Acute myeloid leukaemia is staged by CNS involvement.
The AML — Toronto Stage is a oncology scoring tool used in paediatric practice. Acute myeloid leukaemia is staged by CNS involvement. It scores 1 criteria and interprets the total across 2 bands, so the number always arrives with the severity it implies rather than on its own. In PediAid each criterion is shown as a labelled option with the weight it carries, so the total can be checked rather than taken on trust.
1. They are CNS status at diagnosis.
The total is interpreted as: 1 stage or more - Stage I: stage I - no CNS involvement. Standard AML induction with intrathecal prophylaxis per protocol; 2 stage or more - Stage II: stage II - CNS involvement. Requires intensified CNS-directed intrathecal therapy alongside systemic treatment.
No. It is a structured way to record and communicate severity. A clinician concerned about a child should act on that concern regardless of the total.

Yes. Score definitions are bundled with the PediAid app, so the score computes without a connection.
