Hypothesis

Is gemtuzumab ozogamicin effective and tolerable for children with relapsed or refractory myeloid leukemia?

Conclusion

Gemtuzumab ozogamicin shows a 25% response rate in children with relapsed or refractory myeloid leukemia, warranting further investigation.

Supporting Evidence

  • Three complete responses were observed in 12 patients, indicating a 25% response rate.
  • Adverse events included hematological toxicity in all patients, with one major adverse event.
  • Only one patient was alive at the end of follow-up, highlighting the poor prognosis.

Takeaway

This study tested a medicine called gemtuzumab ozogamicin in kids with a tough type of leukemia, and it helped some of them get better.

Methodology

Retrospective multicenter study of 12 children treated with gemtuzumab ozogamicin on a compassionate basis.

Limitations
