Abstract: La présente invention concerne une composition pharmaceutique destinée à inhiber la récidive du cancer ou les métastases, et un procédé d'inhibition de la récidive du cancer ou des métastases utilisant ladite composition. Dans le cadre de l'invention, l'activité du 2-désoxy-D-glucose (2-DG) dans l'inhibition de la formation de mammosphère et de TEM a été identifiée, montrant ainsi son effet inhibiteur ‑ non connu jusqu'à présent ‑ contre la prolifération de cellules souches cancéreuses et de métastases du cancer. L'invention porte également sur l'utilisation combinée d'un agent antidiabétique à base de biguanide ou de son sel pharmaceutiquement acceptable et du 2-DG, pour inhiber les métastases du cancer et diminuer considérablement la récidive du cancer par comparaison à l'utilisation seule desdits principes actifs, entraînant ainsi un effet supérieur en termes d'inhibition des métastases et de la récidive du cancer lorsque la même dose est appliquée. Par conséquent, la composition pharmaceutique de la présente invention peut être utilisée pour entraîner des effets sensiblement supérieurs avec une quantité inférieure de chaque principe actif, réduisant ainsi les effets secondaires dus à l'utilisation de médicament en excès et à leur action pharmacologique, et pour procurer un traitement plus efficace. En outre, lorsqu'elle est utilisée avec un agent anticancéreux auquel une résistance est prouvée, un effet synergique supérieur est escompté. La composition pharmaceutique et le procédé d'inhibition de la récidive du cancer ou des métastases de la présente invention peuvent par conséquent être utilisés très avantageusement dans le traitement et la prévention de métastases ou de récidive de diverses maladies cancéreuses.
