Hypoxia pathway genetic variants predict survival of non-small-cell lung cancer patients receiving platinum-based chemotherapy.

ABSTRACT: Hypoxia is a hallmark of solid tumors and has been implicated in the development of advanced disease and poor clinical outcome. In this multi-stage study, we aimed to assess whether genetic variations in hypoxia pathway genes might affect overall survival (OS) in patients with advanced-stage non-small cell lung cancer (NSCLC). We genotyped 598 potentially functional and tagging single nucleotide polymorphisms (SNPs) in 42 genes of the hypoxia pathway in 602 advanced stage NSCLC patients who received platinum-based chemotherapy or chemoradiation (discovery phase). Significant SNPs were validated in an additional 278 advanced stage patients (validation phase). Cox proportional hazard regression analysis was used to evaluate the association of each SNP with OS. Results showed in chemotherapy
