PG - 45-9 AB - Fluorescence in situ hybridization (FISH) using specific probes for the 5q31-32 region and a whole chromosomal painting (WCP) probe for chromosome 5 were used to corroborate the results of classical cytogenetic examinations performed on G-banded chromosomes of 77 patients with hematological malignancies. Using classical cytogenetic methods, we suspected the presence of clones with a deletion 5q in 63 patients, and complex rearrangements with involvement of chromosome 5 in 14 other cases. Fluorescence in situ hybridization proved the occurrence of deletion 5q31 in 23 patients and ascertained translocations of part of the long arms of deleted chromosome 5 with missing region 5q31 in 12 patients. In 2 cases, the 5q31 region was translocated to other chromosomes as a part of complex rearrangements. The combination of classical cytogenetics and FISH with specific probes for the 5q31 band yielded cytogenetic results in 35 cases. Routine FISH detection of deleted regions was possible by commercially available cosmid probes for the 5q31 chromosomal band. The interpretation of small deletions and frequent involvement of the deleted chromosomes 5 in complex translocations were ascertained by WCP probes.
