Since the failure to find significant differences was most likely due to small numbers in the various subsets, we combined all cancers according to the number of alterations, including PTEN deletion and amplification of any of HER2, MYC, and CCND1. In this combined analysis, we found a shortened survival for patients with cancers harboring alterations in 2 or more of these genes as compared to tumors with no or one alteration (p = 0.0002, Fig. 5d). Here, MYC is linked to cancer.
