Light chain deposition disease (LCDD) is a systemic disorder characterized by deposition of non-amyloid monoclonal light chains. Renal dysfunction is a ubiquitous manifestation of the LCDD disease. Reports suggest that high-dose chemotherapy and autologous stem cell transplantation (ASCT) may be beneficial in the treatment of LCDD. However, the impact of ASCT on renal function is unclear. This study retrospectively reviewed the effect of ASCT on renal function in patients with LCDD.
