RÉSUMÉ
BACKGROUND: The purpose of this study was to review and summarize the association between preoperative magnetic resonance imaging (MRI) and surgical outcomes in women with newly diagnosed invasive breast cancer from published randomized controlled trials (RCT). MATERIALS AND METHODS: Two independent researchers conducted a systematic review through a comprehensive search of electronic databases, including PubMed, Medline, Embase, Ovid, Cochrane Library, and Web of Science. If there was disagreement between the two reviewers, a third reviewer assessed the manuscript to determine whether it should be included for data extraction. The quality of the papers was assessed using the risk of bias tool, and the evidence was analyzed using GRADE. Meta-analyses using a fixed-effects model were used to estimate the pooled risk ratio (RR) and 95% confidence interval (CI). RESULTS: Initially, 21 studies were identified, 15 of which were observational comparative studies. A total of five RCTs were included, and they suggested that preoperative MRI significantly reduced the rate of immediate breast-conserving surgery and increased the risk for mastectomy. CONCLUSIONS: From the RCT perspective, preoperative MRI for newly diagnosed invasive breast cancer did not improve surgical outcomes and may increase the risk of mastectomy.

PURPOSE: Neoadjuvant chemotherapy (NAC) can be used as upfront therapy in aggressive breast cancer (BC). human epidermal growth factor receptor 2 (HER2)-low BC, defined as tumors scoring +1 or +2 on immunohistochemistry without HER2 gene amplification by in situ hybridization, lacks information on real-world data (RWD) outcomes, especially in the NAC setting. This subgroup, which does not reach the HER2 positive criteria due to its lower receptor expression, represents a distinct clinical category potentially requiring tailored therapeutic approaches. STUDY OBJECTIVE: The objective of this study is to characterize patients with BC with HER2-low status who received NAC in a Brazilian public reference center for female tumors and key outcomes such as pathological complete response (pCR), overall survival (OS), and metastasis-free survival (MFS). METHODS: A retrospective cohort study based on a large BC database from a reference cancer center in Brazil. Patients with BC that received NAC, diagnosed between 2011 and 2020, were included if they presented HER2-low status (defined as tumors scoring +1 or +2 on immunohistochemistry without HER2 gene amplification by in situ hybridization) and had complete data on outcomes. Clinical and demographic data were collected, such as age, menopausal status, Ki-67, hormone receptor expression and others. Key outcomes from the study comprised pCR (defined as ypT0/TIs/ypN0), overall survival, and metastasis-free survival (MFS). Survival analyses were conducted through the semiparametric Kaplan-Meier method to assess OS and MFS by pCR status, considering BC diagnosis as the index date. RESULTS: Overall, 297 patients were eligible and 141 were included in the study after matching the HER2-low definition. The pCR was seen in 18 out of 141 patients (12.7%). The median overall survival was 8.2 years, and the median MFS was 2.7 years. The OS of pCR was 83.4% and non-pCR was 58.1%; the DFS of pCR was 55.5% and non-pCR 40.6%. CONCLUSION: This study gives updated insights on pCR, OS, and MFS in women with HER2-low BC exposed to NAC.
RÉSUMÉ
Pathological complete response (pCR) is an important surrogate outcome to assess the effects of neoadjuvant chemotherapy (NAC). Nomograms to predict pCR have been developed with local data to better select patients who are likely to benefit from NAC; however, they were never critically reviewed regarding their internal and external validity. The purpose of this systematic review was to critically appraise nomograms published in the last 20 years (2010-2022). Articles about nomograms were searched in databases, such as PubMed/MEDLINE, Embase and Cochrane. A total of 1120 hits were found, and seven studies were included for analyses. No meta-analysis could be performed due to heterogeneous reports on outcomes, including the definition of pCR and subtypes. Most nomograms were developed in Asian centers, and nonrandomized retrospective cohorts were the most common sources of data. The most common subtype included in the studies was triple negative (50%). There were articles that included HER2+ (>80%). In one study, scholars performed additional validation of the nomogram using DFS and OS as outcomes; however, there was a lack of clarity on how such endpoints were measured. Nomograms to predict pCR cannot be extrapolated to other settings due to local preferences/availability of NAC. The main gaps identified in this review are also opportunities for future nomogram research and development.

