Exclusion criteria
Exclusion criteria: - Patients with a clinical diagnosis of APL but subsequently found to have PLZF-RARα fusion or lacking PML-RAR, NPM-RAR or NuMA-RAR rearrangement should be withdrawn from the study and treated on an alternative protocol. - Refractory/relapsed APL (the guidelines in this protocol for that subgroup are intended for patients treated from initial diagnosis according to this protocol) - Concurrent active malignancy - Pregnant or lactating - Physician and patient/guardian think that intensive chemotherapy is not an appropriate treatment option - Patients who have received alternative chemotherapy for 7 days or longer without ATRA for any reason (either APL not initially suspected or ATRA not available).
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: - to conduct an international pediatric study for APL with optimal outcome and less toxicity - to reduce cumulative anthracycline dosage - to deliver risk stratified treatment based on modified Sanz criteria - to monitor minimal residual disease by RQ-PCR for PML-RARα and adjust treatment accordingly;Secondary Objective: - To monitor cardiotoxicity by echocardiography;Primary end point(s): - Achievement of molecular complete remission (CRm) and reasons for failure - duration of remission, rates of molecular and frank relapse and deaths in first CR - Overall survival - Toxicity - hematological and non-hematological - Supportive care requirements | — |
