ABSTRACT

Introducción: El cáncer de mama es la principal neoplasia en mujeres y se ha reportado un aumento de la incidencia en jóvenes menores a 40 años. El objetivo del presente estudio fue describir las características clínicas y patológicas, de pacientes con cáncer de mama invasor, ≤40 años, atendidas en un centro de referencia oncológico en Medellín-Colombia. Metodología: Se realizó un estudio transversal, realizado en la Clínica Vida (Fundación Colombiana de Cancerología), en el período enero del 2015 a diciembre del 2019. La muestra fue no probabilística, de pacientes con diagnóstico oncológico de cáncer de mama invasor. Se registró edad, tipo de cáncer, antecedentes familiares, recidivas y mortalidad. Se utiliza estadística descriptiva. Resultados: De 2332 casos de nuevos de cáncer de mama invasor, 261 se identificaron en mujeres ≤ 40 años, 11.19 % (IC 95 % 11.17-11.22 %), edad de 34.2 ± 4 años. 16.5 % en menores de 30 años, 40.2 % en edad de 30 a 45 años y 42.2 % en mujeres de 35 a 40 años. La presentación principal fue masa palpable auto detectada. El subtipo molecular Luminal A 16 %, Luminal B 48.3 %, Her2 enriquecido 11.2 % y Triple negativo 21.6 %. El 27 % tuvo algún antecedente familiar. La recidiva fue del 14 % y la mortalidad del 14.9 %. Conclusión: El 11 % de pacientes con cáncer de mama en esta serie corresponde a mujeres jóvenes, con una presentación en estadios más avanzados y biología molecular desfavorable, lo cual requirió un manejo más agresivo y radical. Esto resalta la importancia del diagnóstico oportuno en pacientes de lesiones mamarias en mujeres jóvenes.


Introduction: Breast cancer is the main neoplasm in women, and an increased incidence has been reported in young people under 40 years of age. The objective of the present study was to describe the clinical and pathological characteristics of patients with invasive breast cancer, ≤40 years old, treated at a reference oncology center in Medellín-Colombia. Methodology: A cross-sectional study was carried out by the Vida Clinic (Colombian Cancer Foun-dation) from January 2015 to December 2019. The sample was nonprobabilistic of patients with an oncological diagnosis of invasive breast cancer. Age, type of cancer, family history, recurrence, and mortality were recorded. Descriptive statistics are used. Results: Of 2332 cases of new invasive breast cancer, 261 were identified in women ≤ 40 years, 11.19% (95% CI 11.17-11.22%), age 34.2±4 years. 16.5% in those under 30 years of age, 40.2% in women between 30 and 45 years of age, and 42.2% in women between 35 and 40 years of age. The main presentation was a self-detected palpable mass. The molecular subtypes luminal A 16%, luminal B 48.3%, Her2 enriched 11.2%, and triple-negative 21.6%. A total of 27% had a family history. Recurrence was 14%, and mortality was 14.9%. Conclusion: Eleven percent of patients with breast cancer in this series were young women, with a presentation in more advanced stages and unfavorable molecular biology, which requires more aggressive and radical management. This highlights the importance of timely diagnosis in young women with breast injuries.

ABSTRACT

El carcinoma de mama es una enfermedad común, con efectos negativos significativos en la salud predominantemente femenina. Los linfocitos infiltrantes al tumor (TILs) son una manifestación de la respuesta inmune del huésped al cáncer. Este estudio revisa y resume los reportes bibliográficos relacionados con la eficacia pronóstica del porcentaje alto de TILs en cánceres de mama de tipos moleculares rico en HER2 y triple negativo. Se incluyeron estudios y revisiones en inglés buscados en la base de datos PubMed. Un mayor nivel de TILs se corresponde con mejor supervivencia libre de enfermedad tanto en los cánceres triple negativo como los ricos en HER2; por tanto, constituye un marcador histológico que debería ser utilizado rutinariamente en los análisis microscópicos de biop-sias de mama.


Breast cancer is a common disease affecting women, with significant health-related negative effects. Tumor-infiltrating lymphocytes (TILs) are recognized as manifestations of the host's antitumor im-munity. The following study reviews and summarizes reports on the effectiveness of prognosis of high levels of tumor-infiltrating lymphocytes on triple negative and HER2-enriched breast cancer molecular subtypes. Studies and reviews in English from Pubmed's database were included. A higher percentage of tumor- infiltrating lymphocytes is associated with better prognosis and survival rate of triple negative and HER2-enriched breast cancer. Consequently, such histological marker should be routinely used in the microscopic analysis of breast biopsies.

