Peripheral blood leukocyte mitochondrial DNA content and risk of lung cancer.

ABSTRACT:

Background

Previous studies of peripheral blood leukocyte mitochondrial DNA (mtDNA) content and risk of lung cancer have yielded inconsistent results, and no studies have evaluated the association between mtDNA content and post-resection lung cancer outcomes.

Methods

Using a case-control study design, we evaluated the association between mtDNA content and risk of lung cancer in 465 cases and 378 controls. We also evaluated the association between mtDNA content and survival in 189 cases with surgically resected non-small cell lung cancer (NSCLC). Relative mtDNA content was measured using a quantitative real-time polymerase chain reaction (PCR) assay in peripheral blood genomic DNA. We calculated odds ratios (ORs) and 95% confidence intervals (CIs) using multivariable logistic
