| Abstract | 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. The relevant papers were selected according to some stringent inclusion criteria. Essential data were extracted from the recruited papers and further processed by systematic meta-analysis. The meta-analysis included 5 studies for diagnosis of colorectal cancer. Overall, the pooled sensitivity and specificity of all studies were 73% (95%CI=0.69-0.76) and 89% (95%CI=0.85-0.93). The pooled positive likelihood ratio and negative likelihood ratio were 5.41 (95%CI=3.85- 7.59) and 0.37 (95%CI=0.22-0.62). The pooled diagnostic odds ratios was 18.05 (95%CI=11.77-27.69). The area under the summary receiver operating characteristic curve for the diagnosis of colorectal cancer was 0.87. Meanwhile, 3 studies were included to evaluate the prognostic significance of NGAL overexpression in colorectal cancer patients. The pooled hazard ratio was 2.12 (95%CI=1.35-3.33). High level of NGAL predicted poor disease-free survival. Thus, NGAL is a potential biomarker for the diagnosis and prognosis of colorectal cancer. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
