Abstract: We assessed the feasibility of a rapid infusion of rituximab with or without steroid-containing chemotherapy. Inclusion criteria: Key words: rituximab; lymphoma; drug administration; previous infusion of rituximab without grade 3 or 4 toxicity, lymphoid monoclonal antibody cells <5 · 109/L and rituximab dose of 375 mg/m2. Seventy patients Correspondence: Antonio Salar, MD, PhD, Department were treated with a total of 319 rapid rituximab infusions [126 (40%) of Clinical Hematology, Hospital del Mar, Passeig with and 193 (60%) without steroids].
