The two datasets obtained from GEO are GSE58215 and GSE19783; out of 283 tumor samples in GSE58215 dataset, we counted 121 luminal A, 69 luminal B, 36 triple negative/basal-like, and 32 ERBB2/HER2+ subtype patients; in GSE19783 dataset out of 101 tumor samples, we counted 41 luminal A, 12 luminal B, 15 triple negative/basal-like, and 17 ERBB2/HER2+ subtype patients. This evidence concerns the gene ERBB2 and neoplasm.
