Nursing care regarding the psycho-emotional aspects of women submitted to mastectomy / Assistência de enfermagem frente aos aspectos psicoemocionais de mulheres mastectomizadas

Breast cancer, or breast neoplasm, is one of the most frequent types of cancer, and one of the most prevalent among women. The diagnosis and specific treatments, such as mastectomy surgery, lead women to experience different feelings, with the most predominant negative thoughts. In this way, the objective of this study is to describe the importance of nursing care in the face of the psycho-emotional aspects of women after mastectomy. This is an integrative literature review study, developed in electronic Medline and Lilacs databases. The following terms were used: Breast neoplasm; Nursing; Emotions; Mastectomy. A total of 2,314 articles were found, of which eight were selected. The results and discussions were divided into two thematic axes: The first deals with the emotions of women after mastectomy, whose feelings arising from the diagnosis of the disease start to affect different areas, such as personality, sexuality, family, and social relationships. Furthermore, the second deals with nursing care after mastectomy, which must be conducted integrally, aiming at restoring physical and emotional health. Nursing is the vehicle capable of planning and collaborating with these women, promoting humanized treatment and assistance, oriented and aimed at a better quality of life, and stimulating self-help, self-esteem, and acceptance of their body.

O câncer de mama ou neoplasia da mama, é um dos tipos de cânceres mais frequentes, e um dos mais prevalentes entre as mulheres. O diagnóstico e determinados tratamentos, como a cirurgia de mastectomia, levam as mulheres a vivenciarem diferentes sentimentos, sendo os pensamentos negativos os mais predominantes. Desta maneira, o objetivo deste estudo é descrever a importância da assistência do enfermeiro frente aos aspectos psicoemocionais de mulheres mastectomizadas. Trata-se de um estudo de revisão integrativa da literatura, desenvolvida nas bases eletrônicas de dados Medline e Lilacs. Foram utilizados os seguintes descritores: Neoplasias da mama; Enfermagem; Emoções; Mastectomia. Foram encontrados 2314 artigos, dos quais foram selecionados oito. Os resultados e discussões foram divididos em dois eixos temáticos: O primeiro trata das emoções das mulheres mastectomizadas, cujos sentimentos advindos com o diagnóstico da doença passam a afetar diferentes aspectos psicoemocionais, como personalidade, sexualidade, família e relações sociais. E o segundo trata da assistência de enfermagem após a mastectomia, a qual deve se dar de maneira integral, visando tanto o restabelecimento da saúde física quanto emocional. A enfermagem pode desempenhar um cuidado diferenciado e voltado para as necessidades psicoemocionais das mulheres, promovendo tratamento e assistência humanizados, orientados e voltados a uma melhor qualidade de vida, e com o fim de estimular a autoajuda, a autoestima e a aceitação de seu corpo.

Incidence of radiodermatitis and factors associated with its severity in women with breast cancer: a cohort study

Abstract Background: One of the main adverse reactions of adjuvant radiotherapy for breast cancer is radiodermatitis. Objective: To assess the incidence of radiodermatitis in women with breast cancer, identify factors associated with its severity and determine the time at which this event occurs. Methods: Prospective cohort study in 113 women with breast cancer who were evaluated before radiotherapy and at every fifth session until the end of treatment. Logistic regression and Cox proportional regression model were used for the assessment of risk factors; P values < 0.05 were considered significant. Results: The incidence rate of radiodermatitis was 98.2% and it was demonstrated that for each additional point of the Body Mass Index (BMI), the chance of occurrence of grades II to IV radiodermatitis increases by 14% (OR = 1.14 [95% CI 1.04-1.26]; p = 0.004) and statin use increases the risk of more severe skin lesions by four-fold (OR = 4.27 [95% CI 1.11-16.42]; p = 0.035). The exclusive use of hydrogel for skin hydration was an independent factor in delaying the onset of radiodermatitis (HR = 0.55 [95% CI 0.36-0.82]; p = 0.004). Study limitations: The main limitation of this study was its external validity. The identified factors should be considered for services and populations similar to those in this study. Conclusions: There was a high incidence of radiodermatitis and its severity was related to higher BMI, statin use; there was a protective effect of hydrogel use.