Endometriosis is a chronic inflammatory disease that occurs in women of reproductive age. Much of the treatment involves hormone therapy that suppresses the proliferation of endometriosis lesions.Objective To compare discontinuation rates of pharmacological treatment with estrogen-progestins and progestins medications. The secondary objective is to evaluate the main side effects of these drugs in patients with endometriosis.Methods This retrospective study analyzed data from 330 patients who attended the Hospital of the State Public Servant of São Paulo from August 1999 to September 2020 and received pharmacological treatment for endometriosis. The data were obtained by review of the files of medical appointments with specialized staff.Results The median treatment time was 18 months, ranging from 1 to 168 months, and 177 patients interrupted the proposed treatment. The combined contraceptives with estrogens and progestins were significantly linked to treatment interruption, with a relative risk of 1,99 (p = 0,005). The most important side effects that resulted in treatment interruption were pain persistence (p = 0,043), weight gain (p = 0,017) and spotting (p < 0,001).

OBJECTIVES: We aimed to evaluate the pCR rate in patients receiving NAC for the treatment of breast cancer (BC) in a multicenter cohort in Brazil. Additionally, we aimed to use RWD to assess the impact of pCR on OS and DFS. METHODS: This was a retrospective, multicenter cohort study that included female patients over 18 years of age who were diagnosed with nonmetastatic breast cancer and received NAC. OS and DFS at five years were estimated by the KaplanâMeier method. Additionally, we conducted a multivariate analysis to identify factors that were significantly associated with pCR and OS. RESULTS: From 2011 to 2020, 1891 patients were included in the study, and 421 (22,3%) achieved pCR (ypT0 ypN0). Considering the presence of residual DCIS, pCR was achieved in 467 patients (23,5%). The pCR rate varied between the subtypes: HER-2+ (p = 0,016) and clinical stage IIIA and IIIB (p < 0,001). Among HER-2+ patients, those who received trastuzumab had a significantly higher pCR rate than those who did not receive trastuzumab (p < 0.0001). Similarly, patients with TNBC who received treatment with platinum-based regimens also showed higher pCR rates (p < 0.0001). OS was grouped according to pCR status, and the OS rate was 88,3% in the pCR group and 58.1% in the non-pCR group (p < 0.0001). The five-year DFS was 92.2% in the pCR group and 64.3% in the non-pCR group (p < 0.0001). CONCLUSION: The pCR rate and its prognostic value varied across BC subtypes. In our study, pCR could be used as a surrogate of favorable clinical outcome, as it was associated with higher OS and DFS rates.

During the COVID-19 pandemic, several screening exams were postponed, including mammograms. The aim of this study was to evaluate the impact of COVID-19 in mammographic screening in Brazil, considering 2015 to 2021. This was descriptive ecologic study based on the retrospective data of Brazil's mammographic screening program. A Brazilian national screening database (DATASUS - SISCAN (Cancer System Information)) was used as the data source, and the data in this database are publicly available for download and analysis. We report the number of screening rate from January 2015 to December 2021, using 2020 as reference year for COVID-19. From 2015 to 2021, 10,763,894 mammograms were performed and included in the analysis. Reductions of 39.6% and 13.3% were found in 2020 in 2021, respectively. During the pandemic's peak, the reduction was more pronounced, with maximum reductions of 82.4% in May 2020 and 34.8% in April 2021. There was an increase in the number of mammograms performed on high-risk patients from 11.2% in 2020 to 13.9% in 2021. This research demonstrated a decline in the breast cancer screening rate during the two years of the COVID-19 pandemic; this reduction will increase the burden of advanced breast cancer, potentially impacting morbidity and mortality related to this neoplasm.

