Study of 138 vulvar lichen sclerosus patients and the malignant risk transformation.

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.

Is the colposcopic lesion size a predictor of high-grade lesions in young patients?

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.

Reevaluation of negative cervical conizations: Frequency, diagnostic errors, risk factors and management.

OBJECTIVE: Cervical conization is an effective treatment for precancerous lesions. However, in cases where no high-grade lesion is identified in the surgical specimen, managing these patients may be challenging due to the absence of established follow-up protocols for negative conizations. This study aimed to assess the negative conization rates at our institution by histopathological review, identify diagnostic errors, possible risk and recurrence factors and propose follow-up strategies for this group of patients. METHODS: A retrospective study from January-2010 to December-2020 analyzed patients with negative conization including all surgical techniques and procedure indications. Biopsy and cervical conizations slides were reviewed and patients who kept a negative result underwent deeper levels sectioning of the paraffin blocks with immunohistochemical stains application: p16, Ki-67 and geminin. Data were compared with a control group composed by 29 women with CIN3. RESULTS: Out of 1022 conizations, 186 were negative (18.1%), with 151 cases selected for the study after excluding 35 patients. Following pathology review, 4 patients were excluded due to false-positive cervical biopsy results, 16 for false-negative conization results and 9 for hidden dysplasia identified after deeper sectioning. The remaining 122 patients were considered truly negative cones (11.9%) and exhibited IHC staining with p16 positive in 20.4% of cases, low Ki-67 expression, and low geminin score in most cases. Specimens with CIN 1 had higher prevalence of p16 staining, Ki-67 expression and geminin score when compared to absence of neoplasia, nevertheless geminin had no statistical difference. Older age, higher parity and IHC pattern with negative p16, low Ki-67 and geminin expressions were identified as risk factors for negative cones (p<0.05). Only 10 patients recurred for high-grade lesions, with no statistically significant risk factors identified. CONCLUSIONS: The negative conization rate was 11.9%, with diagnostic errors identified across pre-surgical biopsy, cone specimen, and deeper levels. Risk factors included older age, higher parity, low expression of p16, Ki-67 and geminin (p<0.05). Recurrence represented 8.1% of the negative cones, without identification of statistically significant risk factors. Pathological review with deeper level sections and 2-year follow-up are recommended for patients with negative conizations.

Risk Factors for Persistence or Recurrence of High-Grade Cervical Squamous Intraepithelial Lesions.

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.

Diagnostic value of p16 and Ki-67 expression in cervical glandular intraepithelial disease: A review.

OBJECTIVES: Cervical adenocarcinoma has been increasing in frequency, particularly among young women. Its diagnosis still presents many challenges. In addition to the difficulty in accessing the lesion, the lack of well-established criterias for cytological and histological diagnosis, and colposcopic images that are often not very clear, there are many benign situations that mimic glandular diseases. Immunohistochemistry has been used to aid this diagnosis. The purpose of this review is to evaluate the data available in the literature related to the use of p16 and Ki-67 as an auxiliary tool in the diagnosis of glandular disease. METHODS: Original articles were searched in the PUBMED/MEDLINE, EMBASE, SCOPUS and BVS using different combinations of keywords and descriptors. RESULTS: Of the 83 initial articles, 10 were selected. The criterias used for immunohistochemical interpretation showed many differences. The studies compared benign pathologies to malignant pathologies and some used panels with different immunomarkers while others used only p16. P16 showed an intense staining pattern in malignant pathologies, despite some studies have shown a negative pattern in adenocarcinoma. This can be explained by the histological subtype, not always related to HPV. Some studies have shown immunopositivity for p16 in normal tissues, tubal metaplasia and cervical endometriosis, but the staining pattern was never intense, as in malignant tissues. Ki-67 showed a more intense staining in AIS and adenocarcinoma tissues and was also present in normal tissues, mainly in tubal metaplasia and cervical endometriosis. CONCLUSIONS: Biomarkers have proved to be important tools in aiding the diagnosis of glandular lesions, either alone or in panels. Standardization in the interpretation of immunochemistry is required.

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.

When is There no Benefit in Performing a Biopsy in the Suspicion of Intraepithelial Lesions of the Cervix?

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.

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.

