Salvage Treatment Strategies and Clinical Outcomes in Diffuse Large B-cell Lymphoma After Failure of Polatuzumab Vedotin-based Combination Therapy: A Multi-center, Retro- and Prospective, Observational, Real-World Study

Diffuse Large B-cell Lymphoma (DLBCL) is a common hematologic malignancy. Even after standard first-line treatment, approximately 40% of patients will experience relapse. Currently, polatuzumab vedotin (pola) has been incorporated into DLBCL treatment (both for newly diagnosed and relapsed cases). However, for patients whose disease progresses after pola-containing regimens, the subsequent treatment options, efficacy, and survival outcomes remain unclear. Understanding these real-world scenarios is of great significance, as it can guide clinicians in developing better and more tailored treatment strategies for patients in the future.

Therefore, we plan to conduct this real-world study titled "Salvage Treatment Strategies and Clinical Outcomes in Diffuse Large B-cell Lymphoma After Failure of Polatuzumab Vedotin-based Combination Therapy", aiming to obtain real-world data from the Chinese population.
