Objective To investigate the value of C-reactive protein to serum albumin ratio(CAR)in evaluating the prog-nosis of elderly patients with acute myeloid leukemia.Methods A retrospective analysis was performed on 84 elderly patients with non-M3 acute myeloid leukemia diagnosed in the Affiliated Hospital of Xuzhou Medical University from February 2018 to December 2022.According to the ROC curve,the optimal cut-off point of CAR was determined,and the patients were divided into a low CAR group and high CAR group.The differences of clinical indexes between the groups were compared.The survival curve was drawn by the Kaplan-Meier method,and the prognostic factors were analyzed by the COX proportional hazard regression model.Results According to ROC,the AUC of CAR was 0.870(95%CI:0.788-0.953,P<0.05),The optimal cutoff value for CAR was 0.370 as calculat-ed based on the Youden index,with a sensitivity of 86.2%and a specificity of 81.8%.The patients which CAR≤0.370 were the low CAR group and 49 patients with CAR>0.370 were in the high CAR group.In the high CAR group,the C-reactive protein value was higher(P<0.05),and the serum albumin value was lower(P<0.05).The patients in the low CAR group were more likely to a-chieve the first complete remission after induction chemotherapy(P<0.05).The overall survival and progression-free survival of the low CAR group were better than those of the high CAR group,and the differences were statistically significant(P<0.05).COX pro-portional hazard regression model showed that CAR was an independent risk factor affecting the prognosis of elderly patients with acute myeloid leukemia(P<0.05).Conclusion The higher CAR value suggests that the prognosis of elderly patients with non-M3 acute myeloid leukemia is worse,and CAR may be an effective marker for the prognosis rating of such patients.
