Abstract

This current retrospective multicenter analysis represents, to our knowledge, the first Italian study evaluating the efficacy and toxicity profile of "lenalidomide plus dexamethasone" as salvage therapy in patients with recurrent-refractory MM in the real life contest. Our study included patients who are usually excluded from clinical trials because of unfavorable baseline characteristics. Median OS was significantly longer in patients receiving "lenalidomide plus dexamethasone" for more than 12 months compared with those who had received "lenalidomide plus dexamethasone" for a shorter interval (P<0.0001). Median OS was not affected by best response achieved (P 0.4) and age (P 0.3). Quality of response did not correlate with number of previous lines of therapy (P 0.77) and age. Higher ORRs were recorded in the patients group with relapsed MM compared to those with refractory disease, but this difference was not statistically significant (P 0.38).

Keywords: Continuous treatment; Heavily pre-treated patients; Lenalidomide plus dexamethasone; Refractory/recurrent myeloma; Very elderly patients.
