Abstract:
Purpose: The main prognostic factor of lung cancer patient outcome is clinical stage, a parameter of tumor aggressiveness. Our study was conducted to test whether germ line variations modulate individual differences in clinical stage.
Experimental Design: We conducted a case-only genome-wide association study (GWAS) using a 620,901 single-nucleotide polymorphism (SNP) array in a first series of 600 lung adenocarcinoma (ADCA)patients and in a replication series of 317 lung ADCA patients.
Results: GWAS identified 54 putatively associated SNPs, 3 of which were confirmed in the replication series. Joint analysis of the two series pointed to 22 statistically associated (P < 0.01) genetic variants that
together explained about 20% of the phenotypic variation in clinical staging (P < 2 10 16) and showed a
statistically significant difference in overall survival (P ¼ 8.0 10
8). The strongest statistical association was observed at rs10278557 (P ¼ 1.1 10 5), located in the mesenchyme homeobox 2 (MEOX2) gene.
Conclusion: These data point to the role of germ line variations involving multiple loci in modulating
clinical stage and, therefore, prognosis in lungADCApatients
