Immunotherapy with rituximab during peripheral blood stem cell transplantation for non-Hodgkin's lymphoma

Peripheral blood stem cell grafts from patients with lymphoma are often contaminated with neoplastic cells. Administration of a lymphoma-specific monoclonal antibody before collecting stem cells may be one way of reducing the contamination. Similarly, an antibody after transplantation at a time of minimal residual disease may increase the efficacy of the procedure. The objective of this study was to determine the safety of using rituximab as …
