TCCSG L92-13 study• Tokyo Children’s Cancer Study Group• Designed to test the hypothesis;
- “Intensified consolidation might reduce leukemic cell burden sufficiently to allow shortening of maintenance therapy.”
• Conducted in 1992 - 1995• Newly diagnosed ALL (1-15y)• n = 347 (non T-ALL 308, T-ALL 39)
All treatment was discontinued at 1 year after Dx, and duration of maintenance therapy; 4-6 months

Outcome of L92-13 study
EFS OS
• EFS 59.5%@5.5y (median f/u: 4 years)(6yEFS: 68.7% in L89-12 study)
• Conclusion: maintenance for 6m was not adequate.Toyoda Y et al. J Clin Oncol 2000

• To confirm long-term outcome of ALL with short maintenance therapy.
- true cure or late relapse?
• 347 pts enrolled in L92-13- a median follow-up period of surviving pts;
17.1y(0.25-21.8y)
An extended follow-up study; L92-13E

Which patients require standard maintenance?
Boys require standard maintenance.
Immunophenotype and early response could not predict those who require standard maintenance.

Summary
• JPLSG B12 study was closed.- First nation-wide study in children- 2000 patients- improved outcome
• JCCG B19 study will open soon.- Age up to 65- Reduce treatment for selected LR- Blinatumomab in first line treatment- Optimization of duration of maintenance therapy

MRD based stratification
• In T11 study all patients were stratified by PCR-MRD because patient number was relatively small
• In B12 study PCR-MRD was used only to decide SCT indication in HR patients
• In mid 2018 PCR-MRD was approved by government and will be available for all ALL patients in December
