RESUMO

OBJECTIVE: This study aimed to evaluate whether severity changes with colposcopic lesion size, regardless of age. METHODS: This retrospective comparative study reviewed the records of 428 women with altered cytopathology reports who were directed by primary health care. Only those women with colposcopic alterations were evaluated (n=411). Histopathological analyses were restricted to patients who underwent excisional treatment (n=345). According to their age, they were grouped into the following: <21, 21-24, 25-35, and >35 years, and also, ≤24 and ≥25 years. The cytopathological, colposcopic, and histopathological findings were grouped according to severity. Lesion size was subjectively assessed from the colposcopic drawing recorded in the chart and according to the number of quadrants of the total cervical surface affected by colposcopic alterations in the transformation zone. Statistical significance was set at p<0.05. RESULTS: The evaluations suggested that the lesion size was directly related to the severity of the cytopathology, colposcopy, and histopathology reports for the age groups ≤24 or ≥25 years. We observed associations between lesion size and severity of the cytopathology (≤24 years, p=0.037) and histopathology (≥25 years, p=0.003) findings. CONCLUSION: The size of the lesion was directly related to the severity of the histopathological lesion in patients aged ≥25 years and cytopathological in patients aged ≤24 years.

RESUMO

Abstract Objective To report the prevalence of malignant transformation of vulvar lichen sclerosus (VLS) and possible risk factors. Methods This is a cohort study with data analysis from medical records of 138 patients with histological diagnosis of VLS registered at the Vulvar Pathology Outpatient Clinic of the University Hospital, between 2007 and 2017. Predominance of risk factors was performed using logistic regression analysis. The variables studied were the length of follow-up, age, regular or irregular follow up; presence of symptoms (dyspareunia, pruritus and/or vulvar burning); histology characteristics, the presence of epithelial hyperplasia; and the presence of autoimmune diseases. Results There were 138 patients included in the study, and among them five progressed to malignant transformation. The patients had a median age of 59 years and 83% were symptomatic. The most frequent symptom was itching with 72%. Autoimmune diseases were present in 11.6%, the most prevalent being thyroid disease. All five case of malignant transformation (0.6%) had an irregular follow up. The logistic regression analysis was used among the studied variables, and no statistical significance was found among them (p ≥ 0.05). The relationship between hyperplasia and the clinical outcome of malignant transformation, in which non-significant but acceptable p value close to 0.05 was observed. Conclusion The prevalence of malignant transformation in patients with VLS was 0.6%, and common factors were the lack of adherence to medical treatments and the loss of follow-up.

RESUMO

OBJECTIVES: to evaluate whether the colposcopic lesion size , age, kind of surgery, the status of the surgical margins and the expression of the p16 and Ki-67 immunomarkers are risk factors for persistence or recurrence of the lesion. METHODS: a cross-sectional, observational, retrospective study of patients submitted to cold knife conization (CKC) or the loop electrosurgical excision procedure for cervical intraepithelial neoplasia 2 or 3. The colposcopic lesion size, age, surgical method, involvement of the surgical margins, and p16/Ki-67 immunomarker expression were analyzed in relation to lesion persistence and recurrence. RESULTS: seventy-one women were treated with cold knife conization and 200 were treated with loop electrosurgical excision. Of these, 95 had cervical intraepithelial neoplasia 2, 173 had cervical intraepithelial neoplasia 3, 183 had free surgical margins, 76 had compromised margins, and 12 showed damage by processing artifact or fragments. Among the 76 cases with positive margins, 55, 11, and 10 showed endocervical margin involvement, ectocervical margin involvement, and both endocervial and ectocervical margin involvement, respectively. Of the 264 followed-up patients, 38 had persistent or recurrent disease. A multiple logistic regression indicated that positive endocervical margins are the only independent risk factor for the persistence/recurrence of cervical intraepithelial neoplasia. No significant association was identified between the colposcopic lesion size, age, surgery type, or p16/Ki-67 immunomarker expression and lesion persistence or recurrence.

