Establishment and validation of a risk prediction model for high-grade cervical lesions.

OBJECTIVE: To establish and validate a risk prediction model for cervical high-grade squamous intraepithelial lesions (HSIL). METHODS: This retrospective study included patients who underwent cervical biopsies at the Cervical Disease Centre of Maternal and Child Hospital of Hubei Province between January 2021 and December 2021. RESULTS: A total of 1630 patients were divided into the HSIL + cervical lesion group (n = 186) and the ≤ LSIL cervical lesions group (n = 1444). LSIL, ASC-H, HSIL and SCC, high-risk HPV, HPV16, HPV18/45, multiple HPV strains, acetowhite epithelium, atypical vessels, and mosaicity were independently associated with HSIL + lesions. These factors were used to establish a risk prediction model with a demonstrated area under the curve (AUC) of 0.851 and a C-index of 0.829. Calibration curve analysis showed that the model performed well, with a mean absolute error (MAE) of 0.005. The decision curve showed that the model created by combining the risk factors was more specific and sensitive than each predictive variable. CONCLUSION: The model for predicting HSIL demonstrated promising predictive capability and might help identify patients requiring biopsy and treatment.

Liquid-Based Cytology in the Detection of Premalignant Lesions in Patients with "Atypia in Squamous Cells" in Conventional Cytology.

Background: The management of patients with "Atypical Squamous Cells" (ASC) in conventional papanicolaou smears (CPS) is based on the risk of high-grade squamous intraepithelial lesion (HSIL). The efficacy of liquid-based cytology (LBC) to detect this premalignant lesion is variable, with little evidence of its performance in Colombian patients. Aims: The aim of this study is to determine the performance of LBC in the detection of premalignant lesions, in patients with ASC in CPS. Materials and Methods: Were obtained patients who attended colposcopy clinic due the result of ASC in CPS. An LBC was taken, which was interpreted by two pathologists without access to other results. The performance of LBC to detect HSIL, was determined, considering as a gold standard: histopathological study/negative-satisfactory colposcopy. Results: Were included 114 patients, with a mean age of 38.4 years (SD ± 13.3). LBC had abnormal results in 40.36% (n = 46), with a slightly higher proportion of low-grade squamous intraepithelial lesion (LSIL) than HSIL. The total of abnormal diagnoses by colposcopy and/or biopsy was 51.75% (n = 59), with a predominance of LSIL (36.84%). The sensitivity of the liquid-based cytology to detect premalignant lesions was 76.5%, specificity: 66.0%, positive predictive value: 28.3% and negative predictive value: 94.1%; The Cohen's kappa index of LBC for detecting HSIL was 0.2492 for the total population and 0.2907 for ≥30 years. Discussion: Although LBC decreases abnormal cytology and increases the detection of HSIL, which improves diagnostic accuracy; sensitivity and predictive values for detecting HSIL are not significantly different between CPS and LBC.

Alterações em exames citopatológicos realizados em Unidade Básica de Saúde: um estudo analítico transversal / Alterations in cytopathological tests performed in a Basic Health Unit: a cross-cutting analytical study

Objetivo: Com o presente estudo, buscou-se verificar a quantidade de exames de colpocitologia oncótica coletados em Unidade Básica de Saúde (UBS) escolhida, determinar quantas e quais são as alterações encontradas nesses exames e quais foram as condutas e acompanhamentos realizados em pacientes com exames alterados. Métodos: Foram analisados 446 exames de colpocitologia oncótica realizados em uma UBS do centro-oeste do Paraná. As pacientes com exame alterado foram selecionadas e foi feita uma análise desses prontuários a fim de verificar a conduta e o acompanhamento dessas pacientes. Resultados: Foram encontrados 32 exames com alterações, sendo três de uma mesma paciente. Dessas 30 pacientes, a grande maioria correspondia a células escamosas atípicas de significado indeterminado (ASC-US), possivelmente não neoplásicas, e 28 pacientes retornaram para receber uma conduta inicial, sendo principalmente o encaminhamento para a coleta de novo preventivo em seis meses ao serviço de oncologia clínica. Conclusão: O presente estudo concluiu que a hipótese principal foi verdadeira, a qual foi descrita como prevalência significativa de lesões intraepiteliais de alto grau, embora não seja a mais frequente, e descontinuidade por parte das pacientes que obtiveram esse resultado. Além disso, notou-se grande encaminhamento à atenção terciária, o que não é indicado pelo Ministério da Saúde.(AU)