ABSTRACT

Introducción: El adenoma tubular de mama una patología benigna que se presenta en mujeres jóvenes como una masa unilateral que genera asimetría mamaria y se tiende a confundir con fibroadenoma gigante juvenil, diferenciándose en el estudio histopatológico. Es una patología muy rara, con excepcionales casos reportados en la literatura de mayor a 10 cm, motivo de presentación de este caso. Caso clínico: Presentamos el caso de una mujer de 21 años de edad con una masa de10 cm aproximadamente en la mama derecha, de 1 año de evolución con crecimiento paulatino, sin síntomas asociados. El examen físico sin hipertrofia de ganglios axilares. Taller diagnóstico: La paciente fue sometida a una exéresis quirúrgica reportando en el estudio patológico definitivo un adenoma tubular de mama. Conclusión: Como conclusión se trata de una patología poco frecuente, pero debemos conocerla y tener un mínimo de sospecha diagnóstica para evitar confusiones con patología mamaria maligna.


Introduction: Tubular adenoma of the breast is a benign pathology in young women as a unilateral mass that generates breast asymmetry and tends to be confused with giant juvenile fibroadenoma, differing in the histopathological study. It is a very rare pathology, with exceptional cases reported in the literature of greater than 10 cm, which is the reason for presenting this case. Clinical case: We present the case of a 21-year-old woman with a mass of approximately 10 cm in the right breast, of 1 year of evolution with gradual growth, without associated symptoms. Physical examination showed no axillary node hypertrophy. Diagnostic workshop: The patient underwent surgical excision, reporting a tubular adenoma of the breast in the definitive pathological study. Conclusion: It is a rare pathology, but we must know it and have a minimum of diagnostic suspicion to avoid confusion with malignant breast pathology.

ABSTRACT

Objetivo: determinar la existencia de inequidades de acceso al diagnóstico y tratamiento del cáncer de mama en mujeres de Colombia y describir los principales factores de riesgo asociados. Metodología: se realizó una búsqueda sistemática con los términos: "neoplasias de la mama" AND "inequidades de salud" OR "inequidades del estado de salud" OR "factores socioeconómicos" AND "Colombia", en las bases de datos Pubmed (Medline), Scielo, Cochrane, EBSCO, Ovid, Elsevier, Lilacs, Imbiomed, en español, inglés y portugués, publicados desde 1 de enero 2000 al 31 de octubre de 2019. Resultados: fueron seleccionadas 14 publicaciones. Se identificó que el estrato socioeconómico, el nivel educativo y el tipo de aseguramiento, en la mayoría de los estudios, se relacionan con las inequidades en cuanto a la enfermedad, con efectos variables sobre el riesgo de cáncer de seno e impacto sobre la detección temprana y el tratamiento. Estas variables influyen sobre la supervivencia total y sobre la libre de enfermedad. Conclusiones: se identifican inequidades en salud en las pacientes con cáncer de mama en Colombia. Los factores identificados son el tipo de aseguramiento, el estrato socioeconómico bajo y la escasa formación escolar, que implican retraso en el diagnóstico y empeoran la condición clínica y la calidad de vida de las pacientes.


Objective: To determine the existence of disparities in access for diagnosis and treatment in women diagnosed with breast cancer in Colombia, and to describe the main associated risk factors. Methodology: A systematic search was conducted with the terms "Breast neoplasms" AND "Health disparities" OR "Health status disparities" OR "Socioeconomic factors" AND "Colombia", in the Pubmed databases (Medline), Scielo, Cochrane, EBSCO, Ovid, Elsevier, Lilacs, Imbiomed, in Spanish, English, and Portuguese, published from January 1, 2000 back to October 31, 2019. Results: 14 publications were selected for the writing of the manuscript. It was identified that the socioeconomic level, the level of education and the type of insurance, in most of the studies, showed significant association to disparities in the disease. They also had variable effects on the risk of breast cancer and an impact in its early detection and treatment. These factors influence the full survival of the patient and their becoming disease-free. Conclusions: Health disparities of patients with breast cancer in Colombia are identified. Factors such as type of insurance, socioeconomic level, educational level were identified, which impact the delay in diagnosis and worsen the clinical condition and the quality of life of the patients.

ABSTRACT

El angiosarcoma es un tumor vascular maligno poco frecuente. Constituye menos del 2% de todos los sarcomas. Existen varias formas clínicas, una es la producida después de radioterapia, en pacientes que fueron tratadas por un cáncer de mama, con cirugía conservadora y radioterapia. Se presenta como un sarcoma de alto grado, localizado en la piel o en el tejido subcutáneo y, ocasionalmente, el parénquima mamario. El único tratamiento curativo es la cirugía, con tendencia a la recurrencia y a hacer metástasis hematógena, el pronóstico es malo, con alta tasa de mortalidad.


Angiosarcoma is a rare malignant vascular tumor. It constitutes less than 2% of all sarcomas. There are several clinical forms; the one produced after radiation therapy is that associated with patients who were treated for breast cancer with conservative surgery and radiation therapy. It presents as a high-grade sarcoma located on the skin or the subcutaneous tissue and, occasionally, the breast parenchyma. The only curative treatment is surgery, with a tendency to recurrence and visceral hematogenous metastasis, with a poor prognosis and a high mortality rate.