RESUMO Objetivos: avaliar se o status das margens, idade, tamanho da lesão colposcópica, tipo de cirurgia e expressão dos marcadores p16/Ki-67 são fatores de risco na persistência ou recidiva da LIEAG. Métodos: um estudo de corte transversal, observacional com coleta de dados retrospectivos de pacientes submetidas a conização a frio (CF) ou exérese da zona de transformação por cirurgia de alta frequência EZT por NIC2/3. Foram analisados os seguintes fatores em relação a persistência ou recidiva: comprometimento das margens, idade, tamanho da lesão, tipo de cirurgia e coexpressão dos imunomarcadores p16 e Ki-67. Resultados: 271 mulheres tratadas com CF (71) e EZT (200), onde 95 apresentavam NIC 2 e 173 NIC 3, 183 apresentaram margens cirúrgicas livres, 76 comprometidas e 12 prejudicadas por artefatos ou fragmentação. Das 76 pacientes com margens comprometidas, 55 foram endocervical, 11 ectocervical e 10 ambas as margens. Das 264 pacientes que tiveram seguimento, 38 persistiram ou recidivaram a doença. A regressão logística múltipla indicou ser a margem endocervical comprometida o único fator independente de risco de persistência/recorrência da NIC (p<0,001). Não houve associação significativa entre a idade, o tamanho da lesão colposcópica, o tipo de cirurgia e a expressão dos imunomarcadores p16/Ki-67 e a persistência ou recorrência da doença. Conclusão: entre os fatores estudados associados com persistência ou recorrência, somente a margem endocervical comprometida provou ser significativamente um fator risco para persistência ou recorrência da lesão.

RESUMO

OBJECTIVE: To evaluate whether colposcopy-directed biopsy is necessary to increase the accuracy of diagnosing cervical intraepithelial lesions in relation to colposcopy. METHODS: We performed a retrospective, observational study by analyzing medical records obtained from Hospital de Clínicas do Paraná from February 2008 to February 2018. Patients with results of Pap tests, colposcopy, colposcopy-directed biopsy, and surgical procedures (high-frequency surgery or cold conization) were included. Data such as quadrants involved during colposcopy and age differences were also analyzed. RESULTS: A total of 299 women were included. Colposcopy was found to have an accuracy rate of 76.25% (95% confidence interval [CI], 71.4-81.1). Among the highest-grade lesions, the accuracy rate was 80.5% (95% CI, 75.7-85.3). The accuracy rates for biopsy were 79.6% (95% CI, 75-84.2) and 84.6% (95% CI, 80-89.1) for the highest-grade lesions. High-grade lesions were accurately confirmed in 76.9% and 85% of patients with 1 and 2 or more affected quadrants, respectively. For women younger than 40 years, the accuracy rates were 77.6% and 80.8% for colposcopy and biopsy, respectively. For women 40 years or older, the accuracy rates were 72.5% and 76.3% for colposcopy and biopsy, respectively. CONCLUSION: There is no difference between the accuracy of colposcopy and that of biopsy in diagnosing cervical intraepithelial lesions in relation with the result of conization. The patients who received the greatest benefit when biopsy was not performed were those with high-grade lesions at colposcopy, a lesion involving 2 or more quadrants, and those younger than 40 years.

OBJETIVO: Avaliar se a biópsia colpodirigida é necessária para aumentar a acurácia diagnóstica nas lesões intraepiteliais de colo uterino em relaçãoà colposcopia. MéTODOS: Estudo retrospectivo, observacional, incluindo pacientes submetidas a colposcopia, biópsia colpodirigida, e procedimento cirúrgico (cirurgia de alta frequência ou conização a frio), no período de fevereiro de 2008 a fevereiro de 2018, no Hospital de Clínicas da Universidade Federal do Paraná. Dados como número de quadrantes da lesão presentes na colposcopia, número de fragmentos retirados nas biópsias e diferenças por idade também foram analisados. RESULTADOS: Um total de 299 mulheres foram incluídas. Foi encontrada uma acurácia de 76,25% (intervalo de confiança [IC] 95% 71,4­81,1) entre a colposcopia e a conização, sendo 80,5% % (IC 95% 75.7­85.3) nas lesões de maior grau. A acurácia da biópsia foi de 79,6% (IC 95% 75­84,2), sendo 84,6% (IC 95% 80­89,1) nas lesões de maior grau. Pacientes com 1 quadrante acometido tiveram confirmação de 76,9% nas lesões de maior grau, enquanto as com 2 quadrantes acometidos apresentaram o mesmo resultado em 85% dos casos. A acurácia com a biópsia de 1 fragmento foi de 78% e com 2 ou mais fragmentos 80%. Para mulheres com menos de 40 anos, a acurácia foi de 77,6% e 80,8% para colposcopia e biópsia, respectivamente. Para mulheres com 40 anos ou mais, a acurácia foi de 72,5% e 76,3% para colposcopia e biópsia, respectivamente. CONCLUSãO: Não há diferença entre a acurácia da colposcopia e a da biópsia colpodirigida no diagnóstico de lesões intraepiteliais cervicais em relação ao resultado da conização. As pacientes que tiveram o maior benefício quando a biópsia não foi realizada foram as que apresentaram lesão de alto grau na colposcopia e aquelas com menos de 40 anos, não existindo benefício em realizar biópsia previamente a conização neste grupo de pacientes.