Triple negative breast cancer:a study based on histological and immunohistochemical classification / 临床与实验病理学杂志

Purpose To evaluate the classification criteria of triple negative breast cancer(TNBC)based on histomorphol-ogy and immunohistochemistry(IHC),and to provide theoreti-cal basis for the classification and treatment of TNBCs.Methods TNBC subtyping was performed according to the histomorphologi-cal characteristics and the expression of immune markers AR,CD8 and FOXC1,and the clinicopathological features and prog-nostic differences were compared.Results Among 93 cases of TNBC,there were 23 cases(24.7％)of luminal androgen re-ceptor subtypes,24 cases(25.8％)of immunomodulatory type,39 cases(42.0％)of basal immunosuppressive type,and 7 ca-ses(7.5％)of mesenchymal type.There were significant differ-ences in the clinicopathological features of subtypes,including pT stage(P=0.030),histological grade(P＜0.001),intersti-tial lymphocyte infiltration pattern(P＜0.001),expression of PD-L1(P＜0.001),and HER2-low(P=0.024).There was no significant difference in disease-free survival among the sub-types(P＞0.05).Univariate survival analysis showed there was significant difference in disease-free survival among the subtypes at pT1 stage(P=0.011),and other clinicopathological features were not independent prognostic factors.Conclusion The clini-copathological characteristics of TNBC subtypes are different,which are expected to be an alternative choice for complex gene expression profile analysis and to provide theoretical basis for subtypic therapy and targeted therapy.

Correlation between tumor abnormal protein level and molecular typing and clinicopathological characteristics in breast cancer / 临床与实验病理学杂志

Purpose To investigate the relationship be-tween the level of tumor abnormal protein(TAP)and the molec-ular subtypes and clinicopathological features of breast cancer,and to analyze the value of TAP in breast cancer screening,di-agnosis and prognosis prediction.Methods The clinical data of 357 breast cancer patients were collected,and the elbow venous blood was collected to detect the TAP condensate area.Immuno-histochemical(IHC)EnVision two-step method was used to de-tect the expression of AR,ER,PR,HER2,p53 and Ki67,and FISH to detect HER2 gene.The relationship between TAP ex-pression and clinicopathological features,molecular subtypes and clinical stages of breast cancer was analyzed,and the rele-vant literature was reviewed.Results Among 357 breast cancer patients,9 cases(2.52％)were TAP negative,36 cases(10.08％)were weakly positive,312 cases(87.40％)were strongly positive,and the positive rate of TAP was 97.48％.AR was positive in 321 cases and negative in 36 cases,ER was pos-itive in 256 cases and negative in 101 cases,PR was positive in 214 cases and negative in 143 cases,HER2 was strongly posi-tive in 98 cases,weakly positive in 214 cases and negative in 45 cases,p53 was positive in 146 cases and negative in 211 cases,Ki67 index was ≥20％in 276 cases and＜20％in 81 case.A total of 155 cases of IHC HER2(2+)breast cancer were tested by FISH:140 cases were negative and 15 cases were positive.The expression level of TAP in patients of ≥50 years old expres-sionas significantly higher than that in patients of＜50 years old(P＜0.05).The expression level of TAP in patients with high Ki67 proliferation index was significantly higher than that in pa-tients with low Ki67 proliferation index(P＜0.05).There was a significant difference in TAP expression between patients with different molecular subtypes(P＜0.05).Tap expression was higher in triple-negative breast cancer patients than in non-tri-ple-negative breast cancer patients(P＜0.05),and it was high-er in Luminal B breast cancer patients than in non-Luminal B breast cancer patients(P＜0.05).There was a significant difference in TAP expression between patients with different clin-ical stages(P＜0.05),and TAP expression level was positively correlated with clinical stage in breast cancer.Conclusion TAP detection can improve the diagnostic accuracy of breast cancer,and has a certain correlation with the survival rate and prognosis of breast cancer patients.