ABSTRACT

En el más reciente número de esta revista se publicó el estudio titulado "Lesiones papilares de mama: estudio clínico-patológico y sobrepronóstico en 144 casos de Medellín, Colombia", donde se hace un excelente acercamiento sobre este tipo de lesiones. Se conoce que las lesiones papilares de la mama son entidades poco frecuentes en la práctica cotidiana, con una representación del 10% de las entidades benignas y solo un 1% de las entidades malignas. Su manifestación clínica habitual es la secreción serosanguinolenta, unilateral, sin masas palpables y en los estudios de imagen suelen mostrarse como lesiones únicas o múltiples de localización retroareolar. El diagnostico anatomopatologico no es sencillo en estudios por punción, bien sea con aguja fina o por aguja gruesa y, por lo general, se requiere de la escisión de la lesión para obtener un diagnóstico más certero.

ABSTRACT

Abstract This study aimed to analyze the role of period, geographic and socio demographic factors in cancer-related mortality by prostate, breast, cervix, colon, lung and esophagus cancer in Brazilians capitals (2000-2015). Ecological study using data of Brazilian Mortality Information. Multilevel Poisson models were used to estimate the adjusted risk of cancer mortality. Mortality rate levels were higher in males for colon, lung and esophageal cancers. Mortality rates were highest in the older. Our results showed an increased risk of colon cancer mortality in both sexes from 2000 to 2015, which was also evidenced for breast and lung cancers in women. In both genders, the highest mortality risk for lung and esophageal cancers was observed in Southern capitals. Midwestern, Southern and Southeastern capitals showed the highest mortality risk for colon cancer both for males and females. Colon cancer mortality rate increased for both genders, while breast and lung cancers mortality increased only for women. The North region showed the lowest mortality rate for breast, cervical, colon and esophageal cancers. The Midwest and Northeast regions showed the highest mortality rates for prostate cancer.


Resumo Este estudo teve como objetivo analisar o papel de fatores temporais, geográficos e sociodemográficos na mortalidade por câncer de próstata, mama, colo do útero, cólon, pulmão e esôfago nas capitais brasileiras (2000-2015). Estudo ecológico utilizando informações brasileiras de mortalidade. Modelos de Poisson multinível foram usados ​​para estimar o risco ajustado de mortalidade por câncer. Os níveis de mortalidade foram maiores em homens para câncer de cólon, pulmão e esôfago. As taxas de mortalidade foram mais altas nos idosos. Nossos resultados mostraram risco aumentado de mortalidade por câncer de cólon em ambos os sexos de 2000 a 2015, o que também foi evidenciado para câncer de mama e de pulmão em mulheres. Em ambos os sexos, o maior risco de mortalidade para câncer de pulmão e esôfago foi observado nas capitais do Sul. As capitais do Centro-Oeste, Sul e Sudeste apresentaram o maior risco de mortalidade por câncer de cólon tanto para homens quanto para mulheres. A taxa de mortalidade por câncer de cólon aumentou para ambos os sexos, enquanto a mortalidade por câncer de mama e de pulmão aumentou apenas para as mulheres. A região Norte apresentou a menor taxa de mortalidade por câncer de mama, colo do útero, cólon e esôfago. As regiões Centro-Oeste e Nordeste apresentaram as maiores taxas de mortalidade por câncer de próstata.

ABSTRACT

SUMMARY OBJECTIVE: The stroma surrounding the tumor cells is important in tumor progression and treatment resistance, besides the properties of tumor cells. Studies on the tumor stroma characteristics will contribute to the knowledge for new treatment approaches. METHODS: A total of 363 breast cancer patients were evaluated for the tumor-stroma ratio. The percentage of stroma was visually assessed on hematoxylin-eosin stained slides. The cases of tumor-stroma ratio more than 50% were categorized as tumor-stroma ratio high, and those less than 50% and below were categorized as tumor-stroma ratio low. RESULTS: Tumor-stroma ratio-high tumors had shorter overall survival (p=0.002). Disease-free survival tended to be shorter in tumor-stroma ratio-high tumors (p=0.082) compared with tumor-stroma ratio-low tumors. Tumor-stroma ratio was an independent prognostic parameter for the total group of patients (p=0.003) and also axillary lymph node metastasis and tumor-stroma ratio was statistically associated (p=0.004). Also, tumor-stroma ratio was an independent prognostic parameter in node-positive Luminal A and B subgroups for overall survival (p<0.001). CONCLUSION: Tumor-stroma ratio is an independent prognostic parameter that can be evaluated quite easily in all molecular subtypes of all breast cancers and does not require extra cost and time to evaluate.

