A 38-year-old woman is diagnosed with squamous cell carcinoma of the cervix. MRI shows a 5 cm tumour confined to the cervix with no parametrial involvement and no lymph node enlargement. According to FIGO 2018 staging, what stage is this?
- A Stage IB1
- B Stage IB3 ✓
- C Stage IB2
- D Stage IIA1
Correct answer: B. Stage IB3
Explanation
FIGO 2018 reclassified Stage IB into three subcategories: IB1 (< 2 cm), IB2 (2–< 4 cm), and IB3 (≥ 4 cm), all confined to the cervix. A 5 cm tumour confined to the cervix is Stage IB3. Stage IIA involves upper two-thirds of vagina without parametrial involvement. This reclassification in 2018 also incorporated imaging and pathological findings, unlike the previous clinically staged system.
