Abstract

Abstract:

Objective To investigate the roles of serum interleukin-8（IL-8）and matrix metalloproteinase-2（MMP-2） levels in predicting the prognosis of non-small cell lung cancer（NSCLC） patients undergoing thoracoscopic segmentectomy. Methods Totally，101 patients with NSCLC who underwent thoracoscopic segmentectomy were enrolled. The general data were collected. IL-8 and MMP-2 were determined. The patients were followed up for 3 years. According to whether the patients had recurrence，they were classified into recurrence group and non-recurrence group. Binary Logistic regression analysis was used to analyze the risk factors affecting recurrence. Receiver operating characteristic（ROC） curve was used to analyze the clinical value of preoperative serum IL-8 and MMP-2 levels in predicting the prognosis of patients. Kaplan-Meier survival curve and Log-rank χ² analysis were used to analyze the recurrence rate of NSCLC patients. Results Compared with non-recurrence group，the preoperative serum IL-8 and MMP-2 levels were higher in recurrence group（P<0.05）. The levels of IL-8 and MMP-2 were taken as cut-off values，and all the patients were classified into high expression group and low expression group. The results of binary Logistic regression analysis showed that preoperative serum IL-8≥87.52 ng/L and MMP-2≥477.86 ng/mL are independent risk factors that affected recurrence[odds ratios（OR） were 24.50 and 23.56，95% confidence intervals（CI） were 18.94-37.23 and 18.01-38.29]. ROC curve results showed that the area under curve（AUC） of IL-8 predicting recurrence was 0.834，and the AUC of MMP-2 predicting recurrence was 0.858. The results of Kaplan-Meier survival curve analysis showed that compared with IL-8 low expression group or MMP-2 low expression group，IL-8 high expression group or MMP-2 high expression group had a higher cumulative recurrence rate（P<0.001）. Conclusions The preoperative serum IL-8 and MMP-2 levels can be used as biological markers to evaluate the prognosis of patients with NSCLC after thoracoscopic segmentectomy.
