Neumatosis intestinal y neumoperitoneo: no siempre una indicación quirúrgica / Intestinal pneumatosis and pneumoperitonum: not al ways a surgical indication

Resumen La neumatosis intestinal y el neumoperitoneo no son entidades patológicas en sí mismas, son signos radio lógicos que resultan de alguna condición subyacente. En general, estos se asocian con procesos graves intra-abdominales que resultan en cirugías de urgencias con resecciones de intestino. A continuación, presentamos el caso de una mujer de 80 años, con diagnóstico de cáncer de mama estadio IV en tratamiento con ful vestrant y ribociclib, que ingresó a nuestro centro por dolor abdominal y vómitos. Se diagnosticó neumatosis intestinal y neumoperitoneo por lo que se procedió a laparotomía exploradora por sospecha de isquemia intestinal. No hubo evidencia de necrosis o perforación intestinal por lo que no se realizó resección. Evolucionó durante la internación de forma satisfactoria y en el control tomográfico al mes del egreso hubo resolución completa del cuadro. Si bien está descrito esta afectación en relación a los episodios de aumento de presión intraabdominal, como en la emesis, también se describió en pacientes con neoplasias, principalmente del tubo digestivo, ya sea por daño local o por toxicidad asociada a la quimioterapia. No encontramos reportes en la literatura de neumatosis intestinal vinculada a esta medicación antineoplásica en humanos. Probablemente en nuestro caso la etiolo gía haya sido multifactorial. Es posible que el ribociclib haya jugado un rol, ya sea por un mecanismo indirecto asociado a los vómitos y la inmunosupresión o directo sobre el enterocito debido a su mecanismo de acción celular no específico.

Abstract Pneumatosis intestinalis and pneumoperitoneum are not pathological entities in themselves, they are radiological signs that result from some underlying condition. In general, these are associated with serious intra-abdominal processes that result in emergency surgeries with bowel resections. Below, we present the case of an 80-year-old woman, diagnosed with stage IV breast cancer under treatment with fulvestrant and ribociclib, who was admitted to our center due to abdominal pain and vomiting. She was diagnosed with intestinal pneumatosis and pneumoperitoneum, so she underwent exploratory laparotomy for sus pected intestinal ischemia. There was no evidence of intestinal necrosis or perforation, so resection was not performed. She progressed satisfactorily during hospitalization and in the tomographic control one month after discharge there was complete resolution of the condition. Although this condition has been described in relation to episodes of increased intra-abdominal pressure, such as emesis, it has also been described in patients with neoplasms, mainly of the digestive tract, either due to lo cal damage or toxicity associated with chemotherapy. We found no reports in the literature of pneumatosis intesti nalis linked to this antineoplastic medication in humans. Probably in our case the etiology was multifactorial. It is possible that ribociclib played a role, either through an indirect mechanism associated with vomiting and im munosuppression or directly on the enterocyte due to its non-specific cellular mechanism of action.

Metastasis of breast cancer to the thyroid gland / Metástasis de cáncer de mama en glándula tiroides

Abstract Metastases to the thyroid gland from nonthyroidal malignant tumors are rare but significant. They are often asymptomatic, indicating advanced-stage primary tumors and poor prognosis. Although infrequently, breast cancer (BC) can metastasize to the thyroid gland. We present the case of a 56-year-old woman with a history of BC who pre sented with a nodular goiter. Physical examination and im aging revealed a thyroid nodule and cervical lymph nodes with suspicious features. Fine-needle aspiration biopsy (FNAB) confirmed the presence of atypical epithelial cells in the thyroid nodule and lymph nodes. Further evaluation, including positron emission tomography, histological biop sy, and immunohistochemistry, supported the diagnosis of metastatic BC to the thyroid gland. Due to the local extent of the disease, total thyroidectomy was not feasible. The treatment with ribociclib and letrozole was initiated, but unfortunately, the patient had an unfavorable progression with the development of metastasis in the nervous system. Metastatic carcinoma to the thyroid gland is rare but has increased due to improved diagnostic techniques. BC can metastasize to the thyroid. Diagnosis involves imaging, FNAB, and immunohistochemistry. Treatment options include surgery, radiotherapy, and chemotherapy, but the prognosis is generally poor.

Resumen Las metástasis en la glándula tiroides a partir de tu mores malignos no tiroideos son raras pero significativas. A menudo son asintomáticas, lo que indica tumores primarios en etapas avanzadas y un mal pronóstico. Aunque infrecuentemente, el cáncer de mama puede metastatizar en la glándula tiroides. Presentamos el caso de una mujer de 56 años con antecedente de cáncer de mama que consultó por bocio nodular. El examen físico y las imágenes revelaron un nódulo tiroideo y ganglios linfáticos cervicales con características sospechosas. La punción aspiración con aguja fina confirmó la presencia de células epiteliales atípicas en el nódulo tiroideo y los ganglios linfáticos. Una evaluación adicional, que incluyó tomografía por emisión de positrones, biopsia histológica e inmunohistoquímica, respaldó el diagnóstico de cáncer de mama metastásico en la glándula tiroides. Debido a la extensión local de la enfermedad, no fue factible realizar una tiroidectomía total. Se inició el tratamiento con ri bociclib y letrozol, pero desafortunadamente la paciente tuvo una progresión desfavorable con el desarrollo de metástasis en el sistema nervioso. El carcinoma metas tásico en la glándula tiroides es raro, pero ha aumentado debido a las técnicas de diagnóstico mejoradas. El cáncer de mama puede metastatizar en la tiroides. El diagnóstico implica imágenes, punción aspiración con aguja fina e in munohistoquímica. Las opciones de tratamiento incluyen cirugía, radioterapia y quimioterapia, pero el pronóstico generalmente es desfavorable.

