A. Fasanaro et al., EARLY ELASTIC TRANSFORMATION OF A MYELOPROLIFERATIVE DISORDER WITH T(8-21) AND PROGRESSIVE ABERRATIONS OF CHROMOSOME-8, Cancer genetics and cytogenetics, 75(2), 1994, pp. 106-110
We describe a case of a patient affected by a chronic myeloproliferati
ve disorder with t(8;21)(q22;q22) and trisomy 8 at diagnosis. At the t
ime of blastic metamorphosis, 2 months later, trisomy 8 metaphases wer
e significantly reduced, while a predominance of t(8;21) was present.
Finally, in the phase of leukemic regrowth following chemotherapy admi
nistration, monosomy 8 associated with der(21)t(8;21) was the predomin
ant cytogenetic abnormality.
