N2 - Patients with immunoglobulin light chain (AL) amyloidosis undergoing peripheral blood hematopoietic stem cell (PBSC) mobilization for autologous hematopoietic stem cell transplantation (auto-HCT) can experience significant morbidity and mortality. The purpose of this study was to characterize the adverse events and identify prognostic factors associated with the development of morbidity and mortality in patients with AL amyloidosis who had begun PBSC mobilization for auto-HCT. A retrospective study was performed in 101 consecutive patients with AL amyloidosis who underwent PBSC mobilization for auto-HCT between January 2006 and December 2013. A composite primary endpoint of morbidity and mortality during PBSC mobilization was used. Forty-one patients (41%) experienced at least 1 adverse event, including 4 deaths during PBSC mobilization. Adverse events included in this composite endpoint were cardiac events, thromboembolic events, bleeding events, unplanned hospitalization, weight gain >2% necessitating diuretic intervention, and death. Low serum albumin levels, elevated N-terminal pro-brain natriuretic peptide, and increased interventricular septal thickness were significantly associated with the composite primary endpoint (P =.024,.001, and.006, respectively). The median progression-free survival from the start of PBSC mobilization was 4.7 years, and the median overall survival was 6.5 years. In general, PBSC mobilization is associated with minimal complications, but patients with AL amyloidosis can experience more frequent and severe complications, such as volume overload and weight gain. Careful patient selection is warranted in patients with AL amyloidosis before proceeding to PBSC mobilization and auto-HCT.
