RESUMO

INTRODUCTION: False-negative sentinel lymph node biopsy (SLNB) rates following neoadjuvant chemotherapy (NACT) in initially node-positive (cN1/2) breast cancer patients are high, but decrease when lymph nodes are clipped, ≥3 sentinel lymph nodes (SLN) are removed or dual-tracer localization (radioisotope and blue dye) is used. Radiotracer, however, is often unavailable and outcomes with blue dye alone are unknown. MATERIALS AND METHODS: Initially cT1-4, cN1/2 patients treated with NACT in 2013-2023 who underwent SLNB using blue dye alone were evaluated regarding SLN identification, axillary recurrence, disease-free and overall survival rates. RESULTS: Of 119 patients included, 19 remained cN1/2 after NACT. SLNB was performed using blue dye alone in 100 ycN0 cases (84%), with an identification rate of 96%. The SLN was negative in 70/119 cases (i.e. 59% avoided axillary dissection). The number of SLN detected was ≥3 in 55/70 cases (78%) (median 3.1; 1-6). Median age was 49 years (25-84). Most were T2 (n = 40, 57.1%), N1 (n = 64, 91.4%). Predominant subtypes were ERBB2 (52.9%) and triple-negative (20%). No axillary recurrence occurred over a median 36-month period. Five-year disease-free and overall survival were, respectively, 85.9% (95%CI: 74-99.8) and 96.3% (95%CI: 89.4-100). The ERBB2 subtype (1.99, 95%CI: 1.02-3.85, p = 0.04) and N1 lymph node status (2.58, 95%CI: 1.54-9.10, p = 0.03) were associated with a greater likelihood of undergoing SLNB alone without axillary dissection. CONCLUSIONS: SLNB with blue dye alone following NACT in initially cN1/2 patients avoided axillary dissection in almost 60% of cases, with no recurrences during the period evaluated. Longer follow-up studies are necessary.

RESUMO

Background: Nipple-sparing mastectomy (NSM), either used therapeutically or prophylactically, may yield more complications than conventional mastectomy. The incision may affect aesthetic outcome and complication rates, with periareolar incisions being associated with nipple-areolar complex (NAC) necrosis. Methods: Early complications were compared between NSM performed in 2015-2022 using inframammary fold (IMF) or periareolar incisions. Results: Overall, 180 procedures in 152 patients (bilateral NSM = 28) were included (IMF = 104; periareolar = 76). Mean age (47 versus 43.9 years; P < 0.038), mastectomy weight (312.7 versus 246.8 grams; P < 0.001), implant volume (447.5 versus 409.0 mL; P = 0.002), and use of tissue expanders (68.4% versus 50.0%; P = 0.013) were all greater with periareolar incisions. Prepectoral reconstruction was more common with IMF (18.3% versus 3.9%; P = 0.004). Forty-three complications (23.9%) were recorded (periareolar n = 27, 35%; IMF n = 16, 15.3%; P = 0.0002). NAC necrosis accounted for 17 complications (22.4%) in the periareolar group versus nine (8.5%) in the IMF group (P = 0.002). Necrosis was predominantly moderate (n = 6, 8.3% versus n = 1, 1.0%, respectively) (P = 0.014). Unadjusted odds ratios (OR) for complications [3.05; 95% confidence interval (CI): 1.27-7.26] and necrosis (3.04; 95% CI: 1.27-7.27) were higher in the periareolar group. In the multivariate analysis, necrosis was associated with periareolar incisions [adjusted odds ratio (aOR): 2.92; 95% CI: 1.14-7.44]. Prepectoral reconstruction was associated with IMF incisions (aOR: 25.51; 95% CI: 3.53-184.23; P = 0.001) and with body mass index of more than 25-30 (aOR: 37.09; 95% CI: 5.95-231.10; P < 0.001). Therapeutic mastectomies (aOR: 68.56; 95% CI: 2.50-188.36; P = 0.012) and tissue expanders (aOR: 18.36; 95% CI: 1.89-178.44; P = 0.026) were associated with seromas. Conclusions: Both incisions are viable options; however, the risk of NAC necrosis increased with the periareolar approach. Further research is required.

