Tumor de colisión de útero. Reporte de caso y revisión de la literatura / Uterine collision tumor. Case report and review of he literature

Objetivos: Reportar el caso de una paciente con tumor de colisión del útero y realizar una revisión de la literatura respecto al diagnóstico histopatológico, tratamiento y pronóstico de esta condición. Materiales y métodos: Mujer de 76 años que consultó al centro nacional de referencia del cáncer en Bogotá (Colombia), donde se hizo el diagnóstico de tumor de colisión del útero, compuesto por un adenocarcinoma de endometrio tipo seroso y adenosarcoma de cérvix. Recibió tratamiento quirúrgico más quimioterapia y radioterapia complementaria, falleció a los 16 meses. Se realizó una búsqueda de la literatura en las bases de datos Medline vía PubMed y Embase, que incluía reportes y series de caso de mujeres con diagnóstico de tumor de colisión del útero, y se extrajo información sobre el diagnóstico, tratamiento y pronóstico. Se realizó un resumen narrativo de los hallazgos. Resultados: La búsqueda identificó 36 títulos, de los cuales se incluyeron 14 estudios que incluían 17 pacientes. El diagnóstico histopatológico más frecuente fue el adenocarcinoma endometrioide de endometrio y sarcoma endometrial de alto y bajo grado (47 %). El tratamiento básico fue quirúrgico. Cerca del 50 % recibió tratamiento adyuvante con quimioterapia y radioterapia (15 %). La sobrevida a un año fue del 75 %. Conclusiones: En la literatura no se identificaron casos de tumores de colisión de útero con la histopatología y en la ubicación del caso presentado. La mortalidad a dos años es cercana al 28 % si se toma en cuenta el caso reportado. Se necesitan más estudios que describan la inmunohistoquímica, el tratamiento y el pronóstico de esta condición.

Objectives: To report the case of a patient with a uterine collision tumor and to conduct a review of the literature. Material and methods: A 76-year-old patient who presented to the national cancer referral center in Bogota (Colombia), where she was diagnosed with a uterine collision tumor consisting of a serous-type endometrial adenocarcinoma and a cervical adenosarcoma. The patient underwent surgical treatment followed by chemotherapy and supplemental radiotherapy, and died 16 months later. A search was conducted in the Medline via PubMed and Embase databases, including reports and case series of women with a diagnosis of uterine collision tumor, with retrieval of information regarding diagnosis, treatment and prognosis. A narrative summary of the findings was made. Results: The search identified 36 titles, of which 14 studies with 17 patients were included. The most frequent histopathological diagnosis was endometrial adenocarcinoma and high and low grade endometrial sarcoma (47 %). Primary treatment was surgery and adjuvant treatment with chemotherapy and radiotherapy (15 %) was performed in close to 50 % of cases. One-year survival was 75 %. Conclusions: No cases of uterine collision tumors with the histopathology or in the location of the reported case were found in the literature. If this reported case is taken into account, 2-year mortality is 28 %. Further studies to describe the immunohistochemistry, treatment and prognosis of this condition are needed.

Tamización primaria con prueba ADN-VPH en mujeres menores de 30 años: evaluación de tecnología sanitaria / Primary HPV-DNA screening in women under 30 years of age: health technology assessment

