Reversibility of renal failure in newly diagnosed patients with multiple myeloma and the role of novel agents

Abstract

The purpose of this analysis was to assess the effect of novel agent-based regimens on the improvement of renal impairment (RI) in newly diagnosed patients with multiple myeloma. Ninety-six consecutive patients with RI received conventional chemotherapy (CC)-based regimens (n=32), IMiDs-based regimens (n=47) or bortezomib-based regimens (n=17) as frontline therapy. Improvement of RI was more frequent in patients treated with novel agents (79% in IMiD- and 94% in bortezomib-treated groups versus 59% in CC-treated group; p=0.02). Bortezomib-based regimens and CrCl>30 ml/min at baseline independently correlated with a higher probability of at least renal partial response (PRrenal) and with a shorter time to PRrenal or better. Thus bortezomib-based regimens may be the preferred treatment for newly diagnosed myeloma patients with RI.
