As células glandulares atípicas representam 0,2% a 2,1% dos resultados dos testes de Papanicolaou. Mesmo com essa baixa prevalência, tem um significado importante no diagnóstico do câncer cervical e endometrial, tendo em vista que tais células e subcategorias, associadas à idade da paciente, podem prenunciar um número expressivo de doença intraepitelial, doença invasiva do endocérvix, endométrio e até neoplasias anexiais. E não se pode esquecer do importante número de resultados histológicos benignos, identificados no seguimento dessas pacientes, muitas vezes assintomáticas.(AU)

Atypical glandular cells represent 0,2% to 2,1% of Pap test results even with this low prevalence has an important significance in the diagnosis of cervical and endometrial cancer, considering that such cells and subcategories associated with the patient's age can predict a significant number of intraepithelial disease, invasive disease of the endometrium, endocervix and even adnexial neoplasms; no forgetting the important number of benign histological results, identified in the follow up of these patients, often asymptomatic.(AU)

Abstract Introduction Malignant mesonephric tumors are uncommon in the female genital tract, and they are usually located where embryonic remnants of Wolffian ducts are detected, such as the uterine cervix. The information about these tumors, their treatment protocol, and prognosis are scarce. Case report A 60-year-old woman with postmenopausal vaginal bleeding was initially diagnosed with endometrial carcinoma. After suspicion co-testing, the patient underwent a loop electrosurgical excision of the cervix and was eventually diagnosed with mesonephric adenocarcinoma. She was subjected to a radical hysterectomy, which revealed International Federation of Gynecology and Obstetrics (FIGO) IB1 stage, and adjuvant radiotherapy. The follow-up showed no evidence of recurrence after 60 months. Conclusion We present the case of a woman with cervical mesonephric adenocarcinoma. When compared with the literature, this case had the longest clinical follow-up without evidence of recurrence, which reinforces the concept that these tumors are associated with a favorable prognosis if managed according to the guidelines defined for the treatment of patients with cervical adenocarcinomas. Though a rare entity, it should be kept in mind as a differential diagnosis for other cervical cancers.

Abstract Objective To evaluate the performance of the hybrid capture 2 (HC2) high-risk papillomavirus (hrHPV) assay and cytological test in women with previous abnormalities, to detect cervical intraepithelial neoplasia grade 2 or worse (≥ CIN 2). Methods A cytological test and HC2 (Qiagen, Gaithersburg, Maryland, EUA) for hrHPV were conducted in 359 liquid-based (Sure Path, Becton Dickinson, TriPath Imaging, Burlington, NC, USA) samples collected from women from the Vale do Ribeira Region, during July 2013 and September 2015 with previous cytology classified as atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL), atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesions (ASC-H), and atypical glandular cells (AGC). The histopathological examination was conducted in 179 women. The performance evaluations were calculated using the "exact" Clopper-Pearson 95% confidence interval (CI) test by MEDCALC (Medcalc Software Ltd, Ostend, Belgium). Results The ≥ CIN 2 frequency was 11.7% (21/179). The HC2 for hrHPV and repeat cytology to detect ≥ CIN 2 obtained, respectively, a sensitivity of 90.5% (95% CI = 69.6-98.8) and 90.5%, (95%CI = 69.6-98.8), a specificity of 65.8% (95% CI = 57.9-73.2) and 43.7% (95%CI = 35.8-51.8), a positive predictive value of 26.0% (95% CI = 21.4-31.3) and 17.6%, (95%CI = 14.9-20.6), and a negative predictive value of 98.1% (95%CI = 93.3-99.5) and 97.2% (95% CI = 90.1-99.2). Conclusion Hybrid capture 2 for hrHPV improves the performance of the detection of ≥ CIN 2, without compromising sensitivity, and provides a greater safety margin to return to the triennial screening of women undergoing follow-up due to previous abnormalities, without underlying ≥ CIN 2.