Malignant phyllodes tumor of the breast in ayoung patient ­ case report

Phyllodes tumor (PT) is an uncommon form of breast tumor. It occurs most commonly in women aged 35 to 65 years. The benign form represents about 85­90% of cases and only 10­15% of PTs are malignant. Clinically and radiologically, malignant phyllodes tumor (MPT) presents as regular, well-delimited, mobile nodules that are difficult to distinguish from fibroadenomas of the breast. The most important differential diagnoses of MPT include fibroadenoma, metaplastic carcinoma, and sarcoma. The prognosis of MPT exhibits a higher frequency of local recurrence and metastatic rate with larger tumors and inadequate surgical margins. The case presented here refers to a 24-year-old female patient, with a vast tumor in the right breast, with rapid and progressive growth, associated to local pain, and histological diagnosis of MPT. Surgery was the initial treatment, followed by adjuvant chemotherapy and radiotherapy. The purpose of this article was to report an atypical case of MPT of the breast in a very young woman as well as to make a brief literature review on this infrequent and dangerous disease. (AU)

Association between obesity and triple-negative breast cancer: a systematic qualitative review

Introduction: The relation between obesity and triple-negative breast cancer (TNBC) is not totally elucidated. TNBC represents a heterogeneous group of aggressive growth neoplasms. The concepts related to the development of hormone receptorpositive tumors cannot be directly extended to this group. To evaluate the association between obesity and TNBC, considering as primary outcome the assessment of the incidence of this tumor subtype in this population and as secondary outcomes the specific pathophysiology, prognosis, and treatment in this context. Methods: This was a systematic review following the Preferred Reporting Items for Systematic reviews and Meta-Analyses ­ PRISMA statement. PubMed/MEDLINE and Cochrane were the databases used as primary paper sources. Inclusion according to titles and abstracts allowed a secondary selection by reference list revision. The final full-text review was done on the most opportune studies identified. Results: A total of 52 articles were included. Epidemiology: A higher frequency of obesity among TNBC patients compared to other subtypes and TNBC in obese women was observed in the literature. It is uncertain whether premenopausal status is an aggravating factor. Pathophysiology: Several studies identified the production of different factors by obese adipose tissue and their regulation of genes related to the expression of stem-like cell properties, mainly leptin, IL-6, and IL-8. Prognosis: Most studies pointed out that disease-free survival and overall survival are independent of body mass index. Treatment: Weight reduction showed no significant power in improving prognosis but may favor primary incidence prevention. Drugs based on obesity-related pathways are still in research, and various potential targets were raised. Conclusions: Obesity is a risk factor for TNBC. Obese-related inflammatory cytokines may contribute to tumor development. Once TNBC is established, the prognosis does not differ according to initial body mass index changes. No target drug for obesity-related tumorigenic pathways is currently available for clinical use. (AU)

Neuromuscular bandage for the prevention of post-mastectomy seroma: a clinical trial protocol

Introduction: Seroma is the most common early complication after breast cancer surgery and is associated with other complications and adjuvant therapy delays. A potential hypothesis for its prevention is the obliteration of dead space between tissues, which can be achieved by external compression. To assess whether the use of a neuromuscular bandage employing the compressive technique during the first postoperative week is effective in preventing seroma. Methods: This study comprises a two-arm randomized superiority clinical trial to evaluate the following as primary outcomes: seroma incidence, volume and duration using a suction drain and bandage safety and satisfaction as secondary outcomes. Women aged ≥18 years submitted to a mastectomy as breast cancer treatment will be included, while women submitted to bilateral mastectomies, immediate breast reconstruction or surgical flap rotation closure, who present hematomas or surgical wound infections at the time of recruitment or autoimmune diseases that lead to skin lesions and/ or allergy to tape, as well as those exhibit difficulties in understanding the study will be excluded. Randomization will be performed by lots at study enrollment. Coded envelopes will be available for intervention or control group allocations. Patients allocated in the intervention group will be submitted to the bandage application for seven days. All patients will use a suction drain according to the institution's routine. Ethics and disclosure: This study was approved by the Brazilian National Cancer Institute, Research Ethics Committee under no. 2,774,824 and it is registered in the ClinicalTrials.gov (NCT04471142).

