ABSTRACT
SUMMARY OBJECTIVE: The radical change in the treatment of breast cancer has promoted the necessity for more comprehensive training of the professionals involved, ensuring the preservation of oncological safety while also allowing for cosmetic interventions to benefit breast cancer survivors. The aim of this study was to present the methods employed in the training of breast surgeons, highlighting the importance of oncoplasty and breast reconstruction. METHODS: A literature review was conducted in two databases, identifying articles related to medical education in the context of oncoplastic surgery and breast reconstruction. We also assessed the Brazilian experience in oncoplastic centers. RESULTS: The basis for educational discussions was derived from 16 articles. We observed approaches that included hands-on courses utilizing simulator models, porcine models, cadaver labs, and fellowship programs. Positive outcomes were observed in Brazil, a fact based on seven oncoplasty training centers for senior mastologists and five training centers for junior mastologists. From 2009 to 2023, an estimated 452 seniors and 42 juniors received training, representing approximately 30% of mastologists in Brazil who have acquired training and experience in oncoplasty. CONCLUSION: Despite the limited number of publications on training methods, oncoplastic centers have made significant progress in Brazil, establishing a successful model that can be replicated in other countries.
ABSTRACT
Abstract Objective: To compare the medical image interpretation's time between the conventional and automated methods of breast ultrasound in patients with breast lesions. Secondarily, to evaluate the agreement between the two methods and interobservers. Methods: This is a cross-sectional study with prospective data collection. The agreement's degrees were established in relation to the breast lesions's ultrasound descriptors. To determine the accuracy of each method, a biopsy of suspicious lesions was performed, considering the histopathological result as the diagnostic gold standard. Results: We evaluated 27 women. Conventional ultrasound used an average medical time of 10.77 minutes (± 2.55) greater than the average of 7.38 minutes (± 2.06) for automated ultrasound (p<0.001). The degrees of agreement between the methods ranged from 0.75 to 0.95 for researcher 1 and from 0.71 to 0.98 for researcher 2. Among the researchers, the degrees of agreement were between 0.63 and 1 for automated ultrasound and between 0.68 and 1 for conventional ultrasound. The area of the ROC curve for the conventional method was 0.67 (p=0.003) for researcher 1 and 0.72 (p<0.001) for researcher 2. The area of the ROC curve for the automated method was 0. 69 (p=0.001) for researcher 1 and 0.78 (p<0.001) for researcher 2. Conclusion: We observed less time devoted by the physician to automated ultrasound compared to conventional ultrasound, maintaining accuracy. There was substantial or strong to perfect interobserver agreement and substantial or strong to almost perfect agreement between the methods.

Introduction: High rates of breast cancer mortality have been reported for patients from public healthcare, in Brazil. This study aimed to obtain a panorama of breast cancer in public healthcare, based on a questionnaire sent to breast specialists. Methods: Active members of the Brazilian Society of Mastology (SBM) were invited to participate anonymously, from Aug-Oct 2023. Possible answers ranged from "This is not a problem" to "This is a very serious, very common problem". The primary endpoint of the study was the relative frequency of the answers. Results: Overall, 767 (44% of all SBM affiliated members) completed the questionnaire. Access to modern drugs was considered the most concerning problem, with 81.36% of respondents classifying this as "serious, frequently" or "very serious, very frequently", followed by access to diagnostic methods (64.53%), access to breast reconstruction (60.24%), delay in starting treatment (60.11%) and access to screening (51.76%). Conclusions: This is the first study to evaluate the perceptions of breast specialists on breast cancer care within SUS. The SBM has issued considerations and proposals aimed at reestablishing a minimally adequate standard of breast cancer diagnosis and treatment in public healthcare in Brazil. (AU)

Abstract In this integrative review, we aimed to describe the records of time devoted by physicians to breast ultrasound in a review of articles in the literature, in order to observe whether the automation of the method enabled a reduction in these values. We selected articles from the Latin American and Caribbean Literature in Health Sciences (LILACS) and MEDLINE databases, through Virtual Health Library (BVS), SciELO (Scientific Electronic Library Online), PubMed, and Scopus. We obtained 561 articles, and, after excluding duplicates and screening procedures, 9 were selected, whose main information related to the guiding question of the research was synthesized and analyzed. It was concluded that the automation of breast ultrasound represents a possible strategy for optimization of the medical time dedicated to the method, but this needs to be better evaluated in comparative studies between both methods (traditional and automated), with methodology directed to the specific investigation of this potentiality.