Objective: With the present study, we sought to verify the amount of cytopathological tests collected in the chosen basic health unit, to determine how many and what are the alterations found in these tests and what were the conducts and follow-ups performed in patients with altered exams. Methods: We analyzed 446 preventive tests performed in a basic health unit in the Midwest of Paraná, and patients with altered examination were selected and an analysis of these medical records was made in order to verify the conduct and follow-up of the patients. Results: Thirty-two tests with alterations were performed, 3 of which were the same patient. Of these 30 patients, the vast majority corresponded to atypical cells of squamous meaning ­ possibly non-neoplastic (ASC-US), and 28 patients returned to receive an initial approach, mainly being referred to the collection of preventive new in 6 months and to the clinical oncology service. Conclusion: The present study concluded that the main hypothesis was true, which was described as a significant prevalence of high-grade intraepithelial lesions (HSIL), although not the most frequent, and discontinuity on the part of the patients who obtained this result. In addition, there was a large referral to tertiary care, which is not indicated by the Ministry of Health.(AU)

Introdução: O diagnóstico precoce e referenciamento ao serviço especializado são essenciais para melhorar as taxas de cura e sobrevida das mulheres acometidas pelo câncer de colo de útero. Assim, a realização deste estudo tornará possível o levantamento de informações que serão essenciais para o desenvolvimento de medidas preventivas, que almejam contribuir com o desenvolvimento de ações de educação em saúde e o diagnóstico precoce para reduzir a morbimortalidade dessa enfermidade. Objetivo: Identificar o perfil dos resultados dos exames citopatológicos do colo do útero de mulheres residentes no estado de Minas Gerais a partir dos dados de exames correspondentes ao ano de 2019, utilizando as variáveis disponibilizadas pelo Sistema de Informação do Câncer. Métodos: Trata-se de um estudo retrospectivo, exploratório, quantitativo realizado por meio de base de dados secundários. Os dados foram submetidos à análise no software SPSS, versão 20.0. Realizou-se estatística descritiva (frequência absoluta, porcentagem, média e desvio padrão). Para verificar associação entre variáveis qualitativas foi utilizado teste qui-quadrado (x²) e exato de Fisher. A força das associações entre as variáveis foi aferida pelo risco relativo (RR) e intervalos de confiança (IC 95%). Resultados: As principais alterações presentes nos exames foram: alterações por células escamosas atípicas de significado indeterminado e lesão intraepitelial de baixo grau. Após análises estatísticas, notou-se que algumas alterações possuem risco maior de se desenvolverem no público fora da faixa etária preconizada, ou seja, entre mulheres com idade <25 anos ou >64 anos. Conclusão: O estudo realizado contribui para identificação do perfil atual vivenciado na área da saúde da mulher e possibilita a criação de condutas e ações que visem intervir frente aos resultados obtidos, impactando positivamente na realidade de Minas Gerais

Introduction: Early diagnosis and referral to a specialized service are essential to improve the cure and survival rates of women affected by cervical cancer. Thus, carrying out this study will make it possible to collect information that will be essential for the development of preventive measures, which aim to contribute to the development of health education actions and early diagnosis to reduce the morbidity and mortality of this disease. Objective: Identify the profile of the results of cervical cytopathological examinations of women residing in the State of Minas Gerais from the data of examinations corresponding to the year 2019, using the variables made available by the Cancer Information System.Methods: This is a retrospective, exploratory, quantitative study carried out by means of a secondary database. The data were submitted to analysis using the SPSS software, version 20.0. Descriptive statistics (absolute frequency, percentage, mean and standard deviation) were performed. To verify the association between qualitative variables, the chi-square test (x²) and Fisher's exact test were used. The strength of the associations between the variables was measured by the relative risk (RR) and confidence intervals (95% CI). Results: The main alterations present in the cytopathological exams performed were: changes due to atypical squamous cells of undetermined significance and low- grade intraepithelial lesion. After statistical analysis, it was noted that some changes have a higher risk of developing in the public outside the recommended age range, that is, among women aged <25 years or> 64 years. Conclusion: The study carried out contributes to the identification of the current profile experienced in the area of women's health and enables the creation of conducts and actions that aim to intervene in view of the results obtained, positively impacting the reality of Minas Gerais.

