Adjunctive ultrasonography in breast cancer screening
Mené sur 72 998 participantes asymptomatiques (âge : 40 à 49 ans), cet essai japonais évalue, du point de vue de la sensibilité, de la spécificité, du taux de détection de cancer du sein et du stade au diagnostic, l'intérêt d'ajouter une échographie mammaire à une mammographie
The sensitivity and specificity of mammography are limited in highly fibroglandular breasts. Digital mammography provides increased sensitivity in young women and those with moderately dense breasts,1 and digital three-dimensional mammography promises further improvement.2–4 For women with the densest breasts, however, radiography is unlikely to be the optimum solution. MRI, although not affected by breast density, is expensive and access is often limited. Ultrasonography is attractive for breast cancer screening because, likewise, it is not impaired by breast density, and it avoids the use of ionising radiation and the need for breast compression.
