PG - 542-5 LID - 10.3760/cma.j.issn.0253-2727.2014.06.015 [doi] AB - OBJECTIVE: To evaluate the three-probe fluorescence in situ hybridization (FISH) panel in the diagnosis of pediatric B cell acute lymphoblastic leukemia (B-ALL). METHODS: Three-probe (TELAML1, BCR-ABL and MLL) FISH and conventional cytogenetic analysis were performed in 207 children with B-ALL. RESULTS: In 207 B-ALL children, the three-probe FISH panel assay showed that 151 cases carried genetic aberrancies with a positive rate of 72.9%, including 44 cases with typical positive signal patterns and 148 cases with atypical signal patterns (among them 41 cases have multiprobe abberancy). The conventional cytogenetic analysis detected 53 cases chromosomal abnormality with a positive rate of 25.6%. CONCLUSION: The detection rate of genetic abnormalities in newly- diagnosed pediatric B-ALL could be significantly improved by using three-probe FISH panel upon conventional cytogenetic analysis.
