More than 5% blasts in bone marrow
Hi Deanne,
You know there are many types of MDS. Here are some figures that I got from a material of 1000 MDS patients in Germany:
Refractory anemia (RA or RARS) 15%
Refractory cytopenia with multilineage dysplasia 50%
RAEB-1 (<10% marrow blasts) 15%
RAEB-2 (10-19% marrow blasts) 15%
MDS associated with isolated del5q 5%
As you can see about 30% of these 1000 MDS patients had more than 5% blast cells in bone marrow. It is true that BMB is very important for MDS dx.
Kind regards
Birgitta-A
