Cellular origin of T-cell lymphomas.
Publication types: Comment ; Journal Article Publication Status: ppublish
In this issue of Blood, Iqbal et al, having compiled gene expression profiles from >300 peripheral T-cell lymphomas, expand previous findings on the diagnostic value of molecular signatures that correlate with different histological types of T-cell lymphomas. They report the discovery of 2 molecular subgroups of peripheral T-cell lymphomas, not otherwise specified (PTCL, NOS), characterized by high expression of either GATA-binding protein 3 (GATA-3) or t-box 21 (TBX21) transcription factors and corresponding target genes, with the GATA3 subgroup being associated with distinctly worse prognosis. In an independent study, Wang et al(2) also show that GATA3 expression in a subset of PTCL, NOS identifies a subgroup of patients with inferior survival.