EPIDEMIOLOGICAL ASSESSMENT AND EXPRESSION OF MARKERS P16/KI67 AS RISK FACTORS IN PERSISTENCE OR RECURRENCE OF HIGH GRADE SQUAMOUS INTRAEPITHELIAL LESION / AVALIAÇÃO EPIDEMIOLÓGICA E EXPRESSÃO DOS MARCADORES P16/KI67 COMO FATORES DE RISCO NA PERSISTÊNCIA OU RECIDIVA DA LESÃO INTRAEPITELIAL DE ALTO GRAU

Background: Even when pre-neoplastic lesions are treated, there is a risk that the disease will persist or recur. Objectives: Assess whether the status of the surgical margins, the age, the colposcopic lesion size,type of surgery and the expression of the P16 and KI67 markers are risk factors for the persistence or recurrence of high-grade squamous intraepithelial lesion after CIN 2 and CIN 3 treatment. Methods: A cross-sectional, observational study with retrospective data collection of patients undergoing cold knife( CKC) or Loop electrosurgical excision procedure (LEEP) for CIN 2 or CIN 3. The following factors were analyzed in relation to recurrence: compromised margins, age, lesion size, type of surgery and staining of immunomarkers P16 and KI67. Results: Among the 271 women, aged between 17 and 67 years, 71 had CKC and 200 LEEP, 95 had CIN 2 and 173 CIN 3, regarding the status of the margins, 183 patients had free surgical margins, 76 compromised and 12 damaged by artifacts or fragmentation. Of the 76 with compromised margins, 55 were endocervical, 11 ectocervical and 10 both margins. Of the 264 who completed followup, 38 persisted or relapsed the disease. A hundred-five reactions with the P16 marker were performed. As for the analysis of the P16 color intensity, 8 cases were mild, 32 moderate and 65 were strong. Regarding the analysis of immunostained epithelial thickness, 7 had 1/3 of the epithelium stained, 36 stained 2/3 and 62 stained the entire epithelium. A total of 113 reactions with the 67 KI marker were performed. As for the analysis of staining intensity, 3 cases were mild, 24 moderate and 86 strong. Regarding the analysis of immunostained epithelial thickness, 6 occurred in 1/3 of the epithelium, 48 in 2/3 and 59 in the entire epithelium. Conclusion: Only the status of the endocervical margins was associated with the persistence or recurrence of the lesion. Age, colposcopic lesion size, type of surgery and expression of P16/KI67 markers were not associated with recurrence or persistence of the lesion.

Reliability of negative cone specimens of the cervix: A review.

OBJECTIVES: Cervical conization specimens with a negative result for high-grade lesion are not infrequent in clinical practice and there are no protocols to address this issue. The purpose of this manuscript is to analyze factors that affect the reliability on these situations and provide recommendations to guide the gynecologists on their practice. METHODS: We searched original articles on Pubmed/Medline database that analyzed negative cones using different combinations of descriptors. There were no restrictions regarding the language or the year of publication. RESULTS: Nineteen articles were selected and a total of 7310 cones analyzed. The negative excision rate ranged from 10 to 35%. Among the reasons to explain absence of lesion, the most frequent were errors in colposcopy, spontaneous lesion regression, complete removal of small lesions during biopsy, errors in the pre-conization material, false-negative results, and excisional error. Pathological specimen review and application of immunohistochemical biomarkers p16 and Ki-67 seemed to improve accuracy and help in challenging differential diagnosis. Recurrence was detected in up to 30%, as seen in positive cones with compromised margins. Importantly, testing for HPV demonstrated benefits in reducing the number of negative cones. CONCLUSIONS: Several factors could contribute to a negative result in a conization. Our main recommendations include: interval of 4-6 weeks between biopsy and conization, repeat the colposcopy during the excision, consider short-term reevaluation for small colposcopy lesions, perform deep sectioning levels in the paraffin block, use of immunohistochemical markers, HPV testing, and strict surveillance during follow-up as performed for positive cases with compromised margins.

Colposcopic Findings and Diagnosis in Low-Income Brazilian Women with ASC-H pap Smear Results.

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.

Concordância Interobservador no Diagnóstico Citológico de Atipia Escamosa de Significado Indeterminado Favorecendo Lesão de Alto Grau e de Lesão / Intraepitelial Escamosa de Alto Grau nas Lesões do Colo Uterino Interobserver Agreement in Cytological Diagnosis of Atypical Squamous Cell, Cannot Exclude a High-Grade Lesion and High-Grade Squamous Intraepithelial Lesion in Cervical Lesions / Concordancia Interobservador en el Diagnóstico Citológico de Atipia Escamosa de Significado Indeterminado Favoreciendo Lesión de Alto Grado y Lesión Intraepitelial Escamosa de Alto Grado en Lesiones del Cuello Uterino

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

Opções terapêuticas na neoplasia intraepitelial vaginal: revisão de literatura / Therapeutic modalities for vaginal intraepitelial neoplasia: literature review

