Objectives This study compared the use of bortezomib in different combination regimens in newly diagnosed multiple myeloma (NDMM) patients who were transplant ineligible. Patients and methods We analyzed data from the Registry of Monoclonal Gammopathies (RMG) of the Czech Myeloma Group (CMG) to provide real-world evidence of outcome for 794 newly diagnosed MM transplant ineligible patients. The most frequently used regimen was VCd (bortezomib-cyclophosphamide-dexamethasone) (47.5%) over VMP (bortezomib-melphalan-prednisone) (21.7%), BDd (bortezomib-doxorubicin-dexamethasone) (9.8%) and VTd (bortezomib-thalidomide-dexamethasone) (2.9%). Results The overall response rate (ORR) was 69.2% (478/691), including 12.6% (≥ CR); 34.7% very good partial responses (VGPR); 21.9% partial responses (PR). Among triplet regimens, VMP was the most effective regimen compared to VCd, BDd and VTd. Median PFS was 22.3 vs. 18.5 vs. 13.7 vs. 13.8 months, (p=0.275), respectively and median OS was 49 vs. 41.7 vs. 37.9 vs. 32.2 months (p=0.004), respectively. The most common grade 3-4 toxicities were anemia in 17.4% and infections in 18% of patients. Conclusion Our study confirmed that bortezomib-based treatment is effective and safe in NDMM transplant ineligible patients; especially VMP, which was identified as superior between bortezomib-based induction regimens not only in clinical trials, but also in real clinical practice.
