, para estimar as razões de prevalência (RP) bruta e ajustada, sendo consideradas estatisticamente significantes aquelas com o valor de p ≤ 0,05 pelo teste qui-quadrado de Pearson. Foram analisados 9.184 casos, destes, 65% tiveram tratamento em tempo inoportuno (tempo transcorrido entre o diagnóstico e o primeiro tratamento > 60 dias). A prevalência de tratamento em tempo inoportuno apresentou valores mais elevados entre mulheres com 65 anos ou mais (RP = 1,30; IC95%: 1,21-1,39), nenhuma escolaridade (RP = 1,24; IC95%: 1,15-1,33) e estadiamento avançado (RP = 1,17; IC95%: 1,13-1,21). Na maioria dos casos analisados, houve tratamento em tempo inoportuno, com maior prevalência entre as mulheres com mais idade, menor escolaridade e estadiamento clínico do tumor avançado, evidenciando a necessidade de ampliação do acesso aos serviços de tratamento oncológico no Estado da Bahia, em especial para estes grupos que apresentaram pior situação.

El objetivo de este estudio fue analizar los factores asociados al tratamiento especializado en un tiempo inadecuado, tras el diagnóstico del cáncer de cuello de útero en el estado da Bahía, Brasil. Se trata de un estudio con base hospitalaria, de corte transversal, realizado con mujeres tratadas en unidades acreditadas en el sistema de Registro Hospitalario de Cáncer (RHC) del estado de Bahía, en el período de 2008 a 2017. Se realizó un análisis descriptivo y regresión logística, construida en el modelado stepwise backward, para estimar las razones de prevalencia (RP) bruta y ajustada, siendo consideradas estadísticamente significativas aquellas con el valor de p ≤ 0,05, mediante el test chi-cuadrado de Pearson. Todos los análisis fueron procesados en el programa Stata versión 16.0. Se analizaron 9.184 casos, de estos, un 65% tuvieron tratamiento en un tiempo inadecuado (tiempo transcurrido entre el diagnóstico y el primer tratamiento > 60 días). La prevalencia de tratamiento en tiempo inoportuno presentó valores más elevados entre mujeres con 65 años o más (RP = 1,30; IC95%: 1,21-1,39), ninguna escolaridad (RP = 1,24; IC95%: 1,15-1,33) y estadio avanzado (RP = 1,17; IC95%: 1,13-1,21). En la mayoría de los casos analizados, hubo tratamiento en un tiempo inadecuado, con mayor prevalencia entre las mujeres con más edad, menor escolaridad y estadio clínico del tumor avanzado, evidenciando la necesidad de una ampliación del acceso a los servicios de tratamiento oncológico en el estado de Bahía, en especial para estos grupos que presentaron peor situación.

This study aimed to analyze factors associated with delay in specialized treatment after diagnosis of cervical cancer in the State of Bahia, Brazil. This was a cross-sectional hospital-based study of women treated in accredited units in the Hospital-Based Cancer Registry (HBCR) system in the State of Bahia from 2008 to 2017. A descriptive analysis and logistic regression were performed with backward stepwise modeling to estimate crude and adjusted prevalence ratios (PR), defining statistical significance as p ≤ 0.05 in Pearson's chi-square test. We analyzed 9,184 cases, and 65% had delayed treatment (time between diagnosis and first treatment > 60 days). Delayed treatment was more prevalent among women 65 years or older (PR = 1.30; 95%CI: 1.21-1.39), with no schooling (PR = 1.24; 95%CI: 1.15-1.33), and in advanced stages (PR = 1.17; 95%CI: 1.13-1.21). Most of the cases analyzed had delayed treatment, more prevalent among older women, with less schooling, and advanced tumor stages, highlighting the need to expand access to cancer treatment services in Bahia state, especially for these groups in worse conditions.

Impacts of treatment modes on the prognosis of Ⅰ B1-Ⅱ A patients with intermediate-risk recurrence factors / 中华放射医学与防护杂志

