Breast cancer after thoracic radiotherapy in young patients: what does the radiologist need to know? / Câncer de mama após radioterapia torácica em pacientes jovens: o que o radiologista precisa saber?

Abstract Radiation-induced secondary tumors constitute a rare complication of radiation therapy and typically occur in or near the irradiated area. Women who undergo thoracic radiotherapy before 30 years of age have a significantly greater lifetime risk of developing breast cancer than do those in the general population. It is recommended that a patient who has previously received thoracic radiotherapy with a radiation dose ≥ 10 Gy subsequently undergo annual screening with mammography and magnetic resonance imaging, beginning eight years after the initial treatment or when the patient has reached 25 years of age (whichever comes later). The treatment of secondary breast cancer in this population should be individualized and should be discussed with a multidisciplinary team to avoid toxicity related to the treatment of the primary cancer.

Resumo Os cânceres secundários induzidos por radiação são complicações raras da radioterapia e geralmente ocorrem na área tratada ou próximo a ela. Mulheres com menos de 30 anos de idade tratadas com radioterapia torácica têm risco significativamente aumentado de desenvolver câncer de mama ao longo da vida, em comparação com a população em geral. Para as pacientes tratadas com irradiação torácica com dose igual ou superior a 10 Gy é recomendado rastreamento anual com mamografia e ressonância magnética iniciando oito anos após o tratamento, desde que este início seja após 25 anos de idade. O tratamento do câncer de mama secundário nessa população deve ser individualizado e discutido com equipe multidisciplinar, para evitar toxicidade relacionada ao tratamento do câncer primário.

Computed tomography assessment of body composition in patients with nonmetastatic breast cancer: what are the best prognostic markers? / Avaliação da composição corporal por tomografia computadorizada em pacientes com câncer de mama não metastático: quais os melhores marcadores de prognóstico?

Abstract Objective: To correlate body composition measures, based on computed tomography (CT) analysis of muscle mass and adipose tissue, with disease-free survival in breast cancer patients. Materials and Methods: This single-center retrospective study included 262 female patients with nonmetastatic breast cancer. Body composition was assessed on a pretreatment CT scan (at the L3 level). The analysis included quantification of the areas of subcutaneous adipose tissue (SAT), visceral adipose tissue (VAT), and skeletal muscle mass, as well as of the mean skeletal muscle density. The VAT/SAT ratio, skeletal mass index (SMI), and skeletal muscle gauge (SMG) were calculated. Results: Of the 262 patients evaluated, 175 (66.8%) were classified as overweight or obese on the basis of their body mass index. We observed low SMI in 35 patients (13.4%) and elevated VAT in 123 (46.9%). Disease-free survival was significantly shorter in the patients who underwent neoadjuvant chemotherapy (p = 0.044), in those with a low SMI (p = 0.006), in those with low SMG (p = 0.013), and in those with a low VAT/SAT ratio (p = 0.050). In a multivariate analysis, only SMG, the VAT/SAT ratio, and having undergone neoadjuvant chemotherapy retained their statistical significance. Conclusion: Our results confirm that low SMG and the VAT/SAT ratio can be used as imaging biomarkers to assess prognosis in patients with nonmetastatic breast cancer.

Resumo Objetivo: Correlacionar medidas de composição corporal baseadas na análise por tomografia computadorizada (TC) da massa muscular e tecido adiposo com a sobrevida livre de doença em pacientes com câncer de mama. Materiais e Métodos: Estudo retrospectivo unicêntrico que incluiu 262 mulheres com câncer de mama não metastático. Avaliação da composição corporal foi realizada na TC pré-tratamento (nível de L3), incluindo tecido adiposo subcutâneo (SAT) e tecido adiposo visceral (VAT), massa muscular esquelética e densidade do músculo esquelético. A relação VAT/SAT, o índice de massa esquelética (SMI) e o produto do músculo esquelético (SMG) foram calculados. Resultados: De acordo com o índice de massa corporal, 175 (66,8%) pacientes foram classificadas com sobrepeso ou obesidade. Baixo SMI foi observado em 35 (13,4%) pacientes e VAT elevado, em 123 (46,9%). Houve uma redução significativa na sobrevida livre de doença nas pacientes que realizaram quimioterapia neoadjuvante (p = 0,044), nas com baixo SMI (p = 0,006), baixo SMG (p = 0,013) e baixa relação VAT/SAT (p = 0,050). Na análise multivariada, apenas SMG, relação VAT/SAT e quimioterapia neoadjuvante confirmaram significância estatística. Conclusão: Nossos resultados confirmaram que SMG e relação VAT/SAT baixos podem ser usados como importantes biomarcadores de imagem para avaliar o prognóstico em pacientes com câncer de mama não metastático.

