OBJETIVO<\/strong><\/p>\n

Nesse estudo, os autores procuraram determinar a rela\u00e7\u00e3o entre o grau de edema da mama em imagens ponderadas em T2 e o progn\u00f3stico de c\u00e2ncer de mama em pacientes tratadas com quimioterapia neoadjuvante.<\/p>\n

MATERIAL E M\u00c9TODO<\/strong><\/p>\n

Resson\u00e2ncia magn\u00e9tica de 408 mulheres tratadas com quimioterapia neoadjuvante obtidas entre janeiro de 2011 e dezembro de 2018 foram revisadas retrospectivamente. Edema de mama foi graduado de 1- 4 (1=aus\u00eancia de edema, 2= edema peritumoral, 3=edema pr\u00e9-peitoral, 4 edema subcut\u00e2neo suspeito de carcinoma inflamat\u00f3rio oculto).<\/p>\n

RESULTADO<\/strong><\/p>\n

Diferen\u00e7as entre o grau de edema da mama na sobrevida livre de progress\u00e3o e na sobrevida global foram determinadas usando log-rank test<\/em>. Diferen\u00e7as estat\u00edscas significativas na sobrevida livre de doen\u00e7a estavam presentes na gradua\u00e7\u00e3o de 4 versus 1, 5 versus 1, 5 versus 2 e 5 versus 3. As taxas na sobrevida global foram menores nos edemas com gradua\u00e7\u00e3o de 4 e 5 versus graus de 1 -3.<\/p>\n

CONCLUS\u00c3O<\/strong><\/p>\n

Os autores concluiram que o progn\u00f3stico de pacientes tratadas com quimioterapia neoadjuvante estava relacionado ao grau de edema.<\/p>\n

Rastreio do c\u00e2ncer de mama com protocolo abreviado de resson\u00e2ncia magn\u00e9tica da mama: an\u00e1lise de resultados de 3 anos.<\/strong><\/span><\/h5>\n

Kwon, M., Choi, J. S., Won, H., Ko, E. Y., Ko, E. S., Park, K. W., & Han, B. (2021). Radiology,299<\/em>(1), 73-83. doi:10.1148\/radiol.2021202927<\/p>\n

https:\/\/pubs.rsna.org\/doi\/10.1148\/radiol.2021202927<\/a><\/p>\n

OBJETIVO<\/strong><\/p>\n

Neste estudo, os autores procuraram determinar o desempenho diagn\u00f3stico do protocolo abreviado da resson\u00e2ncia magn\u00e9tica e comparar os resultados de cada ano nos tr\u00eas anos consecutivos.<\/p>\n

MATERIAL E M\u00c9TODO<\/strong><\/p>\n

Entre setembro de 2015 e agosto de 2018, 1.975 mulheres foram submetidas a 3.037 exames de resson\u00e2ncia magn\u00e9tica com protocolo abreviado, que inclu\u00edram sequ\u00eancias ponderadas em T2 e estudo din\u00e2mico (ap\u00f3s contraste).<\/p>\n

RESULTADO<\/strong><\/p>\n

N\u00e3o ocorreram diferen\u00e7as estatisticamente significativas, entre anos consecutivos, para taxa de detec\u00e7\u00e3o de c\u00e2ncer (6,9 -10,7 por 1.000 exames de rastreamento), sensibilidade (70-85%), especificidade (93,5-94,1%), valor preditivo positivo para reconvoca\u00e7\u00e3o (9,7-15,6%), valor preditivo positivo para bi\u00f3psia (31,6-63,2%), taxa de interpreta\u00e7\u00e3o anormal e taxa de c\u00e2ncer de intervalo. Todos os c\u00e2nceres perdidos eram de doen\u00e7a invasiva em est\u00e1gio inicial, sem envolvimento nodal. Todos os c\u00e2nceres perdidos eram c\u00e2ncer invasivo sem comprometimento linfonodal e eram menores que os c\u00e2nceres detectados.<\/p>\n

CONCLUS\u00c3O<\/strong><\/p>\n

Os autores conclu\u00edram que n\u00e3o houve diferen\u00e7a significativa nos resultados do protocolo abreviado de resson\u00e2ncia magn\u00e9tica ao longo de tr\u00eas anos consecutivos.<\/p>\n

OBJETIVO<\/strong><\/p>\n

Neste estudo, os autores procuraram comparar os indicadores de desempenho entre a primeira e a segunda triagem por resson\u00e2ncia magn\u00e9tica no ensaio Dense Tissue and Early Breast Neoplasm Screening (DENSE) realizado entre dezembro de 2011 e janeiro de 2016.<\/p>\n

MATERIAL E M\u00c9TODO<\/strong><\/p>\n

Este ensaio foi associado ao programa populacional de mamografia bienal holand\u00eas, para mulheres com idades entre 50-75 anos.<\/p>\n

Mulheres com mamas densas e mamografia negativa, foram submetidas a resson\u00e2ncia magn\u00e9tica.<\/p>\n

Uma segunda resson\u00e2ncia era realizada nas mulheres cuja mamografia fosse negativa ap\u00f3s a primeira resson\u00e2ncia. 3.400 mulheres foram submetidas a uma segunda resson\u00e2ncia magn\u00e9tica.<\/p>\n

RESULTADO\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <\/strong><\/p>\n

A taxa de falsos positivos na segundo exame por resson\u00e2ncia foi de 26,3 por 1.000 exames em compara\u00e7\u00e3o com 79,8 no primeiro exame.<\/p>\n

