Analysis of treatment efficacy in the GEM-CESAR trial for high-risk smoldering multiple myeloma patients: Comparison between the standard and IMWG MRD criteria and QIP-MS including FLC (QIP-FLC-MS)
8512 Background: The GEM-CESAR trial is a potentially curative strategy for high-risk smoldering multiple myeloma (HRsMM) patients (pts) in which the primary endpoint is the achievement of sustained minimal residual disease (MRD) negativity in the bone marrow (BM) by next generation flow (NGF). The value of BM MRD assessment in MM is proven, but alternative, non-invasive methods, accurately reflecting disease burden are needed. Methods: Pts received six 4-week cycles of KRd as induction (K:36mg/m2 twice weekly, R: lenalidomide 25mg po od days 1-21 and d:dexamethasone 40mg po weekly) followed by melphalan 200mg/m2, two further cycles of KRd as consolidation and up to 2 years of Rd (R:10mg/d…
Whole-epigenome analysis in multiple myeloma reveals DNA hypermethylation of B cell-specific enhancers
Abstract Analyzing the DNA methylome of multiple myeloma (MM), a plasma cell neoplasm, by whole-genome bisulfite sequencing and high-density arrays, we observed regional DNA hypermethylation embedded in extensive global hypomethylation. In contrast to the widely reported DNA hypermethylation of promoter-associated CpG islands (CGIs) in cancer, hypermethylated sites in MM as compared to normal plasma cells were located outside CpG islands and were unexpectedly associated with intronic enhancer regions active in normal B cells. Both RNA-seq and in vitro reporter assays indicated that enhancer hypermethylation is globally associated with downregulation of its host genes. ChIP-seq and DNAseI-se…