ABSTRACT

SUMMARY OBJECTIVE: The aim of this study was to evaluate the perception of the aesthetic result of breast reconstruction surgery from the perspective of plastic surgeons compared with physicians who are not specialists in plastic surgery. METHODS: Twenty patients who underwent breast reconstruction after mastectomy had their aesthetic results evaluated by 16 plastic surgeons and 16 nonplastic physicians, yielding a total of 620 ratings (320 ratings from plastic surgeons and 320 ratings from other specialists). For all analyses, the level of rejection adopted for the null hypothesis was 5% (p-value <0.05). RESULTS: Significant differences were observed between the two groups. On average, medical professionals who specialized in plastic surgery always obtained higher scores than other physicians. However, no significant differences were found in the assessment of the aesthetic outcome of breast reconstruction according to the sex of the rating medical professional for any of the assessments considered in this study. A strong positive linear correlation between the time since training in the medical specialty of plastic surgery (r=0.750, p=0.001) and the mean aesthetic outcome score was observed in this study. CONCLUSION: Plastic surgeons assessed the aesthetic results of breast reconstruction more positively than nonplastic physicians.

ABSTRACT

OBJECTIVE@#We employed a multidisciplinary approach incorporating theoretical ideas, clinical experience, psychology, physiology, traditional Chinese medicine (CM), modern practice of CM, and oncology to explore the effect of patients' repression of negative emotions and traumatic events on breast cancer (BC) pathogenesis.@*METHODS@#BC female patients, older than 18 years of age, with available pathology reports who were treated at Rabin Medical Center were recruited. All participants completed questionnaires regarding medical history, behavioral tendencies, negative emotions, trauma, symptoms, and pathology (from a CM perspective). Data on tumor characteristics were collected from the pathology reports. The associations were examined using hierarchical binary logistic regressions.@*RESULTS@#A total of 155 BC patients were enrolled. The median age was 52 years, with a range of 26-79; 95% were mothers; 28% had estrogen receptor (ER)-negative BC, 52% had progesterone receptor (PR)-negative BC, 48% had human epidermal growth factor receptor 2-negative BC, and antigen Ki-67 ≥ 20% was reported for 52% of tumors. Statistically significant associations were found between the emotional markers (sense of motherhood failure, and lack of self-fulfillment), avoidance behavior, and physical symptoms that are related to emotional repression based on CM. Significant associations were also found between variables associated with physical symptoms of emotional repression, which involves the production and accumulation of non-substantial phlegm (i.e., "high-lipid Qi-like microscopic phlegm"), avoidance behavior which unconsciously uses "high-lipid Qi-like microscopic phlegm" in order to achieve emotional repression, and tumor parameters including tumor grade, PR status, and Ki-67. Patients with higher levels of "high-lipid Qi-like microscopic phlegm" were more likely to have tumors with worse prognosis (PR-negative, higher grade, and higher Ki-67).@*CONCLUSION@#We demonstrated a relationship between emotional parameters, behavioral tendencies, CM parameters, and oncologic parameters in BC. Additional research is warranted to explore these associations and their relevance to clinical practice.

ABSTRACT

Resumo Este estudo transversal investigou a prevalência e os fatores associados ao diagnóstico de câncer de mama em estágio avançado entre 18.890 mulheres assistidas em hospital especializado da capital do Rio de Janeiro, Brasil, entre os anos 1999 e 2016. Utilizou-se regressão de Poisson com variância robusta para estimar razões de prevalência e respectivos intervalos de 95% de confiança. Apresentaram maiores prevalências de diagnóstico nessa condição mulheres com idade entre 20-39 e 40-49 anos, de raça/cor da pele preta e parda, que viviam sem companheiro(a), procedentes de outros municípios do estado do Rio de Janeiro, que tiveram o Sistema Único de Saúde como origem do encaminhamento e que foram diagnosticadas nos sexênios 1999-2004 e 2005-2010. Em contrapartida, mulheres com idade entre 60-69 e 70-99 anos, que cursaram algum nível de escolaridade, com histórico familiar de câncer e que chegaram ao hospital com diagnóstico e sem tratamento apresentaram menores prevalências de diagnóstico em estágio avançado. Esses resultados podem ser considerados no planejamento de ações de prevenção secundária, a fim de antecipar o diagnóstico de câncer de mama dos grupos mais vulneráveis e assim colaborar para a redução da prevalência do diagnóstico em estágio avançado.


Abstract This cross-sectional study investigated the prevalence and factors associated with advanced stage breast cancer diagnosis among 18,890 women assisted in a specialized hospital in the capital of Rio de Janeiro, Brazil, from 1999 to 2016. We used Poisson regression with robust variance to estimate prevalence ratios and respective 95% confidence intervals. The highest prevalence of diagnosis in this condition was in women aged 20-39 and 40-49 years, black and brown, living without a partner, from other cities of the state of Rio de Janeiro, who were referred by the Unified Health System and diagnosed in the 1999-2004 and 2005-2010 six-year periods. On the other hand, women aged 60-69 and 70-99 years, with some schooling level, with a family history of cancer and who arrived at the hospital with diagnosis and without treatment had lower prevalence of advanced stage breast cancer diagnosis. These results can be considered when planning secondary prevention actions to anticipate and, thus, collaborate to reduce the prevalence the breast cancer diagnosis in the most vulnerable groups.