RESUMO

OBJECTIVE: To determine the accuracy of colposcopy findings in diagnosing cervical intraepithelial neoplasia (CIN) in women with an atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (ASC-H) pap smear result and analyze whether the prevalence of HSIL and cancer correlates with sociodemographic risk factors and specific colposcopic findings. METHODS: Colposcopic findings and sociodemographic risk factors were analyzed as possible predictors of a CIN 2 or worse diagnosis in women with an ASC-H pap smear result. RESULTS: Accuracy of the colposcopic impression was 92%, sensitivity was 91.6%, and specificity was 93.1%, with a positive predictive value of 96.4% and negative predictive value of 84.3%. Diagnosis of CIN 2 or worse was more frequent in patients with a previous history of cervical dysplasia and pre-menopausal patients. Identification of major colposcopic findings, dense acetowhite epithelium, coarse mosaicism, and punctuation correlated significantly with CIN 2 or worse. CONCLUSION: Colposcopy performed by an experienced examiner can accurately differentiate patients with CIN 1 or less from patients with CIN 2 or worse. Diagnosis of CIN 2 or worse was more frequent in patients with a previous history of cervical dysplasia and pre-menopausal patients. The degree of acetowhite changes was the best colposcopic feature to predict CIN2 or worse.

OBJETIVO: Determinar a acurácia dos achados colposcópicos no diagnóstico das neoplasias intraepiteliais cervicais (NIC) em mulheres com resultado de exame citopatológico de células escamosas atípicas de significado indeterminado não podendo excluir lesão intraepitelial de alto grau (ASC-H) e analisar a correlação entre a prevalência de HSIL ou câncer com fatores de risco sociodemográficos e achados colposcópicos específicos. MéTODOS:: Os achados colposcópicos, e os fatores de risco sociodemográficos foram analisados como possíveis preditores de diagnóstico NIC 2 ou mais grave em mulheres com resultado de exame citopatológico ASC-H. RESULTADOS: A acurácia da impressão colposcópica foi de 92%, sensibilidade foi 91,6%, e a especificidade foi de 93,1%, com um valor preditivo de 96,4% e valor preditivo negativo de 84,3%. O diagnóstico de NIC 2 ou mais grave foi mais frequente em pacientes com história pregressa de displasia cervical e nas que não estavam na pós menopausa. A identificação de achados colposcópicos maiores, epitélio acetobranco denso, mosaico e pontilhados grosseiros se correlacionaram positivamente com o diagnóstico NIC 2 ou mais grave. CONCLUSãO:: A colposcopia realizada por um examinador experiente pode diferenciar com acurácia pacientes com NIC 1 ou menos grave de pacientes com NIC 2 ou mais grave. O diagnóstico de NIC 2 ou mais grave foi mais frequente em pacientes com história pregressa de displasia cervical e pacientes que estavam na pré menopausa. A densidade da acetorreação foi o melhor preditor colposcópico para NIC 2 ou mais grave.

