High-dose therapy with melphalan+autologous stem cell transplant (HDT/ASCT) resulted in better progression-free survival than standard dose therapy (SDT) in patients with multiple myeloma, according to a meta-analysis of 9 studies involving nearly 6,000 individuals. Investigators included studies comparing single HDT/ASCT with SDT using novel agents. They looked at progression-free and overall survival, complete response, and treatment-related mortality. Among the findings:
- Patients receiving HDT/ASCT were 27% more likely to experience complete response than those receiving SDT.
- HDT patients experienced better progression-free and overall survival.
- Patients receiving tandem HDT/ASCT experienced the most favorable progression-free survival, followed by single HDT/ASCT with bortezomib, lenalidomide, and dexamethasone; and single HDT/ASCT alone.
- No HDT/ASCT-based approach significantly impacted overall survival.
- HDT/ASCT treatment-related mortality was minimal.
