CA 2535805

Provided are methods for the rapid detection of ovarian cancer. The methods employ a multiplex immunoassay to detect levels of two or more of the markers EGF, G-CSF, IL-6, IL-8, CA-125; VEGF, MCP-1, anti-IL6, anti-IL8, anti CA-125, anti-c-myc, anti-p53, anti-CEA, anti-CA 15-3, anti-MUC-1, anti-survivin, anti- bHCG, anti-osteopontin, anti-PDGF, anti-Her2/neu, anti-Akt1, anti-cytokeratin 19, cytokeratin 19, EGFR, CEA, kallikrein-8, M-CSF, FasL, ErB2 and Her2/neu in a sample of the patient~s blood, where the presence of abnormal levels of two or more of the markers indicates the presence of ovarian cancer in the patient. An array also is provided to quantitate levels of these markers in a patient~s blood. Also provided is a method of predicting onset of clinical ovarian cancer comprising determining the change in concentration over time of two or more of anti-Her2/neu, anti-MUC-1, anti-c-my, anti-p53, anti-CA-125, anti-CEA, anti-CA 72-4, anti-PDGFR.alpha., IFN.gamma., IL-6, IL-10, TNF.alpha., MIP-1.alpha.m MIP-1.beta., EGFR and Her2/neu in a patient~s blood.

La présente invention se rapporte à des méthodes permettant une détection rapide d'un cancer des ovaires. Ces méthodes mettent en oeuvre un immuno-essai multiplex pour détecter les niveaux d'au moins deux des marqueurs EGF, G-CSF, IL-6, IL-8, CA-125, VEGF, MCP-1, anti-IL6, anti-IL8, anti CA-125, anti-c-myc, anti-p53, anti-CEA, anti-CA 15-3, anti-MUC-1, anti-survivine, anti-bHCG, anti-ostéopontine, anti-PDGF, anti-Her2/neu, anti-Akt1, anti-cytokératine 19, cytokératine 19, EGFR, CEA, kallikréine-8, M-CSF, FasL, ErB2 et Her2/neu, dans un échantillon de sang prélévé chez une patiente, la présence de niveaux anormaux d'au moins deux de ces marqueurs indiquant la présence d'un cancer des ovaires chez la patiente. L'invention se rapporte également à une matrice permettant de quantifier les niveaux de ces marqueurs dans le sang d'une patiente. L'invention se rapporte également à une méthode permettant de prédire l'apparition d'un cancer clinique des ovaires, qui consiste à déterminer, dans le sang d'une patiente, la modification dans le temps de la concentration d'au moins deux des marqueurs anti-Her2/neu, anti-MUC-1, anti-c-my, anti-p53, anti-CA-125, anti-CEA, anti-CA 72-4, anti-PDGFR.alpha., IFNy, IL-6, IL-10, TNF.alpha., MIP-1.alpha.m, MIP-1.beta., EGFR et Her2/neu.
