Pieternella J. Lugtenburg, MD, PhD, an internist and hematologist at Erasmus Medical Center in Rottenham, Netherlands, discusses the use of rituximab (Rituxan) as maintenance therapy in patients with diffuse large B-cell lymphoma (DLBCL).
Options are expanding for patients with DLBCL, however discovering therapies to extend survival for those patients who achieve complete remission (CR) remains a challenge with 40% of patients still having relapsed or refractory disease after rituximab is added to CHOP, says Lugtenburg.
In the second randomization of a phase II study, investigators evaluated rituximab as maintenance therapy versus observation for patients who achieved CR after R-CHOP. At median follow up of 79.9 months, the 5‐year DFS rate was 79% with rituximab maintenance versus 74% with observation (HR, 0.83; 95% CI, 0.57‐1.19; P = 0.31), showing no statistically significant benefit with rituximab. Investigators could not identify another subgroup of patients who benefitted from maintenance therapy in the study, Lugtenberg concludes.