Resumo Na presente revisão integrativa, objetivamos descrever os registros de tempo dedicado pelos médicos à ultrassonografia mamária em revisão de artigos da literatura, visando observar se a automação do método possibilitou redução destes valores. Selecionamos artigos nas bases de dados Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e MEDLINE, através da Biblioteca Virtual em Saúde (BVS), Scientific Electronic Library Online (SciELO), PubMed e Scopus. Obtivemos 561 artigos e, após a exclusão de artigos duplicados e procedimentos de triagem, foram selecionados 9 artigos, cujas informações principais relativas à pergunta norteadora da pesquisa foram sintetizadas e analisadas. Foi concluído que a automação da ultrassonografia mamária representa uma possível estratégia de otimização do tempo médico dedicado ao método; porém, essa conclusão necessita ser melhor avaliada em estudos comparativos entre ambos os métodos (tradicional e automatizado), com metodologia direcionada à investigação específica desta potencialidade.

SUMMARY OBJECTIVE: The aim of this study was to evaluate the impact of study methodology and evaluation type on the selection of studies during the presentation of scientific events. METHODS: A prospective, observational, transversal approach was applied to a cohort of studies that were submitted for presentation at the 2021 Brazilian Breast Cancer Symposium. Three forms of criteria (CR) were presented. CR1 was based on six criteria (method, ethics, design, originality, promotion, and social contribution); CR2 graded the studies from 0 to 10 for each study, and CR3 was based on five criteria (presentation, method, originality, scientific knowledge, and social contribution). To evaluate the item correlation, Cronbach's alpha and factorial analysis were performed. For the evaluation of differences between the tests, we used the Kruskal-Wallis and post-hoc Dunn tests. To determine the differences in the study classifications, we used the Friedman test and Namenyi's all-pairs comparisons. RESULTS: A total of 122 studies were evaluated. There was also a good correlation with the items concerning criterion 1 (α=0.730) and 3 (α=0.937). Evaluating CR1 methodology, study design and social contribution (p=0.741) represents the main factor and CR3 methodology, and the scientific contribution (p=0.994) represents the main factor. The Kruskal-Wallis test showed differences in the results (p<0.001) for all the criteria that were used [CR1-CR2 (p<0.001), CR1-CR3 (p<0.001), and CR2-CR3 (p=0.004)]. The Friedman test showed differences in the ranking of the studies (p<0.001) for all studies (p<0.01). CONCLUSION: Methodologies that use multiple criteria show good correlation and should be taken into account when ranking the best studies.
ABSTRACT
Abstract Objective Nipple-sparing mastectomy (NSM) has been traditionally used in selected cases with tumor-to-nipple distance > 2 cm and negative frozen section of the base of the nipple. Recommending NSM in unselected populations remains controversial. The present study evaluated the oncological outcomes of patients submitted to NSM in an unselected population seen at a single center. Methods This retrospective cohort study included unselected patients with invasive carcinoma or ductal carcinoma in situ (DCIS) who underwent NSM in 2010 to 2020. The endpoints were locoregional recurrence, disease-free survival (DFS), and overall survival (OS), irrespective of tumor size or tumor-to-nipple distance. Results Seventy-six patients (mean age 46.1 years) (58 invasive carcinomas/18 DCIS) were included. The most invasive carcinomas were hormone-positive (60%) (HER2 overexpression: 24%; triple-negative: 16%), while 39% of DCIS were high-grade. Invasive carcinomas were T2 in 66% of cases, with axillary metastases in 38%. Surgical margins were all negative. All patients with invasive carcinoma received systemic treatment and 38% underwent radiotherapy. After a mean of 34.8 months, 3 patients with invasive carcinoma (5.1%) and 1 with DCIS (5.5%) had local recurrence. Two patients had distant metastasis and died during follow-up. The 5-year OS and DFS rates for invasive carcinoma were 98% and 83%, respectively. Conclusion In unselected cases, the 5-year oncological outcomes following NSM were found to be acceptable and comparable to previous reports. Further studies are required.
