Answer

In an earlier study by List et al, erythroid responses occurred in 57% of MDS patients with a normal karyotype, in 68% of those in the IPSS low-risk category, and 50% of those in the intermediate–1 risk category. [29]

Although the best responses have been observed in MDS patients with isolated 5q deletion, responses may also be elicited in patients with 5q deletion and other chromosomal abnormalities. However, treatment should be limited to patients without the p53 mutation. Thus, assessment of an additional molecular marker may be necessary before committing to this treatment in those patients.