A neoplasia intraepitelial de vagina (NIVA) é uma condição pré-maligna rara do epitélio vaginal, sua incidência corresponde a 0,2 casos por 100.000 mulheres, classifica-se em NIVA I, II, III esta última tem um potencial de invasão de 9 a 12%. O diagnóstico é feito pela citologia, colposcopia, histopatologia. Todos os métodos terapêuticos tem uma taxa razoável de sucesso e a taxa de recorrência varia entre 10 e 42%. O tratamento pode ser: cirúrgico, ablativo, radioterápico, clínico e expectante. O excisional tem preferência por fornecer peça para análise histopatológica excluindo a doença invasiva apresentando as melhores taxas de sucesso entre 66% a 83% . A ablação é indicada quando a suspeita de invasão foi afastada e é a modalidade de eleição nas mulheres jovens, a eficácia varia entre 69 a 87%. A radiação tem uma taxa de sucesso entre 69 a 100%; porém, as complicações giram em torno de 36%. Pela sua praticidade o tratamento feito com os agentes tópicos tem ganhado espaço terapêutico na abordagem da NIVA. Não existe evidência científica quanto a melhor forma e o tempo de seguimento das mulheres com NIVA. Qualquer que seja a opção de tratamento utilizada um seguimento longo deve ser preconizado.(AU)

Vaginal intraepithelial neoplasia (VAIN) is an uncommon premalignant condition of the vaginal epithelium, its incidence is found to be 0.2 per 100.000 women, this condition is classificated in VAIN I, II and III, the lifetime risk of transformation to invasive carcinoma has been reported as 9 to 12%. The diagnosis was done by cytology, colposcopy and histology. All the therapeutics modalities have a successful cure rate and the recurrence ranges are between 10 to 42%. The treatment modalities are: excisional, ablative, radiotherapic, clinical and expectante. Excisional has preference as it could exclude invasion disease and has the best success rate, 66 to 83%. Ablation has preference in young women with no suspect of invasion, with efficacy ranging between 69 to 87%. The cure rate of radiotherapy is high as 69 to 100% but this modality has 36% morbidity rate. Treatment with topical agents constitutes a promising option in VAIN management. There is no scientific evidence of what kind follow-up is better. Whatever treatment modality is used long-term follow-up is essential.(AU)

A regeneração do colo uterino após tratamentos excisionais das neoplasias intraepiteliais cervicais: repercussões futuras / Uterine cervix regeneration after excisional treatmentfor cervical intraepithelial neoplasia: future implications

Os tratamentos excisionais para as neoplasias intraepiteliais cervicais podem ter como consequência o trabalho de parto prematuro e a colposcopia inadequada em decorrência da estenose do canal cervical, além da possibilidade de comprometimento da resposta imune aferente contra novas lesões. Algumas escolhas feitas pelo cirurgião podem otimizar o processo cicatricial e minimizar esses efeitos. São elas: evitar o tratamento desnecessário das lesões, as cauterizações profundas e as suturas em demasia, bem como orientar a paciente sobre o período de tempo que deverá ser aguardado antes de uma possível gestação.(AU)

Excisional treatments for cervical intraepithelial neoplasia may result in preterm labor and inadequate colposcopy, as a consequence of cervical canal stenosis, in addition to the possibility of reducing the afferent immunologic response against new lesions. Some choices made by the surgeon can optimize the healing process and minimize these effects, such as: avoiding unnecessary treatment of the lesions, deep cauterizations and excessive sutures, as well as advising the patient about the proper time to wait before a possible pregnancy.(AU)

Number of fragments, margin status and thermal artifacts of conized specimens from LLETZ surgery to treat cervical intraepithelial neoplasia.

CONTEXT AND OBJECTIVE: Large loop excision of the transformation zone (LLETZ) is a nontraumatic cut and coagulation method with several advantages, but it induces thermal artifacts in the cut region. The aim here was to assess the correlations of age, number of fragments, lesion grade and degree of thermal artifacts with margin quality in conized specimens from LLETZ for cervical intraepithelial neoplasia (CIN). DESIGN AND SETTING: Cross-sectional study at Universidade Federal de São Paulo (Unifesp). METHODS: The records and histopathology findings of 118 women who underwent LLETZ between 1999 and 2007 were reviewed. Age, number of fragments, lesion grade, degree of thermal artifacts and margin quality were assessed. RESULTS: The patients' mean age was 27.14 years; 63.6% had been diagnosed with CIN II and 36.4% with CIN III. The lesion was removed as a single fragment in 79.6% of the cases. The margins were free from intraepithelial neoplasia in 85.6% and compromised in the endocervical margin in 6.8%. Fragment damage due to artifacts occurred in 2.5%. Severe artifacts occurred in 22.8%. Women aged 30 years or over presented more cases of CIN III (P < 0.0004). Neoplastic compromising of surgical margins and severe artifacts occurred more often in cases in which two or more fragments were removed, and in patients aged 30 years or over. CONCLUSION: CIN III in women aged 30 or over, when removed in two or more fragments during LLETZ, presented a greater number of compromised margins and greater severity of thermal artifacts.