RESUMO

Sentinel lymph node biopsy (SLNB) at upfront surgery is the gold-standard surgical method for axillary lymph node staging in early stage breast cancer: the technique provides adequate information regarding axillary status, with similar oncological safety and lower morbidity compared to axillary dissection, despite the false negative rates. Neoadjuvant chemotherapy (NACT), traditionally used for locally advanced breast cancer, plays an important role in the treatment of early stage breast cancer, making downstaging possible in axillary lymph node and breast cancer, thus minimizing the impact of surgery and reducing morbidity, as well as enabling patients with residual disease to be selected for adjuvant treatment. In this respect, the role of SLNB has proved controversial, particularly in view of the lack of data from randomized clinical trials on this subject. Currently, the de-escalation of axillary surgery after NACT is mainly based on retrospectives studies and false negative rates. This paper reviews current evidence on the management of axillary surgery following NACT under different circumstances, with suggested recommendations in each scenario: clinically negative nodes at diagnosis and SLNB after NACT, clinically positive nodes at diagnosis and SLNB after NACT, positive SLNB following NACT and finally the possibility of omitting axillary surgery in good responders.

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.

RESUMO

PURPOSE: A nationwide lockdown was enforced in Brazil starting in March 2020 because of the COVID-19 pandemic when cancer screening activities were reduced. In this study, we evaluated the impact of the COVID-19 pandemic on breast cancer (BC) diagnosis. METHODS: We extracted data from the medical records of patients age older than 18 years who were diagnosed with BC and started treatment or follow-up in private oncology institutions in Brazil between 2018 and 2021. The primary objective was to compare the stage distribution during the COVID-19 pandemic (2020-2021) with a historical prepandemic control cohort (2018-2019). Early BC was defined as stage I-II and advanced disease as stage IV. RESULTS: We collected data for 11,753 patients with an initial diagnosis of BC, with 6,493 patients in the pandemic (2020-2021) and 5,260 patients in the prepandemic period (2018-2019). We observed a lower prevalence of early-stage BC (63.6% v 68.4%) and a higher prevalence of advanced-stage BC (16.9 v 12.7%), after the onset of the pandemic (both P < .01). This pattern was similar for both estrogen receptor-positive/human epidermal growth factor receptor 2-negative and human epidermal growth factor receptor 2-positive tumors: significantly decreased in the early stage from 69% to 67% and 68% to 58%, respectively, and a considerable increase in advanced-stage disease from 13% to 15% and 13% to 20%, respectively. For triple-negative BC, there was a significantly higher percentage of patients with advanced-stage disease during the pandemic (17% v 11%). Overall, age 50 years or older and postmenopausal status were associated with a greater risk of advanced stage at diagnosis during the pandemic period. CONCLUSION: We observed a substantial increase in the number of cases of advanced-stage BC in Brazil during the COVID-19 pandemic.

RESUMO

Introduction: Despite the lack of randomised evidence, there is a current trend towards omitting axillary surgery in cases of positive sentinel lymph node (SLN) following neoadjuvant chemotherapy (NACT). This study evaluated practice patterns of Brazilian breast surgeons when managing positive SLN following NACT. Methods: This was a nationwide electronic survey of breast surgeons affiliated with the Brazilian Society of Mastology. Management approaches for positive SLN after NACT (axillary dissection (AD), regional nodal irradiation (RNI) or no additional treatment) were evaluated as a function of residual disease volume in the SLN (macro-metastasis, micro-metastasis or isolated tumour cells (ITC)). Results: Survey response rate was 49%, with 799/1,627 questionnaires returned. Most respondents were <50 years old (61%), lived in south-eastern Brazil (50%), in a major city (67%), worked in an academic institute (80%) and were board-certified (80%). AD recommendation rate decreased according to residual nodal disease volume: 91% of respondents recommended AD for cases of macro-metastasis, 64% for micro-metastasis and 38% for ITC (p < 0.00001). Furthermore, 35% would recommend no additional surgery for micro-metastasis, while 27% would recommend no treatment at all for ITC (p < 0.00001). Not working in an academic institute was associated with RNI for micro-metastasis (p = 0.02), but not for macro-metastasis or ITC. Being board-certified did not affect axillary management. Conclusion: Most respondents would recommend AD and/or RNI in residual nodal disease following NACT irrespective of disease volume. Nevertheless, a trend towards surgical de-escalation was found with low-volume disease (micro-metastasis and ITC). Ongoing randomised trials will clarify the impact of this trend.

