Abstract

Introduction: The femur is a common site for Multiple Myeloma (MM) involvement. This study explores the impact of preventive surgery for anticipated femoral pathological fractures (IFF), based on Mirels classification, versus treatment of pathological femur fracture (PFF) on MM patient mortality and morbidity.

Methods: Retrospective cohort of 33 patients undergoing surgery due to femoral MM involvement (2004-2015), 18 patients with PFF, 15 patients with IFF, followed up until deceased or to July 2016. Demographic data, oncological, pathological, radiation, surgical reports, outpatient clinical records, and imaging studies were studied. Exclusion criteria included patients who had surgery at other medical centers.

Results: The mean age was 70.4 ± 13.6 and 62.6 ± 12.2 years (p = 0.1) in the PFF and the IFF cohorts, respectively, primarily women (55.6% and 46.7%, respectively). The average Mirels' score was 10.4 ± 1.2. Post-operative complications were observed in 25% of patients, with no difference between IFF & PFF. We did not find a difference in mortality between IFF and PFF cohorts (p = 0.59).

Conclusion: The femur is commonly involved in MM. This study found that actual fractures, compared to imminent fractures, do not affect MM morbidity or mortality. Our study shows that proximal femoral MM behaves differently from proximal femoral metastatic disease regarding the impact of surgery on life span. Due to the fracture healing potential of MM, an IFF can probably be treated initially conservatively unless it progresses to an actual fracture needing surgery. Future, more extensive studies are required before revolutionizing the proximal femoral Multiple Myeloma-related involvement treatment paradigm.
