High expression of IL-6 mRNA in tumor tissue predicts poor prognosis of lung cancer patients. (a) High expression of IL-6 in the tumor predicts a worse overall survival of lung cancer patients. (b,c) High expression of IL-6 receptor and IL6ST/gp130, respectively, in the tumor predict prolonged survival of lung cancer patients. HR = hazard ratio.
