| Abstract | BACKGROUND: CD56 is generally considered to be a natural killer (NK) cell marker, but it is also found in various tissues including acute leukemia. Recently, some reports have showed that positive CD56staining by blast cells is associated with an unfavorable outcome in AML with either t(8;21) or t(15;17)and in some ALL. This study investigated the characteristics of morphology, immunophenotype and cytogenetics and correlated the expression of CD56 of blast cells in 262 acute leukemia patients. METHODS: We analyzed 153 AML and 109 ALL, who underwent flow cytometry for CD56 at diagnosis at Chonnam National University Hospital between January 1999 and May 2003, for morphology, immunophenotype, and cytogenetics, retrospectively. RESULTS: The CD56 antigen was positive in 47 out of 163 AML cases (28.8%) and in 4 out of 109 ALL cases (3.7%). There were no statistically significant differences in the hematological parameters between the CD56+ and CD56- groups in ALL. However, the CD56 expression in AML was significantly high (81.8%) in AML-M2 with t(8;21) and low (5%) in AML-M3 with t(15;17) and was associatedwith the frequent expression of CD34 and HLA-DR. CONCLUSIONS: In conclusion, the CD56 expression in AML is associated with specific translocation, FAB subtype, some antigens CD34 and HLA-DR, and is significantly higher than in ALL. |

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.