Exploring human mammaglobin: as a possible diagnostic and prognostic indicator in breast cancer tissue

Breast cancer is a major global health issue, with high diagnosis rates worldwide, especially in less developed areas, leading to significant mortality rates. This review focuses on the molecular characteristics of breast cancer, emphasizing the role of human mammaglobin-A (hMAM-A) as a diagnostic and prognostic marker. hMAM-A, a dimeric protein from the secretoglobin family, is produced exclusively by breast tissue and shows elevated levels in breast cancer cases, making it a highly accurate marker for disease detection. The review also examines various factors influencing breast cancer, such as age, tobacco use, menopausal status, and hormone replacement therapy (HRT). Younger age at diagnosis is associated with poorer outcomes, highlighting the importance of early detection. Tobacco smoke increases mortality rates in breast cancer patients. Menopausal status affects molecular subtypes and risk factors, impacting treatment and prognosis. HRT has a complex relationship with breast cancer risk. The review concludes by discussing the need for novel biomarkers, including hMAM-A, to improve breast cancer diagnosis and management.

Breast self-examination: knowledge, awareness, and practices among females of reproductive age group

Background: Breast cancer occurs in an observable organ, thus awareness regarding its symptoms can help in its early detection and treatment. Although breast self-examination (BSE) is an old technique, evidence reveals many of females are not aware regarding this, and those with knowledge about breast cancer examination either fail to practice it or do so incorrectly. Methods: It was a cross-sectional exploratory survey. 505 females attending outpatient department (OPD) at selected tertiary care hospital were recruited in the study using simple random sampling. Each participant was given a set of validated questionnaires to answer. The questionnaire was designed to obtain information regarding socio demographic data, knowledge, awareness, and practice regarding BSE. All data were coded, validated, and analyzed utilizing both descriptive and inferential statistics techniques. Results: The study revealed that the largest proportion (42.06%) of subjects fell within the age range of 20-30 years. Total mean score of knowledge and awareness regarding breast self-examination was 9.68±3.5. Maximum 58.42% of the subjects had average knowledge and awareness followed by 23.96% having good knowledge and awareness and least (17.62%) had poor knowledge and awareness regarding BSE. Almost half i.e., 50.49% (255) of participants reported to perform BSE and 49.51% of participants had never practiced BSE. Conclusions: The study revealed that while participants had average knowledge levels, they showed low involvement in routine BSE. This underscores the need for educational interventions to promote BSE practices, identify risk factors and warning signs, and encourage early-stage management of breast cancer, ultimately contributing to primary prevention in healthcare.

Impacto del Score de Recurrencia de 21 genes (Oncotype DX®) sobre la toma de decisión en tratamiento adyuvante: un estudio multicéntrico y colaborativo / Impact of the 21-gene Recurrence Score (Oncotype DX®) on decision-making in adjuvant treatment: a multicenter and collaborative study

En la actualidad, más de la mitad de las pacientes con cáncer de mama receptor hormonal positivo recibe algún esquema de quimioterapia adyuvante. Sin embargo, sólo algunas de ellas obtendrían un beneficio real en términos de sobrevida. Las plataformas genómicas permiten un mejor entendimiento de la heterogeneidad tumoral entre carcinomas con receptores hormonales positivos, Her2 negativos, habiendo sido validadas como herramientas para identificar aquellas. pacientes que obtendrían un beneficio claro con el tratamiento quimioterápico. El objetivo de nuestro estudio es describir el uso de la plataforma genómica Oncotype Dx® y evaluar su impacto sobre la indicación del tratamiento adyuvante, evaluado principalmente a través del cambio de conducta en relación con la indicación final del tratamiento adyuvante. Material y método: Estudio multicéntrico observacional de cohorte llevado a cabo en distintas Unidades de Mastología de la República Argentina que utilizaran el Oncotype Dx* para esclarecer la indicación del tratamiento adyuvante en pacientes luminales Her2neu negativas en estadio inicial. Se registraron las decisiones relacionadas con el tratamiento antes y luego de realizar la prueba genómica. El objetivo secundario consistió en describir los eventos en aquellas pacientes en quiénes se solicitó dicho estudio. Resultados: Entre enero de 2013 y diciembre de 2018, 211 pacientes con carcinomas luminales A o B, Her2neu negativas realizaron el Oncotype Dx* y fueron incluidas en el estudio. Según nuestros registros, 40% de las pacientes experimentó un cambio en la indicación del tratamiento adyuvante luego de realizada la plataforma genómica. De aquellas pacientes que tenían indicación inicial de hormonoterapia según parámetros tradicionales clínico-patológicos, 24% recibió adicionalmente quimioterapia. En relación con las pacientes que tenían indicación inicial de quimio y hormonoterapia, 49% experimentó un cambio en la indicación de su adyuvancia pudiendo realizar únicamente hormonoterapia. En relación a los eventos descriptos en las pacientes participantes del trabajo, se registraron 4 muertes específicas por la enfermedad, una muerte por otra causa, 2 recaídas a distancia y un cáncer de mama contralateral. Conclusiones: En nuestra población de estudio el uso del Score de Recurrencia (RS) resultó clínicamente significativo en relación al cambio de conducta en la toma de decisión para adyuvancia. En consecuencia, para este grupo de investigadores, ha demostrado ser una herramienta de significativa importancia en la decisión del tratamiento adyuvante de pacientes con cáncer de mama temprano, luminal, Her2neu negativo(AU)

