Consistent with our institutional findings, ERBB2 expression (https://www.proteinatlas.org/ENSG00000141736-ERBB2/cancer/stomach+cancer#STAD_TCGA) and TP53 expression (https://www.proteinatlas.org/ENSG00000141510-TP53/cancer/stomach+cancer#STAD_TCGA) were not significantly associated with overall survival for GAC in that dataset. Here, ERBB2 is linked to medical procedure.
