LONG-STANDING REMISSION AFTER 25-OH D3 TREATMENT IN A CASE OF CHRONICMYELOMONOCYTIC LEUKEMIA

No side-effects were observed. A lthough vitamin D3 has been used in the treatment of myelodysplastic s yndromes, to our knowledge this is the first case of long-standing rem ission in a patient with CMML. This 'differentiation therapy' might be considered as a possible alternative in the management of this diseas e.