Objetive: Currently, over half of all patients diagnosed with hormone-receptor positive early stage breast cancer will receive some type of adjuvant chemotherapy (CHT), but only a few of them will actually benefit in terms of survival. Genomic platforms allow a better understanding of the heterogeneity among the different types of hormone receptor positive, her2 negative breast cancer, and have proven their validity as tools for identifying those patients who will obtain a clear benefit from CHT. The aim of our study was to analyze the use of the genomic platform Oncotype Dx® in our population and describe its impact on the decision of adjuvant treatment assessed through change in treatment decision. Material and method: this was a real world collaborative observational study, which was performed across several Breast Units in Argentina. Patients who underwent Oncotype Dx® testing to determine adjuvant treatment were included. Decisions regarding treatment were settled before and after the oncotype was performed by the tumor boards of each Breast Unit. Results: From January 2013 to December 2018, 211 patients with luminal A or B, her 2 negative breast cancer who underwent Oncotype Dx" testing were included. We found that treatment decisions were modified after Oncotype DX in approximately 40% of patients. In 24% percent of cases, chemotherapy was added to the initial treatment plan although endocrine therapy alone had initially been considered (potential subtreatment); and on the other hand, 49% of all patients were able to receive endocrine therapy only when, due to traditional prognostic factors, they would have received chemotherapy (potential overtreatment). Conclusions: In our population, we found that the use of the Recurrence Score was associated with a significant change in treatment recommendation We therefore consider it to be a very important tool and a decisive factor for the selection of adjuvant treatment in patients with hormone receptor positive, her2neu negative early breast cancer(AU)

La vigilancia es una de las estrategias más efectivas para ofrecer a este subgrupo de mujeres, sin embargo la adherencia a la misma puede ser dificultosa. Objetivo: Analizar la adherencia de las pacientes con Alto Riesgo Heredo-Familiar (ARHF) al programa específico de "Seguimiento de pacientes de Alto Riesgo" del Hospital Universitario Austral. Material y método: Se revisaron de forma retrospectiva datos de 104 mujeres sanas con ARHF que ingresaron al programa de vigilancia: "Seguimiento de pacientes de Alto Riesgo" del Hospital Universitario Austral en el período comprendido entre junio de 2016 a febrero de 2022. Resultados: La adherencia al programa fue total en 38 pacientes (36,54%) y parcial en 42 (40,38%). Se observó falta de adherencia en 24 pacientes (23,07%). La causa más prevalente fue la incomodidad al realizar la resonancia (54,16%). Analizando la adherencia según el año de ingreso al programa se observa una caída significativa a partir del 3er año de seguimiento y solo 48,98% completaron la sexta ronda. Conclusiones: La falta de adherencia observada fue significativa. Los datos demostrados apuntan a una necesidad de continuar desarrollando estrategias que faciliten el seguimiento(AU)

Introduction: Women with a genetic-familial predisposition have a higher risk of developing breast cancer. Surveillance is one of the most effective strategies to offer this subgroup of women, however adherence to it can be difficult. Objetive: To analize the adherence of patients with High Risk of Familial-Hereditary (HRFH) breast cancer to a specific program: "Follow-up in High Risk patients" of the Austral University Hospital. Material and method: Data from 104 women with HRFH who were admitted to the surveillance program: "Follow-up in High Risk patients" of the Austral University Hospital in the period from june 2016 to february 2022 were retrospectively reviewed. Results: Adherence to the program was complete in 38 patients (36,54%) and partial in 42 (40,38%). 24 (23,07%) patients had lack of adherence. The most prevalent cause was discomfort when performing the resonance (54,16%). When we analyze adherence according to the year of admission to the program, a significant drop is observed from de 3rd year of follow-up and only 48,98% completed round six. Conclusions: The observed lack of adherence was significant. The demonstrated data points to a need to continue developing strategies that facilitate monitoring(AU)

Permite la escisión tumoral con márgenes de resección más amplios y resultados oncológicos y estéticos aceptables. Creemos que es esencial brindar información precisa para ayudar a la paciente en la toma de decisiones sobre las consecuencias específicas de cualquier técnica oncoplástica. Conclusiones: La oncoplastia extrema debe ser utilizada solamente para casos seleccionados. Deberá ser evaluado por un equipo multidisicplinario, idealmente en el contexto de una unidad de mastología integrada por: cirujanos mastólogos, radioterapeutas, imagenólogos, oncólogos, anatomopatólogos y psicooncólogos. La técnica quirúrgica debe ser realizada preferentemente por cirujanos de mama con formación oncoplástica y reconstructiva de la mama(AU)

