RESUMO

PURPOSE: The study aimed to assess the frequency of Langer's arch in patients undergoing axillary dissection for breast cancer. METHODS: From January-2015 to March-2020, in a general hospital in México City, female patients undergoing axillary dissection for breast cancer were studied. The analysis involved: demographic and anthropometric data, type of surgical treatment, histopathologic diagnosis, number of lymph nodes harvested, and frequency of Langer's arch finding. RESULTS: The sample studied was 123 axillary dissections. The mean age of the patients was 59 ± 10.5-years. Modified radical mastectomy was done in 117 cases (95.1%). Ductal carcinoma occurred in 96 cases (78%). The mean number of lymph nodes harvested was 24 ± 6.5. Langer's arch finding occurred in 33 cases (26.8%). CONCLUSION: Langer's arch is frequent in our patients undergoing axillary dissection for breast cancer.

RESUMO

Obesity is a relevant risk factor in breast cancer (BC), but little is known about the effects of overweight and obesity in surgical outcomes of BC patients. The aim of this study is to analyse surgical options and associated overall survival (OS) in overweight and obese women with BC. In this study, 2143 women diagnosed between 2012 and 2016 at the Portuguese Oncology Institute of Porto (IPO-Porto) were included, and the clinicopathological information was retrieved from the institutional database. Patients were stratified by body mass index (BMI). Statistical analysis included Pearson's chi-squared test with statistical significance set at p < 0.05. Multinomial, binary logistic regression and cox proportional-hazards model were also performed to calculate odd ratios and hazard ratios with 95% confidence intervals for adjusted and non-adjusted models. The results revealed no statistical difference in histological type, topographic localization, tumour stage and receptor status and in the number of surgical interventions. Overweight women have increased probability to be subjected to sentinel node biopsy. Obese and overweight women are more likely to be submitted to conservative surgery and contrariwise, less likely to undergo total mastectomy. Patients submitted to conservative surgery and not submitted to total mastectomy had a favourable OS although without statistical significance. No significant differences were observed in OS when stratified by BMI. Our results revealed significant variations regarding the surgical options in overweight and obese patients, but these were not translated in OS difference. More research is recommended to better address treatment options in overweight and obese BC patients.

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

INTRODUCTION: Given the high rate of complete nodal response, the role of axillary lymph node dissection on staging the axilla has been questioned. This survey, addressed to breast cancer surgeons in Spain, has the objective of assessing current clinical trends on axillary staging of cN + patients treated with NAC. METHODS: An online survey was conducted among breast surgeons from the Spanish Society of Surgery (AEC), Spanish Surgical Oncology Society (SEOQ), Spanish Breast Cancer Surgeons Society (AECIMA) and Spanish Gynecology and Obstetrics Society (SEGO). It was structured in 5 sections: general information and clinical practice, knowledge of clinical trials, diagnosis work-up and nodal marking, axillary staging, and axillary treatment. RESULTS: 150 breast cancer surgeons completed the full survey (96.7%). 81.8% of respondents performed SLNB or targeted axillary dissection in cN1 patients treated with NAC. Radiological axillary response was the preferred parameter guiding the surgical strategy. The excision of the clipped node (92.0%), use of dual tracer (73.2%), and axillary US (65.9%) after treatment were the most important variables considered by respondents, to increase the accuracy of SLNB in cN + patients. CONCLUSION: This survey confirms a trend toward a less invasive approach for axillary staging in cN + patients treated with NAC among breast cancer surgeons in Spain. While there is widespread agreement in less invasive approaches to axillary staging, there is, however, a lack of consensus around treatment strategy. Further, it shows a wide heterogeneity in their clinical practice. This study highlights the need for clear evidence concerning less invasive staging procedures and their oncological safety, to ensure consistent recommendations in surgical practice.