Assessment of the relationship between metabolic syndrome and breast cancer

Introduction: Metabolic syndrome (MS) affects approximately 30% of women aged over 50 years. It is known to have a direct relationship with carcinogenesis and, therefore, with breast neoplasia. Methods: Retrospective longitudinal observational cohort study carried out at the Gynecology and Obstetrics Service of the São Paulo State Public Servant Hospital. The rates of local recurrence, distant metastases and overall survival of patients with malignant breast neoplasia in each group were evaluated. Results: Between 2017 and 2020, 375 patients underwent surgical treatment for breast cancer, of which 335 were eligible for the study, with an average age of 63.4 years old. MS is present in 32.5% of patients. Regarding the prognostic factor, patients with MS have a very similar distribution. The molecular profile in patients with MS is 39.4% of Luminal A patients, while in those without MS it is 42.5% of Luminal B. Regarding clinical staging, patients with MS have initial clinical stage I and IIA in 54 .1% of cases, while patients without MS present an initial clinical stage in 65% of cases. The average overall survival of the sample was 37.3 years, with a CI of 1.1 years; disease-free survival was 35.9 years, with CI 1.2 years; and invasive disease-free survival was 36.9 years, with CI 1.3 years. Conclusions: The presence of MS at diagnosis does not worsen survival. (AU)

Survivin expression as a prognostic marker for breast cancer

SUMMARY OBJECTIVE: Due to the speed of development observed in breast cancer, several studies aimed at discovering new biomarkers have been carried out in order to arrive at an early diagnosis. As survivin plays a fundamental role in the evasion of apoptosis in tumor cells, the aim of this study was to verify the expression profile of the survivin gene in paraffin-embedded breast tumor samples and associate it with the clinical characteristics of the patients. METHODS: This is a cross-sectional study, for which 100 tumor samples were obtained from cancer patients treated throughout the year 2019 at Instituto de Mama do Cariri (Juazeiro do Norte, in the state of Ceará). This study included women over 30 years old who had confirmed breast cancer through anatomopathological examination but excluded those with non-neoplastic breast comorbidities, other neoplasms, or chronic diseases. Survivin gene expression was assessed by quantitative polymerase chain reaction. RESULTS: The expression of survivin is associated with the lack of expression of estrogen (p=0.027) and progesterone (p>0.0005) receptors. It means that survivin expression is higher in patients in which labeling was absent for estrogen receptor and progesterone receptor. CONCLUSION: Our data reinforce that survivin expression is higher in estrogen receptor-patients, thus representing an additional prognostic tool.

Analysis of Watson for oncology and clinicians� treatment recommendations for patients with breast cancer in Korea: A single center experience

Background: Various clinical applications have been attempted using artificial intelligence (AI) clinical decision support system (CDSS), and it has become a starting point for personalized cancer treatment. We aimed to identify the degree of agreement between the AI?CDSS, Watson for Oncology (WFO), and the clinician in treatment recommendations for Korean breast cancer patients and to provide guidelines for future improvement. Methods: One hundred and eighty?three breast cancer patients who underwent treatment at the Pusan National University Hospital between January 1, 2016 and May 31, 2017 were enrolled in this study. The concordance between WFO抯 and clinicians� treatment recommendations were examined according to various factors. Results: WFO gave the same treatment option recommendations as clinicians in 74 (40.4%) of the cases. According to the logistic regression, the difference in recommendation concordance between stage I and stage III was statistically significant (P = 0.004), and there was no difference among other factors. Conclusion: The concordance of treatment recommendations was low overall. However, this is largely attributable to the differences of medical insurance system and healthcare environment between the United States and Korea. In the future, region?specific features should be considered or reflected during the development of AI?CDSS.

Predictive value of 18F-FDG PET/CT radiomic fusion features combined with XGBoost model for HER2 expression status in breast cancer / 中华核医学与分子影像杂志

