What was measured

Number of days needed to achieve hematologic engraftment after high-dose chemotherapy induced myelosuppression is defined as the first day of neutrophils rising again above 0.5 G/l, and of platelets rising again above 20 G/L in the absence of platelet transfusions in the previous 3 days.

Analysis population: Time to neutrophil engraftment was defined as the duration between day 0 and the first 3 days of neutrophils \>0.5 × 109/L after ASCT.

Groups in this outcome

Arm A (Mel)

Melphalan 100mg/m2/day iv days -2 and -1 Melphalan: High-dose chemotherapy regimen for conditioning treatment before autologous stem cell Transplantation. Patients will receive melphalan at a total dose of 200mg/m2, divided in two doses of 100mg/m2/day on days -2 and -1, with the ASCT at day 0.

Arm B (BenMel)

Melphalan 100mg/m2/day iv days -2 and -1 Bendamustine 200mg/m2/day iv days -4 and -3 Melphalan: High-dose chemotherapy regimen for conditioning treatment before autologous stem cell Transplantation. Patients will receive melphalan at a total dose of 200mg/m2, divided in two doses of 100mg/m2/day on days -2 and -1, with the ASCT at day 0. Bendamustine: High-dose chemotherapy regimen for conditioning treatment before autologous stem cell Transplantation. Patients will receive bendamustine at a total dose of 400mg/m2, divided in two doses of 200mg/m2/day on days -4 and -3. Melphalan is given at a total dose of 200mg/m2, divided in two doses of 100mg/m2/day, each on days -2 and -1, with the ASCT at day 0.