An introduction to male breast cancer for urologists: epidemiology, diagnosis, principles of treatment, and special situations

ABSTRACT Breast cancer (BC) is mainly considered a disease in women, but male BC (MaBC) accounts for approximately 1.0% of BC diagnoses and 0.5% of malignant neoplasms in the western population. The stigmatization of MaBC, the fact that men are less likely to undergo regular health screenings, and the limited knowledge of health professionals about MaBC contribute to men being diagnosed at more advanced stages. The aim of this article is to increase the visibility of MaBC among urologists, who have more contact with male patients. This review highlights key points about the disease, the risk factors associated with MaBC, and the options for treatment. Obesity and increased population longevity are among the important risk factors for MaBC, but published studies have identified family history as extremely relevant in these patients and associated with a high penetrance at any age. There is currently no screening for MaBC in the general population, but the possibility of screening in men at high risk for developing BC can be considered. The treatment of MaBC is multidisciplinary, and, because of its rarity, there are no robust clinical studies evaluating the role of systemic therapies in the management of both localized and metastatic disease. Therefore, in current clinical practice, treatment strategies for men with breast cancer are extrapolated from information arising from studies in female patients.

Benefits of a standardized protocol for axillary management after neoadjuvant chemotherapy in a single center

Introduction: The axillary lymph node status is one of the most important prognostic factors in breast cancer. For locally advanced tumors, neoadjuvant chemotherapy favors higher rates of breast lumpectomy and downstaging tumor burden of axilla. The aim of this study was to evaluate the use of a standardized image-guided protocol after neoadjuvant chemotherapy to enable sentinel node dissection in patients with axillary downstaging, avoiding axillary dissection. Methods: Retrospective cohort study of data collected from medical records of patients who underwent neoadjuvant chemotherapy in a single center, from January 2014 to December 2018. The protocol comprises the placement of a metal clip in positive axillary lymph node, in patients with up to two clinically abnormal lymph nodes presented on imaging. After neoadjuvant chemotherapy, and once a radiologic complete response was achieved, sentinel node dissection was performed using blue dye and radiotracer. Axillary dissection were avoided in patients whose clipped sentinel node were negative for metastasis and in patients with three identified and negative sentinel node dissection. Results: A total of 471 patients were analyzed for this study: 303 before and 165 after the implementation of the protocol; 3 cases were excluded. The rate of sentinel node dissection in clinical nodes positive patients was statistically higher in this group when compared to patients treated before the protocol implementation (22.8% vs. 40.8%; p=0.001). Patients with triple negative and HER2-positive tumors underwent sentinel node dissection more frequently when compared to luminal tumors (p=0.03). After multivariate analysis, the variables that were associated with a greater chance of performing sentinel node dissection were clinical staging, type of surgery performed and implementation of the axillary assessment protocol. Conclusions: The results showed that the use of an easily and accessible image-guided protocol can improve sentinel node dissection in selected patients, even if the lymph node was positive previously to neoadjuvant treatment.

