Univariate analysis demonstrated that the OS was significantly associated with smoking status (P = 0.033), TNM status (P = 0.014), tumor size (P = 0.002), SUVmax (P = 0.002), and TLR4 expression (P = 0.001), while DFS was directly influenced by TNM stage (P = 0.020), tumor size (P = 0.003), SUVmax (P = 0.002), and TLR4 expression (P = 0.003). This evidence concerns the gene TLR4 and neoplasm.
