7.  Outcome After First Relapse in Children With Acute Lymphoblastic Leukemia:A Report Based on the Dutch Childhood Oncology Group (DCOG) Rel apse ALL 98 Protocol

9. Conclusions. Our data suggest the superiority of SCT for early relapse patients. For late relapses a better outcome is achieved with chemotherapy only using the rotational chemotherapy scheme. The most important factor for survival was interval between first CR and occurrence of the first relapse. Pediatr Blood Cancer. 2011;57:210–216. 2011 Wiley-Liss, Inc.

10.  Outcome of Childhood Acute Lymphoblastic Leukemia With Induction Failure Treated by the Japan Association of Childhood Leukemia Study (JACLS) ALL F-Protocol

11. The aim of this prospective study was to evaluate the efficacy and safety of the Japan Association of Childhood Leukemia Study (JACLS) ALL F-protocol on the outcome of childhood ALL with IF. This protocol consists of AML-oriented re-induction and consolidation block therapies followed by allogeneic HCT.

13. Patients obtaining CR by the end of the first consolidation therapy were scheduled to receive HCT after the second consolidation therapy but before maintenance therapy Maintenance therapy consisted of three alternating blocks for 18 months (Supplemental Table I).

16. In conclusion, the F-protocol consisting of AML-oriented block therapies followed by allogeneic HCT can improve the prognosis for non-Ph ALL patients with IF. However, to improve the chemotherapy regimen of the F-protocol we plan close MRD monitoring in future studies.