Antecedentes A partir del 2014 en Colombia se incorporó la Tamización primaria con prueba de Virus del Papiloma Humano (VPH) desde los 30 hasta los 65 años, cuando la prueba es positiva se hace triage con citología para remisión a colposcopia. Actualmente se discute la conveniencia de iniciar la tamización con prueba de ADN de VPH a partir de los 25 años. De esta manera, el objetivo de esta evaluación de tecnologías sanitarias es analizar la evidencia disponible en torno a la seguridad, efectividad, costoefectividad, valores y preferencias, dilemas éticos y aspectos relacionados con la implementación para el contexto colombiano de la prueba ADN-VPH como estrategia de tamización cervical en mujeres menores de 30 años. Dominios a evaluar Eficacia clínica y seguridad 1. Tasa acumulada de neoplasia intraepitelial cervical (NIC) grado 2 o más avanzado luego de 2 rondas de tamización. 2. Tasas acumuladas de cáncer invasor de cérvix luego de 2 rondas de tamización. 3. Seguridad: remisión a colposcopia. Costo-efectividad Costo efectividad para Colombia. Otros dominios considerados Aspectos éticos asociados a la tamización cervical en mujeres menores de 30 años. Aspectos organizacionales y del individuo. Barreras y facilitadores relacionados con la implementación en el contexto colombiano de la tamización cervical en mujeres menores de 30 años. Métodos Evaluación de efectividad y seguridad clínicas Se realizó una búsqueda sistemática de la literatura en MEDLINE, Embase y CENTRAL de revisiones sistemáticas y ensayos clínicos. Se calificó el cuerpo de la evidencia con la aproximación GRADE. Posteriormente, se convocó a un grupo interdisciplinario a una mesa de trabajo en donde se presentó la evidencia recuperada, dando paso a la discusión y a la construcción de las conclusiones, siguiendo los lineamientos de un consenso formal acorde a la metodología RAND/UCLA. Estudio económico Se hizo una búsqueda sistemática de la literatura de estudios que hubieran evaluado el costo-efectividad para Colombia. Resultados De 7.659 referencias recuperadas se incluyeron 8 estudios. Resultados clínicos Se realizó un análisis integrativo de 5 ensayos clínicos aleatorizados que cumplieron con los citerios de inclusión. Cuando se compara frente a la citología, la tamización primaria con ADN-VPH en mujeres menores de 30 años, podría asociarse con una mayor frecuencia de detección de lesiones NIC2+ durante la primera ronda de cribado (RR: 1.57; IC: 1,20 a 2,04; certeza en la evidencia baja), con una menor incidencia de NIC2+ (RR:0,67; IC: 0,48 a 0,92; certeza en la evidencia baja) y se asocia con una menor frecuencia de carcinoma invasor al término del seguimiento (RR: 0,19; IC: 0,07 a 0,53; certeza en la evidencia alta). Resultados económicos Desde el punto de vista económico, la alternativa de ADN-VPH y triage con citología desde los 25 años quizás representa la alternativa más costo-efectiva para Colombia (razón costo-efectividad incremental $8.820.980 COP año 2013). Otras implicaciones Dos estudios sugieren que las barreras de implementación, atribuibles a circunstancias de intermediación, de orden público y de carácter geográfico, podrían ser solventadas por nuevas tecnologías o estrategias de cribado. Es importante considerar alternativas de forma de administración y de prestación de servicios para solventar algunas barreras de aceptabilidad y acceso. Todo programa de tamización cervical debe contemplar los principios éticos de no maleficencia, beneficencia, autonomía y equidad. Futuros estudios deben enfocarse en analizar nuevas tecnologías de cribado con énfasis en población menor de 30 años. Conclusiones El uso de la prueba ADN-VPH como estrategia de tamización en mujeres menores de 30 años es una intervención probablemente efectiva y costoefectiva para Colombia. Futuros estudios deben enfocarse en analizar nuevas tecnologías de cribado con énfasis en población menor de 30 años.