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: Axillary surgery is still essential in the management of early breast cancer. Conservative procedures like sentinel lymph node biopsy (SLNB) are less invasive than the traditional axillary node dissection (ALND). However, some extent of ipsilateral upper limb dysfunction might still occur. This systematic review aimed to describe the incidence of lymphedema, pain, sensory, and motor disorders after SLNB in women with early breast cancer. METHODS: We conducted a systematic review of randomized controlled trials. The search was performed on Pubmed, EMBASE, CINAHAL, and Web of Science. The search was based on the following concepts: breast cancer, sentinel lymph node biopsy, axillary dissection, upper limb complications. The risk of bias was evaluated using the Cochrane Rob 2.0 toll. RESULTS: We obtained 979 unique registries from the primary search and 381 additional records from the included articles' reference lists. Fifty-one articles were assessed as full text. Nine studies were included in the review. A total of 5161 patients undergone SLNB, and 4110 patients were assessed for ipsilateral arm complications. Six months after the surgery, 0-11% of patients presented lymphedema, 11-16% pain, 2-22% sensory disorders, and 0-9% motor disorders. CONCLUSIONS: SLNB was associated with persistent postoperative complications. The burden of complications, although lower when compared to ALND, should not be ignored.

RESUMO

Describir la técnica quirúrgica de la disección axilar dirigida (DAD) usando carbón vegetal como marcador del ganglio linfático axilar metastásico al momento del diagnóstico conjuntamente con la biopsia del ganglio centinela en paciente con cáncer de mama tratada con quimioterapia neoadyuvante con respuesta completa clínica y ecográficamente, demostrando su seguridad y eficacia. Material y Métodos: Estudio retrospectivo y descriptivo. Paciente con cáncer de mama y ganglio linfático metastásico en axila ipsilateral marcado con carbón vegetal al confirmarse ese diagnóstico y tratada con quimioterapia neoadyuvante con posterior negativización tanto clínica como ecográfica del ganglio linfático metastásico. Se planificó para disección axilar dirigida (extirpación del ganglio marcado con carbón vegetal y biopsia de ganglio centinela) con el fin de demostrar la eficacia del marcador utilizado y su relación o no con el ganglio centinela. Resultados: Se comprobó la identificación certera del ganglio afectado marcado con carbón vegetal el cual no presentó migración del colorante o reacción inflamatoria local coincidiendo además con dos ganglios centinelas todos con respuesta patológica completa. El carbón permaneció 153 días desde su administración hasta la cirugía axilar. Conclusión: Esta experiencia admite el marcaje con carbón vegetal del ganglio axilar metastásico al momento de su diagnóstico como un método seguro, sencillo, económico y accesible en relación a otros métodos de marcaje, además su asociación con la biopsia del ganglio centinela nos permite prescindir de la disección axilar en caso de respuesta patológica completa, sin embargo, es importante resaltar que se necesitan evaluar más casos para obtener conclusiones determinantes(AU)

To describe the surgical technique of targeted axillary dissection using charcoal marking of the metastatic lymph node at the time of diagnosis together with sentinel node biopsy in a breast cancer patient who received neoadjuvant chemotherapy with complete clinical and sonographical response, demonstrating its safety and efficacy. Material and Methods: Retrospective and descriptive study. Patient with breast cancer and metastatic lymph node in the ipsilateral axilla which was marked with charcoal upon confirmation of this diagnosis and treated with neoadjuvant chemotherapy with subsequent clinical and sonographical negativization of the metastatic lymph node. It was planned for targeted axillary dissection (removal of charcoal-marked lymph node and sentinel node biopsy) in order to demonstrate the efficacy of the marker used and its relationship or not with the sentinel node. Results: The correct identification of the affected lymph node marked with charcoal was verified, which did not present dye migration or local inflammatory reaction, also coinciding with two sentinel nodes, all of them with a complete pathological response. The charcoal remained 153 days from its administration until the axillary surgery. Conclusion: This experience supports charcoal marking of the metastatic lymph node at the time of diagnosis as a safe, simple, inexpensive and accessible method in relation to other marking methods, in addition its association with sentinel node biopsy allows us to dispense with axillary dissection in case of complete pathological response, however it is important to highlight that more cases need to be evaluated to obtain decisive conclusions(AU)

RESUMO

Introducción El desarrollo de la técnica de la Biopsia del Ganglio Centinela (bgc) descripta por Giuliano1,2 se convirtió en el procedimiento de elección para estadificar la axila en el cáncer de mama, ya que permite seleccionar un subgrupo de pacientes en las que la linfadenectomia axilar no aporta beneficio adicional alguno. Objetivos El objetivo de este trabajo fue comunicar nuestra experiencia de 11 años en la identificación del Ganglio Centinela. Material y método Desde enero de 2004 a enero de 2015, 223 pacientes con carcinoma mamario y ganglios axilares clínicamente negativos se sometieron a bgc. Resultados En 146 pacientes el gc fue negativo, 15 fueron a vaciamiento axilar por formar parte del periodo de curva de aprendizaje y en 131 pacientes no se llevó a cabo más tratamiento axilar. En 74 casos (33,18%), se hallaron uno o más gc positivos, y se realizó disección axilar total. Conclusiones Nuestra experiencia con 223 pacientes de cáncer de mama inicial a las que se les realizó bgc indica que en tumores pequeños (hasta 4 cm), con ganglios axilares clínicamente negativos, la bgc es el procedimiento de elección para determinar estadio ganglionar.

