[Analysis of long-term survivors with cardiac AL amyloidosis].

Cardiac AL amyloidosis (CA) is generally known as a severe disease with very poor prognosis. Here we retrospectively examined seven patients with CA in our cohort who achieved long-term survival. All six patients who underwent high-dose melphalan and autologous stem cell transplantation (ASCT) survived for >3 years, whereas four patients survived for >5 years. Patients who underwent ASCT had prompt hematological responses, and five patients showed organ responses. ASCT helps to achieve a quick and deep hematological response required for long-term survival in patients with CA. New agents have been implemented for the treatment of CA. However, the risks and benefits of each treatment modality should be considered according to patient condition, thus making the best use of ASCT in combination with new agents for the treatment of CA.
