ABSTRACT
Purpose To investigate the sensitivity of BIOMED-2 primer system in T lymphoblastic lymphoma ( T-LBL) and acute lym-phoblastic leukemia ( ALL) patients immunoglobulin ( Ig) and T-cell receptor ( TCR) gene rearrangement, and to analyze the co-rear-rangement pattern. Methods Amplification of rearranged Ig and TCR gene was performed in standard PCR in 35 T-LBL/ALL pa-tients. PCR products were analyzed by heteroduplex and polyacrylamide gel electrophoresis. Results 16 cases (45. 7%) of 35 sam-ples were detected to have TCR gene rearrangements, including 6 cases (37. 5%) of TCRβgene monoclonal rearrangements, 4 cases (25. 0%) of TCRγ gene monoclonal rearrangements, 3 cases (18. 8%) of TCRβ and TCRγ gene double rearrangements, 2 cases (12. 5%) of TCRδ gene monoclonal rearrangements and 1 case (6. 3%) of TCRγand TCRδgene double rearrangements were detec-ted. 4 cases (11. 4%) of 35 samples detected to have clonal immunoglobulin and TCR gene rearrangements. 11 cases (39. 3%) of 28 T-LBL patients were detected to have TCR gene rearrangements, 6 cases (85. 7%) of 7 T-ALL have TCR gene rearrangements. Con-clusions BIOMED-2 multiplex PCR analysis strategy is a useful technique in the T-LBL patients.
