Abstract

Lung cancer is the leading cause of cancer death in men and the second leading cause of cancer death in women worldwide. FGFR is involved in a variety of cellular processes including angiogenesis, wound healing, tissue repair, and tumorigenesis. Recently, a common polymorphism in the transmembrane domain of the FGFR4 gene, Gly388Arg, has been reported to correlate with alteration of cell migration in vitro and with disease progression and/or survival in breast, colon, prostate and lung cancer. To evaluate the prognostic significance of the FGFR4 Gly388Arg polymorphism in lung cancer, we analyzed a case-control study of 110 lung cancer patients and 90 healthy control. Genomic DNA from whole-blood specimens was extracted using Salting-out method. Quality of DNA was evaluated by electrophoresis. To determine the distribution of FGFR4 Arg388 and FGFR4 Gly388 alleles in lung carcinoma patients, RFLP-PCR was used. In this study demonstrated that there was no relationship between polymorphism of FGFR4 Gly388Arg gene and lung cancer. Also, no significant relationship was observed between this polymorphism and clinical and pathological features of patients. It is suggested that the large casecontrol studies are needed to detect genetic determinants affecting patients’ prognosis, with the promise of targeting these putative genetic determinants to provide new therapeutic tools for patients with lung cancer.