Resumo Objetivo Avaliar o desempenho da captura híbrida 2 (CH2) para papilomavírus humano de alto risco (HPVar) e repetição do exame citopatológico em mulheres com anormalidades em citologia anterior, para detectar neoplasia intraepitelial cervical grau 2 ou pior (≥ NIC 2). Métodos Foi realizado exame citopatológico e CH2 para HPVar (Qiagen, Gaithersburg, Maryland, EUA) em 359 amostras em meio líquido (Sure Path, Becton Dickinson, TriPath Imaging, Burlington, NC, USA) coletadas de mulheres da região do Vale do Ribeira, durante julho de 2013 e setembro de 2015 com citologia anterior classificada como células escamosas atípicas de significado indeterminado (ASC-US), lesão intraepitelial de baixo grau (LSIL), células escamosas atípicas, não podendo excluir lesão de alto grau (ASC-H) e células glandulares atípicas (AGC). O exame histopatológico foi realizado em 179 mulheres. As avaliações de desempenho foram calculadas usando o teste de intervalo de confiança (IC) "exato" de Clopper-Pearson de 95% pelo software MEDCALC (Medcalc Software Ltd, Ostend, Bélgica). Resultados A frequência de≥ NIC 2 foi 11,7% (21/179). A CH2 para o HPVar e a citologia de repetição para a detecção ≥ NIC 2 obteve, respectivamente, sensibilidade de 90.5% (IC 95% = 69,6-98,8) e 90,5% (IC 95% = 69,6-98,8), especificidade de 65,8% (IC 95% = 57,9-73,2) e 43,7%, (IC 95% = 35,8-51,8), valor preditivo positivo de 26,0% (IC 95% = 21,4-31,3) e 17,6%, (IC95% = 14,9-20,6), e valor preditivo negativo de 98,1% (IC 95% = 93,3-99,5) e 97,2%, (IC 95% = 90,1-99,2). Conclusão No geral, a CH2 para HPVar aprimora o desempenho para detecção de ≥ NIC 2, sem comprometer a sensibilidade e proporciona maior margem de segurança do retorno ao rastreio trienal de mulheres com anormalidades citológicas prévias, sem≥ NIC 2 subjacente.

Abstract Objective To observe if the histopathological result of a conization performed after cervical adenocarcinoma in situ diagnosis is compatible with the histopathological analysis of a subsequent hysterectomy. Methods The present descriptive and observational research consisted of the analysis of the medical records of 42 patients who were diagnosed with in situ adenocarcinoma postconization. The analysis consisted of whether there was compatibility between the histopathological reports of conization and hysterectomy and if there was an association between adenocarcinoma in situ and another neoplasia (squamous disease). Interpretation of any immunohistochemistry reports obtained was also performed. In addition, clinical and epidemiological data were also analyzed. Results A total of 42 conizations were performed, 33 (79%) were cold knife conizations and 9 (21%) were loop electrosurgical excision procedures (LEEPs). Of the patients analyzed, 5 (10%) chose not to undergo subsequent hysterectomy to preserve fertility or were < 25 years old. Out of the 37 patients with adenocarcinoma in situ who underwent subsequent hysterectomy, 6 (16%) presented with residual disease. This findingprovedincompatiblewiththe finding of the conizations, which had ruled out invasive cancer. Conclusion The prevalence of adenocarcinoma in situ increased in the past years. There is still a large part of the medical literature that advocates the use of conservative treatment for this disease, even though it is common knowledge that it is a multifocal disease. However, the majority of studies advocate that hysterectomy should remain the preferred treatment for women who have already completed their reproductive purpose.

Resumo Objetivo Observar se o resultado proveniente de uma conização realizada após o diagnóstico de adenocarcinoma cervical in situ é compatível com a análise histopatológica da histerectomia. Métodos A pesquisa foi descritiva e observacional e consistiu na análise de prontuário de 42 pacientes que tiveram o diagnóstico de adenocarcinoma in situ obtidas por conização. Foram analisados se havia compatibilidade entre os laudos de conização e histerectomia, margens do cone, se havia associação com outra patologia (doença escamosa) e interpretação de eventuais laudos histoquímicos obtidos. Além disso, também foram analisados dados clínico-epidemiológicos. Resultados Foram realizadas 42 conizações, sendo 33 (79%) por cone clássico e 9 (21%) por cirurgia de alta frequência. Das pacientes analisadas, 5 (10%) não foram submetidas a histerectomia por desejarem manter a fertilidade ou por terem idade < 25 anos. Das 37 pacientes com adenocarcinoma in situ no exame prévio realizado e que foram submetidas à histerectomia posteriormente, 6 (16%) apresentaram doença residual após o procedimento cirúrgico, apresentando laudos do anatomopatológico pós-histerectomia incompatíveis com o achado na conização que atestava margens livres. Conclusão A prevalência do adenocarcinoma in situ vemaumentando cada vez mais. Ainda há uma grande parte da literatura que defende o uso do tratamento conservador para esta doença, mesmo sabendo que ela é uma doença multifocal e que pode estar presente mesmo em situações nas quais o anatomopatológico evidencie margens livres. Tendo em vista essas características, a maioria preconiza que a histerectomia continua a ser o tratamento preferencial nas mulheres que já completaram o seu intuito reprodutivo.

Abstract Objective To describe the referral for colposcopy in a Hospital in Brazil and the relative frequency of patients who benefited from it, considering the correct indications for the examination and its final diagnoses. Methods A retrospective study was performed in the colposcopy service database of the Hospital Universitário de Taubaté, Taubaté, state of São Paulo, Brazil. The frequency validated in the analysis of the medical records of women referred for clinical indication or cytological alteration, attended from March 2015 to March 2017. The population selected and analyzed included 256 results that were correlated to the cytological, clinical data and the result of the colposcopy. Results Of the women referred, 45% presented out of the age of screening according to the guidelines of cervical cancer screening, 8.6% being adolescents and young adults < 25 years old, and 36.4% of the patients being ≥ 65 years old. A total of 50% of the patients had no indication of colposcopy, that is, normal cytologies, benign changes, ectopia, cervicitis, atypical squamous cells of indeterminate significance (ASC-US) and low-grade intraepithelial lesion (LSIL) without persistence and normal clinical appearance. A total of 39.84% who underwent colposcopy had high-grade lesion or cancer results, thus benefiting from the adequate referral. Conclusion Most (60.16%) of the patients referred to the colposcopy service did not benefit from the referral for results without changes, such as negative colposcopies, histologies with no cervical intraepithelial neoplasm (CIN) or only CIN 1, or were out of the age for screening. These findings therefore demonstrate a significant number of unnecessary and inadequate referrals.

Resumo Objetivo Descrever os encaminhamentos para colposcopia em um hospital no Brasil e a frequência relativa dos pacientes que foram beneficiados, considerando as indicações corretas para o exame e seus diagnósticos finais. Métodos Foi realizado um estudo retrospectivo no banco de dados do serviço de colposcopia do Hospital Universitário de Taubaté, Taubaté, SP, Brasil. A frequência validou em análise de prontuários de mulheres encaminhadas por indicação clínica ou alteração citológica, atendidas no período de março de 2015 a março de 2017. A população selecionada e analisada incluiu 256 resultados que estavam correlacionadas aos dados citológicos, clínicos e com o resultado da colposcopia. Resultados Das mulheres encaminhadas, 45% apresentaram-se fora da idade de rastreamento conforme as diretrizes de rastreio de câncer de colo uterino, sendo que 8,6% eram adolescentes e adultas jovens < 25 anos de idade e 36,4% das pacientes tinham idade ≥ 65 anos. Um total de 50% das pacientes não possuía indicação de colposcopia, ou seja, citologias normais, de alterações benignas, ectopia, cervicite, células escamosas atípicas de significado indeterminado (ASC-US) e lesão intraepitelial escamosa de baixo grau (LSIL) sem persistência e aspecto clínico normal. Um total de 39,84% das pacientes que realizaram a colposcopia tiveram resultados de lesão de alto grau ou câncer e, dessa forma, se beneficiaram com o encaminhamento adequado. Conclusão A maioria (60,16%) das pacientes encaminhadas para o serviço de colposcopia não se beneficiou com o encaminhamento, por resultados sem alterações como colposcopias negativas, histologias com ausência de neoplasia intraepitelial cervical (NIC) ou apenas NIC 1, ou estavam fora da idade de rastreamento. Esses achados demonstram, portanto, significativo número de encaminhamentos desnecessários e inadequados.

Em relação ao EC, 71 (42%) apresentaram resultado negativo para lesão intraepitelial ou malignidade e 98 (58%) alguma anormalidade de células escamosas: 20 (11,8%) atipias; 22 (13%) lesão intraepitelial escamosa de baixo grau e 56 (32,6%) lesão intraepitelial de alto grau (HSIL). Cinquenta (29,6%) apresentaram positividade para HPV, destas 56,4% foram diagnosticadas com HSIL (p<0,01). Conclusão: Os resultados revelam alta frequência de HPV em amostras com alterações citopatológicas, em mulheres jovens e com grau de exposição ao HPV, reforçando a importância do papel da sua identificação precoce na investigação da carcinogênese cervical.(AU)

