Treatment Options for Amyloidosis Associated With Plasma Cell Neoplasms

Treatment options for amyloidosis associated with plasma cell neoplasms include the following:

  1. Chemotherapy, IMiDs (immunomodulatory agents), and proteasome inhibitors.
  2. Stem cell rescue.
Chemotherapy

As is true for all plasma cell dyscrasias, responses have been reported for all the same regimens active in multiple myeloma.[1-9]

Two randomized trials showed prolonged overall survival (OS) with the use of oral chemotherapy with melphalan with or without colchicine versus colchicine alone.[10,11][Level of evidence: 1iiA]

Stem cell rescue

A randomized, prospective study of 100 patients with immunoglobulin light-chain amyloidosis compared melphalan plus high-dose dexamethasone with high-dose melphalan plus autologous stem cell rescue.[12] After a median follow-up of 3 years, median OS favored the nontransplant arm (56.9 months vs. 22.2 months; P = .04).[12][Level of evidence: 1iiA] The 24% transplant-related mortality in this series and others reflects the difficulties involved with high-dose chemotherapy in older patients with organ dysfunction.[12-17] A randomized trial confirming the benefit of autologous transplantation is not anticipated.[18]

An anecdotal series describes full-intensity and reduced-intensity allogeneic stem cell transplantation.[19]

Current Clinical Trials

Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with primary systemic amyloidosis. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

General information about clinical trials is also available from the NCI Web site.
