Résumé
Objetivo: Apresentar a atualização das recomendações do Colégio Brasileiro de Radiologia e Diagnóstico por Imagem, da Sociedade Brasileira de Mastologia e da Federação Brasileira das Associações de Ginecologia e Obstetrícia para o rastreamento do câncer de mama no Brasil. Materiais e Métodos: Foram feitas buscas das evidências científicas publicadas nas bases Medline, EMBASE, Cochrane Library, EBSCO, CINAHL e Lilacs, entre janeiro de 2012 e julho de 2022. As recomendações foram baseadas nessas evidências, mediante consenso da comissão de especialistas das três entidades. Recomendações: O rastreamento mamográfico anual é recomendado para as mulheres de risco habitual entre 40 e 74 anos. Acima de 75 anos, deve ser reservado para as que tenham expectativa de vida maior que sete anos. Mulheres com risco maior que o habitual, entre elas as com mamas densas, com história pessoal de hiperplasia lobular atípica, carcinoma lobular in situ clássico, hiperplasia ductal atípica, tratamento de câncer de mama ou de irradiação no tórax antes dos 30 anos ou, ainda, portadoras de mutação genética ou com forte história familiar, beneficiam-se do rastreamento complementar, sendo consideradas de forma individualizada. A tomossíntese é uma evolução da mamografia e deve ser considerada no rastreamento, sempre que acessível e disponível. (AU)
Objective: To present the update of the recommendations of the Brazilian College of Radiology, the Brazilian Society of Mastology and the Brazilian Federation of Gynecology and Obstetrics Associations for breast cancer screening in Brazil. Materials and Methods: Scientific evidence published in Medline, Embase, Cochrane Library, Ebsco, Cinahl and Lilacs between January 2012 and July 2022 was searched. Recommendations were based on this evidence, by consensus of the expert committee of the three entities. Recommendations: Annual mammographic screening is recommended for women aged between 40 and 74 years old. Above 75 years should be reserved for those with a life expectancy greater than seven years. Women at higher than usual risk, including those with dense breasts, a personal history of atypical lobular hyperplasia, classic lobular carcinoma in situ, atypical ductal hyperplasia, treatment for breast câncer, chest irradiation before age 30, carriers of genetic mutation or with a strong family history, benefit from complementary screening, being considered individually. Tomosynthesis is an evolution of mammography and should be considered in screening, whenever accessible and available. (AU)

Abstract Objective: To present an update of the recommendations of the Brazilian College of Radiology and Diagnostic Imaging, the Brazilian Society of Mastology, and the Brazilian Federation of Gynecology and Obstetrics Associations for breast cancer screening in Brazil. Materials and Methods: Scientific evidence published between January 2012 and July 2022 was gathered from the following databases: Medline (PubMed); Excerpta Medica (Embase); Cochrane Library; Ebsco; Cumulative Index to Nursing and Allied Health Literature (Cinahl); and Latin-American and Caribbean Health Sciences Literature (Lilacs). Recommendations were based on that evidence and were arrived at by consensus of a joint committee of experts from the three entities. Recommendations: Annual mammographic screening is recommended for women between 40 and 74 years of age. For women at or above the age of 75, screening should be reserved for those with a life expectancy greater than seven years. Women at higher than average risk are considered by category: those with dense breasts; those with a personal history of atypical lobular hyperplasia, classical lobular carcinoma in situ, or atypical ductal hyperplasia; those previously treated for breast cancer; those having undergone thoracic radiotherapy before age 30; and those with a relevant genetic mutation or a strong family history. The benefits of complementary screening are also addressed according to the subcategories above. The use of tomosynthesis, which is an evolved form of mammography, should be considered in screening, whenever accessible and available.

Résumé
OBJECTIVE: To assess the influence of skeletal muscle mass on ventilatory and hemodynamic variables during exercise in patients with chronic heart failure (CHF). METHODS: Twenty-five male patients underwent maximum cardiopulmonary exercise testing on a treadmill with a ramp protocol and measurement of the skeletal muscle mass of their thighs by using magnetic resonance imaging. The clinically stable, noncachectic patients were assessed and compared with 14 healthy individuals (S) paired by age and body mass index, who underwent the same examinations. RESULTS: Similar values of skeletal muscle mass were found in both groups (CHF group: 3863 ± 874 g; S group: 3743 ± 540 g; p = 0.32). Significant correlations of oxygen consumption in the anaerobic threshold (CHF: r = 0.39; P= 0.02 and S: r = 0.14; P = 0.31) and of oxygen pulse also in the anaerobic threshold (CHF: r = 0.49; P = 0.01 and S: r =0.12; P = 0.36) were found only in the group of patients with chronic heart failure. CONCLUSION: The results obtained indicate that skeletal muscle mass may influence the capacity of patients with CHF to withstand submaximal effort, due to limitations in their physical condition, even maintaining a value similar to that of healthy individuals. This suggests qualitative changes in the musculature

Foram realizados exames de ressonância magnética (RM) em 16 pacientes com câncer de mama localmente avançado pré e pós-quimioterapia, para se avaliar a resposta à quimioterapia neoadjuvante. Foram avaliados pela RM o volume tumoral pré e pós-quimioterapia, o maior diâmetro do tumor residual, o volume tumoral calculado com e sem o mecanismo de subtração e a classificação em relação à localização do tumor residual. Os achados da RM foram comparados aos da Anatomia Patológica. Verificou-se que a RM permite a avaliação de modo objetivo do volume tumoral pré e pósquimioterapia redutora, que há concordância entre os valores dos maiores diâmetros tumorais, que há correlação entre os volumes tumorais medidos com e sem o mecanismo de subtração e que não há concordância entre a classificação em relação à localização do tumor residual na RM e patologia.
Sixteen patients with locally advanced breast cancer were submitted to magnetic resonance imaging (MRI) pre- and post-chemotherapy, to evaluate the response to neoadjuvant chemotherapy. The parameters studied by MRI were tumoral volume pre- and post-chemotherapy, greater diameter of the residual tumor, tumoral volume calculated with and without subtraction and classification related to the residual tumor location. MRI findings were compared to those found on Pathology. MRI allowed an objective assessment of pre- and post-chemotherapy tumoral volume, demonstrated concordance between the largest tumoral diameters, showed correlation among tumoral volumes measured with and without subtraction and verified no concordance between MRI and pathologic classification by residual tumor location.