RESUMO

PURPOSE: To evaluate the impact of the ACOSOG Z0011 trial on axillary breast cancer surgery management in Brazil following publication of that study (2010) and again in 2020. PATIENTS AND METHODS: A survey of members of the Brazilian Society of Mastology. RESULTS: Of 1627 breast surgeons, 799 (49.1%) completed and returned the questionnaire. For patients with the Z11 inclusion criteria, following detection of a positive sentinel lymph node (SLN), axillary dissection (AD) was recommended by 99.2% of respondents before publication of the study, 47.5% in 2010 and 18.5% in 2020 (p < 0.001). In breast-conserving surgery, if there were micro-metastases, 2.6% would perform AD, 30.3% axillary radiotherapy, and 67.1% no additional axillary treatment, while with macro-metastases, these proportions were 21.3%, 52.2%, and 26.5%, respectively. In cases of mastectomy and of nodal extracapsular extension, 43.4% and 36% of surgeons, respectively, recommended AD. For clinically negative axilla and suspicious findings at ultrasonography, 69% of the surgeons would apply the Z11 approach. Most applied the Z11 criteria in cases of younger patients (83.6%) and triple-negative and/or HER2 positive tumors (74%). AD was significantly more likely to be recommended by surgeons who did not work in academic institutes, who worked in locations other than capital cities, who were not board-certified, and who were ≥ 50 years old. CONCLUSIONS: This survey revealed substantial changes in axillary surgery management in cN0/pathologically positive SLN, particularly following publication of the updated Z11 results and other similar studies. A better education environment and long-term follow-up were factors associated with the incorporation of Z11-related changes in practice.

RESUMO

PURPOSE: The COVID-19 pandemic has impacted early breast cancer (EBC) treatment worldwide. This study analyzed how Brazilian breast specialists are managing EBC. METHODS: An electronic survey was conducted with members of the Brazilian Society of Breast Cancer Specialists (SBM) between April 30 and May 11, 2020. Bivariate analysis was used to describe changes in how specialists managed EBC at the beginning and during the pandemic, according to breast cancer subtype and oncoplastic surgery. RESULTS: The response rate was 34.4% (503/1462 specialists). Most of the respondents (324; 64.4%) lived in a state capital city, were board-certified as breast specialists (395; 78.5%) and either worked in an academic institute or one associated with breast cancer treatment (390; 77.5%). The best response rate was from the southeast of the country (240; 47.7%) followed by the northeast (128; 25.4%). At the beginning of the pandemic, 43% changed their management approach. As the outbreak progressed, this proportion increased to 69.8% (p < 0.001). The southeast of the country (p = 0.005) and the state capital cities (p < 0.001) were associated with changes at the beginning of the pandemic, while being female (p = 0.001) was associated with changes during the pandemic. For hormone receptor-positive tumors with the best prognosis (Ki-67 < 20%), 47.9% and 17.7% of specialists would recommend neoadjuvant endocrine therapy for postmenopausal and premenopausal women, respectively. For tumors with poorer prognosis (Ki-67 > 30%), 34% and 10.9% would recommend it for postmenopausal and premenopausal women, respectively. Menopausal status significantly affected whether the specialists changed their approach (p < 0.00001). For tumors ≥ 1.0 cm, 42.9% of respondents would recommend neoadjuvant systemic therapy for triple-negative tumors and 39.6% for HER2 + tumors. Overall, 63.4% would recommend immediate total breast reconstruction, while only 3.4% would recommend autologous reconstruction. In breast-conserving surgery, 75% would recommend partial breast reconstruction; however, 54.1% would contraindicate mammoplasty. Furthermore, 84.9% of respondents would not recommend prophylactic mastectomy in cases of BRCA mutation. CONCLUSIONS: Important changes occurred in EBC treatment, particularly for hormone receptor-positive tumors, as the outbreak progressed in each region. Systematic monitoring could assure appropriate breast cancer treatment, mitigating the impact of the pandemic.

