Univariate Cox regression analysis showed that age (P = 0.022), T stage (P < 0.001), N stage (P < 0.001), M stage (P < 0.001), pathologic stage (P < 0.001), curative outcome (P < 0.001) and TXN expression (P = 0.024) were prognostic of survival in lung cancer patients, whereas gender was not. Here, TXN is linked to lung cancer.
