RESUMO

OBJECTIVE: The radical change in the treatment of breast cancer has promoted the necessity for more comprehensive training of the professionals involved, ensuring the preservation of oncological safety while also allowing for cosmetic interventions to benefit breast cancer survivors. The aim of this study was to present the methods employed in the training of breast surgeons, highlighting the importance of oncoplasty and breast reconstruction. METHODS: A literature review was conducted in two databases, identifying articles related to medical education in the context of oncoplastic surgery and breast reconstruction. We also assessed the Brazilian experience in oncoplastic centers. RESULTS: The basis for educational discussions was derived from 16 articles. We observed approaches that included hands-on courses utilizing simulator models, porcine models, cadaver labs, and fellowship programs. Positive outcomes were observed in Brazil, a fact based on seven oncoplasty training centers for senior mastologists and five training centers for junior mastologists. From 2009 to 2023, an estimated 452 seniors and 42 juniors received training, representing approximately 30% of mastologists in Brazil who have acquired training and experience in oncoplasty. CONCLUSION: Despite the limited number of publications on training methods, oncoplastic centers have made significant progress in Brazil, establishing a successful model that can be replicated in other countries.

RESUMO

INTRODUCTION: The financial impact of breast cancer has been discussed due to its high incidence and the increased costs of systemic therapy and is even more relevant in countries with low and medium socioeconomic development. OBJECTIVE: To evaluate the financial viability of using the MammaPrint™ (MP) genetic signature in a public and private system in a country with a medium socioeconomic development index. MATERIAL AND METHOD: A pharmacoeconomic trial with a cost-benefit analysis evaluating the reduction in costs of chemotherapy, support drugs, and materials used during chemotherapy infusion in high-risk hormone receptor-positive (HR+) breast cancer patients submitted to analysis using the MammaPrint™ genetic signature. RESULTS: The value of using MammaPrint™ in the Unified Health System (SUS) would bring an additional cost of US$ 1,334.56 per patient in the over-50 age group. In private medicine, the use of MammaPrint™ in the same population would result in cost savings ranging from US$ 2,422.53 to US$ 9,989.95 per patient. CONCLUSION: The use of MP in RH + breast cancer patients with high clinical risk and low genomic risk in Brazil leads to significant savings in resources when applied to supplementary healthcare. In the SUS, reducing the costs of MP for large-scale use could make its application viable. These values need to be re-evaluated in each institution, using the methodology applied in the trial, adjusting according to costs, to obtain a result that reflects its reality.

RESUMO

Evidences on the effects of chemotherapy treatment cycles on measures of muscle, mental state, social and cognitive performance are scarce. The objective of this study was to analyze the effects of chemotherapy cycles on muscle strength and activation, functional capacity, quality of life, fatigue and anxiety of women with breast cancer. Therefore, twenty-two women divided into a treatment group (n = 10; 46.6 ± 9.6 years) and control group (n = 12; 51.6 ± 7.0 years) participated in the study. Analysis of muscle performance, quality of life, fatigue and anxiety after the 2nd and 4th cycle of chemotherapy with anthracyclines were performed in women with breast cancer (TRA) and compared to healthy women (CTR). Two-way ANOVA was used to compare the variance of the means and the significance level was set as P≤0.05. The results showed Differences in the muscular activation of the vastus mediallis between the groups at post time (P = 0.038), as well as in the sit and stand test in the baseline (P<0.001) and post moment (P<0.001). Functional capacity performance was different between baseline (P<0.001) and post-time (P<0.001) groups. Additionally, the TRA group worsened the quality of life in the domains of functional capacity (P<0.001) and limitation of physical aspects (P = 0.002), besides presenting negative changes in fatigue. Thus, anthracycline chemotherapy cycles reduce muscular performance and affect biopsychosocial variables in women with breast cancer.

