PG - 77-81 AB - Specific genetic abnormalities are of prognostic significance for patients with chronic lymphocytic leukemia (CLL) and multiple myeloma (MM); however, routine cytogenetic analysis usually provides normal results. We utilized two probe panels for interphase fluorescence in situ hybridization (FISH) studies to enhance the ability to detect genetic abnormalities in samples that were referred for routine cytogenetic studies for possible diagnoses of CLL or MM. The CLL panel consisted of probes for 11q22.3 (ATM gene), 13q14 (D13S319), the centromere of chromosome 12 (D12Z3) and 17p13.1 (P53 gene). The MM panel included probes for 14q32 (IgH gene) and/or t(11:14)(q13;q32) (BCL1/IgH), 13q14 (D13S319) and 17p13.1 (P53 gene). FISH detected clonal aberrations not identified by conventional cytogenetics in an additional 8 of 23 (35%) samples referred for possible CLL and 7 of 42 (17%) samples with possible MM. The prognostic significance of the aberrations identified ranged from favorable, to intermediate, to poor. Our studies indicate that many samples referred for routine cytogenetics testing for CLL and MM yield normal results for both conventional and FISH testing, likely due to lack of definitive diagnosis in a percentage of cases. However, FISH is more sensitive for the detection of clinically significant chromosome abnormalities and should be the testing methodology of choice for these disorders.
