According to FIGO 2018 staging, a patient with cervical carcinoma is found on imaging (MRI) to have a tumour extending into the left parametrium but not reaching the pelvic sidewall. No lymph node involvement is identified on PET-CT. What is the correct FIGO 2018 stage?
- A Stage IIIA
- B Stage IIB ✓
- C Stage IIIB
- D Stage IVA
Correct answer: B. Stage IIB
Explanation
FIGO 2018 cervical carcinoma staging: Stage IIB is defined as parametrial invasion without reaching the pelvic sidewall. Stage IIIB requires tumour extension to pelvic sidewall and/or hydronephrosis from ureteral obstruction. Stage IIIA involves lower third of vagina. Stage IVA is invasion of the bladder or rectum. The 2018 revision allows imaging (CT, MRI, PET-CT) and pathological findings to inform staging — a significant change from the purely clinical 2009 system. IIIC staging (lymph node metastasis detected by imaging or pathology) was introduced in 2018.
