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)

Conclusiones: La infección por VPH es un factor de riesgo importante para el desarrollo de lesiones intraepiteliales de alto grado a 2, 5 y 10 años.

Abstract Introduction: Cervical cancer is the second in frequency and the third in mortality, infection by the human papillomavirus (HPV) is associated with the risk of increased cancer; however, the cumulative risk of 1, 2, 3, 5 and 10 years is not known. Objective: To determine the risk of HPV-positive patients with negative initial cytological evaluation for developing high-grade intraepithelial lesion over time. Method: A systematic review of articles in English and Spanish in the last 20 years was carried out, using the PubMed, Cochrane, LILACS, ProQuest and Embase databases. Randomized clinical trials were included in which HPV was performed and subsequent follow-up with cervicovaginal cytology at 1, 2, 3, 5 and 10 years in women aged 20-64 years. Results: Seven randomized clinical trials were included, a total of 98,521 women, 8820 with positive HPV and 89701 negative on admission and followed up for up to 10 years with cervicovaginal cytology. Finding that HPV infection is a risk factor for developing high-grade intraepithelial lesion at 2, 5 and 10 years with a relative risk of 110.94 (79.41-154.97), 83.65 (55.22- 126.73) and 29.71 (5.72-154.33), respectively. Conclusions: HPV infection is an important risk factor for the development of high-grade intraepithelial lesion at 2, 5 and 10 years.

Hybrid capture as a tool for cervical lesions screening in HIV-infected women: insights from a Brazilian cohort

ABSTRACT Introduction: Cervical cancer remains an important burden for HIV-infected women in the era of combination antiretroviral therapy. Recommendations for cervical screening in these women diverge and may include high-risk HPV (HRHPV) testing. We aimed to evaluate the clinical usefulness of a single HRHPV testing for cervical screening of HIV-infected women. Methods: 723 HIV-infected women from a Brazilian prospective cohort were included between 1996 and 2012. Inclusion criteria were: normal cervical cytology at baseline and having a HRHPV-test at baseline. We calculated incidence rates of any squamous intraepithelial lesion (SIL) and high grade SIL+ (HSIL+) and negative predictive values (NPV) within 12 and 36 months. Hazard Ratios were obtained using Cox proportional hazards regression models. Results: Incidence rate for both outcomes was low (9.9 cases per 100 PY [95% CI 8.8-11.0] for any SIL and 1.3 cases per 100 PY [95% IC 0.9-1.8] for HSIL+). Women with a HRHPV positive status at baseline had 1.7-fold (95% CI 1.3-2.2) and 3.2-fold (95% CI 1.5-7.1) increased risk of presenting any SIL and HSIL+, respectively, during follow-up. Negative-HRHPV test presented high NPV for both periods and outcomes (any SIL: 92.4% [95% CI 89.7-94.6] for 12 months and 80.9% [95% CI 77.2-84.3] for 36 months; and HSIL+: 99.8% [95% CI 98.9-100.0] for 12 months and 99.0 [95% CI 97.6-99.7] for 36 months). Conclusions: Incidence of any and high grade cytological abnormality was significantly higher among HIV-infected women with positive-HRHPV test. A single negative-HRHPV test helped reassure follow-up free of cytological abnormalities through three years of follow-up in HIV-infected women with negative cytology.

Bonafide, type-specific human papillomavirus persistence among HIV-positive pregnant women: predictive value for cytological abnormalities, a longitudinal cohort study

This study investigated the rate of human papillomavirus (HPV) persistence, associated risk factors, and predictors of cytological alteration outcomes in a cohort of human immunodeficiency virus-infected pregnant women over an 18-month period. HPV was typed through L1 gene sequencing in cervical smears collected during gestation and at 12 months after delivery. Outcomes were defined as nonpersistence (clearance of the HPV in the 2nd sample), re-infection (detection of different types of HPV in the 2 samples), and type-specific HPV persistence (the same HPV type found in both samples). An unfavourable cytological outcome was considered when the second exam showed progression to squamous intraepithelial lesion or high squamous intraepithelial lesion. Ninety patients were studied. HPV DNA persistence occurred in 50% of the cases composed of type-specific persistence (30%) or re-infection (20%). A low CD4+T-cell count at entry was a risk factor for type-specific, re-infection, or HPV DNA persistence. The odds ratio (OR) was almost three times higher in the type-specific group when compared with the re-infection group (OR = 2.8; 95% confidence interval: 0.43-22.79). Our findings show that bonafide (type-specific) HPV persistence is a stronger predictor for the development of cytological abnormalities, highlighting the need for HPV typing as opposed to HPV DNA testing in the clinical setting.

