High risk cytogenetics were defined as del17p, t(4;14), t(14;16), 1q21 gain or amplification by fluorescence in situ hybridization....Len-combo regimens were either doublets (Len with dexamethasone [dex: n = 10], elotuzumab [n = 28] or ixazomib [n = 14]) or triplets (Len with bortezomib/dex [n = 10], ixazomib/dex [n = 10] or carfilzomib/dex [n = 6])...for patients with HR cytogenetic abnormalities other than 1q+ there was a trend towards better PFS with Len-combo (HR 0.59, CI 0.32-1.09, p = 0.09), without a difference in OS (HR: 0.79, CI: 0.37-1.65, p = 0.53)….In this single center retrospective analysis, intensification of post-transplant Len maintenance did not show an improvement in outcomes for HRMM patients. However, there was a trend towards improved PFS in patients with HR abnormalities other than 1q+.
