Abstract

There is limited information on the outcome when organs other than heart or kidneys are involved by immunoglobulin light-chain amyloidosis (AL). We report the outcome of 53 patients with AL with gastrointestinal (GI), peripheral nerve (PN), liver, lung, or soft-tissue involvement, who underwent high-dose chemotherapy and autologous hematopoietic stem cell transplantation (auto-HCT) at our institution between 1997 and 2013. The median age at auto-HCT was 56 years (range, 35 to 74). One, 2, 3, or 4 organs were involved in 43%, 22%, 28%, and 4% of patients, respectively. Concurrent cardiac, renal, or both were involved in 24 (45%) patients. Forty-six patients received induction therapy before auto-HCT. The 100-day and 1-year treatment-related mortality (TRM) were 3.8% (n= 2) and 7.5% (n= 4), respectively. Forty-one (80%) patients achieved a hematologic response. Organ response at 1 year after auto-HCT was seen in 23 (57%) of the 40 evaluable patients. With a median follow-up of 24 months, the median progression-free survival and overall survival (OS) were 36 and 73 months, respectively. Auto-HCT was associated with a low TRM, durable organ responses, and a median OS of > 6 years in selected patients with AL and GI, PN, liver, lung, or softtissue involvement.
