Safety and efficacy of non-initial rapid infusion of rituximab plus chemotherapy in Chinese patients with CD20+ non-Hodgkin's lymphoma

Objective: To evaluate the safety and efficacy of rapid rituximab infusion (RRI) plus chemotherapy in patients with CD20(+) non-Hodgkin's lymphoma (NHL). Research design and methods: A total of 177 patients received 4 - 6 cycles of rituximab-based chemotherapy. The first cycle was given with standard schedule. In the second and subsequent cycles, RRI was initiated. Rituximab was administered as 20% of the dose infused in the first 30 min and the remaining 80% was given over 60 min. Benadryl and dexamethasone were given before infusions. Vital signs were measured at baseline and during infusion. Results: In the first cycle, 48 patients experienced grade I - II infusion reactions and two patients showed grade III - IV infusion reactions. Six patients experienced infusion reactions during RRI. Two patients showed grade III infusion reactions to RRI and dropped out of the study. With a median follow up of 37.5 months, the 3-year overall survival and progression-free survival rates of the whole cohort were 93.1 and 81.1%, respectively. Conclusions: Our preliminary observations suggested that RRI may be safe and feasible for patients with CD20(+) NHL.
