Clinical Trial Summary

The purpose of this study is to evaluate if the use total marrow irradiation (TMI) as a sole preparation for the first autologous hematopoietic stem cell transplantation (autoHSCT) followed by high-dose melphalan used prior to second autoHSCT is safe and effective in patients with multiple myeloma (MM).


Clinical Trial Description

AutoHSCT is a standard treatment of patients with MM. According to soem clinical evidence double autoHSCT provides survival advantage compared to a single procedure. Most frequently used conditioning regimen consists pf high doses of melphalan (HD-MEL). In some studies it was used in combination with total body irradiation (TBI), which, however was associated with significant toxicity. In our center the standard procedure includes TBI as a single treatment at 1st autoHSCT and HD-Mel at 2nd autoHSCT.

As in MM malignant plasma cells are localized almost exclusively in bone marrow there is rationale to limit irradiation to bones. For this purpose in the current study we substitute TBI with TMI. Additional boosts are provided for active sites of disease based on PET/CT imaging. Our intention is to minimize toxicity while maintaining the treatment efficacy. ;