Objective:To analyze the prognostic factors of patients with Ⅰ B1-Ⅱ A cervical cancers after surgery and to assess the effects and adverse reactions of intensity-modulated radiotherapy(IMRT)combined with concurrent chemotherapy(CCRT). Methods:A retrospective analysis was performed based on the clinical and follow-up data of 362 patients with Ⅰ B1-Ⅱ A cervical cancers who were treated in Changzhou Second People′s Hospital from January 2009 to December 2019. Meanwhile, these patients suffered large primary tumors(LPT; tumors size: ≥4 cm), lymphatic vascular space invasion (LVSI), and deep stromal invasion(DSI; stromal infiltration depth: ≥1/2) after surgery and showed at least one intermediate-risk factor. Among these cases, 161 cases were treated with CCRT, 131 cases under-went single radiotherapy (RT), and 70 cases received unadjuvanted radiotherapy. The Kaplan-Meier method and the logrank test were adopted for univariate survival analysis, the binary logistic regression was used to analyze the recurrence risk, and Cox regression model was used for multivariate survival analysis. Results:The 3 and 5-year overall survival (OS) rates were 94.20% and 88.39%, respectively. The retrospective analysis showed that the risk factors of recurrence included tumor size ≥ 4 cm and poorly differentiated cancers( OR=3.287, 2.870, 95% CI: 1.366-7.905, 1.105-7.457, P<0.05). Compared with the treatment without adjuvant radiotherapy and RT, CCRT reduced the recurrence rate of tumors with tumor size of ≥ 4 cm, adenocarcinomas or adenosquamous carcinomas (pathological types), and poorly differentiated carcinomas( χ2=6.725-7.518, P<0.05). A multivariate analysis showed that the CCRT improved the recurrence-free survival ( HR=0.290, 95% CI: 0.128-0.659, P=0.003) and OS ( HR=0.370, 95% CI: 0.156-0.895, P=0.024). A subgroup analysis indicated that CCRT prolonged the OS of patients with tumor size ≥ 4 cm or poorly differentiated cancers compared to the patients receiving no radiotherapy or those treated with RT (χ 2=7.614, 5.964, P<0.05). Compared with the cases receiving single radiotherapy, those receiving CCRT did not suffer an increase in the incidence of hematology, radiation enteritis, and cystitis above grade 3 according to observation ( P>0.05). Conclusions:Among the intermediate-risk factors leading to the recurrence of postoperative cervical cancers, the factors of large primary tumors or poorly differentiated cancers affect the prognosis of patients.Compared with RT and the treatment without adjuvant radiotherapy, IMRT combined with concurrent chemotherapy can prolong the recurrence-free survival and overall survival of patients with large tumors or poorly differentiated cancers and adverse reactions induced are tolerable.

Cáncer cérvico uterino: prevención y tratamiento / Cervical uterine cancer: prevention and treatment

RESUMEN El cáncer cérvico uterino es una alteración celular que se origina en el epitelio del cuello del útero debido a la persistencia de serotipos oncogénicos del virus del papiloma humano y que se manifiesta inicialmente a través de lesiones precancerosas de lenta y progresiva evolución. Sigue siendo la primera causa de morbimortalidad en mujeres de países en vías de desarrollo. Los datos estadísticos mundiales indican que al año se producen unos 466.000 nuevos casos, 80 % de ellos en países en vías de desarrollo, de los cuales mueren 274.000 mujeres, a pesar de ser una enfermedad prevenible. El objetivo de esta revisión es compilar información sobre su prevención y tratamiento, para poder ser utilizada con fines docentes.

ABSTRACT Cervical uterine cancer is a cellular alteration which starts in the cervix epithelium due to the persistence of human papillomavirus oncogenic serotypes and that initially manifests itself through precancerous lesions of slow and progressive evolution. It still is the leading cause of morbidity and mortality in women in developing countries. World statistical data indicates that some 466,000 new cases occur each year, 80% of them in developing countries, of which 274,000 women die, despite being a preventable disease. The objective of this review is to compile information on its prevention and treatment, in order to be used for educational purposes.

Conocimientos, actitudes y prácticas sobre la prueba de citología cervical en una población rural peruana / Knowledge, attitudes and practices on cervical cytology in a Peruvian rural population

Introducción: La citología cervical constituye la principal herramienta para la detección y tratamiento del cáncer de cérvix. Algunos estudios llevados a cabo en población urbana han relacionado la realización y adherencia con los conocimientos, las actitudes y las prácticas favorables de las mujeres con respecto a esta prueba. Objetivo: evaluar los conocimientos, actitudes y prácticas con respecto a la citología cervical en mujeres pertenecientes a un grupo poblacional del ámbito rural. Material y Métodos: estudio de corte transversal-analítico en una población de aproximadamente 3148 mujeres en edad fértil, de ellas se obtuvo una muestra representativa. Se utilizó una encuesta anónima, validada, dirigida, y aplicada por personal de salud capacitado que labora en centros de salud del primer nivel de atención de los distritos de la provincia de Bolívar, La Libertad. Resultados: El 80 por ciento de las mujeres encuestadas tuvo un nivel de conocimiento alto e intermedio, el 70 por ciento una actitud favorable, mientras que el 44 por ciento reportó prácticas correctas en relación con la prueba de citología cervical. El nivel de conocimiento alto e intermedio estuvo asociado a la edad mayor de 30 años (p:0.02), estado civil casada (p:0.05), el mayor grado de instrucción (p:0.00) y el uso de métodos anticonceptivos (p:0.01); no se encontró relación con la edad de inicio de relaciones sexuales (p:0.98). Conclusiones: Existe un alto nivel de conocimientos, actitudes y prácticas correctas hacia la citología cervical en la población rural de la provincia de Bolívar, pero una baja adherencia hacia la misma(AU)

