Summary

To evaluate the efficacy and safety of the Pro-Pola （Pomalidomide, rituximab, orelabrutinib and polatuzumab vedotin) regimen in elderly patients (aged ≥70 years) with newly diagnosed diffuse large B-cell lymphoma (DLBCL).

3. Histologically confirmed treatment-naive DLBCL.
4. Life expectancy is\>3 months.
5. appropriate organ function: Cardiac function: Cardiac ejection fraction ≥50%; Liver function: alanine aminotransferase and aspartate aminotransferase ≤3 times the upper limit of normal; Renal function: Serum creatinine clearance ≥30mL/min; Lung function: SPO2 \>90% without oxygen inhalation
6. Adequate bone marrow reserve is defined as:

   Hemoglobin ≥8g/dL, platelet count ≥75×10\^9/L, Absolute neutrophil value ≥1.0×10\^9/L, If accompanied by bone marrow invasion, platelet count ≥50×10\^9/L, absolute neutrophil count ≥0.75×10\^9/L.
7. Patients have the ability to understand and are willing to provide written informed consent.
8. Subjects with childbearing or childbearing potential must be willing to practice birth control from the date of registration in this study to the follow-up period of the study.

Exclusion Criteria:
