The PDXs included DLBCL (n = 7) including one transformed DLBCL (tDLBCL) from marginal zone lymphoma, and one double-hit lymphoma (with MYC and BCL2 gene rearrangements), BL (n = 1), MCL (n = 2), angioimmunoblastic T-cell lymphoma (AITL, n = 2), peripheral T-cell lymphoma, not otherwise specified (PTCL, NOS, n = 1), anaplastic large cell lymphoma (ALCL), anaplastic lymphoma kinase (ALK)-positive (n = 1), and ALCL, ALK-negative (n = 1). The gene discussed is MYC; the disease is anaplastic large cell lymphoma.
