Abstract: The present invention is concerned with a method for diagnosing breast cancer in a subject comprising the steps of determining in a sample of a subject suspected to be afflicted with said breast cancer the amount of at least one miRNA or the amounts of at least the miRNAs of a combination of miRNAs selected from the group consisting of: (i) miR-801, (ii) miR-801 and miR-148b, (iii) miR-801 and miR-376c, (iv) miR-801 and miR-409-3p, (v) miR-801, miR-376c and miR-148b, (vi) miR-801, miR-409-3p and miR-376c, (vii) miR-801, miR-409-3p and miR-148b, miR-801, miR-376c, miR-409-3p and miR-148b, (ix) miR-148b, (x) miR-409-3p, (xi) miR-376c, (xii) miR-376c and miR-409-3p, (xiii) miR-148b and miR-376c, (xiv) miR-148b and miR-409-3p, (xv) miR-148b, miR-376c and miR-409-3p, (xvi) miR-127-3p, (xvii) miR-148b, (xvii) miR-376a, (xix) miR-376c, (xx) miR-409-3p, (xxi) miR-652, (xxii) miR-127-3p, miR-148b, miR-376a, miR-376c, miR-409-3p, miR-652, and miR-801, (xxiii) miR-127-3p, miR-148b, miR-652, and miR-801, (xxiv) miR-376a,

Abstract: The present invention is directed to methods for diagnosing breast cancer, metastasizing breast cancer, or for determining the CTC status in a subject. Moreover, the present invention is concerned with devices and kits for carrying methods of the invention. The methods comprise determining in a sample of a subject suspected to be afflicted with breast cancer the amount of at least one miRNA selected from a recited list of miRNAs, followed by comparing the amount with one or more references, whereby breast cancer is to be diagnosed.
