How I Manage Systemic Light Chain Amyloidosis

Abstract

Light chain amyloidosis (AL) is a protein deposition disorder with a heterogenous pattern of organ involvement and dysfunction that varies by affected patient. Often diagnosed late after the onset of symptoms, appropriate and correct diagnosis, and prompt initial management, typically with anti-plasma cell therapy targeting the underlying cell producing the aberrant light chain protein, can lead to significant improvement in patient symptoms, organ function and lifespan. With recent publication of phase III studies focused on AL, and a changing regulatory landscape providing greater availability of novel therapies, the management of AL is in some ways more complex with greater options to consider. In this clinical review, a discussion of the diagnosis, staging, and goals of therapy transitions to a focus on contemporary management questions to outline our clinical approach to multi-disciplinary management and long term follow up for patients with suspected or confirmed AL.
