GTN FIGO Anatomic Stage
Extent of disease
When to use
Anatomic staging of GTN, used jointly with the prognostic score to guide single-agent vs combination chemotherapy.
How it works
I confined to uterus; II outside uterus but limited to genital structures (adnexa/vagina/broad ligament); III lung metastasis (± genital tract); IV other distant (brain/liver/kidney/GI). Expressed with the prognostic score as Stage:Score.
Key points
- Stage and prognostic score are reported together (e.g. III:7); stage alone does not determine treatment.
- GTN has no regional nodal staging — nodal disease is classed as M1b and is uncommon.
- Prognostic score ≤ 6 is low-risk (single-agent MTX/actinomycin D); ≥ 7 is high-risk (combination, e.g. EMA-CO).
- Even stage IV GTN has a relatively good prognosis compared with other solid tumours, especially lung-only disease.