Radiation therapy with elective lymph node irradiation for breast cancer: dosimetric study and impact on cardiovascular risk and second neoplasms

SUMMARY OBJECTIVE: The aim of this study was to perform dosimetric analysis of radiotherapy (RT) plans with or without elective nodal irradiation (ENI) and estimate whether the increase in mean doses (MDs) in the heart and lungs with ENI may lead to late side effects that may surpass the benefits of treatment. METHODS: The dosimetric analysis of 30 treatment plans was done with or without ENI. The planning and dose-volume histograms were analyzed, and the impact on the mortality of cardiovascular and lung cancer was estimated based on the correlation of the dosimetric data with data from population studies. RESULTS: RT with ENI increased the doses in the lungs and heterogeneity in the plans compared to breast-exclusive RT. When the increase in MDs is correlated with the increase of late side-effect risks, the most important effect of ENI is the increased risk of lung cancer, especially in patients who smoke (average increase in absolute risk=1.38%). The increase in the absolute risk of cardiovascular diseases was below 0.1% in the all the situations analyzed. CONCLUSIONS: ENI increases the heterogeneity and the doses at the lungs. When recommending ENI, the risks and benefits must be taken into account, considering the oncology factors and the plan of each patient. Special attention must be given to patients who smoke as ENI may lead to a significant increase in MD in the lung and the increased risk of radiation-induced lung cancer may surpass the benefits from this treatment.

Pleomorphic adenoma of the breast

Pleomorphic adenoma (PA) is a common tumor of the salivary gland, but rarely occurs in the breast. PA of the breast is a benign tumor that usually presents as a periareolar nodule. Core-needle biopsies may yield misdiagnosis with complex fibroadenoma, phyllodes tumor and metaplastic breast cancer due to the mixture of stromal and epithelial elements. We present a case of PA of the breast suspected after core-needle biopsy, but confirmed after surgical excision. The importance to make a correct diagnosis consists in avoid extensive unnecessary surgery, such as mastectomy, since PA can be treated with local surgical resection.

Postoperative complications following simultaneous therapeutic and contralateral prophylactic nipple-sparing mastectomy: a retrospective study

Introduction: Nipple-Sparing Mastectomy (NSM) is increasingly indicated for therapeutic and prophylactic purposes due to better cosmetic results with nipple maintenance. Postoperative complications have not been compared among patients who have undergone simultaneous therapeutic and contralateral prophylactic NSM. The aim of the present study was to evaluate the incidence and risk factors for postoperative complications in bilateral/unilateral NSMs, and therapeutic and/or prophylactic NSMs. Methods: Retrospective study of patients who underwent NSM between 2007 and 2017 at A.C. Camargo Cancer Center. Results: Among 290 patients, 367 NSMs were performed, 64 simultaneous therapeutic and contralateral prophylactic NSM. The latter were associated with more postoperative complications (OR=3.42; p=0.002), mainly skin flap necrosis (OR=3.79; p=0.004), hematoma (OR=7.1; p=0.002), wound infection (OR=3.45; p=0.012), and nipple-areola complex (NAC) loss (OR=9.63; p=0.003). Of the 367 NSMs, 213 were unilateral NSMs, which were associated with lower rates of postoperative complications (OR=0.44; p=0.003), especially skin flap necrosis (OR=0.32; p=0.001), hematoma (OR=0.29; p=0.008), wound infection (OR=0.22; p=0.0001), and reoperation (OR=0.38; p=0.008). Obesity was related to more postoperative complications (OR=2.55; p=0.01), mainly hematoma (OR=3.54; p=0.016), reoperation (OR=2.68; p=0.023), and NAC loss (OR=3.54; p=0.016). Patients' age (p=0.169), their smoking status (p=0.138), breast ptosis (0.189), previous chest radiotherapy (p 1), or previous breast surgery (p=0.338) were not related to higher chances of postoperative complications. Conclusions: Results suggest that performing therapeutic and contralateral prophylactic NSM as separated procedures may represent a good strategy for minimizing postoperative complications.

