Abstract:
Objective:To investigate the value of CD64 index and C-reactive protein (CRP)/albumin (Alb) ratio (CRP/Alb) in predicting infection after modified radical mastectomy for breast cancer.Methods:The clinical data of 203 breast cancer patients who underwent modified radical mastectomy from January 2018 to August 2021 in Anhui No.2 Provincial People's Hospital were retrospectively analyzed. All cases were divided into infection group (40 cases) and non-infection group (163 cases) according to whether they were infected at the 1st month after operation. On the 1st day after operation, the serum CD64 index was measured by using flow cytometry, the serum CRP and Alb levels were measured by using immunoturbidimetry, and the CRP/Alb was calculated. The values of CD64 index and CRP/Alb in the diagnosis of infection after modified radical mastectomy for breast cancer were evaluated by using receiver operating characteristic (ROC) curve. The factors influencing infection after modified radical mastectomy for breast cancer were explored by using multivariate logistic regression.Results:The levels of CD64 index, CRP, CRP/Alb in the infection group were higher than those in the non-infection group [5.7±1.1 vs. 1.5±0.3, t = 32.05, P < 0.001; (78±13) mg/L vs. (11±3) mg/L, t = 39.26, P <0.001; 3.09±0.42 vs. 0.36±0.02, t = 57.48, P < 0.001], and the level of Alb in the infection group was lower than that in the non-infection group [(25±3) g/L vs. (32±4) g/L, t = 8.37, P < 0.001]. There were statistically significant differences in the catheterization time, CD64 index and CRP/Alb between the infection group and non-infection group (all P < 0.05); multivariate logistic regression showed that catheterization time >9 d, CD64 index >42.65 and CRP/Alb >1.25 were risk influencing factors of infection after modified radical mastectomy for breast cancer (all P < 0.001). The ROC curve results showed that the area under the curve, sensitivity, and specificity of CD64 index in the diagnosis of infection after modified radical mastectomy for breast cancer were 0.804, 89.5% and 85.4%, the CRP were 0.712, 70.6% and 76.5%, the Alb were 0.766, 72.4% and 75.4%, and the CRP/Alb ratio were 0.856, 88.0% and 90.5%. Conclusions:The CD64 index and CRP/Alb have certain values in the prediction of infection after modified radical mastectomy for breast cancer.
