Neoplasias mamárias
Valor preditivo
Abstract in Portuguese
Foram avaliados 507 casos de calcificações quanto as suas características (densidade, morfologia, distribuição, extensão e número) e associação com o câncer de mama.De acordo com os valores preditivos positivos de cada tipo de calcificação elas foram categorizadas pelo sistema BI-RADS em subcategorias 4A (2 a 10%), 4B (10,1 a 30%) e 4C (30,1 a 70,0%) e categoria 5 (acima de 70%). Todas as características se mostraram importantes na diferenciação das calcificações em benignas e malignas, em menor grau a densidade e em maior grau a morfologia e a distribuição. A distribuição linear ou segmentar, e a morfologia pleomorfa ou linear apresentaram as mais altas taxas de malignidade

Abstract in English
Five hundred and seven cases of calcificações had been evaluated about its characteristics (density, morphology, distribution, extension and number) and association with the breast cancer. Using the VPP of each type of calcifications they had been categorized by the BI-RADS system in categories 4Â (2 to10%), 4B (10,1 to 30%) and 4C (30,1 to 70.0%) and category 5 (above 70%). All the characteristics had shown importance in the differentiation of the calcificações in benign and malignant, in lesser degree the density and bigger degree the morphology and distribuition. A linear or segmentary distribuition, and the pleomorfic or linear morphology had presented the highest taxes of malignidade