Accuracy of ultrasound-guided core-needle biopsy confronted with pathological findings and comparison of its costs with vacuum-assisted biopsy's costs

Introduction: Breast cancer screening has enhanced early­stage diagnosis by detection of impalpable tumors which require histopathological evaluation. Main percutaneous biopsy types are core-needle biopsy (CNB) and vacuum-assisted biopsy (VAB). CNB is less invasive and related to less bleeding and pain. VAB allows larger tissue samples and permits metal clip placement in biopsy bed for posterior localization in case of surgery. Access to VAB is restricted in Brazil due to its high costs. Objectives: To evaluate the agreement between pathological results of ultrasound (US) guided CNB with metal clip placement and surgery and settle false negative rates (FNR), sensibility, specificity, and accuracy of this method, for breast lesions < 20 mm. Methods: 388 US-guided CNB were retrospectively reviewed. Results: Surgical excision was performed in 317 patients. Overall FNR was 9.8%, (5.2% for lesions 10­20 mm), sensibility 90.2% (94.8% for lesions 10­20 mm), specificity 94.9% (94.1% for lesions 10­20 mm), and accuracy 91.1% (94.7% for lesions 10­20 mm). Cost of VAB varies from 2.2 to 12.5 times US-guided CNB. With metal clip placement, VAB costs 1.95 to 5.2 times US-guided CNB. Conclusions: For lesions that can be identified in US, CNB with metal clip placement has high sensitivity, specificity, and accuracy, as well as low FNR.

Breast implant-associated anaplastic large cell lymphoma in li-fraumeni syndrome: case-based literature review / Linfoma anaplásico de grandes células associado a implante na síndrome de Li-Fraumeni: relato de caso baseado em revisão de literatura

Breast implant-associated anaplastic large cell lymphoma is a rare disease related to chronic seroma around breast implants. Breast implant-associated anaplastic large cell lymphoma has been recently recognized by the World Health Organization as a type of T-cell non-Hodgkin lymphoma of the breast. The main features comprise chronic seroma which develops a year posterior to breast surgery, with symptoms such as breast pain, swelling, skin hyperemia and a nodule or mass of the breast. Li-Fraumeni Syndrome is associated with germline TP53 mutation and enhances the risks of developing many types of cancers, including breast and hematologic malignancies. We report a case of a 56-year-old female with Li-Fraumeni Syndrome and a history of breast cancer who underwent a mastectomy to treat breast cancer and prophylactic contralateral nipple-sparing mastectomy followed by bilateral breast implant reconstruction with textured silicone implants. This patient developed Breast implant-associated anaplastic large cell lymphoma seven years later. A literature review on multidisciplinary approach to this condition was performed.

O linfoma anaplásico de células grandes associado ao implante mamário é uma doença rara relacionada ao seroma crônico em torno dos implantes mamários. O linfoma anaplásico de células grandes associado ao implante foi recentemente reconhecido pela Organização Mundial de Saúde como um tipo de linfoma não-Hodgkin de células T da mama. As principais características incluem o seroma crônico que se desenvolve um ano depois da cirurgia da mama, com sintomas como dor na mama, inchaço, hiperemia da pele e um nódulo ou massa da mama. A síndrome de Li-Fraumeni está associada à mutação da linha germinativa no TP53 e aumenta o risco de desenvolvimento de muitos tipos de câncer, incluindo neoplasias mamárias e hematológicas. Relatamos um caso de uma mulher de 56 anos de idade com Síndrome de Li-Fraumeni e um histórico de câncer de mama submetido a uma mastectomia para tratar câncer de mama e mastectomia profilática contralateral poupadora de mamilo seguida de reconstrução bilateral de implantes mamários com implantes de silicone texturizados. Esta paciente desenvolveu linfoma anaplásico de células grandes associado ao implante mamário sete anos depois. Foi realizada uma revisão da literatura sobre uma abordagem multidisciplinar para essa condição.

18F-FDG PET/CT helps to find occult carcinoma in a patient with multiple breast masses at magnetic resonance imaging / PET/CT com 18F-FDG ajuda a identificar carcinoma oculto em paciente com múltiplos nódulos mamários na ressonância magnética

52-year-old female patient with diagnosis of invasive carcinoma in the left breast and metastatic lymph node in the right axilla. Magnetic resonance imaging showed multiple breast masses, with four previous negative biopsies in the right breast. 18F-FDG positron emission tomography (PET)/computed tomography (CT) was performed in prone position, dedicated to breast evaluation. It showed increased uptake in a mass in the right breast. After PET/magnetic resonance imaging (MRI) fusion and second-look breast ultrasound, this mass was submitted to percutaneous biopsy, which confirmed a second invasive breast carcinoma and changed patients' treatment. This is an example of how PET/MRI dedicated devices can improve the evaluation of selected breast lesions.