RESUMO

Abstract Objective: To compare the medical image interpretation's time between the conventional and automated methods of breast ultrasound in patients with breast lesions. Secondarily, to evaluate the agreement between the two methods and interobservers. Methods: This is a cross-sectional study with prospective data collection. The agreement's degrees were established in relation to the breast lesions's ultrasound descriptors. To determine the accuracy of each method, a biopsy of suspicious lesions was performed, considering the histopathological result as the diagnostic gold standard. Results: We evaluated 27 women. Conventional ultrasound used an average medical time of 10.77 minutes (± 2.55) greater than the average of 7.38 minutes (± 2.06) for automated ultrasound (p<0.001). The degrees of agreement between the methods ranged from 0.75 to 0.95 for researcher 1 and from 0.71 to 0.98 for researcher 2. Among the researchers, the degrees of agreement were between 0.63 and 1 for automated ultrasound and between 0.68 and 1 for conventional ultrasound. The area of the ROC curve for the conventional method was 0.67 (p=0.003) for researcher 1 and 0.72 (p<0.001) for researcher 2. The area of the ROC curve for the automated method was 0. 69 (p=0.001) for researcher 1 and 0.78 (p<0.001) for researcher 2. Conclusion: We observed less time devoted by the physician to automated ultrasound compared to conventional ultrasound, maintaining accuracy. There was substantial or strong to perfect interobserver agreement and substantial or strong to almost perfect agreement between the methods.

RESUMO

Introduction: Breast cancer screening in women of 70 years of age or older remains controversial due to a lack of studies that include women of this age. Methods: This ecological study evaluated data from the Brazilian National Health Service (SUS) on breast cancer screening and staging in this age group compared to 50-69-year olds, for Brazil as a whole and for its geographical regions, between 2013 and 2019. A secondary database was obtained from the outpatient data system of the SUS's Informatics Department, the Brazil Oncology Panel, the Brazilian Institute of Geography and Statistics, the Supplementary Health Agency and the Online Mortality Atlas. Results: There was a marked reduction in screening in women ≥70 years of age (annual percent change [APC] -3.5; p < 0.001) compared to those of 50-69 years of age (APC-2.2; p = 0.010). There was a trend towards an increase in clinical staging, with a greater occurrence of stages III and IV in the ≥70 group (44.3%) compared to the women of 50-69 years of age (40.8%; p < 0.001). Conclusion: Considering the increasing age of the Brazilian population and the heterogeneity among older adults women, screening for the over-70s within the SUS merits greater debate insofar as the implementation of public policies is concerned.

RESUMO

In this integrative review, we aimed to describe the records of time devoted by physicians to breast ultrasound in a review of articles in the literature, in order to observe whether the automation of the method enabled a reduction in these values. We selected articles from the Latin American and Caribbean Literature in Health Sciences (LILACS) and MEDLINE databases, through Virtual Health Library (BVS), SciELO (Scientific Electronic Library Online), PubMed, and Scopus. We obtained 561 articles, and, after excluding duplicates and screening procedures, 9 were selected, whose main information related to the guiding question of the research was synthesized and analyzed. It was concluded that the automation of breast ultrasound represents a possible strategy for optimization of the medical time dedicated to the method, but this needs to be better evaluated in comparative studies between both methods (traditional and automated), with methodology directed to the specific investigation of this potentiality.

