Favourable outcome in an APL patient with PLZF/RARalpha fusion gene: quantitative real-time RT-PCR confirms molecular response.
Rare cases of acute promyelocytic leukemia (APL) are associated with a t(11;17) translocation and a PLZF-RARalpha fusion transcript. Because of molecular specificities of the fusion protein, ATRA efficiency is often reduced in these cases. We present herein the case of an 83-year old patient which has been successfully treated by ATRA and Daunorubicin. The described quantitative RT-PCR method allowed successful monitoring and confirmation of the molecular response.