Introduction The sentinel node biopsy technique development (snb), described by Giuliano, became the procedure of choice for staging the axilla in breast cancer. This technique allows selection of a subset of patients in which axillary lymphadenectomy does not provide any additional benefit. Objectives The aim of this study is to report our 11 years experience in sentinel node identification. Materials and method From January 2004 to January 2015, we studied 223 breast carcinoma patients with clinically negative axillary nodes who underwent snb. Results We found that the centinel node was negative in 146 patients. 15 of those patients went to an axillary lymphadenectomy as part of the learning curve period. Finally, 131 patients did not carried out further axillary treatment. We found one or more positive sentinel nodes in 74 cases (33.18%) and, as a result of this, total axillary dissection was performed. Conclusions Our experience with 223 patients who had early breast cancer, in which we conducted snb, indicates that small tumors (up to 4 cm), with clinically negative axillary nodes, the sentinel node biopsy is the procedure of choice to determine nodal stage.

RESUMO

Sentinel lymph node biopsy (SLNB) is an appropriate method for the evaluation of axillary status in cases of early breast cancer. We report our experience in treating cases evaluated using SLNB. We analyzed a total of 1192 cases assessed by means of SLNB from July 1999 to December 2007. SLNB processing was successfully completed in 1154 cases with the use of blue dye or radiolabeled 99mTc-Dextran-500, or both. Of these 1154 patients, 857 were N0(i-) (no regional lymph node metastasis, negative immunohistochemistry, IHC), 96 were N0(i+) (no regional lymph node metastasis histologically, positive IHC, no IHC cluster greater than 0.2 mm) and 201 were N1mi (greater than 0.2 mm, none greater than 2.0 mm). Most of the tumors (70 percent) were invasive ductal carcinomas and tumors were staged as T1 in 770 patients (65 percent). A total of 274 patients underwent SLNB and axillary dissections up to April 2003. The inclusion criteria were tumor size equal to or less than 3 cm in diameter, no clinically palpable axillary lymph nodes, no neoadjuvant therapy. In 19 cases, the SLN could not be identified intraoperatively. A false-negative rate of 11 percent and a negative predictive value of 88.2 percent were obtained for the 255 assessable patients. The overall concordance between SLNB and axillary lymph node status was 92 percent. SLNB sensitivity for nodes was 81 percent and specificity was 100 percent. The higher sensitivity, specificity, accuracy, and lower false-negative rates of SLNB suggest that this method may be an appropriate alternative to total axillary dissection in early breast cancer patients.

RESUMO

OBJETIVO: O objetivo deste estudo foi avaliar a morbidade cirúrgica pós-biópsia de linfonodo sentinela (BLS) ou dissecção axilar com (DA-NP) e sem preservação do nervo intercostobraquial (DA-NS). MÉTODOS: Fez-se estudo coorte prospectivo com 108 pacientes divididas em três grupos: BLS (n=35), DA-NP (n=36) e DA-NS (n=37). Foram avaliadas ocorrência de déficit sensorial, dor, linfedema, seroma e infecção no membro superior homolateral à cirurgia. Monofilamentos de Semmes-Weinstein foram usados para avaliar o déficit sensorial, perimetria braquial foi feita para avaliação da presença de linfedema e aplicado questionário de dor. Para análise estatística foram utilizados os testes ANOVA e Kruskal-Wallis. Foi feita análise bivariada e multivariada. RESULTADOS: Pelo menos uma complicação pós-cirúrgica, imediata ou tardia, ocorreu em 45/108 (41,7 por cento) pacientes avaliadas. A complicação mais comum foi dor. Houve diferença estatisticamente significante entre os três grupos somente quanto ao déficit sensorial (p=0,04). Dor, linfedema e déficit sensorial ocorreram com maior freqüência no grupo DA-NS. As pacientes dos grupos BLS e DA-NP não apresentaram diferenças estatisticamente significantes para nenhuma das variáveis analisadas. A pesquisa com os monofilamentos mostrou sensibilidade cutânea preservada em 28/35 pacientes do grupo BLS, em 25/36 pacientes do grupo DA-NP e em 10/37 pacientes do grupo DA-NS (p<0,001). CONCLUSÃO: A secção do nervo está relacionada a maior déficit sensorial havendo diferença estatisticamente significante entre os três grupos, o que não demonstrou ser significante com os demais critérios avaliados dentre os grupos analisados.

