| Abstract | We aimed to evaluate the immunodiagnostic values of autoantibodies to a panel of six tumor-associated antigens (TAAs) in the detection of patients with breast cancer. This study determines whether a panel of multiple TAAs would enhance antibody detection and be a useful approach in breast cancer detection and diagnosis. The panel of multiple TAAs was composed of six TAAs including Imp1, p16, Koc, survivin, cyclin B1, and c-myc full-length recombinant proteins. Enzyme-linked immunosorbent assay (ELISA) was used to detect antibodies against these six TAAs in 49 sera from patients with breast cancer, 35 sera from patients with benign breast tumor, and 38 sera from normal individuals. Antibody frequency to any individual TAA in breast cancer was variable and ranged from 12.2 to 18.4 %. With the successive addition of TAAs to a final total of six antigens, there was a stepwise increase of positive antibody reactions reaching a sensitivity of 67.3 % and a specificity of 92.2 % in breast cancer. Positive and negative likelihood ratios were 8.52 and 0.36, respectively, which showed that the clinical diagnostic value of a parallel assay of six TAAs was high. Positive and negative predictive values were, respectively, 91.7 and 68.6 %, indicating that the parallel assay of six TAAs raised the diagnostic accuracy greatly. Agreement rate and kappa value were 78.1 % and 0.57, respectively, which indicated that the observed value of this assay had a middle range of coincidence with the actual value. The data from this study further support our previous hypothesis that the detection of autoantibodies for diagnosis of a certain type of cancer can be enhanced by using a panel of several carefully selected TAAs as target antigens and a panel of multiple TAAs would be a useful approach in the detection and diagnosis of breast 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.
