Abstract
e19530 Background: Renal impairment (RI) in Multiple Myeloma (MM) adversely affects the prognosis. Removing circulating free light chains via hemodialysis (HD) or plasma exchange (PLEX) along with chemotherapy can improve renal outcomes in MM. Methods: Per PRISMA guidelines a systematic search yielded 7311 articles since 2009 on 4 databases. After screening, 16 studies were included. Results: Main modalities were high cut off (HCO) HD, high flux (HF) HD, conventional HD and PLEX. N = 541 patients underwent HD/PLEX. 375/541 (69.3%) patients received HCO HD. In 2 RCTs, there was no significant difference in renal recovery (55.8% vs 51.6%; 41% vs 33%). The overall survival (OS) between the 2 groups was lower in the HCO group vs conventional HD (55.8% vs 76.6%) at 2 years while there was no significant difference in second study. Conclusions: HCO has failed to show promising efficacy with 2 RCTs failing to show statistical OS difference. There is paucity of data and further trials are needed. [Table: see text]
