ALK and anaplastic large cell lymphoma: Most recently, Laginestra et al. validated a five miRNAs set (miR-515-3p, miR-155, miR-598, miR-625, miR-199a-5p) that can differentiate PTCL-NOS from ALCL/ALK−, a eight miRNAs panel (miR-652, miR-627, miR-519e, miR-487b, miR-324-5p, miR-449a, miR-381, miR-574-3p) that can be used to distinguish PTCL-NOS from AITL, and also a four miRNAs signature (miR-124, miR-325, miR-181a, miR-618) that can be used to identify ALCL/ALK− from ALCL/ALK+ disease group (72).