Background Primary screening with Human Papilloma Virus (HPV) testing was introduced in Colombia in 2014 for individuals between 30 and 65 years of age. When the result is positive, cytology triage is performed for colposcopy referral. The convenience of initiating HPV-DNA testing for screening at 25 years of age is currently a subject of discussion. Therefore, the objective of this health technology assessment (HTA) is to analyze the available evidence regarding safety, efficacy, cost-effectiveness, values and preferences, ethical dilemmas and considerations pertaining to the implementation of the HPV-DNA test as a cervical screening strategy in women under 30 years of age in the Colombian context. Domains to be assessed Clinical efficacy and safety 1. Cumulative rate of cervical intraepithelial neoplasia (CIN) grade 2 or high-er after 2 screening rounds. 2. Cumulative rates of invasive cancer of the uterine cervix after 2 screening rounds. 3. Safety: referral to colposcopy Cost-effectiveness Cost-effectiveness for Colombia. Other domains considered Ethical considerations associated with cervical screening in women under 30 years of age. Organizational and individual considerations. Barriers and facilitators pertaining to the implementation of cervical screening in women under 30 years of age in the Colombian context. Methods Clinical efficacy and safety assessment A systematic literature search of systematic reviews and clinical trials was conducted in MEDLINE, Embase and CENTRAL. The body of evidence was rated using the GRADE approach. An interdisciplinary team was then convened to create a working group to review the retrieved evidence. This led to the discussion and construction of the conclusions following the guidelines of a formal consensus in accordance with the RAND/UCLA methodology. Economic study Systematic literature research of studies that had assessed cost-effectiveness for Colombia. Results Out of the 7,659 references retrieved, 8 studies were included. Clinical outcomes An integrative analysis of 5 randomized clinical trials that met the inclusion critera was performed. Compared with cytology, primary HPV-DNA testing in women under 30 years of age could be associated with a lower frequency of CIN+2 lesions during the first screening round (RR: 1.57; CI: 1.20 to 2.04; low evidence certainty), and a lower incidence of CIN+2 (RR: 0.67; CI: 0.48 to 0.92; low evidence certainty). Moreover, it is associated with a lower frequency of invasive carcinoma at the end of follow-up (RR: 0.19; CI: 0.07 to 0.53; high evidence certainty). Economic results From the financial point of view, the use of HPVDNA testing plus cytology-based triage starting at 25 years of age is perhaps the most cost-effective option for Colombia (incremental cost-effectiveness ratio, COP 8,820,980 in 2013). Other implications Two studies suggest that barriers to implementation attributable to intermediation, public unrest and geographic considerations could be overcome with the use of new screening technologies or strategies. It is important to consider administration and service provision alternatives in order to overcome some acceptability and access barriers. Any cervical screening program must take into consideration ethical principles of nonmaleficence, beneficence, autonomy and equity. Future studies should focus on analyzing new screening techniques with emphasis on the population under 30 years of age. Conclusions The use of HPV-DNA testing as a screening strategy in women under 30 years of age is a potentially efficacious and cost-effective intervention for Colombia. Future studies should focus on analyzing new screening technologies, with emphasis on the population under 30 years of age.

Prevalência de alterações de exame citopatológico e sua relação com lesões compatíveis com a infecção pelo Papiloma Vírus Humano e as neoplasias do colo uterino / Prevalence of changes on cytopathological exams and their relationship with injuries compatible with human papilloma virus infection and uterine cervical neoplasms

Introdução: O objetivo deste estudo é identificar a frequência de exames citológicos de colo uterino alterados e sua relação com a infecção pelo Papiloma Vírus Humano (HPV) e neoplasias. Métodos: Foram estudadas mulheres residentes em zona urbana, que fizeram exame citopatológico entre 2015 e 2017, com registros no Sistema de Informações do Câncer. Resultados: Foram realizados 25.323 exames citopatológicos, reunindo 815 alterações (3,2%). A faixa etária mais acometida foi entre 30-40 anos. A principal alteração encontrada foi "ASC-US" (431 casos ­ 52,8%). A Lesão Intraepitelial de Baixo Grau, que compreende o efeito citopático pelo HPV e neoplasia intraepitelial cervical Grau I, foi encontrada em 164 casos (20,1%). Após exame de colposcopia, 181 pacientes realizaram biópsia, sendo mais prevalente "NIC I com Alterações Compatíveis com Ação pelo HPV" (21,5%). Conclusão: Elevada prevalência de alterações que podem evoluir para neoplasias de colo uterino, com ênfase naquelas sugestivas da presença de HPV em pacientes abaixo de 25 anos.