Can biopsies be omitted after normal colposcopy in women referred with low-grade cervical cytology? A prospective cohort study.

BACKGROUND: Controversy surrounds whether women with low-risk cytology screening results but a normal colposcopic assessment should have random biopsies taken. The aim of this study was to determine the yield of CIN2+ from one to four cervical biopsies in women with cytology of LSIL or ASCUS and a normal colposcopic impression. METHODS: Between January 2017 and September 2020, women over 18 years old referred for colposcopic examination due to either an abnormal smear (ASCUS+) or follow-up after previous cervical intraepithelial neoplasia (CIN) were invited to participate in the study. All study participants underwent colposcopic examination and had four biopsies taken. The biopsies were analyzed separately. RESULTS: In total, 1327 women with abnormal cervical cancer screening results or attending follow-up after a previous CIN diagnosis were enrolled in the study and examined by colposcopy. Of these, 173 were newly referred with cytology of LSIL or ASCUS and had a normal colposcopic impression and four adequate biopsies. Of these, 22.0% were diagnosed with CIN2+. When combining the results of the four biopsies, we found a 100% relative increase in CIN2+ cases compared to using only one biopsy (from 11.0% to 22.0%, P = 0.006). CONCLUSION: As we found CIN2+ from random cervical biopsies in 22.0% of women with cytology of LSIL or ASCUS who had a normal colposcopic impression, we advocate performing four random cervical biopsies at the squamocolumnar junction in such women. Trial registration NCT04249856, January 31 2020 (retrospectively registered).

Comparison between Urine and Cervical High-Risk HPV Tests for Japanese Women with ASC-US.

Most uterine cervical cancers are caused by the persistent infection of the high-risk human papillomavirus (hrHPV). Thus, the hrHPV-DNA test, which examines specimens from the cervix, is the standard screening method as well as cytology in western countries. Urine sampling for the hrHPV-DNA test would be easier and help improving screening rates. This study prospectively investigated the concordance between urine and cervical hrHPV tests for patients with atypical squamous cells of undetermined significance (ASC-US) in cervical cytology. We recruited 338 women with the cytologic diagnosis of ASC-US and performed hrHPV-DNA tests to both samples from the uterine cervix and first void urine, using the Cobas 4800 system. In all hrHPV genotypes, the simple concordance rate was 90.8% (307/338) and the Kappa statistic value was 0.765, which shows substantial concordance. The positive concordance rate was 70.5% (74/105), which was the rate excluding women who had negative results in both tests. When limited to types 16 and 18, the simple concordance rate was 98.8% (334/338), and the Kappa statistical value was calculated to be 0.840, which showed almost perfect concordance. The positive concordance rate resulted in 81.8% (18/22). We conclude that the urine hrHPV-DNA test could substitute the cervical test in women with ASC-US.

Impacto da estrogenização vaginal no seguimento de citologia oncótica de significado indeterminado na pós-menopausa / Impact of vaginal estrogenization in follow-up of oncotic cytology of undetermined significance in postmenopausal women

Avaliar a estrogenização tópica vaginal no seguimento de citologia oncótica de significado indeterminado, tipo ASC-H, na pós-menopausa. Estudo, tipo caso-controle, que avaliou mulheres menopausadas com diagnóstico de ASC-H, divididas em dois grupos, com e sem uso de estrogênio tópico vaginal (GE e GNE). Foi calculada razão de chance a partir de tabelas de contingência construídas com variação robusta. Foram analisados 128 prontuários, sendo 27% de pacientes do GNE e 72% do GE. Houve aumento de diagnósticos ASC-H no GNE. No GE, aproximadamente 68 vezes menos colposcopias inadequadas e diminuição do número de colposcopias e Cirurgia de Alta Frequência (CAF), com evidência na redução em 21 e 12,5 vezes, respectivamente. Diminuição do número de colposcopias com melhor adequação ao exame, número de biópsias inalterado e diminuição do número de cirurgias de alta frequência, no grupo com uso de estrogênio tópico vaginal durante o seguimento.