Objective:To evaluate the value of radiomic fusion features combined with extreme gradient boosting (XGBoost) machine learning models based on 18F-FDG PET/CT images in the prediction of human epidermal growth factor receptor 2 (HER2) expression status in breast cancer. Methods:18F-FDG PET/CT images of 210 patients with primary breast cancer (all females; age 52(46, 60) years; 95 HER2-positive and 115 HER2-negative) in Tianjin Medical University Cancer Institute and Hospital between January 2012 and December 2019 were retrospectively analyzed. About 70% of the HER2-positive and HER2-negative groups were randomly selected using Python 3.7.1 software as a training set ( n=147; 67 HER2-positive and 80 HER2-negative, age: 52(46, 60) years vs 55(45, 62) years) and 30% as a test set ( n=63; 28 HER2-positive and 35 HER2-negative, age: 54(43, 65) years vs 52(45, 61) years). After tumor segmentation on CT and PET images being finished, CT and PET radiomic features were extracted respectively. PET/CT fusion features (including PET/CT splicing features and PET/CT mean features) were obtained through post-processing. The support vector machine (SVM) model and XGBoost model were established. The selected features were input to predict the expression status of HER2 in primary breast cancer lesions, and the prediction efficiency of the model was evaluated by ROC curve. The Delong test was used to compare the predictive effectiveness of different models and radiomic features, and the calibration curve of the machine learning model with the highest prediction efficiency was plotted. Results:Compared with SVM model, XGBoost model had better prediction performance ( z values: 2.26-3.54, P values: 0.016-0.040) when four kinds of radiomic features (CT features, PET features, PET/CT splicing features and PET/CT mean features) were input. ROC curve analysis showed that PET/CT mean features with XGBoost machine learning model had the best performance in predicting the expression status of HER2, and the maximum AUC was 0.83 (95% CI: 0.73-0.93), which was superior to CT features (0.75(95% CI: 0.63-0.88); z=3.57, P=0.027), PET features (0.73(95% CI: 0.60-0.86); z=2.64, P=0.034) and PET/CT splicing features (0.74(95% CI: 0.60-0.87); z=2.49, P=0.037). Conclusion:XGBoost machine learning model based on PET/CT radiomics fusion features is expected to predict HER2 expression status in patients with breast cancer.

Study on the efficacy and influencing factors of pyrotinib in treatment of patients with human epidermal growth factor receptor 2-positive metastatic breast cancer / 肿瘤研究与临床

Objective:To evaluate the efficacy of oral pyrotinib in treatment of patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer in the real world, and to explore its influencing factors.Methods:The clinical data of 148 patients with HER2-positive metastatic breast cancer treated with oral pyrrolitinib in Shanxi Cancer Hospital from September 2018 to December 2020 were retrospectively analyzed. The efficacy was evaluated according to the efficacy evaluation criteria for solid tumors, version 1.1, and the adverse effects were graded according to the National Cancer Institute common terminology criteria of adverse effects, version 4.0. The Kaplan-Meier method was used to draw progression-free survival (PFS) curves, the patients were stratified by different clinical characteristics, and log-rank test was used for univariate analysis of PFS; the multivariate analysis of PFS was performed using Cox proportional hazards model.Results:The objective response rate (ORR) of 148 patients was 71.6% (106/148), and the disease control rate (DCR) was 89.2% (132/148). The overall median PFS time was 11.0 months (95% CI 10.1-11.9 months), and the median PFS of 19 patients with brain metastases was 10.0 months (95% CI 7.4-12.6 months). The differences in PFS between patients stratified by disease-free interval (DFI), the number of metastatic site and Eastern Cooperative Oncology Group (ECOG) score were statistically significant (all P < 0.05), but the difference in PFS between patients with negative and positive hormone receptor was not statistically significant ( P > 0.05). Multivariate Cox regression analysis showed that DFI (>1 year vs. ≤1 year: HR = 5.254, 95% CI 0.728-37.933, P = 0.046) and ECOG score (≥2 points vs. 0-1 point: HR = 2.454, 95% CI 1.261-4.788, P = 0.008) were independent influencing factors of PFS. The most common ≥grade 3 adverse effects were diarrhea (31 cases, 20.9%) and hand-foot syndrome (38 cases, 25.8%). Conclusions:The pyrotinib has definite efficacy and good safety in the treatment of HER2-positive metastatic breast cancer in the real world, especially for patients with DFI > 1 year and ECOG score 0-1 point, the efficacy and safety are particularly good.

Dance therapy and free dance with a focus on the psychological aspects of patients in adjuvant treatment of breast cancer - study protocol for randomized clinical trial

Abstract Aim: To propose a dance therapy and free dance protocol for women undergoing adjuvant treatment of breast cancer and to compare its effectiveness with the control group and the healthy group. Method: Protocol for a 12-week randomized clinical trial with a frequency of 2 times at progressive intensity, in which the participants will be allocated into 4 groups: (a) dance therapy intervention; (b) free dance intervention; (c) control group and (d) healthy group. Information related to personal and clinical characteristics as well as psychological aspects will be collected. The primary outcome will be analyzed through depressive symptoms while secondary outcomes include the variables: body image, anxiety, mood, perceived stress, and optimism. Assessments will be carried out in the pre-intervention period (baseline) and after 12 weeks of intervention in all groups. Discussion: As a hypothesis, there are improvements in psychological aspects after dance therapy interventions and free dance, reaching the level of healthy women, given the benefits of that protocol.

