About
This phase II trial is studying how well giving bendamustine hydrochloride, etoposide, dexamethasone, and filgrastim together for peripheral stem cell mobilization works in treating patients with refractory or recurrent lymphoma or multiple myeloma. Giving chemotherapy, such as bendamustine hydrochloride, etoposide, and dexamethasone, before a peripheral stem cell transplant stops the growth of cancer cells by stopping them from dividing or killing them. Giving colony-stimulating factors, such as filgrastim, and certain chemotherapy drugs helps stem cells move from the bone marrow to the blood so they can be collected and stored
Full description
PRIMARY OBJECTIVES:
I. To estimate the frequency of bendamustine (bendamustine hydrochloride) combined with GCSF (filgrastim) and dexamethasone to successfully mobilize peripheral blood stem cells (PBSCs) (as determined by collecting a minimum of 2 x 10^6 cluster of differentiation (CD)34+/kg).
SECONDARY OBJECTIVES:
I. To evaluate the response rate to bendamustine by diagnosis using established disease-specific response criteria.
II. To examine the number of apheresis cycles required to collect a minimum of 2 x 10^6 CD34+ cells/kg and ideally >= 5 x 10^6 CD34+ cells/kg (when achievable).
III. To assess the impact of bendamustine on B and T-lymphocyte populations in the peripheral blood (CD20+ cells, natural killer [NK] cells, CD4+25+ foxP3- regulatory cells, and CD8 cells).
OUTLINE:
Patients receive bendamustine hydrochloride intravenously (IV) over 30-60 minutes on days 1 and 2, etoposide IV over 60-240 minutes on days 1-3, dexamethasone orally (PO) on days 1-4, and filgrastim subcutaneously (SC) beginning on day 5 and continuing until peripheral blood stem cell collection is complete. Patients undergo leukapheresis daily for a minimum of 3 days or until > 5 x 10^6 CD34+/kg has been collected.
After completion of study treatment, patients are followed for up to 5 years.

- Fludarabine or other nucleoside analog (except gemcitabine or cytarabine) therapy within 24 months of registration; patients with limited exposure to fludarabine/other nucleoside analog therapy within 24 months may be considered eligible with review and approval by the PI or Co-PI prior to study entry
- Symptomatic cardiopulmonary disease
- Prior autologous or allogeneic transplantation
- Prior radioimmunotherapy within 12 weeks of registration
- Prior failed (< 5 x 10^6 CD34/kg) PBSC collection due to inability to mobilize stem cells