Current paper evaluates topic vaginal estrogenization following oncotic cytology of undetermined significance, type ASC-H, in postmenopausal women. A case-control study evaluated menopausal women diagnosed with ASC-H, divided into two groups, with and without the use of topic vaginal estrogen (GE and GNE). Odds ratios were calculated from contingency tables built with robust variation. 128 medical records were analyzed, 27% of which were from the GNE and 72% from the GE. There was an increase in ASC-H diagnoses in GNE. In GE, approximately 68 times less inappropriate colposcopies and a decrease in the number of colposcopies and High Frequency Surgery (HFS), with a reduction of 21 and 12.5 times, respectively. Decrease in the number of colposcopies with better adaptation to the exam, unchanged number of biopsies and decrease in the number of high-frequency surgeries, in the group using topic vaginal estrogen during the follow-up.

Psychosocial impact of inclusion of HPV test on the management of women with atypical squamous cells of undetermined significance: a study within a randomised pragmatic trial in a middle-income country.

Objective: To assess the psychosocial impact of human papillomavirus (HPV) testing, colposcopy, and Pap-smear, as triage strategies after a Pap-smear with atypical squamous cells of undetermined significance (ASCUS). We also sought to evaluate the psychosocial impact based on the results of the strategies. Methods: Nested within a randomised pragmatic trial, which compared an immediate colposcopy, repeat Pap-smear, and high risk HPV test, we enrolled 675 women between 2012 and 2014. Participants completed surveys at enrollment, two weeks after triage test results, and 1 year thereafter to assess cervical cancer and HPV knowledge, self-esteem, anxiety and HPV impact (HIP). Results: Knowledge, self-esteem, anxiety and HIP improved with no differences among arms. At the baseline, 31.4% and 32.7% of the participants had state anxiety and trait anxiety, respectively, which decreased to 10.7% and 13.3% in the last survey. Compared to HPV-negative women, HPV-positive women in the second survey had worse HIP scores (HPV-: M 22.9 [SD: 15.20]; HPV+: M 35.9 [SD: 19.91]; p < 0.001), trait anxiety (HPV-: M 15.4 [SD 12.73]; HPV+: M 22.9 [SD 13.29]; p = 0.001), and state anxiety (HPV-: M 10.7 [SD 11.25]; HPV+: M 21.4 [SD 14.81]; p < 0.001). Conclusions: HPV testing as a triage strategy for women with ASCUS does not differ from colposcopies or Pap-smears in terms of psychosocial outcomes.

The effect of an animation video on consultation time, anxiety and satisfaction in women with abnormal cervical cytology: Animation video reduces colposcopy time.

The objective was to assess whether supplementing hospital-dependent standard information with a hospital-independent animation video might reduce consultation time, pre-colposcopy anxiety levels and increase post-colposcopy satisfaction. Between November 2016 and May 2018, women were included if they were referred to the department of Obstetrics and Gynaecology in one of the three participating hospitals in the Netherlands due to an abnormal cervical smear. Exclusion criteria were colposcopy in the medical history or inability to understand, speak or read Dutch. Two consecutive cohorts were created: a control group that received standard information and an intervention group that received the same plus the animation video. Outcome measures were consultation time, pre-colposcopy anxiety level and post-colposcopy satisfaction. Consultation time was measured using stopwatch. Anxiety was measured using the State-Trait Anxiety Inventory (STAI) and the Hospital Anxiety and Depression Scale (HADS). Satisfaction was measured with the Patient's Experience and Attitude Colposcopy Eindhoven questionnaire (PEACE-q). In total, 122 women were included, 61 in each group. Baseline characteristics were similar between the two groups. Pre-colposcopy consultation time was significantly reduced in the intervention group (median 140 s) compared to the control group (median 269 s). However, overall consultation time was not reduced. The outcome measures anxiety and satisfaction were not significantly different. A hospital-independent animation video did significantly reduced pre-colposcopy consultation time but did not reduce anxiety or increase satisfaction in women with abnormal cervical cytology. Further research should focus on the effects of animation video in a primary care setting.