Variabilidade espacial intraurbana da mortalidade por câncer de mama e do colo do útero no município de São Paulo: análise dos fatores associados / Intra-urban spatial variability of breast and cervical cancer mortality in the city of São Paulo: analysis of associated factors

RESUMO Objetivo: Identificar a variabilidade espacial da mortalidade por câncer de mama e colo do útero e avaliar fatores associados à mortalidade por esses cânceres no município de São Paulo. Métodos: Entre 2009 e 2016 foram registrados, no Sistema de Informações sobre Mortalidade, 10.124 óbitos por câncer de mama e 2.116 óbitos por câncer do colo do útero em mulheres com 20 anos e mais. Os registros foram geocodificados por endereço de residência e agregados segundo território adstrito. Foram realizadas modelagens de regressão espacial utilizando-se a abordagem bayesiana com estrutura de Besag-York-Mollié para verificar a associação dos óbitos com indicadores selecionados. Resultados: As taxas de mortalidade por esses cânceres apresentaram padrões espaciais inversos. As variáveis associadas à mortalidade por câncer de mama foram: tempo de deslocamento para o trabalho entre uma e duas horas (risco relativo — RR 0,97; intervalo de credibilidade — IC95% 0,93-1,00); mulheres responsáveis pelo domicílio (RR 0,97; IC95% 0,94-0,99) e óbitos por câncer de mama ocorridos em estabelecimentos privados (RR 1,04; IC95% 1,00-1,07). À mortalidade por câncer do colo do útero, estiveram associados: tempo de deslocamento para o trabalho entre meia e uma hora (RR 0,92; IC95% 0,87-0,98); rendimento domiciliar até três salários-mínimos (RR 1,27; IC95% 1,18-1,37); e razão de menores de um ano em relação à população feminina de 15 a 49 anos (RR 1,09; IC95% 1,01-1,18). Conclusão: Foram calculados os RR preditos para a mortalidade por esses cânceres, que estiveram associados às condições socioeconômicas das áreas de abrangência.

ABSTRACT Objective: To identify spatial variability of mortality from breast and cervical cancer and to assess factors associated in the city of São Paulo. Methods: Between 2009 and 2016, 10,124 deaths from breast cancer and 2,116 deaths from cervical cancer were recorded in the Mortality Information System among women aged 20 years and over. The records were geocoded by address of residence and grouped according to Primary Health Care coverage areas. A spatial regression modeling was put together using the Bayesian approach with a Besag-York-Mollié structure to verify the association of deaths with selected indicators. Results: Mortality rates from these types of cancer showed inverse spatial patterns. These variables were associated with breast cancer mortality: travel time between one and two hours to work (RR - relative risk: 0.97; 95%CI - credible interval: 0.93-1.00); women being the head of the household (RR 0.97; 95%CI 0.94-0.99) and deaths from breast cancer in private health institutions (RR 1.04; 95%CI 1.00-1.07). The following variables were associated with mortality from cervical cancer: travel time to work between half an hour and one hour (RR 0.92; 95%CI 0.87-0.98); per capita household income of up to 3 minimum wages (RR 1.27; 95%CI 1.18-1.37) and ratio of children under one year of age related to the female population aged 15 to 49 years (RR 1.09; 95%CI 1.01-1.18). Conclusion: The predicted RR for mortality from these cancers were calculated and associated with the socioeconomic conditions of the areas covered.

Evaluation of clinical, pathological and epidemiological profile of patients with breast cancer in the microregion of Lavras ­ MG

