Several dysregulated or aberrant ALK forms have since been discovered as the cause of hematopoietic and non-hematopoietic malignancies, such as diffuse large B-cell lymphoma (DLBCL) 4, inflammatory myofibroblastic tumor (IMT) 5, neuroblastoma 6, anaplastic thyroid cancer 7, rhabdomyosarcoma 8, non-small-cell lung cancer (NSCLC) 9, and other diseases 10–17. This evidence concerns the gene ALK and diffuse large B-cell lymphoma.
