Staged by resection status and metastatic disease.
The Non-Rhabdomyosarcoma Soft-Tissue Sarcoma — Toronto Stage is a oncology scoring tool used in paediatric practice. Staged by resection status and metastatic disease. It scores 1 criteria and interprets the total across 4 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 Extent and resection status.
The total is interpreted as: 1 stage or more - Stage I: completely resected localised NRSTS - surgery alone may suffice in low-grade small tumours; 2 stage or more - Stage II: localised but incompletely resected - consider re-excision, radiotherapy and chemotherapy by grade; 3 stage or more - Stage III: regional nodal disease - multimodal therapy required; 4 stage or more - Stage IV: metastatic NRSTS - poor prognosis; chemotherapy sensitivity varies widely by histological subtype.
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.