Breast cancer is associated with high frequency and mortality in Brazilian women. There have been limited studies portraying the characteristics of breast cancer cases in the countryside of the state of Minas Gerais for a long period of time, a fact that will allow us to better understand the epidemiology of these tumors. This descriptive study aims to analyze the epidemiology and clinical features of patients with breast cancer treated at a public health service facility in Lavras, MG. Methods: This is a transversal study with 299 women diagnosed with breast cancer between 2002 and 2022, based on data collection from medical records and subsequent descriptive analysis. Results: There were a total of 317 cases, and 299 were eligible for the study. The mean age at diagnosis was 54.2 years, and 36.1% of the patients were under 50 years old at diagnosis. Positive family history was found in 17.0% of the patients. The diagnosis was made by clinical alteration detected on physical examination in 71.5% of cases, and lump was the most frequent type of lesion (89.0%). Invasive carcinoma was 93.1% of the cases, and the mean tumor size was 28.6 mm. The average time between first medical appointment and diagnosis was 63.2 days, and between diagnosis and beginning of treatment was 39.6 days. Conclusions: This study showed that a significant number of cases occurred in women outside the recommended age for screening in Brazil. Diagnosis was predominantly performed by clinical examination, with delays in obtaining the histological diagnosis, and the stage at diagnosis was high, and these facts were associated with the health system limitations (AU)

Exposición a material particulado y su relación con el cáncer de mama. Mecanismos fisiopatológicos / Exposure to particulate matter and its association to breast cancer. Pathophysiological mechanisms

Introducción. El cáncer de mama es el tipo de cáncer que genera más muertes en mujeres en el mundo. Aunque se reconoce el aporte de factores genéticos, hormonales y de estilos de vida como sus principales causas, las hipótesis que señalan que la contaminación del ambiente juega un papel importante en su desarrollo, han tomado mucha fuerza en los últimos años. Estas hipótesis surgen debido a que el aumento en la incidencia del cáncer de mama coincide con procesos de industrialización, además de mayor presencia en regiones urbanas y con altos niveles de contaminación. El objetivo de este artículo fue consolidar información sobre los mecanismos fisiopatológicos que puedan explicar la relación entre cáncer de mama y la contaminación por material particulado. Metodología. Se realizó una búsqueda de literatura en PubMed, Google Académico y Epistemonikos para documentos publicados sobre el tema desde enero de 2016 hasta el 3 de agosto de 2022. Resultados. Se encontró que algunos de los mecanismos que podrían explicar dicha relación incluyen: alteraciones endocrinas que favorecen cambios hormonales, induciendo el crecimiento mamario; cambios en las características histológicas del tejido normal, como involución reducida de unidades lobulares ductales terminales; formación de aductos de hidrocarburos aromáticos policíclicos-ácido desoxirribonucleico (HAP-ADN), con mutación específica del gen TP53; activación de la proliferación en la línea celular MCF-7; y, alteraciones en la metilación del ADN. Conclusión. Si bien órganos distales como la mama no son la primera entrada de los contaminantes ambientales al cuerpo, estos sí pueden verse afectados tras la exposición a largo plazo, a través de diferentes mecanismos de disrupción endocrina y daño al ADN principalmente

Breast cancer is the type of cancer that causes the most deaths in women worldwide. Although the contribution of genetic, hormonal and lifestyle factors are recognized as its main causes, the hypotheses that indicate that environmental pollution has an important role in its development have taken on great strength during the last years. These hypotheses are based on the increase in the incidence of breast cancer that coincides with industrialization processes, in addition to its greater presence in urban regions with high levels of pollution. The aim of this study was to consolidate information on the pathophysiological mechanisms that can explain the relationship between breast cancer and air pollution by particulate matter. Methodology. A literature search was carried out in PubMed, Google Scholar and Epistemonikos for documents published on this topic from January 2016 until August 3rd 2022. Results. Some of the mechanisms that could explain this association include endocrine alterations that favor hormonal changes, inducing breast growth; changes in the histological characteristics of normal tissue such as reduced involution of terminal duct lobular units; formation of polycyclic aromatic hydrocarbons-deoxyribonucleic acid (PAH-DNA) adducts, with specific mutation of the TP53 gene; an increase in cell proliferation in the MCF-7 cell line; and alterations in DNA methylation. Conclusion. Although distal organs such as the breast are not the entry site of environmental pollutants into the body, they can be affected after prolonged exposure, mainly through different mechanisms of endocrine disruption and DNA damage

Free dance randomized clinical trial for women undergoing breast cancer surgery / Ensaio clínico aleatório de dança gratuita para mulheres submetidas a cirurgia de câncer da mama / Ensayo clínico aleatorizado de danza gratuita para mujeres sometidas a cirugía de cáncer de mama