Introduction: Cervical cytology is the main tool for the detection and treatment of cervical cancer. Some studies carried out in the urban population have associated the realization and adherence with knowledge, attitudes and favorable practices of women with respect to this test. Objective: The aim of this study was to determine the level of knowledge, attitudes and practices towards cervical cytology in women of childbearing age in a rural Peruvian province. Material and Methods: A cross-sectional analytical study was conducted in a population of approximately 3148 women of childbearing age, a representative sample was obtained. An anonymous, validated, directed survey was used; it was applied by trained health personnel working in health centers of the primary care level in the districts of the province of Bolívar, La Libertad. Results: A total of 400 surveys were carried out. The results showed that 80 percent of the women surveyed had high and intermediate levels of knowledge, 70 percent had a favorable attitude, while 44 percent reported correct practices related to the cervical cytology test. The high and intermediate levels of knowledge were associated with age over 30 years (p: 0.02), married marital status (p: 0.05), the highest level of instruction (p: 0.00) and the use of contraceptive methods (p: 0.01); no relationship was found with the age of onset of sexual intercourse (p: 0.98). Conclusions: There is a high level of knowledge, attitudes and correct practices towards cervical cytology in the rural population of the province of Bolívar, but a low adherence to it(AU)

Analysis of cervical cancer mortality rate trends in Natal-RN, Brazil, between 2000 and 2012 / Análisis de las tendencias de la tasa de mortalidad por cáncer de cuello uterino en Natal-RN, Brasil, entre 2000 y 2012

ABSTRACT Objective To describe cervical cancer mortality rates and their corresponding trends, and to analyze the spatial correlations of this type of cancer in Natal-RN, Brazil, between 2000 and 2012. Materials and Methods The simple linear regression model, the empirical Bayes method and the Global Moran's index were used for the statistical analysis. Results The mortality coefficient of cervical cancer in Natal, standardized by age range, was 5.5 per 100 000 women. All historical series for the coefficients studied were classified as stable. The Global Moran's index obtained was 0.048, with a p-value for the spatial test correlation between neighborhoods of 0.300. The average family income by neighborhood showed no significant correlation to cervical cancer mortality rates. Conclusion This study found a temporal stabilization and spatial independence trend of cervical cancer mortality rates in women from Natal, as well as the absence of correlation between these rates and the average family income of the of the participating women distributed by neighborhoods. In view of this, changes in the public policies should be made aimed at preventing the disease; adopting these measures could positively impact the screening program, improving the coverage of Pap smears and immunization campaigns against HPV, in order to reverse this trend and achieve a reduction of mortality rates.(AU)

RESUMEN Objetivo Describir las tasas de mortalidad por cáncer de cuello uterino y sus tendencias, así como analizar las correlaciones espaciales de este tipo de cáncer en Natal-RN, Brasil, entre 2000 y 2012. Materiales y Métodos Para el análisis estadístico se utilizaron el modelo de regresión lineal simple, la estimación empírica de Bayes y el índice Moran Global. Resultados La tasa de mortalidad por cáncer de cuello uterino en Natal, estandarizado por rango de edad, fue 5.5 por cada 100 000 mujeres. Todas las series históricas para los coeficientes estudiados se clasificaron como estables. El índice Moran Global obtenido fue 0.048, con un valor p de 0.300 para la correlación de prueba espacial entre vecindarios. El ingreso familiar promedio por vecindario no mostró correlación significativa con las tasas de mortalidad por cáncer de cuello uterino. Conclusión En este estudio se observó una tendencia temporal de estabilización e independencia espacial de la tasa de mortalidad por cáncer cervical en mujeres de Natal, así como la ausencia de correlación entre estas tasas y el ingreso familiar promedio de las mujeres participantes, distribuidas por vecindarios de la ciudad. En vista de esto, se sugiere que se adopten cambios en las políticas públicas dirigidas a la prevención de la enfermedad que apunten a medidas que puedan tener un impacto positivo en el programa de monitoreo, mejorando la cobertura de la prueba de Papanicolaou, así como de las campañas de vacunación contra el VPH, con el objetivo de revertir esta tendencia y lograr una reducción en las tasas de mortalidad de la enfermedad.(AU)

A randomized controlled trial comparing concurrent chemoradiation versus concurrent chemoradiation followed by adjuvant chemotherapy in locally advanced cervical cancer patients: ACTLACC trial / 부인종양