Introduction: Breast conservation has evolved and more oncoplastic techniques are used to obtain better cosmetic results. In addition, this technique allows wider excisions that prevents breast deformities by reconstructing large resection defects. Objetivo: Report with a clinical case: surgical strategy of multicentric breast cancer and oncoplastic breast-conservative surgery. Clinical case: A 72-year-old patient with large breasts with Grade III ptosis diagnosed with multicentric right mammary carcinoma Stage IA mT1cNO luminal A anatomical - prognosis. The patient's wishes to preserve the breast. Therapeutic mastoplasty + sentinel node (SLN) + mastopexy and contralateral reduction was decided. Pathology: right breast: multicentric infiltrating ductal carcinoma GC 0/3. Left breast: 1 focus of 2-mm infiltrating lobular carcinoma of the classic Nottingham score II type. free margin. Inmunohystochemistry: RE 95%, RP 95%, Her2 neu negative score 0 and ki67 2%. The case is discussed in the mastology unit, and we decided: Bilateral 3D radiotherapy and hormone therapy with anastrozole. Discussion: Therapeutic mastoplasty is considered a standard treatment option for selected patients, guaranteeing breast conservation with acceptable oncological safety, adequate aesthetic results and similar survival. It allows tumor excision with wider resection margins and acceptable oncological and cosmetic results. We believe that it is to provide accurate information to help the patient in making essential decisions about the specific consequences of any oncoplastic technique. Conclusions: Extreme oncoplasty should only be used for selected cases. It must be evaluated by a multidisciplinary team, ideally in the context of a mastology unit made up of: breast surgeons, radiotherapists, imaging specialists, oncologists, pathologists and psycho-oncologists. The surgical technique should preferably be performed by breast surgeons with oncoplastic and reconstructive training of the breast(AU)

Reticulohistiocitosis multicéntrica reveladora de cáncer de mama ductal in situ: reporte de caso con aspectos dermatoscópicos e histopatológicos / Multicentric reticulohistiocytosis revealing a ductal breast cancer in situ: a case report with dermoscopic and histopathological findings

La reticulohistiocitosis multicéntrica es una enfermedad inflamatoria, una histiocitosis de células no Langerhans, poco frecuente y de etiología desconocida. Se clasifica como multicéntrica al presentar compromiso multisistémico. La enfermedad afecta predominantemente a la piel y las articulaciones, pero es posible la afectación visceral. Las manifestaciones cutáneas se caracterizan por múltiples nódulos y pápulas de color eritemato-marronáceas, pruriginosas en la cara, manos, cuello y tronco. Se asocia a enfermedades autoinmunes y neoplasias malignas, observándose entre el 20 y el 30% de los pacientes con reticulohistiocitosis multicéntrica. Su diagnóstico se realiza sobre la base de la histopatología de tejidos afectados. Al ser una enfermedad poco reportada, no existe tratamiento estandarizado. Se reporta un caso de reticulohistiocitosis multicéntrica como manifestación paraneoplásica a un cáncer ductal de mama, siendo tratadas con éxito, sin recidivas luego de dos años de seguimiento. Pocos casos se han reportado en la literatura de reticulohistiocitosis multicéntrica asociado a cáncer mamario.

Multicentric reticulohistiocytosis is a rare non-Langerhans cell histiocytosis of unknown etiology. It is classified as multicentric because of multisystem involvement. The disease predominantly affects the skin and joints, but visceral involvement is possible. Multiple erythematous-brownish, pruritic nodules and papules on the face, hands, neck, and trunk are characteristic. It is associated with autoimmune diseases, or malignant neoplasms are seen in 20% to 30% of patients with multicentric reticulohistiocytosis. The diagnosis is based on histopathology of affected tissues. As it is an underreported disease, there is no standardized treatment. A case of multicentric reticulohistiocytosis is reported as a paraneoplastic manifestation of ductal breast cancer, being successfully treated with no recurrence after two years of follow-up. Few cases of multicentric reticulohistiocytosis associated with breast cancer have been reported in the literature.

Representações culturais do câncer de mama: uma revisão de escopo / Breast cancer cultural representations: a scoping review

Resumo O objetivo deste artigo é mapear a produção científica global sobre representações sociais ou culturais e câncer de mama no campo da saúde coletiva e discutir como esse fenômeno se apresenta na literatura. Foi realizada uma revisão de escopo, tendo como norte a seguinte pergunta: "Como representações culturais ou sociais no contexto do câncer de mama são descritas na produção científica global no âmbito da saúde coletiva?". As buscas foram realizadas em cinco fontes de literatura científica, sendo incluídos 45 estudos. O tratamento analítico seguiu a técnica de análise de conteúdo na modalidade temática. O acervo analisado pode ser tematizado nas seguintes categorias: (1) Comprometimento na imagem corporal e nas interações; (2) Espiritualidade; (3) Perda do controle da vida; (4) Seguir com a vida e (5) Associação a questões étnico-raciais. Apesar dos avanços da biomedicina, observa-se que nas representações do câncer de mama ainda permanecem metáforas associadas ao câncer no século passado. Conclui-se que, dentre outros aspectos, a atenção a mulheres com câncer de mama não pode ser pautada apenas pelas abordagens biomédica e epidemiológica, uma vez que essa doença é atravessada por saberes que competem com essas abordagens.

Abstract This article aims to map the global scientific production on social or cultural representations and breast cancer in Public Health and discuss how it is presented in the literature. We conducted a scoping review guided by the question: "How are cultural or social representations in the context of breast cancer described in the global scientific Public Health production?". We searched for works in five scientific literature sources and included 45 studies. The analytical process followed the content analysis technique in the thematic modality. The analyzed collection can be thematized into the following categories: (1) Compromised body image and interactions, (2) Spirituality, (3) Loss of control over life, (4) Going on with life, and (5) Association with ethnic-racial issues. Despite advances in biomedicine, we observed that representations of breast cancer still have metaphors associated with cancer in the last century. We conclude that, among other aspects, care for women with breast cancer cannot be guided only by biomedical and epidemiological approaches since this disease is traversed by knowledge that competes with these approaches.