RESUMO

This study aimed to investigate the effect of chemotherapy (CT) and its different types of regimens on the anthropometry and body composition of women with breast cancer. Three-hundred-and-four women with breast cancer were enrolled in this multicenter study. The participants were evaluated before the infusion of the first cycle of CT (pre-CT), and until two weeks after CT completion (post-CT), regarding body weight, body mass index (BMI); waist circumference (WC); waist-to-height ratio (WHtR); conicity index (C-index); fat mass index (FMI); and fat-free mass index (FFMI). CT regimens were classified as anthracycline-based (AC-doxorubicin or epirubicin); anthracyclines and taxane (ACT); cyclophosphamide, methotrexate, and 5-fluorouracil (CMF); or isolated taxanes (paclitaxel or docetaxel). Women significantly increased BMI and FMI post-CT (p < 0.001 and p = 0.007, respectively). The ACT regimen increased FMI (p < 0.001), while FFMI increased after AC (p = 0.007). It is concluded that the CT negatively impacted body composition and the type of regime had a strong influence. The ACT regimen promoted an increase in FMI compared to other regimens, and the AC increased FFMI. These findings reinforce the importance of nutritional monitoring of breast cancer patients throughout the entire CT treatment.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the impact of study methodology and evaluation type on the selection of studies during the presentation of scientific events. METHODS: A prospective, observational, transversal approach was applied to a cohort of studies that were submitted for presentation at the 2021 Brazilian Breast Cancer Symposium. Three forms of criteria (CR) were presented. CR1 was based on six criteria (method, ethics, design, originality, promotion, and social contribution); CR2 graded the studies from 0 to 10 for each study, and CR3 was based on five criteria (presentation, method, originality, scientific knowledge, and social contribution). To evaluate the item correlation, Cronbach's alpha and factorial analysis were performed. For the evaluation of differences between the tests, we used the Kruskal-Wallis and post-hoc Dunn tests. To determine the differences in the study classifications, we used the Friedman test and Namenyi's all-pairs comparisons. RESULTS: A total of 122 studies were evaluated. There was also a good correlation with the items concerning criterion 1 (α=0.730) and 3 (α=0.937). Evaluating CR1 methodology, study design and social contribution (p=0.741) represents the main factor and CR3 methodology, and the scientific contribution (p=0.994) represents the main factor. The Kruskal-Wallis test showed differences in the results (p<0.001) for all the criteria that were used [CR1-CR2 (p<0.001), CR1-CR3 (p<0.001), and CR2-CR3 (p=0.004)]. The Friedman test showed differences in the ranking of the studies (p<0.001) for all studies (p<0.01). CONCLUSION: Methodologies that use multiple criteria show good correlation and should be taken into account when ranking the best studies.

RESUMO

Objectives: This study aimed to evaluate COVID-19 effects on breast cancer screening and clinical stage at diagnosis in patients of 50-69 years of age receiving care within the public healthcare network (SUS) in 2013-2021 in Brazil and its macro-regions. Methods: This ecological study used Poisson regression to analyze trends in screening and staging. A secondary database was formed using SUS sources: outpatient data system of the SUS network and Oncology-Brazil Panel. Results: There was a reduction in screening, with an annual percent change of -5.9 (p < 0.022). The number of notified cases fell by 31.5% in 2020-2021 compared to 2018-2019. There was a 10.7% increase in the proportion of stage III/IV cases (p < 0.001) in 2020-2021 compared to 2013-2019, now surpassing the number of cases of early stage breast cancer. Conclusion: COVID-19 led to a reduction in breast cancer screening and an expressive increase in advanced tumors in users of the public healthcare network. Urgent interventions in public policies are required as the negative effects of the pandemic on the diagnosis/treatment of breast cancer are becoming apparent even earlier than expected.

RESUMO

OBJECTIVE: Previous studies have suggested the benefit of routine screening for biopsychosocial symptoms among patients with cancer. In recognition of the lack of data from low- and middle-income countries, this study sought to test and determine the effect of a mHealth program to screen biopsychological symptoms among patients with advanced breast or gynecological cancer. METHODS: This was a quasi-experimental pre-post study conducted in a public hospital located in central western Brazil. Patients diagnosed with advanced breast of gynecological cancer who were about to initiate chemotherapy treatment at this institution and had access to Internet by smartphone, computer or tablet were invited to participate. Patients received training on using the app Comfort, a program developed to rate their physical and emotional symptoms during the 6-month of the proposed study. Patients were also asked to complete the EuroQOL 5D (EQ-5D-3L) every month. Mann-Whitney U test was used to determine differences among groups of patients (engaged and non-engaged). RM-ANOVA was used to determine the effect of time on mean visual analog scale (VAS) score. RESULTS: A total of 125 patients were recruited (median age = 46.6 years old, 41.6% married). Mostly, patients possessed lower levels of education and had relatively low monthly incomes. Notably, 67.2% of patients engaged with the Comfort program, and few patients (4%) withdrew due to lack of engagement with the program or issues with internet connection. In general, patients who engaged with the program reported improvement in physical and emotional symptoms (p < 0.01), as well as in their overall quality of life (VAS; p = 0.009), compared with patients who did not engage with the program. CONCLUSIONS: This is the first mHealth program developed in Brazil for patients in a low resource setting. Our findings suggest that Comfort could be an effective resource to assist patients and health care providers track symptoms and improve patients' quality of life.

