Spatial and temporal tumor genomic heterogeneity in extramedullary multiple myeloma and solitary plasmacytoma with minimal marrow involvement
Basic Information
Description
To test the hypothesis that plasmacytomas can represent spatial and temporal clonal escape events, featuring distinct myeloma-defining genomic events characteristic of active disease, through the following specific aims:
Aim 1. Compare genomic driver events in paired samples from patients with newly diagnosed solitary plasmacytoma (SP) with minimal marrow involvement versus newly diagnosed multiple myeloma (NDMM) to identify myeloma-defining events in the plasmacytoma.
Aim 2. Compare genomic events in paired samples at MM relapse versus NDMM to identify genomic events associated extramedullary localization and progression of the disease.
