Abstract
ObjectiveTo analyze the expression and significance of serum S100 calbindin A8 (S100A8), S100A9 and matrix metalloproteinase-9(MMP-9) in patients with non-small-cell lung cancer.
MethodsThere were 16 patients with NSCLC who were treated in our Sichuan Meishan People′s Hospital from January 2017 to January 2020 included in the NSCLC group.20 patients with benign lung diseases during the same period were selected as benign groups, and 20 healthy subjects during the same period were selected as control groups.The serum levels of S100A8, S100A9 and MMP-9 were measured by enzyme linked immunosorbent assay.The diagnostic value of the three parameters for NSCLC was analyzed by receiver operating characteristic curve, and the relationship between them and the pathological features was analyzed.
ResultsThe levels of serum S100A8, S100A9 and MMP-9 in NSCLC group were expressed high than benign group and healthy group, the difference was statistically significant (all P<0.05); The results of receiver operating characteristic curve showed that the area under the curve (AUC) of serum S100A8、S100A9 prediction NSCLC was 0.953 and 0.977 respectively, which had high diagnostic value; serum MMP-9 predicted AUC of NSCLC was 0.846, and the diagnostic value was moderate; by Spearman rank correlation analysis, S100A8, S100A9, MMP-9 expression were negatively correlated with the degree of tissue differentiation (all P<0.05), which was positively correlated with TNM stage (all P<0.05); and MMP-9 expression was related to the presence or absence of lymphatic metastasis (r=0.811, P<0.05).
Conclusionsserum levels of S100A8, S100A9 and MMP-9 are highly expressed in NSCLC patients, which are closely related to the histological differentiation and TNM stage, and can be used as potential molecular markers for the diagnosis and prognosis of NSCLC.
