Association of Serum CAR LMR and T Lymphocyte Subsets with Prognosis of Multiple Myeloma Patients
Objective:To investigate the association of serum C-reactive protein to albumin ratio(CAR),lymphocyte to monocyte ratio(LMR),and T lymphocyte subsets with the prognosis of multiple mye-loma(MM)patients.Methods:A total of 105 patients with multiple myeloma diagnosed and treated from January 2020 to January 2022 were selected as the study objects and set as the observation group.A total of 75 healthy controls were enrolled as the control group.MM patients were divided into poor prognosis group(n=34)and good prognosis group(n=71)according to whether recurrence or death occurred within 2 years of follow-up after treatment.Serum CAR,LMR,and T lymphocyte subsets(CD3+,CD4+,CD8+,CD4+/CD8+)were compared.Logistic regression analysis was used to analyze the effects of CAR,LMR,CD3+,CD4+,CD8+ and CD4+/CD8+ on the prognosis of MM patients.ROC curve analysis was used to analyze the AUC values,sensitivity,and specificity of CAR,LMR,CD3+,CD4+,CD8+,CD4+/CD8+ and T lymphocyte subsets to predict the prognosis of MM patients.Results:The CAR and CD8+ levels were significantly higher,while the LMR,CD3+,CD4+,and CD4+/CD8+ levels were significantly lower in the observation group than in the control group(P<0.05).The CAR and CD8+ levels were significantly higher,while the LMR,CD3+,CD4+,and CD4+/CD8+ levels were significantly lower in the poor prognosis group than in the good prognosis group(P<0.05).Binary Logistic regression model analysis showed that the increase of CAR and CD8+ and the decrease of LMR,CD3+,CD4+,CD4+/CD8+ would affect the prognosis of MM patients(P<0.05).ROC curve analysis showed that the combined parameters of CAR,LMR,CD3+,CD4+,CD8+,CD4+/CD8+ and T lymphocyte subsets predicted the prognosis of MM patients with AUC values of 0.637,0.792,0.726,0.767,0.669,0.750,0.853,respectively(P<0.05).Conclusion:Serum CAR,LMR,and T lymphocyte subsets showed abnormal expression trends in MM patients.The detection of their changes is helpful for providing im-portant reference for the assessment of the prognosis of MM patients.