RESUMO

The present paper reports on the local treatment of breast cancer from a historical perspective. A search for articles written in English was made in the Medline and EMBASE databases, and 40 papers were selected. Over the past 10 years, various randomized, controlled clinical trials on the local treatment of breast cancer indicated that patients with the same molecular subtype may receive different individualized surgical treatments aimed at optimizing systemic adjuvant therapy. With a view to retaining the gains made in disease-free and overall survival, surgical techniques have advanced from radical surgery to conservative mastectomies, thus reducing sequelae, while adjuvant and neoadjuvant therapies have contributed toward controlling the disease, both distant metastases and local recurrence. Current studies evaluate whether future breast cancer therapy may even succeed in eliminating surgery to the breast and axilla altogether.

RESUMO

BACKGROUND: Taxanes usually follow anthracyclines in breast cancer neo/adjuvant treatment, likely because of their later introduction into clinical practice. However, there is no biological rationale that justifies this current standard of care. We compared a taxane followed by an anthracycline-based regimen with the reverse sequence in the neoadjuvant setting. PATIENTS AND METHODS: In a randomized, open-label, single-center phase II trial, women with inoperable, locally advanced, HER2-negative breast cancer were stratified by hormone receptor status and randomized to three cycles of docetaxel (T) followed by three cycles of fluorouracil, doxorubicin, and cyclophosphamide (FAC) versus three cycles of FAC followed by three cycles of docetaxel. Surgery, radiotherapy, and adjuvant hormonal therapy were administered as per local guidelines. The primary endpoint was pathological complete response (pCR), and secondary endpoints included toxicity, event-free survival (EFS), and overall survival (OS). RESULTS: Treatment sequence did not improve pCR, which was 7% with T-FAC and 3% with FAC-T. However, after a median follow-up of 79 months, the 5-year EFS rate was 75.7% (95% confidence interval [CI], 65.4%-87.7%) with T-FAC and 48.2% (95% CI, 37.0%-62.7%) with FAC-T (hazard ratio [HR], 0.46; 95% CI, 0.26-0.81; log-rank p = .0054), and the 5-year OS rate was 89.7% (95% CI, 82.2%-97.8%) with T-FAC and 64.7% (95% CI, 53.6%-78.1%) with FAC-T (HR, 0.41; 95% CI, 0.22-0.78; p = .0052). There were no unexpected toxicities. CONCLUSION: We showed for the first time an improvement in EFS and OS with taxane-first compared with anthracycline-first sequencing chemotherapy in HER2-negative, locally advanced breast cancer. Confirmation of these results may have implications for clinical practice. This trial was registered with Clinicatrials.gov identifier NCT01270373. IMPLICATIONS FOR PRACTICE: The NeoSAMBA trial showed a benefit for taxane-first sequencing chemotherapy consistent with the systematic review of the literature as well as the larger Neo-tAnGo study. Many recent and current ongoing clinical trials have already followed this treatment strategy. As a taxane-before-anthracycline sequence carries neither an incremental cost nor an increased toxicity, and given the available literature on this issue, reinforced that taxane-first regimen can be easily incorporated into daily clinical practice while awaiting confirmation of these findings from larger trials.

