Abstract

Autologous stem cell transplantation (ASCT) has been used in treatment for immunoglobulin light chain (AL) amyloidosis for over 2 decades and is generally reserved for patients younger than 70 years. Herein we report on outcomes of ASCT in a cohort of patients with AL amyloidosis aged 70 years or older. Between August of 2002 and April of 2017, 34 patients aged 70 years or older, with biopsy-proven AL amyloidosis, received an ASCT at the Mayo Clinic Rochester. Seventy percent of patients (n = 24) were transplanted within 6 months of diagnosis, and 74% (n = 25) received reduced-intensity conditioning with melphalan <200 mg/m2. Sixty-five percent of patients (n = 22) required hospitalization with a median duration of hospital admission of 8 days. Common reasons for hospitalization included fever or infection (14%), cardiac arrhythmia (14%), nutritional support (24%), and volume overload (19%). Overall response rate was 75%, with a complete response seen in 25% of patients. Overall survival and progression-free survival for the cohort were 66 months and 40 months, respectively. One patient died within 100 days of transplant, representing a 3% 100-day mortality rate. ASCT is safe and efficacious in carefully screened patients aged 70 or above.