BACKGROUND: The aim of this study was to evaluate the morbidity after sentinel node biopsy (SNB) and axillary dissection with (AD-NS) or without sparing the intercostobrachial nerve (AD-NOS). Methods: A prospective cohort study was performed on 108 patients divided into three groups: SNB (n=35), AD-NS (n=36) and AD-NOS (n=37). We evaluated the incidence of sensory loss, pain, lymphedema, seroma formation and infection in the arm homolateral to the breast surgery. Semmes-Weinstein monofilaments were used to assess the sensory loss; brachial perimetry was used to evaluate presence of lymphedema and a pain questionnaire was administered. ANOVA and Kruskal-Wallis statistical tests were used. Bivariate and Multivariate analyses were performed. RESULTS: After surgery at least one complication was reported by 45/108 (41.7 percent) patients. Pain was the outcome more often reported by patients. In the three groups a significant difference was observed only regarding sensory loss (p=0.04). Pain, lymphedema, and sensory loss were more frequently found in the AD-NOS group. No significant difference was observed between SNB and AD-NS groups. Semmes-Weinstein monofilaments showed preservation of cutaneous sensitivity in 28/35 patients from the SNB group, in 25/36 patients from AD-NS group but in only 10/37 patients from AD-NOS group (p<0.001). CONCLUSION: The ICB section is associated with higher sensory loss, with statistically significant difference between the groups that were not shown to be significant with the others complications.

RESUMO

O sistema linfático é um componente do corpo humano intimamente relacionado ao sistema venoso. Entretanto, o conhecimento científico a seu respeito é limitado. A etiologia e os fatores de risco para o desenvolvimento do linfedema no pós-operatório de câncer de mama são multifatoriais e ainda não foram completamente esclarecidos. O objetivo desta revisão da literatura foi descrever o padrão linfocintilográfico e avaliar as compensações linfáticas do membro superior no pós-operatório de câncer de mama com dissecção axilar.

The lymphatic system is a component of the human body that is closely related to the venous system. However, scientific knowledge of this system is limited. The etiology and risk factors for the development of postoperative lymphedema in patients with breast cancer seem to be multifactorial and have not been fully understood yet. The objective of this review of the literature was to describe lymphoscintigraphic pattern and to evaluate upper limb lymphatic compensation following breast cancer surgery with axillary dissection.

RESUMO

O câncer de mama representa o segundo tipo mais freqüente no mundo e o que mais causa mortesentre as mulheres. O objetivo deste estudo foi analisar, por meio de prontuários fisioterapêuticos emédicos, o perfil das pacientes pós-cirurgia de câncer de mama com axillary web syndrome (AWS)do Hospital de Câncer de Pernambuco e da Faculdade Integrada do Recife (FIR). Das 112 pacientesavaliadas de abril a outubro de 2006, 7,1% apresentaram AWS. A maioria apresentou dore restrição de movimento, e 50% apresentaram linfedema. Metade realizou quadrantectomia e asdemais mastectomia, todas associadas ao esvaziamento axilar. Em 37,5%, a AWS se estendeu atéo antebraço. O tumor mais freqüente foi o carcinoma ductal invasivo e os estadiamentos I e IIapresentaram freqüência de 40%. Todas as pacientes realizaram quimioterapia e 80% realizaramradioterapia associada. Concluí-se, assim, que a AWS é significativa complicação pós-operatória eseus sintomas podem acarretar alterações na qualidade de vida.

