简要总结
Given the established role of high dose cytarabine (HiDAC) combined with rituximab, along with recent data showing the encouraging efficacy of bendamustine, the investigators seek to integrate the synergistic effects of these medicines in alternating cycles as induction therapy prior to autologous stem cell transplant (ASCT). Based on prior experience with bendamustine and rituximab (BR) based induction therapy, the investigators seek to evaluate the efficacy and safety of stem cell mobilization in this pilot study

入选标准

- •Eligible for autologous stem cell transplantation.
- •ECOG performance status ≤ 2
- •Normal bone marrow and organ function as defined below:
- •Absolute neutrophil count ≥ 1,000/mcl unless in the opinion of the treating physician, neutropenia is due to splenomegaly or bone marrow involvement
- •Platelets ≥ 100,000/mcl unless in the opinion of the treating physician, thrombocytopenia is due to splenomegaly or bone marrow involvement
- •Total bilirubin ≤ 2 x IULN and AST(SGOT)/ALT(SGPT) ≤ 3.0 x IULN except when, in the opinion of the treating physician, is due to direct involvement of lymphoma (e.g., hepatic infiltration or biliary obstruction due to lymphoma) or Gilbert's disease
- •Creatinine ≤ IULN OR creatinine clearance ≥ 40 mL/min/1.73 m2 for patients with creatinine levels above institutional normal
- •Women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry and for the duration of study participation.