Hallazgos en colposcopia. Experiencia en una unidad de referencia / Findings in colposcopy. Experience in a reference unit

Resumen OBJETIVO: Describir los desenlaces colposcópicos de pacientes con alteraciones citológicas atendidas en una institución colombiana. MATERIALES Y MÉTODOS: Estudio observacional, trasversal y retrospectivo al que se incluyeron pacientes a quienes se tomó una colposcopia, indicada por reporte anormal en la citología (2012-2106). La muestra se seleccionó a partir de un muestreo aleatorio, estratificado por grupos etarios. Se establecieron las frecuencias de las alteraciones colposcópicas y de los reportes histológicos. RESULTADOS: Se incluyeron 372 pacientes. La principal indicación de la colposcopia fue el reporte de atipia de células escamosas de significado indeterminado (70.6%), seguido por lesiones intraepiteliales de bajo grado (16.9%) y pólipos endocervicales (2.9%). La colposcopia fue negativa en 32% de los casos, positiva en 31% y con inflamación en 21%. El resto de los casos correspondió a atrofia o pólipos. De las colposcopias positivas, el principal reporte fue de cambios menores o grado 1; sobre todo en las pacientes de 15 a 24 años. De las pacientes con biopsia se reportó un caso de adenocarcinoma (3.1%) y otro de carcinoma in situ (3.1%) en el mismo grupo etario. CONCLUSIÓN: La colposcopia identificó lesiones de alto y bajo grado clínicamente no significativas. La colposcopia es una herramienta decisiva para el diagnóstico de lesiones premalignas del cuello uterino.

Abstract OBJECTIVE: This study describes the colposcopic results of patients with cytological alterations in a Colombian institution. MATERIALS AND METHODOS: Observational Cross-sectional study based on retrospective data. Patients who underwent colposcopy due to abnormal cytologies during 2012-2106 were included. A stratified random sampling was carried out by age groups. The frequencies of colposcopic alterations and histological results were established. RESULTS: 372 patients were selected. The main indication for colposcopy was the ASCUS report (70.6%), followed by LSIL (16.9%) and endocervical polyps (2.9%). Colposcopy was negative in 32% of the cases, positive in 31% and inflammation in 21%. The rest of cases corresponded to varied findings such as atrophy or polyps. Of the positive colposcopies the main report was minor changes or grade 1; especially in patients between 15-24 years. Of the patients with a biopsy, one case of adenocarcinoma (3.1%) and another of carcinoma in situ (3.1%) were reported in the same age group. CONCLUSIONS: The realization of colposcopy identified the high-grade lesions in this population, but also detected clinically insignificant low-grade lesions. Colposcopy is a key tool for the diagnosis of premalignant lesions of the cervix.

Atypical Squamous Cells: Cytopathological Findings and Correlation with HPV Genotype and Histopathology.

OBJECTIVE: We aimed to assess potential associations between atypical squamous cell (ASC) subgroups: ASC-US (undetermined significance) and ASC-H (cannot exclude high-grade squamous intraepithelial lesion), regarding cytomorphological features, high-risk (HR) human papillomavirus (HPV) testing, and histological outcomes in a sample of Brazilian women. STUDY DESIGN: Cross-sectional study which evaluated 1,346 liquid-based cytologies between January 2010 and July 2016 with ASC results. ASC-US and ASC-H were analyzed for frequency, diagnostic criteria, and cytological findings and compared with HR-HPV tests and histological outcomes. RESULTS: Enlarged nucleus was the most frequent ASC-US criterion, but alternative criteria were present in 20% of the total cases. No ASC-US criteria were associated with histological outcomes or HR-HPV positivity. Parakeratosis, corneal pearl, giant cells, and binucleation were strongly associated with ASC-US while hyperkeratosis was associated with high-grade squamous intraepithelial lesions (HSIL) or a superior outcome. HR-HPV was positive in 64.39% of ASC-US and 65.38% of ASC-H. HSIL or superior outcomes also occurred in 13.33% of ASC-US and 64.71% of ASC-H cases. CONCLUSION: Alternative criteria for ASC-US were relatively frequent. Reactive cellular changes suggestive of atypias were more abundant in ASC-US. Although ASC-H is associated with worse histological outcomes, no differences in HPV positivity were found in comparison to ASC-US.