RESUMO

OBJECTIVE: Nipple-sparing mastectomy (NSM) has been traditionally used in selected cases with tumor-to-nipple distance > 2 cm and negative frozen section of the base of the nipple. Recommending NSM in unselected populations remains controversial. The present study evaluated the oncological outcomes of patients submitted to NSM in an unselected population seen at a single center. METHODS: This retrospective cohort study included unselected patients with invasive carcinoma or ductal carcinoma in situ (DCIS) who underwent NSM in 2010 to 2020. The endpoints were locoregional recurrence, disease-free survival (DFS), and overall survival (OS), irrespective of tumor size or tumor-to-nipple distance. RESULTS: Seventy-six patients (mean age 46.1 years) (58 invasive carcinomas/18 DCIS) were included. The most invasive carcinomas were hormone-positive (60%) (HER2 overexpression: 24%; triple-negative: 16%), while 39% of DCIS were high-grade. Invasive carcinomas were T2 in 66% of cases, with axillary metastases in 38%. Surgical margins were all negative. All patients with invasive carcinoma received systemic treatment and 38% underwent radiotherapy. After a mean of 34.8 months, 3 patients with invasive carcinoma (5.1%) and 1 with DCIS (5.5%) had local recurrence. Two patients had distant metastasis and died during follow-up. The 5-year OS and DFS rates for invasive carcinoma were 98% and 83%, respectively. CONCLUSION: In unselected cases, the 5-year oncological outcomes following NSM were found to be acceptable and comparable to previous reports. Further studies are required.


OBJETIVO: A mastectomia poupadora do complexo areolo-mamilar (MPM) tem sido tradicionalmente utilizada em casos selecionados com distância tumor-mamilo > 2 cm e biópsia de congelação da base do mamilo negativa. Recomendar MPM em populações não selecionadas continua controverso. Este estudo avaliou os resultados oncológicos de pacientes submetidas à MPM em uma população não selecionada atendida em um único centro. MéTODOS: Coorte retrospectivo incluindo pacientes não selecionadas com carcinoma invasivo ou carcinoma ductal in situ (CDIS) submetidas à MPM entre 2010 e 2020. Os desfechos incluíram: recorrência locorregional, sobrevida livre de doença (SLD) e sobrevida global (SG), independentemente do tamanho do tumor ou da distância tumor-mamilo. RESULTADOS: Setenta e seis pacientes (média: 46,1 anos de idade) (58 carcinomas invasivos/18 CDIS) foram incluídas. A maioria dos carcinomas invasivos era hormônio-positivo (60%) (superexpressão de HER2: 24%; triplo-negativo: 16%), enquanto 39% dos CDIS eram de alto grau histológico. Os carcinomas invasivos foram T2 em 66% dos casos, com metástases axilares em 38%. As margens cirúrgicas foram todas negativas. Todas as pacientes com carcinoma invasivo receberam tratamento sistêmico e 38% receberam radioterapia. Após um período médio de 34,8 meses, 3 pacientes com carcinoma invasivo (5,1%) e 1 com CDIS (5,5%) apresentaram recidiva local. Durante o acompanhamento, duas pacientes tiveram metástase à distância e vieram a óbito. As taxas de SG e SLD aos 5 anos para carcinoma invasivo foram de 98% e 83%, respectivamente. CONCLUSãO: Em casos não selecionados, os resultados oncológicos de 5 anos após MPM foram considerados aceitáveis e comparáveis a resultados anteriores. Estudos adicionais são necessários.

