| Abstract | Triple-negative breast cancer (TNBC) has a poor prognosis and lacks prognostic indicators. The androgen receptor (AR) and E-cadherin are involved in the pathogenesis of breast cancer, but their roles are not clearly defined. We designed this study to evaluate AR and E-cadherin expression and to determine their relationships with the clinicopathologic parameters of triple-negative breast cancer. The present study included 127 TNBC patients. Immunohistochemical stains for AR and E-cadherin were performed, and the relationships between AR and E-cadherin expression and clinicopathologic data and prognosis were analyzed. We found that in TNBC patients, AR was expressed in 16(12.6%) cases, and E-cadherin was expressed in 41(33.0%) cases. AR expression was associated with tumor grade (P = 0.004) and menopausal status (P = 0.017), and E-cadherin expression was associated with node status (P= 0.016). A multivariate analysis demonstrated that tumor size, tumor grade, lymph node status, and E-cadherin were of prognostic significance for disease-free interval and overall survival. Compared with AR-positive patients, AR-negative patients showed significantly poorer outcomes with respect to the disease-free interval (P = 0.047) and overall survival (P = 0.038). E-cadherin-negative patients experienced shorter disease-free interval (P = 0.016) and poorer overall survival (P = 0.012) than did E-cadherin-positive patients. An AR-positive and E-cadherin-negative expression profile was associated with recurrence or metastasis (P = 0.036). Moreover, as the expression of nuclear AR increased (25% vs. 33.3%, P = 0.361), less E-cadherin staining was observed in TNBC samples. This finding suggested that AR and E-cadherin expression could be a useful prognostic marker for classifying subgroups of TNBC. |

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.