Protocolo para la pesquisa de la displasia anal mediante citología y anoscopía de alta resolución / Protocol for the investigation of anal dysplasia by cytology and high resolution anoscopy

Introducción: El carcinoma anal escamoso (CAE) representa el 2% de todas las neoplasiascolorrectoanales. Afecta a 2/100.000 habitantes por año en la población general. Se incrementa en lospacientes con serología positiva para el virus de la inmunodeficiencia humana (VIH-positivos), 60/100.000habitantes por año y asciende a 92-144/100.000 habitantes por año en los hombres que tienen sexocon hombres (HSH) VIH-positivos. Al igual que en el carcinoma escamoso del cuello uterino, el virus delpapiloma humano (VPH) está implicado en su génesis, y se encuentra presente en el 92% de los casos.El cáncer cervical y anal comparten el mismo origen embriológico, formando la zona de transformación,sitio donde se desarrollan las lesiones intraepiteliales escamosas (SIL) como resultado de la infección ypersistencia del VPH, en especial de los genotipos de alto riesgo que pueden progresar a CAE invasor. Elaumento significativo de CAE en las últimas décadas ha llevado a desarrollar la pesquisa de SIL anal (ASIL)mediante citología (PAP) y anoscopía de alta resolución (AAR) con técnica colposcópica, emulando losprotocolos de detección temprana para prevención el cáncer de cuello uterino.Objetivo: Conocer prevalencia de lesiones precursoras del CAE.

Introduction: Anal squamous cell carcinoma (SCC) represents 2% of all colo-recto-anal malignancies. It is confirmed a higher rate of anal cancer among HIV-infected population in comparison with the HIVuninfected population (60/100,000 person-years, versus 2/100,000 person-years). Among HIV-infected men who have sex with men (MSM), the incidence of anal cancer is as high as 92-144/100,000 population. Like cervical cancer, squamous-cell canal cancer is caused predominantly by high-risk, oncogenic strains of human papillomaviruses (HPV) detected in 92% of HIV-positive MSM. The cervical and anal cancer share the same embryological origin, and occurs at a squamo-columnar transition zone, site of squamous intraepithelial lesions (SIL) as a result of the persistence HPV infection, especially the high-risk genotypes that may progress to invasive cancer. In the last decades, the incidence of squamous-cell anal carcinoma is increasing rapidly forcing the research of anal SIL (ASIL) cytology (PAP) and high-resolution anoscopy (HRA) colposcopic technique, emulating protocols for early detection of cervical cancer as a primary prevention. Objective: This study aimed to determine the prevalence of SCC precursor lesions. Determine sensitivity (S), specificity (Sp), positive predictive value (PPV) and negative predictive value (NPV) for the detection of anal dysplasia in the risk population. Material and Methods: Design prospective, cross-sectional, observational, analytical study. High-risk patients (HIV-positive MSM, patients with history of anogenital HPV, women with history of cancer or lower genital intraepithelial neoplasia) were included consecutively between April 2012 and February 2014 in Anal Early Detection Cancer Clinic...

Follow-up of women with inadequate Pap smears: a prospective cohort study / Acompanhamento de mulheres com esfregaços de Papanicolaou inadequados: um estudo prospectivo de coorte

CONTEXT AND OBJECTIVE: Inadequate Pap smears do not provide satisfactory cell samples for evaluation, thus making it more difficult to detect cervical cytological abnormalities. The objective of this study was to determine the cytological and histological follow-up results from women with inadequate smear reports in primary healthcare centers in Santiago, Chile 2010-2011. DESIGN AND SETTING: Prospective cohort study at primary healthcare clinics in Santiago, Chile. METHODS: The population was taken from the “Cito-Expert" database of 2010. The data were then organized according to the cytological and histological follow-up results of 2,547 women with inadequate cervical cytological reports over the 12-month period. The samples were assigned to groups based on the cause of inadequacy (smears with endocervical cells alone; insufficient, hemorrhagic, inflammatory or poorly fixed samples; insufficient and hemorrhagic samples; or insufficient and inflammatory specimens). The data were analyzed using the “conditional probability tree diagram" and descriptive statistics. RESULT: Half of the women (n = 1,285) met the requirements of the Ministry of Health for repeating these inadequate smears, and 1,104 of these women had normal cytological results (85.9%). The detection rate for cervical lesions according to group ranged ...

