Mexican Concensus Of Multiple Myeloma

To identify this increasingly common pathology, known as Multiple Myeloma, it is necessary to refer to the specific factors that characterize it; to this end, the classic criteria known as CRAB (hypercalcemia, renal failure, anemia and lytic lesions) are available, in which renal failure is one of the most frequent complications. Recently, 3 indisputable biomarkers have been described for the diagnostic support for Multiple Myeloma, which are: more than 10% of clonal plasma cells in BM or, a biopsy that corroborates the presence of a plasmacytoma, light chain ratio >= 100 mg/dL and more than one focal lesion on magnetic resonance imaging (MRI). A differential diagnosis for plasma cell leukemia, solitary bone plasmacytoma, and extramedullary plasmacytoma should always be considered. Being this an incurable disease, a lot of research has been done regarding its therapeutic management, whose main objective is the disappearance of plasma cells and the patient clinical improvement. Melphalan was the first drug that showed a benefit in 1958 and afterwards, with the addition of a steroid as a second drug, it was possible to improve response rates. Subsequently, different molecules were studied, forming multiple combinations, and achieving better rates of Overall Survival and Progression-Free Survival. Years later, with the arrival of proteasome inhibitors such as bortezomib, and immunomodulators such as thalidomide and lenalidomide, an important turnaround in the disease has been seen, as deeper responses, more prolonged remissions, and improvement in the quality of life of patients have been achieved. This consensus has the purpose of integrating a group of Mexican specialists and promoting the updating of this pathology.
