Abstract:

Objective

To investigate the expression of EFhd1 and its potential value as a prognostic indicator of survival in the patients with primary non-small cell lung cancer (NSCLC).

Methods

A total of 178 NSCLC tissue specimens and 51 paracancerous tissue specimens were collected from 178 NSCLC surgical patients from January 2004 to April 2011 in the Cardiothoracic Surgery Department of the Affiliated Hospital of Nantong University. The clinical data and follow-up data were collected, too. Immunohistochemical analysis with tissue microarray was used to characterize the expression of EFhd1 in the NSCLC tissues. The relationship between the EFhd1 expression and the clinical characteristics and prognosis was determined by statistical analysis.

Results

The level of EFhd1 expression was higher in the NSCLC tissues than in the paracancerous tissues (P<0. 05). The EFhd1 expression in the NSCLC tissues was related to the T staging (P<0.05). Univariate analysis revealed that TNM stage, T stage and N stage were associated with the prognosis of NSCLC (P<0.01). Kaplan Meier survival and Cox regression analyses revealed that the higher level of EFhd1 expression (P=0.037) and later stage grouping by TNM (P=0.001) were independent factors predicting poor prognosis for the patients with NSCLC.

Conclusion

The level of EFhd1 expression in the NSCLC tissues is significantly higher than that in the adjacent tissues. Our finding provides the first evidence that the higher level of EFhd1 expression is associated with the poor prognosis of the patients with NSCLC.
