Clinical significance of peripheral blood-derived inflammation markers combined with serum eotaxin-2 in human colorectal cancer

To investigate the value of serum eotaxin-2, neutrophil/lymphocyte ratio (NLR), and platelet/lymphocyte ratio (PLR) in the diagnosis and prognosis of colorectal cancer (CRC). The association between different clinicopathological characteristics and eotaxin-2, NLR, and PLR in different patient groups was evaluated. The combined detection indicator and the combined detection's predictive effect on distant metastasis were examined. The receiver operating characteristic (ROC) curve was drawn to evaluate the efficacy of combined detection. The association between eotaxin-2, inflammation markers, and postoperative complications was assessed. Multivariate analysis to investigate the factors affecting the prognosis of patients with CRC. We detected a marked positive correlation between NLR and PLR (p < 0.05, r= 0.209). The AUC of serum eotaxin-2 combined with inflammation markers was 0.889, which was higher than single diagnosis. Compared with the single eotaxin-2 test, the combined detection of eotaxin-2 and inflammation markers might improve the specificity of CRC assessment. In univariate analysis, age, surgical method, high eotaxin-2, and high NLR were associated with postoperative complications. In multivariate analysis, age (≥ 60 years), high eotaxin-2, and high NLR were independent risk elements influencing postoperative complications of CRC. The distant metastasis, TNM staging -Ⅳ stage, NLR ≥ 3.18, and PLR ≥ 193 were independent factors affecting the prognosis of patients with CRC. The combined detection of eotaxin-2 and inflammatory markers has a particular value in improving the diagnosis of CRC, predicting distant metastasis, and guiding the frequency of reexamination after radical resection of CRC.