OBJECTIVE: To compare response rate and survivals of locally advanced stage cervical cancer patients who had standard concurrent chemoradiation therapy (CCRT) alone to those who had adjuvant chemotherapy (ACT) after CCRT. METHODS: Patients aged 18–70 years who had International Federation of Gynecology and Obstetrics stage IIB–IVA without para-aortic lymph node enlargement, Eastern Cooperative Oncology Group scores 0–2, and non-aggressive histopathology were randomized to have CCRT with weekly cisplatin followed by observation (arm A) or by ACT with paclitaxel plus carboplatin every 4 weeks for 3 cycles (arm B). RESULTS: Data analysis of 259 patients showed no significant difference in complete responses at 4 months after treatment between arm A (n=129) and arm B (n=130): 94.1% vs. 87.0% (p=0.154) respectively. With the median follow-up of 27.4 months, 15.5% of patients in arm A and 10.8% in arm B experienced recurrences (p=0.123). There were no significant differences of overall or loco-regional failure. However, systemic recurrences were significantly lower in arm B than arm A: 5.4% vs. 10.1% (p=0.029). The 3-year progression-free survival (PFS) and 3-year overall survival (OS) of the patients in both arms were not significantly different. The hazard ratio of PFS and OS of arm B compared to arm A were 1.26 (95% CI=0.82–1.96; p=0.293) and 1.42 (95% CI=0.81–2.49; p=0.221) respectively. CONCLUSIONS: ACT with paclitaxel plus carboplatin after CCRT did not improve response rate and survival compared to CCRT alone. Only significant decrease of systemic recurrences with ACT was observed, but not overall or loco-regional failure.

Detección de cáncer cérvico- uterino: ¿prueba citológica a partir de los 25 años? / Detection of Cervical Uterine Cancer: cytology after 25 years old?

En Cuba, al igual que en el resto de los países occidentales, el cáncer cérvico-uterino se encuentra en segundo lugar de morbilidad oncológica en mujeres de 20 a 30 años. También hay estudios que revelan información deficiente por parte de las adolescentes en cuanto a las infecciones de transmisión sexual y sus consecuencias, entre las que se encuentra el enfermar de cáncer. Este artículo tiene como objetivo reflexionar acerca de la incidencia de esta enfermedad en edades tempranas, sin embargo el programa para su detección contempla la realización de pruebas citológicas a partir de los 25 años. Se impone entonces pensar en las medidas a tomar para que este flagelo no afecte a mujeres en edades tan tempranas.

In Cuba, as in other western countries, Cervical Uterine Cancer is in the second place of oncological morbidity in women from 20 to 30 years old. There also studies which show deficient information about adolescents regarding sexually transmitted diseases and their consequences, among them developing cancer. This article is aimed at reflecting about the incidence of this disease at early ages; however the program for its detection includes performing cytology starting at 25 year old. It necessary then, to think the measures to be taken so that this scourge does not affect young women.

IA1 microinvasive cervical adenocarcinoma in a young woman: conservative procedure and reproductive outcome / Adenocarcinoma microinvasor IA1 do colo do útero em mulher jovem: conduta conservadora e resultado reprodutivo

Introduction: The expansion of cytological screening programs for cervical cancer leads to an increase in the proportion of both adenocarcinomas and diagnoses in young women with reproductive intention. Conservative treatment is not fully established. Objective: to report the conservative management and follow-up difficulties of a real case of microinvasive cervical adenocarcinoma in a young woman. Case report: This is a case report of a 23-yearold patient with stage IA1 microinvasive cervical adenocarcinoma related to HPV18. The patient was vaccinated against HPV 16/18 at 16 years of age and conservatively treated. She became pregnant during follow-up with a favorable outcome. Conclusion: We discuss the difficulties and uncertainties regarding follow-up and opportunity for hysterectomy, emphasizing the need for a multidisciplinary approach to make a balanced decision between conservative treatment and oncological safety, as well as mitigate follow-up difficulties in real life.

Introdução: A ampliação dos programas de rastreamento citológico de câncer do colo uterino resulta em aumento na proporção de adenocarcinomas e de diagnósticos em jovens ainda com desejo reprodutivo. O tratamento conservador não está totalmente estabelecido. Objetivo: descrever a condução conservadora e as dificuldades de seguimento em caso real de adenocarcinoma microinvasor do colo em uma jovem. Relato de caso: É relatado o caso de uma paciente de 23 anos com adenocarcinoma microinvasor IA1 do colo uterino relacionado ao HPV 18, mesmo vacinada contra HPV 16/18 aos 16 anos. Foi tratada conservadoramente, com gestação e desfecho favorável. Conclusão: São discutidas as dificuldades e incertezas em relação ao seguimento e à oportunidade para histerectomia, ressaltando a necessidade de abordagem multidisciplinar para decisões equilibradas entre tratamento conservador, segurança oncológica e, ainda, amenizar as dificuldades de seguimento na vida real.

Management of atypical squamous cell cases: A prospective study of women seen at a private health service in northeastern Brazil / Conduta em casos de células escamosas atípicas: um estudo prospectivo de mulheres atendidas pelo serviço de saúde privado no nordeste do Brasil

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.

Effect of tibolone on the survival of early stage cervical adenocarcinoma patients

OBJECTIVE: Gynecologic oncologists are uncertain about the safety of tibolone application in cervical adenocarcinoma (AC) patients. This study examined the possible adverse effects of tibolone on the survival of cervical AC patients. METHODS: Medical records of 70 cervical AC patients with International Federation of Gynecology and Obstetrics stages IA to IB were reviewed. A bilateral salpingo-oophorectomy was performed in all patients, and survival outcomes between tibolone users (n=38) and non-users (n=32) were compared. RESULTS: A comparison of the tibolone users with non-users revealed similar clinicopathological variables. Progression-free survival (P=0.34) and overall survival (P=0.22) were similar in the users and non-users. The risks of progression (hazard ratio [HR], 1.71; 95% confidence interval [CI], 0.46–6.37; P=0.43) and death (HR, 1.59; 95% CI, 0.06–45.66; P=0.79) were also similar in both groups. CONCLUSION: Tibolone has no adverse effect on the survival of cervical AC patients and can be administered safely to this population. These findings may be helpful in improving the quality of life of cervical AC patients.

