Scientific titleProtocol for treatment and research of acute lymphoblastic leukaemia of childhood of the Dutch childhood oncology group
Study objectivesThe dutch ALL-6 protocol (1984 - 1988) for standard risk childhood Acute Lymphoblastic Leukaemia (ALL) was one of the first to use dexamethasone as a steroid instead of prednisone. This led to surprisingly good results. The ALL-9 protocol thus was meant to reproduce these results and to extend the use to patients with high risk ALL.

This reduced intensity protocol is instituted to:
1. Confirm the data obtained in the SNWLK-ALL-6 protocol for standard risk patients
2. Offer significant improvement of cure rate in high risk patients, comparable to international childhood ALL protocols
3. Offer the possibility to conduct window studies with monotherapy
4. Validate the prognostic significance of in vitro drug resistance testing
5. Standardise the minimal residual disease test
6. Evaluate the side effects, especially osteonecrosis and psychological effects of dexamethasone
