RecruitingDrug-Eluting Bead-Based Transarterial Chemoembolization (DEB-TACE) as a Local Salvage Therapy for Large Lesions in Relapsed and Refractory Diffuse Large B-Cell LymphomaCurrent exploration of local therapies for large Diffuse Large B-Cell Lymphoma (DLBCL) masses remains in its infancy. This study aims to retrospectively evaluate the safety, efficacy, and tolerability of Drug-Eluting Bead-Based Transarterial Chemoembolization (DEB-TACE) for treating recurrent and refractory DLBCL masses. It seeks to establish a novel local salvage treatment strategy for such patients while providing preliminary theoretical foundations and clinical data to support future large-scale, multicenter clinical trials.
