NCI Definition: A T-cell peripheral lymphoma morphologically indistinguishable from anaplastic large cell lymphoma, ALK-positive. It is characterized by the absence of the translocation involving the ALK gene and lacks expression of ALK fusion protein. [1]

Anaplastic large cell lymphoma, ALK-negatives most frequently harbor alterations in STAT3, JAK1, TP53, STAG2, and SOCS1 [2].

Most Commonly Altered Genes in Anaplastic Large Cell Lymphoma, ALK-Negative

STAT3 Mutation, JAK1 Mutation, TP53 X307_splice, STAT3 Y640F, and STAT3 S614R are the most common alterations in anaplastic large cell lymphoma, ALK-negative [2].
