Comparison of the Effect of VRD and PCD in the Treatment of Multiple Myeloma Patients and the Influence on Cellular Immune Indexes and Long-Term Survival
Objective To investigate the clinical efficacy of bortezomib,lenalidomide combined with dexamethasone(VRD)and bortezomib,cyclophosphamide combined with dexamethasone(PCD)in the treatment of multiple myeloma(MM)patients.Methods A total of 78 MM patients admitted to Jinxiang County People's Hospital from January 2020 to December 2022 were selected as the research objects and divided into a control group and an observation group according to random number table method,with 39 cases in each group.The control group received PCD chemotherapy,and the observation group received VRD chemotherapy.The clinical efficacy,serum biochemical indicators,cellular immune indicators,long-term survival and occurrence of adverse reactions were compared between the two groups.Results The disease control rate of the observation group was 94.87%,which was higher than 79.49%of the control group,and the difference was statistically significant(P<0.05).After treatment,the M protein and bone marrow plasma cells in the observation group were(2.82±0.38)g/L and(4.32±0.45)%,respectively,which were lower than(4.05±0.42)g/L and(5.88±0.79)%in the control group,and the differences between the groups were statistical significance(P<0.05);CD3+,CD4+,CD4+/CD8+and Treg were(67.52±5.51)%,(43.24±4.12)%,(1.86±0.25)and(4.85±0.45)%in the observation group,respectively,which were higher than(62.34±5.42)%,(39.54±3.87)%,(1.72±0.23)and(4.31±0.42)%in the control group,and the differences between the groups were statistically significant(P<0.05).The long-term survival rate and incidence of venous thrombosis in observation group were 89.74%and 20.51%,respectively,which were higher than 71.79%and 5.13%in the control group,and the difference between the groups were statistical significance(P<0.05).Conclusion VRD is more effective in the treatment of MM,which can better regulate the cellular immune indexes of patients,reduce the levels of M protein and bone marrow plasma cells,and improve the long-term survival rate.However,the risk of venous thrombosis is high,and the application should be considered.