Background and Objectives: Cervical cancer is considered a worldwide public health problem. Its diagnosis is made through cytopathological examination and its development related to human papillomavirus (HPV) infection. This study aims to evaluate the profile of women treated at reference health centers in Porto Alegre, Rio Grande do Sul, as well as the relation of changes observed to cytopathological examination with the presence of HPV. Methods: This is a cross-sectional study carried out in women treated at basic health units and a referral clinic of a public tertiary hospital, from July 2014 to January 2017. Representative samples of the endo/ectocervix were collected to perform the cytopathological examination and investigated for the molecular presence of HPV. Results: 169 women with mean age between 31 and 40 years were analyzed, of whom 125 (74%) reported that the onset of sexual activity occurred in the 15-20 years age group, and 37.9% reported having had three to five sexual partners. In relation to cytopathological examination, 71 (42%) had a negative result for intraepithelial lesion or malignancy and 98 (58%) some squamous cell abnormality: 20 (11.8%) atypical; 22 (13%) low-grade squamous intraepithelial lesion and 56 (32.6%) high-grade intraepithelial lesion (HSIL). Fifty (29.6%) were positive for HPV, of which 56.4% were diagnosed with HSIL (p < 0.01). Conclusion: The results reveal a high frequency of HPV in samples with cytopathological changes, in young women and with a degree of exposure to HPV, reinforcing the importance of the role of its early identification in the investigation of cervical carcinogenesis.(AU)

Justificación y objetivos: El cáncer de cuello uterino se considera un problema de salud pública en todo el mundo. Su diagnóstico se realiza mediante el examen citopatológico (EC), y su desarrollo está relacionado con la infección por el virus del papiloma humano (VPH). Este estudio objetivó evaluar el perfil de mujeres atendidas en los centros de referencia en salud de Porto Alegre, Rio Grande do Sul (Brasil), así como la relación de las alteraciones observadas en el EC con la presencia del VPH. Métodos: Estudio transversal realizado en las mujeres atendidas por unidades de atención primaria y por una clínica ambulatoria de referencia del hospital público terciario en la ciudad de Porto Alegre, en el período de julio de 2014 a enero de 2017. Se recolectaron muestras representativas de endo/ectocérvice para realizar la CE, las cuales se clasificaron según el sistema Bethesda y se investigaron la presencia molecular del VPH. Resultados: Analizamos 169 mujeres con promedio de edad entre 31 y 40 años, de las cuales 125 (74%) informaron que el sexarche ocurrió en el rango de 15-20 años. La mayoría (37,9%) informó haber tenido de 3 a 5 parejas sexuales; y el 37,3% estaban usando anticonceptivos orales. Con respecto a la EC, 71 (42%) se clasificaron como negativos para lesión intraepitelial o malignidad; y el 98 (58%) tenían alguna anormalidad de células escamosas: 20 (11,8%) de atipias; 22 (13,0%) lesión intraepitelial escamosa de bajo grado y 56 (32,6%) lesión intraepitelial de alto grado (HSIL). La frecuencia de positividad del VPH encontrada fue de 50 (29,6%), de estas un 56,4% fueron diagnosticadas con HSIL (p<0,01). Conclusiones: Estos resultados revelan una alta frecuencia de VPH en muestras con alteraciones citopatológicas presentes en mujeres jóvenes con cierto grado de exposición al VPH, lo que refuerza la importancia de identificarse tempranamente en el análisis de la carcinogénesis cervical.(AU)

Opa-interacting protein 5 antisense transcript 1 (OIP5-AS1) is one kind of cytoplasmic long non-coding RNA (lncRNA), which has been demonstrated to play a critical function in multiple cancers. However, the detailed mechanism of OIP5-AS1 in the regulation of cervical cancer progression is still obscure. Here, we demonstrated that lncRNA OIP5-AS1 was upregulated in cervical cancer and was correlated with poor prognosis by bioinformatics studies. OIP5-AS1 depletion inhibited cell proliferation and promoted cell apoptosis in cervical cancer cells. Furthermore, we clarified that ROCK1 was the downstream effector of OIP5-AS1 and OIP5-AS1 acted as a molecular sponge of miR-143-3p. Finally, we verified that OIP5-AS1 exerted its function in the regulation of cervical cancer progression via interacting with miR-143-3p to regulate ROCK1 expression. Our study revealed novel mechanisms about how lncRNA OIP5-AS1 executed its function in cervical cancer and thus provided potential therapeutic targets for the disease.

ABSTRACT OBJECTIVES To determine the efficacy and safety of the use of cryotherapy, cold knife or thermocoagulation compared to Loop Electrosurgical Excision Procedure (LEEP) for the treatment of cervical intraepithelial neoplasia. METHODS Systematic review with meta-analysis of randomized controlled trials in women with cervical intraepithelial neoplasia undergoing treatment with cryotherapy, cold knife, or thermo-coagulation compared with LEEP, to estimate its efficacy and safety. The search was conducted on MEDLINE/PUBMED, Cochrane Central Register of Controlled Trials (CENTRAL) and Scopus, until September 2018. RESULTS The total of 72 studies were identified, of which only 8 studies met the inclusion criteria. The treatment of CIN with cold knife decreases the risk of residual disease compared with LEEP (RR, 0.54, 95%CI, 0.30-0.96, p = 0.04). The management of premalignant lesions with cryotherapy, compared with LEEP, increases the risk of disease recurrence by 86% (RR, 1.86, 95%CI, 1.16-2.97, p = 0.01), increases the risk of infections (RR, 1.17, 95%CI, 1.08-1.28, p < 0.001) and reduces the risk of minor bleeding by 51% (RR, 0.49, 95%CI) %, 0.40-0.59, p ≤ 0.001). CONCLUSIONS The treatment of premalignant lesions of cervical cancer with cold knife reduces the risk of residual disease. Nevertheless, cryotherapy reduces the risk of minor bleeding in the 24 hours after treatment and increases the risk of recurrence of disease and infections.

