摘要
The clone size has been postulated as a prognostic factor in myelodysplastic syndromes (MDS), though it has not been studied systematically. We tested its impact (< 100% vs. 100%) in a population of 216 MDS with chromosome 7 abnormalities (-7/7q-) (n = 84), trisomy 8 (n = 99), 20q deletion (n = 28) and loss of Y chromosome (n = 26). Focusing on the survival the bad prognosis of -7/7q- was independent of the clone size (9.3 vs. 5.0 months, P = 0.188, not significant) but trisomy 8 cases with 100% aberrant metaphases did reveal a worse prognosis (13.9 vs. 5.9 months, P = 0.003).
