The investigators have therefore chosen to replace Carmustine by Thiotepa and use the TEAM regimen as the new conditioning. Indeed, Thiotepa is approved by french national agency for the security of drugs (ANSM) for use as part of auto-HSCT conditioning regimen. The results of TEAM regimen in terms of efficacy and toxicity appear similar to those of BEAM. However, no study have been performed prospectively. Only small series and case reports have been reported.
