The proposed minimal diagnostic criteria for myelodysplastic syndromes (MDS) and potential pre-MDS conditions has been released by an international consensus group. Based on the criteria, patients with persistent cytopenia could be diagnosed with MDS, CCUS and ICUS. However, the process and outcome of pre-MDS conditions (CCUS, ICUS) is still to be characterized in Chinese population. We design this prospective observational study to explore the disease process and outcome in ICUS and CCUS patients.

Culumative transformation rate
Transformation is defined as progression from ICUS to CCUS, ICUS to MDS or CCUS to MDS. All patients are followed-up since entry into this trial and transformation events are recorded. Cumulative transformation rate is defined for all patients and estimated by competing risk methods.
Time frame: 5 years
