Background/Objectives: Bendamustine (BEN) combined with rituximab (RTX) remains a standard first-line therapy for transplant-ineligible patients with newly diagnosed mantle cell lymphoma (MCL)... Our findings support the efficacy of oral BEN as both a monotherapy and as part of an all-oral treatment regimen for MCL. These results warrant further investigation into the clinical potential of oral BEN, particularly in combination with targeted agents.