Paciente do sexo feminino, de 52 anos, com diagnóstico de carcinoma invasivo na mama esquerda e linfonodo metastático na axila direita. A ressonância magnética mostrou múltiplos nódulos mamários bilaterais, com quatro biópsias anteriores negativas na mama direita. 18F-FDG PET/tomografia computadorizada (CT) foi realizado em decúbito ventral, dedicada à avaliação das mamas, demonstrou aumento da captação em um nódulo na mama direita. Depois de fusão das imagens do PET/CT com a ressonância magnética (RM) e ultrassonografia direcionada, esta lesão foi submetida à biópsia percutânea, que confirmou um segundo carcinoma invasivo na mama direita, alterando o tratamento. Este é um exemplo de como os dispositivos dedicados de PET/RM podem melhorar a avaliação das lesões mamárias selecionadas.

Impact of breast magnetic resonance imaging on the locoregional staging and management of breast cancer / Impacto da ressonância magnética das mamas no estadiamento locorregional e manejo do câncer de mama

Abstract Objective: To assess the impact of magnetic resonance imaging (MRI) on the locoregional staging of breast cancer. Materials and Methods: We evaluated 61 patients with breast cancer who underwent pre-treatment breast MRI, between August 2015 and April 2016. An experienced breast surgeon determined the surgical treatment, on the basis of the findings of conventional imaging examinations, and made a subsequent treatment recommendation based on the MRI findings, then determining whether the MRI changed the approach, as well as whether it had a positive or negative impact on the treatment. Results: The mean age was 50.8 years (standard deviation, 12.0 years). The most common histological type was invasive breast carcinoma of no special type (in 68.9%), and the most common molecular subtype was luminal B (in 45.9%). Breast MRI modified the therapeutic management in 23.0% of the cases evaluated, having a positive impact in 82.7%. Conclusion: Breast MRI is an useful tool for the locoregional staging of breast cancer, because it provides useful information that can have a positive impact on patient treatment.

Resumo Objetivo: Avaliar o impacto do uso da ressonância magnética (RM) no estadiamento pré-operatório do câncer de mama. Materiais e Métodos: Foram avaliadas 61 pacientes com carcinoma mamário submetidas a RM das mamas, no período de agosto de 2015 a abril de 2016. Um mastologista foi questionado sobre a conduta terapêutica indicada diante dos dados da paciente e dos exames convencionais e, após realização da RM, foi novamente questionado sobre a conduta para determinar se houve mudança e impacto no tratamento. Resultados: A média de idade das pacientes foi 50,8 anos (desvio-padrão: 12,0), o tipo histológico mais frequente foi carcinoma mamário invasivo tipo não especial (68,9%) e o imunofenótipo mais prevalente foi luminal B (45,9%). A RM das mamas mudou a conduta terapêutica em 23% dos casos, com impacto positivo em 82,7%. Conclusão: A RM das mamas é instrumento útil no estadiamento locorregional do câncer de mama, sendo capaz de adicionar informações que tenham impacto positivo no tratamento.

Mammary adenectomy followed by immediate reconstruction for treatment of patients with early-infiltrating breast carcinoma: a cohort study