ABSTRACT

Resumo Buscou-se identificar fatores que interferem na suspeita do câncer de mama (CM) pela atenção primária à saúde (APS) que impulsionam o encaminhamento para a atenção especializada (AE) nos municípios de São Paulo e Campinas. Foram entrevistadas 664 mulheres (353 paulistanas e 311 campineiras) diagnosticadas com CM, encaminhadas para AE pela APS. Utilizou-se a análise de regressão logística multinível para a identificação das associações entre a suspeita do CM pela APS, variáveis socioeconômicas e atenção ao câncer. Mostraram associação significativa: nível superior de escolaridade (RC = 0,59; IC 95% = 0,35-0,98); pagamento de consulta médica para atendimento relacionado ao câncer (RC = 0,59; IC 95% = 0,36-0,96), continuou atendimento na APS após início do tratamento na AE (RC = 0,62; IC 95% = 0,41-0,95); mama examinada na APS (ECM) antes do encaminhamento para a AE (RC = 1,61; IC 95% = 1,10-2,34) e primeira mamografia solicitada na APS (RC = 2,81; IC 95% = 1,95-4,00). A solicitação da mamografia e o ECM são ações que têm sido incorporadas na APS para a detecção precoce do CM nos municípios. Continuar o atendimento na APS e melhores condições socioeconômicas, como ter nível superior de escolaridade e capacidade de pagar por atendimento, reduzem a chance da suspeita.


Abstract We aimed to identify factors that interfere in breast cancer (BC) suspected cases detected in Primary Health Care (PHC) that drive the referral to Specialized Care (SC) São Paulo and Campinas, Brazil. We interviewed 664 women (353 from São Paulo and 311 from Campinas) diagnosed with BC, referred to SC from PHC. Multilevel logistic regression analysis was used to the identification of associations between BC suspected cases by PHC and the socioeconomic and cancer care variables. The following showed a significant association: higher schooling level (OR = 0.59; 95% CI = 0.35-0.98); medical visit payment for cancer-related care (OR = 0.59; 95% CI = 0.36-0.96), continued attendance at PHC after beginning treatment at SC (OR = 0.62; 95% CI = 0.41-0.95); breast examined in PHC before referral to SC (OR = 1.61; 95% CI = 1.10-2.34) and first mammography requested in PHC (ECM) (OR = 2.81; 95% CI = 1.95-4.00). The request for mammography and the clinical breast examination is incorporated into the PHC for the early detection of BC in the cities. Continuing the care at the PHC and better socioeconomic conditions, such as having a higher education level and capacity to pay for care, can reduce the likelihood of suspected cases.

ABSTRACT

INTRODUÇÃO: O câncer de mama é a neoplasia mais incidente entre mulheres, representando 24,5% entre todos os tipos de câncer nesta população. Além disto, representa a maior causa de morte neste grupo, respondendo por 15,5% dos óbitos entres todos os tipos de cânceres femininos. A faixa etária a partir de 50 anos é mais acometida, sendo relativamente raro antes dos 35 anos. As estratégias de detecção precoce são a base da Política Nacional de Atenção ao Câncer de Mama através do rastreamento e o diagnóstico precoce. Entretanto, parte significativa das mulheres brasileiras recebem o diagnóstico em estágios mais avançados da doença, principalmente nas regiões menos desenvolvidas do país. OBJETIVO: Avaliar os resultados e o impacto do programa de rastreamento e diagnóstico de câncer de mama, na Região de Saúde Juazeiro, Bahia (RSJ/BA), no período de 1998 a 2017. MATERIAL E MÉTODOS: foi realizado um estudo retrospectivo de serie temporal, avaliando as taxas de mortalidade por câncer de mama antes e após a implantação do serviço de diagnóstico do câncer na cidade de Juazeiro-BA, referência em diagnóstico de câncer na MSJ/BA, composta por dez cidades. As informações foram coletadas do Sistema de Informação de Mortalidade e Instituto Brasileiro de Geografia e Estatística, estabelecidas tendências temporais através do softwere JoinPoint e verificadas correlações entre distância e o IDH dos municípios através do teste de correlação de Pearson. Foram descritas características e perfil tumoral de todas as mulheres diagnosticadas no período de 2014 a 2018 através do softwere stata 11. RESULTADOS: As taxas de mortalidade aumentaram após implantação do serviço de diagnóstico, com tendência de crescimento da mortalidade, porém, com maior intensidade após a implantação do serviço. Houve correlação negativa entre as taxas de mortalidade e a distância das cidades e positiva com o IDH dos municípios. A maioria dos casos diagnosticados no serviço de referência (27%) ocorreu em 2018, na faixa etária de 50 a 69 anos (58%), CONCLUSÕES: A tendência de aumento da taxa mortalidade na RSJ/BA coincide com a implantação do serviço de rastreamento e diagnóstico precoce na cidade de Juazeiro ­ BA. Em todas as cidades atendidas pelo serviço, houve aumento das taxas de mortalidade, onde o acesso ao exame de MMG foi facilitado pela implantação do atendimento da unidade móvel de rastreamento e diagnóstico, principalmente nos municípios mais distantes, localizadas a mais de 200 km do centro de diagnóstico. As mulheres residentes em locais mais distantes dos serviços têm mais dificuldades para acessar o diagnóstico precoce e apresentam tumores maiores ao diagnóstico. Aprofundar o conhecimento e a compreensão das condições do acesso ao diagnóstico e tratamento é importante para melhorar as chances de prevenção e sobrevida das mulheres sertanejas.