Evaluation of clinical efficacy and safety of single-channel intracavitary applicator for uterine cervical cancer: early results of a prospective randomized phase Ⅱ clinical trial / 中华放射肿瘤学杂志

Objective@#To evaluate whether the self-designed single-channel intracavitary applicator yields equivalent clinical efficacy and safety to the standard Fletcher-type three-channel applicator in the high-dose-rate (HDR) brachytherapy for uterine cervical cancer.@*Methods@#From December 2011 to April 2017, patients initially diagnosed with cervical cancer were randomly assigned into the external beam radiotherapy (EBRT)+ single-channel intracavitary applicator group (the patent single-channel group) and EBRT+ the Fletcher applicator group. Whole pelvis irradiation was delivered with 6-MV photons via a four-field box variant or anterior and posterior parallel fields. Five to six fractions of intracavitary brachytherapy were performed at a dose of 7 Gy at point A once a week after 30 Gy (BED at point A: 80-90 Gy). Chemotherapy was given with intravenous injection of cisplatin at a dose of 40 mg/m2 once weekly during EBRT.Clinical efficacy and safety were evaluated after the treatment.@*Results@#In total, 150 eligible cases were assigned into the Fletcher applicator group and 149 cases into the patent single-channel group. The short-term clinical efficacy and acute toxicity did not significantly differ between two groups. The response rate was 94.0% in the Fletcher group, and 94.7% in the patent single-channel group. In the Fletcher applicator group, 76(50.7%) patients developed ≥ grade 3 hematologic toxicity and 61(40.9%) in the patent group (P=0.195).@*Conclusions@#The self-designed patent single-channel intracavitary applicator yields equivalent clinical efficacy and safety (acute toxicity) to the standard Fletcher-type three-channel applicator in the HDR brachytherapy for uterine cervical cancer.@*Clincal Trial Registration@#Chinese Clinical Trial Registry (ChiCTR-TRC-12002321).

Application of ultrasound for simulated positioning of brachytherapy in cervical cancer: An alternative to traditional MRI/CT? / 中华放射肿瘤学杂志

The role of three-dimensional brachytherapy (3D-BT) in the radical treatment of cervical cancer has been widely recognized. Obtaining the image information through simulated positioning is a key step of 3D-BT.Currently, MRI/CT positioning has been commonly applied in clinical practice, which has respective limitations when applied in radiosurgery. Consequently, it is of necessity to explore an accurate, highly efficient and convenient positioning approach. Besides MRI and CT, ultrasound is a novel positioning method in clinical settings. Through literature review, the application of ultrasound in 3D-BT was summarized, aiming to provide reliable reference for clinicians.

Calidad de la toma exo-endocervical en la prevención del cáncer de cuello uterino / Quality of the exo-endocervical sampling in the prevention of uterine cervix cancer

La citología cérvico-vaginal, test de Papanicolaou (PAP), es la técnica diagnóstica de cribado más efectiva para la detección de lesiones precancerosas y la prevención del cáncer de cuello uterino. La sensibilidad de la prueba varía en las diferentes estadísticas entre el 50% y el 98%; la causa de esta amplitud depende de la toma de muestra. Para que la toma se considere satisfactoria es necesario que se realice de la zona escamocolumnar, zona de transformación, y según el sistema Bethesda en el extendido se deben observar células metaplásicas y/o endocervicales. El PAP convencional incluye la toma exo-endocervical con espátula de Ayre; sin embargo, solo el 50% aproximadamente de las muestras son representativas de la zona de transformación. Para ejemplificar esta situación se presenta el caso de una mujer de 40 años que, a pesar de tener citologías negativas durante cinco años, ninguna con células endocervicales o metaplásicas, una toma adecuada mostró un carcinoma in situ (HSIL: lesión intraepitelial escamosa de alto grado). Recalcamos la importancia de la correcta toma exo-endocervical para poder detectar todas las lesiones premalignas y prevenir este tipo de cáncer que aún tiene alta tasa de mortalidad en todo el mundo.

