What have we learn • Velcade especially benefit t(4; 14) patients • Inclusion of What have we learn • Velcade especially benefit t(4; 14) patients • Inclusion of Velcade (and hence prolonged use) in different phases of treatment is important in high-risk disease • The use of double autologous transplant seem to also be an important factor. • Revlimid seem to have a more moderate and less consistent effect on high-risk disease • Thalidomide maintenance contra-indicated in 17 p 13 deletion • Newer Imids and PI may be more effective

Conclusion • No current routine role for NGS in clinic yet • We should Conclusion • No current routine role for NGS in clinic yet • We should adopt standardized risk categories Ø Revised ISS should be current gold standard Ø GEP and post-treatment MRD/Imaging await further studies • No evidence for the routine application of risk-adapted therapy Ø Best evidence is use of Velcade for patients with t(4; 14) • Should incorporate risk stratification into design of clinical trials Ø Test hypothesis in high-risk patients e. g. Velcade maintenance, double transplant, allo-SCT, Use of novel PI and Imids upfront
