| Abstract | The aim of this study was to evaluate the diagnostic value of a grid of molecular genetic markers detectable in sputum and plasma samples of individuals enrolled in a lung cancer screening program with low-dose CT. Subjects enrolled in the baseline screening round of the ITALUNG (randomised) screening trial were invited to provide biological specimens for molecular analysis (1356 subjects out of 1406). We included 98 subjects in this analysis. There was a highly statistically significant difference between proportion of subjects with a negative baseline CT screening test who were positive to allelic imbalance, and those with a non-calcified nodule (NCN greater than or equal to 5mm), the reason of recall for all suspects at CT Scan (chi(2): 22.9; P<0.0001). Allelic imbalance showed good performance for screening of NCN > or = 5 mm. In subjects recalled for NCN > or = 5 mm, LOH, K-ras mutations and high levels of free plasma DNA (>5ng/ml plasma) might be important to support clinical decision making for further follow-up and repeated screening. This study, embedded in an early diagnosis randomised trial, suggests that a multi-screening approach integrating imaging technique and a biomolecular marker panel is worth of further investigation. |

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.
