PG - 103-7 AB - In the present study, three chronic myelogenous leukemia (CML) patients with variant Philadelphia (Ph) chromosomes (complex types), two CML patients with a masked Ph, one case with Ph positive acute lymphocytic leukemia (ALL), and one with Ph positive acute myelocytic leukemia (AML) were analyzed by standard cytogenetic techniques (G-banding), Southern blot studies, and fluorescence in situ hybridization (FISH) procedures using probes from portions of the bcr and abl genes. It has been previously shown that this FISH approach could detect the bcr/abl fusion event in CML patients with classic or variant (simple type) Ph. Our results demonstrate that this FISH assay can also detect the bcr/abl fusion status in CML patients with masked or variant (complex type) Ph chromosomes and in some patients with Ph positive ALL or AML.
