Interferon-alpha 2a therapy in CML: disappearance of BCR/ABL transcript in a case of long-lasting continuous cytogenetic conversion

Haematologica. 1994 Nov-Dec;79(6):540-1.

Abstract

Seventy months after diagnosis, minimal residual disease is undetectable in a patient with Philadelphia chromosome-positive chronic myelogenous leukemia (CML) in long-lasting continuous cytogenetic conversion (CCC), achieved through alpha 2a-interferon (IFN-alpha) therapy. Fluctuating molecular remission, evaluated with the two-stage reverse transcriptase-polymerase chain reaction (RT-PCR) with nested primers, has persisted for two years at the maximum tolerable dose of IFN alpha (1.5 x 10(6) IU per day).
