Abstract The HOVON 104 studied bortezomib‐dexamethasone induction therapy and autologous stem cell transplantation in 50 patients, of whom 35 received an autologous stem cell transplantation (ASCT). We demonstrate a 5‐year overall survival (OS) of 73% and progression‐free survival (PFS) of 52% for all 50 patients with a median follow‐up of 61.3 months. For the 35 transplanted patients, calculated from the date of ASCT, the 5‐year OS and PFS were 91% and 68%, respectively. After ASCT, the rate of organ response improved over time but stabilized around 3 years. A complete cardiac response was seen in around 60% of patients and remained stable from 2 years onward. Reaching complete renal response was slower over time and achieved by 61% of the renal‐affected patients at 5 years. We confirm the excellent outcomes after ASCT and demonstrate a 60% complete organ response with longer follow‐up.
