Methodology · worked example, guidelines & full notes
Clinical takeaway

Low risk → single-agent (methotrexate/actinomycin D).

When to use

Decide between single-agent and combination chemotherapy in GTN.

How it works

Sum 8 factors (age, antecedent pregnancy, interval, hCG, tumor size, metastatic site, number of metastases, prior failed chemo). ≤ 6 low risk, ≥ 7 high risk.

Key points

  • Low risk → single-agent (methotrexate/actinomycin D).
  • High risk → combination chemotherapy (e.g. EMA-CO).
  • Expressed with the FIGO anatomic stage; not for PSTT/ETT.

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

→FIGO score8

  • Prognostic score:8 → High risk (≥ 7)
  • Treatment:High-risk GTN: combination chemotherapy (e.g. EMA-CO), salvage and multidisciplinary care as needed; individualized treatment for brain/liver metastases
  • Note:Expressed with the FIGO anatomic stage (e.g. III:5); does not apply to PSTT or epithelioid trophoblastic tumor

→FIGO score0

  • Prognostic score:0 → Low risk (≤ 6)
  • Treatment:Low-risk GTN: single-agent chemotherapy (methotrexate or actinomycin D); switch agent or escalate if resistant
  • Note:Expressed with the FIGO anatomic stage (e.g. III:5); does not apply to PSTT or epithelioid trophoblastic tumor

Frequently asked questions

What are the limits and cautions when using GTN WHO/FIGO Prognostic Score?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
Does GTN WHO/FIGO Prognostic Score upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