Introduction: This study aimed to identify the frequency of changes on cervix cytopathological exams and its relationship with Human Papilloma Virus (HPV) infection and neoplasms. Methods: Women living in the urban area who underwent cytopathological examination from 2015 to 2017 were assessed, based on records from the Cancer Information System. Results: A total of 25,323 cytopathological exams were performed, reporting 815 changes (3.2%). The most affected age group was from 30 to 40 years. The most frequent change was "ASC-US" (431 cases ­ 52.8%). Low-grade intraepithelial lesion, which encompasses the cytopathic effect of HPV and cervical intraepithelial neoplasm grade I, was found in 164 cases (20.1%). After being examined by colposcopy, 181 patients underwent biopsy, whose most prevalent finding was "grade I CIN with Changes Compatible With HPV Action" (21.5%). Conclusion: There was a high prevalence of changes that can evolve to uterine cervical neoplasms, with emphasis on those suggestive of presence of HPV in patients younger than 25 years.

Cytopathologic evaluation of patients submitted to radiotherapy for uterine cervix cancer / Avaliação citopatológica no seguimento de pacientes submetidas à radioterapia por câncer de colo uterino

Summary Cervical cancer is an important public health problem. Pap smear is the leading strategy of screening programs for cervical cancer worldwide. However, delayed diagnosis leads to more aggressive and less effective treatments. Patients with uterine cervix malignancies who are referred for radiotherapy have advanced-stage disease, which results in high rates of locoregional recurrence. The use of radiotherapy as a treatment for cervical cancer causes morphological changes in neoplastic and non-neoplastic epithelial cells, as well as in stromal cells, which make it difficult to diagnose the residual lesion, resulting in a dilemma in cytopathological routine. Based on the difficulties of cytopathologic evaluation for the follow-up of patients treated with radiotherapy for cervical cancer, our objective was to describe the actinic cytopathic effects. Our paper was based on a structured review including the period from June 2015 to April 2016, aiming at an exploratory-descriptive study. Bibliographic investigations were carried out through selection and analysis of articles, list of authors and keywords, selection of new articles focused on the analysis of bibliographic references to previously selected documents, as well as textbooks of recognized merit. The most incident actinic cytopathological alterations as described in the literature are: cellular gigantism, nuclear and cytoplasmic vacuolization, dyskeratosis, bi- and multinucleated (B/M) cells, macro and multiple nucleoli, anisokaryosis, anisonucleolosis and nuclear pyknosis. To date, a protocol has not been established that can precisely differentiate the morphological characteristics between benign cells with actinic effects from recurrent malignant cells on post-radiotherapy smears.

Resumo O câncer de colo uterino configura-se como um importante problema de saúde pública. O teste citopatológico é a principal estratégia de programas de rastreamento dessa neoplasia maligna em todo o mundo. Entretanto, a demora no diagnóstico ocasiona tratamentos mais agressivos e menos efetivos. Pacientes com neoplasia maligna de colo uterino que são encaminhadas para radioterapia apresentam doença em estádios avançados, e esse fato determina altos índices de recidiva locorregional. A utilização da radioterapia como tratamento do câncer do colo uterino provoca alterações morfológicas não só nas células epiteliais neoplásicas e não neoplásicas como também nas células estromais, o que dificulta o diagnóstico da lesão residual e resulta em um dilema na rotina citopatológica. Com base nas dificuldades da avaliação citopatológica do seguimento das pacientes pós-radioterapia, o objetivo deste trabalho foi descrever os efeitos citopáticos actínicos. O trabalho teve como base uma revisão estruturada no período de junho de 2015 a abril de 2016, visando a um estudo exploratório-descritivo. As investigações bibliográficas foram realizadas por meio de seleção e análise dos artigos, lista de autores e palavras-chave; seleção de novos artigos focada na análise de referências bibliográficas dos documentos previamente selecionados e livros-texto de relevância conceitual. As alterações citopatológicas actínicas mais incidentes descritas na literatura são: gigantismo celular, vacuolização nuclear e citoplasmática, disceratose, bi e multinucleações, macro e múltiplos nucléolos, anisocariose, anisonucleolose e picnose nuclear. Até o momento, não se conseguiu estabelecer um protocolo que possa diferenciar precisamente as características morfológicas entre células benignas com efeitos actínicos das células malignas recidivantes em esfregaços pós-radioterapia.

