Multiple myeloma(MM) is a common malignant hematological disease. Dysregulation of micro RNAs(mi RNAs) in MM cells and bone marrow microenviroment has important impacts on the initiation and progression of MM and drug resistance in MM cells. Recently, it was reported that MM patient serum and plasma contained sufficiently stable mi RNA signatures, and circulating mi RNAs could be identified and measured accurately from body fluid. Compared to conventional diagnostic parameters, the circulating mi RNA profile is appropriate for the diagnosis of MM and estimates patient progression and therapeutic outcome with higher specificity and sensitivity. In this review, we mainly focus on the potential of circulating mi RNAs as diagnostic, prognostic, and predictive biomarkers for MM and summarize the general strategies and methodologies for identification and measurement of circulating mi RNAs in various cancers. Furthermore, we discuss the correlation between circulating mi RNAs and the cytogenetic abnormalities and biochemical parameters assessed in multiple myeloma.
