NA indicates not available; —, too few metaphases, no FISH data available; Δ, WHO high-risk patients were excluded from this analysis.
Morphologic diagnosis at presentation according to WHO classification.
Clinical follow-up of patients revealed whether the patients were non- or low transfusion dependent (N), highly transfusion dependent (T), or suffered from progressive disease (P; progression towards at least RAEB-1 within 18 months).
Results of flow cytometric analysis are summarized as follows: a single aberrancy is depicted in lower case representing a defined subpopulation of myelomonocytic cells: b for blasts, g for granulocytes and m for monocytes, multiple aberrancies are depicted in upper case (B, G and M), expression of lineage infidelity markers or CD34 (except for blasts) is depicted by underlining (B, G and M), expression of lineage infidelity markers within normal blast percentages is depicted as b, the lineage infidelity marker that is expressed on myeloid blasts is depicted between brackets.
Flow cytometric data are translated into a numerical MDS flow-score according to the flow cytometric scoring system by Wells et al12 : no aberrancy scores 0 points, a single aberrancy in either granulocytic or monocytic subpopulation scores 1 point, 2 or 3 aberrancies score 2 points, and additional points are given for abnormal myeloblasts, increased percentage of myeloblasts, and a decreased granulocyte-lymphocyte ratio.
Minimal IPSS or WPSS due to missing cytogenetics data.
