In light of our results showing high expression of MEG3 in breast stromal tissue, and uncertainty that measured MEG3 expression in the normal-like subgroup is representative of the primary tumor, we omitted NL breast tumors from the survival analysis (Elloumi et al., 2011; Prat and Perou, 2011; Yersal and Barutca, 2014). The gene discussed is MEG3; the disease is breast neoplasm.
