Abstract:
Objective:To investigate the prognostic value of urinary interleukin(IL)-8 in elderly patients with non-small cell lung cancer (NSCLC).Methods:The clinical data of 110 elderly patients with NSCLC treated in Beijing Hepingli Hospital from January 2018 to January 2019 were collected, and the relationship between urinary IL-8 and clinicopathological characteristics were analyzed. The best cut-off value was determined by receiver operating characteristic (ROC) curve. The factors affecting the survival and prognosis of elderly patients with NSCLC were determined by univariable and multivariable Cox proportional hazards regression models.Results:The best cut-off value of urine interleukin-8 for predicting prognostic of elderly patients with NSCLC was 26.08 ng/L, the specificity was 80.00%, the sensitivity was 84.60%. The level of urine IL-8 was related to neutrophil cell count, clinical stage and serum IL-8 level ( P<0.05). The results of Cox multivariate analysis showed that the age ( HR = 4.810, P = 0.000), serum soluble fragment of cytokeratin 19(CYFRA211) ( HR = 2.728, P = 0.017), clinical stage ( HR = 2.090, P = 0.014), urine IL-8 ( HR = 4.451, P = 0.000) were independent risk factors for survival of elderly patients with NSCLC. Conclusions:Urine IL-8 is an independent prognostic risk factor of survival of elderly patients with NSCLC, it can be used as one of the indicators to evaluate the survival prognosis of patients.
