摘要

Ectopic oncogene expression is common to T-cell acute lymphoblastic leukaemia (T-ALL). The presence of oncogene transcripts, such as LM02, LYL1, TLX1, TLX3, TALI and NKX2-1, is regarded as a defining element of a T-ALL signature (Ferrando et al, 2002; Homminga et al, 2011). This signature enables the molecular subtype classification of T-ALL and identification of the stage of leukaemic arrest. Subgroup classifications based on oncogene expression often rely on comparisons made with incorrect biological reference material (Ballerini et al, 2002; Ferrando et al, 2002, 2004). This can result in incorrect interpretation and misdassification of T-ALL subgroups. Usage of the right reference material is essential for correct T-ALL subgroup classification, particularly when such T-ALL classification aims to identify prognostic subgroups with different clinical outcome. Although many have speculated and made assumptions regarding the usage of relevant reference material for T-ALL, no real attempt has been made to show that normal human thymocyte subsets are the most optimal biologically relevant reference material for comparison to T-ALL.
