Ovarian Tumour — Toronto / FIGO Stage

Paediatric ovarian (usually germ-cell) tumour staging.

1 What is the Ovarian Tumour — Toronto / FIGO Stage?

The Ovarian Tumour — Toronto / FIGO Stage is a oncology scoring tool used in paediatric practice. Paediatric ovarian (usually germ-cell) tumour staging. 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.

2 When to use it

  • Grading severity at the bedside in oncology
  • Recording an objective severity band in the case notes
  • Deciding when a total crosses the threshold for escalation
  • Re-scoring to track whether a child is improving or deteriorating
  • Checking the exact criteria of a score used infrequently

3 Formula & method

The score sums 1 criteria: Extent of disease. Totals are then banded: 1 stage or more - Stage I: stage I - surgery alone with surveillance is often sufficient for germ-cell tumours; excellent prognosis; 2 stage or more - Stage II: stage II - surgery plus platinum-based chemotherapy; 3 stage or more - Stage III: stage III - surgery plus chemotherapy; monitor tumour markers (AFP, β-hCG) for response; 4 stage or more - Stage IV: stage IV - distant metastases. Platinum-based chemotherapy; germ-cell tumours remain highly curable even at this stage.

4 Frequently asked questions

How many criteria does the Ovarian Tumour — Toronto / FIGO Stage use?

1. They are Extent of disease.

What do the bands of the Ovarian Tumour — Toronto / FIGO Stage mean?

The total is interpreted as: 1 stage or more - Stage I: stage I - surgery alone with surveillance is often sufficient for germ-cell tumours; excellent prognosis; 2 stage or more - Stage II: stage II - surgery plus platinum-based chemotherapy; 3 stage or more - Stage III: stage III - surgery plus chemotherapy; monitor tumour markers (AFP, β-hCG) for response; 4 stage or more - Stage IV: stage IV - distant metastases. Platinum-based chemotherapy; germ-cell tumours remain highly curable even at this stage.

Does the score replace clinical judgement?

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.
