Introduction: A number of genome-wide association studies (GWASs) have identified chromosomal regions containing genes associated with the risk of lung cancer. Genetic polymorphisms influence not only the development of cancer, but also cancer progression and prognosis. Therefore, we investigated the impacts of genetic variants associated with susceptibility to lung cancer in GWASs on the prognosis of NSCLC. Materials and Methods: This study included patients (n=363) with stage I, II, or IIIA (micro-invasive N2) NSCLC who under-went curative surgical resection at the Kyungpook National University Hospital, Daegu, Korea between September 1998 and December 2007. Eight single nucleotide polymorphisms (SNPs) in the six chromosomal regions (CRP rs2808630, FAM13A rs7671167, HHIP rs1489759, GYPA rs2202507, TERT rs2736100, CLPTM1L rs402710, BAT3 rs1052486, and CHRNA5 rs16969968) were genotype by a PCR-RFLP analysis. Results: None of the eight SNPs were significantly associated with overall survival and disease-free survival. In addition, when the patients were categorized according to age, gender, smoking status, tumor histology and pathologic stage, there were no significant associations between the eight SNPs and survival outcomes. Conclusions: These results suggest that the genetic variants identified by GWASs for lung cancer susceptibility are not sig-nificantly associated with the prognosis of patients with early stage NSCLC.
