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 a linear discrimination analysis where the linear discrimination analysis 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 linear discrimination analysis 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.

La présente invention concerne un procédé d'identification de l'origine d'une métastase d'origine inconnue par l'obtention d'un échantillon contenant des cellules métastatiques; la mesure des biomarqueurs associés à au moins deux carcinomes différents; la combinaison des données des biomarqueurs dans une analyse discriminatoire linéaire où l'analyse discriminatoire linéaire normalise les biomarqueurs par rapport à une référence; et impose une coupure qui optimise la sensibilité et la spécificité de chaque biomarqueur, pondère la prévalence des carcinomes et sélectionne un tissu d'origine déterminant l'origine sur la base de la probabilité la plus élevée déterminée par l'analyse discriminatoire linéaire ou déterminant que le carcinome ne provient pas d'un ensemble de carcinomes; et la mesure éventuelle des biomarqueurs spécifiques pour un ou plusieurs carcinomes différents, et la répétition des étapes pour des biomarqueurs supplémentaires.
