Clinical significance of neutrophil gelatinase-associated lipocalin (NGAL) in colorectal cancer: a meta-analysis
Growing evidence has implicated that neutrophil gelatinase-associated lipocalin (NGAL) plays a role in a spectrum of human cancers. Several observational studies from different parts of the world have been devoted to elucidate the clinical relationship between NGAL and colorectal cancer. This meta-analysis aimed to explore the overall accuracy of NGAL detection for the diagnosis and prognosis of colorectal cancer. Based on comprehensive literature screening on Pubmed, Ovid, and CNKI databases, our screening covered all published papers until March 2013.