RESUMEN OBJETIVOS Evaluar la eficacia y seguridad del uso de crioterapia, cono frio o termo-coagulación en comparación con el procedimiento de escisión electroquirúrgica en asa (LEEP) para el manejo de neoplasias intraepiteliales cervicales. MÉTODOS Revisión sistemática de ensayos controlados aleatorizados en mujeres con neoplasia intraepitelial cervical en tratamiento con crioterapia, cono frio, o termo coagulación y LEEP, para estimar su eficacia y seguridad. La búsqueda se realizó en MEDLINE/PUBMED, Registro Cochrane Central de Ensayos Controlados (CENTRAL) y Scopus, hasta setiembre de 2018. RESULTADOS Se identificaron 72 estudios, ocho cumplieron los criterios de inclusión. Cono frio disminuyó el riesgo de enfermedad residual en comparación con LEEP (RR 0,54; IC del 95%, 0,30-0,96, p = 0,04). Crioterapia en comparación con LEEP incrementó el riesgo de recurrencia de enfermedad en un 86,0% (RR 1,86; IC del 95%, 1,16-2,97, p = 0,01) con un tiempo de seguimiento de seis a 24 meses, y de infecciones (RR, 1,17; IC del 95%, 1,08-1,28, p < 0,001); pero redujo el riesgo de sangrado menor en un 51,0% (RR 0,49; IC del 95%, 0,40-0,59, p ≤ 0,001). CONCLUSIONES Cono frio reduce el riesgo de enfermedad residual. Sin embargo, la crioterapia reduce el riesgo de sangrado menor en las 24 horas posteriores al tratamiento e incrementa el riesgo de recurrencia de enfermedad y de infecciones.

Cervical cancer is a common and fatal malignancy of the female reproductive system. Human papillomavirus (HPV) is the primary causal agent for cervical cancer, but HPV infection alone is insufficient to cause the disease. Actually, most HPV infections are sub-clinical and cleared spontaneously by the host immune system; very few persist and eventually develop into cervical cancer. Therefore, other host or environmental alterations could also contribute to the malignant phenotype. One of the candidate co-factors is the ß-catenin protein, a pivotal component of the Wnt/ß-catenin signaling pathway. ß-Catenin mainly implicates two major cellular activities: cell-cell adhesion and signal transduction. Recent studies have indicated that an imbalance in the structural and signaling properties of ß-catenin leads to various cancers, such as cervical cancer. In this review, we will systematically summarize the role of ß-catenin in cervical cancer and provide new insights into therapeutic strategies.

ABSTRACT OBJECTIVE: To verify the effect of the Pact for Health on premature mortality (30-69 years) attributed to cervical cancer in Brazil and its macroregions, using interrupted time series analysis. METHODS: Segmented regression was used to assess "change in level" and "change in trend" in premature mortality rates attributed to cervical cancer considering the post-Pact period (2010-2018), controlling by the pre-Pact period (1998-2006). Understanding the triennium 2007-2009 as essential for the adoption and implementation of the policy, it was excluded from the main modeling, but assessed in the sensitivity analysis. RESULTS: From 1998 to 2018, there were more than 119,000 deaths due to cervical cancer in women aged 30 to 69 years in Brazil. The Northern region experienced the highest rates (> 20 per 100,000). Comparing with baseline (1998-2006), segmented regression showed a progressive increase in changing trend from cervical cancer deaths in Brazil as a whole (coefficient = 0.513; 95%CI 0.430 to 0.596) and in the Southeast region (coefficient = 0.515; 95%CI 0.358 to 0.674), South region (coefficient = 0.925; 95%CI 0.642 to 1.208), and Midwest region (coefficient = 0.590; 95%CI 0.103 to 1.077). The Northeast region presented the most promising effects with immediate reduction in change level (-0.635; 95%CI −1.177 to −0.092) and progressive reduction in the changing trend of premature deaths (coefficient= −0.151; 95%CI −0.231 to −0.007). CONCLUSIONS: Premature mortality rates due to cervical cancer are high in Brazil and its macroregions. This interrupted time series was not able to reveal the effectiveness of initiatives related to the Pact for Health on premature deaths from cervical cancer nationally and in all macroregions equally. The best results are restricted to the Northeast region.

