Intravenous busulfan containing regimens as conditioning regimen have been used for both allogeneic and autologous stem cell transplantation in patients with hematologic and non-hematologic malignancies.
The investigators have previously studied that conditioning regimen of i.v. busulfan/melphalan/etoposide (BuME) was well tolerated and effective in patients with relapsed or high risk NHL. And busulfan/cyclophosphamide/etoposide (BuCE) conditioning regimen has been extensively utilized in ASCT for NHL.
Therefore, based on the encouraging results, the investigators will conduct a randomized phase II multicenter trial of BuCE versus BuME as conditioning therapy for ASCT in patients with NHL.
