Abstract
The standard of care for chronic lymphocytic leukaemia is fast changing. For younger patients, frontline chemoimmunotherapy with regimens such as fludarabine, cyclophosphamide, and rituximab 1 Thompson PA Tam CS O'Brien SM et al.

Thus, current efforts are directed towards the use of less toxic drugs such as monoclonal antibodies and lenalidomide as post-induction therapy, commonly referred to as maintenance therapy. Rituximab maintenance versus observation alone in patients with chronic lymphocytic leukaemia who respond to first-line or second-line rituximab-containing chemoimmunotherapy: final results of the AGMT CLL-8a Mabtenance randomised trialRituximab maintenance therapy prolongs progression-free survival in patients achieving at least a PR to induction with rituximab plus chemotherapy, and the treatment is well tolerated overall. Although it is associated with an increase in infections, there is no excess in infection mortality, suggesting that remission maintenance with rituximab is an effective and safe option in the management of chronic lymphocytic leukaemia in early treatment phases.
