Abstract
Maintaining high relative dose intensity (RDI) is associated with improved outcomes, especially in patients with aggressive B-cell non-Hodgkin lymphoma (NHL). To evaluate changes in practice, we examined RDI, chemotherapy treatment patterns, dose delays and reductions, neutropenia and related consequences, and supportive care in 500 patients with aggressive B-cell NHL treated between 2006–2009. We then compared the results to a previous study of patients treated between 1993–2001. Relative to the previous study, rituximab was a common addition to CHOP-21 (91% vs. 3%), more patients received an RDI ≥ 85% (68% vs. 52%), and fewer patients experienced dose reductions (21% vs. 35%), though incidences of dose delays were similar (26% vs. 23%). Incidences of febrile neutropenia (FN; 12% vs. 21%) and FN-related hospitalizations (10% vs. 16%) were lower. Finally, more patients received primary prophylaxis with colony-stimulating factors (75% vs. 12%). Together, these results illustrate evolving practice patterns for patients with aggressive B-cell NHL.