Breast cancer represents the second most frequent type of cancer in the world and the one that most causesdeath among women. This study aimed at analyzing the profile of patients from the Cancer Hospital ofPernambuco and from FIR, after a breast cancer surgery with Axillary Web Syndrome (AWS), by meansof medical and physical therapeutic records. Within the 112 evaluated patients from April to Octoberof 2006, 7.1% presented AWS. The majority presented pain and restriction of movement, and 50%presented lymphedema. Half of the patients had a quadrantectomy done, while the remaining ones hada mastectomy, all of them associated with axillary dissection. In 37.5%, AWS reached the forearm. Themost frequent tumor was invasive ductal carcinoma and staging I and II presented frequency of 40%. Allpatients had chemotherapy done, and 80% of these had associated radiotherapy. Thus, it was concludedthat AWS is a significant post surgical complication, and its symptoms may lead to changes in the patient’slife quality.

RESUMO

Apesar do gama-probe ser a técnica que possui os melhores resultados na identificação do linfonodo sentinela (LS), a sua maior difusão nos países em desenvolvimento ainda é limitada em razão de seu custo elevado. Assim, o propósito deste estudo, realizado entre outubro de 1999 e agosto de 2004, foi determinar a eficácia da associação da linfocintigrafia pré-operatória na gama-câmara com o azul patente para biópsia do LS, sem o uso do gama-probe. Caso o linfonodo não estivesse corado com o azul patente, então era realizada amostragem do lifonodo com a projeção marcada na pele pela gama-câmara. Foram incluídas 146 pacientes com carcinomas invasivos T1-2 N0M0. As primeiras 50 pacientes foram submetidas ao esvaziamento axilar, para verificar o índice de falso-negativo da técnica, que resultou em 5,9%. A média de idade foi de 58,1 anos e a média do tamanho tumoral foi de 20,7 mm. O LS foi identificado em 98,6% das pacientes. Em 6 (4,1%), o LS foi identificado apenas pela gama-câmara e, em 2 pacientes, apenas o azul patente identificou o LS. Esses resultados demonstraram que essa técnica é uma alternativa viável para biópsia do LS no nosso meio.

Gamma-probe is the most reliable technique for sentinel node (SN) biopsy, but is remains cost-limiting for its widespread use in development countries. Then, the purpose of this study, performed from October 1999 to August 2004, was to determine the efficacy of the association of preoperative gamma camera lymphoscintigraphy and blue dye for SN biopsy, without the use of the gamma- probe. If the blue node were not find at surgery, then axillary sampling should be done in SN projection designated by gamma-camera.146 T1-2, N0, M0, invasive breast cancer patients were enrolled in this trial. The first 50 patients were submitted to axillary dissection, in order to find the false-negative rate. It was 5.9%. The mean age was 58.1 years and the mean tumor size was 20.7 mm. SN was identified in 98.6% of patients. In 6 (4.1%)patients. SN was identification was supported only by the gamma-camera, and the blue dye identified the SN IN 2 (1,4%) gamma-camera failure. These data support it as a reliable and low cost technique for SN biopsy.

RESUMO

O câncer de mama é uma das neoplasias mais estudadas em todo mundo pelo fato dessa patologia ser responsável por altas taxas de morbidade e mortalidade. O presente estudo teve como objetivo avaliar a morbidade (sensibilidade, dor, mobilidade articular e edema) relacionadas ao membro superior de pacientes com câncer de mama, após biópsia do linfonodo sentinela ou dissecção axilar. Foi realizado um estudo com 25 mulheres, desenvolvido no período de abril a novembro de 2003, junto ao Centro da Mama do Hospital São Lucas da Pontifícia Universidade Católica do Rio Grande do Sul. As características do exame físico das mulheres foram comparadas entre o pré e o pós-operatório e entre as técnicas cirúrgicas. A análise dos dados, do presente trabalho, caracteriza a biópsia do linfonodo sentinela como a técnica com menor morbidade quando comparada com a dissecção axilar.

Breast cancer is one of the most studied neoplasias in the world. It is due to the fact that this pathology is responsible for high rates of morbidity and mortality in women since the second half of the last century. The objective of the present study is to evaluate morbidity (sensibility, pain, joint mobility and edema) related to the superior limb of patients with breast cancer after biopsy of sentinel lymph node or axillary dissection. A study was performed in 25 women, from April to November of 2003 at the Breast Center of Sao Lucas Hospital at PUCRS. The characteristics of the physical exam were compared between the pre and post surgical and between the surgical techniques. Analysis of the data in the present paper characterizes the biopsy of the sentinel lymph node as a technique with less morbidity when compared to axillary dissection.
