Objectives:
To investigate the effectiveness of 2 chemotherapeutic regimens, bendamustine plus rituximab (BR) or reduced-dose cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab (RD-R-CHOP), in elderly patients with treatment-naïve diffuse large B-cell lymphoma.
Methods:
A retrospective study was conducted to investigate the efficacy and safety of 2 frontline regimens, BR and RD-R-CHOP, in patients aged ≥75 years unfit for R-CHOP.
Results:
From January 2011 to December 2015, 26 patients received BR and 34 RD-R-CHOP. No significant difference was found in clinical background comparisons. The overall response rate was 50% and 79.4% for BR and RD-R-CHOP, respectively (P = .027). Compared with patients in RD-R-CHOP, those in BR had a lower complete remission rate (42.3% vs 70.6%, P = .036), higher progressive disease rate (38.5% vs 8.8%, P = .01), and poorer median overall survival (11.2 months vs 39 months, P = .035). The prognostic difference was mainly observed in patients with limited stage. By contrast, BR had better toxic profiles. Some patients in BR certainly showed long-term survivals.
Conclusions:
This study demonstrated better efficacy of RD-R-CHOP, indicating its administration might be considered whenever possible, especially for limited stage. However, BR is a reasonable alternative for those ineligible for anthracycline-containing regimens. Further studies are needed to guide treatment decisions.
