Community-based trial of R-CHOP and maintenance rituximab for intermediate- or high-grade non-Hodgkin lymphoma with first-cycle filgrastim for older patients.

Background: Administration of full-dose R-CHOP (rituximab/cyclophosphamide/doxorubicin/vincristine/prednisone) chemotherapy is important to maximize response in patients with intermediate-or high-grade non-Hodgkin lymphoma but might be difficult in older patients.

Patients And Methods: This community-based study was conducted to determine response, toxicity, and disease-free survival in patients with intermediate-or high-grade non-Hodgkin lymphoma receiving R-CHOP with filgrastim. Patients received 6-8 cycles of R-CHOP followed by 4 cycles of maintenance rituximab for responders.

Fourteen-day CHOP supported with granulocyte colony-stimulating factor in patients with aggressive non-Hodgkin's lymphoma: results of a phase II study.

The safety and efficacy of compressed-cycle (14-day) standard-dose CHOP (cyclophosphamide/doxorubicin/vincristine/prednisone) supported with prophylactic recombinant granulocyte colony-stimulating factor (G-CSF; filgrastim) were evaluated in patients with aggressive non-Hodgkin's lymphoma (NHL). Patients with intermediate- or high-grade NHL (Working Formulation groups D-H and J; N = 120), accrued from 25 clinical practices, were given 6 cycles of standard-dose CHOP every 14 days. Granulocyte colony-stimulating factor 5 microg/kg was given daily subcutaneously in each cycle, starting on day 2 and continuing until the absolute neutrophil count was = 10000/microL.