Factors affecting the participation and utilization of breast cancer screening services among health care workers Kolar: a qualitative study

Background: India is going through epidemiologic transition with a shift of disease burden from communicable to non-communicable diseases. There is no organized screening programme for breast cancer in the country. Hence, a large proportion of women with cancer of the breast present in advanced stages of cancer. The integrated cancer control programme calls for early detection of cancer, opportunistic screening and cancer outreach camps that are to be promoted and carried out by health care providers. The objective of this study was thus designed to understand the various factors preventing the participation and utilisation of breast cancer screening. Methods: It was a qualitative method with two groups. The study was conducted between two taluks out of 6, Kolar and Bangarpete. All Angawadi workers and helpers aged more than 30 years were invited and those who have history of breast cancer and family history of breast cancer were excluded from the study. All the subjects who did not attend the screening were included to elicit the reasons for non-attendance. Results: The theme ‘barriers to screening uptake’ were broadly divided into three main categories- namely ‘worry’, ‘transport’ and ‘work commitment’. The sub-category ‘anxiety’ (31.9%) was reported to be the highest barrier and least was in the sub-category ‘no replacement’ (4.3%). The frequency of response categorized into different sub-categories. Conclusions: The reasons were identified by using ‘single question’ interview guide, and were categorized into ‘worry’, ‘transport’ and ‘work-commitment’. Barrier in ‘worry’ category was found to be highest.

The deep inferior epigastric artery perforator flap: a review

Breast cancer is recognized worldwide as a major health problem among women due to its high incidence and high mortality and morbidity rates. Breast reconstruction is an approach of great value for those patients who underwent mastectomy, impacting their quality of life and psychological stress. The deep inferior epigastric artery perforator (DIEP) flap was described as the preferred graft for breast reconstruction with an autologous flap by surgeons because it represented a decrease in complications for the time and obtained better results. DIEP flap reconstruction requires microsurgical skills as well as continuous monitoring of the patient to identify and resolve possible associated complications.

Assessment of knowledge and attitude on breast self-examination among female college students at Adichuchanagiri University

Background: Breast self-examination (BSE) is a preventive and easy way for people to keep an eye on the health of their breasts. People who routinely examine their breasts may be able to identify changes or abnormalities at an early stage, which may help in the early diagnosis of breast cancer. This self-care routine encourages an active approach to breast health and actively participate in their own well-being. Objectives of the study were assessment of the knowledge and attitude on breast self-examination among female college students, to assess the major barrier to perform breast self-examination, and to assess the impact of pharmacist mediated education program on breast cancer. Methods: This study is an interventional cross-sectional community based-survey. 1007 students’ female college students at Adichuchanagiri University in B. G. Nagar belonging to 18-33 years were chosen at random using stratified sampling. Knowledge, attitude on breast cancer. Data was analyzed using statistical package for the social science (SPSS) version 25. Results: In pre-test out of 1007 students 251 students had good knowledge about breast self-examination. In post-test 1006 members had good knowledge about breast self-examination. In our study statistical relation found between pre and post questionnaires (p=0.001). Conclusions: The study emphasizes how important it is to launch educational programs to increase awareness of breast self-examination. Additionally, awareness needs to be raised by removing known barriers. It is important to encourage women in the community to self-examine their breasts and to report any changes to a doctor as soon as possible.

Factors affecting breast cancer risk level and the prevalence of early diagnosis and screening in a group of Turkish women according to the Gail model

Background: Breast cancer, which is the most prevalent and common cause of death in women in the world and Turkey, is an important public health problem. The aim of this study is to evaluate the level of breast cancer risk according to the Gail model in a group of Turkish women and to determine the factors affecting the rates of early diagnosis and screening. Methods: A cross-sectional study in Turkey. A total of 1332 women who were aged between 40 and 69 participated. The study data were collected by using a questionnaire consisting of questions about sociodemographic characteristics, lifestyle, early diagnosis and screening behaviors, and Gail model questions for determining the breast cancer risk level. Results: The risk was higher in women who had their first childbirth at the age of ?30 years and had a first-degree relative with a history of breast cancer (p<0.05). There was a significant relationship between the breast self-examination behavior of the women and their age, education level, and family history of cancer, between their clinical breast examination behavior and age, education level, employment status, and chronic disease history, and between the behavior of getting a mammogram and age, education level, and chronic disease history (p<0.05). Conclusions: Accurate assessment of breast cancer risk and participation of women in screening programs reduce morbidity and mortality rates.

Clinico-pathological profile of breast cancer patients in a radiation therapy centre

Background: The aim of the study was to evaluate the clinico-pathological characteristics of patients with breast cancer at the Radiation Center of Bangabandhu Sheikh Mujib Medical University (BSMMU), a tertiary?care cancer center in Dhaka, Bangladesh. Methods: This descriptive study was conducted from March 2021 to February 2022 where patients receiving radiotherapy for breast cancer were included. Data were collected from face-to-face interviews with patients and from their investigation reports. Data regarding age, presenting symptoms, histological type, tumor size, involvement of regional nodes, hormonal receptor status, and human epidermal growth factor receptor 2 (HER2) amplification were recorded and then analyzed. Results: The mean age of the patients was 52.53 years. Most of the patients (93%) were multiparous and 62.24% were postmenopausal. The most common symptom was breast lump (91.6%). Infiltrating ductal carcinoma and lobular carcinoma were seen in 136 (95.1%) and 7 (4.9%) cases respectively. The TNM stage distribution was stage I, 6 (4.2%); stage II, 52 (36.36%); stage III, 76 (53.15%); and stage IV, 9 (6.29%). Locally advanced breast cancer constituted 42.66% of the cases. Among the patients 90 (62.94%) patients were ER/PR positive and 42 (29.37%) patients were HER2 positive. Triple negative breast cancer (TNBC) constituted 25.17% (36) of the study population. All receptors were positive in 25 patients (17.48%). Conclusions: Majority of our patients receiving breast radiotherapy at our center are middle aged and have advanced disease. TNBC and HER2 positive breast cancer are more common in our population.