Resumo Objetivo A mastectomia poupadora do complexo areolo-mamilar (MPM) tem sido tradicionalmente utilizada em casos selecionados com distância tumor-mamilo > 2 cm e biópsia de congelação da base do mamilo negativa. Recomendar MPM em populações não selecionadas continua controverso. Este estudo avaliou os resultados oncológicos de pacientes submetidas à MPM em uma população não selecionada atendida em um único centro. Métodos Coorte retrospectivo incluindo pacientes não selecionadas com carcinoma invasivo ou carcinoma ductal in situ (CDIS) submetidas à MPM entre 2010 e 2020. Os desfechos incluíram: recorrência locorregional, sobrevida livre de doença (SLD) e sobrevida global (SG), independentemente do tamanho do tumor ou da distância tumor-mamilo. Resultados Setenta e seis pacientes (média: 46,1 anos de idade) (58 carcinomas invasivos/18 CDIS) foram incluídas. A maioria dos carcinomas invasivos era hormônio-positivo (60%) (superexpressão de HER2: 24%; triplo-negativo: 16%), enquanto 39% dos CDIS eram de alto grau histológico. Os carcinomas invasivos foram T2 em 66% dos casos, com metástases axilares em 38%. As margens cirúrgicas foram todas negativas. Todas as pacientes com carcinoma invasivo receberam tratamento sistêmico e 38% receberam radioterapia. Após um período médio de 34,8 meses, 3 pacientes com carcinoma invasivo (5,1%) e 1 com CDIS (5,5%) apresentaram recidiva local. Durante o acompanhamento, duas pacientes tiveram metástase à distância e vieram a óbito. As taxas de SG e SLD aos 5 anos para carcinoma invasivo foram de 98% e 83%, respectivamente. Conclusão Em casos não selecionados, os resultados oncológicos de 5 anos após MPM foram considerados aceitáveis e comparáveis a resultados anteriores. Estudos adicionais são necessários.

ABSTRACT We have previously reported the impact of covid-19 pandemic on breast cancer screening, in Brazil: among women aged 50-69 years, mammography attendance decreased by 42% in public healthcare (SUS), comparing 2019 and 2020. In this short communication, we wish to present: a) an update of the number of mammograms performed, in 2021; b) an exploratory analysis of the characteristics of the screened population between 2019 and 2021. A total of 1.675.307 mammograms were performed in 2021, nearly 15% lower than pre-pandemic levels. Almost a third, 29.5% of them, had intervals greater than three years. In accordance with our previous study, the number of patients with palpable lumps on physical exam increased. The consequences of postponing breast cancer screening during the pandemic are still uncertain. Unfortunately, as of December 2021, screening attendance has not resumed. On the contrary, our results show an increase in the fraction of women with mammography delayed beyond three years.

Introduction: Most of the data on metastatic breast cancer (MBC) originate from hospital-based studies or controlled trials involving specific populations and controlled treatments. In this respect, few population-based studies have analyzed the profile of MBC in low- and middle-income countries. Objective: To describe the epidemiological profile of women with de novo MBC using data from a population-based cancer registry (PBCR). Methods: An ecological study conducted in a PBCR in Goiânia, Brazil, for the 19952011 period. Women with MBC at diagnosis were included and the standardized incidence rate and annual percent change (APC) over the period were calculated. The women's clinical and demographic characteristics and data on diagnosis and treatment were analyzed. Results: Overall, 5,289 cases of breast cancer were registered in the Goiânia PBCR, 277 (5.2%) at metastatic stage. The adjusted incidence was 8.9/100,000 in 1995 and 6.04/100,000 in 2011 (APC: 1.1; p=0.6). Most of the patients (70.3%) were receiving care within the public healthcare system and the mean age at diagnosis was 54.7±14.5 years. Additional data for a subpopulation of 156 patients were identified at the city's two main treatment centers. According to immunohistochemistry, 53 women (67.1%) had hormone receptor-positive cancer. Of these, 14.0% (6/43) received endocrine therapy as first-line systemic treatment and 48.5% (17/35) as second-line treatment. A comparison of clinical data between the 19952003 and 20042011 periods revealed no significant differences in age, histological grade, locoregional staging, the presence of symptoms at diagnosis, or in treatment. Conclusion: This study population of women with MBC consisted predominantly of locally advanced tumors and the luminal-like subtype. The incidence rate of MBC in Goiânia did not change over the 17-year period. Most cases received chemotherapy as firstline systemic treatment irrespective of the tumor phenotype.
ABSTRACT
Introdução: No mundo todo, estima-se que aproximadamente 11 milhões de cirurgias plásticas sejam realizadas a cada ano. Indivíduos com diferentes necessidades e perfis sociodemográficos distintos têm utilizado meios semelhantes na busca dos prestadores de serviços médicos, modificando as relações de consumo. Assim, faz-se necessária uma análise mais detalhada sobre as características dos consumidores dos serviços de saúde relacionados à cirurgia plástica e sobre os fatores que impactam em sua tomada de decisão, uma vez que os pacientes e seus familiares precisam se sentir seguros ao buscar tratamento médico e os profissionais devem ser os facilitadores desse processo. Métodos: Trata-se de um estudo de vida real, prospectivo, observacional e descritivo, conduzido em um único centro hospitalar. Foram incluídos na amostra 501 pacientes submetidos a cirurgias plásticas, no período de junho a novembro de 2017, realizadas exclusivamente por cirurgiões especialistas pela Sociedade Brasileira de Cirurgia Plástica (SBCP). Foram avaliadas as características sociodemográficas, hábitos de vida e os critérios para a escolha do cirurgião. Resultados: A amostra foi composta predominantemente por mulheres adultas jovens, pardas, casadas, com índice de massa corpórea (IMC) normal, nível superior de escolaridade e pertencentes à alta classe média, cuja maioria mostrou-se fisicamente ativa e não revelou qualquer vício. O critério mais utilizado para a escolha do cirurgião plástico foi a indicação de amigos ou familiares. Conclusão: Este estudo produziu resultados confiáveis para a descrição das características sociodemográficas e hábitos de vida dos pacientes, permitindo identificar o fator mais relevante na escolha do cirurgião plástico.
Introduction: Around the world, approximately 11 million plastic surgeries are estimated to be performed each year. Individuals with different needs and sociodemographic profiles have used similar means to search for medical service providers, modifying consumer relations. Thus, is necessary a more detailed analysis of consumers' characteristics of health services related to plastic surgery and the factors that impact their decision-making, since patients and their families need to feel safe when seeking medical treatment, and professionals should be the facilitators of this process. Methods: This is a real-life, prospective, observational, and descriptive study conducted in a single hospital center. We included in the sample 501 patients submitted to plastic surgeries, from June to November 2017, performed exclusively by specialist surgeons by the Sociedade Brasileira de Cirurgia Plástica (SBCP). Sociodemographic characteristics, life habits, and criteria for the surgeon's choice were evaluated. Results: The sample consisted predominantly of young, brown, married adult women with average body mass index (BMI), higher education level, and belonging to the upper-middle class, most of whom were physically active and did not reveal any bias. The most used criterion for choosing the plastic surgeon was the indication of friends or family. Conclusion: This study produced reliable results for describing patients' sociodemographic characteristics and life habits, allowing the identification of the most relevant factor in the plastic surgeon's choice.
ABSTRACT
O câncer de mama atinge 2.1 milhões de mulheres todos os anos no mundo. No Brasil, são 66.280 novos diagnósticos, segundo estimativas do INCA (Instituto Nacional de Câncer). Esse é o tipo de tumor mais frequente em mulheres de todas as idades e, nos países menos desenvolvidos, a mortalidade em decorrência da doença ainda é grande. No Brasil, por exemplo, as mortes chegam a 18 mil por ano, o equivalente a um quarto do total de casos e, apesar da eficácia da mamografia no rastreamento da doença, vemos um aumento gradual na incidência com uma razão de crescimento que fica entre 20% e 30%.

