Immunochemotherapy, in Vivo Purging, PBSC Mobilization and Autotransplant in Relapsed or Refractory Follicular Lymphoma

2-4 courses every 3 weeks with rituximab 375 mg/m\^2 on day 1, vincristine 1.4 mg/m\^2 on day 2 and cyclophosphamide 400 mg/m\^2 on days 2-6. Courses were started if granulocytes \>1.5 · 10\^9/l. The phase of peripheral blood stem cells (PBSC) mobilization coupled rituximab 375 mg/m\^2 on days 1 and 9 with high-dose cytarabine (AraC) 2 g/m\^2 every 12 hours on days 2 and 3. Granulocyte colony-stimulating factor (G-CSF)(5 mcg/kg/day subcutaneously) was administered from day 6. High-dose chemotherapy with autotransplant consisted of BEAM \[carmustine (BCNU), etoposide, Cytarabine (AraC), melphalan\] followed by the infusion of in vivo purged peripheral blood stem cells (PBSC) + 2 consolidation doses of rituximab 375 mg/m\^2 on days +14 and +21 after autotransplant.
