Y. Kobzev et al., FLUORESCENCE IN-SITU HYBRIDIZATION STUDIES OF INTERPHASE NUCLEI FOR ASSESSING RESPONSE TO THERAPY IN PATIENTS WITH CHRONIC MYELOID-LEUKEMIA, Cancer genetics and cytogenetics, 106(2), 1998, pp. 128-134
We used two-color fluorescence in situ hybridization (FISH) to detect
BCR/ABL fusion in interphase nuclei in bone marrow of 17 patients with
chronic myeloid leukemia (CML) before and in the course of interferon
therapy. The results of FISH were compared with the data of conventio
nal cytogenetic investigation (G- or Q-banding) of the same specimens.
Changes in percentage of Ph-positive nuclei correlated with variation
s in percentage of Ph-positive metaphases. An overall difference in th
e classification of patients by conventional cytogenetics and FISH bas
ed on the percentage of Ph-positive cells was not observed. This FISH
method is reproducible, relatively easy to perform, and reliable for m
onitoring patients with CML. (C) Elsevier Science Inc., 1998.
