Abstract:
Objective:To investigate the efficacy of RCDOP (Rituximab, cyclophosphamide, liposome doxorubicin, vincristine and prednisone) regimen in patients with de novo diffuse large B-cell lymphoma (DLBCL), especially in those patients with multiple extra-nodal involvement or Bulky diseases.
Methods:A total of 87 newly diagnosed DLBCL patients who received RCDOP regimen from October 2012 to October 2017 were enrolled into this study. Survival functions were estimated using the Kaplan-Meier method and compared by the log-rank test, and χ2 tests were used for categorical data.
Results:Among the 87 DLBCL patients treated with RCDOP regimen, 81 patients achieved complete remission (CR) or partial remission (PR), with ORR as 93.1%. Patients were further classified into groups, according to the risk factors, such as IPI scores, multiple extra-nodal involvement, bulky disease, age>60, tumor Ki-67>80%, elevated serum LDH level and advanced Ann Arbor stage. The progression-free survival (PFS, P=0.084) and overall survival (OS, P=0.515) had no statistical difference among the IPI low risk (0-1 score) group, intermediate risk (2-3 scores) group and high risk (4-5 scores) group. Similarly, no statistical difference were fou nd in PFS and OS of patients with extra-nodal involvements ≥2 (P=0.303 and P=0.624), with bulky disease (P=0.518 and P=0.466), with age>60 (P=0.600 and P=0.183), with elevated serum LDH level (P=0.054 and P=0.880), with advanced Ann Arbor stage (P=0.075 and P=0.286), and with tumor Ki-67 over 80% (P=0.190 and P=0.109), when compared with those of patients without these risk factors.
Conclusion:RCDOP can improve the therapeutic effect and prognosis of DLBCL patients with certain high risk factors, such as intermediate and high IPI risks, multiple extra-nodal involvements, bulky disease, age over 60, elevated LDH level, advanced Ann Arbor stage and tumor Ki-67 over 80%.