OBJECTIVES: The Lewis-Y antigen is expressed in 44%-90% of breast cancers (BCs). The expression of the antigen in carcinoma tissue differs from that in normal tissues. This study aimed to evaluate the clinical benefit of the humanized anti-Lewis Y monoclonal antibody, hu3S193, in advanced hormone receptor-positive and Lewis Y-positive BC after administration of endocrine therapy (ET). METHODS: A single-arm phase II study was conducted in seven centers. Patients with advanced hormone receptor-positive BC who failed first-line ET were included. The inclusion criterion was the observation of tumoral expression of the Lewis Y antigen during immunohistochemistry. The treatment comprised hu3S193 antibody administration at weekly intravenous doses of 20 mg/m2 for 8-week cycles. The primary endpoint was the clinical benefit rate. ClinicalTrials.gov NCT01370239. RESULTS: The study stopped accrual following an unplanned interim analysis as the hu3S193 antibody lacked sufficient activity to justify continuation of the study. Twenty-two patients were enrolled, of whom 21 were included in the efficacy analysis. The clinical benefit rate was 19%, with four patients presenting with stable disease after 24 weeks. One patient with prolonged stable disease received medication for over 2 years. No partial or complete responses were observed. The median time to progression and overall survival was 5.4 and 37.5 months, respectively. CONCLUSIONS: The humanized anti-Lewis Y monoclonal antibody, hu3S193, exhibited insufficient activity in this cohort. However, the possibility of activity in a more strictly selected subgroup of patients with higher levels of Lewis Y tumoral expression cannot be overlooked.

Objective: To discuss the practical difficulties associated with breast cancer staging, especially in the context of populationbased cancer registries (PBCR). Methods: This is a short communication that discusses the importance and temporal evolution of breast cancer staging, as well as the limitations and new challenges associated with this process. Results: This study discusses the importance and temporal evolution of breast cancer staging, as well as the limitations and new challenges associated with this process. Minimal divergences in physical examination and disagreements in imaging tests can classify the patient in a higher or lower stage of the disease. In some population-based registries, up to 20% of the information regarding the clinical stage of breast cancer may be mistaken. Conclusion: We highlight the necessity for continuing education and constant training for all professionals involved in the breast cancer epidemiological context. The utilization of new technologies can help standardize the information and reduce the divergences related to cancer staging registry.
ABSTRACT
Diagnosis in psychiatry is a thorough and potentially artificial process. In this letter, we discuss this diagnostic process in the context of a young patient who underwent nipple-sparing mastectomy after falsifying a breast biopsy report revealing invasive ductal carcinoma. The secondary pathology revision was also forged by the patient and confirmed the diagnosis. The patient was summoned by the Service's board and admitted the falsification of breast cancer reports. After evaluation at the Psychiatric Service, changes in vital mood, psychosis, delusional activity and obsessive-compulsive symptoms were ruled out. In view of the growing demand for prophylactic mastectomy observed worldwide, similar cases may become more frequent.
ABSTRACT
ABSTRACT BACKGROUND: The largest radiological accident to occur in any urban area happened in Goiânia, Brazil, in 1987. OBJECTIVE: To evaluate the association between breast cancer incidence and ionizing radiation levels. DESIGN AND SETTING: Ecological study among residents of the city of Goiânia, Brazil. METHODS: The central region of Goiânia, with seven major sources of contamination from cesium-137, was defined as the study area. The addresses of women diagnosed with breast cancer were identified between 2001 and 2010. The data were geographically referenced and, using census data, the annual averages of crude incidence rates were estimated. The existence of clusters of new cases was ascertained by means of the Moran index. Correlations of radiometric measurements with the incidence were assessed using unconditional linear regression. RESULTS: A total of 4,105 new cases were identified, of which 2,233 were in the study area, and of these, 1,286 (57.59%) were georeferenced. The gross rates of total and referenced cases were 102.91 and 71.86/100,000 women, respectively. These were close to the average for Brazilian state capitals, which is 79.37/100,000 women. The cluster analysis showed slight correlations in three small sets of census tracts, but these were far from the sources of contamination. The scatter plot of points and the R2 value close to zero indicated that there was no association between the variables. CONCLUSION: This study reinforces the hypothesis that the ionizing radiation levels to which women living in Goiânia are now exposed to are not associated with the onset of new cases of breast cancer.

