Résumé
Cinq principaux sous-types moléculaires ont été identifiés à partir des données des puces d’expression d’analyse des carcinomes infiltrants de type canalaire: luminal A, luminal B, ERBB2, basal-like et normal-like. Les carcinomes basal-like sont caractérisés par l’absence d’expression des récepteurs aux estrogènes et à la progestérone et de ERBB2 et sont donc de ce fait »triples négatifs«. Toutefois, les carcinomes triples négatifs ne partagent pas tous les critères diagnostiques des basal-like et représentent un groupe plus large de tumeurs. Or, de nouvelles possibilités thérapeutiques basées sur une meilleure compréhension des caractéristiques biologiques des carcinomes basal-like sont en développement pour adapter la prise en charge thérapeutique des patientes. Comme cette entité a été identifiée à partir des données des puces d’expression transcriptomique inaccessible en routine et que de nouvelles avancées thérapeutiques de ces tumeurs deviennent disponibles, il est nécessaire de pouvoir les identifier en pratique clinique de façon simple et reproductible.
