The present invention relates to genetic markers whose expression is correlated with breast cancer. Specifically, the invention provides sets of markers whose expression patterns can be used to differentiate clinical conditions associated with breast cancer, such as the presence or absence of the estrogen receptor ESR1, and BRCA1 and sporadic tumors, and to provide information on the likelihood of tumor distant metastases within five years of initial diagnosis. The invention relates to methods of using these markers to distinguish these conditions. The invention also provides methods of classifying and treating patients based on prognosis. The invention also relates to kits containing ready-to-use microarrays and computer software for data analysis using the diagnostic, prognostic and statistical methods disclosed herein.

La présente invention concerne des marqueurs génétiques, dont l'expression est corrélée au cancer du sein. Plus particulièrement, cette invention a trait à des ensembles de marqueurs, dont les modèles d'expression peuvent être utilisés pour différencier des conditions cliniques liées au cancer du sein, telles que la présence ou l'absence du récepteur d'oestrogènes <I>ESR1</I> et <I>BRCA1</I> et aux tumeurs sporadiques, et pour fournir des informations sur la probabilité de métastases distantes tumorales en l'espace de 5 années à partir du diagnostic initial. Ladite invention a également pour objet des méthodes d'utilisation de ces marqueurs afin de distinguer ces conditions, des méthodes de classification et de traitement de patients en fonction du pronostic, ainsi que des kits contenant des microréseaux prêts à l'emploi et un logiciel informatique d'analyse de données, au moyen des méthodes diagnostiques, pronostiques et statistiques de cette invention.