INTRODUCTION: Breast cancer is the most frequent neoplasm among women, representing 24.5% of all types of cancer in this population. In addition, it represents the major cause of death in this group, accounting for 15.5% of deaths among all types of female cancers. The age group from 50 years is more affected, being relatively rare before the age of 35 years. Early detection strategies are the basis of the National Breast Cancer Care Policy through screening and early diagnosis. However, a significant part of Brazilian women are diagnosed at more advanced stages of the disease, especially in less developed regions of the country. OBJECTIVE: To evaluate the results and impact of the breast cancer screening and diagnosis program in the Juazeiro Health Region, Bahia (RSJ/BA), from 1998 to 2017. MATERIAL AND METHODS: a retrospective serial study was carried out temporal, evaluating breast cancer mortality rates before and after the implementation of the cancer diagnosis service in the city of Juazeiro-BA, reference in cancer diagnosis in MSJ/BA, composed of ten cities. The information was collected from the Mortality Information System and the Brazilian Institute of Geography and Statistics, temporal trends were established using the JoinPoint software and correlations between distance and the HDI of the municipalities were verified using Pearson's correlation test. Characteristics and tumor profile of all women diagnosed in the period from 2014 to 2018 were described using the software stata 11. RESULTS: Mortality rates increased after the implementation of the diagnostic service, with a tendency for mortality to increase, but with greater intensity after the implementation of the service. There was a negative correlation between mortality rates and distance from cities and a positive correlation with the HDI of municipalities. Most cases diagnosed in the referral service (27%) occurred in 2018, in the age group from 50 to 69 years (58%). CONCLUSIONS: The trend towards an increase in the mortality rate in RSJ/BA coincides with the implementation of a screening and early diagnosis service in the city of Juazeiro - BA. In all cities served by the service, there was an increase in mortality rates, where access to the MMG test was facilitated by the implementation of the mobile tracking and diagnosis unit, especially in the most distant municipalities, located more than 200 km from the center. of diagnosis. Women residing in locations further away from services have more difficulties in accessing early diagnosis and present larger tumors at diagnosis. Deepening the knowledge and understanding of the conditions of access to diagnosis and treatment is important to improve the chances of prevention and survival of sertaneja women.

ABSTRACT

The reasons for the recently observed increase in the incidence of breast cancer in the Indian population are not clearly understood, but thought to be largely explained by westernization of lifestyles and changes in reproductive behavior, which characterize exposure to hormones. Our aim is to review the reproductive risk factors and comorbidities and evaluate the association between molecular subtypes of breast cancer. A hospital-based analytical case-control study was conducted among the breast cancer cases with controls in a multispecialty teaching hospital for a period of one year. Totally, 130 subjects were recruited and an interview was conducted using a structured questionnaire to obtain demographic and risk factor data, including tissue marker status (ER, PR and HER-2) obtained from case files. Data were analyzed with SPSS-20 version. Results: The highest age group reported in this study was 51- 60 years which has a 3.8 times increased risk compared to other age and the age group of 31- 40 have a decrease risk of 0.33. In this study, the percentage of post menopause (68%) and mothers not breastfeeding (10%) was higher in cases compared to controls and a noted increase in the risk of breast cancer with odds ratio (OR) of 2.745 (p= <0.0001) and 9.08 (p=0.01) respectively. Duration of breastfeeding showed significantly (p=<0.0001)) moderate positive correlation (r=0.549, 0.457, 0.418 and 0.636) for luminal A, luminal B, HER+, and triple negative respectively. This study found that all the reproductive risk factors do not have correlation with a molecular subtype of breast cancer except breastfeeding. Post menopause and breastfeeding were common factors associated with all people and could be modifiable to prevent the occurrence of breast cancer through lifestyle change