Cervical and vaginal cytology, Papanicolaou test (PAP), is the most effective test for screening of preneoplastic lesions, and cervical cancer prevention. Its sensitivity goes from 50 to 98%, according to different statistics, and this variation is related to the sampling procedure. A satisfactory smear should be taken from the transformation zone, the junction between endocervix and exocervix. According to Bethesda, metaplastic and/or endocervical cells should be observed under the microscope. The traditional PAP smear includes an exo-endocervical sampling using the Ayre spatula; however, only near 50% of the smears are representative of the transformation zone. In this case report, we present the case of a 40-year-old woman who had negative cytology in five consecutive annual PAP smears, none of which showed metaplastic or endocervical cells. A new sample evidenced a carcinoma in situ (HSIL: high-grade squamous intraepithelial lesion). We emphasize the importance of performing a correct exo-endocervical sampling to allow prompt detection of all premalignant lesions and to prevent cervical cancer, which still persists with high mortality worldwide.

"Uma doença da mulher": experiência e significado do câncer cervical para mulheres que realizaram o Papanicolau / "A woman's illness": experience and meaning of cervical cancer of woman who underwent Pap test / "Una enfermedad de la mujer": experiencia y significado de cáncer cervical para las mujeres que se sometieron el Papanicolaou

Este artigo busca compreender a experiência e os significados do câncer cervical por mulheres que realizam o Papanicolau. Realizou-se pesquisa qualitativa, com entrevistas semiestruturadas, com mulheres, moradoras do Jardim Keralux, localizado na Zona Leste da Cidade de São Paulo, Brasil. O câncer cervical é considerado uma "doença invencível" quando está em estágio avançado, cujas "causas" remetem tanto à precariedade da atenção à saúde quanto às crenças religiosas e às concepções humorais do corpo. Trata-se de uma doença marcada pelas relações de gênero, que definem, assimetricamente, as relações entre o homem e a mulher no interior da família. O câncer cervical é concebido como uma doença do gênero feminino, de maneira que cabe à mulher cuidar de sua saúde por meio do Papanicolau.(AU)

This paper seeks to understand the experience and meanings of cervical cancer for women who underwent Pap Test. We conducted a qualitative research using semi-structured interviews with women who lives at Jardim Keralux, located at the eastern zone in São Paulo city, Brazil. Cervical cancer is considered an "invincible disease" when it is in an advanced stage. Its "causes" refer both to precariousness of the healthcare system, some religious beliefs and somebody humoral conceptions. It is a disease marked by gender relations, which asymmetrically defines the relationship between men and women with their family. Cervical cancer is conceived as a female disease, thus is a women's responsibility to take care of their health through the Pap Test.(AU)

En este artículo se trata de comprender la experiencia y los significados de cáncer cervical para las mujeres que se sometieron a la prueba de Papanicolaou. Se realizó una investigación cualitativa mediante entrevistas semiestructuradas con mujeres que viven en el Jardim Keralux, situados en la zona oriental de la ciudad de Sao Paulo, Brasil. El cáncer cervical se considera una "enfermedad invencible" cuando se encuentra en una fase avanzada. Sus "causas" se refieren a la precariedad del sistema de salud y las creencias religiosas y las concepciones humorales del cuerpo. Es una enfermedad que se caracteriza por las relaciones de género, que define la relación asimétrica entre hombres y mujeres en la familia. El cáncer cervical se concibe como una enfermedad femenina, por tanto, es responsabilidad de las mujeres a cuidar de su salud a través de Papanicolaou.(AU)

O câncer de colo do útero no Brasil: uma retrospectiva sobre as políticas públicas voltadas à saúde da mulher / Cervical cancer in Brazil: a retrospective on public policies for women's health

O câncer de colo do útero é a terceira neoplasia mais incidente entre as brasileiras, com taxa de mortalidade acima de 5/100 mil mulheres, apesar de possuir bom prognóstico quando diagnosticado em fases precoces. No Brasil, políticas públicas voltadas para o câncer de colo do útero vêm sendo desenvolvidas desde a década de 1970 e incluíram diversos programas de rastreamento, que conseguiram aumentar o acesso ao teste de Papanicolau, com patamar de cobertura estável nos últimos anos, em torno dos 83%. Em 2014, a vacina anti-HPV foi incluída no Calendário Nacional de Vacinação. O mais recente Plano de Ações Estratégicas possui metas de aumento da cobertura de exame citopatológico e tratamento de todas as mulheres com lesões precursoras. Outras duas iniciativas foram criadas: o Programa de Qualificação de Ginecologistas para Assistência Secundária às Mulheres com Alterações Citológicas Relacionadas às Lesões Intraepiteliais e ao Câncer de Colo do Útero e a formalização da Rede Colaborativa para a Prevenção do Câncer de Colo do útero. Mesmo com o constante avanço dessas medidas, mais de 70% das brasileiras são diagnosticadas em fases avançadas da doença, o que impacta negativamente no prognóstico. A análise dos protocolos de tratamento voltados para a saúde coletiva mostra defasagem em relação ao cenário internacional e nacional preconizado por sociedades médicas, especialmente no tratamento de fases tardias da doença. Apesar dos avanços na difusão de medidas preventivas e alcance de ampla cobertura do rastreamento, o câncer de colo do útero continua a ser um problema de saúde importante no país.

