Brief Summary
In myelodysplastic syndromes (MDS) the knowledge about chromosomal aberrations is important for diagnosis, pathogenesis, prognosis and treatment. Usually, chromosomal anomalies in MDS patients are detected in bone marrow cells by chromosome banding analyses of metaphases. Alternatively or additionally they can be diagnosed by Fluorescence-in-Situ-Hybridization (FISH). The investigators here present a novel method for cytogenetic monitoring of MDS patients from peripheral blood which is representative for the clone size in bone marrow cells. The purpose of this prospective multicenter non-interventional diagnostic study is to detect and to follow chromosomal aberrations from peripheral blood closely, to assess karyotype evolution, to detect rare abnormalities and to correlate the molecular-cytogenetic results with peripheral blood counts, bone marrow morphology and treatment modalities and responses.

Outcome Measures
Primary Outcomes (1)
Screening and genetic monitoring of patients with MDS under different treatment modalities by cytogenetic analyses of circulating CD34+cells.
At each timepoint of FISH analysis the percentage of aberrant interphase nuclei is measured of all (at least 200) interphase nuclei counted.
The first FISH analysis is performed at the time of study entry (initial screening) and after that every 2 months in the first year and every 3 months in the second and third year.
Eligibility Criteria
20 ml of peripheral blood (pb) of a MDS patient are enriched by immunomagnetic cell sorting (by MACS® system). A FISH analysis is performed on these CD34+ cells according to product protocols using the FISH probe panels described above. The percentage of aberrant interphase nuclei (IN) is measured related to all (at least 200) IN counted. FISH analyses are performed every 2 months in the 1st and every 3 months in the 2nd and 3rd year of follow-up by the same method using the standard panel and, if necessary, an informative probe of the super panel. Pb counts are documented once a month, and full blood counts with peripheral blasts are recommended at the time point of each FISH analysis. Bone marrow (bm) biopsies are not part of the study, but they are recommended to be performed every 6 to 12 months. If a bm biopsy is performed, conventional chromosome banding analyses on bm metaphases and FISH analyses of enriched CD34+ and non-enriched bm cells are performed.
You may qualify if:
- Clinical diagnosis (cytomorphologic proof) of primary or secondary myelodysplastic syndrome (MDS) or
- Suspected myelodysplastic syndrome (MDS).
- Age \> 18 years