ABSTRACT

This study aims to analyze inequalities in the incidence, mortality, and survival of the main types of cancer in women according to the Social Vulnerability Index (SVI). The study was conducted in Campinas, São Paulo State, Brazil, from 2010 to 2014, and used data from the Population-based Cancer Registry and the Mortality Information System. Incidence and mortality rates standardized by age and 5-year survival estimates were calculated according to the social vulnerability strata (SVS), based on the São Paulo Social Vulnerability Index. Three SVS were delimited, with SVS1 being the lowest level of vulnerability and SVS3 being the highest. Rate ratios and the concentration index were calculated. The significance level was 5%. Women in SVS1 had a higher risk of breast cancer (0.46; 95%CI: 0.41; 0.51), colorectal cancer (0.56; 95%CI: 0.47; 0.68), and thyroid cancer (0.32; 95%CI: 0.26; 0.40), whereas women from SVS3 had a higher risk of cervical cancer (2.32; 95%CI: 1.63; 3.29). Women from SVS1 had higher mortality rates for breast (0.69; 95%CI: 0.53; 0.88) and colorectal cancer (0.69; 95%CI: 0.59; 0.80) and women from SVS3 had higher rates for cervical (2.35; 95%CI: 1.57; 3.52) and stomach cancer (1.43; 95%CI: 1.06; 1.91). Women of highest social vulnerability had lower survival rates for all types of cancer. The observed inequalities differed according to the location of the cancer and the analyzed indicator. Inequalities between incidence, mortality, and survival tend to revert and the latter is always unfavorable to the segment of highest vulnerability, indicating the existence of inequality in access to early diagnosis and timely treatment.


O estudo teve como objetivo analisar desigualdades na incidência, mortalidade e sobrevida de câncer em mulheres de acordo com o Índice de Vulnerabilidade Social (IVS). O estudo foi realizado em Campinas, Estado de São Paulo, Brasil, no período de 2010 a 2014 e usou dados do Registro de Câncer de Base Populacional (RCBP) e do Sistema de Informação de Mortalidade (SIM). Foram calculadas as taxas de incidência e mortalidade padronizadas por idade e estimativas de sobrevida em cinco anos de acordo com estratos de vulnerabilidade social. Foram demarcados três estratos com base no IVS de São Paulo, onde o estrato 1 representava o nível de menor vulnerabilidade e o estrato 3 o de maior vulnerabilidade. Foram calculadas razões de taxas e índice de concentração, com nível de significância de 5%. Foram encontrados riscos mais elevados de câncer de mama (0,46; IC95%: 0,41; 0,51), colorretal (0,56; IC95%: 0,47; 0,68) e tireoide (0,32; IC95%: 0,26; 0,40) em mulheres do estrato 1 e de colo uterino em mulheres do estrato 3 (2,32; IC95%: 1,63; 3,29). Mulheres do estrato 1 tiveram taxas mais elevadas de câncer de mama (0,69; IC95%: 0,53; 0,88) e colorretal (0,69; IC95%: 0,59; 0,80), e mulheres do estrato 3 tiveram taxas mais elevadas de câncer do colo uterino (2,35; IC95%: 1,57; 3,52) e estômago (1,43; IC95%: 1,06; 1,91). Para todos os tipos de câncer, a sobrevida era mais baixa em mulheres do estrato de maior vulnerabilidade social. As desigualdades observadas mostraram diferenças de acordo com a localização do tumor e o indicador utilizado. Além disso, há uma tendência de inverter as desigualdades entre incidência, mortalidade e sobrevida, onde a sobrevida sempre é desfavorável para o estrato de maior vulnerabilidade, indicando a existência de desigualdades em acesso ao diagnóstico precoce e tratamento precoce.


El objetivo fue analizar las inequidades en la incidencia, mortalidad y supervivencia de los principales tipos de cáncer en mujeres, según el Índice de Vulnerabilidad Social (IVS). El estudio se llevó a cabo en Campinas, estado de São Paulo, Brasil, durante el período 2010-2014, y se usaron datos del Registro de Cáncer de Base Poblacional (RCBP) y el Sistema de Información de Mortalidad (SIM). Las tasas de incidencia y mortalidad estandarizadas por edad, así como las estimaciones de supervivencia durante cinco años, se calcularon según los estratos de vulnerabilidad social (SVS). Se delimitaron tres SVS, basados en el IVS de São Paulo, con SVS1 siendo el nivel más bajo de vulnerabilidad y SVS3 siendo el nivel más alto de vulnerabilidad. Se calcularon los cocientes de tasas y el índice de concentración. El nivel de significancia fue 5%. Se encontró un riesgo más alto de cáncer de la mama (0,46; IC95%: 0,41; 0,51), colorrectal (0,56; IC95%: 0,47; 0,68), y tiroides (0,32; IC95%: 0,26; 0,40) en mujeres de SVS1, y cáncer cervical en mujeres de SVS3 (2,32; IC95%: 1,63; 3,29). Respecto a la mortalidad, las mujeres de SVS1 tuvieron tasas más altas en cáncer de la mama (0,69; IC95%: 0,53; 0,88) y colorrectal (0,69; IC95%: 0,59; 0,80) y las mujeres de SVS3 tuvieron tasas más altas en cáncer cervical (2,35; IC95%: 1,57; 3,52) y estómago (1,43; IC95%: 1,06; 1,91). Para todos los tipos de cáncer, las tasas de supervivencia fueron más bajas en mujeres del estrato social con más alta vulnerabilidad social. Las inequidades sociales observadas difirieron según la localización del cáncer y el indicador analizado, y no hubo una tendencia para revertir las inequidades entre incidencia, mortalidad y supervivencia, las últimas siempre fueron desfavorables para el segmento de más alta vulnerabilidad, indicando la existencia de desigualdad en el acceso a un diagnóstico temprano y un tratamiento oportuno.