ABSTRACT BACKGROUND: Use of mammary adenectomy for breast carcinoma treatment remains controversial. OBJECTIVE: This study aimed to verify the oncological safety of mammary adenectomy and immediate breast reconstruction for treating selected patients with infiltrating breast carcinoma and to evaluate patients' satisfaction with the reconstructed breasts. DESIGN AND SETTING: Cohort study conducted among patients treated at Hospital Sírio-Libanês, São Paulo, Brazil. METHODS: This study was based on 152 selected patients (161 operated breasts) with infiltrating breast carcinoma who underwent mammary adenectomy and immediate breast reconstruction. In all patients, the diameter of the largest focus of the tumor was less than 3.0 cm, the imaging tumor-nipple distance was greater than 2.0 cm and the pathological assessment showed clear margins. The cumulative incidence of local recurrence (LR), recurrence-free survival (RFS) and overall survival (OS) curves were estimated using the Kaplan-Meier method. After at least one year of follow-up, 64 patients were asked about their satisfaction with the reconstructed breast(s). RESULTS: At a mean follow-up time of 43.5 months, seven cases of LR (4.4%), four distant metastases (2.6%) and five deaths (3.3%) were recorded. The five-year actuarial LR-free survival, RFS and OS were 97.6%, 98.3% and 98.3%, respectively. No cases of nipple-areolar complex recurrence were reported. Forty-one patients (64%) indicated a high level of satisfaction with the reconstructed breasts. CONCLUSIONS: Mammary adenectomy is a safe and efficacious procedure for selected patients with early-infiltrating breast carcinoma and results in a high rate of patient satisfaction with the reconstructed breasts.

BREAST CANCER SURVIVAL IN A BRAZILIAN CANCER CENTER: A COHORT STUDY OF 5, 095 PATIENTS / Sobrevida do câncer de mama em um centro de câncer brasileiro: um estudo de coorte de 5. 095 pacientes

Objectives: To describe the age group, clinical stage at diagnosis, treatment, and survival rates of breast cancer patients treated in a Brazilian specialized Cancer Center. Method: A hospital-based retrospective cohort study is presented herein, on women with breast cancer diagnosed between January 1, 2000 and December 31, 2012. Data were extracted from the Hospital Cancer Registry of the A.C.Camargo Cancer Center. Data on age group, histology of the tumor, TNM classification, clinical stage and treatments were described in absolute and relative frequencies for three periods. Survival curves were estimated with the Kaplan-Meier estimator. Hazard ratio (HR) and 95% confidence interval (95%CI) were calculated for all variables. Results: A total of 5,095 female breast cancer patients were identified, with most stages classified as I and II (60%). The overall survival was 82.7% for the period of 2000­2004, and 89.9% for 2010­2012 (p<0.001). Patients with invasive ductal carcinoma, who were treated with surgery and hormonal therapy, showed a reduction in the risk of death in the most recent period HRadj=0.42 (95%CI 0.34­0.53) (2010­2012). Conclusions: Early stage diagnosis and combined treatment (including HT) are predictive prognostic factors for high survival rates in patients with invasive breast cancer. Specialized cancer centers can provide valuable indications regarding cancer control policies, evaluating overall survival for breast cancer and its associated prognosis.

Objetivos: Descrever as faixas etárias, estadiamento clínico ao diagnóstico, tratamento e sobrevida global das pacientes com câncer de mama tratadas em um centro de câncer brasileiro. Método: Estudo de uma coorte retrospectiva de base hospitalar, com mulheres diagnosticadas de câncer de mama entre 1º de janeiro de 2000 e 31 de dezembro de 2012. Os dados foram extraídos do Registro Hospitalar de Câncer do A. C. Camargo Cancer Center. Faixa etária, tipo histológico, classificação TNM, estadiamento clínico e tratamento foram descritos em frequência absoluta e relativa estratificados em três períodos. As curvas de sobrevida global foram estimadas pelo método de Kaplan-Meier. A Hazard ratio (HR) com intervalo de confiança de 95% foram calculados para todas as variáveis. Resultados: O total de 5.095 pacientes mulheres com câncer de mama foi identificado, a maioria era estágio inicial 60% (I e II). A sobrevida global foi de 82,7% para o período de 2000­2004 e 89,9% para 2010­2012 (p<0,001). Pacientes com carcinoma ductal invasivo que foram tratadas com cirurgia e hormonioterapia, mostraram redução do risco de morte no período mais recente HRaj=0,42 (0,34­0,53 em 2010­2012). Conclusões: Diagnóstico precoce e tratamento combinado (incluindo hormonioterapia) são fatores prognósticos preditivos para altas taxas de sobrevida em pacientes com câncer de mama invasivo. Centros especializados em câncer podem prover informações valiosas sobre as políticas de controle do câncer, avaliando a sobrevida global do câncer de mama e fatores associados ao prognóstico.

