The present invention provides a method of identifying origin of a metastasis of unknown origin by obtaining a sample containing metastatic cells; measuring Biomarkers associated with at least two different carcinomas; combining the data from the Biomarkers into an algorithm where the algorithm normalizes the Biomarkers against a reference; and imposes a cut-off which optimizes sensitivity and specificity of each Biomarker, weights the prevalence of the carcinomas and selects a tissue of origin determining origin based on highest probability determined by the algorithm or determining that the carcinoma is not derived from a particular set of carcinomas; and optionally measuring Biomarkers specific for one or more additional different carcinoma, and repeating the steps for additional Biomarkers.

L'invention concerne une méthode d'identification de l'origine d'une métastase d'origine inconnue qui consiste à : obtenir un prélèvement contenant des cellules métastatiques; mesurer les biomarqueurs associés à au moins deux carcinomes différents; combiner les données des biomarqueurs dans un algorithme qui normalise les biomarqueurs avec une référence et impose une limite d'exclusion qui optimise la sensibilité et la spécificité de chaque biomarqueur, qui pondère la prévalence des carcinomes et sélectionne un tissu d'origine déterminant l'origine sur la base de la probabilité la plus élevée définie par l'algorithme, ou déterminant que le carcinome ne provient pas d'un groupe particulier de carcinomes; et éventuellement, mesurer les biomarqueurs spécifiques pour au moins un carcinome différent supplémentaire, et répéter ces opérations pour chaque biomarqueur supplémentaire.