Conclusiones: Investigaciones sobre el tema han concluido que las mujeres con un bajo nivel de escolaridad, que habitan en zonas rurales y pertenecen a estratos socioeconómicos bajos tienen mayor probabilidad de padecer esta patología.

ABSTRACT Introduction: In Latin America and the Caribbean breast cancer, it is the leading cause of death from malignant neoplasms in women, displacing cervical cancer in several countries. In Mexico, it is the second cause of death due to tumor processes in women over 25 years of age and 14,000 new cases are diagnosed each year. Objective: To determine the risk factors to which women with a family history of breast cancer may be exposed. Methodology: An integrative review was carried out where articles related to the topics of breast cancer, risk factors and care in women with a family history of breast cancer were searched. For the search, the Google Scholar, PubMed and Scielo databases were used. Search terms were selected based on the research question using the Concept, Population and Context (CPC) strategy. Results: From the Google Scholar, PubMed and Scielo databases, 42 articles were selected, finding that there is still a lack of knowledge regarding self-care practices, facing this public health problem in developing countries. Conclusions: Research on the subject has concluded that women with a low level of schooling, who live in rural areas and belong to low socioeconomic strata are more likely to suffer from this pathology.

Complicaciones por cirugía oncológica mamaria / Complications due to oncological breast surgery

RESUMEN Introducción: Cada año en América Latina, más de 200,000 mujeres son diagnosticadas con cáncer de mama. Como parte del tratamiento de esta enfermedad, la cirugía es uno de los pilares fundamentales. El acto quirúrgico es una experiencia extrema para el paciente y el cirujano, necesaria en esta patología para el tratamiento completo y, como todo acto médico, no está exento de complicaciones. En Paraguay no se cuentan con estadísticas sobre la prevalencia de las complicaciones debidas a cirugías por cáncer de mama, por lo que este trabajo tiene como principal objetivo establecer dicha frecuencia en un hospital de cuarto nivel de complejidad. Materiales y métodos: Estudio retrospectivo, observacional, de corte transversal. Muestreo no probabilístico de casos consecutivos. La selección de sujetos de estudios se realizó de la población de pacientes que fueron sometidos a cirugía por cáncer de mama, en el Hospital de Clínicas en el periodo enero de 2018 a agosto 2022, y que cumplan con los criterios de inclusión y exclusión. Todas las variables han sido extraídas de la ficha clínica y fueron documentadas en el formulario de registro de datos. Se esperaba una frecuencia de 42 % de complicaciones post quirúrgicas utilizando el programa estadístico EPIINFO 7 para un IC de 95% a precisión de 5%, el tamaño mínimo a incluir debía ser de 143 pacientes. Resultados: Se analizaron 203 historias clínicas de pacientes con diagnóstico de cáncer de mama que fueron sometidas a cirugía como parte del tratamiento, correspondientes al periodo comprendido entre enero de 2018 a agosto de 2022. Cumplieron con los criterios de inclusión 201 pacientes. Se registraron un total de 92 pacientes que presentaron alguna complicación relacionada a la cirugía, que corresponden 46 % del total de pacientes en el periodo de tiempo estudiado. De las complicaciones encontradas, 40 desarrollaron seromas, representando el 43% del total de pacientes con complicaciones; 18 pacientes tuvieron infección de la herida operatoria, representando el 20%. 7 pacientes presentaron dehiscencia de la herida operatoria, siendo el 7,5% del total; y 5 desarrollaron un hematoma, siendo el 5,3%. Entre otras complicaciones encontradas, 4 pacientes presentaron linfedema (4,3%), 4 dolor crónico (4,3%), 3 extrusión de prótesis mamaria (3,2 %), 2 de celulitis del miembro superior afecto (2,1%), 2 presentaron necrosis del complejo areola-pezón (2,1%), 1 sufrimiento de piel sin necrosis, 1 sufrimiento del complejo areola-pezón sin necrosis (1% ambos), 1 presentó fistula (1%), 1 disfunción del miembro superior homolateral (1%), y una contractura capsular (1%). Discusión: Se registraron 92 pacientes con una complicación post quirúrgica luego de una cirugía por cáncer de mama; representa así el 46% del total de pacientes estudiados. Esta prevalencia se corresponde con lo publicado en la literatura. En cuanto a las complicaciones encontradas, la más frecuente en nuestra revisión fue el seroma, que se presentó en un 40% de las complicaciones. Las publicaciones describen a esta como una de las complicaciones más frecuentemente relacionadas a la cirugía mamaria, con frecuencias que varían desde 18 al 86% según diversos autores. Conclusión: De 201 pacientes que cumplieron con los criterios de inclusión y exclusión, se registraron un total de 92 pacientes que presentaron alguna complicación relacionada a la cirugía, que corresponden 46 % del total de pacientes en el periodo de tiempo estudiado. La complicación más frecuente fue el seroma. Todos los hallazgos de este estudio se correlacionan con lo encontrado en la literatura.

