Whole-genome sequencing reveals cellular origin of concomitant chronic lymphocytic leukemia and multiple myeloma: a case report

Chronic lymphocytic leukemia (CLL) and multiple myeloma (MM) are hematological disorders affecting B cells. The clonal relationship between CLL and MM has not always been clarified, although this information is critical to understanding its pathogenesis. Here, we present a rare clinical case of sync...

description Chronic lymphocytic leukemia (CLL) and multiple myeloma (MM) are hematological disorders affecting B cells. The clonal relationship between CLL and MM has not always been clarified, although this information is critical to understanding its pathogenesis. Here, we present a rare clinical case of synchronous CLL and MM. Whole-genome sequencing (WGS) was performed using malignant lymph node (LN) and bone marrow (BM) tissues. Based on the high consistency of single nucleotide variants (SNVs), significantly mutated genes (SMGs), copy number variations (CNVs), different B cell receptor (BCR) IGH rearrangement features in LN and BM, and the different light-chain expression patterns in CLL and MM cells, we concluded that CLL and MM cells from this patient originated from the same hematopoietic stem cell/progenitors, different pro-B cells and suffered oncogenic mutations at different B cell differentiation stages. Depth analysis of genome features using WGS provides a new method to explore the process of malignant B cell genesis.
