A 42-year-old woman presents with postcoital bleeding. Colposcopy shows an irregular lesion on the ectocervix. Biopsy confirms invasive squamous cell carcinoma. MRI pelvis shows a 4.5 cm tumor confined to the cervix with no parametrial or vaginal extension. According to FIGO 2018 staging, her stage is:

• A Stage IB2
• B Stage IIA1
• C Stage IIB
• D Stage IB3 ✓

Explanation

FIGO 2018 staging for cervical carcinoma: Stage IB3 = tumor confined to cervix, clinically visible lesion greater than 4 cm in greatest dimension. A 4.5 cm tumor confined to the cervix places this patient in Stage IB3. Stage IB2 is clinically visible lesion 2–4 cm; Stage IIA1 involves upper two-thirds of vagina with tumor ≤4 cm; Stage IIB involves parametrium. FIGO 2018 now allows use of imaging and pathology for staging.
