Orthopedic Surgical Treatment and Perioperative Complications in Multiple Myeloma Bone Disease: Analysis of a Series (2009–2018)
ANNALS OF SURGICAL ONCOLOGY(2020)
Abstract
Background More than 90% of patients with multiple myeloma (MM) develop lytic bone lesions that can be surgically treated for symptomatic relief and functional improvement. Methods This was a retrospective observational analytic study conducted between 2009 and 2018, including 58 patients with MM bone disease who underwent 77 orthopedic surgical procedures and were co-managed by internal medicine. Analysis of data related to MM bone disease, different modalities of surgical treatment, perioperative complications, and survival was performed. Results Median age was 72 years (66.5–77 years) and 56.9% of patients were males; 54.43% of injuries were located in the spine, 27.85% in the pelvis or lower limbs, 15.19% in the upper limbs, and 75.32% of patients had pathologic fractures. In 29.31% of the cases, the bone lesion was the debut of MM. Surgical procedures performed were mainly kyphoplasty (48.05%) and intramedullary nailing (29.87%). The overall complication rate following surgery was 74.03%. Only 20.78% of cases had a surgical complication. Among medical complications, we registered 28.57% transfusion requirements, 25.97% acute renal failures, 24.68% developed an infection, and 10.39% developed hypercalcemia. Patients were followed-up for a mean of 6.13 years and 37.93% suffered a new fracture. The median overall survival time for patients after surgery was 32.9 months (11.6–49). The estimated overall survival at 1, 3, and 5 years after surgery was 81.17%, 57%, and 34.11%, respectively. Conclusions The orthopedic surgical treatment of MM bone disease aims to improve symptomatology and patient quality of life; however, these patients have a high risk of perioperative complications and considerable early mortality, making multidisciplinary management with medical specialties essential.