ABSTRACT

Introducción: El cáncer de mama es el cáncer más frecuente en las mujeres colombianas y más de la mitad de la incidencia la aportan las adultas mayores de 60 años. El objetivo de este estudio fue caracterizar clínicamente a un grupo de pacientes ≥ 65 años, con diagnóstico de cáncer de mama primario. Metodología: Estudio descriptivo de 188 pacientes con edad ≥ 65 años, con cáncer de mama primario, atendidas en la Fundación Colombiana de Cancerología ­ Clínica Vida, entre enero de 2017 y diciembre de 2018. Se realizó un análisis descriptivo de datos sociodemográficos, comorbilidades, características de la enfermedad y tratamiento. Resultados: La población estudiada (188) presentó una edad promedio de 73 años y en el 79.8% de ellas se reportó al menos una comorbilidad. El 76.6% tuvo enfermedad con receptor hormonal positivo. El manejo primario con cirugía se hizo en el 58.5% de las pacientes, y la mayoría fueron procedimientos conservadores de la mama (70.9%). Conclusión: Las mujeres adultas mayores tienen características del cáncer de mama que pueden diferir de las pacientes jóvenes e influir en el tratamiento que se ofrece, impactando en su pronóstico oncológico, en el pronóstico de sus comorbilidades y en la calidad de vida.


Introduction: Breast cancer is the most frequent cancer in Colombian women and more than half of the incidence is contributed by adults over 60 years of age. The objective of this study was to clinically characterize a group of patients ≥ 65 years of age, diagnosed with primary breast cancer. Methodology: Descriptive study of 188 patients aged ≥ 65 years, with primary breast cancer, treated at the Colombian Cancer Foundation - Clínica Vida, between January 2017 and December 2018. A descriptive analysis of sociodemographic data, comorbidities, characteristics of the disease and treatment. Results: The studied population (188) had an average age of 73 years and in 79.8% of them at least one comorbidity was reported. 76.6% had hormone receptor positive disease. The primary manage-ment with surgery was done in 58.5% of the patients, and the majority were breast-conserving proce-dures (70.9%). Conclusion: Older women have characteristics of breast cancer that may differ from young pa-tients. This may influence the treatment offered, impacting on their oncological prognosis, on the prognosis of their comorbidities and on the quality of life.

El 95,5% deseaban realizar la medicatura rural. La medida de prevención menos conocida en un 85.6% fue la edad requerida para iniciar el screening con mamografía. El factor de riesgo menos conocido fue el alcohol 39.6%, mientras que un 85.6% consideró al factor genético-hereditario como elemento pre-dominante para el desarrollo de cáncer de mama. Conclusión: El nivel de conocimiento de los participantes del estudio se encontró en un nivel suficiente. Es necesario reforzar aspectos como el reconocimiento de signos y síntomas, e identificación de factores de riesgo modificables relacionados


Introduction: In 2020, according to Globocan data, Ecuador registered 3,563 new cases of breast cancer, being the most prevalent diagnosis in the female population, all strategies' in the fight against this pathology will be great value. The objective of the study is to determine the level of knowledge of the rotating medical interns about the prevention and timely detection of breast cancer. Methodology: Descriptive cross-sectional study in 111 rotating medical interns at Hospital Teodoro Maldonado. A questionnaire with 15 closed multiple-choice questions was used, recording socio-demographic characteristics and questions related to knowledge in health promotion, identification of signs, symptoms, risk factors and screening with mammography. Given the context of the COVID19 health emergency, the questionnaire was virtual. Results: The median age was between 25 and 30 years, 62.2% were women. 95.5% wanted to take rural medicine. The least known prevention measure in 85.6% was the age required to start screening with mammography. The least known risk factor was the consumption of alcohol 39.6%, while 85.6% considered the genetic-hereditary factor as the predominant element for development of breast can-cer. Conclusion: The level of knowledge of the study participants was found to be at a sufficient level. It is necessary to reinforce aspects such as the recognition of signs and symptoms, and the identifica-tion of related modifiable risk factors.