Prevalência de alterações citológicas anais em pacientes com citologia cervical anormal / Prevalence of cytological anal abnormalities in patients with abnormal cervical cytology

A incidência do carcinoma escamoso anal vem crescendo expressivamente. Principal fator associado a ele é o Papiloma Vírus Humano (HPV). Estudos epidemiológicos mostram fases pré-clínicas antes do início do câncer anal. Esse trabalho visou a estimar a prevalência de alterações citológicas anais em pacientes com citologia cervical anormal e sem lesão macroscópica HPV induzida na região anal. Foram selecionadas 70 mulheres com citologia cervical alterada, soronegativas para o Vírus da Imunodeficiência Humana (HIV) e sem lesão perianal macroscópica pelo HPV. As pacientes foram submetidas a um questionário e foram realizadas coletas de captura híbrida anal e cervical, bem como de uma amostra de citologia oncológica cervical e duas amostras anais. A prevalência das alterações citológicas anais encontrada foi de 71,4%, sendo que 57,1% apresentaram captura híbrida anal positiva. A prevalência de captura híbrida anal positiva para HPV de alto risco oncogênico em paciente com citologia cervical de atipia escamosa de significado indeterminado, provavelmente não neoplásico (ASC-US) e de lesão intraepitelial escamosa de baixo grau (LSIL) foi de 27,1% e, em pacientes com citologia cervical de atipia escamosa de significado indeterminado, não podendo excluir lesão intraepitelial de alto grau (ASC-H), lesão intraepitelial escamosa de alto grau (HSIL), e carcinoma epidermóide do colo do útero foi de 30%. Pacientes com captura cervical positiva tiveram 4 vezes mais chance de apresentar captura anal positiva (OR=4; p=0,018). Concluímos haver alta prevalência citológica anal alterada na população estudada. O risco de contaminação anal é significativo nas pacientes com HPV de alto poder oncogênico em cérvice, portanto todas as pacientes com citologia cervical anormal merecem investigação anal, independente da gravidade do laudo citológico

The incidence of anal squamous cell carcinoma has been growing significantly. The main risk factor associated with this injurie is the Human Papilloma Virus (HPV). As studies have shown preclinical stages before the onset of anal cancer. This study aimed to estimate the prevalence of anal cytological abnormalities in patients with abnormal cervical cytology and without macroscopic HPV induced lesions in the anal region. The sample consisted of 70 women with abnormal cervical cytology, seronegative for human immunodeficiency virus (HIV) and without macroscopic anal lesions. Patients answered a questionnaire a were submited to collection of anal and cervical hybrid capture assay and collection of a sample of cervical cytology of two anal samples. Prevalence of anal cytological abnormalities found in patients with cervical cytological abormalities without macroscopic anal lesions was 71.4% and 57.1% of patients showed positive anal capture. Prevalence of positive hybrid capture to oncogenic anal HPV in patients with cervical cytology of atypical squamous cells of undetermined significance (ASC-US) and of low grade squamous intraepithelial lesion (LSIL) was 27.1%. Prevalence in patients with cervical cytology of atypical squamous cells – cannot exclude (ASC-H), high grade squamous intraepithelial lesion (HSIL) and squamous cell carcinoma of the uterine cervix in situ or were 30%. Patients with positive cervical capture were 4 times more likely to present positive anal capture (OR=4, p=0.018). In conclusion, we found a high prevalence of anal cytology abnormalities in this population. The risk of anal contamination is significant in patients with oncogenic HPV in cervix, so all patients with abnormal cervical cytology deserve anal investigation, regardless of the severity of cytological report

Correlação entre citologia, colposcopia e histologia no diagnóstico das lesões intraepiteliais e carcinoma do colo do útero / Correlation between cytology, colposcopy and histology in diagnosing lesions of intra-epithelial and cervical carcinoma

