A 52-year-old woman has a cervical tumour extending to involve the lower third of the vagina. On rectal examination the parametria are free and the pelvic side walls are not reached. Under FIGO 2018 staging, this disease is classified as:

• A Stage IIIA ✓
• B Stage IIB
• C Stage IIA2
• D Stage IIIB

Explanation

FIGO Stage IIIA is defined by vaginal involvement reaching the lower third without extension to the pelvic wall. Stage IIA describes tumour involving the upper two thirds of the vagina without parametrial invasion, so the lower-third limit decides between IIA and IIIA. Stage IIB requires parametrial involvement and Stage IIIB requires extension to the pelvic wall or hydronephrosis, both explicitly excluded here on clinical examination.