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.

Incidencia y caracterización de pacientes con células escamosas atípicas de significado indeterminado / Incidence and Characterization of Patients with Atypical Squamous Cells of Undetermined Significance

Fundamento: el estudio citológico es el más importante en los programas de detección precoz de cáncer cervicouterino, siendo la atipia de células escamosas de significado indeterminado la anomalía más frecuente encontrada. Objetivo: determinar la incidencia de atipia de células escamosas de significado indeterminado en la consulta de patología de cuello del Hospital Universitario Ginecobstétrico Mariana Grajales de la provincia Villa Clara. Método: se realizó un estudio de tipo transversal en el que el universo estuvo constituido por las 206 pacientes remitidas a la consulta de patología de cuello durante el año 2011, la muestra fue de 120 mujeres que en el libro de registro de citologías orgánicas del departamento de anatomía patológica del Hospital, contaban con la totalidad de los datos requeridos con un reporte de células escamosas atípicas de significado indeterminado. Las variables estudiadas fueron: edad en años cumplidos al momento del diagnóstico, la edad en años de las primeras relaciones sexuales y el número de partos. Se confeccionó un fichero de datos en Excel donde se realizaron los cálculos necesarios. Se emplearon números absolutos y porcentajes para resumir las variables cualitativas y media, desviación estándar, valores mínimos y máximos para las cuantitativas. Resultados: se obtuvo una incidencia de células escamosas atípicas de significado indeterminado de un 0,37 %, predominó en las mujeres mayores de 40 y menores de 50 años, la mayoría inició sus relaciones sexuales antes de los 20 años y tuvieron 2 hijos. Conclusión: la incidencia de reportes de células escamosas atípicas durante el período de tiempo estudiado fue baja, predominó en mujeres de mediana edad, en aquellas que iniciaron sus primeras relaciones sexuales de manera precoz y en las multíparas.

Foundation: cytological study in the most important of the programs for early detection of cervical uterus cancer. The most frequently atypia found was squamous cells of undetermined significance. Objective: to determine the incidence of squamous cells of undetermined significance in the consultation of Cervix Pathology at the Gyneco-Obstetric University Hospital Mariana Grajales. Method: it was a cross-sectional study in a universe constituted by the 206 patients referred to the cervix pathology consultation during the year 2011. The sample was 120 women from the organic cytology registration book at the pathological anatomy department of the Hospital, who had all the required data with a report of atypical squamous cells of undetermined significance. The studied variables were: age in years completed at the time of diagnosis, age in years of the first sexual relations and the number of births. A data file was created in Excel where the necessary calculations were made. Absolute numbers and percentages were used to summarize the qualitative and average variables, standard deviation, minimum and maximum values for the quantitative variables. Results: an incidence of atypical squamous cells of undetermined significance of 0.37 % was obtained, it predominated in women older than 40 and younger than 50 years old and most of them started their sexual relations before the age of 20 and had 2 children. Conclusion: the report incidence of atypical squamous cells during the studied period of time was low; it predominated in middle-aged women, in those who had an early sexual relation and in multiparous women.

[Significance of p16/Ki-67 double immunocytochemical staining in cervical cytology ASCUS, LSIL, and ASC-H].

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 (χ(2)=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 (χ(2)=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.

Caracterización de lesiones intraepiteliales en mujeres del cantón Penipe, Ecuador. Noviembre 2014 / Characterization of intraepithelial lesions in women of Penipe town, Ecuador. Novem-ber 2014

El proceso investigativo tuvo un enfoque cuantitativo, de tipo observacional, descriptivo, transversal; con el propósito de caracterizar las lesiones intraepiteliales en 100 pacientes del cantón Penipe, con edades comprendidas entre 20 a 65 años, que asistieron a consulta gineco-lógica del Centro de Erradicación del Bocio y Capacitación a Minusválidos (CEBYCAM), durante el mes de noviembre de 2014. Los datos fueron obtenidos empleando la técnica de la medición, a través del empleo del Sistema Internacional de Reporte de Bethesda. El prome-dio de la edad fue 41.44 años (± 13.60); la media aritmética de la edad de inicio de las relacio-nes sexuales fue de 16,37 (± 4.49); predominaron las mujeres con dos hijos, aquellas cuyo test resultó negativo (88 %) y las que no utilizaban algún método anticonceptivo, así como para la presencia de microorganismos con potencial patológico. La prueba de correlación de Pearson arrojó la existencia de una relación fuerte y positiva entre las variables paridad y edad.

