    Multiple myeloma (MM) is the second most common hematological malignancy


    Multiple myeloma (MM) is the second most common hematological malignancy


    EMD is divided into primary EMD (detected when MM is diagnosed) and secondary EMD (detected when MM relapses), and the prognosis of secondary EMD is poor


    They analyzed 234 patients with secondary EMD among 4,985 MM patients diagnosed in the Czech Republic from 2005 to 2017 to clarify the risk factors for the development of secondary EMD

    They found that younger age [<65 years; odds ratio (OR) 4.

    Figure 2: The impact of future development of secondary extramedullary multiple myeloma (EMD) on progression-free (PFS) and overall (OS) survival rates in different treatment lines


    Compared with NDMM patients without future EMD, newly diagnosed MM (NDMM) patients with subsequent EMD have a lower median progression-free (PFS) and overall (OS) survival rate [mPFS: 13.


    In general, they found that MM patients with future EMD development showed specific characteristics (younger age, extensive bone disease, IgA or nonsecretory MM) that were already present at the time of MM diagnosis