Objective: This study aims to evaluate the impact of the Pink October Campaign on the increase in mammographic screening in Brazil. Study design: Ecological observational study, based on retrospective data. Methods: Brazilian national screening database (DATASUS/SISMAMA/Information System on Breast Cancer) was used as a data source and is publicly available for download and analysis. We report screening numbers and outcome rates from January 2017 to December 2021 comparing statistically (ANOVA test, post-Tukey test), age groups, regions of Brazil, and the four quarters of the year. Results: During the study period, the average number of exams performed monthly over the five years was 137,400.117. An increase in the number of mammograms performed in October was identified, as well as in the two following months, respectively 33%, 39%, and 22%, with statistical significance (p = 0.000) in relation to the three quarters of the year. In addition, in the other months, we found values below the monthly average. Statistical difference was not found in the increase in mammograms considering age groups (p = 0.5) and different regions of the country (p = 0.6). Conclusions: This study showed an increase in mammographic screening in the three months following the Pink October Campaign, so we should intensify similar actions throughout the year and not just in October.
RÉSUMÉ
Breast cancer is currently considered as a public health issue. To avoid late diagnosis, there is an attempt to use appropriate screening programs addressed to the early detection by testing the asymptomatic population in order to identify preclinical stage lesions. Methods: This is a retrospective, analytical, cross-sectional study of the notifications available in the cancer information system. The incidence of notifications from the reports of the BI-RADS™ notification system (Breast Imaging Reporting Data System) was compared between women at high and usual risk for breast cancer. Results: In the analyzed period, from 2013 to 2021, 16,065,383 screening mammographies were performed and notified in Brazil. Of these, 13,167,259 were performed in usualrisk women, whereas 2,898,124 were performed in high-risk women. To analyze the difference between reports of women at usual and high risk, the relative risk between them was calculated, as well as the necessary number to causa damage; the relative risk we found was of 0.5412 (95%CI 0.53410.5483) in B4 and relative risk of 0,433 (95%CI 0.42030.4462). As to the necessary number to cause damage, we observed 203 (95%CI 198209) for B4 and 788 (95%CI 754825) for B5. Despite the well-established need for breast cancer screening programs to reduce mortality, some aspects of screening do not have such a consensus. In this study, the incidence of reports that are suggestive of malignant breast lesions was higher among women at high risk.
RÉSUMÉ
Pregnancy-associated breast cancer is defined as a diagnosis of breast cancer during pregnancy or within 1 year of childbirth. Current evidence shows that Pregnancy-associated breast cancer is associated with poor prognosis; however, no systematic review has summarized and explored how baseline characteristics could impact survival. We aimed to explore the impact of breast cancer characteristics on death and disease relapse. A systematic review with meta-analyses was conducted by searching articles in the main databases (Medline, Embase, and Cochrane) and congress abstracts. Summarized death and disease-free survival hazard ratios were recalculated, and all meta-analyses used a random-effects model. Heterogeneity was reported using the I2 method. A total of 7143 studies were identified and only 30 studies were included. Pregnancy-associated breast cancer is associated with a 96% (HR 1.96; 95%CI 1.582.35) higher risk of death and 82% (HR 1.82; 95%CI 1.452.20) risk of death or disease relapse in comparison to a population of non-pregnancy-associated breast cancer or nulliparous breast cancer. Through sensitivity analyses, we identified that clinical outcomes were impacted, possibly due to Ki-67 levels, poorly differentiated tumors, and triple-negative breast cancer frequency in the study. As relevant sources of inconsistencies, such clinical cancer-related characteristics should be better investigated as potential confounders for upcoming Pregnancy-associated breast cancer therapeutic strategies.