Linfonodo sentinela em câncer de mama: situações especiais na prática clínica / Sentinel lymph node biopsy in breast cancer: special situations in clinical practice

A biópsia do linfonodo sentinela já é um procedimento consagrado tanto em nivel nacional quanto internacional para a avaliação da axila de pacientes com câncer de mama diagnosticado na sua fase inicial. Porém, ainda existem algumas situações que geram dúvidas tanto sobre a melhor abordagem, quanto o tratamento. Nos últimos anos, temos observado um crescente interesse em relação à biópsia do linfonodo sentinela (BLS) e na maneira como urilizá-la em algumas situações especiais como no carcinoma ductal in situ (CDIS), quando há drenagem para a mamária interna, câncer de mama na gravidez, mastectomia profilática e tratamento quimioterápico sistêmico pré-operatório (quimioterapia sistêmica neoadjuvante - QT neo). Existem diversos estudos prospectivos em andamento para se estabelecer a condura ideal. Porém, enquanto os resultados não são publicados, necessitamos nos atualizar com relação à melhor maneira de abordá-los. Este artigo tentou apresentar, de maneira clara e resumida, o que há de mais recente publicado em relação à essas situações.

The sentinel lymph node biopsy is an accepted procedure at a national and international level to study the axillary status of patients with early-stage breast cancer. However there are some special situations that create some doubts about the better way to diagnostic and to threat it. In the last years we have seen a greatest interest in sentinel lymph node biopsy (SINB) and in the manner how to use it in some special situations like ductal carcinoma in situ, when there is migration to internal mammary lymph nodes, breast cancer and pregnancy, during prophylactic mastectomy and systemic therapy before surgery (preoperative chemotherapy). There are several prospective studies going on, with the intent to determine the ideal treatment for these special situations. While these results are not published, we must be aware of the better way to treat them. This article tries to show, in an easy and clear way, what have been published recently about these situations.

Câncer de mama na gestação: relato de casos / Pregnancy-associated breast cancer: case reports

O câncer de mama na gestação vem se tomando uma realidade na medida em que a idade da primeira gestação das mulheres aumenta. Aproximadamente 3% dos tumores de mama são diagnosticados em mulheres grávidas entre os 23 e os 47 anos de idade (media de 33 anos). Por definição, o câncer de mama associado à gestação é todo câncer de mama diagnosticado durante a mesma ou até um ano após o parto. Em geral, o câncer de mama na gestação apresenta-se de forma avançada devido principalmente ao atraso no diagnóstico e no tratamento do que devido às características histológicas dos tumores. Na literatura, ainda não há um consenso sobre a melhor estratégia terapêutica a ser usada. São apresentados aqui três casos de câncer de mama durante a gestação bem como uma análise sobre aspectos patológicos, diagnósticos e terapêuticos, com base na experiência dos autores e no que há de mais recente na literatura.

Pregnancy-associated breast cancer is becoming a reality since women delay childbearing. Approximately 3% of breast cancers are diagnosed in pregnant woman between 23 to 47years (mean age 33 years). It is defined as any breast carcinoma diagnosed during pregnancy or during the first postpartum year. The pregnancy-associated breast cancer usually presents as an advanced stage, in part because of delay on diagnostic and treatment, than histological characteristics of the breast cancer. There is no consensus about the better treatment option that should being used. We report here three cases of pregnancy-associated breast cancer and discuss some clinical, histopathological, diagnostic and therapeutic aspects, showing our experience and the more recent we found in literature.

Intracystic papillary carcinoma of the breast: risks in diagnostic, staging and treatment

Intracystic papillary carcinoma (IPC) of the breast is a rare form of breast in situ carcinoma that comprises 0.5-2% of all breast tumors. IPC of the breast occurs in women around the sixth decade of life and presents an injury of great dimensions, more frequently retroareolar. Clinical and radiological findings can be confused with advanced-staged invading carcinomas (T2 or T3), leading to unnecessarily aggressive treatment. The correlation of clinical, radiological and anatomopathological findings is necessary for a correct diagnosis. We present two cases of IPC and discuss diagnostic characteristics.