The utility of ADC in diagnosis of neuroendocrine carcinoma of the uterine cervix / 实用放射学杂志

Objective To assess the value of diffusion weighted imaging (DWI) and apparent diffusion coefficient (ADC) in differential diagnosis of neuroendocrine carcinoma of the uterine cervix (NECUC) from other tumors.Methods A total of 12 NECUCs,39 cervical squamous cell carcinomas (SCC) and 21 cervical adenocarcinomas (CA) confirmed by pathology were analyzed retrospectively.All the patients underwent conventional MRI and DWI.The ADC values were measured and compared among NECUC,SCC and CA.Diagnostic performance of ADC was compared using receiver operating characteristic curves (ROC).Results The mean ADC values of NECUC,SCC and CA were (0.66 ± 0.11) ×10-3 mm2/s,(0.86 ± 0.11) × 10-3 mm2/s and (1.04 ± 0.17) × 10-3 mm2 / s,with statistical differences between any two groups (P ＜0.001).The optimal cutoff values of ADC for differentiating NECUC and SCC was 0.681 ×10-3mm2/s with a sensitivity of 94.9％,specificity of 75.0％ and accuracy of 90.2％.The optimal cutoff values of ADC for differentiating NECUC and CA was 0.824× 10-3mm2/s with a sensitivity of 95.2％,specificity of 91.7％ and accuracy of 98.9％.Conclusion The differences of the mean ADC value are helpful for the differential diagnosis of NECUC,SCC and CA.

Diagnostic value of quantitative parameters of dynamic contrast-enhanced MRI in the evaluation of different pathological grades of cervical squamous cell carcinoma / 中华放射学杂志

Objective To investigate the value of dynamic contrast-enhanced MRI parameters in the diagnosis of cervical squamous cell carcinoma. Methods A retrospective analysis of dynamic contrast enhanced MRI in 55 patients with pathologically diagnosed cervical squamous cell carcinoma without prior treatment. They were divided into three groups based on grade of differentiation: well differentiated ( 6 patients),moderately differentiated(28 patients)and poorly differentiated group(21 patients). Capacity volume transfer constant (Ktrans),exchange rate constant(Kep) and extravascular extracellular volume fraction (Ve) were measured in each group of patients, and comparing the correlation with ANOVA, DCE-MRI parameters and grading of squamous differentiation using Spearman rank correlation analysis. Results Ktrans of the poorly, moderately and well differentiated cervical squamous cell carcinoma were (2.42±0.58),(1.71± 0.78),(1.27±0.78)/min respectively, Kep were (4.17±1.23),(3.08±1.58),(2.55±0.87)/min respectively, Ve were 0.60 ± 0.12,0.60 ± 0.19,0.43 ± 0.17 respectively. Statistical difference of Ktransand Kep were found among the subgroups of different pathological grading.(F values were 7.518 and 4.234,P all0.05). Statistical difference of Ktransand Kep were seen in multiple comparisons, between the groups of poorly and moderately differentiated groups poorly and well differentiated groups (P all 0.05). There were moderate negative correlation between Ktrans,Kep and the pathological degree (r=-0.531 and -0.446, P=0.001 and 0.002), Ve had no correlation between pathological grade (r= -0.220, P = 0.141).Conclusion DCE-MRI parameters Ktrans and Kep reveal perfusion characteristics in different pathological grades of cervical squamous cell carcinoma.

