Abstract
Therapy for patients with multiple myeloma (MM) is currently unsatisfactory and most patients eventually succumb to relapsed disease. DCs are a subset of leukocytes with the capacity to initiate and control the adaptive immune response against many cancers, including MM. In MM patients, in vivo DC function is often abnormal, however, it appears that it can be restored by in vitro manipulation. This has led to the development of DC immunotherapy for MM patients. We review the background research leading to the recognition of an anti-MM immune response, and discuss abnormalities in DC function, potential tumor-associated Ags, and the results of clinical trials of DC immunotherapy in MM patients.
