EIF4E and neoplasm: Although NB is biologically very heterogenous, a difference in eIF4AI and eIF4E expression was absent in this cohort when stratified for adrenal and non-adrenal localization (p = 0.285 and p = 1.000, respectively), as well as for the MYCN amplification status (p = 0.689 and p = 0.717, respectively) of the tumor.
