title: Manganese superoxide dismutase expression as a function of genotype and lung cancer pathology.
abstract: BACKGROUND
  The aim of this study was to compare the manganese superoxide dismutase (MnSOD) expression in matched tumor and normal tissue.
  
  
  METHODS
  One hundred lung cancer specimens and matched normal lung parenchyma from the same patient were evaluated for MnSOD expression.
  
  
  RESULTS
  The median normal MnSOD expression was 42% with a range of 10 to 70%, which was significantly greater (p = .001) than the median MnSOD expression in the tumor samples that was 18.8% and ranged from 1.1 to 50%.
  
  
  CONCLUSIONS
  MnSOD expression is significantly reduced in lung adenocarcinoma and squamous cell carcinoma compared to the matched normal lung tissue.