A Case of Metastatic Adenocarcinoma of the Pleura from the Exocervix without Local Recurrence / 대한내과학회지

It is very rare for an exocervical adenocarcinoma to metastasize to the lung parenchyma and pleura. A 54-year-old woman was admitted with dyspnea and left pleural effusion on chest X-ray. She had a history of exocervical adenocarcinoma 3 years previously and was treated with hysterectomy, chemotherapy, and radiation therapy. Last year, she was diagnosed with a left vestibular schwannoma and underwent subtotal mass removal surgery. After admission, metastatic adenocarcinoma of the pleura was diagnosed by video-assisted thoracic surgery biopsy. We herein report the rare case of exocervical adenocarcinoma that presented as a metastatic lesion to the pleura 3 years after the initial diagnosis.

O diagnóstico citológico de células escamosas atípicas: uma avaliação crítica das recomendações diagnósticas: [revisão] / Cytological diagnosis of atypical squamous cells: a critical evaluation of diagnostic guidelines: [revision]

OBJETIVO: identificar recomendações válidas para abordagem de mulheres com diagnóstico citopatológico de atipias de significado indeterminado em células escamosas (ASC), discutindo sua aplicabilidade ao cenário brasileiro. MÉTODOS: foi realizada uma busca eletrônica de publicações no PubMed, National Guidelines Clearinghouse e Google Acadêmico, além de busca manual das referências dos documentos encontrados. As diretrizes identificadas e especificamente relacionadas ao tema foram avaliadas segundo sua validade e suas recomendações, criticadas e sumarizadas. RESULTADOS: as diretrizes consideradas válidas foram aquelas elaboradas para o Reino Unido, França, Austrália, EUA e Nova Zelândia. Esses documentos recomendam que a citologia seja repetida seis ou doze meses antes de encaminhar para colposcopia nas ASC de significado indeterminado (ASC-US) e encaminhamento imediato para colposcopia em ASC nas quais não é possível afastar lesão de alto grau (ASC-H). Também foram encontradas recomendações válidas de colposcopia para mulheres com ASC-US em situações especiais (imunocomprometidas e que demandem asseguramento por especialista) e uso de testes para HPV oncogênico que, quando presente em mulheres com mais de 20 anos, deve motivar encaminhamento para colposcopia. CONCLUSÕES: as condutas clínicas preconizadas para o Programa Nacional de Controle do Câncer do Colo do Útero no Brasil podem ser aperfeiçoadas, acrescentando-se o encaminhamento para colposcopia em situações especiais (imunocomprometidas e que demandem asseguramento por especialista), o uso do teste para detecção de HPV oncogênico em mulheres com mais de 20 anos (quando presente, deve-se encaminhar para colposcopia), a investigação de lesões vaginais e o uso de preparo estrogênico prévio à colposcopia em mulheres na pós-menopausa, dispensando a biópsia quando presentes alterações menores.

PURPOSE: to identify valid guidelines for the approach of women with cytopathological diagnosis of undetermined significance atypias in squamous cells (ASC), discussing its applicability to the Brazilian scenario. METHODS: an electronic search of publications at PubMed, National Guidelines Clearinghouse and Scholar Google was carried out, as well as a manual search of references from the texts found. The guidelines identified, and specifically related to the theme, were evaluated according to its validity and the recommendations were criticized and summarized. RESULTS: guidelines for the United Kingdom, France, Australia, the USA and New Zealand have been considered as valid. These documents recommend repeating the cytology in six or twelve months, in ASCs of undetermined significance (ASC-US) before referring to colposcopy, and immediate referral to colposcopy in ASCs, when it is not possible to disregard high degree lesions (ASC-H). We have also found valid colposcopy recommendations for women with ASC-US in special situations (immune deficient women requiring specialist assistance) and the use of oncogenic HPV test, which, when present in women over 20, should motivate referral to colposcopy. CONCLUSIONS: the clinical guidelines recommended for the Programa Nacional de Controle do Cancer do Colo do Útero in Brazil can be improved with the referral to colposcopy in special situations (immune deficient women requiring specialist assistance), the use of test for the detection of oncogenic HPV in women over 20 (when present, refer to colposcopy), the investigation of vaginal lesions, the use of estrogens before the colposcopy in post-menopausal women, and disregard biopsia in case of slighter alterations.