RESUMO OBJETIVO: Verificar o efeito do Pacto Pela Saúde na mortalidade prematura (30-69 anos) atribuída a câncer de colo uterino no Brasil e nas suas macrorregiões, utilizando modelagem de séries temporais interrompidas. MÉTODOS: A regressão segmentada foi usada para avaliar "mudança de nível" e "mudança de tendência" das taxas de mortes prematuras por câncer de colo uterino no período pós-Pacto (2010-2018), controlando pelo período pré-Pacto (1998-2006). Entendendo o triênio 2007-2009 como essencial para adesão e implantação da política ele foi excluído da modelagem principal, mas avaliado na análise de sensibilidade. RESULTADOS: De 1998 a 2018, houve mais de 119 mil óbitos por câncer de colo uterino, em mulheres de 30 a 69 anos, no Brasil. A região Norte experimentou as taxas mais altas (> 20 por 100 mil). Comparando à linha de base (1998-2006), a regressão segmentada mostrou progressiva elevação das mortes por câncer de colo uterino no Brasil como um todo (coeficiente angular = 0,513; IC95% 0,430 a 0,596) e nas regiões Sudeste (coeficiente = 0,515; IC95% 0,358 a 0,674), Sul (coeficiente = 0,925; IC95% 0,642 a 1,208), e Centro-Oeste (coeficiente = 0,590; IC95% 0,103 a 1,077). A região Nordeste apresentou os efeitos mais promissores com redução imediata no nível (-0,635; IC95% −1,177 a −0,092) e redução progressiva na tendência de mortes prematuras (coeficiente= −0,151; IC95% −0,231 a −0,007). CONCLUSÕES: As taxas de mortalidade prematuras por câncer de colo uterino são altas no Brasil e nas suas macrorregiões. Esta série temporal interrompida não foi capaz de revelar efetividade das iniciativas relacionadas ao Pacto pela Saúde sobre as mortes prematuras por câncer de colo uterino nacionalmente e tampouco em todas as macrorregiões igualmente. Os melhores resultados estão restritos à região Nordeste.

Rhabdomyosarcoma (RMS) is a rare solid tumor in childhood and adolescence. The higher incidence is predominant during the first two decades of life. According to the Intergroup RMS Study Group, the embryonal RMS (ERMS), botryoidal variant, constitutes a histological subtype characterized as a "grape-like" lesion of 2.0 cm to 9.5 cm. The treatment involves chemotherapy, surgery, and/or radiotherapy. We present the case of a 14-year-old female patient diagnosed with ERMS, botryoidal variant, which originated in the uterine cervix with vaginal externalization. The initial therapeutic approach comprised an initial prolapsed mass excision followed by Wertheim­Meigs surgery due to the tumor extension. No consensual protocol to ERMS treatment is found in the medical literature; however, a combined approach seems to offer a better result. The postoperative time period was uneventful and the patient followed an adjuvant therapy with vincristine, d-actinomycin, and cyclophosphamide. A comprehensive evaluation of the therapeutic options preserving the reproductive function­unfortunately not always possible­is part of a multi-disciplined care team concerning the pediatric patients.

Abstract Objective To analyze the factors associated with health-related quality of life (HRQoL) in women with cervical cancer (CC) in a single center in Rio de Janeiro, state of Rio de Janeiro, Brazil. Methods A cross-sectional study in women with a diagnosis of CC followed-up in the gynecology outpatient clinic of the Hospital do Câncer II (HCII, in the Portuguese acronym) of the Instituto Nacional de Câncer (INCA, in the Portuguese acronym). The data were collected from March to August 2015. Women with palliative care, communication/cognition difficulty, undergoing simultaneous treatment for other types of cancer, or undergoing chemotherapy and/or radiation therapy were excluded. For the evaluation of the HRQoL, a specific questionnaire for women with CC was used (Functional Assessment of Cancer Therapy - Cervix Cancer [FACT-Cx]). The total score of the questionnaire ranges from 0 to 168, with higher scores indicating a better HRQoL. Results A total of 115 women were included in the present study, with a mean age of 52.64 years old (standard deviation [SD] = 12.13). The domains of emotional (16.61; SD = 4.55) and functional well-being (17.63; SD = 6.15) were those which presented the worst scores. The factors that had an association with better HRQoL in women with CC were having a current occupation, a longer time since the treatment and diagnosis, and women who had undergone hysterectomy. Conclusion Considering the domains of HRQoL of the women treated for cervical cancer, a better score was observed in the domains of physical and social/family wellbeing. For most domains, better scores were found between those with a current occupation, with a longer time after the diagnosis and treatment, and among those who had undergone a hysterectomy.