Introduction: Every year in Latin America, more than 200,000 women are diagnosed with breast cancer. As part of the treatment of this disease, surgery is one of the fundamental pillars. The surgical act is an extreme experience for the patient and the surgeon, necessary in this pathology for complete treatment and, like any medical act, it is not exempt from complications. In Paraguay there are no statistics on the prevalence of complications due to surgeries for breast cancer, so the main objective of this work is to establish said frequency in a hospital of fourth level of complexity. Materials and methods: retrospective, observational, cross-sectional study. non-probabilistic sampling of consecutive cases. The selection of study subjects was made from the population of patients who underwent surgery for breast cancer, at the Hospital de Clínicas in the period January 2018 to August 2022, and who met the inclusion and exclusion criteria. All the variables have been extracted from the clinical record and were documented in the data recording form. A frequency of 42% of post-surgical complications was expected using the statistical program EPIINFO 7 for a CI of 95% with a precision of 5%, the minimum size to include had to be 143 patients. Results: 203 medical records of patients diagnosed with breast cancer who underwent surgery as part of the treatment, corresponding to the period from January 2018 to August 2022, were analyzed. 201 patients met the inclusion criteria. A total of 92 patients who presented some complication related to surgery were registered, corresponding to 46% of the total number of patients in the period of time studied. Of the complications found, 40 developed seromas, representing 43% of all patients with complications; 18 patients had surgical wound infection, representing 20%. 7 patients presented dehiscence of the surgical wound, being 7.5% of the total; and 5 developed a hematoma, being 5.3%. Among other complications found, 4 patients presented lymphedema (4.3%), 4 chronic pain (4.3%), 3 extrusion of breast prosthesis (3.2%), 2 cellulitis of the affected upper limb (2.1%), 2 presented necrosis of the nipple-areola complex (2.1%), 1 suffering from skin without necrosis, 1 suffering from the nipple-areola complex without necrosis (1% both), 1 presented fistula (1%), 1 homolateral upper limb dysfunction (1%), and capsular contracture (1%). Discussion: 92 patients with a post-surgical complication after surgery for breast cancer were registered; thus represents 46% of all patients studied. This prevalence corresponds to what has been published in the literature. Regarding the complications found, the most frequent in our review was seroma, which occurred in 40% of the complications. The publications describe this as one of the complications most frequently related to breast surgery, with frequencies ranging from 18 to 86% according to various authors. Conclusion: Of 201 patients who met the inclusion and exclusion criteria, a total of 92 patients who presented some complication related to surgery were registered, corresponding to 46% of the total number of patients in the period of time studied. The most frequent complication was seroma. All the findings of this study correlate with what is found in the literature.

Sonomammographic and sonoelastographic evaluation of benign and malignant breast lesions and its correlation with fine needle aspiration cytology

Background: Breast cancer affects 25.8% of women worldwide. Mammography and ultrasound have sensitivity, but invasive breast biopsies and aggressive biopsies are essential. Sonoelastography is a non-invasive imaging method that can measure tissue stiffness related to different pathologic conditions, such as cancer. Objective is to assess the diagnostic accuracy of sonomammography and sonoelastography in diagnosing breast lesions as benign or malignant in correlation with fine needle aspiration cytology (FNAC) as gold standard. Methods: This study was conducted on 52 female patients with breast mass and sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), kappa and p value of conventional gray scale ultrasound and ultrasonography (USG) elastography were calculated and compared with that of FNAC. Ultrasound was performed using grayscale and elastography mode on GE LOGIQ P9 ultrasound equipment with a 7-12 MHz linear-array transducer. All cases with breast lesions identified on ultrasound elastography underwent FNAC. Results: The sensitivity, specificity, PPV, NPV of sonoelastography were 78.5, 94.7, 84.6, 92.3 with kappa 0.75 and p value <0.0001. Similarly, sensitivity and specificity for strain ratio were 85.7 and 97.4, and that for size ratio were 85.7 and 100 respectively. These results are comparable to or better than results for conventional ultrasound. Conclusions: Breast elastography makes it easier to classify BIRADS 3 category lesions which are benign but still confused as malignant on conventional USG. BIRADS category 3 and 4 lesions with benign findings on sonoelastography can be downgraded to category 2 and 3 respectively thus reducing the number of false positive malignancy cases and biopsy.

Seroma formation after modified radical mastectomy: analysing risk factors and incidence

Background: Breast cancer is a prevalent form that affects women and is a leading cause of death among women. The development of seroma is a frequent complication that can arise after breast cancer surgery, and its underlying mechanisms are still not fully understood. Consequently, data was collected to analyze the occurrence and factors that contribute to the development of seroma in patients. We aimed to enhance our comprehension and ultimately discover methods to mitigate it. Methods: A prospective group research study was conducted on a sample of 86 female patients who underwent mastectomy from August 2020 to August 2023. This study was carried out as part of the senior residency program at Nalanda Medical College and Hospital in Patna, Bihar, India. Patients who develop seroma within four weeks of surgery are usually recommended to undergo, specifically ultrasonography, and radiological evaluation to determine the size. Results: 27 out of 86 patients (31%) were found to have seroma. Several factors are closely linked to the development of seroma. Factors that may contribute to increased risk The minimum age at which seroma production occurs following MRM ?56 or older, having a BMI of 26.50 or higher, a tumour measuring 4 cm or larger undergoing the removal of more than 12 lymph nodes, and having a level 3 axillary dissection. Conclusions: After surgery, a certain group of people in the study experienced seroma formation within four weeks. These individuals had undergone MRM. Age, BMI, tumour size, level 3 axillary dissection, the removal of more than 12 lymph nodes during surgery, and the occurrence of seroma after MRM were found to be positively correlated. There was no observed connection between seroma production and a range of factors, such as neoadjuvant chemotherapy, the timing of drain removal, shoulder workouts, and the use of breast bandages.

