The groups are apparently healthy control group (n = 20), non-small cell lung cancer stage 1 (n = 9), non-small cell lung cancer stage 2 (n = 12), and non-small cell lung cancer stage 3 (n = 12). *P < 0.05; **P < 0.01; ***P < 0.001; ****P < 0.0001. All biospecimens were obtained from the South Eastern Nebraska Cancer Center. Non-small cell lung cancers had been staged according to the American Joint Committee on Cancer TNM staging system[2]
