  1. aPloidy status, immunoglobulin translocation and copy number event data were extracted from WGS data.
  2. bMYC translocation (Ig or non-Ig) or intrachromosomal deletion is proximal to MYC.
  3. cECOG performance—0 = fully active, 1 = restricted in physically strenuous activity, 2 = ambulatory and capable of all self-care, 3 = capable of only limited self-care and 4 = completely disabled.
  4. dHigh risk defined as those patients with one or more high-risk events—del17p13, t(14;16) (MAF), t(14;20) (MAFB), t(8;14) (MAFA) and t(4;14) (NSD2/WHSC1/MMSET).
