RESUMEN
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.
RESUMEN
<p><b>OBJECTIVE</b>To explore the risk factors of unplanned reoperation after radical resection for colorectal cancer.</p><p><b>METHODS</b>A retrospective analysis of 60 patients (within 14 to 24 days after the initial surgery) receiving unplanned reoperation after colorectal cancer surgery in the First Affiliated Hospital of Xinjiang Medical University from January 2010 to January 2014 was carried out, comparing with 120 randomly paired patients without reoperation during the same period. Univariate and multivariate Logistic regression analysis was performed to investigate the clinicopathologic characteristics of patients in both groups.</p><p><b>RESULTS</b>Univariate logistic regression analysis showed that male, massive blood loss, diabetes, high BMI, hypertension and poorer tumor staging were selected as possible risk factors, and surgeon and laparoscopic surgery as conservative factors (all P<0.05). Multivariate logistic regression analysis revealed that massive blood loss (OR=12.935, 95% CI: 2.267 to 73.806, P=0.004), diabetes (OR=1.747, 95% CI: 1.098 to 2.777, P=0.018) and male (OR=1.805, 95% CI: 1.074 to 3.034, P=0.026) were the independent risk factors of unplanned reoperation after radical resection for colorectal cancer.</p><p><b>CONCLUSION</b>For heavy bleeding, diabetes and male gender in patients with colorectal cancer, surgeon should pay attention to prevent the risk of postoperative unplanned reoperation.</p>
