Breast cancer tumors were collected from the archives of the Fundación Mexicana de Fomento para la Prevención Oportuna del Cáncer de Mama, A.C., (FUCAM) after a carefully histopathological review by two training pathologist, according to the following criteria: adjuvant therapy and collection of the surgical sample without any treatment. We obtain triple negative tumors (ER-, PR- and Her2-) and tumors from other immunophenotype (ER+, PR+ or/and Her2+) by microdissection of tumoral cells for RNA extraction and hybridization on Affymetrix miRNA microarrays.
