Cten is a recently isolated gene, which has homology with tensin suggesting that it is a focal adhesion molecule. Tensin family proteins play an important role in cell motility. We attempted to determine the influence of cten expression on clinicopathological features in patients with lung cancer who had undergone surgery. Expression of cten messenger RNA was evaluated by reverse transcription-polymerase chain reaction (RT-PCR) in 89 lung carcinomas and adjacent histological normal lung samples using LightCycler. Cten/glyceraldehyde-3-phosphate dehydrogenase (GAPDH) mRNA expression was not significantly different between lung cancer tissue (1.479+/-2.060) and normal lung tissue (1.528+/-1.592, P=0.8267). There was no relationship between cten/GAPDH expression and age, gender or N-status. However, tumor/normal ratio (T/N ratio) of cten/GAPDH expression was significantly higher in stage II-IV lung cancer (3.113+/-6.493) when compared with stage I lung cancer (1.237+/-1.820, P=0.0316). T/N ratio of cten/GAPDH expression was significantly higher in T4 lung cancer (4.612+/-9.726) when compared with T1 lung cancer (0.896+/-0.860, P=0.0252), and T2 lung cancer (1.636+/-2.066, P=0.0470), respectively. Thus cten/GAPDH mRNA expression has been correlated with evidence of tumor progression in terms of T and overall stage of lung cancer. Alternatively, cell motility or migration might play a role in progression of lung cancer.
