Overview
The ALK negative anaplastic large cell lymphoma is a peripheral T-cell lymphoma Non-Hodgkin's lymphoma. ALK negative ALCL T-cells express CD30, but not the ALK (Anaplastic Lymphoma Kinase) chimeric protein,[1] reason why the clinical outcome is more variable than the ALK(+)-ALCL.[2] Instead, this T-cells have a chromosomal rearrangement, affecting DUSP22 and TP63 gene. ALK(-) patients with DUSP22 mutation have shown to have a higher five-year overall survival rate in comparison to ALK(+)-ALCL.[3]