The researching process had a quantitative, observational, descriptive, cross-sectional approach. It aimed to characterize the intraepithelial lesions in 100 patients from Penipe town, aged between 20 and 65 years, who are treated at the gynecological consultation of Centro de Erradicación del Bocio y Capacitación a Minusválidos during the month of November 2014. The data were obtained through the use of the Bethesda International Reporting System measurement technique. The age was on average 41.44 (± 13.60); the arithmetic mean of the age of onset of sexual intercourse was 16.37 (± 4.49); women with two children predominated, those whose test was negative (88%) and those who did not use any contraceptive method, as well as the presence of microorganisms with pathological potential. The Pearson correlation test showed the existence of a strong and positive relationship between parity and age variables.

[Influence of Age in the Prevalence of High-Risk Human Papiloma Virus in Women with Pre-Neoplasic Cervical Lesions in Navarra, Spain]. / Influencia de la edad en la prevalencia de virus de papiloma humano de alto riesgo en mujeres con lesiones precursoras de cáncer de cuello uterino en la Comunidad Navarra.

OBJECTIVE: Cervical carcinoma (CC) is the second cause of death among women aged 15 and 44 in Spain. CC is linked to hig-risk human papillomavirus (HR-HPV) infection and its prevalence varies according age and geographical region. The awereness of the latter is essential for public health prevention efforts. The aim was to study the age related in HR-HPV genotypes in cytologies with squamous intraepithelial lesion (SIL). METHODS: From a total of 67,935 ginecologic cytologies over a four-year period, we selected cytologic specimens with SIL. We used the Cervista® test to detect HR-HPV DNA. Women were classified into two groups under 35 and over 35 years old. Proportions were estimated with confidence intervals at 95% (95% CI). RESULTS: HR-HPV prevalence was 59,7%; 64,6% in women under 35 years old. HR-HPV species alpha 9 type 16 (HR-HPV 16) and alpha 5 type 51 (HR-HPV 51) were the most prevalent (60,9% and 51,7%). High-grade squamous intraepithelial lesions (H-SIL) were twice as high in women under 35 years (6,5 vs. 3,7%). 88,8% of H-SIL was associated HR-HPV 16, which increases the probability of H-SIL against Low-grade squamous intraepithelial lesions (L-SIL) regardless of age. CONCLUSIONS: In our population HR-HPV 16 was associated to H-SIL whereas HR-HPV specie alpha 7 type 18 and HR-HPV 51 to L-SIL regardless of age. The high prevalence of HR-HPV 51 in Navrra´s population (51,7%), suggests that local vaccination programs be re-assessed.

El cáncer de cuello uterino (CCU)es la segunda causa de muerte en España en mujeres entre 15 y 44 años. Esta ligado íntimamente a la infección por el virus del papiloma humano de alto riesgo (VPH-AR). La prevalencia del VPH-AR incrementa según la gravedad de la lesión, grupo etario y región geográfica cuyo conocimiento es esencial para el desarrollo de estrategias de prevención. El objetivo fue determinar la influencia de la edad de las mujeres (menores o mayores de 35 años) en relación con la especie de VPH-AR presente y la lesión escamosa intraepitelial (LEI).

[Expression of TREM-1 in patients with invasive cervical cancer and precursor lesions]. / Expresión de TREM-1 en pacientes con cáncer cervical invasor y lesiones precursoras.