O câncer do colo do útero é uma patologia que continua sendo um grave problema de saúde pública, sempre apresentando altas taxas de mortalidade feminina. É uma doençade progressão lenta, desenvolvendo-se a partir de transformações intraepiteliais que podem evoluir para uma lesão invasora, num período de 10 a 20 anos. No entanto, é possível sua prevenção. O diagnóstico do câncer do colo do útero é baseado na realização de três métodos complementares: a citologia, a colposcopia e a histologia. O presente estudo representa uma pesquisa quantitativa, retrospectiva e descritiva, relacionada à correlação entre citologia, colposcopia e histologia no diagnóstico das lesõesintraepiteliais e carcinoma do colo do útero, na cidade de Patos, no estado da Paraíba. Foram analisados 37 laudos de pacientes que apresentaram citologia positiva e comparadoscom a colposcopia e a histologia. A colposcopia apresentou percentual de 73% (27/37) de concordância com a citologia, e a histologia apresentou percentual de 81% (30/37). A partir da análise do presente estudo, pode-se concluir que a associação dos métodos citológicos, colposcópicos e histológicos apresenta maior eficiência do que quando utilizados isoladamente.

Normalización de un método inmunoquímico para detectar Papilomavirus humano tipo 16 en lesiones cérvico-uterinas / Standardization of immunochemical method for detection of type 16 human papilomavirus in cervix uterine lesions

Introducción: la infección por Papilomavirus Humano (PVH) es la condición necesaria para la aparición y desarrollo del cáncer cérvico-uterino. Los genotipos de alto riesgo oncogénico son los causantes de este tipo de neoplasia y dentro de ellos el más frecuente es el PVH 16, que se encuentra aproximadamente en el 60 % de los casos. Los métodos de diagnóstico comerciales resultan costosos para países con escasos recursos económicos, lo que sugiere la búsqueda de alternativas empleando protocolos sencillos y baratos. Objetivos: normalizar un método inmunoquímico para la detección del antígeno L1 de PVH tipo 16 en muestras cérvico-uterinas de pacientes con lesiones intraepiteliales escamosas y determinar la coincidencia entre el método normalizado y la Reacción en Cadena de la Polimerasa en Tiempo Real (RCP-TR), como técnica de referencia, para estimar la utilidad de dicho método en el diagnóstico de la infección por este genotipo viral. Métodos: se compararon tres procedimientos de inmunotinción (Indirecto de inmunoperoxidasa en dos pasos, Estreptavidina-Biotina y Amplificación por polímero) respecto a sensibilidad analítica, tinción inespecífica de fondo y tiempo de terminación, para la detección de la proteína L1 de PVH 16 en líneas celulares derivadas de carcinomas cervicales humanos y en muestras cérvico-uterinas utilizadas como controles. El protocolo normalizado se aplicó a muestras cérvico-uterinas de mujeres entre 30 y 59 años, 82 con lesiones intraepiteliales cervicales y 10 sin antecedentes de alteraciones citológicas, a las que además se les determinó PVH 16 mediante RCP-TR. Resultados: el procedimiento de Estreptavidina-Biotina resultó el más sensible y específico. La coincidencia entre el método inmunoquímico y la RCP-TR fue de un 98,6 por ciento, la sensibilidad fue de un 98,57 por ciento y la especificidad de un 91,67 por ciento, con valores predictivos negativo y positivo por encima del 90 por ciento. Conclusiones: se demostró la validez del método inmunoquímico como prueba confirmatoria de la infección por PVH 16. Dicho método probó ser sensible, sencillo y no requiere de una compleja infraestructura para detectar PVH 16 en muestras cervicales. Además, esta técnica permite obtener información rápidamente y evita el uso de métodos invasivos(AU)