Objective: To compare the reproducibility of different methods for assessing the cosmetic outcome of breast reconstruction, which was assessed by different health professionals. Methods: Photographs of 270 breast cancer patients who had been submitted to breast reconstruction of some type were included. A plastic surgeon, a resident in plastic surgery, two mastologists, two residents in mastology, and two psychologists performed the evaluation. The modified Garbay and Harvard scales and the objective BCCT. core software program were used. Cohen's Kappa and Spearman correlation coefficients were calculated. Results: The mean age of the patients was 55.7 (±11.1) years. Overall, 145 women (53.7%) underwent partial breast reconstruction and 125 (46.3%), total breast reconstruction. The mean follow-up time was 63.7±45.6 months. By applying the Harvard scale, the interobserver reproducibility among the different professionals was minimal; whereas the Garbay scale had no agreement. The correlations between the BCCT.core software program and the Harvard and modified Garbay scales were moderate. Conclusion: Correlations between both the modified Garbay scale and the Harvard scale and the objective (BCCT.core) test were moderate. There was less interobserver variability with the Harvard scale compared to the modified Garbay scale.
Objetivo: Comparar a reprodutibilidade de métodos diferentes de avaliação dos resultados estéticos de cirurgias reconstrutivas da mama, por avaliadores distintos. Métodos: Foram incluídas fotografias de 270 pacientes portadoras de neoplasia da mama que passaram por cirurgias reconstrutivas da mama. As notas da avaliação foram dadas por um cirurgião plástico, um residente em cirurgia plástica, dois mastologistas, dois residentes em mastologia e dois psicólogos. Foram utilizadas as escalas de Harvard e Garbay modificada e a nota objetiva do programa BCCT.core. Foram calculados os índice Kappa de concordância interobservador e de correlação de Spearman. Resultados: A média de idade das pacientes foi de 55,7 anos (±11,1). No geral, 145 (53,7%) mulheres foram submetidas a tratamento conservador com cirurgia oncoplástica e 125 (46,3%) passaram por mastectomia e reconstrução total. A média de tempo de seguimento foi de 63,7±45,6 meses. Para a escala de Harvard, houve uma reprodutibilidade interobservador razoável para os diferentes profissionais, enquanto na escala de Garbay, a reprodutibilidade foi pobre entre os profissionais. De forma geral, a nota dada pelo programa BCCT.core correlacionou-se moderadamente com a escala de Harvard e a de Garbay modificada. Conclusão: As escalas de Harvard e de Garbay modificada correlacionam-se igualmente de forma moderada com o teste objetivo (BCCT.core). A escala de Harvard tem menor variabilidade interobservador, se comparada com a escala de Garbay.
ABSTRACT
Objective: To verify data-coding accuracy for ductal carcinoma in situ at the Goiânia population-based cancer registry in the Brazilian state of Goiás. Methods: Ecological time series analysis of cases coded as ductal carcinoma in situ in the state cancer database (ONCOSIS), considering data from the Goiânia population-based cancer registry, from 1994 to 2010. Results: Of 376 cases originally coded as ductal carcinoma in situ, 115 were excluded following a review of the pathology reports. These exclusions referred to cases of lobular carcinoma in situ (n=21), Paget's disease (n=4), invasive carcinoma (n=08), ductal carcinoma in situ associated with invasive carcinoma (n=14), microinvasive carcinoma (n=21), records on non-residents in Goiânia, and duplicated data (n=46). Conclusion: Many cases needed recoding and, as a consequence, altered the initial database. Standardizing pathology reports and training data collection staff are crucial steps to avoid omissions and errors when transcribing cases of ductal carcinoma in situ in a population-based cancer registry database.
