The Necessary For Long-Term Follow-Up Of Mutated Genes And Clonal Evolutions In Multiple Myeloma Combined With Cfdna Assay

Introduction)Somatic mutations in multiple myeloma (MM) are strongly related to the clinical outcome and clonal evolution over the clinical course, and are a major problem. From a clinical viewpoint, although numerous novel drugs have been utilized, achieving long-lasting and complete remission remains difficult. Recent studies have elucidated the mutated genes using next-generation sequencing, and have examined how clonal change can be acquired in myeloma. In this study, we traced the transition of the somatic mutations of bone marrow tumor cells in patients with MM over a long-term follow-up. Furthermore, we compared the somatic mutations found in serum cell-free DNA (cfDNA) and mutated genes obtained from bone marrow myeloma cells.