Cervical cancer is the third most frequent neoplasm among Brazilian women, with a mortality rate of more than 5/100 thousand women, despite having a good prognosis when diagnosed in the early stages. In Brazil, public policies for cervical cancer have been developed since the 1970s and have included several screening programs that have been able to increase access to the Papanicolaou test, with a stable coverage level in recent years, around 83%. In 2014, the anti-HPV vaccine was included in the National Vaccination Calendar. The most recent Strategic Action Plan has targets to increase coverage of cytopathological examination and treatment of all women with precursor lesions. Two other initiatives were created: the Qualification Program of Gynecologists for Secondary Care for Women with Cytologic Alterations Related to Intraepithelial Lesions and Cervical Cancer, and the formalization of the Collaborative Network for the Prevention of Cervical Cancer. Even with constant progress of these measures, more than 70% of Brazilian women are diagnosed in advanced stages of the disease, which negatively impacts the prognosis. The analysis of treatment protocols aimed at public health shows lag in relation to international and national scenario recommended by medical societies, especially in the treatment of late stage disease. Despite the advances in the dissemination of preventive measures and the scope of extensive screening coverage, cervical cancer remains a major health problem in the country.

Prevenção do câncer cervicouterino: uma ação realizada pelos enfermeiros da estratégia saúde da família? / Cervical cancer prevention: an action taken by nurses of the family health strategy?

Objetivo: Analisar as intervenções de prevenção e promoção da saúde relacionadas a detecção precoce do câncer cervicouterino desenvolvidas pelos enfermeiros das equipes da Estratégia Saúde da Família (ESF) do município de Assú/RN. Métodos: Realizou-se um estudo descritivo, com abordagem qualitativa, junto a 11 enfermeiros, no mês de julho de 2016, representando 61% dos enfermeiros lotados na ESF selecionada. O material coletado, através de entrevistas abertas, foi submetido à análise de conteúdo temática proposta por Bardin. As falas produziram duas categorias de análise: práticas preventivas do câncer cervicouterino e práticas de educação/promoção da saúde. Resultados: Os resultados apontam que as ações relacionadas a prevenção e controle do câncer cervicouterino realizadas pelos enfermeiros, ainda são incipientes. O atendimento, às mulheres, ocorre por meio de demanda espontânea, não havendo o necessário rastreamento, visando evitar o câncer de colo uterino na faixa etária preconizada pelo Ministério da Saúde. As ações educativas são esporádicas e implementadas, principalmente, por ocasião das Campanhas promovidas pelo Ministério da Saúde, como por exemplo, o outubro Rosa. Conclusões: Fazse necessário que as ações dos enfermeiros da ESF, no que concerne a detecção precoce e rastreamento do câncer do colo do útero sejam redirecionadas e, ademais, que a educação em saúde possa ser implantada de forma a promover o empoderamento das mulheres com vistas ao autocuidado e a promoção da saúde (AU).

Objective: The prevention and health promotion interventions related to the early detection of cervical cancer developed by the nurses of the Family Health Strategy (ESF) teams in the city of Assú / RN were analyzed. Methods: A descriptive study with a qualitative approach was carried out, together with 11 nurses, in July 2016, representing 61% of nurses filled with ESF. The collected material, through open interviews, was submitted to the thematic content analysis proposed by Bardin. The statements produced two categories of analysis: cervical cancer preventive practices and health education / promotion practices. Results: The results indicate that the actions related to the prevention and control of cervical cancer by nurses are still incipient. The care given to women occurs through spontaneous demand, and there is no necessary screening, in order to avoid cervical cancer in the age range advocated by the Ministry of Health. Educational actions are sporadic and implemented mainly during the campaigns promoted by the Ministry of Health, for example, the October Rose. Conclusions: It is necessary that the actions of nurses of the ESF, in what concerns the early detection and screening of cervical cancer, should be redirected and, in addition, that health education can be deployed in order to promote the empowerment of women with a view to self-care and health promotion (AU).

Clinical study of intensity modulated radiotherapy and three-dimensional conformal radiotherapy with three-dimensional brachytherapy and concurrent chemotherapy for patients with advanced cervical cancer / 中华妇产科杂志

