Current 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.

Objective Response Rate
The objective response rate (ORR) refers to the proportion of patients whose tumor volume reduction reaches a predetermined threshold and is maintained for the minimum required duration. It is calculated as the sum of complete response (CR) and partial response (PR) rates, i.e., ORR = CR + PR.
Local Response Rate
The local lesion response rate typically refers to the proportion of local lesions that show a reduction in volume or improvement in symptoms following treatment.
