ABSTRACT
OBJECTIVES:
Osteolytic bone lesions are common complications in multiple myeloma (MM), and can have an impact on quality of life due to the risk of fractures. Trabecular bone score (TBS) is a novel texture index derived from dual energy x-ray absorptiometry (DXA) of lumbar spine (LS) images that provides information about bone microarchitecture. The aim of this study was to evaluate whether TBS is useful in predicting bone fractures in MM patients.METHODS:
TBS was calculated retrospectively from existing DXA images of the LS, in 20 patients with newly diagnosed MM. We analyzed the development of fractures in these patients.RESULTS:
The median age of the patients was 66 years (range, 49–77 years). Osteolytic bone lesions were observed in 18 patients (90%) at the time of diagnosis. The median duration of follow-up was 40.0 months (95% confidence interval [CI], 33.2–46.2), 6 fracture events (long-bone fractures in 5 events, vertebral fracture in 1) occurred in 5 patients (25%). There were no significant differences between patients who experienced new onset fractures and patients who did not for all TBSs and T-scores, although the fracture group had lower levels than the no fracture group. However, among TBSs of individual LSs, only L2 showed significantly lower scores in patients who developed fractures (1.135 ± 0.085 [95% CI, 1.030–1.241] vs. 1.243 ± 0.169 [95% CI, 1.149–1.336], P = 0.032).CONCLUSIONS:
TBS of the LS in MM patients may be helpful in predicting development of fractures; however, further investigation is needed.
