Role of reinduction
BFM group
• in high-risk patients
ALL-BFM 83 trial
• extended in low-risk patients
St. Jude 13B protocol
• 6-week reinductiontherapy in low-riskpatients: better treatment outcome
• 5-year EFS 88.7 ± 3% and OS 92.1 ± 2.6%.

Conclusion
• Two courses of reinduction treatment have not shown to be more beneficial than one course for SR patients in TPOG-ALL-2002 study.
• MRD-based therapy applied in current TPOG-ALL-2013 protocol
