Fig. 1: Binary heatmap showing cytogenetic abnormalities in 100 patients with pPCL.

Each row represents an individual patient; columns indicate the presence (red) or absence (light blue) of specific cytogenetic abnormalities detected by FISH at diagnosis. Left annotations denote FISH risk category and the number of HRCAs per patient. Abbreviations: pPCL primary plasma cell leukemia, FISH fluorescence in situ hybridization, HRCA high-risk cytogenetic abnormality.