INTRODUÇÃO: O câncer de mama é a neoplasia mais incidente na população feminina brasileira, sendo o linfedema uma de suas principais complicações cirúrgicas. OBJETIVO: Verificar a relação do índice de massa corpóreo e o desenvolvimento do linfedema no pós-operatório de câncer de mama, sua relação com o tipo de tratamento e ao tempo pós-cirúrgico. MATERIAIS E MÉTODOS: Foram levantados prontuários de 59 mulheres no período de maio de 2008 a fevereiro de 2009 utilizando dados da anamnese; exame físico; perimetria, volume estimado; relatos, sintomas e dados em prontuário. A análise foi feita por meio de médias e desvios padrões para as variáveis quantitativas e qualitativas (absoluta e relativa) e para verificação dos fatores de risco foi utilizado o Teste t de Student e Teste Qui-quadrado de Pearson com nível de significância de 5%. RESULTADOS: A frequência de linfedema foi de 47,5%, sendo que 40,7% eram obesas. Observou-se diferença significativa entre os grupos de linfedema e IMC (p=0,002). Nota-se ainda diferença significativa entre linfedema no grupo sem radioterapia de axila (p=0,003) e associação entre o tempo pós-cirúrgico e linfedema (p=0,006), sendo maior após 6 meses de cirurgia. CONCLUSÃO: Existe correlação entre obesidade e desenvolvimento do linfedema. Os tipos de tratamento parecem não ter influenciado o seu desenvolvimento e quanto mais tempo decorrido pós- cirurgia, maior o risco do seu aparecimento.
INTRODUCTION: Breast cancer is the most common neoplasm in the Brazilian female population, with lymphedema being one of its main surgical complications. OBJECTIVE: To verify the relationship between the body mass index and the development of lymphedema in the postoperative period of breast cancer, its relationship with the type of treatment received and the time elapsed from the surgery. MATERIALS AND METHODS: Medical records of 59 women were collected from May 2008 to February 2009 using data from anamnesis, physical exam; perimetry, estimated volume; reports, symptoms, and notes in medical records. The analysis was performed using means and standard deviations for the quantitative and qualitative variables (absolute and relative) and to verify the risk factors used, the Student's t-test and Pearson's chi-square test with a 5% significance level (0.05). RESULTS: The frequency of lymphedema was 47.5%, with 40.7% being obese. There was a significant difference between the groups of lymphedema and BMI (p=0.002). There is also a significant difference between lymphedema in the group without axillary radiotherapy (p=0.003) and an association between post-surgical time and lymphedema (p=0.006), being greater after six months of surgery. CONCLUSION: There is a correlation between obesity and the development of lymphedema. The types of treatment do not seem to have influenced their development, and the longer the surgery has elapsed, the greater the risk of their appearance.

Avaliar os resultados perinatais em gestantes com mais de 35 anos e verificar diferenças nos grupos entre 35 e 39 anos e acima de 40 anos. MÉTODOS: entre janeiro de 2000 e julho de 2003, realizou-se estudo retrospectivo por análise de fichas obstétricas de 3093 gestantes, excluindo-se 933 gestantes. As pacientes foram divididas em 3 grupos: 18 a 29 anos (grupo controle), 30 a 39 anos e mais de 40 anos. A coleta de dados foi realizada por meio de formulário padronizado e os dados foram transferidos para uma planilha eletrônica (Excel - Microsoft Office 2000). Para a análise estatística, foram utilizados o teste do chi2 e o teste de Fisher, sendo considerado risco a (alfa) menor ou igual a 5 por cento e intervalo de confiança de 95 por cento. RESULTADOS: a via de parto mais utilizada para essas pacientes foi a cesárea, tanto no grupo de 35 a 39 anos (438/792; 55,3 por cento), quanto nas gestantes com mais de 40 anos (153/236; 64,8 por cento). A taxa de prematuridade (39/236; 16,5 por cento), o baixo peso ao nascer (37/236; 15,7 por cento) e a restrição de crescimento fetal (38/236; 16,1 por cento) foram mais altas entre as gestantes tardias, com mais de 40 anos, com diferença significante em relação aos demais grupos. Quanto à ocorrência de óbito fetal, foi constatado nas gestantes de 40 anos incidência cinco vezes maior quando comparado aos outros grupos (diferença estatisticamente significante). CONCLUSAO: a comparação entre o grupo de gestantes de 35 a 39 anos com o grupo controle apenas diferiu significantemente quanto ao índice de cesáreas, o que nos permite sugerir acompanhamento pré-natal diferenciado para o grupo de gestantes acima de 40 anos
