| Abstract | PURPOSE OF REVIEW: Targeted molecular therapy is playing an increasingly important role in the treatment of nonsmall cell lung cancer (NSCLC). Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) have demonstrated efficacy in the advanced disease setting. Preliminary findings suggest that EGFR-TKIs may also be beneficial as adjuvant therapy following complete resection in patients with EGFR-mutation-positive early-stage I-III NSCLC; however, many questions remain unanswered. RECENT FINDINGS: Single-arm trials of adjuvant EGFR-TKI therapy in patients with tumors harboring activating EGFR mutations show impressive 2-year disease-free survival (DFS). Phase III randomized trial data do not support adjuvant EGFR-TKI therapy in unselected completely resected stage I-III NSCLC, but show improved DFS in patients with completely resected EGFR-mutated NSCLC. Adverse events leading to treatment withdrawal and dose reductions are frequent with adjuvant EGFR-TKI therapy, and relapse following treatment withdrawal is common. Adjuvant EGFR-TKIs have not yet been shown to improve the overall survival (OS) in patients with tumors harboring activating EGFR mutations. SUMMARY: There are no data to support the use of adjuvant EGFR-TKIs in unselected early-stage NSCLC. Although EGFR-TKIs hold promise as adjuvant therapy in patients whose tumors harbor EGFR mutations, in the absence of definitive data confirming an OS benefit eligible patients should continue to receive adjuvant chemotherapy following complete resection. |

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.