Objective To compare the dose, clinical efficacy and acute adverse reactions of intensity modulated radiotherapy(IMRT)and three-dimensional conformal radiotherapy(3D-CRT)combined with three-dimensional brachytherapy (3D-BT) in the treatment of concurrent radiotherapy and chemotherapy for advanced stage cervical cancer patients. Methods Data collection was performed from January 2011 to November 2015 in Chinese PLA General Hospital and Inner Mongolia Cancer Hospital.All 89 patients with advanced stage (Ⅱb-Ⅲb) cervical cancer were treated by pelvic radiotherapy and concurrent chemotherapy, 46 cases of them received IMRT and 3D-BT(IMRT group), 43 cases received 3D-CRT and 3D-BT(3D-CRT group),along with cisplatin chemotherapy.The dose accumulation of external beam radiotherapy and 3D-BT was calculated by deformable image registration to analyze clinical efficacy, acute adverse reactions and prognosis of the two groups.Results (1)Dose of radiotherapy:planning target volume(PTV)coverage of IMRT group and 3D-CRT group were respectively(95.4±4.7)% and(95.1±5.1)%, without significant differences (t=0.289, P=0.773). Compared with the patients treated with 3D-CRT, the volumn receiving at least 30 Gy (V30), V50of rectum, colon, bladder and small intestine and V20of bone marrow in the IMRT group were significantly decreased (P<0.05). Regarding the combined dose, the maximum dose (Dmax) and the minimum dose received by the most exposed 2 cm3volume of the analyzed organ(D2CC)of rectum,colon,bladder and small intestine of IMRT group were significantly lower than those of 3D-CRT group (P<0.05). (2) Short-term efficacy: the effective rate of IMRT and 3D-CRT group were respectively 93% (43/46) and 91% (39/43), with no significant differences (χ2=0.237,P=0.626). (3) Acute adverse reactions: compared with 3D-CRT, IMRT could significantly reduce grade 1-2 acute toxicity in gastrointestinal [63%(29/46) vs 84%(36/43)], genitourinary [17%(8/46) vs 37%(16/43)] and hematologic [57%(26/46) vs 79%(34/43)] system (all P<0.05). There were no significant differences of grade 3 acute adverse reactions of gastrointestinal,genitourinary and hematologic system between two groups(all P>0.05). No grade 4 acute adverse reactions were observed. (4) Prognosis: the overall survival rate at 1, 2-year of IMRT and 3D-CRT group were respectively 95.6%,89.1% and 93.1%,86.1%.The progression-free survival rateat 1, 2-year of IMRT and 3D-CRT group were 91.1%, 89.1% and 88.4%, 86.1%, respectively. There were no significant differences in overall survival rate and progression-free survival rate between two groups (P>0.05). Conclusions Compared with 3D-CRT, IMRT combined with 3D-BT has dosimetry advantages based on dose accumulation algorithms by deformable image registration. IMRT could ensure clinical efficacy and significantly reduce the incidence rate of acute toxicities.

Significance of p16/Ki-67 double immunocytochemical staining in cervical cytology ASCUS, LSIL,and ASC-H / 中华妇产科杂志

Objective To investigate the application value of p16/cell proliferation associated nuclear antigen (Ki-67) double-staining and human papillomavirus mRNA in the cytological screening.Methods Two hundred and fifty-one cases who suffered from atypical squamous cell of undetermined significance (ASCUS),low-grade squamous intraepithelial lesion (LSIL),atypical squamous cell-cannot exclude high-grade squamous intraepithelial lesion (ASC-H) in ThinPrep cytologic test (TCT) were collected in Peking University First Hospital between October 2015 and March 2016.And p16/Ki-67 double-staining and hybrid capture Ⅱ (HC-Ⅱ) detection were performed on the cervical cells.The result was compared with the pathological result of colposcope guided biopsy.All statistical analysis was completed by Stata 12.0 statistical software analysis.The results of diagnostic tests were described by using the sensitivity,specificity,positive predictive value,negative predictive value,and the area under the receiver operating characteristic (ROC) curve.Results (1) One hundred and eight cases of liquid based cytology diagnosis of ASCUS patients,the positive rate of p16/Ki-67 was 13.9％ (15/108),102 cases of liquid based cytology diagnosis of LSIL patients,the positive rate of p16/Ki-67 was 21.6％ (22/102),41 cases of liquid based cytology diagnosis of ASC-H patients,the positive rate of p16/Ki-67 was 39.0％ (16/41),compared amongthree groups,the difference was statistically significant (x2=78.516,P＜0.05);cervical exfoliated cells p16/Ki-67 expression rate was 13.0％ (28/215) in cervical low-grade lesions [cervical intraepithelial neoplasia (CIN)Ⅰ],which was 69.4％ (25/36) in high level lesions (CIN Ⅱ-Ⅲ),the difference was statistically significant (x2=7.932,P＜0.05).(2) The specificity of p16/Ki-67 detection and diagnosis were higher than those of HC-Ⅱ in ASCUS,LSIL,and ASC-H (89.8％ vs 71.4％,83.3％ vs 15.6％,88.9％ vs 40.7％;all P＜0.05),meanwhile,the positive predictive value of p16/Ki-67 detection and diagnosis exceed those of HC-Ⅱ in ASCUS,LSIL,and ASC-H (33.3％ vs 26.3％,31.8％ vs 12.6％,81.3％ vs 38.5％;all P＜0.05).Moreover,the ROC curve of p16/Ki-67 were bigger than those of HC-Ⅱ in ASCUS,LSIL,and ASC-H (0.799 vs 0.696,0.708 vs 0.531,0.909 vs 0.561;all P＜0.05).Conclusion For patients with cytological diagnosis of ASCUS,LSIL,and ASC-H,p16/Ki-67 double staining method could be used as an effective method to assist in the diagnosis of high-grade cervical lesions,and the screening efficiency is superior to that of high-rist HPV.
