Worked calculation
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.
| Local tumor extent | IA1 — stromal invasion ≤ 3 mm (microscopic) |
|---|---|
| Nodal metastasis (imaging r or pathology p) | None |
| Bladder/rectal mucosa or beyond true pelvis | No |
| Distant metastases | No |
→FIGO stageIA1
- FIGO 2018：IA1 (stromal invasion ≤ 3 mm)
- Management direction：Conization or extrafascial hysterectomy; fertility preservation possible if LVSI-negative and margins clear; LVSI+ → consider pelvic nodal assessment
- Note：FIGO 2018 incorporates imaging (r) and pathology (p); any positive node → IIIC; stage IA requires microscopic assessment of the entire lesion
| Local tumor extent | IIIB — pelvic wall / hydronephrosis |
|---|---|
| Nodal metastasis (imaging r or pathology p) | Para-aortic nodes (→ IIIC2) |
| Bladder/rectal mucosa or beyond true pelvis | Yes (→ IVA) |
| Distant metastases | Yes (→ IVB) |
→FIGO stageIVB
- FIGO 2018：IVB (distant metastases)
- Management direction：Systemic therapy (platinum ± bevacizumab ± checkpoint inhibitor if PD-L1+) ± palliative radiation
- Note：FIGO 2018 incorporates imaging (r) and pathology (p); any positive node → IIIC; stage IA requires microscopic assessment of the entire lesion
Common questions
What is Cervical cancer FIGO 2018 staging?
Assign the FIGO 2018 cervical cancer stage from local extent, nodal status, adjacent-organ and distant spread, with a stage-specific management direction. Instant, browser-side.
How is Cervical cancer FIGO 2018 staging calculated? What is the core formula?
Highest level of involvement defines the stage: IA microscopic (≤ 3 / > 3–5 mm) → IB by size (≤ 2 / 2–4 / > 4 cm); II beyond uterus (IIA vagina / IIB parametria); III lower vagina (IIIA), pelvic wall/hydronephrosis (IIIB), pelvic nodes (IIIC1) / para-aortic (IIIC2); IVA mucosa/beyond pelvis, IVB distant.
When is Cervical cancer FIGO 2018 staging used?
Staging and first-line management direction for cervical cancer using the FIGO 2018 system (which incorporates imaging and pathology).
What are the key clinical points for Cervical cancer FIGO 2018 staging?
A key 2018 change: any nodal metastasis (any size, imaging r or pathology p) upstages to IIIC, recorded with an r/p notation. IB is subdivided by size (≤ 2 / > 2–4 / > 4 cm) into IB1/IB2/IB3 — a 2018 refinement over the older IB1/IB2 split. Early disease (≤ IIA1) is mainly surgical; IB3 and locally advanced disease are mainly concurrent platinum chemoradiation + brachytherapy. Fertility-sparing options exist for selected IA–IB1 disease.
What are the limits and cautions when using Cervical cancer FIGO 2018 staging?
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.
How is Cervical cancer FIGO 2018 staging calculated in practice? Can you show a worked example?