RESUMO

OBJECTIVES: To compare imprint cytology and paraffin section histology for sentinel lymph node detection in women with breast cancer treated with neoadjuvant chemotherapy. METHOD: A cross-sectional study and report of the sentinel lymph node statuses of 64 patients with breast cancer who underwent intraoperative imprint cytology and neoadjuvant chemotherapy in a referral cancer institute in Rio de Janeiro, Brazil, between 2014 and 2016. RESULTS: The mean age was 51 years. The most common histological type was invasive ductal carcinoma (93.75%), and the most common differentiation grade was 2 (62.5%). Overall, 153 lymph nodes were identified, with a mean of 2.39/case. Thirty-four lymph nodes tested positive for malignancy by imprint cytology, and 55 tested positive by histology. Of the 55 positive lymph nodes, 41 (74.5%) involved macrometastases, and 14 (25.5%) involved micrometastases. There were 21 false negatives with imprint cytology, namely, 7 for macrometastases and 14 for micrometastases, resulting in a rate of 17.6%. The sensitivity of imprint cytology was 61.8%, with a specificity and positive predictive value of 100%, a negative predictive value of 82.4% and an accuracy of 86.3%. The method presented null sensitivity for the identification of micrometastases. CONCLUSIONS: The false-negative rate with imprint cytology was associated with the number of sentinel lymph nodes obtained. The rate found for complete response to neoadjuvant chemotherapy was comparable to the rates reported in the literature. The accuracy of imprint cytology was good, and its specificity was excellent for sentinel lymph node detection; however, the method was unable to detect lymph node micrometastases.

The sensitivity of imprint cytology was 61.8%, with a specificity and positive predictive value of 100%, a negative predictive value of 82.4% and an accuracy of 86.3%. The method presented null sensitivity for the identification of micrometastases. CONCLUSIONS: The false-negative rate with imprint cytology was associated with the number of sentinel lymph nodes obtained. The rate found for complete response to neoadjuvant chemotherapy was comparable to the rates reported in the literature. The accuracy of imprint cytology was good, and its specificity was excellent for sentinel lymph node detection; however, the method was unable to detect lymph node micrometastases.

RESUMO

Introdução: O linfedema é a complicação mais comum após o tratamento do câncer de mama. Quando se manifesta antes do tratamento cirúrgico, como condição clínica por si só, é visto como um critério de inoperabilidade, representando um fator de mau prognóstico. Relato do caso: Este artigo visa a descrever a evolução clínica de uma paciente com linfedema de membro superior prévio à cirurgia para o câncer de mama, à condução do tratamento fisioterapêutico e à viabilidade do procedimento cirúrgico. Conclusão: Por meio deste relato de caso, foi possível descrever o tratamento fisioterapêutico de uma paciente com linfedema prévio à cirurgia para o câncer de mama. A equipe de fisioterapia pôde atuar em parceria com a equipe médica, controlando a descompensação linfática e auxiliando no caminho até a realização do procedimento cirúrgico. O cuidado fisioterapêutico se mostra fundamental desde o início do tratamento oncológico, de forma a detectar precocemente sintomas e distúrbios, intervindo de maneira eficaz e resolutiva e buscando proporcionar qualidade de vida e os melhores resultados possíveis para as pacientes.


Introduction: Lymphedema is the most common complication after breast cancer treatment. When it manifests itself before surgical treatment, as a clinical condition alone, it is seen as a criterion of inoperability, representing a factor of poor prognosis. Case report: This article aims to describe the clinical evolution of a patient with upper limb lymphedema prior to surgery for breast cancer, the conduct of the physiotherapeutic treatment and the feasibility of the surgical procedure. Conclusion: Through this case report it was possible to describe the physiotherapeutic treatment of a patient with lymphedema prior to surgery for breast cancer. The physiotherapy team can work in partnership with the medical team, controlling the lymphatic decompensation and assisting in the way until the surgical procedure is performed. Physiotherapeutic care has been fundamental since the beginning of cancer treatment, in order to detect early symptoms and disorders, intervening effectively and resolutely and seeking to provide quality of life and the best possible outcomes for patients.
