Abstract EN
Transformation to acute myeloid leukemia (AML) frequently occurs in patients with myelodysplastic syndrome (MDS), and genetic evolution probably plays a critical role in this transformation.
However, late appearance of the Philadelphia (Ph) chromosome during the course of transformed MDS is extremely rare.
We report a 77-year-old man with transformed MDS and an acquired Ph chromosome.
He was initially diagnosed with refractory anemia with 45,XY,del(5)(q?),-7,-14,-17,+mar1,+mar2 [7/20] as the major clone.
After 4 months, hematological studies showed progression of anemia with increased number of blast cells.
Conventional chromosome analysis revealed 45,XY,del(5)(q?),-7, t(9;22)(q34;q11.2),-14,-17,+mar1,+mar2 [20/20], a subclone with an acquired Ph chromosome derived from a stem clone observed at MDS diagnosis.
RT-PCR results were positive for major BCRABL transcript.
Although a comparison of whole-genome sequences between original and transformed clones would be informative, the acquired Ph chromosome probably played a role as a “class-I mutation,” which increases cell proliferation in transformed MDS.
