  1. NGAL=neutrophil gelatinase-associated lipocalin; PanIN=pancreatic intraepithelial neoplasia.
  2. NGAL expression in the PanIN lesions adjacent to the areas of pancreatic cancer was calculated. The average composite score for PanIN lesions of a given grade was then calculated.
  3. aN represents the number of tissue specimens containing PanIN lesions of a given grade.
  4. bThe difference in the composite score between PanIN-1, -2, and -3 stages was statistically significant: P<0.004.
