Overall, 508 samples from 264 newly diagnosed PCN patients, were studied. CTPC were detected in PB of all active multiple myeloma (MM; 100%), and smoldering MM (SMM) patients (100%), and in more than half (59%) monoclonal gammopathy of undetermined significance (MGUS) cases (p  YR 2018 FD 2018-11-19 LK http://hdl.handle.net/10668/13210 UL http://hdl.handle.net/10668/13210 LA en DS RISalud RD Apr 8, 2025
