A 42-year-old woman is diagnosed with cervical carcinoma. Pelvic examination reveals the tumour extends to the pelvic sidewall. MRI confirms no hydronephrosis and no involvement of the lower third of the vagina. According to FIGO 2018 staging, what stage is this?
- A Stage IIB
- B Stage IIIA
- C Stage IIIB ✓
- D Stage IVA
Correct answer: C. Stage IIIB
Explanation
FIGO 2018 Stage IIIB cervical carcinoma is defined by extension to the pelvic sidewall and/or hydronephrosis or non-functioning kidney. Extension to the pelvic sidewall without hydronephrosis is IIIB (not IIIA, which is lower-third vaginal involvement; not IIB, which is parametrial involvement not reaching sidewall). Stage IVA involves the bladder or rectal mucosa.