Objetivo: Verificar a acurácia da codificação dos dados de carcinoma ductal in situ dentro do Registro de Câncer de Base Populacional de Goiânia, Goiás - Brasil. Métodos: Estudo ecológico de série temporal de casos codificados como carcinoma in situ da mama, pelo programa (ONCOSIS) do Registro de Câncer de Base Populacional de Goiânia, entre 1994 e 2010. Posteriormente realizouse busca individual dos laudos histopatológicos de CDIS. Resultados: De 376 casos de CDIS, foram excluídos 115 casos após a revisão dos laudos anatomopatológicosas. As exclusões referem-se a carcinoma lobular in situ (21), Doença de Paget (4), carcinoma invasor (08); CDIS associado a carcinoma invasor (14); microinvasor (21), pacientes com endereço fora de Goiânia e dados duplicados (46). Conclusão: Há um grande número de casos que precisam ser recodificados, alterando o banco inicial. A padronização de laudos e o treinamento dos coletadores são etapas importantes para que não haja informações desconhecidas ao transcrever o CDIS para as fichas do RCBP.
ABSTRACT
ABSTRACT We report the case of a 25-year-old female patient having a large lesion in the right breast. The core biopsy revealed a high-grade fusocellular neoplasm. Immunostains show no evidence of a specific line of differentiation. The patient underwent radical surgery and adjuvant treatment. Due to the immunohistochemical profile and the rosette arrangement in fusocellular injury, a molecular evaluation of translocations associated to the Ewing sarcoma (ES) was made. However, translocations commonly associated with this disease [t(11;22)(q24;q12)] were not observed. The present report can contribute to the diagnostic investigation of similar cases and to the pre-test orientation of the molecular evaluation.
RESUMEN Presentamos el caso de una paciente de 25 años con lesión voluminosa en mama derecha. La biopsia de la lesión mostró neoplasia fusocelular de alto grado; la inmunohistoquímica no ha determinado la histogénesis de la lesión. La paciente fue sometida a la cirugía radical y al tratamiento adyuvante. Ante el perfil inmunohistoquímico y la formación en roseta de la lesión fusocelular, se ha realizado una evaluación molecular de translocaciones asociadas al sarcoma de Ewing (SE); sin embargo no han sido observadas translocaciones comúnmente asociadas a esa patología [t(11;22)(q24;q12)]. El presente reporte puede ayudar en la investigación diagnóstica en casos similares así como orientar la evaluación molecular.
RESUMO Relatamos o caso de uma paciente, 25 anos de idade, portadora de lesão volumosa em mama direita. A biópsia da lesão evidenciou neoplasia fusocelular de alto grau; a imuno-histoquímica não revelou a histogênese da lesão. A paciente foi submetida à cirurgia radical e ao tratamento adjuvante. Diante do perfil imuno-histoquímico e do arranjo em roseta em lesão fusocelular, foi realizada avaliação molecular de translocações associadas ao sarcoma de Ewing (SE); entretanto não foram observadas translocações comumente associadas a essa patologia [t(11;22)(q24;q12)]. O presente relato pode contribuir para a investigação diagnóstica de casos semelhantes, bem como para a orientação pré-teste da avaliação molecular.
ABSTRACT
RESUMO Objetivo: avaliar o perfil de segurança e os resultados estéticos do 2-octilcianoacrilato versus sutura intradérmica com fio de nylon em cirurgias mamárias. Métodos: ensaio clínico randomizado, aberto, que avaliou a ocorrência de complicações, como deiscência, hematoma, infecção e reações alérgicas após o uso do 2-octilcianoacrilato ou do fio de nylon. Também foi analisado o tamanho das incisões, o tempo de fechamento da pele e o tempo cirúrgico total. O resultado estético foi avaliado após 40 e 180 dias da cirurgia, por meio da largura média da ferida operatória e por avaliação subjetiva conceitual (ótimo, bom, razoável ou ruim). Resultados: foram incluídas 79 pacientes, sendo 37 no grupo 2-octilcianoacrilato e 42 no grupo de sutura com fio de nylon. O estudo foi interrompido antes do término do recrutamento dos pacientes pela ocorrência de maior número de deiscências no grupo do adesivo (OR: 11,42; IC95%: 1,36-96,02; p=0,007). Em relação às demais complicações analisadas, ao tempo cirúrgico e ao resultado estético no pós-operatório, não se observaram diferenças significativas entre os grupos. A média do tamanho da ferida operatória foi maior no grupo do adesivo em relação ao grupo da sutura, mas não houve correlação entre o tamanho da ferida e o maior número de deiscências. Conclusão: o 2-octilcianoacrilato apresentou maior risco de deiscência em relação à sutura intradérmica, com resultados estéticos equivalentes.