RESUMO

Introdução: O exame de Papanicolau é uma importante ferramenta na triagem do carcinoma do colo uterino. O diagnóstico citológico de atipias celulares escamosas de significado indeterminado favorecendo lesão de alto grau (ASC-H) é a categoria de menor concordância interobservador. Objetivo: Avaliar o grau de concordância interobservador para os diagnósticos de ASC-H e de lesões intraepiteliais escamosas de alto grau (LIEAG) em um hospital terciário e avaliar a capacidade do diagnóstico de ASC-H para predizer lesões de maior grau. Método: Foram coletadas lâminas de pacientes atendidas entre 2007 e 2015 no Serviço de Anatomia Patológica do hospital, com diagnósticos originais de ASC-H ou LIEAG realizados pelo mesmo patologista, colposcopia e biópsia, quando indicadas, pelo mesmo ginecologista. Essas citologias foram posteriormente revisadas por outros dois patologistas separadamente e às cegas. Ambos tiveram acesso a dados sobre idade no momento do diagnóstico para reproduzir o diagnóstico da prática clínica. Resultados: Houve 65,1% de lâminas listadas com ASC-H e 34,9% com LIEAG. As duas revisões concordaram concomitantemente com o diagnóstico original em 54,7%. Os índices kappa para os dois diagnósticos e somente para ASC-H foram, respectivamente, 0,46 e 0,49 (concordâncias moderadas). Das lâminas originalmente interpretadas como ASC-H, 68,3% resultaram em lesões de maior grau na histologia. Conclusão: Os dados mostraram uma concordância moderada entre os patologistas para o diagnóstico de ASC-H. É importante destacar que o diagnóstico de ASC-H correspondeu à lesão de maior grau de malignidade na histologia, demonstrando que essas lesões devem ser seguidas clinicamente como LIEAG

Introduction: The Papanicolaou test is an important screening exam for cervical carcinoma. The cytological diagnosis of undetermined atypical squamous cells favoring high-grade lesion (ASC-H) is the category with the least interobserver concurrence. Objective: Evaluate the interobserver concurrence for the ASC-H and high-grade squamous intraepithelial lesions (HSIL) categories at a teaching hospital and to estimate ASC-H's capacity to predict higher grade lesions. Method: Smears from patients admitted from 2007 to 2015 whose original diagnosis was made by one pathologist, in addition to colposcopy and biopsy, when indicated, made by one gynecologist were collected in the Pathologic Anatomy Service of the hospital. The cytology was reviewed by two other pathologists separately and blindly. Both reviewers had access to data about age at the moment of the diagnosis in order to reproduce the clinical diagnosis. Results: There were 65.1% smears considered as ASC-H and 34.9%, as HSIL. The reviews concurred simultaneously with the original diagnosis in 54.7% of the cases. The kappa indexes for both categories and only for ASC-H were, respectively, 0.46 and 0.49 (moderate concurrence). 68.3% of the smears primarily described as ASC-H resulted in higher grade lesions in histology. Conclusion: The data showed a moderate concurrence between the pathologists for the ASC-H's diagnosis. It is important to highlight that ASC-H matched with higher grade lesions at the histology, needing follow-up as HSIL

Introducción: La prueba de Papanicolaou es un importante examen de detección del carcinoma del cuello uterino. El diagnostico citológico de las células escamosas atípicas, no se descarta una lesión de grado alto (ASC-H) es la categoría de menor acuerdo interobservador. Objetivo: Los objetivos de este estudio fueron evaluar el grado de concordancia interobservador para los diagnósticos de atipias escamosas de significado indeterminado favoreciendo lesión de alto grado (ASC-H) y de lesiones intraepiteliales escamosas de alto grado (LIEAG) en un hospital terciario de Curitiba (PR) y evaluar la capacidad del diagnóstico de ASC-H de predecir las lesiones de mayor grado. Método: Se recogieron del Servicio de Anatomía Patológica del hospital las láminas de pacientes atendidas entre 2007 y 2015, con diagnósticos originales de ASC-H o LIEAG realizados por el mismo patólogo y colposcopia y biopsia, cuando indicadas, por el mismo ginecólogo. Esas citologías fueron revisadas después por otros dos patólogos separadamente y a ciegas. Ambos tuvieron acceso a datos sobre edad en el momento del diagnóstico para reproducir el diagnóstico de la práctica clínica. Resultados: Hubo el 65,1% de las láminas señaladas con ASC-H y el 34,9%, con LIEAG. Las revisiones concordaron concomitantemente con el diagnóstico original en el 54,7%. Los índices kappa para los dos diagnósticos y solamente para ASC-H fueron, respectivamente, 0,46 y 0,49 (concordancias moderadas). De las láminas originalmente interpretadas como ASC-H, 68,3% resultaron en lesiones de mayor grado en la histología. Conclusión: Hubo una concordancia moderada entre los patólogos para la categoría ASC-H. Se destaca también la correspondencia de ASC-H con lesiones de mayor grado en la histología, lo que dirige su seguimiento clínico como LIEAG