Resumo Objetivo Analisar os fatores associados à qualidade de vida em mulheres com câncer de colo do útero tratadas em um hospital de referência no Rio de Janeiro, RJ, Brasil. Métodos Estudo transversal em mulheres com diagnóstico de câncer do colo do útero emseguimento ambulatorial no Hospital de Câncer II (HCII) do Instituto Nacional de Câncer (INCA). Os dados foram coletados no período de março a agosto de 2015. Foram excluídas as mulheres em cuidados paliativos, comdificuldade de comunicação/cognição, que estavam em tratamento simultâneo para outros tipos de câncer, ou em quimioterapia e/ou radioterapia. Para a avaliação da qualidade de vida relacionada à saúde, foi utilizado um questionário específico para mulheres com câncer de colo do útero (Avaliação Funcional da Terapia do Câncer - Câncer Cervical (FACT-Cx, na sigla em inglês). O escore total do questionário varia de 0 a 168, com escores mais altos indicando melhor qualidade de vida relacionada à saúde. Resultados Foram incluídas 115 mulheres com uma média de idade de 52,64 anos (desvio padrão [DP] = 12,13). Os domínios de questões emocionais (16,61; DP = 4,55) e de bem-estar funcional (17,63; DP = 6,15) foram os que apresentaram os piores escores. Os fatores que tiveram associação com melhor qualidade de vida relacionada à saúde em mulheres com câncer de colo do útero foram ocupação atual, maior tempo após o tratamento e diagnóstico, e mulheres que haviamsido submetidas a histerectomia. Conclusão Considerando os domínios da qualidade de vida relacionada à saúde de mulheres tratadas para câncer do colo do útero, foi observado melhor escore nos domínios de bem-estar físico e social. Para amaioria dos domínios, osmelhores escores foram observados entre aquelas com ocupação atual, com mais tempo após o diagnóstico e tratamento, além daquelas que se submeteram a histerectomia.

RESUMEN El cáncer cérvico uterino, causa alrededor de 250 000 muertes anuales en el mundo y alrededor de 400 en Cuba, a pesar del esfuerzo que realiza el MINSAP, a través del Programa de Pesquisaje. Con el mismo se puede obtener el diagnóstico de lesiones precursoras del cáncer de cuello uterino, este diagnóstico citológico se realiza en Cuba a través del método de Richard y Barron que demuestra que existe un progreso citológico aparente hasta llegar al cáncer, que comienza con neoplasia intraepitelial (NICI a NICIII y carcinoma in situ), hasta finalmente el cáncer invasor. Por otro lado existe el método de Bethesda que responde casi todas las interrogantes que la citología plantea para su enfrentamiento, evidentemente los mayores aportes y revisiones se enfocan al manejo de las citologías atípicas de significado incierto, ya que no sólo presentan un mayor número de posibles evaluaciones, sino que representan el mayor porcentaje de citologías alteradas y la inclusión del VPH en las lesiones de bajo grado. En Cuba todavía se clasifica por el método de Richard y no se utiliza el Bethesda. Por la alta incidencia de esta entidad el propósito de este trabajo es emitir consideraciones sobre la implementación del sistema de Bethesda en el diagnóstico citológico de lesiones precancerosas del cérvix.

ABSTRACT The cervical-uterine cancer causes almost 250 000 death a year around the world and around 400 in Cuba in spite of the efforts made by the Public Health Ministry through the Screening Program. With it, the diagnosis of lesions that are predecessors of the cervical cancer could be reached. This cytological diagnosis is carried out through the Richard and Barron method, showing that there is an apparent cytological progress leading to the cancer that begins with intraepithelial neoplasia (NICI and NICIII and carcinoma in-situ) and ends in the invasive cancer. From the other hand there is the Bethesda methods answering to all the questions cytology ask for confronting it. Obviously the biggest contributions and reviews are focused in the management of the atypical cytologies with uncertain significance since they not only have a higher number of possible evaluations, but also represent the highest percent of the altered cytologies and the inclusion of the HPV in low grade lesions. The classification in Cuba is still made by the Richard method and the Bethesda one is not used. Due to the high incidence of this entity, the aim of this article is exposing considerations on the implementation of the Bethesda system in the cytological diagnosis of cervix pre-cancerous lesions.