A taxa de detec\u00e7\u00e3o de c\u00e2ncer na segunda resson\u00e2ncia magn\u00e9tica foi de 5,8 por 1.000 exames, em compara\u00e7\u00e3o com 16,5 na primeira.<\/p>\n

Os valores preditivos positivos para reconvoca\u00e7\u00e3o e bi\u00f3psia foram compar\u00e1veis \u200b\u200bentre os dois exames.<\/p>\n

CONCLUS\u00c3O<\/strong><\/p>\n

Os autores conclu\u00edram que as baixas taxas de detec\u00e7\u00e3o de c\u00e2ncer e de resultados falsos positivos eram provavelmente devido \u00e0 disponibilidade de exame pr\u00e9vio de resson\u00e2ncia magn\u00e9tica e ao menor n\u00famero de c\u00e2nceres prevalentes.<\/p>\n","protected":false},"excerpt":{"rendered":"[embedyt] https:\/\/www.youtube.com\/watch?v=bleY5hPzIvw[\/embedyt]   A avalia\u00e7\u00e3o dos achados de edema na mama em imagens de resson\u00e2ncia […]","protected":false},"author":3,"featured_media":3018,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_bbp_topic_count":0,"_bbp_reply_count":0,"_bbp_total_topic_count":0,"_bbp_total_reply_count":0,"_bbp_voice_count":0,"_bbp_anonymous_reply_count":0,"_bbp_topic_count_hidden":0,"_bbp_reply_count_hidden":0,"_bbp_forum_subforum_count":0,"footnotes":""},"categories":[207],"tags":[],"class_list":["post-14173","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-sem-categoria"],"yoast_head":"\nWhat's new in Breast Imaging (Portuguese) - June 2021 - ACORE<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/staging-hub.acoredu.com\/13998\/\" \/>\n<meta property=\"og:locale\" content=\"pt_PT\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"What's new in Breast Imaging (Portuguese) - June 2021 - ACORE\" \/>\n<meta property=\"og:description\" content=\"[embedyt] https:\/\/www.youtube.com\/watch?v=bleY5hPzIvw[\/embedyt]   A avalia\u00e7\u00e3o dos achados de edema na mama em imagens de resson\u00e2ncia […]\" \/>\n<meta property=\"og:url\" content=\"https:\/\/staging-hub.acoredu.com\/13998\/\" \/>\n<meta property=\"og:site_name\" content=\"ACORE\" \/>\n<meta property=\"article:published_time\" content=\"2021-06-16T08:18:42+00:00\" \/>\n<meta property=\"og:image\" content=\"https:\/\/staging-hub.acoredu.com\/wp-content\/uploads\/2020\/07\/female-hands-joined-in-circle-holding-pink-ribbons-RCN683A-scaled.jpg\" \/>\n\t<meta property=\"og:image:width\" content=\"2560\" \/>\n\t<meta property=\"og:image:height\" content=\"2560\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/jpeg\" \/>\n<meta name=\"author\" content=\"Abdelrahman\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:label1\" content=\"Escrito por\" \/>\n\t<meta name=\"twitter:data1\" content=\"Abdelrahman\" \/>\n\t<meta name=\"twitter:label2\" content=\"Tempo estimado de leitura\" \/>\n\t<meta name=\"twitter:data2\" content=\"3 minutos\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"WebPage\",\"@id\":\"https:\/\/staging-hub.acoredu.com\/13998\/\",\"url\":\"https:\/\/staging-hub.acoredu.com\/13998\/\",\"name\":\"What's new in Breast Imaging (Portuguese) - June 2021 - ACORE\",\"isPartOf\":{\"@id\":\"https:\/\/staging-hub.acoredu.com\/#website\"},\"primaryImageOfPage\":{\"@id\":\"https:\/\/staging-hub.acoredu.com\/13998\/#primaryimage\"},\"image\":{\"@id\":\"https:\/\/staging-hub.acoredu.com\/13998\/#primaryimage\"},\"thumbnailUrl\":\"https:\/\/staging-hub.acoredu.com\/wp-content\/uploads\/2020\/07\/female-hands-joined-in-circle-holding-pink-ribbons-RCN683A-scaled.jpg\",\"datePublished\":\"2021-06-16T08:18:42+00:00\",\"author\":{\"@id\":\"https:\/\/staging-hub.acoredu.com\/#\/schema\/person\/75293c6e4870f3aa293e1394c53df6b7\"},\"breadcrumb\":{\"@id\":\"https:\/\/staging-hub.acoredu.com\/13998\/#breadcrumb\"},\"inLanguage\":\"pt-PT\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/staging-hub.acoredu.com\/13998\/\"]}]},{\"@type\":\"ImageObject\",\"inLanguage\":\"pt-PT\",\"@id\":\"https:\/\/staging-hub.acoredu.com\/13998\/#primaryimage\",\"url\":\"https:\/\/staging-hub.acoredu.com\/wp-content\/uploads\/2020\/07\/female-hands-joined-in-circle-holding-pink-ribbons-RCN683A-scaled.jpg\",\"contentUrl\":\"https:\/\/staging-hub.acoredu.com\/wp-content\/uploads\/2020\/07\/female-hands-joined-in-circle-holding-pink-ribbons-RCN683A-scaled.jpg\",\"width\":2560,\"height\":2560,\"caption\":\"Breast Cancer.
