Bortezomib retreatment for relapsed and refractory multiple myeloma in real‐world clinical practice

Aims Studies have shown that bortezomib retreatment is effective in relapsed/refractory multiple myeloma (MM). The observational, prospective electronic VELCADE® OBservational Study (eVOBS) study assessed bortezomib‐based therapies for patients with MM in everyday practice. Here, we report on those patients receiving retreatment with bortezomib.