BACKGROUND: It has been shown that the TREM-1 glycoprotein belongs to the immunoglobulin superfamily that induces secretion of various proinflammatory cytokines. The aim of this study was to measure the expression of TREM-1 in patients with cervical cancer. METHODS: In this cross-sectional study we included four groups of patients: GI: women with low-grade squamous intraepithelial lesion (IL) (n = 15 p / g); GII: patients with high-grade squamous IL (n = 9 w / g); GIII: patients with invasive cervical cancer (n = 9 p / g) and GIV: healthy patients (n = 15 p / g). In all patients the expression of TREM-1 and the Average Fluorescence Index (AFI) in neutrophils and monocytes were measured, as well as levels of leukocytes, neutrophils and monocytes. We used Student's t test for independent samples. For these variables, we applied Mann-Whitney rank-sum, ANOVA, and Tukey tests. Chi square test was used for qualitative variables. RESULTS: The percentages of TREM-1 expression in neutrophils and monocytes, plus the AFI in neutrophils in the 4 groups was not significantly different. The AFI of TREM-1 in monocytes was significantly different when comparing group II and group III versus group IV (p < 0.02). There was also no significant difference when comparing the mean values of leukocytes, neutrophils and monocytes in the different groups. CONCLUSION: This study shows increased expression of TREM-1 in monocytes from patients with advanced cancer.

Introducción: se ha demostrado que la glicoproteína TREM-1 pertenece a la superfamilia de las inmunoglobulinas que induce la secreción de varias citocinas proinflamatorias. El objetivo de este trabajo fue medir la expresión de TREM-1 en pacientes con cáncer cervical. Métodos: en este estudio transversal analítico incluimos 4 grupos de pacientes: GI: mujeres con lesión intraepitelial (LI) escamosa de bajo grado (n = 15 p/g); GII: pacientes con LI escamosa de alto grado (n = 9 p/g); GIII: pacientes con cáncer cervical invasor (n = 9 p/g), y GIV: pacientes sanas (n = 15 p/g). En todas las pacientes se midió la expresión de TREM-1 y el Índice Medio de Fluorescencia (IMF) en neutrófilos y monocitos, así como los niveles de leucocitos, neutrófilos y monocitos. Usamos t de Student para muestras independientes. Para estas mismas variables, aplicamos prueba de suma de rangos de Mann-Whitney, ANOVA y Turkey. Para las variables cualitativas se utilizó la prueba de Chi cuadrada. Resultados: los porcentaje de expresión de TREM-1 en neutrófilos y monocitos, además del IMF en neutrófilos en los 4 grupos, no fue significativamente diferente. El IMF de TREM-1 en monocitos fue significativamente diferente al comparar el grupo II y grupo III frente al grupo IV (p < 0.02). Tampoco hubo diferencia significativa al comparar los valores promedio de leucocitos, neutrófilos y monocitos en los diferentes grupos. Conclusión: este estudio documenta una mayor expresión de TREM-1 en monocitos de pacientes con cáncer avanzado.

Impact of age on the false negative rate of human papillomavirus DNA test in patients with atypical squamous cells of undetermined significance.

OBJECTIVE: Human papillomavirus (HPV) test was incorporated into the triage of lesser abnormal cervical cytologies: atypical squamous cells of undetermined significance (ASCUS) or low-grade squamous intraepithelial lesion (LSIL). This study aimed to evaluate the impact of age on the efficacy of HPV testing in patients with lesser abnormal cervical cytologies. METHODS: A total of 439 patients with ASCUS or LSIL were included. The association between age groups and the diagnostic performances of HPV test for high-grade cervical intraepithelial neoplasia (CIN2+) was evaluated. RESULTS: Median age was 44 years (range, 17 to 75 years). ASCUS was more frequently observed in older patients while LSIL was more common in younger patients (P=0.002). CIN2+ was found in 11.3% (32/284) of the ASCUS patients and 12.9% (20/155) of patients with LSIL. Older patients with ASCUS showed lower HPV infection rates (P=0.025), but not LSIL (P=0.114). However, the prevalence of CIN2+ was similar between the age groups with ASCUS or LSIL. In patients with ASCUS, the false negative rate of HPV test for CIN2+ was 6.2%. The false negative rate of the HPV test became higher with increasing of the age after the age of 50 (P=0.034). CONCLUSION: Our findings suggest that false negative rate of the HPV test for CIN2+ in ASCUS patients older than 50 years might become higher with increasing of the age. Negative HPV results in patients of the age >50 years with ASCUS should be carefully interpreted.
