Abstract：【Objective】To investigate the expression of Nanog in cancer tissue before chemotherapy in advanced lung adenocarcinoma and its influence on the chemotherapeutic effect and prognosis.【Methods】 Pathological data of fifty-six advanced lung adenocarcinoma cases confirmed by histopathology between January 2010 and December 2013 in our hospital was collected. All patients completed at least four cycles of pemetrexed chemotherapy combined with cisplatin. The expression of Nanog was detected by immunohistochemistry in all cancer tissues.【Results】 High expression of Nanog protein in cancer tissue occurred in 29 cases (51.8%) out of 56 cases of advanced lung adenocarcinoma, low expression in 27 cases (48.2%); There was no correlation between the expression level and the gender of the patients (P=0.643), age (P=0.143) and clinical stage (P=0.096); the efficiency of chemotherapy (24.1%) in the Nanog high expression group was lower than that of the low expression group (70.4%), the difference was statistically significant (P<0.05). Univariate analysis showed that clinical stage and Nanog expression levels were associated with clinical prognosis in patients with lung adenocarcinoma (P mean <0.05); Multivariate analysis showed that Nanog expression was an independent prognostic factor in patients with lung adenocarcinoma (P<0.05).【Conclusion】 Nanog high expression may indicate a poor response to pemetrexed chemotherapy combined with cisplatin in patients with lung adenocarcinoma, and even a worse clinical outcome.
