A. Ambrosetti et al., EARLY LYMPHOID BLASTIC CRISIS FOLLOWING MAJOR KARYOTYPIC CONVERSION IN A CHRONIC MYELOID-LEUKEMIA PATIENT TREATED WITH INTERFERON-ALPHA, International journal of clinical & laboratory research, 24(1), 1994, pp. 58-59
A major karyotypic conversion following interferon-alpha treatment del
ays or prevents blastic crisis in patients with chronic myeloid leukem
ia. We report here a 12-year-old boy with Ph1+ chronic myeloid leukemi
a who, after achieving a major karyotypic conversion following 12 mont
hs interferon-alpha treatment, developed an early lymphoid blastic tra
nsformation 7 months later while still under interferon-alpha therapy.
A number of possible explanations for this quite unexpected event are
discussed.