RESUMO

BACKGROUND: Triple-negative breast cancer (TNBC) is a heterogenous subtype involving different patterns of behavior and clinical course, demanding a complex, individualized sequence of treatment. The knowledge and attitudes of the affiliated members of the Brazilian Society of Mastology regarding TNBC were evaluated and a consensus regarding management and treatment was reached. METHODS: Affiliates completed a survey involving 44 objective questions. In addition, a specialist meeting was held with 27 experts and 3 ad hoc consultants. The panelists completed the survey before and after brainstorming. Answers achieving 70% of agreement were considered consensual. The chi-square test was used to compare answers between panelists and affiliates and the Kappa coefficient to calculate agreement. RESULTS: Consensus among the panelists increased from 26 (59.1%) to 32 questions (72.7%) following brainstorming (p = 0.17), including 7/10 questions on systemic treatment. Among the affiliates, consensus was achieved for 24 questions (54.5%), resulting in moderate agreement (κ = 0.445). Neoadjuvant chemotherapy should be indicated for almost all cases (except cT1a-b N0) and should include platinum agents. When indicated, immunotherapy is part of the standard of care. The panel reaffirmed the concept of no ink on tumor as indicative of adequate margins and the possibility of sentinel lymph node biopsy for cN1 patients who become cN0 following neoadjuvant therapy. Controversies remain on combining immunotherapy with capecitabine/olaparib in pertinent cases. CONCLUSION: Expert consensus was achieved for > 70% of the questions, with moderate agreement between panelists and affiliates. Educational interventions on systemic breast cancer treatment affected decision-making in 60% of the questions.

All patients with invasive carcinoma received systemic treatment and 38% underwent radiotherapy. After a mean of 34.8 months, 3 patients with invasive carcinoma (5.1%) and 1 with DCIS (5.5%) had local recurrence. Two patients had distant metastasis and died during follow-up. The 5-year OS and DFS rates for invasive carcinoma were 98% and 83%, respectively. Conclusion In unselected cases, the 5-year oncological outcomes following NSM were found to be acceptable and comparable to previous reports. Further studies are required.


Resumo Objetivo A mastectomia poupadora do complexo areolo-mamilar (MPM) tem sido tradicionalmente utilizada em casos selecionados com distância tumor-mamilo > 2 cm e biópsia de congelação da base do mamilo negativa. Recomendar MPM em populações não selecionadas continua controverso. Este estudo avaliou os resultados oncológicos de pacientes submetidas à MPM em uma população não selecionada atendida em um único centro. Métodos Coorte retrospectivo incluindo pacientes não selecionadas com carcinoma invasivo ou carcinoma ductal in situ (CDIS) submetidas à MPM entre 2010 e 2020. Os desfechos incluíram: recorrência locorregional, sobrevida livre de doença (SLD) e sobrevida global (SG), independentemente do tamanho do tumor ou da distância tumor-mamilo. Resultados Setenta e seis pacientes (média: 46,1 anos de idade) (58 carcinomas invasivos/18 CDIS) foram incluídas. A maioria dos carcinomas invasivos era hormônio-positivo (60%) (superexpressão de HER2: 24%; triplo-negativo: 16%), enquanto 39% dos CDIS eram de alto grau histológico. Os carcinomas invasivos foram T2 em 66% dos casos, com metástases axilares em 38%. As margens cirúrgicas foram todas negativas. Todas as pacientes com carcinoma invasivo receberam tratamento sistêmico e 38% receberam radioterapia. Após um período médio de 34,8 meses, 3 pacientes com carcinoma invasivo (5,1%) e 1 com CDIS (5,5%) apresentaram recidiva local. Durante o acompanhamento, duas pacientes tiveram metástase à distância e vieram a óbito. As taxas de SG e SLD aos 5 anos para carcinoma invasivo foram de 98% e 83%, respectivamente. Conclusão Em casos não selecionados, os resultados oncológicos de 5 anos após MPM foram considerados aceitáveis e comparáveis a resultados anteriores. Estudos adicionais são necessários.

RESUMO

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