Frequency of the main genetic alterations observed in esophageal adenocarcinoma (EAC) (top panel) and in esophageal squamous carcinoma (ESCC) (bottom panel). The figure reports the cumulated frequency of both mutations and copy number alterations for the various genes indicated. The top panel is based on results reported by Dulak et al. [7] and Secrier et al. [9]. The bottom panel is based on data reported by Liu et al. [10], Song et al. [11], Gao et al. [12], Cheng et al. [13].