Objective: to analyze the effect of a free dance protocol (pre and post 12- week intervention) on depressive symptoms, body image and sexual function in women undergoing breast cancer surgery. Methods: a randomized clinical trial, composed of 24 women undergoing surgery after the diagnosis of breast cancer, who were randomized into two groups: Free dance Intervention Group and Control Group. The free dance group received the intervention twice a week, 60 minutes per session, for 12 weeks. The control group maintained their routine activities during the 12 weeks. All participants were evaluated before and after the 12 weeks of intervention. Outcomes evaluated were depressive symptoms (Beck Depression Questionnaire - BDI), body image (Body Image after Breast Cancer questionnaire) and sexual function (Female Sexual Function Index questionnaire). Results: Body image showed a significant intragroup difference in free dance in the vulnerability domain (p=0.031), significant intergroup difference in the limitation domain (p=0.045) and concern with the body (p=0.035). Sexual function showed a significant intragroup difference in free dance in the desired domain (p=0.031) and a significant intragroup difference in the control group in the lubrication domain (p=0.021), however in a negative way. No differences were found for depressive symptoms. Conclusions: The practice of free dancing showed a positive effect, even if small, on body image and a negative effect on sexual function in women undergoing breast cancer surgery.

Role of intrathecal chemotherapy in the management of meningeal carcinomatosis in patients with breast cancer

ABSTRACT Objective To evaluate whether intrathecal chemotherapy improves clinical outcomes in patients with meningeal carcinomatosis. Methods This retrospective cohort study included consecutive patients with breast cancer diagnosed with meningeal carcinomatosis. Clinical and treatment data were collected from the patients' medical charts. The primary outcome was overall survival, and the secondary outcomes were time to neurological deterioration and reporting of clinical benefit. Logistic regression and Cox proportional hazard models adjusted for potential confounders were used to evaluate the clinical response and overall survival, respectively. Results Overall, 109 female patients were included, 50 (45.9%) of whom received intrathecal chemotherapy with methotrexate and dexamethasone. The median treatment duration was 3 weeks (range, 1-13 weeks). Patients treated with intrathecal chemotherapy were more likely to report clinical benefit (74% versus 57.7%, adjusted odds ratio [OR] = 9.0, 95%CI=2.6-30.9, p<0.001). However, there was no difference in the time to neurologic deterioration (hazard ratio [HR] = 0.96, 95%CI= 0.57-1.59, p=0.86). Patients who received intrathecal chemotherapy did not show an increase in overall survival compared with that of patients who did not receive intrathecal chemotherapy (median overall survival = 1.8 months, 95%CI= 1.27-3.0 versus 2.5, 95%CI= 1.9-3.9, adjusted HR = 0.71, 95%CI= 0.41-1.22, p=0.21). There was a significant interaction between intrathecal chemotherapy and systemic treatment, and patients who received systemic therapy without intrathecal chemotherapy had better overall survival than that of the no-treatment group (adjusted HR = 0.38, 95%CI= 0.20-0.70, p=0.002). Conclusion Intrathecal chemotherapy did not increase overall survival or time to neurological deterioration and should not preclude or postpone systemic treatments.

Most prevalent side effects of aromatase inhibitors in the treatment of hormone-positive breast cancer: a scoping review

Hormone-positive breast cancer is the most commonly diagnosed breast neoplasm among postmenopausal women and is strongly associated with the effects of estrogens on hormone receptors of breast cells. Aromatase inhibitors are especially prescribed for treatment, and are effective to reduce mortality rates and the development of a new contralateral breast tumor. However, even with the proven efficacy and safety in use of these medications, approximately 50% of the patients abandon treatment before the prescribed period due to their side effects. The study was carried out with the objective of mapping what national and international literature declare about the most prevalent side effects caused by aromatase inhibitors in the treatment of women with hormonepositive breast cancer. We used the guidelines from the Preferred Reporting Items for Systematic Reviews and Meta-Analysis Extension for Scoping Review to elaborate this review. The methodology of choice was a scoping review aiming at synthetizing relevant information in an objective and clear manner about this drug class that is so common in breast cancer therapy, mainly benefitting women who are users of such drugs. According to the literature, reduced bone mineral density, arthralgia, hot flushes and dryness of the vaginal mucosa are the most reported symptoms, directly related with the absence of estrogen action on the body. These effects have a direct repercussion on the quality of life and on the discontinuation of treatment, leading to reduced functionality and high mortality rates. (AU)
