Chronic lymphocytic leukemia is the most common chronic lymphoproliferative disorder in Spain. The clinical management of this entity varies widely.

Incidence and characteristics of myelodysplastic syndromes in Ourense (Spain) between 1994-1998.

The very few reference epidemiological studies on myelodysplastic syndromes (MDS) have been carried out in Europe: Germany, France, UK and Sweden. We present the first Spanish study on the incidence and characteristics of MDS. The incidence rates, distribution by FAB subtypes, sex and age groups are within the ranges established by the reference studies with minimal differences which we point out and attempt to explain.
