Relapsed/Refractory Follicular Lymphoma: Current Advances and Emerging Perspectives

Abstract

Follicular lymphoma (FL) is a prevalent indolent non-Hodgkin lymphoma (NHL) characterized by a relapsing course and eventual refractoriness to therapy. Despite advancements in treatment, FL remains incurable, necessitating ongoing research into novel therapeutic strategies. This review provides a comprehensive overview of current standard treatments for relapsed or refractory (R/R) FL, including chemoimmunotherapy and stem cell transplantation, and delves into emerging therapies such as chimeric antigen receptor (CAR) T-cell therapy and bispecific antibodies. We discuss the efficacy and safety profiles of these innovative treatments, their integration into existing treatment paradigms, and the potential they hold in altering the natural history of FL. Additionally, we explore the challenges associated with these therapies, including accessibility, cost, and long-term management of adverse effects. By examining the evolving therapeutic landscape, this review aims to provide insights into future directions for achieving sustained remission and improving the quality of life in patients with R/R FL.
