| Abstract | Endocrine therapy of breast cancer is perhaps the oldest form of effective and well-tolerated targeted cancer systemic treatment, in both the adjuvant and metastatic disease settings. The most commonly used endocrine therapy agents are selective estrogen receptor modulators, aromatase inhibitors, and selective estrogen receptor downregulators. De novo or acquired resistance to these agents is a significant clinical problem. Preclinical and clinical investigations to understand this resistance have yielded significant advances in understanding cell signaling and the possible mechanisms of resistance. These mechanisms of resistance are as diverse as the biology of breast cancer and can arise from alterations in any of the cell signaling pathway components. A growing understanding of these mechanisms has provided rationale for development of strategies to overcome the resistance. Many of these mechanisms of resistance involve adaptive upregulation of alternate signaling pathways, such as growth factor signaling, and cross talk between estrogen receptor and growth factor signaling. Clinical trials are focusing on cotargeting these alternate pathways along with estrogen receptor signaling. It is becoming evident that, as with all cancer therapy, strategies to overcome resistance need to be individualized, and it is important to identify biomarkers to guide the use of these strategies. This manuscript systemically reviews the recent preclinical and clinical trials on the novel and pathway-driven agents that have shown significant promise in enhancing the efficacy and overcoming the resistance in the hormonal treatment of breast cancer. Future directions including biomarker selection and the role of next generation sequencing will be discussed. |

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.
