Renal impairment (RI) is a severe complication throughout the course of multiple myeloma (MM). Bortezomib has been shown to be highly active in MM patients with RI. We designed this retrospective analysis to investigate the safety and efficacy of bortezomib-based therapy in 117 MM patients with RI, 14 cases required dialysis. A total of 603 cycles of bortezomib were administered (median number, five cycles/patient). Ten patients required early discontinuation of bortezomib because of WHO grade IV toxicity. The rate of bortezomib discontinuation in cases with severe, moderate and mild RI was 11%, 5% and 0%, respectively (P = NS). Overall, 91 episodes of WHO grade III/IV toxicity were observed. At least a partial response was documented in 83/113 evaluable patients (73%), including complete response (19%) and near complete response (8%). The overall response rate was similar across RI subgroups. Reversal of RI was documented in 41% of patients after a median of 2.3 months (range 0.4-7.9). In three of 14 patients on dialysis, renal replacement therapy was discontinued after 1, 1 and 4 months. The 2-yr estimate of response duration and overall survival was 70% and 51%, respectively. In conclusion, bortezomib-based regimens are safe and effective and should be considered as appropriate treatment options for MM patients with any degree of RI.
