Clinical Features of Bone Complications and Prognostic Value of Bone Lesions Detected by X-ray Skeletal Survey in Previously Untreated Patients with Multiple Myeloma.

Multiple myeloma is usually associated with the presence of lytic bone lesions. We reviewed the clinical and laboratory features of patients with newly diagnosed myeloma bone disease and evaluated the prognostic significance of different X-ray image patterns in symptomatic MM patients. We retrospectively reviewed 260 patients with newly diagnosed MM. X-ray image patterns of patients were correlated with hematologic parameters, therapeutic reaction and patient survival. Patients with the X-ray imaging pattern of grade 2-4 had significantly higher marrow plasma cells levels, marrow CD138(+) D38(+) cell percentage, ECOG performance score, and serum IL-6 level than grade 0-1. Univariate analysis demonstrated that skeletal lytic changes associated with rapid progression. There is a high incidence of myeloma bone disease (MBD) in patients of MM in China. Patients of extensive bone lesions have more severe alterations in hematologic parameters than do those without bone lesions and severe bone lesions is an important adverse prognostic factor associated with a short TTP.