ABSTRACT Objective: to evaluate the safety profile and aesthetic results of 2-octyl-cyanoacrylate versus intradermal nylon suture in breast surgeries. Methods: an open-label, randomized, clinical trial evaluating the occurrence of complications, such as dehiscence, hematoma, infection, and allergic reactions after the use of 2-octyl-cyanoacrylate or nylon thread. The size of the incisions, skin closure time, and total surgical time were also analyzed. The aesthetic outcome was evaluated at 40 and 180 days after surgery, by means of the average width of the surgical wound and by subjective conceptual assessment (optimal, good, reasonable, or poor). Results: 79 patients were included: 37 in the 2-octyl-cyanoacrylate group and 42 in the nylon suture group. The study was stopped before the end of patient recruitment due to the occurrence of a greater number of dehiscences in the adhesive group (OR: 11.42; 95%CI: 1.36-96.02; p=0.007). Regarding the other analyzed complications, the surgical duration and postoperative aesthetic result, no significant differences were observed between the groups. The mean operative wound size was greater in the adhesive group than in the suture group, but there was no correlation between wound size and the largest number of dehiscences. Conclusion: while the cosmetic outcomes with the two techniques were similar, there was a greater risk of dehiscence with the use of 2-octyl-cyanoacrylate compared to intradermal suturing.

Needles embedded in the breast are an unusual situation. It is reported the possibility of developing an abscess and the risk of migration of the needles. We report the case of a 38 year old woman with approximately 25 needles inserted in her breasts, bilaterally. According to the patient, the insertion occurred during the episode of a recent physical aggression; however, the hypothesis of self-mutilation could not be ruled out. She also referred the withdrawal of some needles at home and tried a surgical resection of others. Physical examination of the breasts revealed bilateral bruising, located in the upper inner quadrant of the left breast and diffusely in the right breast. Ultrasound examination showed needles in both breasts, associated with a hyperechoic area between 5 and 6h of the right breast, corresponding to palpable clinical area. An X-ray and chest tomography also revealed the presence of several needles in the breasts. At mammography, multiple intra-mammary needles and lymph nodes were diffusely distributed through the parenchyma, bilaterally. After discussing with the patient about the diagnosis and therapeutic options, we opted for clinical follow-up. Currently, the patient has moderate acyclic mastalgia, and is on clinical follow up for 55 months
Agulhas inseridas no parênquima mamário constituem uma situação incomum, podendo haver ocorrência de abscessos e o risco de migração das agulhas. Descrevemos o caso de uma paciente do sexo feminino, de 38 anos de idade, diagnosticada com aproximadamente 25 agulhas de costura em suas mamas, bilateralmente. Segundo a paciente, a inserção ocorreu durante episódio de agressão física recente; porém, a hipótese de automutilação não pôde ser descartada. A paciente também referiu a retirada domiciliar de algumas agulhas e a tentativa de retirada em outro Serviço. Ao exame físico das mamas, evidenciava-se equimose bilateral, localizada no quadrante súpero-medial da mama esquerda e difusamente na mama direita. O exame ultrassonográfico evidenciou agulhas em ambas as mamas, associadas à área hiperecoica entre 5 e 6h da mama direita, correspondente a área clínica palpável. A radiografia e a tomografia de tórax visibilizaram a presença de vários corpos estranhos nas mamas, de aspecto metálico, compatíveis com agulhas. Após discussão com a paciente acerca do diagnóstico e das opções terapêuticas, optou-se por conduta expectante. Após 55 meses, a paciente refere mastalgia acíclica moderada e mantém seguimento clínico no Serviço
