s’il est réalisable ; l’irradiation est indiquée dans 
tous les cas. À l’issue de cette radiothérapie, la 
reprise du traitement à base de trastuzumab semble 
un choix raisonnable, étant donné l’augmentation 
de la perméabilité de la barrière hémato-méningée 
par l’irradiation et le faible taux de réponse rapporté 
avec le lapatinib. Quelques rapports anecdotiques 
ont décrit l’injection intrathécale de trastuzumab. 
Enfin, il n’existe actuellement aucune donnée 
permettant d’isoler un groupe de patientes à 
risque qui pourrait bénéficier d’une radiothérapie 
prophylactique.  ■
