Objective: In clinical trials, the combination of bortezomib, thalidomide, and dexamethasone (VTD) has shown excellent results as induction treatment in patients with multiple myeloma. However, “real-life” data in unselected Caucasian patients are lacking.
Methods: We retrospectively analyzed 41 patients treated with VTD between 2005 and 2014.
Results: Post induction, the overall response rate was 78%, with ≥very good partial response (≥VGPR) in 54% and near complete/complete responses (nCR/CR) in 17% of the patients respectively. For patients proceeding to autologous stem cell transplantation (ASCT), post-transplant rates were 96% ≥VGPR and 48% nCR/CR. Median progression free survival (PFS) was 24 months and the estimated 1-year and 2-year overall survival (OS) rates were 95% and 76%, respectively. Subgroup analyses revealed significantly longer OS and PFS in patients with a ≥VGPR as first response status compared to those with a
Conclusion: The VTD regimen was found to be a highly effective and well tolerated induction regimen for multiple myeloma patients outside clinical trials.
