We report three cases of T-ALL in which conventional cytogenetic analysis yielded normal karyotypes, but for which a new M-FISH technique (IPM-FISH) was able to detect a translocation. For these patients this technique highlighted a new, recurring and cryptic translocation t(5;14)(q35;q32) in childhood T-ALL which might be phenotypically restricted. The most innovative part of this technique is the use of interspersed polymerase chain reaction (IRS-PCR) painting probes that show an R-band pattern simultaneous with the combinatorial labeling. Contrary to the DOP-PCR, IRS-PCR-derived probes provide stronger hybridization signals at the telomeric ends that potentially increase the possibility of detecting cryptic translocations. All the IPM-FISH findings were validated by FISH with whole chromosome painting and unique sequence probes. These results demonstrate the efficient use of IPM-FISH as an improved, single-step method for the identification of cryptic chromosomal abnormalities. This new IPM-FISH technique is a good tool to display cryptic chromosomal abnormalities.