Introduction: Human Papillomavirus (HPV) infection is the necessary condition for the occurernce and development of cervical cancer. The high oncogenic risk genotypes are the responsible for this type of neoplasia and the most frequent is HPV 16 that affects roughly 60 percent of cases. Commercial kits for HPV detection are expensive for resource-poor countries, which suggests the search for alternative throguh non-expensive simple protocoles. Objectives: to standardize an immunochemical method for the detection of HPV 16 L1 antigen in cervical samples of patients with squamous intraepithelial lesions and to determine the diagnostic coincidence between the immunochemical method and the real-time polymerase chain reaction to estimate the usefulness of this method for the detection of cervical infection with this viral genotype. Methods: three immunostaining methods (Two-Step Indirect Immunoperoxidase, Labelled Streptavidin-Biotin and Enhanced Polymer) were compared in terms of analytical sensitivity, nonspecific background staining and time of completion, for the detection of protein L1 of HPV-16 in a cell line derived from human cervical carcinoma and clinical samples from uterine cervix. The optimized protocol was applied to 82 cervical samples from women aged 30-59 years with squamous intraepithelial lesions and to 10 samples of sexually active women without previous signals of positive cytology. The presence of type 16 HPV was also detected with the aid of RT-PCR. Results: the Streptavidin-Biotin system was the most sensitive and specific. The diagnostic agreement between the immunochemical method and the real-time polymerase chain reaction reached 98.6 percent, sensitivity was 98.57 percent and specificity was 91.67 %, with positive and negative predictive values above 90 percent. Conclusions: the validity of the immunochemical method as a confirmatory test for infection by HPV-16 has been demonstrated. The normalized immunochemical method proved to be a sensitive, simple, relatively fast method to detect HPV from clinical samples of cervical cells. Furthermore, this method provides information quickly, avoiding the use of invasive methods in patients(AU)

Study of Cervical Pap Smears in a Tertiary Hospital.

Cancer of the cervix is the third most common cancer in women. In India and other developing countries cervical cancer is the leading cause of morbidity and mortality. Cancer of cervix is readily preventable, and can be diagnosed at the pre-invasive stage with adequate and repetitive cytological screening with Papanicolaou (Pap) smears. Objectives: This is a retrospective study aimed to evaluate all previously conducted cervical smears examined at a teaching tertiary hospital during a two year period. Methods: Detailed clinical data and Pap smear cytology reports were obtained and data noted in a structured proforma. All the smears were reported as per the 2001 Bethesda system. Results: A total of 560 Pap smears were examined. Maximum number of patients was in the age group of 31 – 40 years (fourth decade). There were 32 unsatisfactory or inadequate samples (5.71%). A total of 498 smears were reported as Negative for Intraepithelial Lesion or Malignancy (NILM), of which 95 (16.96%) showed normal cytological findings and 403(71.96%) were inflammatory. Out of a total of 433(77.32%) abnormal Pap smears, only 30(6.92%) cases were reported to have epithelial cell abnormality. The 30 abnormal cases comprised of 13 cases with ASC-US, 11 cases of LSIL, two cases of HSIL, three cases of invasive squamous cell carcinoma and one case of adenocarcinoma cervix. Conclusion: Premalignant and malignant lesions of cervix can be diagnosed easily by Pap smears. The epithelial cell abnormality rate in our study was 5.36%.

Persistencia o recidivas de NIC en pacientes conizadas / Persistence or recurrence of CIN in patients cone biopsy

Objetivo: Evaluar la persistencia/recidiva de lesiones pos-cono, con bisturí frío en pacientes que presentaron neoplasia cervical intraepitelial, en el período 1986-1988. Métodos: Se realizó estudio retrospectivo y descriptivo con 136 pacientes conizadas con bisturí frío, período 1986-1988, en el Servicio de Ginecología del Hospital Central de Maracay. Se utilizaron las historias médicas de cada paciente para la elaboración de una ficha de recolección de datos con las variables estudiadas, tomando la información del Departamento de Historias Médicas del Hospital. Resultados: De 136 pacientes conizadas el 88,23 % se mantuvieron sin persistencia/recidiva y la presentaron 11,76 %. Del 8,08 % que desarrollaron recidiva, 3,67 % fueron NIC II diagnosticados entre 16 meses y 5 años, 2,20 % fueron NIC III desarrollados entre 2 a 5 años y 1,47 % fueron NIC I, presentes a los 8 y 20 años. Se diagnosticó un cáncer invasivo a los 3 años (0,73 %). El 3,67 % presentó persistencias, 1,47 % con NIC II diagnosticados a los 6 y 9 meses y 1,47 % con NIC III diagnosticados a 4 y 9 meses. Un caso (0,73 %) presentó cáncer invasivo al año, por lo que es recomendable seguimiento en pacientes conizadas por un período no menor de 5 años, manejándolas cito-colpo-histológicamente.