Mamografía con contraste: nuestra experiencia / Contrast-enhanced digital mammography: our experience

Resumen La mamografía contrastada (CEDM, contrast-enhanced digital mammography) es una herramienta nueva que ha ido implementándose de forma creciente. Aparece como alternativa a la resonancia magnética (RM), y al igual que esta, tiene como principio el uso de contraste endovenoso para explorar la angiogénesis tumoral. Combina la imagen de mamografía convencional (Mx) con la técnica de sustracción con energía dual poscontraste, lo que resulta en un incremento en la detección de cáncer de mama, en un tiempo corto de estudio y a un bajo costo. Es un método prometedor en casos seleccionados y de fácil lectura, siendo útil principalmente en pacientes con diagnóstico de cáncer de mama para detectar lesiones adicionales y determinar el tamaño tumoral, ayudando en la planificación quirúrgica, así como también en la evaluación de la respuesta a la neoadyuvancia. También en el seguimiento de pacientes operadas, para caracterizar lesiones dudosas en Mx y ecografía, o como alternativa ante contraindicación de la RM. El objetivo de este trabajo es valorar la utilidad de la mamografía contrastada en la práctica diaria y determinar sus principales indicaciones. Repasamos con casos propios las utilidades y características del método.

Abstract Contrast-enhanced digital mammography (CEDM) is an emerging tool that has been increasingly implemented. It appears as an alternative to magnetic resonance imaging (MRI), using intravenous contrast to explore tumor angiogenesis. It combines conventional mammography (Mx) with post-contrast dual energy subtraction technique, resulting in increased detection of breast cancer, in a short study time and at a low cost. It is a promising method in selected cases and easy to read, being useful mainly in patients with breast cancer to detect additional lesions and determine the tumor size, that helps surgical planning, as well as in the evaluation of post-neoadjuvant chemotherapy response in the follow-up of patients treated with surgery, to address inconclusive findings in screening mammogram, or as an alternative when MRI is contraindicated. The purpose of this article is to assess the usefulness of contrasted mammography in daily practice and to determine its main indications. We review with our own cases the applications and characteristics of this method.

Algoritmo para la selección de colgajos perforantes perimamarios en reconstrucción inmediata poscirugía conservadora / Algorithm to select chest wall perforator flaps in immediate conservative breast surgery reconstruction

RESUMEN Antecedentes: los colgajos perforantes perimamarios son de gran utilidad en la reconstrucción mamaria inmediata en cirugía conservadora. Objetivo: describir los resultados del empleo de un algoritmo sobre colgajos perforantes perimamarios en la reconstrucción mamaria inmediata después de cirugía conservadora por cáncer de mama. Material y métodos: se llevó a cabo un estudio retrospectivo descriptivo. Se revisaron las historias clínicas de las pacientes operadas entre enero de 2020 y diciembre de 2022 por carcinoma de mama con cirugía conservadora y que requirieron reconstrucción con colgajos perimamarios. Las indicaciones incluyeron déficit de volumen, defecto de contorno y asimetría. Se evaluó el pedículo vascular del colgajo mediante Doppler color en todos los casos, lo que permitió seguir un algoritmo para la selección de la mejor opción de colgajo. Resultados: se realizaron 20 colgajos en 19 pacientes. Promedio de edad: 52 años ± 11 (rango 30-76). No existieron complicaciones intraoperatorias. Una paciente requirió reoperación por compresión del pedículo vascular del colgajo por hematoma, con la pérdida parcial, y otro colgajo sufrió epidermólisis superficial. No hubo pérdidas totales de ningún colgajo. Todas recibieron radioterapia posoperatoria y no experimentaron pérdida de volumen ni retracciones. Con un promedio de seguimiento de 15 meses, las pacientes valoraron los resultados a 6 meses como excelente en 7, bueno en 11 y regular en 2. Conclusión: la selección de colgajos perforantes locales para corregir defectos mamarios después de cirugía conservadora, mediante el examen con Doppler color preoperatorio para la identificación del pedículo vascular y un algoritmo específico, permitió obtener resultados estéticos satisfactorios sin requerir elementos aloplásticos ni revisiones posteriores.

ABSTRACT Background: Chest wall perforator flaps are a good option for immediate breast reconstruction after conservative surgery. Objective: The aim of this study was to describe the clinical results of an algorithm for using chest wall perforator flaps for breast reconstruction after breast-conserving surgery for breast cancer. Material and methods: We conducted a descriptive and retrospective study. The information was retrieved from the medical records of the patients diagnosed with breast cancer who underwent breast-conserving surgery and required reconstruction using chest wall perforator flaps between January 2020 and March 2022. The indications included volume deficit, contour defect and asymmetry. The vascular pedicle of the flap was evaluated by color Doppler ultrasound in all cases, which allowed us to follow an algorithm for selecting the best flap option. Results: Twenty flaps were made in 19 patients. Mean age: 52 years ± 11 (range 30-76). There were no intraoperative complications. One patient required reoperation due to a hematoma with compression of the vascular pedicle of the flap with partial flap loss, and another flap presented superficial epidermolysis. There were no cases of complete flap loss. All the patients underwent postoperative radiation therapy without loss of volume or retractions. Mean follow-up was 15 months. At 6 months, patients rated the results as excellent, good, and fair in 7, 11, and 2 cases, respectively. Conclusion: The selection of local perforator flaps to correct breast defects after conservative surgery, using preoperative color Doppler ultrasound to identify the vascular pedicle and a specific algorithm, allowed us to obtain satisfactory aesthetic results without the need for alloplastic elements or subsequent revisions.
