High-dose conditioning regimens commonly used in patients with non-Hodgkin lymphoma are BEAM (BCNU, etoposide, cytarabine, and melphalan), BEAC (BCNU, etoposide, cytarabine, and cyclophosphamide), CBV (cyclophosphamide, carmustine, and etoposide), and combination regimen with total body irradiation. Three-year progression free survival of patients with non-Hodgkin lymphoma received above high-dose chemotherapy followed by autologous stem cell rescue was reported as 40-50%, which is still unsatisfactory.
