A 38-year-old woman is diagnosed with cervical squamous carcinoma. MRI shows a 4.5 cm tumour invading the parametrium on the right side but not reaching the pelvic wall; no bladder or rectal invasion; no lymph node involvement on imaging. According to FIGO 2018 cervical cancer staging (which incorporates imaging and pathology), the stage is:
- A Stage IIIA
- B Stage IIIB
- C Stage IIB ✓
- D Stage IVA
Correct answer: C. Stage IIB
Explanation
FIGO 2018 staging for cervical carcinoma incorporates imaging and pathology findings. Stage IIB = parametrial involvement but not reaching the pelvic sidewall. Stage IIIB = tumour extends to the pelvic wall and/or causes hydronephrosis or non-functioning kidney, or involves pelvic/para-aortic lymph nodes. Since parametrium is involved but the pelvic wall is not reached, this is Stage IIB. The 4.5 cm size alone (without parametrial involvement) would be IB3.
