Popis: Renal impairment (RI) is a frequent complication of multiple myeloma (MM) and is associated with significant morbidity and risk of early death. Patients with severe RI (eGFR 60 ml/min/1.73 m2, renal partial response (PRrenal) as an increase of eGFR from The median age of patients was 65 years (range: 37-88 years) and 21% of them were >75 years of age. The median eGFR was 11.2 ml/min/1.73 m2 (range: 3.4- 29.2 ml/min/1.73 m2); 64% had eGFR An improvement of renal function (at least MRrenal) was recorded in 39 patients (70%) within a median time of 21 days (range 4-152 days). CRrenal was documented in 43% of patients and PRrenal in 9% (major renal response rate of 52%). Seven of 16 (44%) patients who required dialysis became dialysis independent. The median time to major renal response was 28 days (range 7-152 days). Patients with eGFR ≥15 ml/min/1.73 m2 (p=0.06) and age 12,500 mg/L as a cut-off associated with major renal response: only 16% of patients with FLCs >12,500 mg/L achieved a major renal response vs 59% of the others (p=0.053). Three-drug combinations (VTD, VCD, PAD, VMP) vs VD alone were associated with higher probability of major renal responses (65% vs 26%; p=0.006). Myeloma response to treatment by IMWG criteria was predictive of major renal response (p=0.05) in the univariate analysis. In multivariate analysis, adjusted for age >65 years and need for dialysis, the use of three-drug combinations was independently associated with a higher probability of major renal response (OR: 3.91, 95% CI 1.014-15, p=0.048). There was also a trend towards a shorter time until a major renal response for patients treated with three vs two drugs (35 vs >90 days, p=0.14). There was no significant difference in the probability of major renal response or time to renal response for those who received VTD vs VCD, PAD or VMP, even after adjusting for need of dialysis and age. Among patients who required dialysis, 9 (56%) received a three drug combination (5 VTD, 3 VCD and one PAD); among patients who became independent of dialysis 3 received VTD, 1 PAD and 3 VD. An early death (within In conclusion, our data indicate that bortezomib–based regimens can improve renal function in the majority of patients with severe RI. Three drug combinations based on VD are associated with a higher probability of major renal response and with a shorter time to renal recovery and should be offered to all newly diagnosed patients with severe RI. The FLC level could be used as a predictive factor for renal response. Disclosures No relevant conflicts of interest to declare.
