The mPTCL seemed to recapitulate the poor prognostic Th2‐like GATA3 subgroup of PTCL, owing to common GATA3 and Th2‐associated gene expression, MYC activation, and genome instability (Iqbal et al, 2010, 2014; Wang et al, 2014a; Manso et al, 2016; Amador et al, 2019; Watatani et al, 2019). This evidence concerns the gene MYC and mature T-cell and NK-cell non-Hodgkin lymphoma.
