Although the overlap of Oncomine and InVision was small (7 genes included in both assays), which is expected since InVision was designed for NSCLC, amongst those overlapping genes were genes frequently altered or implicated in the pathogenesis of mBC (PIK3CA, TP53, ESR1, ERBB2) [3]. This evidence concerns the gene ESR1 and non-small cell lung carcinoma.