ABSTRACT OBJECTIVE To determine the distribution of sociodemographic, reproductive, clinical and lifestyle habits in the cohort of women diagnosed with cervical cancer, assisted at Inca between 2012 and 2014, according to the histological type. METHODS Retrospective observational study of a hospital cohort of 1,004 women diagnosed with cervical cancer. Data were obtained from the Inca hospital cancer registry, physical and electronic records. RESULTS The most frequent histological type was squamous cell carcinoma (83.9%). Approximately 70% of the women aged more than 40 years. The study includes non-white women (67.4%), with less than 8 years of education (51.9%), with onset of sexual activity up to 16 years of age (40.7%), who were pregnant before (95.5%), with more than one pregnancy (82.9%), and more than two children (52.7%); 45.8% of the women were smokers or former smokers. Cervical adenocarcinoma was positively associated with earlier staging (IA-IIA) (OR = 1.79; 95%CI 1.03-3.13), as well as women with ≥ 12 years of education (OR = 6.30; 95%CI 1.97-20,13), who had no children (OR = 3.81; 95%CI 1.20 - 12,08) or who had up to two children (OR = 1.74; 95%CI 1.05 - 2,87). CONCLUSIONS The difference between histological types is highlighted, suggesting that women with cervical adenocarcinoma may represent a distinct clinical entity of cervical neoplasia, which may require different approaches from those used in squamous cell carcinoma.

RESUMO OBJETIVO Determinar a distribuição das características sociodemográficas, reprodutivas, clínicas e de hábitos de vida na coorte de mulheres diagnosticadas com câncer cervical, atendidas no Inca entre 2012 e 2014, segundo o tipo histológico. MÉTODOS Estudo observacional retrospectivo de uma coorte hospitalar de 1.004 mulheres diagnosticadas com câncer cervical. Os dados foram obtidos pelo Registro Hospitalar de Câncer do Inca, prontuários físicos e eletrônicos. RESULTADOS O tipo histológico mais frequente foi o carcinoma de células escamosas (83,9%). Aproximadamente 70% das mulheres foram diagnosticadas com mais de 40 anos de idade. Houve a predominância de mulheres não brancas (67,4%), com menos de 8 anos de escolaridade (51,9%), com início da atividade sexual até 16 anos de idade (40,7%), que já engravidaram alguma vez na vida (95,5%), com mais de uma gestação (82,9%) e mais de dois filhos (52,7%); 45,8% das mulheres eram tabagistas ou ex-tabagistas. O adenocarcinoma cervical esteve positivamente associado ao estadiamento mais precoce (IA-IIA) (OR = 1,79; IC95% 1,03-3,13), assim como a mulheres com ≥ 12 anos de estudo (OR = 6,30; IC95% 1,97-20,13), que não tiveram filhos (OR = 3,81; IC95% 1,20-12,08) ou que tiveram até dois filhos (OR = 1,74; IC95% 1,05-2,87). CONCLUSÕES Destaca-se a diferença entre os tipos histológicos, sugerindo que as mulheres com adenocarcinoma cervical possam representar uma entidade clínica distinta de neoplasia cervical, podendo demandar abordagens diferentes das utilizadas no carcinoma de células escamosas.

Cervical cancer is one of the most common cancers among women around the world. However, the underlying mechanism involved in cervical cancer progression is incompletely known. In the present study, we determined the role of glycoprotein nonmetastatic melanoma protein B (GPNMB) in tumorigenesis of cervical cancer. According to the GEO database, we found that GPNMB expression was significantly higher in cervical cancer than in normal cervix epithelium. A similar pattern was observed in GPNMB expression in cultured cervical cancer cells and normal cervical epithelial cells. Compared with the control, GPNMB knockdown significantly decreased the proliferation and migration capacity, but enhanced the apoptosis capacity of SiHa and HeLa cells. Additionally, the activity of MMP-2 and MMP-9 were aberrantly increased in SiHa and HeLa cells compared with normal cervical epithelial cells, whereas their activities were strongly inhibited by GPNMB siRNA. Furthermore, Wnt/β-catenin signaling was activated by GPNMB in SiHa and HeLa cells. Increased MMP-2/MMP-9 expression was suppressed by Dkk-1, inhibitor of Wnt/β-catenin signaling, while it was enhanced by stimulator BIO. The proliferation, migration, and apoptosis capacity of HeLa cells were found to be affected by Dkk-1 and BIO to different extents. In conclusion, we demonstrated that GPNMB contributed to the tumorigenesis of cervical cancer, at least in part, by regulating MMP-2/MMP-9 activity in tumor cells via activation of canonical Wnt/β-catenin signaling. This might be a potential therapeutic target for treating human cervical cancer.
